REAL ESTATE

Real estate adalah istilah legal yang mencakup lahan beserta sarana perbaikannya, seperti bangunan, pagar, sumur dan

perbaikan tapak lainnya yang menetap di lokasi – tidak bergerak.

In some situations the term "real estate" refers to the land and fixtures together, as distinguished from "real property", referring to ownership of land and appurtenances, including anything of a

permanent nature such as structures, trees, minerals, and the interest, benefits, and inherent rights thereof.

Real property is typically considered to be Immovable property The terms real estate and real property are used primarily in

common law, while civil law jurisdictions refer instead to immovable property.

Residential real estate

Major physical categories include: Attached / multi-unit dwellings

Apartment - An individual unit in a multi-unit building. The boundaries of the apartment are generally defined by a perimeter of locked or lockable doors. Often seen in multi-story apartment buildings.

Multi-family house - Often seen in multi-story detached buildings, where each floor is a separate apartment or unit.

Terraced house (a.k.a. townhouse or rowhouse) - A number of single or multi-unit buildings in a continuous row with shared walls and no intervening space.

Condominium - Building or complex, similar to apartments, owned by individuals. Common grounds are owned and shared jointly. There are townhouse or rowhouse style condominiums as well.

Cooperative (a.k.a. "co-op) - A type of multiple ownership in which the residents of a multiunit housing complex own shares in the cooperative corporation that owns the property, giving each resident the right to occupy a specific apartment or unit.

Residential real estateMajor physical categories include:

Semi-detached dwellings : Duplex - Two units with one shared wall.

Single-family detached home

Portable dwellings :Mobile homes - Potentially a full-time residence which can be (might not in practice be) movable on wheels. Houseboats - A floating home Tents - Usually very temporary, with roof and walls consisting only of fabric-like material.

CONDOMINIUM

A condominium, or condo, is the form of housing tenure and other real property where a specified part of a piece of real

estate (usually of an apartment house) is individually owned while use of and access to common facilities in the piece such

as hallways, heating system, elevators, exterior areas is executed under legal rights associated with the individual

ownership and controlled by the association of owners that jointly represent ownership of the whole piece.

Colloquially, the term is often used to refer to the unit itself in place of the word "apartment".

“Condominium” dapat didefinisikan secara sederhana sebagai suatu "apartment" yang dimiliki oleh penghuninya , bukan

“sewa”.

Page 7: Diabstraksikan dan dihimpun  :   Nur  WPM,  Ardy W.S.  dan Soemarno ,  pslp-ppsub  2012

CONDOMINIUMA condominium is a collection of individual home units along

with the land upon which they sit. Individual home ownership within a condominium is construed as ownership of only the air space confining the boundaries of

the home . The boundaries of that space are specified by a legal document known as a Declaration, filed of record with the local governing

authority. Typically these boundaries will include the drywall surrounding a room, allowing the homeowner to make some interior modifications without impacting the common area.

Anything outside this boundary is held in an undivided ownership interest by a corporation established at the time of

the condominium’s creation. The corporation holds this property in trust on behalf of the homeowners as a group–-it may not

have ownership itself.

Page 8: Diabstraksikan dan dihimpun  :   Nur  WPM,  Ardy W.S.  dan Soemarno ,  pslp-ppsub  2012

CONDOMINIUM

A condominium consists of multi-unit dwellings (i.e., an apartment or a development) where each unit is individually

owned and the common areas, such as hallways and recreational facilities, are jointly owned (usually as "tenants in

common") by all the unit owners in the building. A condominium also consists of bylaws that all the home owners

are supposed to follow such as indoor noise control.

It is also possible for condominiums to consist of single family dwellings: so-called "detached condominiums" where homeowners do not maintain the exteriors of the dwellings, yards, etc. or "site condominiums" where the

owner has more control and possible ownership (as in a "whole lot" or "lot line" condominium) over the exterior appearance. These structures are

preferred by some planned neighborhoods and gated communities.

APARTMENTAn apartment (in American English) or flat (in British

English) is a self-contained housing unit (a type of

residential real estate) that occupies only part of a

building. Such a building may be called

an apartment building or apartment house, especially if it consists of many apartments

for rent. Apartments may be owned by an owner/occupier or rented by tenants (two types of housing

tenure).

Apartment types and characteristics

Apartments can be classified into several types.

In North America the typical terms are a studio or bachelor apartment

(efficiency or bedsit in the UK). These all tend to be the smallest

apartments with the cheapest rents in a given area.

These kinds of apartment usually consist mainly of a large room which is the living, dining, and

bedroom combined. There are usually kitchen facilities

as part of this central room, but the bathroom is its own smaller

separate room.

Pengertian Apartemen

1. Apartemen adalah ruang atau sekelompok ruang kamar yang dimaksudkan sebagai pemukiman (tempat tinggal); biasanya salah satu dari banyak kelompok yang sama di dalam gedung yang sama.

2. Apartemen adalah suatu kelompok ruang yang mempunyai kelompok unit yang sama dirancang khusus untuk hunian.

3. Apartemen adalah semua unit hunian tempat tinggal keluarga kecuali sebuah rumah tinggal berdiri sendiri sabagai satu keluarga.

4. Apartemen adalah bangunan yang terdiri dari tiga unit atau lebih rumah tinggal di dalamnya dan merupakan suatu kehidupan bersama pada lingkungan tanah terbatas, dan masing-masing unit hunian itu dapat dimiliki atau dibangunan terpisah.

5. Apartemen adalah kamar atau beberapa kamar atau ruangan yang diperuntukkan sebagai tempat tinggal, terdapat di dalamnya suatu bangunan yang biasanya mempunyai kamar atau ruangan-ruangan lain semacam itu.

Villa hidyatullah merupakan sebuah yayasan amal bakti santri pondok

pesanteren Hidayatullah. Berdiri sejak akhir dekade tahun 90 an. Pada mulanya Villa yang terletak di jalan Indragiri VI desa Sumberejo, Kota Batu Jawa Timur ini

didedikasikan sebagai wadah menuntut ilmu umat yang ingin memperdalam ilmu agama

dan dakwah.

Namun seiring dengan perkembangan dan keinginan kemandirian yayasan, maka

masuk era tahun 2000 awal, salah seorang santri dengan dukungan jamaah Hidayatullah berinisiatif untuk

mengembangkan lokasi Diklat hidayatullah menjadi sebuah sarana open public yang

memberikan fasilitas kondusif bagi pengembangan SDM yang berpadu dengan

rihlah atau rekreasi.

GARDEN APARTMENTA garden apartment complex consists of low-rise

apartment buildings built with landscaped grounds surrounding them.

The apartment buildings are often arranged around courtyards that are open at one end.

A garden apartment has some characteristics of a townhouse: each apartment has its own building

entrance, or just a few apartments share a small foyer or stairwell at each building entrance.

Unlike a townhouse, each apartment occupies only one level.

Page 13: Diabstraksikan dan dihimpun  :   Nur  WPM,  Ardy W.S.  dan Soemarno ,  pslp-ppsub  2012

Modern garden apartment buildings are never more than three stories high,

since they typically don't have elevators/lifts.

However, the first "garden apartment" buildings in the United States, developed in the early 20th century, were

five stories high.Some garden apartment

buildings place a one-car garage under each

apartment. The grounds are more landscaped than for

other modestly scaled apartments.

GARDEN APARTMENT

A garden apartment is a living unit located at ground level on property that is usually landscaped.

Although the term garden apartment is often used loosely to describe any first floor apartment such as one in a high rise or basement, a true garden apartment has no household above

it. Garden apartments are not vertically stacked, but rather horizontally spread out in an open area that may have a

courtyard. Garden apartments are found all over the world.

Attractive garden apartments have well cared-for grounds with flowers and trees. The owners of the apartment property are

responsible for the upkeep of the outdoor areas. If an area for dogs is included, then tenants are responsible for cleaning up

after their pets. Some garden apartments may include a small yard, but most have a patio. A garden apartment patio can be a nice place to have a barbecue or outdoor meal or just enjoy some fresh air

if the grounds are well maintained.

Konversi lahan sawah menjadi perumahan, terjadi di kawasan pinggiran kota

Faktor Penyebab Konversi Lahan Sawah

Menurut Pasandaran (2006), paling tidak ada tiga faktor, baik sendiri-sendiri maupun

bersama-sama yang menentukan konversi lahan sawah, yaitu:

1.Kelangkaan sumberdaya lahan dan air2.Dinamika pembangunan3.Peningkatan jumlah penduduk.

Foto . smno-2011

Menurut Irawan (2005), konversi lahan pertanian

pada dasarnya terjadi akibat adanya persaingan

pemanfaatan lahan pertanian dengan non-

pertanian. Sedangkan persaingan

pemanfaatan lahan muncul akibat adanya

tiga fenomena ekonomi dan sosial yaitu :

a) keterbatasan sumberdaya lahan,

b) pertumbuhan penduduk, dan

c) pertumbuhan ekonomi.

Lessons In Sustainable Land Development

Increased rates of deforestation, unsustainable agricultural land

use, and severe soil degradation are creating widespread poverty

and environmental degradation in developing countries.

Each day; the world loses about 125 square miles of its forests. That’s 34.5 million acres or 14

million hectares every year Most of this takes place in the developing countries of the humid tropics.

Reforestation efforts are limited to only about 10% of the total area

and most efforts are not promising.

Penyebab Global Warming: Deforestasi, terutama hutan tropis untuk kayu, pulp, dan

lahan pertanian.

Penggunaan hutan untuk bahan bakar (baik kayu dan arang) merupakan salah satu penyebab

deforestasi. Di seluruh dunia pemakaian produk kayu dan kertas semakin meningkat, kebutuhan

akan lahan ternak semakin meningkat untuk pemasok daging dan susu, dan penggunaan lahan hutan tropis untuk komoditas seperti perkebunan kelapa sawit menjadi penyebab utama terhadap

deforestasi dunia. Penebangan hutan akan mengakibatkan pelepasan karbon dalam jumlah

besar ke atmosfir.

Page 19: Diabstraksikan dan dihimpun  :   Nur  WPM,  Ardy W.S.  dan Soemarno ,  pslp-ppsub  2012

Lessons In Sustainable Land Development

Every year, the equivalent of 40 billion tons of carbon dioxide enters the global atmosphere, the result of the ever-increasing use of fossil

fuels. This increase in atmospheric carbon, in combination with the loss of forests has

combined to make global climate change worse.

Lessons In Sustainable Land

Development

The adoption of sustainable agriculture is often proposed

as a solution to these problems.

Sustainable agriculture is concerned with agricultural

practices that are economically viable, meet human needs for food, are

environmentally friendly, and improve quality of life.

Agroforestry is one such land use practice that maintains sustainability at its core.

Maksimalisasi Tutupan Hijau Lahan dengan Agroforestry

Agroforestry : penggunaan lahan, dimana tanaman keras berkayu (pepohonan, perdu, palem, bambu, dsb) ditanam secara bersamaan dalam unit lahan yang sama dengan

tanaman pertanian dan/atau ternak, dengan tujuan tertentu, dalam bentuk pengaturan ruang atau urutan waktu, dan didalamnya terdapat interaksi ekologi dan ekonomi di

antara berbagai komponen yang bersangkutan.

Lessons In Sustainable Land Development

Deforestation is a major unsustainable land use practice. Yet

little is being done to address its economic, environmental and

ecological impact. Clear-cut logging, uncontrolled brush and forest fires, and traditional slash

and burn agricultural techniques have damaged the environment as well as

the agricultural resource base. Additionally, every year, reforestation

efforts that intend to help communities are actually assisting in

planting the wrong types of tree species, resulting in long term

damage. This concerns all of us, especially the families who rely on

trees for the basic necessities of life: fuel, water, food, building materials,

and the air we breathe. Diunduh dari sumber: http://rianyudistira13.blogspot.com/2010/10/penggundulan-hutan.html…

Penggundulan Hutan Manusia selalu menebang pohon tanpa

mempertimbangkan keseimbangan alam. Penebangan secara sembarangan meliputi kegiatan penebangan,

pengangkutan dan penjualan kayu yang tidak sah dan tidak mendapat izin dari otoritas setempat. Hal ini berakibat buruk untuk hutan dan juga lingkungan hidup: tanah longsor, banjir, dan juga kekurangan

oksigen.

CUTTING TREES NOT BAD

Cutting trees is NOT a bad thing. Trees are an

important resource for everyone on earth. The problem is when people

cut trees but do not replant them.

Trees are cut for many reasons. Industries based

on construction and making items such as

furniture (beds, tables) are- always in need of valuable

hardwood trees. Diunduh dari: http://texastreeplanting.tamu.edu/PlantTreeProperly.html

Lessons In Sustainable Land Development

CUTTING TREES NOT BAD

Wood (sometimes in the form of charcoal) is the major source of cooking fuel for over half of the

world (FAO 1999). Because populations and industries in every

country are growing, there is always a growing pressure on

forest resources.

Slash-and-burn agriculture, characterized by periodic burning of the land both to get rid of weeds and to use the ash as fertilizer, is also contributing to the rapid loss

of the world’s forests.Diunduh dari sumber:

Lessons In Sustainable Land DevelopmentCUTTING TREES NOT

BAD

Brush and forest fires not only inhibit the

regeneration of tree seedlings (though some

grasses, trees and shrubs have evolved the ability to

regenerate after fires), they also destroy what

little organic matter remains in the soil.

Fires are often caused by smoking and cigarettes,

unskilled beeking techniques, and

uncontrolled burning of fields for cultivation and

grazing.

Planting LocationA properly planted and maintained tree will grow faster and live longer.

Optimum planting time is early spring after the ground is thawed and before the tree begins to actively develop foliage. This is the time to plant bare root

trees.

SOME TREES CAUSE LONG TERM DAMAGE

In the global program of Trees for the Future, we provide seeds of multi-purpose, fast-growing

(MPFG) trees.

In order to extend the program into many

climatic zones, and to make it more beneficial to the participants, we are constantly looking for

promising species, but we approach this with a great

of care when making recommendations.

SOME TREES CAUSE LONG TERM DAMAGE

Eucalyptus trees grow rapidly into true trees at a wide range of

elevations, soils, and climatic conditions.

They sustainably produce fuelwood and timber suitable for many local construction needs,

and they produce oil used in some medications and other

products,

But eucalyptus trees do not lend themselves to sustainable land

management systems

(Lisanework and Michelson, 1993).

Eucalyptus TreesPlantations are not meant to support a complex

ecosystem. A successful plantation species has to grow fast, have adequate wood properties and be resistant to disease when grown as a monoculture. The eucalyptus

can also become needy of room and produce extra vegetation and dominate areas where they are not

welcome. Eucalyptus trees and hybrids of eucalyptus usually have a high productivity.

SOME TREES CAUSE LONG TERM DAMAGE

Farmers quickly discovered that eucalyptus trees are causing problems with their roots by taking all available water and

nutrients from neighboring trees and crops, and also their leaves,

which blanket the ground, inhibiting new growth.

Eucalyptus trees inhibit the growth of other vegetation,

exposing soils to erosion, and causing lakes and ground water

to disappear with their aggressive roots.

. More than 4 billion Eucalyptus trees of over 150 species grow in the different climates of

Brazil.

SOME TREES CAUSE LONG TERM DAMAGE

Pine trees which are planted throughout much of the world for

their valuable timber present a similar problem. Beneath pine

trees, you will rarely find a productive understory; you tend to

find a blanket of acidic needles that inhibit the growth of

everything. The needles are also a great fuel

for forest fires.

Pine trees do have their benefits, but like eucalyptus trees, they do

not lend themselves to sustainable land management systems.

These trees can leave soils in much worse condition than when

they were planted.

Allelopathic Effects of Pinus halepensis Needles on Turfgrasses and Biosensor Plants

Panayiotis A. Nektarios, Garyfalia Economou and Christos AvgoulasHortScience February 2005 vol. 40 no. 1 246-250.

Fresh, senesced, and decaying pine needles from Pinus halepensis were evaluated for their allelopathic potential on

Festuca arundinacea, Cynodon dactylon and the biosensor plants Avena sativa and Lemna minor through in vivo and in vitro studies. The in vivo study was performed in growth chambers, using 6, 12,

and 18 g of pine needle tissue mixed with screened perlite as a substrate. The effects of the different pine needle types were

evaluated by determining the total root length, total root surface, root dry weight, total shoot length, total shoot surface, and shoot

dry weight. The in vitro study was performed in Petri dishes where seeds from each species were subjected to an increasing

concentration of pine needle extract. The extracts were obtained from pine needle ground tissue that was diluted with water and

either shacked at room temperature or placed in water bath at 40 °C for 24 h. The evaluation of the allelopathic potential was

performed with the determination of radicle length. The allelopathic potential of the pine needle tissues was confirmed

with bioassays using oat (A. sativa) and duckweed (L. minor). The results strongly suggested the allelopathic potential of the pine needle tissue, being more pronounced in the fresh, moderate in

the senesced, and low in the decaying pine needles. The allelopathic substances were species-specific, and the inhibition

resistance of the species tested followed the order F. arundinacea > C. dactylon > A. sativa. The inhibition of the L. minor suggested that the water soluble phytotoxic compounds were inhibitors of

Photosystem II.

SOME TREES CAUSE LONG TERM DAMAGE

In any program of Trees for the Future,

it encourage communities to plant multipurpose fast

growing trees that not only produce useful products

within a short time, but also encourage the growth of field crops, vegetables, and other

vegetation around them.

WATER AND SOIL

Chemical fertilizers and insecticides are unsustainable, temporary solutions that rarely improve the quality of the soil. Pesticides often kill many of the insects and microbes in soils

that are needed for natural processes. There are, in fact, many beneficial insects that eat many of the

pest insects, but most insecticides kill everything indiscriminately.

Furthermore, insecticides get concentrated from smaller insects to the larger animals that eat them, ultimately poisoning the

entire food chain. Alternatives to pesticide use entail (1) giving crops the strength they need to resist infestation by adding nutrients and organic matter to the soil, and (2) using Integrated Pest Management

techniques that ward off and kill insects.

Page 32: Diabstraksikan dan dihimpun  :   Nur  WPM,  Ardy W.S.  dan Soemarno ,  pslp-ppsub  2012

WATER AND SOILFertilizers also cause long term damage, and are often

inadequate in their nutrient composition. Soil need rich organic matter in the form of humus, compost,

manure, etc. Commercial fertilizers, often in the form of NPK pellets, contain

just nitrogen, potassium, and phosphorus. These are three of the major nutrients, but there are also plenty of other nutrients –

such as manganese, iron, boron, zinc, and copper – that chemical fertilizers tend not to contain.

Furthermore, rains can immediately leach these chemical fertilizers down through the soil, contaminating groundwater and

forcing farmers to apply more fertilizer every year.

Page 33: Diabstraksikan dan dihimpun  :   Nur  WPM,  Ardy W.S.  dan Soemarno ,  pslp-ppsub  2012

SOIL AND FERTILIZERGreen manures are sustainable alternatives to chemical

fertilizers. Agricultural crops which received green manure of Gliricidia

sepium (kakawate) yielded 9.5 tons per hectare of corn in Oromia, Ethiopia.

A similar yield was obtained from plots which received green manure of ipil-ipil and Leucaena diversifalia, but a significantly ‘reduced yield was obtained from plots receiving recommended

levels of chemical fertilizer. This implies that the use of multipurpose fast growing

agroforestry species as a green manure can boost grain production over levels obtained from chemical fertilizer.

Additionally, the multipurpose species provide the farmer with fruit, fuelwood, fodder and construction wood.

The effects of potential land development on agricultural land prices

We conduct a national-scale analysis of the determinants of agricultural land values.

The empirical model of agricultural land prices is estimated with a cross-section on approximately three thousand counties in the contiguous US.

The results provide evidence that option values associated with irreversible and uncertain land development are capitalized into current farmland

values. For each county, we decompose the current agricultural land value into

components measuring rents from agricultural production and rents from future land development.

markets, we derive a reduced-form expression for agricultural land values

in terms of observable variables.

The estimated model, together with a spatial interpolation algorithm, is used

to generate a surface of estimated development rights values for Orange

County.

This approach overcomes several problems that arise with the use of

standard appraisal methods to value conservation easements.
