"The title of the thesis is "Land Use Change Analysis of Rice Field in Kabupaten Karawang in the Years of 1989 and 1997 Using Landsat TM Image". Rapid growth of population and various human activities are main causes of land use change of rice field in Kabupaten Karawang. Geographically, Kabupaten Karawang is located in West Java Province, mostly in flat area; having fertile soil comprises of volcanic alluvium, i.e., sand, ash and clay. The area is popular as one of the national rice producing areas. The observation of this thesis was conducted for analyzing land use changes of the years of 1989 and 1997. Within those time periods with the help of Landsat images the changes of land use on rice fields into developed areas are observe able, reducing the area of the total rice fields. The unit analysis is kecamatan. To estimate the changes, this thesis uses a land use changes models, i.e., L = f(Economy, Population, and Policy), where L indicates land use change from rice field into developed area. L is considered as a dependent variable, representing human dimension. The independent variables are economy, population, and policy. These variables were tested with multiple linier regression analysis. The economic variable comprises of PDRB (Regional Gross Domestics Product) of industry, PDRB of cash crops, and PBB (Property Tax). Population variable consists of total population of the of 0 to 74 years old, total farm labors of 10 to 64 years old, and total non farm labor of 10 to 64 years old. Policy variable involves the region of developed area, the number of SD (elementary school), SMP (junior school), and Puskesmas. The analysis of Landsat 5 TM images shows that the highest changes are in Kecamatan Cilamaya and Telukjambe. The less changes are in Kecamatan Pangkalan and Lemahabang. Statistical analysis was applied to get better understanding of the changes of rice fields into developed areas. An equation was used to observe the growth of changes of rice fields into developed area, and the pattern of land change of rice fields into develop area in the year of 1997 to 1989. From the results of statistical analysis it can be concluded that the pattern of land use change of rice fields into developed area in the year of 1997 to 1989 has a significant correlation with the dependent variables. The equation can be used as a model to analyze the changes of the area of rice fields into developed area."

National Parks as nature conservations are defined as areas having natural ecosystems which are managed through zoning systems. These systems are based on the 1990 Act 5 and international regulation and was declared by the IVth World Congress on National Parks and Protected Areas which was held in Caracas, Venezuela, 1992.

Ujung Kulon National Park was declared a World Heritage Site by UNESCO (1992) and registered by The International Union for Conservation of Nature and Natural Resources 1 IUCN Red List Categories (1994) as the last habitat for the "Endangered" Javan Rhinoceros (Rhinoceros sondaicus).

Gap Analysis is a spatial approach of identifying the accuracy of spatial dimension of community species in natural conservation areas. As a spatial approach, Gap Analysis presents a combined methodology provided by Remote Sensing, Geographic Information Systems and Leopold Interaction Matrix Methodology.

The purpose for the study of " Gap Analysis in The Zoning Management System of Ujung Kulon National Park Indicated by Java Rhinoceros(Rhinoceros sondaicus) " was to seek the gap occurring between the zoning management system of Ujung Kulon National Park and a system based on the biogeographically approach and biophysical geography consideration.

The aim of the Gap Analysis approach was to find the ecosystem spatial distribution of Taman Nasional Ujung Kulon by (1) providing the spatial distribution of the sensitive zoning conservation area in Taman Nasional Ujung Kulon, (2) providing the habitat suitability for the Java Rhinoceros (Rhinoceros sondaicus) and (3) to seek the gap width between the sensitive extremely area plus the area of habitat suitability for the Java Rhinoceros (Rhinoceros sondaicus) and the areas defined by the zoning management system of PHPA.

The results of the study indicated the sensitive extremely zoning conservation area is 8.608 ha, the habitat suitability for the Java Rhinoceros (Rhinoceros sondaicus) is 3.734 ha thus a 33,22 % gap occurred between the sensitive extremely area plus the areas of habitat suitability for Java Rhinoceros (Rhinoceros sondaicus) and the area to those defined by the zoning management system of PHPA"

"The area of Bandung municipality was 16,180.65 hectares with a population of 1,806,409 persons; so that it categorized as area with high population density that was 112 persons per hectares noted in 1998. It was implied that the high density of population by land use in 1997, which was more than 70% of this area occupied for settlement and industrial regions. With such populated area, one could expect a huge amount of waste accumulated. Municipal solid waste generated approximately 8,000 m3 per day that was disposed to three disposal sites. These were located at TPA (Tempat[ Pembuangan Akhir) Sampah Leuwigajah, Jelekong and Pasir Impun. These areas operate until the year 2002. Therefore, Bandung municipality should seek a new location for disposal site.To find new disposal site based on scientific considerations, geographical information system and approach were employed. The methods used were overlaying techniques with scoring method. The scoring method consisted of physical and social parameters. To determine the most suitable location, technical measurement was also considered. Solid waste disposed to TPA will be decomposed that create odor, gas and liquid that impact on the environment. Gas, especially methane would be flammable. While, the liquid might produce leachate that will be absorbed by the soil surface. In consequence, it would contaminate the ground water. Therefore, in determining most suitable disposal site one must discern physical and social conditions.According to SK SNI T-11-1991-03 regarding TPA Sampah (Waste Disposal Site) Selection Procedures, physical condition parameters must be considered, e.g. altitude, slope, geological risk, soil type, and water table. While social condition parameters consist of population density, land use, and distance from waste source. Each parameter was scored according to the condition. Then, each thematic map was overlaid one to the other to have strata of the most suitable, suitable and not suitable areas for disposal site based on physical and social parameters.There are 37 most suitable locations that must be analyzed to obtain selected location. Then, technical consideration was applied to determine the selected location. The technical consideration parameters contained location area, water discharge and recharge system, accessibility, and distance from the river, distance from the airport, traffic condition, and windrow. The most important parameter was location area. The measurement for location area with assumption for 15 years of operation period, and eight kecamatan would dispose its waste to the selected location. The eight kecarnatan were Margahayu, Margaasih, Katapang, Dayeuhkolot, Soreang, Cimahi Selatan, Cimahi Tengah and Cimahi Utara. These were highly dense population, so that it would not have its own disposal site. The disposal site area required would be around 212.12 hectares. In conclusion, the proposed, most suitable location for Bandung Municipal Solid Waste disposal site would be the area of 357.49 hectares, which was located in the border of Kecamatan Soreang and Katapang."

"ABSTRAKHutan merupakan sumberdaya alam dan lingkungan yang mempunyai peranan strategis bagi bangsa Indonesia, terutama sebagai pelindung ekosistem flora, fauna dan plasma nutfah. Kepentingan masyarakat terhadap hutan sebagai sumberdaya alam, tidak hanya memberikan ruang atau lahan usaha tani, tetapi juga bermanfaat dalam memberi kesempatan kerja.Berbagai alternatif bentuk pengelolaan hutan terus dikembangkan, salah satunya adalah dengan pengembangan model untuk mendapatkan hasil yang optimal. Pembangunan hutan kemasyarakatan (HKm) untuk selanjutnya disebut dengan HKm, merupakan salah satu alternatif model pengelolaan hutan tanaman yang dikelola bersama antara pemerintah dengan masyarakat sekitar hutan.Banyak uji coba dilakukan pada model HKm, salah satunya adalah uji coba dengan menggunakan program tujuan berganda dengan menitik-beratkan pada variabel sosial ekonomi terutama nilai finansial komoditi. Pada umumnya model yang dikembangkan tersebut kurang berhasil, karena kurang mempertimbangkan kondisi fisik lahan sebagai faktor penentu disamping faktor sosial ekonomi.Studi ini mencoba mengembangkan model HKm optimal. Metode yang digunakan untuk pengembangan model lahan HKm optimal adalah metode survei dengan pendekatan komplek wilayah dalam ilmu geografi. Variabel yang digunakan adalah variabel fisik dan sosek, dan keduanya diperhitungkan sebagai faktor yang memberikan kontribusi sama.Pengembangan model lahan HKm optimal memberikan masukan berupa tingkat kesesuaian lahan terhadap tujuh komoditi dan penyebarannya, serta distribusi spasial lahan HKm optimal dinilai dari faktor fisik maupun sosial ekonomi. Tingkat kesesuaian lahan dalam penelitian ini menghasilkan dua kriteria terhadap tujuh komoditi yang disesuaikan dengan keinginan masyarakat, yaitu: (a) tingkat kesesuaian lahan fisik. (b) tingkat kesesuaian lahan sosial ekonomi. Sedangkan distribusi spasial sebaran lahan HKm optimal, diperoleh tiga kriteria menurut gradasi dari tingkat yang tertinggi sampai terendah tingkat keberhasilannya, yaitu : (a) sebaran lahan optimal I . (b) sebaran lahan optimal II, (c) sebaran lahan optimal III.Kekuatan dari pengembangan model lahan HKm optimal adalah diperhitungkannya kondisi fisik lahan sebagai faktor yang mendukung model hutan kemasyarakatan, dengan diketahuinya sebaran lahan optimal I sampai optimal III dapat memberi informasi keberhasilan dan perlindungan terhadap kelestarian hutan dan kesejahteraan masyarakat.

ABSTRACTOptimum Community Forestry (HKm) Land Modeling Development (Case Study in Labanan Forest Area, Berau District, East Kalimantan Province)Forest has been considered as a natural resources which has strategic role for Indonesian's people, mainly for protecting land and all people, animals and trees who depend on it. Forest as a natural resources not only give space for agriculture sectors, but it can give job opportunities for other sectors.Various alternatives in managing the forest have been developed continuously. Develop in forest modeling has aim to get the optimum yield. Social forestry (later called by Hkm) is an alternative model in managing forest plantation. This model involves government and people around the forest.Several efforts have been done in applying HKm model. One of the model used multi purpose program focusing on financial value of the commodities. Generally, such a model doesn't work successfully. This model was neglecting physical land condition as a critical factor as well as socio economic factor.This research tried to develop the optimum Hkm land modeling. The research methods were done using survey with considering landscape approach of geographical science. Physical and socio economic variable had been counted can give equal contribution.The optimum Hkm land modeling give information on land suitability level for seven commodities and their distribution spatially. There are two criteria for those 7 commodities according to local people perception; those are physical land suitability and socio economic land suitability. The optimum Hkm land spatial distributions have three classes, those are: a). First optimum land distribution, b). Second optimum land distribution, c). Third optimum land distribution.Considering physical factors as a variable in developing Hkm land modeling are the strength point of the optimum Hkm land modeling. The spatial distribution of the optimum Hkm land give information on the success and failure of land utility in order to achieve people prosperity and ensure the forest sustainability.

"In the political analysis, especially in accordance wilh the general election socio-political and socio economic research provides a geographical approach to Analyse Central of Java. Method and geographical elements :are used lo analyse the result of that general election, in which the spatial unitS are used to be analysed. The spatial units consist of 35 regions at kabupaten/kota level.

Vote dislribution of the top five political parties in the General Election of 1999 in every kabupatenlkota of Central Java province is presented through tables and maps. By using the method of Location Quotient, available to produce a vote bases maps, Prom those maps of vote bases, they are overlapped and the distribution of santri and abangan enclaves can be identified. Subsequently, these enclaves are described in a map.

A differentiation on region characteristics of vote gathering distribution among the top five parties is clearly described. In term of typology of region phisiography (high mountains- low land), there is a significant difference of vote gathering for the Party of Golkar, in which Golkar Party is concentrard in Southern Highland. ln term of typology of rural-urban, there is a significant difference of vote gathering for PKB and PAN. PAN is concentrated more in urban areas while PKB is concentrated in rural areas:. Whilst due to typology of coastal-hinterland, Golkar Party is concentrated in Southern Coastal areas while PKB in the Northern Coastal areas. In term of typology of karesidenan, the significant difference of vote gathering can be shown among PDI-P, PK.B, PPP and PAN.

There are 8 factors influencing vote gathering. Those influencing factors are : profession of farmers, the number of people listening to radios, the number of Center of Traditional Islamic Education, the mass bases for "Old" Golkar, young votern, the Muhammadiyah schools, the NU schools. and the welfare perspective, which categorized as the middle and high socio-economic status.

According to sensitivity test, it is found that 12 factors influence vote gathering. By synthesizing those factors , this research enables to describe three geographical entities in explaining the relalion between geographical characteristics and vote distribution. The geographical pattern can be shown as follows :

ln the Southern Coastal regions :

There are 9 factors influencing the vote gathering, are : population density. the farmer profession, number of people listening to radios, number of moslems, the Muhammmadiyah schools., Center of Traditional Islamic Education, mosques and other buildings dor islam praying, number of santri, and the mass of the old Golkar.

In the hinterland regions:

Those 12 factores have a role to influence the vote gathering. They are ; population of density, the age of 17-25 years, the farmer proffesion, second and third wealthy families, people listening to the radios, number of moslems, the NU schools, the Muhamadiyah schools, Center of Traditional Islamic Eduction, mosques and other buildings for Islam praying, number of santri and the mass of Old Golkar.

In the northern coastal regions

Those 12 factors have a role to influence the vote gathering. They are: population density, the age of 17-25 years, the farmer proffesion, second and third wealthy families, people listening to the radios, number of moslems, the NU schools, the Muhammadiyah schools, Center of Traditional Islamic Education, mosques and other buildings for Islam praying, number of santri, and the mass of the old Golkar."

"Rice fields located in Citarum Hilir watershed of Karawang district are more and more affected by growth of residential and industrial areas. This resulted in the need to have supporting rice fields elsewhere including in the upstream region. ln Citarum Hulu watershed, 19,5% fiom the existing rice fields is non-irrigated with 32,l9% of population work in the agriculture sector. But productivity of' non-irrigated rice fields of Citanim Hulu watershed is still low, which is below 25 kwintal/ha. One of the efforts to increase its productivity is to look at the local climate model. The low productivity may also be caused by factors such as slope and altitude, which are used as variables in Wilayah Tanah Usaha (WTU). Sandy (1985) wrote that growth and death of any plant in Indonesia depend on water. Awarding to Chang (1968) every process in a plant is affected by water. Furthermore, FAO believed that the growth requirement of a rice plant is also depended on water availability. Mohr, Schimdt-Ferguson, and Oldeman made climate classifications based on rainfall in relation with plant needs of irrigation. Spatial climate model and planting time/season are important factors in management of non-irrigated rice fields in Citarum Hulu watershed. These rice fields are nou-unifonnly found in the center down to the south. Rice production varies from 22 to 4l kw/ha where the majority produces 30-40 kw/ha. Productivity model for the northem part is varied, and to the south is more stable with productivity of 30-40 kw/ha. The annual average rainfall in Citarum Hulu watershed is 1770-3458 mm/yr where the majority of the region has in the range of 2000-3000 mm/yr. Maximum monthly rainfall is 558 mm and a minimum of 6 mm on average. Rainfall is high in the months of November to April and dry period is fiom June to August. Mol-rr?s climate classification is around class III - Vb where the majority is in class III-IV. Schmidt-Ferguson?s climate classification for this area is type C to type A, where the majority is in the wet type (A). 0Ideman?s climate classification varies from D3 to Bl where the majority ofthe region is in climate group C-B (humid-wet). ln general, climate model for Citarum Hulu watershed is as follows: in the center (around the city of Bandung) is almost always drier than its surrounding areas, specifically in the northem and southem parts that are mountainous. The distribution of non-irrigated rice fields has a strong correlation with the annual rainfall model of Schimdt-Ferguson and Oldeman, because as an area has more precipitation there tend to be non-irrigated rice fields. But it is not true with Mohr climate. A strong correlation in productivity of non-irrigated rice fields with rainfall model, Mohr, Schmidt-Ferguson, and Oldeman climate models mean that as a region receives more precipitation then 'there is a tendency of higher rice productivity. But there is also a tendency that if an area is extremely wet, the productivity will decrease. Planting season in the Citarum Hulu watershed is from October and May with 4 planting time models: October/February, October/March, November/March, and December/April. In the November/March, planting time is dominant in almost all of the watershed area. Part of the non-irrigated rice fields in Citarum Hulu watershed are still according to the WTU conception, that is 65,87%, which the majority is in the center. As for the rest of this region, they should be converted into protected forest areas (especially in the south) and hard plant agriculture (in the cast). Keywords: DAS Citarum Hulu, non-irrigated rice fields, rainfall, climate model, Mohr, Schmidt-Ferguson, Oldeman, WTU conception, planting time."
