Abstract

Jaringan jalan merupakan salah satu penunjang kegiatan perekonomian yang bermuara pada peningkatan taraf hidup masyarakat. Kabupaten Tana Toraja memiliki 166 ruas jalan kabupaten dengan total panjang 1,252 km yang sebagian besar (74.24%) berada dalam kondisi rusak. Hal ini disebabkan oleh adanya kebijakan pendanaan karena keterbatasan anggaran, akibatnya semua ruas jalan tidak dapat tertangani seluruhnya, sehingga membutuhkan prioritas jaringan jalan yang perlu ditangani untuk pengembangan wilayahnya ke depan. Penelitian ini menggunakan metode analisis skalogram untuk mengidentifikasi wilayah-wilayah yang menjadi pusat pelayanan dan metode Analytical Hierarchy Process (AHP) untuk mendapatkan persepsi stakeholder terhadap faktor yang menjadi prioritas dalam memilih jaringan jalan yang akan ditangani. Hasil penelitian menunjukkan 2 kecamatan merupakan pusat pelayanan (Hirarki I), 5 kecamatan merupakan subpusat pelayanan (Hirarki II), dan 12 kecamatan merupakan wilayah hinterland (Hirarki III). Dari analisis AHP diperoleh pilihan prioritas jaringan jalan berdasarkan potensi obyek wisata. Sehingga jaringan jalan yang dapat diprioritaskan adalah: 1). Alternatif I, terdiri atas: (i) Jalan lingkar wisata, (ii) Kokkang ? Buakayu, (iii) Pasobo ? Kondodewata, (iv) Tetebassi ? Kondoran, (v) Batupapan ? Rantekurra; 2). Alternatif II, terdiri atas: (i) Jalan lingkar wisata, (ii) Kokkang ? Buakayu, (iii) Pasobo ? Kondodewata, (iv) Tetebassi ? Kondoran, (v) Batupapan ? Rantekurra, (vi) Makale ? Kaduaja.

Abstract

Tangerang sebagai kota penyangga Jakarta memiliki pertumbuhan penduduk yang cukup pesat, sekitar 3 % per tahun. Seiring dengan pertumbuhan penduduk, jumlah sampah yang harus ditangani oleh pemerintah akan meningkat juga. Sebagai sumber sampah terbesar, sampah domestik dari permukiman perlu dikelola sebaik-baiknya. Dengan semangat pengelolaan sampah yang berkelanjutan perlu direncanakan jenis sarana persampahan di setiap jenis permukiman berdasarkan karakter atau perilaku orang dalam penanganan sampah rumah tangga mereka. Tujuan penelitian ini adalah mengidentifikasi tipologi permukiman di Kota Tangerang menurut karakteristik perumahan dan masyarakatnya dalam penanganan limbah domestik serta menentukan kebutuhan sarana persampahan berdasarkan prioritas pada setiap tipologinya. Dalam mengidentifikasi tipologi perumahan digunakan analisis spasial untuk menentukan karakteristik fisik dan dikombinasikan dengan analisis deskriptif untuk mengetahui karakteristik masyarakat, sedangkan untuk menentukan kebutuhan sarana persampahan yang sesuai di setiap jenis perumahan berdasarkan prioritasnya digunakan analisis AHP dan MCDM-TOPSIS. Kombinasi antara karakteristik fisik dan karakteristik masyarakat menghasilkan 12 (dua belas) tipologi permukiman, sedangkan hasil dari analisis AHP dan MCDM-TOPSIS menghasilkan 6 kelompok permukiman yang mempunyai prioritas kebutuhan sarana persampahan yang berbeda-beda berdasarkan pedoman umum 3R di kawasan permukiman

Abstract

Sukabumi development approach which has been more emphasis on economic growth tends to ignore the regional disparities. Therefore, it is necessary to study and identify the direction of regional development policy . By knowing the level of disparity that occurred in this research sought leading sectors and the level of regional development to build of the Sukabumi city. The analytical method used is the Williamson index , Theil index , Location Quotient , Shift Share Analysis , Entropy and Schallogram . From the analysis  is known that there has been a disparities of Sukabumi areas in middle category / uneven . The development of the old town area which consists of a level hierarchy I and II have the balance of diversity and economic sectors better, the leading sector dominated by the tertiary sector which is urban characteristics . While the new city area, including the development of a hierarchy of regions III and leading sectors dominated by primary and secondary sectors which are characteristic of rural areas.Sukabumi development approach which has been more emphasis on economic growth tends to ignore the regional disparities.

Abstract

The change of environmental problem is very complex.  The highest population growth caused supply of land and natural resources to be increased.  If it does not control, it can influence natural resources stock and disturbs environmental balance system land use control is part of Bogor land use planning.  The objectives of this research were (1) to analyze the dynamics of land use and population in the period of 1972-2005 in Bogor Municipality, (2) to develop dynamics model and analyze the relation between the instrument of land use control and the factors related to the sustaina tozbility of Bogor Municipality, and (3) to analyze stakeholders? roles benefited to space control system in Bogor Municipality.  The methods used for this research were (1) GIS analysis to observe the alteration influence landcover in period 1972-2005, (2) dynamic system analysis for landcover using in Bogor Municipality, and (3) AHP analysis to observe stakeholders? role controlling use of landcover in Bogor Municipality.  This research indicate that the dynamic of landcover such as forestry, mixed plantation, and open area (1972, 1983 and 1990) before to be extended were larger than after.  For the landcover change such as resettlement, bush, water and wetland showed that were larger than before extended (2000 and 2005).  The population dynamic analysis showed the optimum increasing on 1985-2020 (22,38%) but was not followed by good landcover use planning as indicated by forestry depletion from 25% to 2%, depletion of mixed plantation from 42% to 36%, resettlement need increased from 12% to 43%, and declining open area from 17% to 2%.  These showed that Bogor developments were unsustainable.  The dynamic analysis showed the correlation between the environmental component and land use control.  Land use control to achieve Bogor sustainable development need many aspect such as land area, population number waste number, vehicle number, the length of roads and the role of stakeholder on land use control system in Bogor municipality though license mechanism and control.  The government can influence land use control at level of controlling and level of licensing.  For the government input as the authority that gives the permission of land using need to be consistent on the regulation they made.   Key words: the dynamic, land use model, and controlling

Abstract

The use of earth worms for composting organic agriculture waste, or vermiculture, has been known since early civilization.  The vermiculture process for organic waste from domestic and commercial sources has been investigated only recently. The objective of vermiculture utilization is to search solution of domestic and industrial waste problems. In this study two species of worms, namely tiger worms  and red worm, were used as decomposers of household wastes. These two kinds of worms converted the household wastes into vermicompost and vermicasting. The most efficient conversion was found in hardbox decomposition (70%), kitchen wastes (66%), mixed fruits and vegetables (58%), and the least was garden leaves (56%).

Abstract

The big potential of Cirebon Regency with good transportation access and demography bonus is able to promote its regional development. Not all of the potential has been optimized to invite investment in Cirebon Regency. One of the causes is some of the lands haven't been registered, so that obstructs investment that requires land. We explore the spatial relationship between the regional development level and land transaction pattern. We calculate the entropy diversification index to see the level of regional development. We also interpolate the land transaction to see the spatial pattern. The natural neighbor interpolation method was used to show spatial patterns of land transactions. Then, we overlay the map of the entropy index and land transaction pattern map to see the relationship spatially. Land transactions in Cirebon Regency gathered in a very developed and developing region. Districts of Palimanan, Depok, Plumbon, Weru, and Plered that are categorized very developed have more quantity of transactions and land transaction value than the undeveloped area. Pasaleman district has Kecamatan Depok, has the smallest entropy index, and categorized as undeveloped has a lower number and value of land transactions. We found a similar spatial pattern between the regional level of development and land transaction interpolation.
