Abstract

Agribusiness of herbal medicine is more important in the future due to raw material pharmaceutical industry tends to usematerials naturally produced To develop herbal medicine with high quality requires the criteria of land suitability based onyield quality, which is represented by active compounds. The compounds are resulted from secondary metabolite that isrelated to environmental conditions. The purpose of this study was to generate the land suitability criteria for curry withcurcuma production base. A total of 49 curry plantation sites were sampled for plant age, productivity, and landcharacteristics, as well as soil and rhizome samples for laboratory analysis. Age-adjusted curcuma production was used as the yield response, which were plotted against land characteristics. Boundary lines confining the resultant scatter of points were then mathematically described. The boundary lines defined curcuma yields that may occur under a given set ofconditions and could be used to determine land suitability criteria. The criteria were done by using projection of lineintersection between boundary line and yield cut off. Land characteristic and curcuma yield relationships had similar pattern, the scalier data were more skewness with higher yields and the scalier confined by boundary lines. By using the lines, every land characteristics that were studied, could be determine to establish land suitability criteria for curry, except for wateravailability and aluminum saturation.

Abstract

Regarding environmental degradation in Puncak and its surrounding area due to the rapid landuse changes during 1981-1994, some mitigation schemes for soil erosion have been implemented but landslides. Data on landslide and its causative factors (landuse, soil, geology, slope, climate, and terrain mapping unit) and their relationships in the area are still not available. The objective of this research is to develop method and procedure to map landslide hazard by using GIs(Geographical Information System) univariate-statistical analysis applied on the area as a case study.For this purpose, three methods to classify and to map landslide hazard were evaluated. They were respectively developed by considering: (a) unweighted density total number of landslide, Method#l, (b) density total number, weighting value, and age of landslide, Method#2, and (c) density totalnumber, weighting value, age, and activity level of landslide, Method#3. The density number is counted by overlying´each of the landslide maps and each of the causative factors maps used, and from this step the weighting value is derived. The resulting density number of landslide given as cumulative percentage and the corresponding weighting value were then plotted on an X-Y graph. From the graph, the level of landslide hazard is classified by applying: (1) standard classificationprocedure as the default statistical analysis given by the software used, and (2) natural classification procedure as it based on the nature of the curve slope of the cummulative graphic. The result given by the three methods were varied but in general they gave landslide hazard map with a similar pattern in which the very high and very low hazard level in the study area increased during the period of 1981- 1994. Of the three methods, applying the natural classification gave a better result than that of the standard classification procedure. Method#2 and Method#3 were better than Method#l in predicting the future landslide occurence. Apparently, MethoM3 should show the best result but the effect of conversion from raster to vector data in GIs significantly reduced the quality of the resulting map.

Abstract

Dewasa ini penggunaan teknologi informasi di segala bidang berkembang pesat, karena sangat membantu pengguna untuk mengolah data dan memperoleh informasi dengan cepat, tepat dan akurat.  Sistem informasi geografis adalah salah satu penggunaan teknologi informasi untuk mengolah peta dalam bentuk digital, sehingga memudah peta tersebut dimanipulasi dan diolah datanya.Tindak kejahatan banyak terjadi di berbagai tempat dengan waktu kejadian yang berbeda, menyebabkan sulitnya menentukan daerah mana yang memiliki tingkat kerawanan tindak kejahatan. Informasi tentang banyaknya tindak kejahatan sangat dibutuhkan oleh masyarakat dan penegak hukum dalam hal ini jajaran kepolisian.  Bagi semua pihak seperti masyarakat luas, informasi ini sangat berguna untuk tindakan antisipasi, khususnya bagi kepolisian membantu dalam mengambil keputusan apakah suatu daerah memerlukan pengawasan ekstra atau tidak, selain itu informasi tersebut dibutuhkan untuk mengetahui intensitas tindak kejahatan.Penelitian ini mencoba mengembangkan suatu sistem informasi yang mampu menampilkan peta secara multilevel serta memetakan jumlah tindak kejahatan yang terjadi di dalam peta dalam bentuk yang beragam. Pengelompokan pada masing-masing daerah diambil berdasarkan ciri-ciri tertentu sehingga output yang dihasilkan diharapkan akan memudahkan pengguna dalam membedakan tingkat kerawanan antara daerah satu dan lainnya dan juga menampilkan grafik dan perhitungan jumlah tindak kejahatan yang terjadi. Visualisasi peta dan grafik pada sistem ini diharapkan akan membantu masyarakat dan memudahkan Kepolisian Resort Kota Bogor dalam menganalisis tingkat kerawanan di tingkat kota, kecamatan maupun  di level yang lebih kecil yaitu kelurahan sehingga sistem ini bisa mengolah data kriminalitas secara cepat, tepat dan akurat.

Abstract

Halmahera Timur merupakan salah satu kabupaten di Provinsi Maluku Utara dengan potensi sumberdaya mineral yang besar yaitu pertambangan nikel. Namun, sumberdaya mineral yang tersedia belum memberikan dampak yang berarti bagi pertumbuhan ekonomi. Vegetasi tutupan lahan semakin berkurang dengan adanya aktivitas penambangan dan jumlah produksi pertanian tiap kecamatan terganggu. Penelitian ini bertujuan untuk memanfaatkan lahan pascatambang nikel yang mendukung perkembangan wilayah melalui beberapa pendekatan yaitu : analisis dan prediksi perubahan tutupan lahan; evaluasi tingkat perkembangan wilayah dari data PDRB dan identifikasi sektor basis tiap kecamatan; membuat skenario penggunaan lahan pascatambang nikel. Penelitian ini memperlihatkan perubahan tutupan lahan terjadi pada kelas hutan dan kebun campuran yang terkonversi menjadi bukaan tambang, sawah dan tegalan/semak/belukar terkonversi menjadi permukiman. Selain itu, sektor basis tiap kecamatan menurun dari hasil produksi karena ada konversi lahan, seperti kelas kebun campuran menjadi kelas bukaan tambang. Perubahan ini tidak diikuti dengan peningkatan ekonomi wilayah yang tinggi. Tren perkembangan ekonomi wilayah periode 2000-2010 menunjukkan peningkatan yang rendah yaitu 0,8%. Perkembangan ekonomi wilayah dan sektor basis tiap kecamatan di Kabupaten Halmahera Timur belum berkembang, sehingga perlu adanya skenario perencanaan penggunaan lahan pascatambang nikel yang sesuai dengan fungsi ruang yaitu tanaman pangan, perkebunan rakyat, hutan tanaman rakyat,dan hutan.Kata Kunci : Perencanaan Penggunaan Lahan, Lahan Pascatambang, Sektor Basis, Pengembangan Ekonomi Wilayah.ABSTRACTEast Halmahera is one of the regency in North Maluku Province with great mineral resource potential especially nickel mining. However, these mineral resources have not provided a significant impact to the economic growth. Vegetation of land cover decreased in the presence of mining activities and the amount of agriculture production from each sub district is disrupted. This study aims to utilize post-mining land of nickel supporting regional development, through a few parameters, namely : analysis and prediction of land cover change; evaluation of regional growth rate of GDP and identifying leading sector in each sub district; making scenario of ex-nickel mining land. This study showed land cover occurred on the forest class and mixed plantation class converted to land clearing mines, paddy and moors / bush / shrubconverted to settlements. Beside that, leading sector of each sub district decreased of existing production due to land conversion, such as mixed plantation class to be class of mine openings. These changes were not followed by regionaleconomy development. The trend of regional economic development of the period 2000-2010 showed a low increase of 0,8%. Regional economic growth and leading sector each sub district in East Halmahera Regency is undeveloped, so that this needs the presence of scenarios for land use planning of ex-nickel mining appropriate with the spatial function namely food crops, smallholder plantations, community plantation forests, and forest.Keyword : Land Use Planning, Ex-Mining Land, Leading Sector, Regional Economic Development.

Abstract

The Ground Water Level plays an important role in determining the greenhouse gas emission and, in turn, in regulating global climate system. Information on existing water levels is still using field measurements. The purpose of this study was to evaluate the best approximation model for estimating water level using drought index. This study utilizes Landsat 8 data to calculate Normalized Difference Water Index and Visible and Shortwave infrared Drought Index for 3 months (March, April and June 2016). The best estimation model is selected by the Akaike Information Criteria correction method and validated using K-Fold cross-validation. The results of this study indicate that the estimation of water level is affected by both drought indices with the TMA (mm) equation= -439,47 – 1639,7 * NDWI_Maret – 640,23 * NDWI_April + 477 * VSDI_Maret. Estimated water level began to detect hotspots ranging from 64,35 ± 36,9 6 cm (27 - 101 cm). The critical point for KHG Sei Jangkang - Sei Liong is 27 cm, thus the water level depth should be maintained less than that to avoid fire in peatlands.ABSTRAKTinggi muka air tanah lahan gambut atau secara teknis dikenal dengan kedalaman muka air tanah memegang peran penting dalam menentukan emisi gas rumah kaca dan mengatur sistem iklim global. Informasi tentang tinggi muka air yang ada saat ini masih menggunakan hasil pengukuran lapangan. Tujuan penelitian ini adalah mengevaluasi model aproksimasi terbaik untuk estimasi tinggi muka air dengan menggunakan indeks kekeringan. Penelitian ini memanfaatkan data Landsat 8 untuk menghitung Normalized Difference Water Index dan Visible and Shortwave infrared Drought Index selama 3 bulan (Maret, April dan Juni 2016). Model estimasi terbaik dipilih dengan metode koreksi Kriteria Informasi Akaike dan divalidasi menggunakan validasi silang K-Fold. Hasil penelitian ini menunjukkan bahwa estimasi tinggi muka air dipengaruhi oleh kedua indeks kekeringan tersebut dengan persamaan TMA (mm) = - 439,47 – 1639,7 * NDWI_Maret – 640,23 * NDWI_April + 477 * VSDI_Maret. Estimasi tinggi muka air mulai terdeteksi adanya hotspot berkisar antara 64,35±36,9 6 cm (27 – 101 cm). Titik kritis untuk KHG Sei Jangkang – Sei Liong adalah 27 cm, dengan demikian kedalaman tinggi muka air harus dipertahankan kurang dari itu untuk menghindari terjadinya kebakaran di lahan gambut.

Abstract

Economic development in Indonesia since 1980s is dealing with conversion of agricultural land to industry, housing, and other sector in city and its periphery. Land conversion have a great impact to food production rather than the impact from technical problem (drought and pest problem). Government need to preserve agricultural land in order to maintain food production. Thus government made a mandatory approach byissued Law No. 41 year 2009. The aim of this research are to identify an actual socioeconomic characteristics in the area of land preservation program (LP2B) in Kuningan Regency, to identify farmers perception on LP2B and to analyze socioeconomic suitability in the areaof LP2B program. Data were analyzed by descriptive statistics and likert scale. Based on the result, there are nine socioeconomic indicator on land preservation program (LP2B) in Kuningan Regency, namely; land conversion rate, food balance, disparity between farm and non-farm income, agriculture households, agriculture labor, farmers’ groups, spatial planning policies and farmers perceptions. Farmers have a positive perception on LP2B program. Land preservation program (LP2B) priority should be donein Cilimus sub district due to low support of socio economic characteristic. Meanwhile Ciawigebang and Cibingbin sub district become a next priority of preservation.Keyword : farmer’s perception, food security, land conversion, socioeconomic of LP2B
