Modeling Land Use/Land Cover Change in Berau Pantai Forests, Berau Regency, East Kalimantan Province
Get PDFLand demands increase with the rise of population and regional development. This results in considerable pressure on forest resources which is characterized by an increasing rate of deforestation. To further explore the impact of deforestation and forest management in regional planning process, this study specifically aimed 1) to identify patterns of land use/land cover changes, 2) to analyze driving factors and 3) to model future land use/land cover. This study employed Landsat imageries to construct land use/land cover maps and their variation across time. Driving factors were analyzed using binary logistic regression. Land use prediction was made through Artificial Neural Network approach. Multitemporal analysis indicated that the research area experienced a decreasing trend of natural forest and shrubs, with substantial extension of existing plantation forests, plantations, agricultural lands and settlements. Indicated driving factors included accessibility, slope class, soil type, forest permit, forest function, RTRW and population density. A forecast in 2030 suggested that natural forests and built-up land would increase from current figures
Mapping of landslide vulnerability in the build area based on Remote Sensing and GIS in Ambon City, Indonesia
Get PDFLongsor lahan merupakan bahaya alam yang berupa pergerakan suatu massa batuan, pecahan batuan (debris), atau tanah pada lereng di bawah pengaruh gravitasi. Dalam mengkaji penelitian ini, metode kualitatif dan kuantitatif digunakan dengan pendekatan spatial untuk menganalisis data primer dan data sekunder yang diperoleh dari citra satelit, observasi, dan instansi terkait. Pengolahan data dilakukan dengan menggunakan software Global Mapper 20, Arcgis 10.8.1 dan Ermapper 8.1. Hasil yang diperoleh dari penelitian ini memperlihatkan kerawanan dari longsor lahan cukup tinggi dengan areal wilayah yang luas sekitar 51.63%, daerah ini tersebar pada wilayah perbukitan. Untuk lahan terbangun dengan tingkat kerawanan longsor lahan baik pada kategori tinggi dan sangat tinggi yaitu pada zona Z-4 dan Z-5, yang disebabkan oleh kemiringan lereng 25 sampai > 40%, dengan jenis batuan yang memiliki tingkat pelapukan tinggi, dan terdiri dari tutupan lahan berupa lahan terbangun yang menambah bobot yang lebih pada lereng. serta kapasitas menahan tanah yang rendah sehingga peka terhadap erosi yang terjadiLandslides are natural hazards characterized by rock mass, debris, or soil movement on slopes under gravity. This study employed qualitative and quantitative methods with a spatial approach to analyze primary and secondary data obtained from satellite imagery, observations, and relevant institutions. Data were processed using Global Mapper 20, ArcGIS 10.8.1, and ER Mapper 8.1 software. The results obtained from this study revealed that the majority of the Ambon City area (approximately 51.63 %) was classified as having high landslide vulnerability. Meanwhile, only approximately 16.26% of the total area had very low or low landslide vulnerability. The same pattern is observed in built-up areas, where most landslide vulnerability falls under the high category (Z-4), at approximately 39.01%. In contrast, very low landslide vulnerability (Z-1) accounted for approximately 35.09%, and low vulnerability (Z-2) accounted for approximately 11.89%. The level of landslide vulnerability in the built-up areas also highlights that most of the Ambon City area, with mountainous terrain accounting for approximately 89% of the total area, experienced relatively high occurrences. In response, the government and relevant authorities must undertake careful spatial planning, direct development towards safer places, and implement policies that support sustainable development
Organic Farming in Bogor, West Java, Indonesia: Measuring How far Its Sustainability
Get PDFSustainable organic farming management combines ecological/environmental, economic, and social interests in its implementation. This study aims to determine the sustainability status of organic agriculture in Bogor, West Java Province, on the ecological, economic, and social dimensions. The analytical method used is Multi-Dimensional Scaling (MDS) through the Rap-Organic Farm (Rapid Appraisal for Organic Farm) ordinance technique. The results showed that the sustainability status of organic farming in Bogor was categorized as Fairly Sustainable (58.57) on the ecological dimension. Still, the economic and social dimensions were moderately sustainable (52.09 and 53.70, respectively). Leverage attributes that very sensitive influenced the sustainability of organic agriculture are the availability of fertile land, the presence of organic product seeds, community consumption level for organic products, the market potential for organic products, average additional community income from organic product cultivation, and involvement of community institutions in organic farming development. The six attributes of levers must be prioritized for managers through the preparation and implementation of appropriate policies so that the sustainability of organic farming in Bogor, West Java, can be maintained
Resource Equivalency Analysis (REA): Implication environmental of groundwater in Kupang East Nusa Tenggara
Get PDFThis article discusses the environmental assessment caused by the commercial use of groundwater by the community as landowners. In the future, this practice must receive direction and responsibility from the government as policymakers to prevent and repair environmental damage, especially habitat damage and species in strengthening the principle of "paying for commercial groundwater" with the REA methodology to assess and compensate for environmental damage. This method, developed by the National Oceanographic and Atmospheric Administration (NOAA), uses the scale of remediation required to compensate for past, current and future damage. The compensation approaches are the services approach (or the resources approach) and the valuation approach (the value-to-value and value-to-cost approach). The results show that the change in residential land is 0.16%, or 25 ha. The total area of changed settlement/land built up has decreased the function of land which was originally secondary/logged-over dry land forest to become settlement/land built up. Furthermore, there was a decrease in secondary/logged-over dry land forest to open field of 0.03% or 3.1 ha, so that the total area of secondary/logged-over dry land forest decreased by 0.19% or 28.1 ha

Simulation of the impact of land use change on surface run-off in Karst Leang Lonrong Sub-Watershed
Get PDFEstimation of surface run-off in karst watersheds has not been widely carried out and the estimation method is generally developed for non-karst watersheds. This study aims to analyze the accuracy of estimation of river discharge at the outlet of the Karst Biringere Sub-watershed using the modified Soil Conservation Service Curve Number (SCS-CN) method and analyzed the impact of land use change on river discharge at the outlet of the Karst Biringere Sub-watershed. Modification of the SCS-CN method in estimating direct flow at the outlet of the Beringere Sub-watershed is influenced by the similarity of rainfall and direct flow fluctuation of river discharge. The modified SCS-CN method provides satisfactory direct flow estimation when rainfall with observed direct flow of river discharge forms a linear relationship with a strong correlation. Changes in land use with reduced forest cover into mining areas result in increased run-off and reduced storage, the larger the forest land becomes mining areas, the greater the increase in run-off and reduction in storage. Reclamation of the former mining area to be a forest reduces run-off and increases water storage
Local knowledge on bird species and socio-economic cultural and ecology functions of birds and their various disturbances in the rural ecosystem of the Cisokan watershed, West Java
Get PDFActually in the past, rural people of West Java had in-depth local knowledge on various species of birds. Nowadays, the local people\u27s knowledge on the bird species is being eroded due to the erosion of the local language and the bird population decreasing in the village ecosystem. The purpose of this study was to elucidate the knowledge of bird species, and the socio-economic, cultural, and ecological functions, and various disturbances to bird populations. The research was conducted in Bojongsalam and Sukaresmi Village, Rongga Sib-District, West Bandung, Cisokan Watershed, West Java.

The birds are classified by rural people based on body size, body feather color, type of habitat, and bird behavior. Bird species have an important role for socio-economic, cultural and ecological functions. Disturbance to bird populations, among others, due to the construction of the Cisokan hydropower project
Habitat and behavior of javan hawk-eagle (Nisaetus bartelsi) in SPTN 2 Majelengka Gunung Ciremai National Park, West Java
Get PDFKeberadaan Elang Jawa tergantung pada kondisi hutan di habitatnya. Jika hutan dataran rendah rusak, Elang Jawa akan terdorong ke hutan yang lebih tinggi; Hal ini dapat mempengaruhi perilaku Elang Jawa karena berkaitan dengan ketersediaan buruan di setiap tipe habitat. Penelitian ini bertujuan untuk menganalisis kondisi habitat dan perilaku Elang Jawa di Taman Nasional Gunung Ciremai, dengan menggunakan metode garis kotak-kotak dan focal animal sampling. Analisis habitat Elang Jawa menggunakan pendekatan analisis vegetasi dan tingkat penggunaan tipe habitat. Hasil penelitian menunjukkan bahwa Elang Jawa paling sering menggunakan tipe habitat hutan alam (85,38%) di situs Cipari dan hutan tanaman (83,14%) di situs Bantar agung. Jenis pohon yang dominan di hutan alam adalah benda (Castanopsis argentea; 20,02%) dan saninten (Artocarpus elasticus; 13,30%). Elang jawa memilih pohon untuk bersarang di pohon kedondong (Spondias pinnata) dan pohon pinus (Pinus merkusii ) di lembah-lembah di antara perbukitan dan dekat dengan sumber air atau sungai. Secara keseluruhan perilaku Elang Jawa yang ditemukan adalah beristirahat/bertengger, berburu, terbang, dan berinteraksi. Perilaku Elang Jawa yang paling banyak ditemukan adalah istirahat/bertengger (80,16%) dan interaksi (45,88%).The existence of the Javan hawk-eagle depends on the condition of the forest in its habitat. If the lowland forest is damaged, the Javan hawk-eagle will be pushed to the higher forest; This can affect the behavior of the Javan hawk-eagle because it is related to the availability of the game in each habitat type. This study aims to analyze the habitat conditions and behavior of the Javan hawk-eagle in Mount Ciremai National Park, using the checkered line method and focal animal sampling. Analysis of the Javan hawk-eagle habitat used a vegetation analysis approach and the level of use of habitat types. The results showed that the Javan hawk-eagle most often used natural forest habitat types (85.38%) at the Cipari site and plantation forests (83.14%) at the Bantar agung site. The dominant tree species in the natural forest are benda (Castanopsis argentea; 20.02%) and saninten (Artocarpus elasticus; 13.30%). Javan hawk-eagles choose trees to nest in kedondong trees (Spondias pinnata) and pine trees (Pinus merkusii ) in valleys between hills and close to water sources or rivers. Overall the behavior of the Javan hawk-eagle found is resting/perching, hunting, flying, and interacting. The most common behavior of Javan hawk-eagles found was resting/perching (80.16%) and interaction (45.88%)
Sustainable Finance in Financing Plantation Companies by Banking : Case Study of Palm Oil Corporation in Donggala Central Sulawesi Tengah
Get PDFKeuangan berkelanjutan adalah bentuk pembiayaan yang diberikan oleh Lembaga Jasa Keuangan (LJK) kepada debitur dengan mempertimbangkan aspek keberlanjutan kedalam keputusannya. Keuangan berkelanjutan belum menjadi perhatian serius dan orientasi LJK dalam pemberian kredit atau pembiayaan kepada debitur. Pembiayaan bermasalah mencerminkan adanya masalah dua pelaku ekonomi yang saling bertentangan (keagenan). Dengan melakukan analisis capaian keuangan berkelanjutan dan analisis hubungan keagenan ditemukan bahwa menilai kinerja keberlanjutan satu perusahaan (debitur) diperlukan kedetailan kriteria dan indikator keuangan berkelanjutan. Ketika menyalurkan kredit, perbankan tidak bisa hanya melihat dari aspek kesehatan keuangan dan kemapanan satu perusahaan. Sebab, perusahaan yang telah memiliki sertifikasi keberlanjutan dan memenuhi aspek administrasi, masih memiliki persoalan Lingkungan, Sosial, dan Tatakelola (LST) yang belum terselesaikan. Pelibatan para pihak dalam membangun “Informasi Hub” (forum koordinasi) terkait praktik LST yang berpusat di daerah menjadi penting.Sustainable finance is a form of financing provided by Financial Institutions (FIs) to debtors by considering sustainability aspects into their decisions. Sustainable finance has not become a serious concern and orientation of FIs in providing credit or financing to debtors. Problem financing reflects the problem of two conflicting economic actors (agency). By conducting an analysis of sustainable financial performance and agency relationship analysis, this study shows that assessing the sustainability performance of a company (the debtor) required detail criteria and indicators of sustainable finance. When disbursing credit, banks cannot only look at the financial health and stability of a company. This is because companies that already have sustainability certification and fulfill administrative aspects still have unresolved Environmental, Social and Governance (ESG) issues. The involvement of the parties in building an “Information Hub” (coordination forum) related to ESG practices centered in the regions is important
