Abstract

The objective of the study is to examine the effectiveness and feasibility of soil and water conservation techniques. The production of oil palm comprising the fresh fruit bunch, number of bunches, and average of bunch weight were recorded at every harvesting schedule. Tabular data were analyzed by logical comparison among the blocks as a result of application of bund terraces and silt-pit. Financial and sensitivity analysis of the effect of the techniques on FFB production were done. Bund terrace treatment was more effective (4.761 ton or 21.5%) in increasing FFB production than the silt-pit treatment (3.046 ton or 13.4%) when it is compared to that of the control block. The application of bund terraces and silt-pit also presents positive effects i.e. increases the average bunch weight and the number of bunch compared to that of the control. Furthermore, the financial analysis as well as sensitivity analysis shows that the bund terrace application is profitable and feasible (B/C = 3.06, IRR = 47%) while the silt pit treatment is profitable but not feasible.Keywords: Bund terrace, feasibility, production of FFB, silt-pit

Abstract

The support of the local government and all social levels in the community is the key to successful waste management systems. Waste is mainly produced by community households. Deficient treatment and disposal severely pollute the environment. Therefore, the community must have an active role in protecting the environment. Regulation is an important aspect of policies and programs for the implementation of the waste management system to ensure that lower regulation is in line with the higher policies made by the central government. The objective of the study was to review regional regulation on waste management, comparing them to the central regulation government of waste policy, and analyze the implementation of the waste management system in the region. Content analysis was used to analyze the waste management of regional government policy. The implementation of waste management systems was analyzed using primary data obtained through observation. The secondary data was obtained by classifying the waste generation in tabular data calculated from the average of waste production by household per capita to the number of the population each subdistrict. The result indicated that the Regulation of Tapin District No. 6 of 2015 on the waste management system is in line with the central government waste policy. The implementation of waste management systems had not been carried out effectively by the regional government. The district generated solid waste at 93.3 tons each day and can only manage 27.21% in 4 subdistricts of urban settlement areas. The solid waste generation can be classified into five classes. Most are in the low and very low waste generation class. The very high generation class was in subdistricts, which have the highest population density in the region.

Abstract

Forest degradation has been important in the context of global issues since it contributes to the global climate change significanly.  Forest degradation of tropical rain forest area reduces global biological resources and has impact on occurence of poverty in community.  It also increases forest fragmentation and decreases forest connectivity as wildlife habitat.  To improve the connectivity, landscape restoration approach is used.  This paper describes the forest landscape restoration priority index to decide where the site gets restoration priority.  Restoration index is constructed by four factors indices that are index of forest degradation, forest connectivity, forest fragmentation, and socio economic of forest communities. Batang Toru forest landscape was getting pressure during the period 1989-2013.  Forest landscape fragmentation degree increased in the period 1989-2013, while the degree of connectivity tends to increase.  Forest connectivity index effects the restoration index more than other.  It implies that connectivity of Batang Toru forest landscape needs to be maintained and enhanced. It will provide proper habitat and reduce loss of biodiversity. Restoration index classifies Batang Toru forest landscape into low, medium and high priority for restoration. Sub-watershed of Sarula has high restoration index value so that it must be restored firstly.

Abstract

Penerapan model USLE pada beberapa Daerah Aliran Sungai (DAS) di Indonesia menunjukkan keragaman proses yang mempengaruhi terjadinya erosi tanah. Integrasi model USLE ke dalam Sistem Informasi Geografis (SIG) mampu memberikan gambaran spasial dari sebaran kelas erosi tanah. Penelitian ini bertujuan untuk memprediksi besarnya erosi tanah pada berbagai tutupan lahan di sub DAS Ciesek dengan mengintegrasikan model USLE ke dalam SIG. Pengambilan sampel tanah utuh dan terganggu dilakukan berdasarkan SPT, disertai pengamatan sifat fisik tanah di lapangan. Prediksi erosi tanah dilakukan menggunakan menu raster calculator dengan input data berbasis raster yang memiliki resolusi spasial tertentu. Analisis sebaran kelas erosi pada berbagai jenis tutupan lahan dan kelas lereng dilakukan dengan metode tabulasi silang. Hasil penelitian menunjukkan bahwa kelas erosi tanah sangat rendah dominan di lokasi penelitian yaitu pada area dengan tutupan lahan hutan. Erosi tanah prediksi tertinggi dihasilkan dari tutupan lahan terbuka, diikuti oleh lahan tegalan, dan kebun campuran
