Judul: Perencanaan Pertanian Konservasi pada Pengelolaan Lahan Tradisional di Kecamatan Amarasi Barat, Nusa Tenggara Timur
Abstrak: Laju pertumbuhan penduduk menyebabkan peningkatan kebutuhan dan untuk memenuhinya, beberapa sistem pengelolaan diterapkan termasuk pengelolaan tradisional. Sistem pengelolaan lahan tradisional untuk kegiatan pertanian dilakukan sepanjang tahun dan diolah terus menerus, jika tidak disertai dengan kaidah-kaidah konservasi tanah yang memadai, akan memicu terjadinya kerusakan tanah akibat erosi yang dapat mengakibatkan lahan-lahan menjadi kritis. Penelitian ini bertujuan untuk menganalisis keramahan lingkungan dari sistem pengelolaan lahan tradisional berdasarkan analisis prediksi erosi dan menganalisis, merencanakan, dan menentukan perencanaan penggunaan lahan yang tepat atau tindakan konservasi untuk meningkatkan keramahan lingkungannya. Penelitian lapang dan laboratorium dilaksanakan pada bulan Maret-Agustus 2019. Lokasi penelitian terdapat ditiga desa dengan sistem pengelolaan tradisional yang berbeda desa Teunbaun sistem mamar, desa Niukbaun sistem tebas bakar dan desa Merbaun sistem wanaternak. Metode penelitian yang digunakan untuk prediksi erosi yaitu model persamaan Universal soil Loss Equation (USLE) oleh Wischmeier dan Smith (1978), kemudian untuk menghitung nilai laju erosi yang masih dapat ditoleransikan (TSL) menggunakan persamaan yang dikemukakan oleh Hammer (1981), serta terdapat tahapan tindakan alternatif KTA atau alternatif pengelolaan lahan pada penelitian ini, ditentukan dengan memodifikasi nilai penutupan lahan (C) dan nilai pengelolan lahan atau konservasi (P), dengan memperhatikan hasil perbandingan antara nilai besaran erosi (A) dan nilai erosi dapat ditoleransi (TSL). Hasil penelitian menunjukan lahan dengan sistem pengelolaan yang sedang dikelola tidak ramah lingkungan yang ditandai dengan hasil prediksi erosi yaitu nilai besaran erosi (A) lebih besar dibandingkan nilai erosi dapat ditoleransi (TSL). Nilai A tertinggi pada lahan tebas bakar, kemudian lahan wanaternak dan terakhir pada sitem mamar. Hasil prediksi erosi menunjukan pentingnya tindakan konservasi untuk meminimalisir nilai besaran erosi dari tiap lahan yang diamati dengan menentukan nilai penutupan lahan dan pengelolaan lahan (CP) yang tepat. terdapat beberapa skenario, dan didapatkan skenario ideal sebagai remokendasi yang dapat menurunkan nilai besaran erosi dari nilai erosi dapat ditoleransi. Skenario ideal menunjukan nilai C dan P yang direkomendasikan dapat menurunkan nilai besaran erosi sehingga lebih kecil dibandingkan nilai erosi dapat ditoleransi. Tindakan konservasi yang perlu diterapkan antara lain teras gulud. Pengelolaan tanaman yang dapat dilakukan adalah meningkatkan kerapatan tajuk tanaman pada beberapa lahan dengan penggunaan lahan agroforestri, hingga merotasi tanaman disertai mulsa., High population growth causes an increase in demand and to fulfill it, several management systems have been implemented including traditional management. The traditional land management system for agricultural activities is carried out throughout the year and processed continuously, if not accompanied by adequate soil conservation principles, it will lead to soil damage due to erosion which can result in critical lands. This research aimed to analyze the environmental friendly of traditional land management systems based on soil erosion parameter and to analyze, plan, and determine the appropriate land use management or conservation measure for improving its environmental friendliness. Field and laboratory research were conducted from March to August 2019. Research sites were in three villages with different traditional management systems, Teunbaun village, Mamar system, Niukbaun village, slash and burn system, and Merbaun village silvopasture. Research method applied for erosion prediction was Universal Soil Loss Equation (USLE) equation model by Wischmeier and Smith (1978). Calculation the value of tolerable soil loss (TSL) was using the equation

Judul: Pendugaan Tingkat Bahaya Erosi Untuk Optimalisasi Penggunaan Lahan Studi Kasus Di Desa Lamajang, Kecamatan Pangalengan, Kabupaten Bandung, Das Citarum Hulu
Abstrak: Erosion is a major cause of land degradation that lead to critical land formation. Erosion is influenced by several factor, such as : climate, soil erodibility, topograhy, land use, and conservation techniques. Among those five factors the first three factors are factors difficult to change. Therefore, erosion prevention efforts to reduce land degradation generaly focused on the regulation of land use and conservation techniques (land use optimization). Land use optimization was done by allocating any land use for a proper land use in such a way that land degradation can be prevented, i.e land use that produce erosion less than tolerable erosion. Therefore, prediction of actual and potential soil erosion as well as tolerable soil erosion level to determine erosion hazard is necessary. The method used is Universal Soil Loss Equation (USLE) which is a common method used to calculate the erosion rate. The advantages of this method are easy to apply and compatible in areas which have a rainfall and surface runoff as the main factors that causing erosion. The aim of this research is to produce a new scheme of land use based on the level of erosion hazard in order to obtain a sustainable agriculture (optimal allocation of land use) in the Lamajang Village, Sub-district Pangalengan, District of Bandung, West Java. This research includes: field observations, determination of rainfall erosivity, soil erodibility, topography, land use, land conservation techniques, and erosion hazard index. Based on data evaluation and interpretation, 7 land units are found in studied area with erosion rates ranging from low to very high. Land units with erosion hazard greater than tolerance level require land optimization. Optimization of land use activities should include the aspects of erosion, social, cultural, and economic, so make it easy to be accepted and applied for local communities The results of this study showed that erosion hazard in the studied area is very high due to high rainfall and steep slopes. Since actual soil erosion higher than tolerable level it is necessary to optimize the land use. The method of land use optimization suggested for the study area is “Good Terrace”. On areas with slope steepness higher than 60% Agroforestry system is proposed. This Agroforestry system compose of pine as high canopy, coffe or quinine as medium canopy, and chili or tomato as lower canopy (basal cover), that are planted follow contour.
