Abstract

Abstrak DAS Citarum mengalami perubahan struktur lingkungan yang tinggi yang berakibat pada penurunan kualitas lingkungan, sehingga diperlukan gambaran mendetail mengenai kondisi perubahan lahan vegetasi di DAS Citarum. Tujuan dari penelitian ini untuk mengetahui proses perubahan luasan lahan vegetasi di DAS Citarum, Bandung, Jawa Barat. Penelitian ini menggunakan data penginderaan jauh dengan pendekatan kuantitatif. Pemetaan perubahan penutupan vegetasi di DAS Citarum menggunakan data citra Landsat multitemporal dengan perangkat lunak QGIS. Pada pelaksanaan penelitian ini, beberapa tahapan yang dilakukan, diantaranya pengolahan awal citra satelit (pre-processing), pengolahan citra digital (image processing), verifikasi data citra (NDVI), dan analisis perubahan penutupan lahan. Hasil studi menunjukkan bahwa terjadi penurunan luasan lahan vegetasi seluas 35% pada tahun 1989 – 2019 dengan rata-rata penyusutan luas lahan sebesar 0.64% setiap tahunnya dan penyusutan terbesar pada tahun 2006. Penyusutan lahan cenderung terjadi pada wilayah yang berbatasan dengan Kota Bandung, yang diperkirakan sebagai bagian dari pengembangan wilayah kota kedaerah sekitarnya dan hasil menunjukkan wilayah yang mengalami penyusutan terbesar merupakan kecamatan dengan luas wilayah relatif kecil dibandingkan dengan wilayah kecamatan lainnya seperti Cipatat (74%) dan Batujajar (83%). Meski demikian, selama periode tahun 1989 – 2019, beberapa kecamatan menunjukkan peningkatan luas lahan bervegetasi seperti Kecamatan Bojongsoang, Slawi, dan Tanjungsari. Kata kunci: Citra Satelit, Landsat, Penyusutan Lahan. Abstract The Citarum watershed undergoes a significant change in environmental structure, which results in a decrease in environmental quality, so a detailed description of the conditions of land change in vegetation in the Citarum watershed is needed. The main objective of this study: the process of changing the area of vegetation in the Citarum watershed, Bandung, West Java. This study uses remote sensing data with a quantitative approach. Mapping of land cover changes in the Citarum watershed uses multitemporal Landsat imagery with QGIS software. Several steps were carried out, including pre-processing, image processing, NDVI, and land cover change analysis. The study results show a decrease in the area of vegetation area of 35% in 1989 - 2019, with an average shrinkage of the land area of 0.64% annually and the most extensive shrinkage in 2006. Land shrinkage tends to occur in areas bordering Bandung City, which is estimated as part of the city's development to the surrounding area. The most extensive shrinkage areas are the districts with relatively small areas compared to other sub-districts such as Cipatat (74%) and Batujajar (83%). However, during the period 1989 - 2019, several sub-districts showed an increase in vegetated land areas, such as Bojongsoang, Slawi, and Tanjungsari Districts.

Abstract. Community dedication to public understanding of the agroforestry system aims to increase awareness and participation in the Kertasari Subdistrict in practicing the agroforestry system without coercion or pressure. The method used is observation through interviews and discussions to share the knowledge. The activities stages were carried out, including population determination, issue screening, analysis, and Focus Group Discussion (FGD). FGD was conducted to provide recommendations to increase public understanding of the agroforestry system, which is a solution to overcome critical land problems in the Upper Citarum watershed. The results show that more than 70% of farmers understand the purpose, crop plants that become commodities, and the benefits of agroforestry systems for the environment. However, less than 20% of farmers understand the benefits of agroforestry systems on income. In its implementation, farmers experience several obstacles related to land ownership, commodities, and post-harvest management. Recommendations can be applied to optimize the agroforestry system, including maximizing extension activities, mentoring, and collaboration from relevant stakeholders. It can be concluded that farmers in the Kertasari Subdistrict have applied the agroforestry system, even though they have limited knowledge, so they need motivation in their implementation.Keywords: Agroforestry, Focus Group Discussion, KertasariAbstrak.

Abstract

Changes from agricultural land to non-agricultural land are continuously occurring, especially in areas adjacent to cities. Land changes from agricultural to non-agricultural land will eliminate crops’ hydrological function, impacting rivers, including the Cirasea River. Besides, changes in agricultural land have an impact on the resulting agricultural productivity and income. This study’s main objective is to determine land area changes, productivity, and farmers’ income in 2011 - 2018 in the Cirasea watershed. A literature study was applied to this study. Secondary data were obtained from the Central Bureau of Statistics of Ciparay, Ibun, Kertasari, Majalaya, Pacet, and Paseh Districts, Bandung Regency in Cirasea River Upstream. The study results showed an increase in land area, productivity, and agricultural income for vegetables (75%, 50%, and 68%, respectively) and rice field (16%, 0.32%, and 0.32%). In addition, there was a decrease in land area followed by a decrease in agricultural productivity and income for fruit commodities (-88%, -35%, -33%) and plantations (-97%, -1%, -1%). For eight years, farmers have relied on their income from vegetable commodities in Cirasea Watershed.

Abstract

Indonesia sebagai salah satu negara berkembang juga diwajibkan untuk mengurangi sumber emisi gas seperti CO2, emisi pabrik, transportasi dan penggunaan energi fosil pada pembangunannya. Salah satu usaha yang dilakukan dalam menghadapi meningkatnya gas rumah kaca adalah meningkatkan kemampuan vegetasi baik hutan, kebun dan tanaman lain dalam mengikat CO2. Karbon yang tersimpan pada hutan tanaman baik yang terdapat pada bagian atas dan bagian bawah merupakan suatu cadangan sumber daya alam yang dapat digunakan bagi keberlangsungan hidup terutama dalam kondisi krisis lingkungan global yang terjadi saat ini. Penelitian ini didasarkan pada pendugaan cadangan karbon pada biomassa, nekromassa Acacia crassicarpa dan tanah gambut hutan tanaman industri di Kabupaten Bengkalis Provinsi Riau. Tujuan penelitian ini adalah untuk menghitung cadangan karbon (carbon stock) pada biomassa, nekromassa Acacia crassicarpa dan tanah gambut hutan tanaman industri di Kabupaten Bengkalis Provinsi Riau dan mengestimasi pembangunan hutan tanaman industri yang berkelanjutan pada lahan gambut di Kabupaten Bengkalis Provinsi Riau. Metode yang digunakan pada penelitian ini melalui pendekatan metode dominant quantitative-less dominant qualitative dan metode pengumpulan data pada penelitian ini didominasi menggunakan metode survai. Hasil penelitian menunjukan bahwa besarnya cadangan karbon pada biomassa 2.808.363,28 t c/ha, nekromassa 2004, 437 t c/ha dan tanah gambut sebesar 560.938,5 t c/ha. Keberadaan hutan tanaman industri dapat memberikan jasa ekologis berupa cadangan karbon apabila dilakukan pengelolaan yang tepat, khususnya memiliki peluang simpanan pada nekromassa dan tanah gambut.
