Abstract

This paper deals with the design and performance test of pyrolysis burning stoves that produce energy for cooking and biochar. The stove consists of two section chambers, namelycombustion chamber that produces activation heat for pyrolysis process and energy for cooking, andpyrolysis chamber that produces biochar and volatile matter (syngas and tar in gas form). Volatile matter product was introduced to the combustion chamber in addition to the biomass there and replaces biomass fuel gradually to produce energy for cooking and keeping the continuous pyrolysis process (autothermal). Methode used for performance test: direct observations/measurements and Water Boilling Test (WBT). Result of performance test: the autothermal process was going well until resulting a 100% biochar for most of the biomass used. Thermal efficiency of the stove was 11.3% (before pyrolysis) and 14.72% (after pyrolysis), excluding heat to produce biochar. Time needed to boil a 5 L water was 12 minutes before pyrolysis and 6 minutes after pyrolysis. Output power ranges from 9.60 kW to 23.16 kW. The maximum temperature reached 868 °C at the pan and 860oC in combustion chamber.Input biomass capacity depending on the type of feedstock ranging from 1200 - 3000 g/process, resulting in 507-900 g biochar/process, to give biochar ratio to raw materials from 23.0% to 44.8%. All maximum conditions occurs when volatilematters produced from pyrolysis process were burned, which showed that burning volatile matters is better than burning solid biomass directly.The amount of biochar produced by this stove was three times higher compared to anila stove, with less of smoke during the biochar production.

Abstract

Indonesia adalah salah satu negara dengan perubahan tutupan lahan yang dinamis karena sumber perekonomian negara yang bersumber pada pengelolaan sumber daya berbasis lahan. Di sisi lain, pengelolaan tersebut berdampak negatif seperti konflik sosial dan kerusakan lingkungan. Penelitian ini mengamati pola perubahan tutupan lahan dan mengeksplorasi faktor pendorong penyebab perubahan tersebut pada periode 1990-2019 di Pulau Bengkalis, Indonesia untuk memantau dan menghasilkan informasi yang dapat digunakan sebagai dasar dalam meminimalkan perubahan tutupan lahan yang tidak terkendali. Penelitian ini dilakukan dengan mempelajari laporan dan penelitian sebelumnya, observasi, dan melaksanakan fokus grup diskusi dan wawancara mendalam. Penelitian ini menggunakan GIS dalam analisis perubahan tutupan dan penggunaan lahan multiwaktu. Hasil penelitian menunjukkan bahwa tutupan hutan alam menurun tajam sejak tahun 1990. Setelah tahun 2000, area kebun campuran lebih luas dibandingkan dengan tutupan hutan alam. Luas areal perkebunan kelapa sawit dan hutan tanaman juga mulai meningkat. Program transmigrasi telah memicu pembukaan lahan besar-besaran di Pulau Bengkalis. Pembukaan lahan oleh transmigran dan krisis ekonomi mendorong pembukaan lahan yang lebih besar oleh transmigran spontan.

Abstract

Degradation of peatland ecosystem on community land is controlled by the article 32 A paragraph (3) of Government Regulation Number 57 of 2016 concerning Amendments to Government Regulation Number 71 of 2014 concerning Protection and Management of Peatland Ecosystems which provide explicit direction that the restoration of peatland ecosystem forest and functions owned by the community or indigenous peoples is their responsibility. To assist the community to have countermeasures actions for peatland ecosystem degradation on the community land, the government has implemented the Peatland Self-supporting Villages (Desa Mandiri Peduli Gambut) program since 2016 in several provinces including Central Kalimantan Province. This study aims to: (1) analyze the current policy for controlling degradation to the peatland ecosystem if it applied to community land, and (2) Analyze the implementation of the policy for controlling degradation to the peatland ecosystem through the implementation of the Peatland Self-supporting Villages in the ex PLG area of Central Kalimantan Province by assessing the sustainability and implementation strategy of the program. The results of the study are: (1) The peatland ecosystem destruction control policy that has been applied to the licensed land can be applied to community land as long as they has sufficient capacity (2) the sustainability assessment of the implementation of the Peatland Self-supporting Villages program in the ex-PLG Area of ​​Central Kalimantan Province is included in the “moderate” category with an index value of 68.54, while the main strategy for proper implementation is by conducting exposure meetings of the Community Work Plan (Rencana Kerja Masyarakat, RKM) document to the relevant agencies and collaborating through programs that are in accordance with their duties.

Abstract

Indonesia has a peat area of around 14.91 million hectares and has become the fourth largest owner of peat reserves in the world after Canada, Russia and the United States. Peatlands play a major role as carbon sinks and maintain a hydrological system. The destructive and oxidized characteristics of peat make the International and Indonesian Governments pay high attention to the management and protection of peat ecosystems. Through the Advocacy Coalition Framework (ACF) approach, this study found that there are a variety of actors and stakeholders who influence the dynamics of peat management and cultivation policy formulation in Indonesia. The actors and stakeholders formed a coalition by carrying out the logic of their respective belief systems, namely: Coalition A which has a belief system that peat land is a potential resource developed for cultivation and Coalition B which has a belief system that views peat ecosystems as vulnerable ecosystems that must be protected and rehabilitated. The results of this study are expected to be able to provide recommendations needed in realizing sustainable management of peat ecosystems.

Abstract

Penelitian ini bertujuan untuk merancang sebuah rezim hak kepemilikan tanah dan hak terhadap akses pengelolaan yang mendukung lembaga konservasi penyu yang efektif. Penelitian ini dilakukan di Ujung Genteng - Pangumbahan, Kabupaten Sukabumi sebagai daerah pesisir yang terkait dengan upaya konservasi penyu mulai dari bulan Desember 2009 sampai Maret 2012. Data yang dikumpulkan dianalisis dengan menggunakan metode analisis spasial dan analisis deskriptif. Hasil penelitian dengan menggunakan analisis spasial pada wilayah seluas 1.334,70 hektar menunjukkan bahwa antara tahun 2001 - 2010, luas lahan pertanian meningkat sebesar 31% dan daerah pengembangannya (28,78%) memanjang ke arah pantai. Pola perubahan penggunaan lahan dipicu oleh transisi dari tanah terlantar menjadi pemukiman dan pembangunan fasilitas wisata bahari. Berdasarkan dinamika perubahan penggunaan sumber daya lahan sangat diperlukan perubahan kelembagaan untuk menjamin kepastian pemanfaatan sumberdaya lahan di wilayah pesisir sejalan dengan tujuan konservasi penyu. Pemerintah pusat mendelegasikan otoritas kewenangannya ke tingkat desa dan pemerintah desa menjadi pemilik dan pengelola di instansi yang bersangkutan Title: Property Rights And Access Rights of Land For Turtle Conservation Institutions EffectivenessThis research aims to design a regime of rights ownership of land and management access rights that supports the institution of effective sea turtle conservation.

Abstract

Kondisi sektor kehutanan Indonesia selama tiga-empat dasa warsa terakhir dapat dilihat dari perkembangan bidang pengusahaan hutan yang semakin menurun. Perkembangan yang kurang menggembirakan ini tidak saja disebabkan lemahnya tata kelola perusahaan namun juga tata kelola pemerintahan. Tujuan penelitian ini adalah : Untuk mengetahui gambaran pelaksanaan prinsip-prinsip tata kelola yang baik (GCG) pada perusahaan-perusahaan bidang kehutanan dan menemukan berbagai aspek kebijakan yang dapat mendukung penguatan GCG bidang kehutanan. Metode yang digunakan adalah survei dan wawancara pada pemegang 6 (enam) ijin usaha pemanfaatan hasil hutan dengan menggunakan kuesioner terstruktur. Perusahaan dipilih secara purposive dari perusahaan yang aktif beroperasi. Peraturan dan implementasinya dikaji melalui anlisis isi, anlisis diskursus dan wawancara dengan Dinas Kehutanan. asosiasi pengusaha, Kementerian Kehutanan dan lembaga otoritas yang terkait dengan tata kelola perusahaan. Penelitian lapangan dilakukan di propinsi Riau dan Sumatera Selatan pada tahun 2010. Hasil penelitian menunjukkan bahwa belum satuoun perusahaan kehutanan yang terdaftar di pasar modal. BUMN dan perusahaan besar sudah melaksanakan GCG berdasarkan pedoman sedangkan perusahaan kecil belum menerapkan GCG. Dari hasil kajian disarankan agar pemerintah dan para pihak terkait perlu menyusun kerangka kerja dan rencana penerapan GCG pada perusahaan - perusahaan kehutanan. Dalam penetapan kebijakan, program maupun rencana kehutanan disarankan agar tidak hanya memperhatikan kesesuaiannya dengan peraturan - perundangan melainkan harus memperhatikan efektivitas dan efisiensi pelayanan.
