Abstract

A management unit (MU) of a forest concession holder implementing the sustainable forest management (SFM) principles, could be involved in reducing Emmission from Reforestation and Forest Degradation (REDD+) and carbon trading project. The fact the strategic in implementing the REDD+ and carbon trading in MU level is still lack of pilot project and methodology. Therefore, some scenarios must be developed and tested to find out the best potential of carbon credit in MU level. The objectives of the research were: to calculate carbon credit in some SFM scenarios, to analyze of carbon trading project feasibility, and to determine carbon stock recovery period of logged over area (LOA). The result revealed that carbon stock and carbon credit of LOA was affected by timber cutting intensity. The 6th scenario with lowest annual allowable cutting (AAC) obtained greater carbon credit and profit coming from timber harvesting income and carbon trading. In other hand, this scenario has shortest duration of carbon stock recovery period (27 years) and shorter than its cutting cycle. In this case, the MU has to recalculate and to decrease its AAC to have highest benefits from carbon trading in the same cutting cycle period. It will provide double benefits from carbon trading, those are contribution in achieving the SFM purposes (production, ecology, social) and climate change mitigation.

Abstract

Human activities that alter land cover have destroyed natural ecosystems and caused conflict. In Indonesia, community-based forest management (CBFM) policies implemented by the government seek to empower communities, ameliorate forest conversion, and reduce environmental conflict. This article critically assesses contemporary CBFM policy in Indonesia by analyzing its history and outcomes through policy analysis. To systematically review previous literature on CBFM, this research uses the PRISMA method. It finds that communities are often able to manage forest areas sustainably through sociocultural systems that combine management customs and culture. Empowerment through CBFM policy therefore promises to promote community subsistence, equity, and security regarding forest management. However, granting total resource rights to communities can result in land conversion unless managerial safeguards are in place. Many studies find that the clarity of land boundaries, the consistency of regulation, and the partiality of land governance drive CBFM program success. To facilitate land governance for the successful implementation of Indonesian social forestry, communities need access rights, authority to manage forests, and sufficient knowledge transfer to participate in formal forest management. In contrast to previous iterations of CBFM in Indonesia, current social forestry policy acknowledges these governance needs and seeks to implement them.

Abstract

Effectiveness of Mercury Chloride (HgCl2) in Sterilization of Teak (Tectona grandis L.f.) In VitroThe main obstacle in obtaining sterile materials in in vitro cultures derived from meristems is high level of surface contamination caused by fungi and bacteria, which often results in explant death. The objective of this study was to obtain an appropriate mercury chloride (HgCl2) concentration for the sterilization of Tectona grandis nodes in in vitro culture. One cm long-sized nodes with 0.2 mm diameter were immersed in HgCl2at concentrations of 0, 100, 200 and 300 mg/L for 3 minutes. The results showed that the higher concentration of HgCl2was able to suppress the growth of fungi and bacteria and increased the percentage of aseptic explants. The best HgCl2concentration was 300 mg/L since it suppressed the growth of fungi and bacteria up to 100% and 75%, respectively, and produced the highest aseptic explants of 85% at 9 days after treatment. The small sized explants supported the sterilization process and reduced browning levels.Keywords: Browning, HgCl2, in vitro, sterilization, T. grandisABSTRAKKendala utama dalam mendapatkan material steril pada kultur in vitro yang berasal dari meristem adalah tingginya tingkat kontaminasi permukaan yang disebabkan oleh jamur dan bakteri, dan sering menyebabkan kematian eksplan. Tujuan penelitian ini adalah untuk memperoleh konsentrasi merkuri klorida (HgCl2) yang tepat untuk sterilisasi eksplan tunas samping tanaman jati (Tectona grandis) pada kultur in vitro. Tunas samping berukuran 1 cm dan diameter 0,2 mm direndam dalam HgCl2 pada konsentrasi 0, 100, 200 dan 300 mg/L selama 3 menit. Hasil penelitian menunjukkan bahwa penambahan konsentrasi HgCl2 yang semakin tinggi mampu menekan pertumbuhan jamur dan bakteri pada eksplan serta meningkatkan persentase eksplan aseptik. HgCl2 dengan konsentrasi 300 mg/L merupakan konsentrasi terbaik karena dapat menekan pertumbuhan jamur hingga 100% dan bakteri mencapai 75%, serta menghasilkan tingkat eksplan aseptik dan hidup tertinggi yaitu sebesar 85% pada 9 hari setelah perlakuan. Ukuran eksplan yang kecil mendukung proses sterilisasi dan mengurangi tingkat browning. Kata kunci: HgCl2,in vitro, pencoklatan jaringan, sterilisasi, T. grandis, Received: 02 November 2017                 Accepted: 14 December 2017                Published: 29 December 2017

Abstract

Cemara sumatra (Taxus sumatrana (Miquel) de Laub.) merupakan pohon penghasil taxane, zat aktif obat berkhasiat penyakit kanker. Perbanyakan bibit cemara sumatra bermasalah, karena sulitnya mendapatkan benih dan perkecambahan benihnya memerlukan perlakuan khusus. Teknik stek merupakan alternatif yang potensial untuk perbanyakan bibit jenis ini. Tujuan dari penelitian ini adalah untuk memperoleh informasi tentang pengaruh media terhadap pertumbuhan akar stek cemara sumatra. Sumber bahan stek berasal dari pohon dewasa yang tumbuh alami di Gunung Kerinci, Jambi. Media yang digunakan terdiri dari campuran serbuk kelapa : sekam padi (1:1 v/v), serbuk kelapa : sekam padi : tanah (1:1:1 v/v), dan serbuk kelapa : sekam padi (2:1 v/v).  Pengamatan terhadap perkembangan akar stek cemara sumatra dilakukan dengan menggunakan prosedur mikroteknik. Hasil penelitian menunjukkan bahwa dari semua variabel yang diamati, media hanya berpengaruh nyata terhadap kemampuan berakar stek.  Ketiga media yang dicobakan, campuran serbuk kelapa dan sekam padi pada perbandingan 2:1 v/v memberikan hasil terbaik untuk kemampuan berakar (66,7%).  Hasil dari pengamatan pertumbuhan dan perkembangan akar diketahui bahwa akar pada stek cemara sumatra berasal dari sel-sel meristem pada kambium

Abstract

Problem yang dihadapi di jalan sarad dalam pemanenan kayu adalah pemadatan tanah, erosi yang tinggi, menurunnya kesuburan tanah, miskinnya cendawan mikoriza dan kurangnya anakan. Untuk meningkatkan produktivitas hutan di jalan sarad, maka diperlukan upaya pemulihan antara lain dengan penanaman pengayaan intensif dan cara lain yang dapat untuk mengurangi laju erosi, meningkatkan kesuburan tanah di jalan sarad dengan menerapkan lubang resapan biopori (LRB) dan cross drain (Cd). Tujuan penelitian ini adalah untuk mendapatkan informasi tentang pemanfaatan LRB  dan Cd  dalam penanaman pengayaan intensif untuk peningkatan produktifitas jalan sarad di hutan alam bekas tebangan. Lokasi penelitian diberi ijin usaha pemanfaatan hasil hutan kayu hutan alam (IUPHHK-HA) pada hutan produksi Kalimantan Barat selama satu tahun. Rancangan penelitian adalah rancangan acak kelompok pola faktorial 2 x 2 dengan ulangan tiga kali. Faktor pertama yaitu LRB dan faktor kedua yaitu cross drain.  Hasil penelitian menunjukkan bahwa interaksi perlakuan LRB dan cross drain  memberi pengaruh yang nyata bagi pertumbuhan tinggi tanaman umur satu tahun Shorea leprosula dan Shorea parvifolia sedangkan untuk pertumbuhan diameternya tidak berpengaruh nyata. Perlakuan cross drain dapat meningkatkan serapan hara P, K, C organik di S. leprosula dan hanya serapan P dan C-organik di S. parvifolia.

Abstract

haracteristic of sandalwood germination is very slow,it is due to  seed coat thickness (seed coat dormancy). Boron is an important nutrient that is required to improve the seed germination and vigor. The aim of this research was to test the effectiveness of boron in various concentrations and period of soaking to speed up the seed germination. The experimental design of research was factorial in Completely Randomized Design (CRD). The results of this research showed that the initial treatment of sandalwood seed in boron soaking on 400 ppm concentration could accelerate the sandalwood seed germination one week earlier with 42% germination percentage while control was 34.6%. The optimal soaking of sandalwood seeds in boron  was 24 hours.
