Judul: Studi Perbandingan Pengelolaan Hutan Rakyat di Kecamatan Sumpiuh, Kabupaten Banyumas dan di Kecamatan Kawali, Kabupaten Ciamis
Abstrak: Pengelolaan hutan rakyat terdiri dari empat subsistem yang membangun di dalamnya, yaitu subsistem produksi, pengolahan, pemasaran dan kelembagaan. Setiap subsistem di suatu wilayah dapat memiliki persamaan maupun perbedaan, tergantung pihak-pihak yang terlibat di dalamnya. Penelitian ini bertujuan untuk mendeskripsikan pengelolaan hutan rakyat di Kecamatan Sumpiuh, Kabupaten Banyumas dan di Kecamatan Kawali, Kabupaten Ciamis, mengidentifikasi persamaan dan perbedaan pengelolaan hutan rakyat, dan menjelaskan pembelajaran dari pengalaman praktik pengelolaan hutan rakyat. Metode yang digunakan berupa komparasi secara deskriptif dengan menggunakan data kualitatif dan kuantitatif. Sampel yang dipilih sebanyak 68 sampel menggunakan metode purposive sampling. Karakteristik petani hutan rakyat di kedua lokasi penelitian didominasi oleh usia produktif, tingkat pendidikan rendah, pekerjaan utama didominasi oleh penderes di Banyumas dan petani di Ciamis, pengalaman bertani kategori lama, luas kepemilikan lahan terbilang sempit, pemeliharaan tanaman dan pengolahan kayu oleh petani yang masih sederhana. Terdapat industri penggergajian di kedua lokasi penelitian dan industri mebel di Banyumas, industri penggergajian yang mencari bahan baku langsung ke petani, dan terdapat kelompok tani dengan fokus kegiatan berbeda. Pembelajarannya yaitu masyarakat mengusahakan jenis tanaman selain kayu yang memiliki nilai ekonomi tinggi, dan keberadaan industri kayu skala besar dibutuhkan di dekat hutan rakyat., Community forest management consists of four subsystems that are built within it, namely production, processing, marketing and institutional subsystems. Each subsystem in an area can have similarities or differences, depending on the parties involved in it. This study aims to describe community forest management in Sumpiuh District, Banyumas Regency and in Kawali District, Ciamis Regency, identify similarities and differences in community forest management, and explain lessons learned from practical experience in community forest management. The method used is a descriptive comparison using qualitative and quantitative data. 68 samples were selected using purposive sampling method. Characteristics of smallholder forest farmers in the two study locations were dominated by productive age, low education level, the main occupation was dominated by tapers in Banyumas and farmers in Ciamis, old category of farming experience, relatively narrow landholding area, plant maintenance and wood processing by farmers are still simple. There is a sawmill industry in both research locations and furniture in Banyumas, a sawmill industry that seeks raw materials directly from farmers, and there are farmer groups with different activity focuses. The lesson learned is that the community cultivates types of plants other than wood that have high economic value, and the presence of large-scale timber industries is needed near community forests.

Judul: Sistem Pengelolaan Hutan Rakyat Jenis Sengon (Paraserianthes falcataria (L) Nielsen) di Desa Burat, Kecamatan Kepil, Kabupaten Wonosobo
Abstrak: Forest is one of renewable resources. The goal of forest management and forest utilization is to increase society welfare without aside it’s sustainable aspect. In fact, there are several things that supposed to be maximal on forest management, especially in community forest. Community forest has simple management it also has diversity on geographical place and treatment from its land holder. With several ways on developing community forest and also more intensive community forest management with sustainable ways together with support capability from community forest resources potency, exertion activity , environmental dynamics and the other factors are expected to form community forest as a certain business strategic that capable to maintain sustainable production and utilization that also put forest sustainable as priority. This research main objective is to learn community forest management and tabulate systemization of sustainable production planning of community forest at Burat Village, Kepil Sub-District, Wonosobo Regency, Central Java. Data taken in this research includes primary data from direct interview to land holder as producer, merchant, craftsman industry and timber industry. Secondary data taken from Forestry Department of Wonosobo Regency, Kepil Sub-District office, Burat Village office and internet browsing. Analysis method that use in this research are qualitative analysis for secondary data based on interview result and quantitative analysis for sengon species potency as primary data that taken based on simple sampling technique. Burat Village community forest has a simple management; it is proven by phases of utilization activity including planting, cultivation, harvesting, and marketing that haven’t follow the same pattern of management activity. This is occurring by ineffective management information that implement to all land holders at Burat community forest. There’s also misdistribution on supporting factors such as facility and infrastructure in Burat Village community forest. Institutional system and policy also cannot deliver utmost support for development of Burat Village sengon community forest management. Rotation on every sub-village is determined by range of rotation on existing condition; there are two different rotations which is 6 years rotation (Geger Jeruk and Krungsung sub village) and 7 years rotation (Burat, Kalibarong, Kalinongko, Kaliwang and Krajan sub village). Sustainability concept for every sub village that implemented 6 years rotation is range 1069 – 1118 trees/ha that can be harvest or replant, 3 years period 535 – 559 trees/ha, 1 year period 1178 – 186 trees/ha, 6 months period 89 – 93 trees/ha and for 3 months period 45 – 47 trees/ha. Sustainability concept for every sub village that implemented 7 years rotation is range 226 – 893 trees/ha that can be harvest or replant, 3 years period 97 – 383 trees/ha, 1 year period 32 – 128 trees/ha, 6 months period 16 – 64 trees/ha and for 3 months period 8 – 32 trees/ha.

Judul: Hydroxyapatite-Chitosan Composite Coating on Stainless Steel 316 to Improve Corrosion Resistance
Abstrak: Metals that were used in bone implantation should have good corrosion resistance that were not easily corroded when implanted into the body. Metal corrosion resistance of stainless steel 316 can be enhanced through the metal coating by hydroxyapatite-chitosan composite with composition ratio of hydroxyapatite (gram) and chitosan 3% (mL) 0.2:0, 0.2:0.1, 0.2:0.5, 0.2:1.0, and 0.2:1.5. Besides improving the corrosion resistance of metal, the presence of chitosan also maintain the position of hydroxyapatite on metal surfaces. Corrosion resistance increases with increasing amount of chitosan added and the best composition of hydroxyapatite-chitosan composite was 0.2:1.0.
