Produktifitas Lebah Trigona SP. Pada Berbagai Teknik Budidaya Di Desa Nayagati Kecamatan Leuwidamar Kabupaten Lebak

Non-Timber Forest Products (HHBK) have been used by communities around the forest. Apart from being easy to obtain and not requiring complicated technology to get it, it also has high economic value. It is believed that the existence of NTFPs is most closely related to the interests of the community, especially the people living around the forest, in fulfilling their daily needs. One of the NTFPs products is honey bee which has high economic and utility value. This study aims to determine the bee cultivation technique of Trigona sp. which produces the highest hive weight and bee product. This research is located in Bulakan Village, Nayagati Village, Leuwidamar District, Lebak Regency. The research was conducted for 3 (three) months from August to December 2019. The research method was by observing the weight of the hive and yield of bee products, and analyzed descriptively. The results showed that the bee cultivation technique that produced the highest productivity in terms of hive weight yield, honey, propolis and brood bee was the cage technique, and the factors that caused differences in productivity were the source of feed and the presence of predators. In the cultivation of bees Trigona sp. The source of feed is very important, besides the need for monitoring every day to avoid predators

Produktivitas dan Rendemen Industri Penggergajian Kayu di Kecamatan Cigudeg Kabupaten Bogor

Proses penggergajian merupakan proses yang awal dalam merubah kayu, dari yang masih berbentuk log menjadi kayu gergajian yang berbentuk balok, papan, tiang, bantalan dan betuk sortimen lainya. Untuk kegiatan merubah log menjadi kayu gergajian, ada beberapa hal yang perlu diperhatikan agar dapat semaksimal mungkin memberikan keuntungan yang signifikan, yaitu dengan memberikan efektivitas terhadap produktivitas dan rendemen penggergajian. Penelitian ini bertujuan untuk mengetahui rata-rata produktivitas per jam per mesin dan rata-rata rendemen industri penggergajian kayu tersebut. Metode penelitian yang digunakan adalah metode kuantitatif dimana data produksi dan rendemen dilakukan pengukuran langsung serta wawancara dengan pemilik industri dan operator penggergajian. Hasil penelitian menunjukan produktivitas industri penggergajian di Cigudeg sebesar 0.87 m3/mesin/jam dengan rendemen penggergajian 56.52 %

Pemanfaatan Limbah Penggergajian Kayu Sengon (Paraserianthes Falcataria) Menjadi Papan Serat

Fiberboard can be made from a variety of berligno-cellulose fiber materials. One of the berligno-sesulose fiber materials is Sengon wood which is a waste of sawmills. Efforts to use sengon wood waste can be used for high density fiberboard. In this study we want to see the quality of sengon wood fiber board with TRF adhesive (Tanin Resolsinol Formaldehyde). The sengon wood fiber board was tested according to the JIS A-5905-2003 standard. The parameters tested were the physical-mechanical quality of the fiberboard, namely density, moisture content, water absorption, thickness development, elastic modulus, fracture modulus and internal adhesive strength. TRF is applied in three levels, namely: 0%, 6% and 8%. The results showed that the physical-mechanical quality that met the JIS A-5905-2003 standard was density (0.935 - 1.204 g / cm3), moisture content (9.840 - 12.2%), modulus of elasticity (313.55 - 355.53 kg / cm2), broken modulus (36,672 - 39,341 kg / cm2) and internal adhesion strength (4,244 - 4,371 kg / cm3). While the nature of water absorption (65,875 - 79,856%) and the development of thickness (27,665 - 39,295%) did not meet the JIS A-5905-2003 standard, at all TRF levels
