Judul: Pemanfaatan SIG dalam Pemetaan Potensi Merbau di Areal IUPHHK-HA PT. Wapoga Mutiara Timber Unit II Papua
Abstrak: Merbau is one of famous timber trade. Merbau included in the Fabaceae family which spread from Sumatera to Papua. Research on merbau potential mapping use geographical information systems (GIS) need to be conducted to obtain the data about potential merbau. This research is purposed to explain the most accuratest spatial interpolation method between inverse distance weight (IDW) method toward the kriging method, to explain the most accuratest number of variables, in order to create a map of merbau potential at IUPHHK-HA PT. Wapoga Mutiara Timber 2nd unit (PT. WMT-II) area. Merbau potential value in 2012 is calculated based on data of IHMB at PT. WMT-II. Unrepresented of merbau potential in IHMB plot was estimated by spatial interpolation. Potential map of merbau level of trees and poles are able to use IDW method with 4-classes that is very low, low, medium, and high. The combination of PG, PN, and PV variables with IDW is the best method to create potential map of merbau for each level. Potential map of merbau consist of 2 type map that explain merbau potential level of poles and tree at IUPHHK-HA PT. WMT-II area. Generally, potential of merbau in area of IUPHHK-HA PT. WMT-II as yet available for the level of trees in primary and secondary forest. But, average potential of merbau is low in secondary forest. It is also happened on the level of poles. It indicates that natural regeneration process of merbau is very low.

Abstrak: Comprehensive Periodic Forest Inventory (IHMB) is a ten-year periodic forest inventory for establishing business plan of forest utilization, which had to be done by Business Utilization Timber Forest Product in Natural Forest (IUPHHK-HA) and Plantation Forest (IUPHHK-HT) permit holders based on Government Regulation No. 6 of 2007. PT. Ratah Timber as a business license holder of Business Utilization Timber Forest Product in Natural Forest (IUPHHK-HA) requires preceding IHMB for establishing Ten-Years Natural Forest Business Plan for Timber Forest Product Utilization. IHMB with sampling concept reducing data measurement area to small certain surveyed area. Spatial distribution of timber potential from overall IHMB area, which in some compartment is not represented, may be estimated using spatial interpolation using GIS from data that obtained in survey plots. This research intend to estimate forest standing stock, establishing map of timber volume and tree profile, and analyzing forest timber potential in PT. Ratah Timber, East Kalimantan. IHMB tabular data processing shows that more that 60% of standing stock in PT. Ratah Timber belongs to Kayu Meranti (KM) class in all trees growing class (pole, small trees and large trees). Largest tree density is available at pole class by 206 poles/ha, meanwhile largest volume is available at large tree class by 146,73 m3/ha and overall standing quality is considered good based on its tree quality. IHMB spatial data distribution shows that PT. Ratah Timber has the largest area or compartments in lowest class potential. Spatial distribution map for large trees inform that largest compartment aggregated at 0-24 N/ha and 0-146.6 m3/ha in density and volume distribution classes. Potential analysis and tree spatial distribution overlay for 50 cm up commercial tree diameter shows normal standing structure condition, in spite of its potential condition was not too high, about 79,8% of PT. Ratah Timber area only having 0-28 trees/ha tree density with 0-279,6 m3/ha standing volume.

Judul: Perancangan Proses Produksi Telur Asin Rendah Kolesterol
Abstrak: Telur asin merupakan produk olahan telur yang digemari masyarakat, tetapi mengandung kolesterol yang melebihi batasan konsumsi harian manusia. Tahap pengolahan, telur asin direndam dalam larutan khusus guna menurunkan kandungan kolesterol di dalam telur. Proses ini melibatkan pengaturan waktu pemeraman, konsentrasi larutan, dan bahan-bahan lainnya untuk mencapai hasil yang diinginkan. Formulasi telur asin yang terpilih yaitu pemeraman selama 12 hari dalam larutan garam 32,5% yang dicampur bawang putih, sereh, dan daun jeruk cincang, perendaman dalam larutan soda 20% selama 4 jam, dan dikukus selama satu jam. Kadar kolesterol sebesar 233,39 mg/100 g pada hari pertama dan mengalami penurunan menjadi 131,61 mg/100 g pada hari kesepuluh., Salted eggs are a popular egg product among the community, but they contain cholesterol that exceeds the daily human consumption limit. In the processing stage, the salted eggs are immersed in a special solution to reduce the cholesterol content inside the eggs. This process involves adjusting the soaking time, solution concentration, and other ingredients to achieve the desired results. The selected salted egg formulation is marinating for 12 days in 32.5% salt solution mixed with garlic, lemongrass, and chopped lime leaves, marinating in 20% soda solution for 4 hours, and steaming for one hour. The cholesterol level was measured at 233.39 mg/100g on the first day and decreased to 131.61 mg/100g on the tenth day.
