Abstrak: Gaps formed by the loss of one or several trees. Gap phase is the initial phase of forest natural regeneration. The purpose of this research is to analyze the pattern of natural regeneration development in forest gaps and forest stand composition at IUPHHK-HA PT. Sarpatim. Analysis of gap natural seedlings composition used single plot and analysis of forest stands used nested line plot at TPTJ and conservation forest area. Results showed that the number of plants species much more on large gaps with species composer is dominated by pioneer species such as Macaranga hypoleuca, M. gigantea, and Breynia oblongifolia otherwise small gaps is dominated by climax species such as Hopea dryobalanoides, Syzygium borneense, Shorea laevis, etc. Dominance values overall is low (C near to 0), richness value is high (R > 5), and diversity value is medium (2 < H’ < 3) up to high (H’ > 3). Result of Pearson correlation test showed that gap size positively correlated with the dominance, richness, and diversity values with the strength of correlation is weak. Forest stand species composition at research sites dominated by the dipterocarp groups such as Shorea smithiana, S. parvifolia, S. leprosula, S. laevis, and Dipterocarpus caudiferus. Dendogram clusters of species similarity do not follow the trend that closeness of felling age has high similarity values due to the high variation of forest sites, microclimate, and forest management activities.

Judul: Komposisi Functional Species Group pada Sistem Silvikultur Tebang Pilih Tanam Jalur di Area IUPHHK-HA PT Sarpatim, Kalimantan Tengah
Abstrak: Forest management can have an impact on changes in forest structure and composition of plant species. Functional species Group (FSG) may explain the unity of the trees species that are selected in a group in a forest management activities so that it can help in explaining the characteristic of biodiversity such as the quality of habitat and ecosystem processes. The purpose of this research is to know the composition of forest vegetation that the production system are managed with a Silvikultur system of TPTJ as seen from the forest structure and composition of the type that belongs to FSG for the stands and natural regeneration in log over area (LOA) and KPPN (The Conservation of Germplasm Area) IUPHHK-HA PT Sarmiento Parakantja Timber (Sarpatim), Central Kalimantan. Analysis of the composition of the stands type and structure used terraced path in the area of TPTJ and KPPN. The results showed that the types of climax on an entire swath of observations, generally have greater proportion than the group of pioneers, the number of the climax type is 100 while pioneer type is 59. The structure of the stands form a J reverse curve, it show that the composition of vegetation recovery on log over areas managed by using TPTJ and KPPN Silvikultur system has balance characteristic of uneven age forest. The value of diversity is high (H'>3). Most of tree and stands community have different communities (ID>50%).

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.
