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: Pemulihan Vegetasi di Areal Hutan yang Dikelola dengan Sistem TPTJ (Studi Kasus di Areal IUPHHK-HA PT. Suka Jaya Makmur, Kalimantan Barat)
Abstrak: Massive utilization of forest resources became one factor which caused degradation on natural forest. Forest degradation which occurred continuously could cause a change in forest composition. This could happen because seedling from invasive species dominated the area of natural forest. This research aimed to determine the composition and structure recovery of forest stands managed by TPTJ system on area of IUPHHK-HA PT. Suka Jaya Makmur, West Kalimantan. The results showed that non-commercial Dipterocarp species group had the biggest value of density and proportion among all levels Dipterocarp. Curve diameter distribution showed a balanced logged forest. The diversity in all plotarea was high. Kelampai and meranti were dominated in canopy level. Jambu monyet and kelampai were the species that dominated in seedling level. Tree and seedling had a different composition, it was shown by the ID value at >50%. This was shown by cluster analysis which divided into four groups. Commercial species proportion was generally larger than other non-commercial species.

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.
