Judul: Spatial Modelling for Distribution and Habitat Suitability of Invasive Alien Species Kirinyuh (Austroeupatorium inulifolium (Kunth) R. M. King & H. Rob) in Mandalawangi Resort Gunung Gede Pangrango National Park.
Abstrak: The existence of invasive alien species influenced the ecosystem, and at the same time could not be controlled. This could cause disturbance of ecosystem function and also declined forest value, ecologically and economically. Some national parks have been facing serious threat caused by invasive alien species and 37 species were identified in Gunung Gede Pangrango National Park (GGPNP). It is important to carry out this research in GGPNP since the information on the distribution and habitat suitability for invasive alien species, especially for kirinyuh, is still limited. The objectives of this research were to determine the distribution and habitat suitability model for kirinyuh and the suitability degree of GGPNP as habitat for kirinyuh. Binary Logistic Regression Analysis and Principal Component Analysis were used to predict probability of habitat suitability for kirinyuh. Fifty percent of recorded data was used to build a predictive model and the rest was used to validate the model. Habitat requirements were analyzed and quantified from digital topographic maps, ASTER DEM and Landsat 7 ETM+. The result showed that predictive model of habitat suitability for kirinyuh was affected by elevation, NDMI, NDVI, distance to farmland and distance to trail. The result suggested Principal Component Analysis was more appropriate for spatial modelling than Binary Logistic Regression.

Judul: Diversity and Distribution Patterns of Invasive Alien Species in Andongrejo Resort, Meru Betiri National Park
Abstrak: Spesies tumbuhan asing invasif (IAS) merupakan spesies tumbuhan yang tumbuh baik secara liar ataupun hasil introduksi di luar habitat alaminya yang keberadaannya dapat mengganggu spesies lokal. Introduksi spesies asing invasif di zona rehabilitasi dan penyebaran spesies yang tumbuh secara liar di Taman Nasional Meru Betiri berpotensi invasif. Penelitian ini bertujuan untuk mengidentifikasi komposisi vegetasi, keanekaragaman spesies tumbuhan asing invasif, dan pola sebaran tumbuhan asing invasif di Resort Andongrejo Taman Nasional Meru Betiri. Metode pengumpulan data yang dilakukan yaitu dengan analisis vegetasi, observasi lapang, dan studi literatur yang kemudian dianalisis secara kuantitatif. Berdasarkan hasil analisis spesies tumbuhan asing invasif yang terdapat di Resort Andongrejo teridentifikasi sebanyak 24 spesies memiliki pola sebaran mengelompok diantaranya pada zona rehabilitasi teridentifikasi 24 spesies dan zona rimba teridentifikasi 9 spesies dengan dominansi tertinggi pada spesies Chromolaena odorata dan Mikania micrantha., Invasive alien species (IAS) are plant species that grow either wild or introduced outside their natural habitat and whose presence can disturb local species. The introduction of invasive alien species in the rehabilitation zone of Meru Betiri National Park has the potential to be invasive. This research aims to do identify the composition of vegetation, the diversity of invasive alien species (IAS), and the distribution patterns of IAS at the Andongrejo Resort, Meru Betiri National Park. The data collection method used was vegetation analysis, field observation, and literature study which was then analyzed quantitatively. Based on the results of the analysis of IAS found at the Andongrejo Resort, 24 species were identified that had a clumped distribution pattern, including in the rehabilitation zone 24 species were identified and 9 species were identified in the jungle zone with the highest dominance being the species Chromolaena odorata and Mikania micrantha.

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.
