Judul: Perubahan penutupan lahan dan analisis faktor penyebab perambahan kawasan Taman Nasional Gunung Ciremai
Abstrak: Gunung Ciremai National Park (GCNP) is one of the conservation areas that has been facing forest land cover changes due to uncontrolled activities of people around the area. They have been practicing shifting cultivation system for horticulture that can lead to forest conversion and land cover changes especially fields in GCNP area. Data and information of the conditions in GCNP area can be analyzed through technology Geographic Information System (GIS). The aim of this research was to know rate of land cover and spatial distribution on land cover in GCNP for year periods of 2006-2009 and investigate socio-economic factors that influence expansion in GCNP. Data on sosial and ground control point were taken in GCNP for one month in July 2010. Collected data included spatial data in the form of maps, Landsat image ETM+ year 2006 and TM year 2009 and attributed data including socio-economic conditions, knowledge and attitude of people. Spatial data were analyzed using Geographic Information System (GIS) technology. The results of image processing were analyzed qualitatively and quantitatively using the attribute data to determine its impact on land cover changes. Land cover types in GCNP consisted of virgin forest, pine plant forest, shrubs, fields, water bodies, open land and no data. In the period 2006-2009, there were either increases or decreases in land cover areas. Land cover of open land was decreased by 979.2 ha (-2.26%) with the largest in Pasawahan Subdistrict, virgin forest by 51.21 ha (-0.01%) with the largest in Cigugur Subdistrict and water bodies by 1.62 ha (0.08%). On the other hand, land cover of fields was increased by 178.29 ha (0.18%) with the largest in Argapura Subdistrict, shrubs by 746.73 ha (0.18%) with the largest in Pasawahan Subdistrict and pine plant forest by 92.88 ha (0.06%) with the largest in Cilimus Subdistrict. Socioeconomic factors that influenced expansion of land cultivation into the park areas were rate of income in outside area, knowledge especially on cover function and attitude of people to the existing forest. To anticipate expansion of land cultivation into the forest area, the national park should create alternative beneficial projects in order to improve people income outside national park zone, rehabilitation of zone of natonal park and supervise the activities to people about national park.

Judul: odels of Land Cover Change using Multi Layer Perceptron and Logistic Regression Methods in Gunung Ciremai National Park
Abstrak: Taman Nasional Gunung Ciremai (TNGC) merupakan salah satu kawasan pelestarian alam yang ada di Provinsi Jawa Barat. TNGC ditunjuk sebagai taman nasional berdasarkan Surat Keputusan Menteri Kehutanan No. 424/Menhut-II/2004 tanggal 19 Oktober 2004. Sebelum ditetapkan sebagai taman nasional, kawasan hutan Gunung Ciremai merupakan hutan lindung dan hutan produksi yang dikelola oleh Perum Perhutani. Dalam pengelolaan hutan produksi, Perum Perhutani mengembangkan sistem Pengelolaan Hutan Bersama Masyarakat (PHBM). Sistem ini memperbolehkan masyarakat untuk menggarap kawasan dengan pola tumpang sari. Pengelolaan dengan sistem ini sedikit banyak mempengaruhi tutupan lahan kawasan Gunung Ciremai. Perkembangan perubahan tutupan lahan suatu wilayah dapat diketahui dengan memanfaatkan data penginderaan jauh (remote sensing) berupa citra satelit multitemporal. Perkembangan perubahan tutupan lahan sangat penting untuk diketahui, agar pola perubahan tutupan lahan dimasa datang dapat diprediksi sehingga perubahan penutupan lahan yang bersifat negatif dapat dicegah atau dikurangi. Penelitian ini bertujuan untuk mengkaji perubahan penutupan lahan secara spasial di TNGC dari tahun 2000 sampai dengan tahun 2008 dan menyusun pemodelan perubahan penutupan lahan di TNGC pada tahun 2016 dengan metode Multi-layer Perceptron (MLP) dan Logistic Regression (Logit) berdasarkan perubahan penutupan lahan tahun 2000–2008. Metode pemodelan yang digunakan dalam penelitian ini adalah MLP dan Logit. Sedangkan variabel bebas yang dapat mendorong terjadinya perubahan penutupan lahan yang digunakan dalam penelitian ini adalah kemiringan lereng, jarak dari jalan, jarak dari pemukiman, dan kepadatan penduduk. Hasil penelitian menunjukkan bahwa perubahan penutupan lahan di kawasan TNGC yang terjadi pada periode 2000–2008 adalah adanya peningkatan luas penutupan lahan terbuka sebesar 898.87 ha. Hal ini diikuti dengan penurunan luas penutupan hutan pegunungan, hutan tanaman dan semak masing-masing sebesar 79.59 ha, 11.06 ha dan 808.22 ha. Sedangkan penutupan lahan yang tidak mengalami perubahan adalah badan air, hutan dataran rendah, hutan sub alpine dan kawah. Selama periode tahun 2008–2016 sebanyak 6 penutupan lahan tidak mengalami perubahan, antara lain badan air, hutan dataran rendah, hutan pegunungan, hutan sub alpine, hutan tanaman dan kawah. Penurunan dan peningkatan luas hanya terjadi pada penutupan lahan terbuka dan semak masing-masing sebesar 1907.91 ha. Hasil validasi antara peta prediksi penutupan lahan metode pemodelan MLP dan Logit dengan peta penutupan lahan aktual tahun 2016, diperoleh nilai akurasi sangat baik dengan nilai kappa untuk MLP sebesar 0.8995 dan untuk Logit sebesar 0.8989, sehingga model dapat diaplikasikan untuk prediksi penutupan lahan pada tahun-tahun yang akan datang., Gunung Ciremai National Park (TNGC) is one of the nature conservation area in West Java Province. TNGC is designated as a national park based on Ministry of Forestry Decree no. 424 / Menhut-II / 2004 dated October 19, 2004. Before being designated as a national park, the forest area of Mount Ciremai was protected forest and production forest managed by Perum Perhutani. In the management of production forests, Perum Perhutani developed a Collaborative Forest Management (PHBM) system. This system allows people to work on areas with intercropping patterns. This system of land management affects the land cover of Mount Ciremai area. The development of land cover change of a region can be known by utilizing remote sensing data in the form of multitemporal satellite imagery. The development of land cover change is important to know, so

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.
