Judul: Identifikasi Perubahan Tutupan Lahan Menggunakan Citra Landsat Multiwaktu dan Teknologi Sistem Informasi Geografis (SIG) di IUPHHK-HA PT. Austral Byna Kalimantan Tengah
Abstrak: The utilization of forest by Forest Concessions (HPH) or now known as The Forest Utilization License Timber-Forest Nature (IUPHHK-HA) brings many benefits but it also brings a downside for the Indonesian forestry. This activity has increased economic and regional development, but also lead to greater rates of deforestation and forest degradation as well. In general degradation that occurs in production forests result in damage or reduction of productive forest area to total forest area that will affect productivity. The negative impact of deforestation and degradation can be minimized through the efforts of a fast and efficient monitoring using remote sensing. Digital imagery or remote sensing data is one of the data to analyze the surface of the earth. Ministry of Forestry using Landsat imagery as one tool in monitoring the condition of Indonesia's forests. Landsat multi-time combined with Geographic Information Systems (GIS) facilitate the monitoring process. Both long-term monitoring and short-term monitoring can be controlled so that the rate of deforestation. This study aims to identify land cover classes as well as changes in the PT. Austral Byna in 1997, 2005 and 2012, and calculate the rate of degradation and reforestation arising from the use of forests in the periode of observations. The experiment was conducted in two phases, field phase in April-May 2012 in PT. Austral Byna, and image processing in June to November 2012 in the Laboratory of Remote Sensing and GIS Department of Forest Management Fahutan IPB. The data used are Landsat TM and ETM+ 30 m resolution coverage in 1997, 2005 and 2012 as well as other supporting digital maps. The tools used in the form of PC with the software ArcView 3.2, ArcGIS 9.1, Erdas 9.1, GPS, Camera and stationery. The result showed that successfully classified land cover both digital and visual consists of forests, fields, bushes, farm, vacant land and clouds. Degradation of the highest in 1997, 2005 and 2012 occurred in the class turned into a forest shrubs. While reforestation occurred in the highest class of the field and forest shrubs that turned into a forest.

Judul: Identifikasi perubahan tutupan lahan menggunakan Citra Landsat multiwaktu di IUPHHK-HA PT Sari Bumi Kusuma Kalimantan Tengah
Abstrak: Salah satu penyebab perubahan kondisi hutan ialah adanya kegiatan pengelolaan hutan yang tidak lestari. Dampak dari pengelolaan yang tidak lestari diantaranya adalah perubahan tutupan hutan menjadi non hutan dan penurunan kuantitas atau kualitas hutan. Upaya monitoring yang efektif dan efisien diperlukan untuk mendapatkan informasi yang akurat dan terkini tentang laju deforestasi dan degradasi hutan serta informasi reforestasi yang terjadi di PT Sari Bumi Kusuma (PT SBK). Upaya ini dapat dilakukan dengan menggunakan teknologi penginderaan jauh. Penginderaan jauh memiliki kemampuan untuk memberikan informasi secara lengkap, cepat, relatif akurat serta dapat memungkinkan untuk melaksanakan analisis multiwaktu dengan menggunakan teknologi citra Landsat. Tujuan penelitian ini adalah mengidentifikasi kelas tutupan lahan dan menghitung laju deforestasi, degradasi hutan serta reforestasi di areal PT SBK pada tahun 1989, 2000, dan 2014. Hasil pengolahan data menunjukan bahwa terdapat 6 kelas tutupan lahan yang memiliki nilai ketelitian pemetaan yang baik dengan nilai overall accuracy sebesar 93.02% dan kappa accuracy sebesar 89.91%. Luas hutan di IUPHHK-HA PT SBK pada tahun 2014 sebesar 125 823 hektar atau 85.24 % dari total luasan areal konsesi. Laju rata-rata deforestasi dan degradasi hutan pada periode 1989-2000 sebesar 812.63 ha/tahun dan laju rata-rata reforestasi sebesar 347.72 ha/tahun sedangkan pada periode tahun 2000-2014 laju rata-rata deforestasi dan degradasi hutan sebesar 764.50 ha/tahun dan laju rata-rata reforestasi sebesar 539.07 ha/tahun.

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.
