Judul: Evaluasi ketepatan luaran data CMORPH untuk interpolasi data hujan di Indonesia
Abstrak: Kebutuhan akan informasi data hujan yang semakin meningkat namun tidak diiringi dengan ketersediaan tenaga ketja. Alternatif yang sedang berkembang saat ini adalah menggunakan data estimasi satelit yang umumnya masih bersifat global. Studi ini mengevaluasi tingkat ketepatan luaran data CMORPH untuk mengestimasi nilai tujuan di suatu wilayah berdasarkan tipe hujan wilayah terkait. Studi ini dilakukan melalui 5 tahap yaitu: (i) Memperoleh estimasi hujan dari luaran CMORPH dengan melakukan downscoling data tersebut untuk setiap wilayah studi dengan mengambil domain 1x1 (grid sesuai dengan posisi stasiun), domain 3x3, dan domain 5x5; (ii) Analisis komponen utama untuk mendapatkan komponen terbaik dari domain 3x3 dan domain 5x5; (iii) Membangun model hubungan antara hujan observasi dan CMORPH dengan regresi sederhana; (iv) Membangun model hubungan antara hujan observasi dengan komponen utama terpilih; (v) validasi keterandalan model dengan menggunakan data tahun terakhir. Hasil studi ini menunjukkan bahwa luaran data CMORPH pada domain 3x3 sudah cukup mampu menghasilkan nilai estimasi hujan pada titik tertentu yaig mendekati nilai observasinya.

Judul: Estimasi curah hujan berdasarkan data CMORPH (CPC MORPHing Technique) wilayah Riau
Abstrak: Rainfall is the most important climate element in Indonesia which has a very large variation compared with other climate elements. High variability will lead to limited rainfall data. The accurate data and information will support the development of rainfall prediction using remote sensing. CMORPH (CPC MORPHing Technique) is one of the new techniques developed by NOAA in predicting the amount of rainfall and global precipitation with high spatial and temporal resolution. Therefore, it is necessary to do a statistical downscaling technique approach based on partial least squares analysis (PLS). This research aims to analyze the potential for rainfall prediction data CMORPH surface.The model development is based on allegations precipitation method Partial Least Squares (PLS) in Pekanbaru, Japura Rengat, Tanjung Pinang, and Dabo Singkep. The research area is divided into five domains; domain 1x1, domain 3x3, domain 5x5, domain 7x7, and domain 9x9. The reliability model is shown by the allegations of the correlation coefficient value, Root Mean Square Error (RMSE), and Pearson test. Rainfall CMORPH is similar to the pattern of surface rainfall variation able to represent 10.7% to 47.5% variability of rainfall. Downscaling using Partial Least Ssquare technique (PLS) is better than downscaling techniques using simple regression, where using PLS can increase the determination coefficient value (R2) from 47.5% by using simple regression to 98.7% by using PLS. Based on model validation, precipitation allegations is similar to the pattern of rainfall area, except in the wet months. If observed from the region it can be seen that for Earth's surface a domain that provides the best result is the domain 5x5. Meanwhile, for the Islands, domain 3x3 offers the best performance. This is due to conditions in the region, where the Islands is influenced by the ocean. Therefore, rainfall CMORPH is better used to predict the precipitation on the continent surface.

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.
