Judul: Kajian tekno ekonomi industri kue kering berbahan baku sagu ubi jalar dan kacang hijau di Kabupaten Bogor
Abstrak: Indonesia is a contry with a high population growth and various natural resources. These great natural resources are potential to fulfill the needs of food.Two varietis of Indonesia's agricultural commodities are tuber crops and legumes. Both resources are potential crops to be utilized as source of food. Utilization of local food resources could be developed through its processed product. Product development is focused on creating a new product that meets the consumer requirements. Nowadays consumer require a product that is practical, available in any size, and easy to find. Cookies is a product that fits the criteria, therefore a cookies product with a sago, sweet potato and mung bean as main ingredients is developed.

Judul: Analysis of the Development of Superior Food Crop Commodities at Subdistrict Level in Bogor Regency
Abstrak: Kabupaten Bogor memiliki potensi dalam pengembangan subsektor tanaman pangan yang berperan besar terhadap perekonomian dan ketahanan pangan daerah. Penurunan luas lahan pertanian menjadi masalah yang dihadapi dalam pengembangan subsektor tersebut sehingga dibutuhkan upaya untuk mengoptimalkan pemanfaatan lahan melalui pengembangan komoditas unggulan. Penelitian ini bertujuan untuk (1) Mengidentifikasi komoditas unggulan tanaman pangan pada tingkat kecamatan di Kabupaten Bogor; (2) Menganalisis tingkat spesialisasi dan lokalisasi dari komoditas unggulan tanaman pangan; (3) Menganalisis prioritas pengembangan komoditas unggulan tanaman pangan pada tingkat kecamatan; dan (4) Menganalisis upaya pengembangan komoditas unggulan tanaman pangan oleh Pemerintah Daerah Kabupaten Bogor. Metode yang digunakan dalam penelitian antara lain metode analisis deskriptif, location quotient (LQ), kuosien spesialisasi, dan kuosien lokalisasi. Hasil penelitian menunjukkan bahwa komoditas tanaman pangan dengan wilayah basis terbanyak di Kabupaten Bogor adalah padi sawah, kacang tanah, ubi kayu, ubi jalar, dan talas. Tidak ada spesialisasi dan pemusatan komoditas unggulan tanaman pangan pada tingkat kecamatan. Semua komoditas tanaman pangan menjadi komoditas yang diprioritaskan untuk dikembangkan pada tingkat kecamatan. Pemerintah Daerah Kabupaten Bogor dan dinas terkait telah melaksanakan Program Peningkatan Produksi, Produktivitas, dan Nilai Tambah Tanaman Pangan yang terdiri dari kegiatan pengelolaan produksi hingga pengolahan dan pemasaran produk hasil pertanian tanaman pangan., Bogor Regency has potential in the development of the food crop subsector, which has a major role in the regional economy and food security. The decrease in the area of agricultural land is a problem faced in the development of this subsector, so efforts are needed to optimize land use through the development of superior commodities. This study aims to (1) identify the superior commodities of food crops at the subdistrict level in Bogor Regency; (2) analyze the level of specialization and localization of superior food crop commodities; (3) analyze the priority of developing superior food crop commodities at the subdistrict level; and (4) analyze efforts to develop superior food crop commodities by the Regional Government of Bogor Regency. The methods used in this study include descriptive analysis methods, location quotient (LQ), specialization quotient, and localization quotient. The results showed that the food crop commodities with the largest base area in Bogor Regency are lowland rice, peanuts, sweet potatoes, cassava, and taro. There is no specialization and centralization of superior food crop commodities at the subdistrict level. All food crop commodities are prioritized to be developed at the subdistrict level. The Regional Government of Bogor Regency and related agencies have implemented the Program to Increase Production, Productivity, and Added Value of Food Crops, which consists of activities from production management to processing and marketing of food crop agricultural products.

Judul: Commissioning and Analysis Dose Distribution of Linear Accelerator FFF Elekta VersaHD Photon Mode 6 MV Using Monte Carlo Simulation
Abstrak: Commissioning model simulasi Linear Accelerator (Linac) dalam radioterapi perlu dilakukan untuk validasi keakuratan distribusi dosis. Metode yang digunakan adalah simulasi Monte Carlo menggunakan software EGSnrc, yang terdiri dari BEAMnrc untuk memodelkan Linac dan DOSXYZnrc untuk menghitung distribusi dosis pada fantom air. Penelitian ini bertujuan melakukan commissioning Linac Flattening Filter-Free (FFF) Elekta VersaHD moda foton 6 MV. Hasil commissioning menunjukkan distribusi dosis hasil simulasi memenuhi kriteria penerimaan hasil simulasi menggunakan energi awal elektron 6,9 MeV pada ukuran medan paparan 5 × 5, 10 × 10, dan 20 × 20 cm2. Dosis dan dmax meningkat seiring energi awal elektron yang makin besar. Percentage Depth Dose (PDD) mengalami penurunan dosis pada ukuran medan paparan yang lebih kecil. Profil dosis mengalami pelebaran pada ukuran medan paparan yang lebih besar. PDD Linac FFF mengalami penurunan yang lebih signifikan dibandingkan dengan PDD Linac Flattening Filter (FF). Profil dosis Linac FF dan Linac FFF menunjukkan perbedaan keseragaman nilai dosis pada daerah umbra., Commissioning a simulation model of the Linear Accelerator (Linac) in radiotherapy needs to be done to validate the dose distribution accuracy. The method used is Monte Carlo simulation using EGSnrc software, consist of BEAMnrc for modeling Linac and DOSXYZnrc for calculating dose distribution in a water phantom. This research aimed to commission the Linac Flattening Filter-Free (FFF) Elekta VersaHD 6 MV photon mode using Monte Carlo simulation. The commissioning results show that simulated dose distribution satisfied the acceptance criteria of simulation results using initial electron energy of 6,9 MeV at 5 × 5, 10 × 10, and 20 × 20 cm2 field sizes. The dose and dmax increased as the initial electron energy increased. Percentage Depth Dose (PDD) decreased at smaller field size. The dose profile widens at larger field size. PDD Linac FFF decreased more significantly than PDD Linac Flattening Filter (FF). The dose profile of Linac FF and Linac FFF shows differences in uniformity of dose values in the umbra area.
