Tepung ikan merupakan salah satu komoditas penting akuakultur yang permintaannya di Indonesia meningkat setiap tahun seiring pesatnya perkembangan akuakultur. Sebagian besar kebutuhan tepung ikan tersebut dipenuhi dari impor. Salah satu upaya untuk mengurangi kebutuhan impor adalah  memanfaatkan berbagai jenis ikan rucah dan sisa olahan ikan berupa tulang dan kepala ikan sebagai bahan baku tepung ikan. Permasalahan yang dihadapi pada pengolahan tulang ikan adalah proses pencacahan menjadi ukuran yang lebih kecil. Oleh karena itu diperlukan mesin yang mampu mencacah tulang ikan yang memiliki tekstur keras. Telah dilakukan perancangan, pembuatan dan pengujian kinerja mesin pencacah tulang ikan. Mesin dirancang berdasarkan mekanisme kerja poros berputar untuk menggerakkan sepasang mata pisau yang saling berhimpitan dan berputar berlawanan arah. Uji kinerja dilakukan dengan beban tulang ikan tuna dengan variasi perlakuan frekuensi inverter 25; 37,5; dan 50 Hz. Parameter yang diamati meliputi rendemen, kecepatan putaran poros, waktu pencacahan, dan kapasitas pencacahan. Hasil uji coba menunjukkan bahwa semakin tinggi frekuensi inverter, kecepatan putaran poros semakin tinggi, sehingga kapasitas pencacahan semakin meningkat. Berdasarkan parameter yang diamati, mesin bekerja optimal pada frekuensi inverter 50,0 Hz.  AbstractFish meal is one of the essential inputs for aquaculture, and the demand in Indonesia is growing every year parallel with the rapid development of aquaculture. Most of the fish meal was imported. An effort to reduce imports is to utilize various types of trash fish and fish processing waste, including bones and head as raw material for fish meal. The problem that occurs in the processing of fish bone is the process of chopping them into smaller sizes. Therefore, a machine capable of chopping hard texture of fish bones is needed. The design and performance tests of the fish bone chopping machine have been conducted. The device was designed based on the working mechanism of the rotating shaft to drive the paired blades that coincide and rotate in the opposite direction. The performance test was carried out for tuna bone with varied inverter frequencies of 25; 37,5; and 50 Hz. The parameters observed were yield, shaft speed, chopping time, and capacity. The results showed that increasing inverter frequency increased the shaft speed; therefore, it increased the capacity. Based on the observed parameters, the machine worked optimally at an inverter frequency of 50,0 Hz.

BACKGROUND: Few studies have investigated the variations in body composition and performance in Japanese collegiate American-football players. OBJECTIVE: To clarify what characterizes competitors at the highest levels – in the top division or on the starting lineup – we compared players’ body compositions and performance test results. METHODS: This study included 172 players. Each player’s body composition and performance (one-repetition maximum bench press, one-repetition maximum back squat, and vertical jump height) were measured; power was estimated from vertical jump height and body weight. Players were compared according to status (starter vs. non-starter), position (skill vs. linemen), and division (1 vs. 2). Regression analysis was performed to determine characteristics for being a starter. RESULTS: Players in higher divisions and who were starters were stronger and had more power, greater body size, and better performance test results. Players in skill positions were relatively stronger than those in linemen positions. Vertical jump height was a significant predictor of being a starter in Division 1. CONCLUSION: Power and vertical jump may be a deciding factor for playing as a starter or in a higher division.

Network security technology ensures secure data transmission in network. Meanwhile, it brings extra overhead of security system in terms of cost and performance, which seriously affects the rapid development of existing high-speed encryption systems. The existing encryption technology cannot meet the demand of high security, low cost and high real-time. For solving above problems, an ECC encryption engine architecture based on scalable public key cipher and a high-speed configurable multiplication algorithm are designed. The algorithm was tested on FPGA platform and the experiment results show that the system has better computation speed and lower cost overhead. By comparing with other systems, our system has benefits in terms of hardware overhead and encryption time ratio
