The operation of conventional roast has many disadvantages, that is combustion air intake cannot be controlled and excess air intake will cause charcoal fuel to run out quickly. Operation of conventional equipment can also cause work accidents because excessive sparks from burning charcoal and charcoal smoke will disrupt the health of the operator. One of innovation in overcoming these problems is by designing and manufacturing a fish roasting machine with rotary system. This machine uses an electric motor ¼ HP. Round for roasting is 3 RPM. Based on the performance test, the roasting temperature is 185 oC. The length of time for roasting catfish, tongkol and kuniran is 10, 11 and 13 minutes respectively while the roasting capacity is 126, 114 and 96 tails/hour. The amount of charcoal fuel needed for roasting catfish is 0.8 kg, tongkol is 0.9 kg and kuniran is 1.1 kg. Total energy including electricity and energy from charcoal for catfish is 25,712.5 kJ, tongkol is 28,923.75 kJ/kg and kuniran is 35,346.25 kJ / kg. The main cost of catfish roasting is Rp. 332 /tail, tongkol is Rp. 374 /tail and kuniran Rp. 432 /tail.

Abstrak. Pengolahan biji melinjo menjadi emping melinjo saat ini sebagian besar masih menggunakan cara tradisional (manual) yaitu dengan memukul-mukul biji melinjo menggunakan palu yang sebelumnya sudah disangrai dengan pasir. Teknik ini dirasakan tidak efektif karena memerlukan waktu yang cukup lama dan tenaga manusia yang besar. Untuk mengatasi masalah tersebut perlu dibuat suatu mesin untuk memudahkan dalam pemipihan biji melinjo. Penelitian ini bertujuan untuk desain mesin pemipih emping melinjo dengan sumber tenaga motor listrik,  menguji fungsional dan kinerja mesin serta membandingkannya dengan  metode tradisional. Parameter yang diamati meliputi kapasitas kerja mesin serta persentase kehilangan hasil. Hasil penelitian diperoleh bahwa mesin pemipih emping melinjo tipe tumbukan mempunyai ukuran panjang 820 mm, lebar 520 mm dan tinggi 1010 mm, digerakkan dengan motor listrik dengan daya 1.5 hp 1450 rpm. Hasil pengujian mesin didapatkan kapasitas pemipihan 0.83 kg/jam sedangkan kapasitas secara manual 0.16 kg/jam. Persentase kehilangan hasil dari pemakaian mesin pemipih emping ini adalah 1.5 %  sedangkan dengan cara manual adanya kehilangan hasil yaitu sebesar 7 %.  Design and Performance Test Of Flatter Machines  Impact Type for Melinjo (Gnetum gnemon)Abstract. Flatteting of melinjo seeds into melinjo chips at this time most still use the manual method by beating the seeds of melinjo using a hammer that was previously roasted with sand. This technique is felt to be ineffective because it requires a long time and a large amount of human energy. To overcome these problems, a solution is needed to facilitate flattening the seeds of melinjo. This study aims to design melinjo chips flattening machine with an electric motor as a power source, to test the functionality and performance of the machine, and to compare it with traditional methods. The parameters observed include the machine's working capacity and the percentage of yield loss. The results showed that this flatter machines impact type for melinjo has a length of 820 mm, the width of 520 mm, and a height of 1010 mm, driven by an electric motor with a power of 1.5 HP with a rotation of 1450 rpm. The results of testing the device obtained a flaking capacity of 0.83 kg/hour while the capacity manually was 0.16 kg/hour. The percentage of loss of results from the use of this emping flask is 1.5% while by manual the loss of results is equal to 7%.

The Embung Bengawan Project in Tarakan City has several jobs requiring heavy equipment including mechanical soil removal activities. Activity of mechanical soil movement is a series in work of loading and transportation equipment. In order to achieve optimal mechanical soil removal targets, it is necessary to know the performance of the machine during the mechanical soil removal process. The optimization of production is the way to obtain production that is in accordance with optimal conditions of mechanical devices. This paper discusses the optimization of dump truck queue time and the number of dump trucks. Performance calculation tool using the method of production capacity of the tool, and calculate the optimal queue using the Queue Model method. Calculation using queuing model method obtained by result of time required by 3 excavator unit and with combined amount of dump truck will give result of cost equal to Rp 48,097,711 / day, and dump truck waiting time in queue to 1 minute. Then the optimal time is obtained by operating 3 units of excavators with a cost difference of Rp 3,572,826 / day from the real condition of the field that operates 2 excavator units

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.

Microstructural changes occurring in biomedical Co-Cr-Mo alloys with three carbon levels due to solution treatment and aging were investigated. Ingots of Co-Cr-Mo alloys with three different carbon levels were prepared by vacuum furnace melting; their chemical composition was Co-28Cr-6Mo-xC (x = 0.12, 0.25 and 0.35 mass%). Precipitates were electrolytically extracted from as-cast and heat-treated alloys. An M23C6 type carbide and a phase were detected as precipitates in as-cast Co-28Cr-6Mo-0.12C alloy, and an M23C6 type carbide and an  phase (M6C-M12C type carbide) were detected in as-cast Co-28Cr-6Mo-0.25C and Co-28Cr-6Mo-0.35C alloys. Only the M23C6 type carbide was detected during solution treatment. Complete precipitate dissolution occurred in all the three alloys after solution treatment. The holding time required for complete precipitate dissolution increased with increasing carbon content and decreasing solution treatment temperature. Complete precipitate dissolution occurred in the Co-Cr-Mo-C alloys solution treated at 1523 K for 43.2 ks; they were then subjected to aging from 873 to 1473 K for a heating time up to 44.1 ks after complete precipitate dissolution in solution treatment at 1523 K for 43.2 ks. The M23C6 type carbide with a grain size of 0.1–3 m was observed after aging. A time-temperature-precipitation diagram of the M23C6 type carbide formed in the Co-28Cr-6Mo-0.25C alloy was plotted.
