Item Rancang Bangun Pembangkit Listrik Tenaga Biogas Untuk Daerah Sei Temiang(Politeknik Negeri Batam, 2012-08-03) Suprianto, Fahrur; Istardi, DidiDesign of Biogas Power Plant is a research campus to meet the needs of new renewable energy and environmentally friendly. Then conducted the research with engineering scale biogas power plant in the area of domestic Sei Temiang Batam. By utilizing livestock waste contained in the sei temiang, Batam, so we try to build biogas power plants around the farm area. In the process of implementation, this design, the location where digester for decomposition can not be far from the ranch, because the source used is cow dung. And for a mixture of water, the water used is fresh water, or use the nearest water source around the farm area. Temperature to be one important factor for the decomposition, because the temperature is well open to the biogas production ranged 30-55 C , therefore the digester should be placed in an open space exposed to direct sunlight. Prototype plant uses a mixture of cow dung and water (with a ratio of 1:1) as much as 576 liters. Volume of gas produced as much as 624 liters. This gas volume can be used to power electricity for 35 minutes with a power output of 700 WattItem Rancang Bangun Auto Transfer Switch Menggunakan Triac(Politeknik Negeri Batam, 2017-02-10) Maulana Dalimunthe, Muhammad Arief; Gozali, M. SyafeiThe availability of electrical power from utility sometimes disturbed, be it from internal of the system like equipment failure or from external of the system like nature phenomenon, so it will obstruct daily activities. However if the activities are urgent, so disturbance of electrical power is not allowed. It cannot help but must use backup supply that generally obtained from diesel generator that usually called genset. Despite that, turning the genset on manually there will be a rather long time delay so it is not too effective if the activities need to handled fast. Therefore this research is useful to solve that problem. This device uses three modes, those are Manual PLN, Manual Genset, and Auto. Manual PLN and Manual Genset mode, the transfer of electricity supply done manually. Meanwhile Auto mode transfers electricity supply by detects which supply available and then transfer it to load. The detection done by converting PLN’s AC supply to DC then directing it to Arduino microcontroller which will process incoming input then triggers TRIAC PLN or TRIAC Genset based on the status of PLN’s supply so power will flow to load pass through the TRIAC. This device can do the switching with good timing accuracy that matches with the programmed delay in microcontroller with nominal current 6A.Item Trainer R-L-C(Politeknik Negeri Batam, 2017-02-24) Bagus Saifullah, Achmad; Arifin, MuhammadLearning achievement of the students affected various factors that influence these factors one of which is of many kinds of learning. Instructional media used when prises learning. A media that can help learning about electronics components, namely resistor, inductor, and capasitor. A media call name is Trainer R-L-C. Making this Trainer R- L-C need ingredients like box size 30x40, banana socket, pcb board, and some components of electro like (resistor, capasitor, diode, lowering the voltage regulator, and IC NE555). From observations made on experiemental tool RLC NE555, it can be conclude that the greater the voltage in use, the greater the frequency generated. Calculations produced by the oscilloscope is not much different from the manual calculation, but more precise and easier if you use an osilloscope.Item Mesin Penyemprot Hama Tanaman(Politeknik Negeri Batam, 2017-02-27) Vandmme Simangunsong, Nico; Arifin, MuhammadTo reduce the heavy work of farmers , then a machine Sprayers Plant Pest can be used to ease the work of farmers and can reduce work of farmer in the fields. The device will work as you want if the rotary switch is rotated. There is 3 condition is serve in this device, mean Low, Medium, High. Voltage when low condition is 7 volt, and voltage when medium condition is 9 volt and voltage when high condition is 11 volt.Item Pengontrol Conveyor Pada Mesin Pengering Ikan Teri(Politeknik Negeri Batam, 2016-12-29) Chairuddin; Wivanius, Nadhrah; Ridwan, RidwanIn the traditional process of drying anchovy should be stocked on top of the drying container so that the anchovy can be dried evenly, stocking here done manually which is stocked directly by hand so that this process can degrade the quality of anchovy, because becoming less hygienic. Therefore we need a spreader tool anchovy automatically. Here the researchers used as a spreader conveyor anchovy. Conveyor is designed to facilitate the drying machine anchovy in spreading the fish inside the machine. The working principle of this tool is to utilize the force of gravity to make the anchovy down from the entrance of the machine for the next fall to the first conveyor, then be dropped into a second conveyor with a spread to proceed to the drying process. Based on research that has been done the tool is able to spread 11 kg of anchovy in one time production.Item Simulasi Saklar Transfer Otomatis Menggunakan Arduino Dan Pengiriman Pesan Otomatis(Politeknik Negeri Batam, 2017-08-21) Azarya Dongoran, Septian; Prayoga, SenanjungThe main power supply is PLN (State Power Plant) is not always continuous in distribution, a time must occur blackout that may be caused by interference on the transmission system or distribution system. To anticipate the outage, in this final project I will make ATS (Automatic Transfer Switch) by using arduino program the data communications system receives and sends the commands to the circuit for moving the electrical home from PLN to the generator generator and vice versa, and then before the switching , GSM sim800l will send short message information via SMS smartphone the user, with in obtaining this automatic message then we can know information about genset in this simulation tool presented in genset instead of indicator light.Item Rancang Bangun Alat Pengaduk dan Penyaring Kerupuk Atom Otomatis untuk Usaha Kecil Menengah di Masyarakat Daerah Moro(Politeknik Negeri Batam, 2017-02-24) Supianto; Febriansyah Juwito, ArifCracker is one of the foods consumed in Indonesia. especially in the area of the village. One of the many produced crackers is in sub district of Moro, production process the crackers in the area of Moro, still using manual equipment, using a small spatula as a tool to stir the cracker at a time when the process of frying, so that when the crackers are produced in large numbers. of course a small spatula is usually used can not give comfort to the user. For that it is designed to provide convenience to users in producing crackers. The working principle of this instrument by way of stirring the crackers during frying in accordance with the desired time. Testing this tool has produced a time of maturity crackers faster than manually. In a frying pan crackers 1 and 2 kg capacity with this tool has the maturity of 3 and 5 minutes faster. Where to use this tool only takes 20 minutes to 1 kg and 45 minutes for 2 kg, while the frying manually takes time for 23 minutes to 48 minutes and 1 kg to 2 kg.Item Rancang Bangun Alat Pengaduk dan Penyaring Kerupuk Atom Otomatis Untuk Usaha Kecil Menengah di Masyarakat Daerah Moro(Politeknik Negeri Batam, 2017-02-24) Rahmadhany; Febriansyah Juwito, ArifCracker is one of the foods consumed in Indonesia particularly in the area of the Township. Prawn crackers and crackers fish is the most common type of crackers found in Indonesia, one of the many crackers is in region kecamatan Moro, crackers production processes in the area of kecamatan Moro, from the stirring process the crackers are still utilizing a small spatula and a screening process still utilizes filters that are still manual.
