Bengkulu Province has many potentials such as beaches, conservation forests, plantations and others. Plantations in Bengkulu consist of smallholders and private / BUMN businesses. Smallholder plantations include coffee, black pepper, palm, rubber, areca nut and other gardens. The results of this plantation are still traditionally processed, which is drying and drying in the open with the help of solar heat. This drying process is still being implemented where the quality is poorly controlled. This has caused the yield of the plantation in Bengkulu to be unknown to other regions. like coffee in the Bengkulu area which has a distinctive taste characteristic compared to other regions. Coffee that is processed is Robusta or Arabica coffee which is the mainstay of the people of Air Raman Village, Bengkulu Province. The processing process is dried in the yard of the house, field, roadside and others. This drying and processing process is easily polluted from dust, animal waste, uneven drying. And the erratic drying time causes the villagers to need a machine or garden processing technology. One technology is a rotary dryer. Rotary drying machines can be used by utilizing regional potential such as solar energy, wind energy, water energy and others. In addition to Coffee, this village also has garden products such as black pepper, Pinang and others where the process is the same as the coffee harvest. The advantage of this dryer is a shorter drying time, the use of solar energy can minimize operational costs for drying coffee and black pepper. The dried coffee and black pepper are free from animal waste, dust and various other types of garbage and the process of drying more than 4 days from drying is done manually / in the public yard. This is because the temperature inside the drying machine is rotary higher than the open air, the level of dryness of coffee and black pepper is produced evenly, because the temperature in the rotary dryer is equipped with a stirrer evenly spread so that the stirring process is no longer necessary. . The working mechanism of this tool is expected to help people producing coffee and black pepper to dry their crops so that the quality of coffee and black pepper is good and the selling value is high. The output of PPM activities The application of science and technology is a high selling value that will increase people's income, improve people's welfare to be better and also create new jobs for the community as a producer of rotary drying machines. The availability of appropriate technology for the design and construction of rotary drying machines.

The quality of the seawater content for the grouper fish habitat is very influential in the grouper fish development process. Seawater quality for grouper fish habitat depend on temperatur, salinity, acidity (pH), and turbidity of seawater. The quality of seawater can be control by circulation in and out of seawater in the fish pond. This cycle is required to maintain the desired quality of seawater at temperatur 24ºC- 31ºC, salinity 30-33 ppt, dissolved oxygen> 3,5 ppt, and pH 7,5-8,3. In previous studies seawater control systems have been carried out in the form of controls temperatur and pH quality. Other components quality of sea water such as salinity and turbidity due to fish food also influence seawater quality for grouper fish habitat. Component control of sea water in this paper include microcontroller, pump sea water, fresh water pump, sensor and etc. In this paper we are focus on the controlling sea water quality to maintain the quality of grouper fish pools consisting of temperatur, salinity, acidity (pH), and turbidity of seawater. Input this data and the pH of the water read by the sensor will be processed with fuzzy logic to adjust the working of the salt water pump and the freshwater pump until it reaches the setpoint value. Turbidity and temperatur control using the ON-OFF system. The results show that of testing the sea water quality of control system using fuzzy logic in accordance with the calculation of mathematical defuzzyfication with an error of 0%. The values of salinity control system 31,14-32,98 PPT, pH 7,78-8,.2, temperatur 27ºC-29,98ºC, and turbidity level 9,90-14,85 NTU.

Generator listrik merupakan mesin pengubah energi mekanik menjadi energi listrik. Generator bekerja memanfaatkan sumber daya alam berupa air, angin, gelombang laut, batubara, bahan bakar dan lainnya. Pada gelombang laut, generator dapat digerakan secara translasi dan rotasi dengan sistem pneumatik. Komponen generator memanfaatkan gelombang laut dengan mekanisme pneumatik meliputi torak, tabung generator, lilitan kumparan, magnet neodymium, dudukan magnet, tabung pelampung dan lainnya. Generator gerak translasi dan rotasi menggunakan mekanisme pneumatik. Gerak translasi didapatkan dari gaya dorong torak akibat gerak turun naik gelombang yang diubah menjadi rotasi melalui penggunaan roda gigi. Generator translasi terdiri dari magnet permanen Neodymium berbentuk persegi, menggunakan diameter lilitan kumparan 0,7 mm. Generator rotasi menggunakan permanen magnet generator (PMG) dengan diameter lilitan kumparan 0,4 mm. pengujian performance generator dilakukan dengan variasi jarak celah 5–15 mm, variasi jumlah lilitan 920 dan 1260 lilitan pada pemasangan magnet dengan 1 sisi. Hasil pengujian performance generator tanpa beban menunjukan untuk jarak celah 5 mm didapatkan tegangan 21,7 Volt, arus 1,6 A pada gerak translasi. Untuk generator gerak rotasi tanpa beban keluaran tegangan yang dihasilkan adalah 41,8 V dan Arus 0,43 A. Pada Kondidi berbeban Performance generator translasi dan rotasi dengan beban 10 Watt jarak celah yang sama dihasilkan tegangan 17,2 Volt arus 0,42 A pada gerak translasi, pada gerak rotasi tegangan yang dihasilkan 64,5 V dan arus 0,42 A.
