Energi Listrik adalah energi yang dibangkitkan dari generator kemudian disalurkan melalui Transmisi dan Gardu induk, kemudian disalurkan melalui jaringan Distribusi dan sampai ke konsumen rumah tinggal perkantoran, maupun industri. Tegangan yang di distribuskan sampai ke rumah tangga dengan tegangan yang diterima berkisar 220 Volt, dengan instalasi rumah tangga yang terpasangan beberapa peralatan rumah tangga. Instalasi listrik rumah tinggal yang baik terdiri dari sakelar dan stop kontak yang terhubung ke peralatan listrik. Instalasi listrik rumah tangga terdiri dari KWH meter, MCB, Sakelar peralatan rumah tangga (lampu, pompa) dan Stop Kontak.

Technological and economic developments are directly proportional to the industrial sector, especially in countries that are still developing. The food industry is one of them. Chocolate is one of the growing foods industri. The research on Comparison of the Drying Rate of Cocoa Beans Using a Dryer with Electricity and Solar Energy was carried out using an experimental method, namely with electricity coming from solar panels and then with electricity from PLN. The test aims to get a comparison of the effectiveness of electrical energy against solar panels. Cocoa beans that will be tested for drying before must be fermented first. The purpose of this test is to determine the drying time in a cocoa bean dryer with electricity and solar panels. This test uses the drying method using solar panels and uses electricity. Heat transfer in this test is conduction and convection. Test results are carried out in two stages. the first stage using electrical energy with the result of drying using cocoa beans weighing 2000 grams with a 271watt heater with the highest temperature of 43.6 0C can reduce the water content by around 59% from the mass of the 2000 gram sample weight of cocoa to 812 grams. The second stage is using solar panels where the drying process is divided into 2 stages, the first 8 hours with solar power and solar panels then the next stage using the help of batteries in the afternoon until evening. This stage can produce dry cocoa beans weighing 800 grams of dry cocoa beans from 2000 grams of wet cocoa beans. Thus, it can be concluded that the best drying using electric power can produce 812 grams of dry cocoa from 2000 grams of wet cocoa.

Bakso is a type of chicken meat ball that is commonly found in Indonesian cuisine. Currently, chicken meatballs are one of the processed chicken meat products that have a particular taste. The biggest energy contribution comes from protein, which reaches 60 percent, followed by fat as much as 38% and carbohydrates as much as 2%. The high public demand for processed products such as chicken meatballs has resulted in most shops, from stalls, school canteens, grocery stores, to supermarkets selling chicken meatballs. Before the existence of modern meat grinding machines, the process of grinding chicken meat was very difficult, but now, with advances in technology, there are many grinding machines on the market that simplify the process of grinding meat. The business of making and selling chicken meatballs has attracted the interest of several community business groups with small and medium scale businesses. In order for the business of producing and selling chicken to meet public demand both in terms of quantity and in terms of quality, good planning and management is needed. The design method used includes grinding machine product design. The result of the design that has been done is the output diameter of the meat with a size of 5 mm with the appropriate results (fine on average). Where the diameter of 2 mm and 3 mm produces chicken meat that comes out very slowly and is very smooth and causes the meat to melt and the chicken meat comes out fast and smooth. Thus, it can be concluded that a chicken meat grinder machine can grind 1 kg of chicken meat in 1 minute and the appropriate output hole size is 5 mm with a smooth and fast output of chicken meat.

Sosialisasi Pentingnya Air Bersih, dimana air bersih merupakan salah satu kebutuhan masyarakat yang menunjang kehidupan suatu komunitas. penyediaan air bersih berkaitan erat dengan status kebersihan dan kesehatan setiap individu dalam masyarakat. Kegiatan sosialisasi ini ditujukan pada masyarakat Desa Mbinanga untuk memberikan edukasi tentang pentingnya penggunaan air yang bersih dalam kehidupan sehari-hari. Maksud dari kegiatan ini adalah untuk memberikan pengetahuan pada masyarakat setempat tentang pentingnya penggunaan air bersih dalam kegaitan sehari-hari. Metode yang digunakan dalam kegiatan ini adalah sosialisasi.Masyarakat Desa Mbinanga sangat membutuhkan sentuhan nyata untuk dapat menerima manfaat secara langsung dari adanya sarana air bersih di lokasi mereka bertempat tinggal. Selama ini masyarakat harus berjalan jauh dari atas bukit ke lembah atau desa tetangga mereka yang berjarak sekitar 1-1,5 Kilometer dari desa mereka. Sehingga hal ini sangat memberatkan dan tidak efektif serta efisien baik dalam waktu, tenaga dan biaya. Sosialisasi Sehingga dengan adanya sosialisasi ini diharapkan ada tindakan secara langsung kepada masyarakat. Pengabdian ini dapat meningkatkan pengetahuan masyarakat tentang pentingnya air bersih. Masyarakat mampu menyediakan air bersihnya dengan bergotong royong dan bekerjasama dengan pihak luar sebagai penyokong dana untuk keperluan material pembangunan. Perlunya kerjasama lintas sektoral baik masyarakat, swasta, keagamaan dengan pemerintah agar terjadi sinergi yang positif secara terintegrasi sehingga manfaatnya lebih luas ke seluruh desa. Mengingat air bersih merupakan hak dan kebutuhan seluruh warga desa.

The main problem that is often found in the failure of microalgae production is poor water quality during the maintenance period. One of the causes of deteriorating water quality is the lack of oxygen which endangers microalgae which can inhibit cell growth so that it can reduce its productivity. On this basis, efforts are needed to refresh the water or aeration to help increase the dissolved oxygen (DO) level in the microalgae growth container using a paddle wheel. The development of an aerator blade design that has optimum efficiency is needed to reduce high electricity consumption and see more effective cell growth. For these problems, in this study, variations of the paddle wheel will be analyzed. Variations in the shape of the wheel used, namely straight and curved with the available aerators, are expected to have an optimum speed, area coverage and increase the amount of dissolved oxygen (DO). The method used is the experimental method . Based on this research, it was found that an increase in the value of cell growth occurred in variations in the shape of a straight paddle wheel of 122 cells/ml .
