Abstract

Pateh and Wates Kaja hamlets are located on the hillside slopes. 180 family heads mostly live fromagriculture. Unavailability of clean water in both villages, low public awareness on health and environmentalhygiene, low community productivity, waterfall Jaga Satru not yet organized and published as a touristattraction, the selling rate of salak Bali is low. Program achievements is, increasing public health withadequate clean water, cleanliness of the environment and counseling clean and healthy lifestyle. Increasepublic knowledge with the availability of reading books and the reading room facilities. Increasedcommunity productivity. Cost efficiency through assistance and introduction of hydram pump technology.Results of Activities is clean water system in Pateh hamlet with hydram pump method has been realized, theevaluation results show the amount of water that is compiled to the location of 43,200 liters / day. Everyperson needs water every day 80 liters / day then enough for 540 people or 108 families. Clean water systemgravity method in Wates Kaja hamlet has been done well and water distribution more evenly. Livestock health services achievement of 30 cattle. Reforestation of 100 coconut tree daksina has been done in thewaterfall environment. Publication activity Jaga Satru waterfall tour with balihoo method has been done andforeign tourist visits have increased by 100%. Environmental hygiene activities featuring 3 pieces of wastebins to collect inorganic waste. Making Master Plant tour waterfall keep 100% done.

Abstract

Phase change material (PCM) is a material that can absorb and store energy and can release it based on the principle of latent heat energy storage. Beef tallow is one of the materials that can be used as PCM but its low thermal conductivity is around 0.181 W/mK. Hence, thermal conductivity is considered an important factor in the conduction heat transfer.  This further affects kinetic absorption and heat release. However it is possible to increase the values by adding another material that has a high thermal conductivity. The purpose of this study is to elevate the thermal conductivity of beef tallow by adding rice husk char. This research involves direct incorporation method, where beef tallow is thawed and mixed with the rice husk char then stirred with a rotation of 100 rpm until the mixture becomes solid. Addition of rice husk char with weight fractions of 5 and 10% and grain size of 0.045 mm. Subsequently, thermal conductivity test was performed using the TQ Heat Transfer Experiment Base Unit.The results show that with the addition of rice husk can increase the thermal conductivity of PCM beef tallow. The increase obtained in the addition of 10% rice husk char is 37 times compared to the pure sample. Based on this result it is concluded that carbon-based materials such as rice husk char can be used to increase the thermal conductivity of PCM materials.

Abstract

Abon is one of the people's favorite menus made from shredded chicken or beef. This reality has led to the development of many shredded products with various raw materials, such as shredded eel, shredded fish, shredded shrimp, shredded catfish, and even shredded eggs. The model for develo ping shredded eggs from egg raw materials was eyed by a women's business group in Baluk village, Negara sub - district, Jembrana district. The business group in question is the Women Farmers Group (KWT) Pitik Jaya, which began in 2014 by experimenting with their unique product, shredded eggs. The business of making shredded eggs is actually quite prospective because the egg raw materials are produced by the KWT itself. However, this group has problems related to productivity and efficiency, namely in the process of draining shredded oil which is still conventionally done by simply placing shredded coconut on aerated niru. Efforts to overcome the existing problems are carried out by replacing conventional equipment with spinner machines. This machine is multi-functional and is built by a dedicated team so that it can also be used for other product oil extraction. The result of the activity was that the team succeeded in designing and manufacturing a multi-function shredded oil spinner machine with a capacity of 420 eggs per day, so that the use of this machine increased the quality of shredded eggs produced by KWT Pitik Jaya and increased productivity by up to 450%.
