Abstract

Indonesia is an agrarian country, the lives of most of its people work in the field of agricultural products. The raw materials produced by the agricultural industry include cassava tubers. Cassava tubers are fermented with the help of yeast sown on the surface of yams that have been steamed to become a sweet tape. The problem felt by partners is the use of steaming tools for 5 hours for cassava capacity of 800 kg per day has the potential to cause steaming devices to leak and make production capacity not achieved. There was also a problem with stoves that were often dirty, resulting in red and uneven flames, which caused the steam process to take longer and waste energy. The steamer stand used so far is a brick that has the potential to make the steaming tool spill over and overturn and fly dust (unhygienic). In this case, we need a touch of technology for the steaming process to ensure the smooth production process continues to run according to production targets and is able to accelerate the process of steaming tape and hygienic. The application of appropriate technology with a steaming device with aluminum material with a thickness of 1 millimeter following a two-cast cast iron stove along with its iron stand is considered appropriate, efficient, and does not increase production costs that are too high to ensure a smooth production process. The target and output of this activity is the achievement of a production capacity of 800 kg per day and it is expected that the processing time for steaming cassava is shorter by the use of appropriate technology, a cast iron stove with two faucets and a metal stand.

Abstract

This research aims to analysis of the surface matrix of copper cable in jointing as the imfluence of increasing current and heating on fire experiment. The investigation makes it easier to observe parts of its material of the surface matrix changes of copper cable in jointing as increasing of heating. The study was observed the material surface of general requirements for electrical installations (PUIL) jointed cables and standard NYA ø 1.5 mm2 cables at current load of 50 A and 110A using HIROX digital microscope, XRF (X-ray fluorescence), Raman spectroscopy, and fluke infrared thermometer (FLIR). The results of the study were obtained that the PUILsample jointing heat cable reached of 201oC and 1087oC with heat standard cable of 25.6oC. The copper cable will melt when the cable reached in over heating of 1080oC that it caused the deformation of the cross-sectional area of the cable which are observed in changes in the surface matrix of the burned cable structure. This research can be used as scientific basic for inverstigating the caused of fires and the heat maximum application on the cables.
