Authors: Zuhria Faida , Abukasim Sudarto M. 
Published: December 2019

Abstract
Indonesia is located at the equator line with its tropical climate which allows many species of plants to grow lushly. One of these species of plants is cassava which can be found from the west to the east of Indonesia. Cassava can produce amylum which can be turned into glucose through hydrolysis process. This research aims at figuring out the comparison of reaction times, i.e.: 12, 24, 36, 48, and 60 hours, comparison of substrate concentration, i.e.: 20:120, 20:140, 20:160, 20:180, and 20:200 gr/ml and comparison of yeast content: 5%, 10%, 15%, 20%, and 25%. The hydrolysis is performed by mixing the cassava starch pulp at 20 grams and yeast at 11.6 grams. Later, it is fermented for variable times. After obtaining the optimal hydrolysis time, i.e. 12 hours, a hydrolysis is done at variable substrate concentrations for 12 hours and an optimum sugar level is obtained at 20:120 gr/ml ratio. It is then hydrolyzed for 12 hours at substrate concentration 20:120 gr/ml ratio, hence the optimum reduction sugar level is obtained when the yeast content is 10% of the tapioca flour pulp weight.

Authors: Mashudi Imam , Agus Hardjito  , Pondi Udianto  
Published: December 2019

Abstract
Many studies have been done as hole flanges have important functional elements in many lightweight construction parts such as to provide sufficient fastening area, stiffness, bearing support, and allow for positioning, etc. Advancement of CAD/CAM software integrated to CNC machines technology has opened a new technology to enable pre-cut hole on sheet metal formed incrementally into required flange profile and height on its periphery known as incremental hole-flanging (IHF). Unlike conventional hole-flanging, the forming of the flange in the IHF process was using a simple tool pressed incrementally into a pre-cut hole with motion path performed by the NC programs on CNC machine. Hence, low volume production and rapid prototyping to reduce initial cost can be achieved to meet today’s production flexibility. There have not been many types of research to study the forming of flanges in incremental backward hole-flanging (IBHF) of closed or semi-closed profiles. By employing full factorial experimental design, this research focused on whether curved shoulder flange forming tool, process variables, and tool geometry of IBHF on copper plate through a spiral tool path strategy affect the produced flange height. The research yielded the results that the curved shoulder flange forming tool was successfully produced flange height through the spiral path strategy. From the data processing, it is shown that the variable of horizontally forming step, the forming rate, the forming tool rotation, and the tool shoulder radius significantly affects the flange height resulted from the IBHF process.
Performance Analysis Of Grid Tie Inverter With Power Limiter To Increase Utility Power Reduction In One Way kWh Meter Circuit
Authors: Prajogo Sapto , Santoso Budi Hartono 
Published: December 2019

Abstract
The use of grid tie inverter (GTI) in household electricity is intended to reduce the use of electricity from utilities. The configuration of GTI usually does not use batteries and the excess power from PV will be sent to the grid so that it will substitute utility electricity with electricity from GTI. However, this can occur when follow net metering program by installing a export-import kwh meters (two-way kwh meter) or follow feed in tariff program. If the kwh meter used does not support this capability or not following both program, the electric power of GTI will not substitute power from the utility. GTI with power limiter allows the inverter to work like a GTI in general but does not send excess power to the utility. The excess power from PV can be stored into the battery so that when the power shortage of PV will be substituted with power stored in the battery is not from the utility. In this research, conducted a study of the performance of the GTI with a power limiter and compared it with the GTI without a power limiter that works on an electricity network. The results of the study show that the use of GTI with a power limiter can increase the reduction in power usage from utilities by up to 40%.

Abstract
This study aims to investigate the extent to which electrical stimulation affects the quality of native chicken meat. The study was designed using a complete randomized design with four treatments consisting of 20 Volts / 0 minutes (as controls), 20 Volts / 2 minutes, 20 Volts / 3 minutes and 20 Volts / 4 minutes. The parameters observed were shrinkage cooking shrinkage, meat pH, flavor, color, texture and tenderness. The results showed that physically stimulating electricity for two minutes significantly affected the lowest cooking shrinkage compared to the duration of stimulation compared to other stimulations. Electrical stimulation does not affect the pH of meat. The treatment of electrical stimulation significantly affected the organoleptic properties of chicken meat, where the flavor of the meat was favored by the panelists at three minutes of stimulation, as well as the aroma, texture and very apparent tenderness. Color parameters are not affected by electrical stimulation. It was concluded that the two to four minute electrical stimulation treatment with 20 Volt strength had a very significant effect (p <0.01) on cooking losses, tenderness and significantly affected (p <0.05) on taste, aroma and texture of native chicken meat.
