Currently Indonesia fave crucial issues in energy sector, which are the high growth of energy consumption but low on utilization efficiency and the domination of fossil fuel energy. Inefficiency of energy consumption shown by the very high energy intensity value. Energy diversification from fossil fuel to renewable energy and energy conservation are the effort that have been done lately. Indonesian topography and geographical climate have great potential for water resources development and utilization. Based on that potential, if the natural resources exploitation such as deforestation on the river basin area increases. It will gives negative effect to the river basin hydrological condition, such as peak debit increasement, inter climate debit fluctuation, surface stream coefficient, flood and drought, etc. This research conducted on sub-river basin Siau River.

Forehand smash is one of the techniques that every badminton athlete must master well. To do this stroke well, a good movement pattern is needed, biomotor maturity which in this study is related to the age of the athlete. So that the development of age will cause differences in movement patterns which in this study analyzes the forehand smash movement patterns in badminton based on age. It is known that the most efficient badminton technique for gaining points in badminton is the smash. The smash-hit is more likely to produce a fast shuttle lock rate performed using the forehand smash technique. So that in this study the writer will analyze a technique in badminton, namely the forehand smash technique. These findings contribute to future research on the biomechanical analysis of forehand smash motion in badminton.

This porous electrode composite is prepared by sonication and chemical exfoliation assisted by acid. Synthesis of supercapacitor is also added by glucose, which acts as a spacer between layers of rGO to increase the capacitance, also as binder between the materials used. Combining Fe3+ with old coconut shell rGO give high specific capacitance of up to 99 F/g at a potential window of -1 V to 1 V. The Fe3+/glucose/rGO electrode has thickness of up to 57 nm (from PSA result) and give a uniform distribution from EDX mapping with disperse Fe domains and not bonding with rGO.For the goal of large, environmental - friendly, renewable, and inexpensive energy storage, the development of supercapacitor electrodes is needed, by anchoring transition metal oxide (Fe3+ ion) as pseudo capacitor electrode material with reduced graphene oxide (rGO) from an old coconut shell as electrochemical double layer capacitor (EDLC).

This research aims to analyze the types of defects that occur in products, identify factors that cause defects in products using Cause and Effect Diagrams and identify suggestions for quality improvement actions that can reduce defects in the product. In the production area there are many types of defects but there are 3 biggest types of defects (Black Crest, Chatter and Chip) which are analyzed to reduce to keep product quality improving. This study uses a tool from FMEA (Failure Mode Effect and Analyze) to summarize rejected items into priority and Squareness, Histogram, Pareto as quality tools to count and determine all rejected items. The level and value of the results of the RPN study decreased from Low to Very Low starting from the risks: Black Crest defect for the risk of excessive ovality pipe dimensions from RPN 135 with a low level to RPN 27 with a very low level, for the risk of Squareness at the end of the oblique pipe from RPN 135 with a low level becomes RPN 81 with a very low level, for the risk of swaging results on imperfect pipe from RPN 243 with low level to RPN 81 with very low level. Chatter's defect is for the risk of the blunt insertion of RPN 243 with a low level to RPN 27 with a very low level, for the risk of corrugated pipe during processing from RPN 243 with a low level to RPN 81 with a very low level, for the risk of material being difficult to roll from RPN 405 with a low level to RPN 45 with a very low level. Chip defects for risk The machining program is not designed to cut Chips from RPN 243 with a low level to RPN 81 with a very low level, for the risk of glass on the machine that is not clear when the screwing process of RPN 243 with a low level becomes RPN 81 with a very low level , for the risk that the operator does not withdraw the Chip during the rolling process from RPN 243 with a low level to RPN 45 with a very low level
