Abstract

The most dominant water distribution system used is the preparation system, in which each system has its respective advantages and disadvantages, where the weakness of the piping system is the unavoidable pressure loss caused by the connection factor and the surface roughness of the material used. Head losses are a flow loss phenomenon within the piping system. Head losses overall on 12.1 m piping system, This value can be from the sum of head losses on the pipe diameter of 25.4 mm with a length of 3400 mm of 0.0786 m. Head losses on pipe diameter 19 mm with length 3800 mm at 1.52 m and head losses at pipe diameter 12,7 mm with length 2800 mm equal to 10,59 m. The pressure in main pipe is 1,12 atm and pressure at output valve Water 1 atm based on the calculation method, the flow velocity in the main pipe 1 m/s, the speed in the second pipe 1.76 m/s, the speed in the last pipe of 3.34 m/s. Pipe used is PVC with diameter 1 inch, ¾ inch, and ½ inch. While the model pipe flow expert program 5.12 pressure on the main pipe of 1.18 atm, the pressure at the end of the valve 1 atm, the speed in the main pipe 1.077 m/s, the speed in the second pipe of 1.79 m/s, and the speed In the last pipe 3.3 m/s. The difference in velocity between modeling and calculation is due to the difference in internal diameter of the model by calculation, where the difference in value is 0.2 mm. The water debit generated from the test equipment is 1.3 m3/h, while using the software of 1.8 m3/h. The difference between the results of the experiment and modeling if the percentage of 270/0 is suppressed.

Abstract

The  objective of this study is to study the influence of  anode-cathode displacement to corrosion potential distribution of reinforced concrete cathodic protection system. Reinforced concrete speciments with a length of 1000 mm, width of 100 mm, and a height of 100 mm were used. Three variations of anode-cathode displacement for the specimens were 5 mm, 10 mm, and 20 mm. Specimens were immersed in a solution of NaCl 3.5 % and treated by wet-dry cycle. Profometer 5 + was used to find the location of reinforcement without damaging the surface of the concrete. Half-cell potential digital meters was used to measure the corrosion potential value of steel reinforcement. The corrosion potential measurements after 12 weeks of wet-dry cycle shows that the most negative corrosion potential was obtained for 10 mm anode-cathode displacement, i.e-391 mV. While for 5 mm and 20 mm anode-cathode displacements were -374 mV and -378 mV. Therefore, the anode-cathode displacements might affect the distribution of corrosion potential on reinforced concrete cathodic protection system.

Abstract

Cocoa one of the agricultural commodity which grow well that in Aceh and could producing the fruit for the rest of the year. In 2017, the wide of productive area reached 98,233 hectares (HA). The result of the crop was capable attained 32,403 tons/year. However, due to Aceh has climate tropical, when the dry season came, the drying process was still could on processing but when rainy season came, the drying process will be hampered and if the weather was still not sunny probaly it could make the fungus appeared. The aim of the research was to get the more optimal drying system so that it could be used when it was dry or rainy. The research described about drying system with 3 drying methods that is solar collector dryer, combustion dryer and hybrid dryer. From the result which conducted on 16 kg using a solar collector, the drying time was 25 hours with total energy used was 23.491,01 Kj. On the trial used hybrid energy, the drying time was 19 hours which total energy used was 160.636,19 Kj. On the trial used combustion energy, the drying time reached 14 hour with total energy used was 184.546,58 kj. in concluions that hybrid energy could get the best result in colour, kakao aromatic that more scents, no fungus, and the the seed could not break so that it reach I SNI quality.

Abstract

Machining technology, especially for micro hole cutting cases is a challenge in the industrial world to supply for components that have micro dimensions. The purpose of this study was to measure dimensional accuracy (roundness) and burr formation in the part of the entrance and exit holes. The object of the material used is brass plate. Brass plates with a thickness of 0.5 mm will be drilled using a twist drill chisel 0.2 mm diameter made from tungsten carbide material. Spindle rotation speed varied is 14,000 rpm, 17,000 rpm, and 20,000 rpm. The variation in feed rate for each spindle rotation is 5 mm / min, 8 mm / min, and 10 mm / min. The hole from the results will be observed and measured using a stereo microscope. From the measurement results show that the size of the largest hole dimensions with a value of 0.217 mm is formed at a rotation of 14,000 rpm and a feed rate of 5 mm / min, while the smallest hole diameter with a value of 0.202 mm is formed at a rotation of 20,000 rpm and a feed rate of 10 mm / min. The highest entrance burr value of 0.050 mm was formed at a rotation of 17,000 rpm and a feed rate of 10 mm / min, while the lowest height of 0.038 mm occurred at a rotation of 14,000 rpm and a feed rate of 5 mm / min. The highest exit burr value of 0.077 mm was formed at a rotation of 17,000 rpm and a feed rate of 10 mm / min, while the lowest height of 0.032 mm was formed at a rotation of 14,000 rpm and a feed rate of 5 mm / min. The results of this research data conclude that the accuracy of the hole dimensions and burr formation becomes better as the spindle rotation value and machining feed rate increase.

Abstract

Solar power generation is a power plant that utilizes solar energy as a source of electrical energy. Electrical energy in Sabang Weh Island is currently supplied by the power plant so it needs alternative energy to increase the electricity supply. The data taken in the form of sunlight intensity, voltage and current values generated from solar panels. Three points of data collection are: Banda Aceh, Kilometers zero Sabang and BMKG data Sabang Weh Island. The highest light intensity obtained on Sabang Weh Island for 853.20 watts / m2, the highest current of 4.32 Amper and a voltage value of 17, 20 Volt
