This study aims to examine the performance of pico hydro scale cross flow water turbines using multilevel double penstock as a conductor of water flow. Multilevel double penstock is used to reduce the transportation process from highways that are affordable to four-wheeled vehicles / cars to the location of the installation of the turbine. This condition causes the need for small-scale water turbine designs with lightweight construction with a kock down system. Overall the picohidro scale turbine construction is needed relatively cheaper transportation costs, so that people who have not been reached by the PLN network can be touched by small and cheap electricity. Turbine construction data has a runner diameter of 170 mm, body dimensions 200 mm x 300 mm x 250 mm, frame 250 mm x 800 mm. Pool tando 600 mm x 1200 mm and penstock length 16m. The power produced is theoretically around 2500 watts, with a data flow of 50 liters / second and a water level of 8 m. 65% efficiency. The research method is analyzing the double penstock water flow, by making paralon pipes in stages, ranging from 5 incci diameter, 4 inches and 3 inches, flow analysis approach using a gradient line, where the incoming water velocity and water velocity come out until entering the transmitting pipe. The performance results of this turbine provide an average actual power of up to 2000 watts. The stability of the inlet water condition is used by the Tando pond as a water bath. If there is excess water in the sediment tank, the water gate is used out, where excess water will automatically flow into the exhaust channel.

The strength of the welding result is strongly influenced by several factors, one of which is the selection of high current. This study aims to determine the effect of high current of welding on the strength of low carbon steel welding joints. The process of welding the material uses the open V seam connection type. The variations of the high current used were 80 A, 100 A and 130 A. The specimen used was a carbon steel plate with code of 1.0038 with thickness of 8 mm and the electrode used was the E7018 electrode with diameter of 3.2 mm. The strength of the welding results is influenced by arc voltage, amount of current, welding speed, amount of penetration and electric polarity. Determination of the amount of current in metal joints using arc welding affects the work efficiency and welding materials. Based on the research, it was found that welding using high current of 100 ampere produced the highest tensile strength value of all test specimens that were given welding treatment and good penetration results.

The use of cooling media in post welding process will affect the tensile strength of a material. This study aims to determine how much the influence of using cooling media in post welding and which cooling media is appropriate to use. The process is done by comparing the tensile strength of each cooling media, namely the cooling media of water, air, and coolant. The use of cooling media is carried out after the welding process, until the material that is ready to be welded reaches room temperature. Based on the experiments that have been conducted, the use of post-welding cooling media affects the tensile strength of medium carbon steel with the highest effect on the water cooling media, then the coolant media, and the lowest is the air cooling media. Therefore, the choice of the use of cooling media significantly affects the tensile strength of medium carbon steel in the post-welding process.

Energy consumption of a building is one of the biggest sources of energy use today. Green Building Comitte Indonesia (GBCI) has launched a concept of energy consumption saving in a nationally standard building. Audit Building energy audit is the way to know how actual building energy consumption is and find alternative solution to decrease energy consumption in order to fulfill the energy saving building criteria. Two types of HVAC systems will be run in the EnergyPlus simulation, split AC and central AC. The previous research proved that central AC is better than split AC system for energy saving in the building with 20 floors. The simulation results show that by using a certain energy system, a more efficient energy system will be achieved and can still maintain the comfort of the room at a temperature of 24 °C and relative humidity according to the Green Building Indonesia standard reference.

Numerical analysis of flow characteristics of the oil-water mixture in stratified-annular horizontal pipe Erizon, Nelvi; Jasman, Jasman; Irzal, Irzal; Aldio, Muhammad Fikhri; Saputra, Aprizal; Tin, Chau Trung

The loss of oil fluid flow in the piping system in the petroleum industry due to friction is the cause of low efficiency. To reduce friction loss, the viscosity of petroleum can be lowered by adding water as a mixture. Actually, the flow loss in a piping system is influenced by several factors including flow pattern, fluid type, flow velocity, flow pressure and pipe diameter. This study aims to determine the effect of flow patterns on changes in velocity in the two-phase flow of oil and water in a piping system. This numerical analysis research was carried out using Fluent 6.2 software with variations in the velocity of the oil-water mixture: 0.2, 0.4 and 0.6 m/s. The simulation results show that the greatest pressure loss occurs at a fluid velocity of 0.6 m/s where the flow is stratified mixed. While the smallest pressure loss at a mixture velocity of 0.2 m/s when the flow is stratified smooth. From the results of the study, it can be concluded that the increase in fluid flow velocity has a positive correlation with the increase in the value of flow losses in the pipe.

Reconstruction of the road section uses the flexible pavement method where aggregate material is the main component of the structure. Choosing the right aggregate gradation and meeting the specification requirements will greatly determine the quality of the road. This research aims to determine the characteristics of aggregate gradation sourced from stock files and compare the results of aggregate gradation analysis of job mix design planning consultants. The method uses laboratory testing. Aggregate wear test results 2-3 = 5.36%, 1-2 = 6.14%. The absorption value of aggregate 2-3 = 0.87%, 1-2 = 1.79%, 0.5 - 1 = 1.80% and stone ash = 2.27%. Values of dry specific gravity, SSD specific gravity, and apparent specific gravity of aggregate 2-3 = 2.73, 2.69, 2.66, 1-2 = 2.72, 2.64, 2.62 0.5- 1 = 2.70, 2.62, 2.58, rock ash = 2, 53, 2.59, 2.69. These values meet the requirements of the 2018 Bina Marga specifications, 2nd revision. The comparison of the results of the field aggregate gradation test analysis with the results of the job mix design analysis is the same because the aggregates tested come from the same stock file. The results of the sieve analysis test showed that the coarse aggregate fineness modulus of 2-3, 1-2, and 0.5 - 1 did not meet the specification standards, while the fine aggregate for stone ash did. The value that does not meet is caused by not paying attention to the additional note that the coarse aggregate retained on the 1" sieve is ±6%.

The use of A36 plate in the construction sector is closely related to connecting or welding between metals because it is useful in assembling a product to lighten human work. Examples of the use of A36 plate in the construction sector can be seen in trellis workshops, where this plate is often used as a support or support in making a balcony or canopy. However, sometimes workers do not understand how strong the plate is after being treated with welding, often they just guess at the durability of the plate, so this can cause various kinds of losses. Starting from damage to work objects to causing work accidents that result in loss of life. Therefore, this research examines the effect of variations in current strength on bending strength. This test was carried out on A36 plate material which was subjected to welding effects with varying currents of 80A, 100A, 120A and 140A. and a bending test was carried out using the ASTM E190-14 test standard, the results of this test were that at a current of 80A the bending strength value was 161.173 N/〖mm〗^2. Current 100A with a value of 229.851 N/〖mm〗^2. Current 120A with a value of 270.374 N/〖mm〗^2. And a current of 140A with a value of 374.839 N/〖mm〗^2. The test object with a current strength of 140A is the test object that has the highest bending strength value.
