Abstract

ABSTRACT An analysis of the strength of the material on the framework of the digital triaxial apparatus to increase the maximum working capability to 50 kN has been performed. A digital triaxial device is a test machine used to determine the properties of a soil sample. Analysis of the framework of this tool is needed to see the character of the material used so as to obtain maximum performance to support the performance of the digital triaxial device. The frame in question consists of a bottom base, two poles, and a beam rod positioned at the top of the pole. The analysis performed using 3D Solidworks software utilizes structural analysis features. Pressures of 50 kN are given in a vertical direction so as to press the midpoint of the bottom base and the beam rod, both of which are attached to the pole using a nut as anchoring. The analysis result shows that Stress Von Mises maximum vallue that works on parts is 1.664,7 kgf/cm2.

Abstract

The purpose of this study is to determine the effect of the addition of reflectors to increase energy production and simultaneously to determine the change in temperature of solar cell as a result of the addition of the quantity of incoming sunlight. Capacity of the solar cell module is approximately 50 Wp, where the test is done from 9 am to 3 pm for three days. The reflector's slope angle used is 1000, 1100, and 1200. The results of this study indicate an increase in output power of the solar cell module an average of 2.59% (with 4.42% at maximum).The side effect is the increase in maximum temperature of the solar cells by 0.60C (or 1.59%).

Abstract

The planning of the air system is intended to calculate the cooling load in the Hall of SMKN 1 Sekayu. So that before the AC was installed in the SMKN 1 Sekayu had an overview of the amount of AC capacity needed to condition the air in the hall with dimensions of 18 m x 16 m x 6 m. To obtain these results, the authors used the CLTD (Cooling Load Temperature Difference) calculation method based on ASHRAE GRP 158 Cooling Load Calculation Manual. Which consists of calculation of Extenal and Internal cooling loads. Calculation of cooling load based on primary and secondary data which then results are adjusted to the type of air system. After calculating the cooling load, the maximum load results are obtained at 237013,1917 Btu / hr, thus the AC capacity needed is 26 Pk with the Direct Refrigerant System, AC Floor Standing system.

Abstract

Modern Water Purifier uses the main drive, namely a water pump with a power of 15-30 watts, a voltage of 220 volts AC, a frequency of 60 hertz with an absolute pressure from the pump 10-100 psi (Pond Square In). The working principle of this equipment is the water pump as the main water drive or diverter that is connected with filters which then will flow through the hose which then comes out through holes (pores) that are on the sides of the filter. From the water that comes out it will go to the Reverse Osmosis (RO) membrane and then it will flow towards Bio Ceramics which will last through Post Carbon so that the water that comes out after the process will become water that can be consumed by humans. With the price of R ranging from 0 ÷ 1, it can be seen that water that has been processed with a yield of 0.9 can be said to be feasible to drink or contaminant substances in water are perfectly retained by the membrane.

Abstract

Water supply is a basic need for life. Water management that requires a large amount of cost and energy is needed alternative solutions to produce a cheap process. Research on the distillation process was carried out to find solutions to these problems. The research was carried out by a experiment method to produce a distillation process for water purification. The experiment use an effective fresnel lens of 0.785 m2 and the receiver volume was 200 mLThe results of the study explained that using a fresnel lens concentrator was able to generate steam. The steam can be condensed to produce fresh water. Data from calculation obtained average direct solar radiation is 531.98 Watts/m2 and the power received by the receiver is 346.61 Watt. The average normal solar radiation in tests is 515,7 W/m2. The average temperature of the focus point on the cone receiver is 520,4OC . The wet steam generation process is obtained when the water temperature in the receiver shows 95OC. Experiments of distillation for 200mL sea water needed 10 minutes to reach 4 bar of pressure. Steam is flowed into the condenser so that distilled water is obtained 150 ml.

Abstract

Modified Plate Liners on Air Chamber Pulverizers With Wear Plate Resistance Materials Arbex 400 can extend lifetime, facilitate plate liner replacement in pulverizers (a tool for grinding and smoothing coal) due to abrasion by phyrite stones (coal follow material) which is blown by primary air scrape the liner plate cause a leak in the body air chamber pulverizer, speed up maintenance time. Modification by changing the sheet plate design into segments, adding hardness from 359 HBN (Hard Brinel Number) to 400.63 HBN and increasing plate thickness from 12 mm to 30 mm. From the evaluation after surgery for 6 months it was found that the plate liner was able to survive ± for 24 months, which previously had 8 months of abraded condition, especially the bottom to the main body.

Abstract

Frequent complaints from workers in the company regarding the unavailability of hot water for bathing water needs during the rainy season. To fulfill hot water needs for company workers, it is necessary to install a water heater in each mess for comfort for workers. This experiment is also in line with supporting the Government and Company programs in terms of the efficiency of the energy and global warming beneficiaries that are currently happening. Water heater technology (WH) is considered the most recent and used as an alternative. Its main function is to supply hot water needs in all parts of the housing that are in need. The amount of heated water is adjusted to the needs of the dwelling whether it's for bathing, kitchen matters, and washing. Because it is used when needed, the efficiency side is greatly highlighted from the water heater product (WH). Another advantage of the product concerned is the unlimited supply of hot water provided there is always electricity available

Abstract

Stringent ventilation regulations make the humidity problem more serious. In modern society, people spend most of their time in built environments. More attention has been paid to indoor air quality and indoor thermal comfort. Fresh air centered HVAC systems are necessary for almost all buildings. In this chapter, a quantitative analysis is provided for the energy expenses and possible savings in fresh air ventilation. More specifically, hot and humid climates like Palembang are selected as the calculating sample. Under such climates, moisture recovery is more important than sensible recovery. Keywords: Humidity,Fresh Air, indoor thermal, HVAC, Palembang Society
