Electrical energy has become a basic need for humans today, almost all aspects of human life require electrical energy. The electrical energy needed so far has been produced from fossil energy which is not environmentally friendly and has dwindling reserves, alternative energy is needed which is environmentally friendly and sustainable. Energy that can be utilized includes water energy, wind energy, solar energy and so on. The sun is one of the abundant energy, by crossing the equator, Indonesia has enormous energy reserves. This potential is expected to become Indonesia's future energy. Currently solar cell technology is very advanced with increasingly good efficiency, in addition to energy conversion by solar cells with photovoltaic technology, a method is needed to store the results of the conversion into storage (batteries) optimally. One of the battery charging technologies is the Pulse Width Modulation (PWM) method, with this method battery charging is optimal on a 50 WP solar panel. In this study, a 50 WP solar panel was used, a 28 Ah 12 Volt battery, a 10 Watt Dc 12 Volt load and a 10 Ampere PWM Solar Charger Controller (SCC). The system was running for 3 months from September to December, the load was turned on for 12 hours every day with a load absorption current of 0.9 Amperes. Every day the current used is 10.8 Amperes. For 3 months the weather was not always stable, so charging was less than optimal, but until now the system is running well with an average after usage voltage of 12.3 Volts.

Sustainable regional development aims to increase regional competitiveness, increase economic growth, reduce regional inequality, and improve people's lives. South Sumatra Province is one of the provinces in Indonesia with excellent coal mining potential and can encourage sustainable regional development. The development of a sector cannot be separated from the support of other sectors, so optimizing the allocation of routine and development budgets into the economic sector is essential. For this reason, it is necessary to calculate the output impact analysis and analysis of the impact of gross value added on government expenditure using the input-output model. The calculation through this input-output model shows how much influence the increase or decrease in output and gross value added has on government expenditure. The role of the coal mining sector with other sectors and the condition of its existence in the economy need to be studied using the input-output table to determine the part of the mining sector in the regional economy. It can be concluded that the coal mining sector is still one of the leading sectors in economic growth in South Sumatra Province.

Waste in the form of garbage in the Piyungan area, Bantul Regency, consists of organic and non-organic waste, currently the condition is increasingly worrying because the landfills are very limited, so waste management must be managed optimally. To reduce the accumulation of excessive waste, a waste-cutting machine is needed. An efficient waste-cutting machine requires the right knife by choosing a knife between the crusher and shredder types. The selection of one of the blades used in the waste-cutting machine requires a design analysis using FEA (Finite Element Analysis) calculations and simulation assistance. Based on the results of the analysis of the calculation of the crusher-type knife using 4 blades, the required power is 2 HP, costs 8.8 million rupiahs and, the results of the FEA allowable stress test are 3.19E + 04, and 2.5 E + 08 are safe. While the Shredder type blade uses 13 blades, the required power is 2 HP, which costs 9.8 million rupiah and the FEA allowable stress test results are 1.53E+04 and 2.5E+08 safe. The results of the analysis obtained are that the selected crusher-type knife can be recommended for use in the design of a waste chopping machine because the manufacturing cost is 8.8 million and the Allowable stress is 3.19E+04,

Sri Rejeki bakery is one of the home industries in Bandung Regency which has been established since 1986 until now and produces various types of bread with one shift of 7 employees, and above average working hours of 11 hours. It is known that the actual conditions in the company are not optimal because the workload is not evenly distributed at each work station, this causes many complaints from employees that lead to high workloads. Based on these problems, if not resolved, these problems can affect the employees physically and psychologically and can reduce factory productivity. Therefore, this research was conducted by analyzing the workload of employees to determine the number of employees so that work can be more effective and efficient. Workload analysis problem solving in this study uses the Full time Equivalent method. From the results of the full time equivalent calculation analysis, the workload values for the dough, molding, baking and packaging work stations were 125%, 133%, 122%, and 151%, respectively. A total of 2 employees in the Normal category (FTE 1-1.28) and 5 workers in the overload category (FTE> 1.28). So the company needs to add employees, 1 employee in the molding work unit and 1 employee in the packaging unit. The addition of 2 employees will make the average workload normal value between the FTE index 1-1.28.
Sri Rejeki面包店是万隆县的本土产业之一，自1986年成立至今，生产各种类型的面包，一班7名员工，工作时间高于平均水平11小时。众所周知，公司的实际情况并不理想，因为每个工作站的工作量分布不均匀，这导致了员工的许多投诉，导致工作量很大。基于这些问题，如果不加以解决，这些问题会影响员工的身体和心理，并会降低工厂的生产力。因此，本研究通过分析员工的工作量来确定员工的数量，从而使工作更加有效和高效。在本研究中，工作量分析问题的解决采用了全职等效方法。根据全职等效计算分析的结果，面团、成型、烘焙和包装工作站的工作量值分别为125%、133%、122%和151%。共有2名员工属于正常类别（FTE 1-1.28），5名员工属于超负荷类别（FTE>1.28）。因此，公司需要增加员工，1名员工在成型工作单元，1名人员在包装单元。增加2名员工将使FTE指数1-1.28之间的平均工作量正常值。

Absorption was a separation process between gas fluids using liquid fluid media. The glycol contactor aims to separate the water content contained in the gas using tri-ethylene glycol media with process conditions at a pressure of 795-810 psi and a temperature of 85-110 o F. The contact process between fluids is assisted by the Intalox Saddle type packing which aims to maximize the contact process between fluids and it is hoped that the absorption process that occurs can be maximized. Tri-ethylene glycol which has absorbed the water content in the gas is regenerated in the glycol burner. This analysis used 4 packing variables (Raschig Rings, Pall Rings Plastic, Berl Saddles Ceramic, and Intalox Saddles Ceramic), 5 flow rate variables (1600, 1800, 2000, 2200, and 2400 BPD) and this analysis use the Hysys simulation program. Based on these variables, the absorption efficiency analysis results are obtained in the range of 93-94%, and the flooding percentage is 21-36%. It can be concluded that the type of packing is very influential on the percentage of flooding. Pall Ring Plastic was the type of packing with the lowest flooding percentage. According to research, lower flow rates increase the efficiency of H 2 O absorption.
吸收是使用液体流体介质在气体流体之间进行分离的过程。乙二醇接触器旨在使用三乙二醇介质，在795-810psi的压力和85-110°F的温度下，在工艺条件下分离气体中所含的水。流体之间的接触过程由Intalox鞍式填料辅助，该填料旨在最大限度地提高流体之间的联系过程，并希望发生的吸收过程能够最大化。吸收了气体中水分的三乙二醇在乙二醇燃烧器中再生。该分析使用了4个填料变量（Raschig环、Pall环塑料、Berl鞍陶瓷和Intalox鞍陶瓷）、5个流速变量（1600180020002200和2400BPD），该分析使用Hysys模拟程序。基于这些变量，吸收效率分析结果在93-94%的范围内，驱油率为21-36%。可以得出的结论是，填料的类型对水淹百分比有很大影响。Pall Ring Plastic是浸水率最低的填料类型。根据研究，较低的流速可以提高H2 O的吸收效率。

The glycol contactor aims to separate the water content contained in the gas using tri-ethylene glycol media with process conditions at a pressure of 795-810 psi and a temperature of 85-110 o F. The contact process between fluids is assisted by the Intalox Saddle type packing which aims to maximize the contact process between fluids and it is hoped that the absorption process that occurs can be maximized. Tri-ethylene glycol which has absorbed the water content in the gas is regenerated in the glycol burner. This analysis used 4 packing variables (Raschig Rings, Pall Rings Plastic, Berl Saddles Ceramic, and Intalox Saddles Ceramic), 5 flow rate variables (1600, 1800, 2000, 2200, and 2400 BPD) and this analysis use the Hysys simulation program.

Boil Off Gas (BOG) is formed as a result of the evaporation of liquefied gas at atmospheric pressure as a result of the expansion of the cargo space such as a tank which can endanger the condition of the tank if it exceeds the pressure design on the tank. So, to maintain pressure in safe conditions, the BOG usually has to be burned and directed to the flare. In another word, the factory has been wasting clean gas for free. So there is a better option to use a compressor for fuel-to-plant operation. Compressor K-6801 is a centrifugal type compressor with a single casing multi-stage compressor, with a prime mover or drive in the form of an electric motor. The BOG compressor functions to compress/drain the evaporation gases (Boil Off Gas) from the LNG tank to the PLTMG and the fuel system, while the excess output from the compressor BOG will be flowed to the booster compressor to flow along with the output from the ORV to the ARBEL (Arun-Belawan) gas network. The output BOG from the LNG tank will enter the compressor suction with a temperature of -145.5 °C and a pressure of 0.00054 kg/cm2G, where it will then come out of the discharge of the BOG compressor with ambient temperature conditions of 51.6 °C and a pressure of 15.4 kg/cm2G. After manual calculations, there was a decrease in efficiency by 13% from 98% of the design data to 85%, and a decrease in efficiency through Hysys by 21% to 77%.
