Decision Support System (DSS) as one of the disciplines related to decision making both by individuals and companies in general, has been widely applied in various fields such as health, education, energy and business. There are several choices of methods related to decision support systems that have been used globally. The selection of suppliers as one of the important agendas in a company requires a decision support system so that the selected supplier is the best according to the criteria set by the company. In this study several DSS methods are used to solve supplier selection problems. In addition, this study conducted a comparison of the three methods in the DSS, namely WSM, SAW and WP in the case of supplier selection. The main contribution of this article is to compare some DSS methods that have not been studied before. As a result, there are two of the three methods that have the same sequence of results, namely the SAW and WP methods. Where in both methods the A2 alternative has the highest value of 0.875 for SAW and 0.84 for WP results. While very different results are obtained using WSM calculations.

Suppliers are sources providing the first material where the chain of goods distribution will start. Nowadays, the method of making decisions on the supply of bamboo raw materials for UKM Karya Manunggal is by conventional (intuition), so that it is often inappropriate in selecting the suppliers. Along with the increasingly fierce level of competition in the field of bamboo furniture, Karya Manunggal needs to review the strategy in the competition and to evaluate the ability of suppliers who are the main raw material providers. Therefore, the authors conducted a study that can be used by companies to measure the weight of each supplier by applying the Analytic Network Process (ANP) method. The Analytic Network Process (ANP) method was used to determine the ratio of the inner dependence and the outer dependence and the feedback. There were 7 criteria which were divided into 14 sub criteria and 6 alternatives used in this study. The final result was Arista Bambu with a weight of 0.2327, followed by Pak Wagiyo with 0.2106, Pak Paimin with 0.1737, Pak Gianto with 0.1506, Pak Tofa with 0.1217, and Pak Manto with 0.1107 .

The air-zinc battery uses oxygen from the atmosphere to produce electrochemical energy. After opening the battery into the air, oxygen diffuses into the cell and is used as cathode reagent. The air passes through the cathode to the active surface of the interior cathode in contact with the electrolyte liquid, namely sea water. On the active surface, the air cathode catalytically encourages the reduction of oxygen in the electrolyte liquid. This study aims to determine the effect of zinc anode on air batteries that are in direct contact with activated carbon as a source of electrical energy and find out the influence of electrolyte of seawater as an alternative source of electrical energy in air batteries. The research method uses Volta cells. Other advantages are safety and ecological benefits and low energy costs, as well as maximum power capability on environmentally friendly tolerance. In this study four salinity salinity was used, namely salinity of 3.56%, salinity of 3.99%, salinity 4.60% and salinity 5.02%. The results obtained are the highest voltage 1.144 Volt and the highest current of 4.85 mA is found in salt water salinity 5.02%.

Lately, PLN as the state electricity company that supplmost of the electricity needs in Indonesia is being hit by a "trial" which is in a row with the burning of several Interbus Transformers (IBT) in several regions. This can be caused by the rupture of the bushing so that it triggers a short circuit and results in the burning of the transformer. However, so far the investigation of other causes has been minimal as well as the effect of the load which is primarily a nonlinear load. Electricity is a device / device that can function if it is electrified. The device / tool is used to convert electrical energy into other energy such as motion, heat, light and so on. Electricity load consists of linear load and non linear load. changes in the use of linear loads to non-linear loads, among others, from incandescent lamps to TL lamps, and many non-linear loads that are widely used such as the use of induction motors (motors used in water pumps, refrigerators, air conditioners, etc.), rectifiers, static power converter (rectifiers and or inverters), electronic ballasts cause harmonics. Harmonics are sinusoidal waves with frequencies which are round multiples of the fundamental frequency. Harmonics can affect the work function of the transformer, which causes more heating to the iron core, which causes an increase in loss. In this study, the losses will be tested if the load is linear and also if it is loaded with non-linear loads. The results showed that for small loads, the response of the two loads showed almost the same current. While for moderate loads there is a difference that has not been so large, and for large loads large currents indicated there are large differences. So that the copper losses and iron losses are greater when the load is large. Given copper losses there is a current flowing in the transformer winding and the presence of resistance in the winding (I2R1 + I2R2). so that the increase in load current will increase copper losses. So thereby increasing copper losses causes a decrease in transformer efficiency.
