Business competition in the current era of globalization is very rapid, so it is increasing competition between companies which is getting higher and tighter. UD AMJ Jaya Teknik is a company in the field of turning and manufacturing spare parts. As long as the business run by UD AMJ Jaya Teknik experiences a decline in income, good and appropriate strategic management is needed for UD AMJ Jaya Teknik. The methods used in this research are the SWOT and QSPM methods. The aim of this research is to provide strategy suggestions for companies to experience increasingly rapid increases in income. The four stages carried out are the stage of looking for internal and external company factors, the IFE and EFE matrix stage, the SWOT matrix matching stage, the stage of determining the main strategy with the largest total attractive score using QSPM. There are 7 proposed marketing strategies for UD AMJ Jaya Teknik. Improving the quality of the products produced and innovating the products produced is the strategy with the highest TAS score of 5.95.

Inventory control is a company policy in managing goods in order to optimize the number of orders and minimize inventory costs. The object of this research is PT XYZ in Gresik city which produces tempeh and tofu. Several raw materials are needed in the production process, one of which is soybeans. As the main raw material for making tempeh and tofu, soybeans are perishable goods. Previously, the company used a method based on past usage data in controlling its inventory, resulting in bloated inventory costs and a buildup of raw materials in the warehouse. Therefore, researchers need a method that is economical and takes into account the limitations of the company. The Lagrange EOQ method is a model that measures the order quantity by looking at one or more restrictions. The results of the Lagrange EOQ method get an order quantity of 20 sacks of soybeans with an order frequency of 27 times a year, a total inventory cost of Rp. 665,575, an ROP of 12 sacks and a safety stock of 10 sacks.

Undervolt is a term that refers to a way to make a computer device run on lower electrical power than the manufacturer's provisions. To do undervolting requires a good experience for user and computer devices that are good or specialized for undervolt purposes such as processors. This study aims to find the optimal minimum voltage that the processor can use without causing performance degradation or instability, and temperature drops that the processor produces while it is running. In this study, the author tested a processor device with the type of AMD Ryzen that already supports the undervolting process from the factory. AMD Ryzen 3 2200G processor is one of the processors with 14nm fabrication, where this processor promises significant performance with the number of cores, memory chace capacity, and power efficiency. On this day, many games demand the use of an aggressive processor. Of course, this will consume power on a larger processor. The author conducted several test scenarios to get the best performance. It was found that the scenario with undervolt at 1.25V showed the best performance.

PT. Pertamina Geothermal Energy Area Lumut Balai has a very extreme work location with various contours, safety factors and lack of access to electricity for street lighting are things that need attention given the importance of street lighting in the company's operations. Street lighting is an important element that supports the comfort and safety of road users in their activities at night. The research objective is to design an IoT (Internet Of Things) system that can monitor the utilization of pipe heat into electrical energy for street lighting and provide street lighting needs around geothermal well pipes. In this study used thermoelectric as a tool to generate electrical energy from available heat. The IoT system is used to read data parameters as a tool to display temperature, voltage and current values on the LCD (Liquid Crystal Display) and the Thingspeak website. The temperature value is read by the MAX6675 thermocouple sensor while the INA219 sensor is used to read the voltage and current values. The focus of this research is to heat the thermoelectric so that it can produce electrical energy to turn on the lights as lighting and can monitor parameter data directly. The highest thermoelectric electrical energy output is at a temperature of 75.1˚C. Where at this temperature a voltage of 2.32 V is generated and a current of 0.03 A. The lamp will turn on if the thermoelectric heat is fulfilled. The light turns on when the environment is dark and the light turns off when the environment is bright

One of the uses of electricity that is widely used by society today is as a source of lighting. The increasing level of community mobility makes all activities require lighting. One part that is important and requires lighting is a highway or public road. PJU is a lighting lamp that is public (for the common good) and is usually installed on roads and certain places such as parks and other public places. PJU (street lighting) or road lighting is a light source that is installed as street lighting at night. Public street lighting using solar power is a cheap and economical alternative to be used as a source of lighting electricity because it uses a new and unlimited renewable energy source that comes from nature, namely solar energy. This study aims to determine the feasibility of solar street lighting in the future as a substitute for conventional public street lighting in the future by looking at the Net present cost, and Break even point assisted by HOMER software version 3.10.3. And the results obtained from the calculation of the Net present cost of conventional street lighting costs less, which is only Rp. 30,245,473 and the Net present cost of solar street lighting costs an initial investment of Rp. 128,341,312 and the BEP (Break even point) graph that has not been found to break even.

Sausage is a processed food product that is generally made of meat, fat, filler, water, binder and salt. Catfish is a source of animal protein that has advantages compared to other animal products, namely catfish which is rich in lysine, and leucine. Moringa leaf flour is Moringa leaves that are given drying, milling treatment to facilitate processing into various food products and as a fortification material with high nutrition. This study aims to determine the effect of differences in concentration of catfish: tapioca flour with the addition of Moringa leaf flour on the physicochemical properties of catfish sausage. The results obtained in the study that the difference in the concentration of catfish: tapioca flour and the addition of Moringa leaf flour affect the analysis of water content 58%; fat content 13%; ash content 1.85%; protein content 18.09%; color parameter L* 47,26-66,48; color parameter a* (-4.43)-5.40; color parameter b* 14.25-26.71.

Attendance management is a problem commonly faced by companies, management using a manual system still causes problems. The problem that is often faced is the difference in employee attendance data reports because they have not been well integrated. The purpose of this study was to design an employee attendance information system at PT. Kartika Utama Semarang. From the above problems, a system is needed to integrate these needs automatically and is managed entirely by a computer using an RFID system in it so that the leadership can monitor attendance and payroll in real time. The application of the author's research and development (R&D) research method in this study. This research resulted in an information system application to facilitate the management of attendance and payroll of PT. Kartika Utama Semarang
