Abstract

The main ingredient in the making of Tempe in addition to soy beans is the yeast Tempe. The role of Tempe yeast is veryimportant because the main factor that supports the success of tempeh is optimal yeast levels of the Tempe. In addition, theyeast levels of Tempe can also affect the duration of fermentation. If the level of yeast Tempe and fermentation time can beoptimal then the fermentation process can run well, so it will produce good quality Tempe and decent for consumption.Based on these issues, the author devised an application system built using the Matlab software in which the authors of thisstudy used the fuzzy method and the Matlab GUI as the application's appearance.

PABAKU Stabat Vocational School is one of the Educational Institutions in the Stabat area that has an inventory of school goods, the principal is responsible for all access that occurs in schools regarding school inventory items. At SMK PABAKU Stabat, the processing of school inventory items is still done manually by recording books and stored in archive form. This manual recording and storage of data allows for errors in the process of recording goods data, such as; data loss, repeated logging, data retrieval that requires a longer time span. In overcoming this, the author wants to assist employees in making reports through an inventory information system that has been computerized and connected to the internet using the My SQL database.

Abstract

on the process, processed rice not only produces rice, but also produces several forms of waste such as husk ash, bran, and rice bran. Rice husk ash is a hard layer that includes kariopsis which consists of two halves called lemma and palea which are interconnected. From the remnants of the rice mill, it can also be used optimally as animal feed. Feed is a mixture of various kinds of organic materials given to livestock to meet the needs of nutrients needed for growth, development and reproduction. The problem faced by this team is how to determine animal feed from the rest of the rice mill. Based on these problems, the authors designed an application system that was built using Matlab software which combines fuzzy logic programs and Matlab GUI as the application display.

Abstract

Human resources or employees in a company organization are very important to support the progress and quality of the company in achieving its goals. Having employees with good performance in a company does not just come from the employees themselves but there must also be a role from the company. Providing rewards to employees is one factor that can be used as a basis for providing motivation to employees. Performance appraisal is a process of measuring the results of work provided by employees, where this assessment will later provide results on who the best employees have the best performance to get rewards from the company. The problem that often occurs is that selecting the best employees or evaluating employee performance is based on subjective factors, which of course is detrimental to other employees and also has an impact on the company. Decision Support System (DSS) is a process that is part of the information system. Where the decision support system will assist in the process of completing semi-structured data processing. The Weight Aggregate Sum Product Assessment (WASPAS) method is a method that can be used in making decisions that have many attributes or criteria or is also known as MCDM (Multi Criteria Decision Making). The method used in this research is the WASPAS method which can provide the best alternative results, namely alternative A6 with the name "Tian" with a Qi value = 0.9815 which was selected as the best employee

Abstract

Early childhood education (PAUD) has a very important role in the formation of children's character, because at this age, which is called the golden age, a child's abilities can still be directed and responsive in accepting and responding to their surroundings. Financial education needs to be introduced as early as possible so that children have the right knowledge to manage money well. The habit of saving in a piggy bank is also almost never found in this digital era. The implementation of Community Service activities by the Indonesian Institute of Technology (ITB Indonesia) Kabanjahe Branch campus entitled, "The Role of Financial Education Through Fairy Tales and Enjoying Saving in Piggy Banks (Case Study: Starkids Kabanjahe Integrated PAUD School)", aims to instill the importance of financial education from an early age. The method of implementing this community service is through fairy tales and saving in piggy banks to children at Starkids Kabanjahe Integrated PAUD. The results that can be achieved from the implementation of this community service are that all children at Starkids Kabanjahe Integrated PAUD feel enthusiastic and motivated to save in piggy banks and can understand the meaning of saving.

Abstract

The problem that often occurs at Drg. Nina Syafitri's practice is that the supplier selection process is still subjective, where in selecting the Drgug supplier you have to choose it manually and sometimes there are several obstacles that are often faced, namely when one supplier already matches the price desired by the owner of Drg. Nina's practice. Syafitri’s, with appropriate payment terms, but problems with speed in the delivery of goods or ordered goods damaged in transit. As well as slow claims of damaged goods not being handled properly, the number of goods not matching the order, and the expiry date being close. Therefore, there are so many suppliers offering dental medicines, so Drg. Nina Syafitri's practice must be more selective and careful in choosing the right supplier. The method used in making decisions on selecting the best dental medicine supplier is the Analytical Hierarchy Process (AHP). REFERENCES Anwar, S. K., Priyanto, A., & Ramdani, C. (2021).

Abstract

Village Fund Allocation in Jati Sari Village is a multi-criteria problem which includes quantitative and qualitative factors. Several criteria that influence the selection of Jati Sari Village in the Village Fund Allocation are quantitative and qualitative. This study aims to develop a Decision Support System (DSS) that utilizes the Analytical Hierarchy Process (AHP) method to determine optimal village fund allocation. The focus of the research will be on Jati Sari Village in Padang Tualang District, Langkat Regency. The research method will use a case study approach to explore the specific context of Jati Sari Village. Through a combination of qualitative analysis, based on the description, discussion and analysis carried out in the previous chapters, it can be concluded that in practice, village fund allocation in Jati Sari Village still uses manual methods which are prone to uncertainty and lack of accuracy.
