Abstract

One of the factors that affect the comfort of the learning process at school is students who violate school rules. To maintain school order, it is necessary to give punishment as stipulated in the school's decision. Decision Support System can be implemented as a media to support decision making in giving punishment to problematic students. In general, punishment for problematic students uses a point system according to the type of violation. However, the calculation and management process is still done conventionally which is prone to human error. Engineering punishment is very likely to occur due to the like and dislike factor. This of course causes the school's decision to be wrong. This study aims to make a Decision Support System application to determine the level of punishment for problematic students using the Simple Additive Weighting (SAW) method and the Decision Table. The weighting of violation points is based on three criteria, namely academic violations, aesthetic violations, and ethical violations. The results showed that the calculation of the weighted score of each type of student violation became more precise.

Abstract

One of the important things in financial management is financial services. Cilacap State Polytechnic (PNC) is a PTN as a Work Unit. Financial management at PNC refers to applicable government regulations, but financial service policies are the authority of the leadership as a strategy to create fast, effective, and accountable financial services. The budget usage policy stipulates that work units must propose budget usage based on the Fund Withdrawal Plan through a down payment form approved by the Financial Management Officer. The current problem is that down payment forms are often scattered or lost, so the response time for payments from finance is slow, and payment queues are often not in sequence. This results in activities being hampered. This research aims to create a prototype or development design for the Financial Services Information System at PNC. The FCFS method is used as a service scheduling algorithm based on arrival time to optimize financial services. In this way, the financial service process will be more organized, the response time for financial services will be faster, and the queue for service requests will be in line.

Abstract

Assets are resources owned by an entity. Cilacap State Polytechnic is a higher education institution that has many assets. Current asset maintenance and repair services are still carried out conventionally. Each work unit must fill out a maintenance and repair proposal form and then submit it to the Maintenance, Repair, and Maintenance Unit (UP3). The proposal will be recorded and scheduled to be followed up by the Technician. The problem that occurs is that the proposal form is often scattered and even lost so the response time is often slow. In addition, maintenance and repair schedules are often not ordered according to the time of the request. This has an impact on the abandonment of work in certain work units. The purpose of this research is to create an information system for the repair and maintenance of campus assets. In order for maintenance and repair services to be carried out according to the time of the request, the FCFS method is applied. Thus, the service process for maintaining and repairing campus assets becomes more organized, schedules (queues) are sequenced, and the response time for incident handling is faster.

Abstract

Tracer study is a method used by several Vocational High Schools (SMK) to collect alumni data and monitor alumni progress. The problem is in monitoring the alumni who do not only stay in Cilacap but outside of the city as well. Moreover, the data collection method is still simple by only using a questionnaire form filled out when they take their diplomas. This condition is less effective because many alumni are still looking for a job, therefore it is difficult to check up on them all the time. This study aims to create a tracer study application using the waterfall method. The testing phase uses the Blackbox testing method. Based on the test results, the application can make it easier for BKK administrators to collect alumni data and help monitor the alumni progress by checking the percentage of alumni status and making it easier for alumni to fill out questionnaires. The results of the overall usability test conducted on 30 respondents resulted in the predicate "Very Good" with an average of 85.51%.

Abstract

One source of regional income for Cilacap Regency is the management of vehicle parking lots. Currently, parking area management is carried out by recording the identity of the parking location based on the street name, while the withdrawal of parking fees is carried out by towing officers who come to the parking location and then record it in a book. The current management of parking lots is still inaccurate because there are several street names that have more than one parking area which results in data redundancy. The conventional parking fee collection system causes frequent discrepancies in reports due to the potential for misuse of parking fees. The absence of tools that can be used by related agencies to control reports is the cause of the problem. The research objective is to develop an information system by applying LBS technology which functions to detect parking points precisely and QR Code Detection which functions to detect the identity of parking attendants. System development uses the ADDIE model. The results of the research are an information system for mapping parking lots and picking up parking fees based on Andorid which can help manage vehicle parking lots which includes mapping the location of parking lots and picking up vehicle parking fees.

Abstract

Junk goods are no longer piles of worthless goods for businessmen who are keen to see the economic value by taking this opportunity by becoming a pelapak company to buy and sell junk goods purchased from collectors to be sold to buyers. The problems found with Pelapak include the manual recording of sales administration which has the potential to cause recording errors. Pelapak does not know for sure the stock of junk they own and those owned by collectors because the locations of the collectors are far apart. Orders of junk goods between pelapak and collectors are still via telephone so pelapak does not know which collectors are in the process of sending goods. Problems also occur on the part of collectors including unprofessional sales transactions. Based on these problems, a used goods stock management system is needed using the Economic Order Quantity (EOQ) method. The purpose of this study is to build a used goods stock management information system that can monitor the availability of used goods owned by collectors and pelapak. System development uses the prototype method and designs with concepts. The results of the research are that the system created can help find out the stock and the amount in each collector, recap sales reports, provide accurate information, facilitate business transactions and fulfill sales targets to buyers.
