Berdasarkan hasil observasi, SMK Teladan Batam belum memiliki sistem informasi dalam pengelohan data nilai siswa. Kendala yang sering ditemui dalam pengolahan data nilai siswa yang dilakukan dengan sistem lama sangatlah lambat, tidak efektif, dan mempersulit guru untuk melacak nilai siswa dan bahkan rentan terhadap hilangnya data rekapan nilai. Tujuan dari penelitian ini adalah untuk mengembangkan da membuat sistem informasi pengolahan data nilai siswa berbasis Web bagi SMK Teladan Batam agar mempermudah pengolahan data nilai siswa. Dalam membangun sistem informasi pengolahan data nilai siswa penulis memanfaatkan metode SDLC dengan model Waterfall dalam perancangan sistemnya dan menghasilkan sebuah sistem dengan interface yang sederhana serta dapat membantu memberikan informasi yang akurat dan terkini untuk pemrosesan data.</em></p> 2022-07-26T00:00:00+00:00 Copyright (c) 2022 Computer and Science Industrial Engineering (COMASIE) https://ejournal.upbatam.ac.id/index.php/comasiejournal/article/view/5594 PERANCANGAN MITIGASI RESIKO HUMAN ERROR AKTIVITAS MAINTENANCE PADA PT BATAM AERO TECHNIC 2022-07-21T05:09:19+00:00 Hendri Setiawan Hendrisetiawan6869@gmail.com Citra Asmarawati citraindah@puterabatam.ac.id <p><em>Potential errors can be avoided by controlling actions when carrying out maintenance with the aim of controlling work being a continuous corrective action.

Tires have a role that is so that the vehicle can move. Tires can also be used to reduce vibration caused by road irregularities, protecting the wheels in a vehicle from damaged or uneven roads. Some vehicle tires can be damaged or punctured if they hit a sharp object such as a nail or thorn. In addition to being exposed to sharp objects, vehicle tires can also thin out if the tires are used for very long time, so it can no longer be used on any vehicle. Therefore, vehicle tires that are not suitable for use can be reused by recycling, one example is being used as plant pots.

Human error that often occur in production activityes can harm thet company in achieving production effectivenes and eficiency. Therefore, it’s necesary to improve the performance of workers in order to reduce work error that often occur. Several methods for identifying human errors in clude the SHERPA and HEART methods. SHERPA is a qualitative human errors analysis method that uses task level as the basic input. HEART, on the other hand, is a quick, easy and accessible way to determine the risk of human error. PT Duta Logistik Asia is one of the companies that produces activated carbon in the city of Batam. The activated carbon process goes throuh several stages, namely the heating proces, the sieving process, and the packaging process. Based on the information obtained from the company, errors often occur when doing work which greatly affects the safety of workers and production output as a result of human error. Finding recommendations that are needed to reduce error in the activated carbon production proces using the SHERPA method are to carry out regular and thorough inspections and work on each process and provide periodic training to employees. The probability of error in every work activity in the activated carbon production process using the HEART method wherye the largest nominal human error probability value is 0.16. The process that may occur in human errors in the activated carbon production stage at PT Duta Logistik Asia is through the highest Human Error Probability (HEP) value of 0.544 which is found in the heating and packaging process of activated carbon.</em></p> 2022-07-26T00:00:00+00:00 Copyright (c) 2022 Computer and Science Industrial Engineering (COMASIE) https://ejournal.upbatam.ac.id/index.php/comasiejournal/article/view/5741 DECISION TREE TECHNIQUE DALAM MENENTUKAN PENERIMAAN KARYAWAN SUPER MARKET DI LOTTE GROSIR BATAM 2022-07-26T02:47:30+00:00 Mhd isrok aryanto pb16150046@upbatam.ac.id Erlin Elisa erlin.elisa@puterabatam.ac.id <p><em>The role of human resources in company activities is needed because they are the main factor in all of activities that will be carried out by the company to achieve its goals, both to gain profits and to maintain the company's business continuity.

At this time the problem that is being faced by the company when conducting the initial survey is that there are often cases where there is an imbalance between supply and demand for goods. The large number of buyers and the diversity of tastes in the goods they have makes it difficult for PT Batam Bangun Prathama to predict the best-selling items so that it cannot anticipate running out of these items by providing more stock than before. To overcome this, a prediction system is needed for the sale of goods that are most requested by consumers. This prediction will be useful to make it easier for the building stock provider at PT Batam Bangun Prathama in planning the supply of goods and informing the company about the products most purchased by consumers.
