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> Mahardian Mahardian Mesri Silalahi Copyright (c) 2022 Computer and Science Industrial Engineering (COMASIE) 2022-07-26 2022-07-26 7 1 1 7 PERANCANGAN MITIGASI RESIKO HUMAN ERROR AKTIVITAS MAINTENANCE PADA PT BATAM AERO TECHNIC <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. The problem faced by the company is human negligence or human error in the maintenance painting process. The method used is FMEA (Failure Mode and Effect Analysis) by providing an assessment of risk and mitigation plans using QRA. (Quantitative Risk Analysis) covers all activities to identify hazardous events sequentially and the level of risk. The research was conducted on the process of repainting the aircraft body. The purpose of the study was to determine the negligence of technicians or human error in the process of repainting the aircraft body and the factors causing the problem. The results</em> <em>of the study describe that the frequency of failure of the Boeing 737-900 Series painting process with the type of reject dust is 31.25. The results of the FMEA analysis on the failure of the Boeing 737-900 Series painting process with factors caused by human error, namely lack of maintenance and cleaning of work equipment after use has an RPN value of 448.</em></p> Hendri Setiawan Citra Asmarawati Copyright (c) 2022 Computer and Science Industrial Engineering (COMASIE) 2022-07-26 2022-07-26 7 1 8 17 RANCANG BANGUN ALAT PENDETEKSI KEBAKARAN UNTUK TUNARUNGU BERBASIS ARDUINO <p><em>Fire is a disaster that causes material losses, but can take lives.

With a big motto in the global market, PT Waen Indonesia, of course, must have quality human resources. One of them is in improving employee performance, employee discipline, and employee loyalty to PT Waen Indonesia, then every year the leadership of PT Waen Indonesia gives bonuses to employees. PT Waen Indonesia has quite a lot of employees, so with the number of employees to be analyzed, a company leader must work hard in analyzing which employees are eligible to receive this annual bonus. The results of the decision tree that have been tested produce the highest gain value which is an important factor because it has a large enough influence in determining the annual bonus for PT Waen Indonesia employees, these factors come from the attributes of years of service, targets, and attendance.</em></p> Khe Ben Erlin Elisa Copyright (c) 2022 Computer and Science Industrial Engineering (COMASIE) 2022-07-26 2022-07-26 7 1 28 36 PERBAIKAN TATA LETAK PENYIMPANAN BARANG DI GUDANG PT STB <p><em>At this moment, garment care product in PT STB warehouse are not optimize as the part is not tidy up without considering part movement frequency, hence fast moving product have to pass several step to pull out.

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. Therefore, vehicle tires that are not suitable for use can be reused by recycling, one example is being used as plant pots. So with that, researchers will create a software that can explain a way to recycle vehicle tires into plant pots with software, namely Augmented Reality.

As an example of the large development of electronic device technology such as the Arduino Uno R3, one of the technological tools that is very simple and easy to operate in the form of making mini tools can be called a microcontroller which functions to process simple programs such as C++ programming and Arduino ID programming to drive a computer. The object that is connected to the Arduino Uno R3 to run perfectly also requires a PWM that can control a DC motor that can rotate left and right to rotate in the manufacture of shuffing dring drinks, which are better known as hot drinks, for example bandrek, the egg. The shuffing dring can also be referred to as a hot drink shaker, the existence of this shuffing dring drink can make it easier to manufacture so you don't have to wait a long time in making it, just enter the ingredients you want to eat in a short period of time, you can finish quickly how the arduino tool works. the code to pwm after that pwm itself drives the dc motor with the maximum possible rotation, it can also rotate in two directions in seconds so that the work is simpler to have two dc motors as drivers with the dc motor position from above rotating in two directions while the dc motor from below enough with one direction of rotation so that in the manufacturing process it is perfect.

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> Orianus Kristian Gea Sri Zetli Copyright (c) 2022 Computer and Science Industrial Engineering (COMASIE) 2022-07-26 2022-07-26 7 1 83 95 DECISION TREE TECHNIQUE DALAM MENENTUKAN PENERIMAAN KARYAWAN SUPER MARKET DI LOTTE GROSIR BATAM <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.

With 25 years of experience, PT Batam Bangun Prathama has been trusted by the Riau Islands community as a distributor of complete building and construction materials so that product standards cannot be doubted. 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.
