Abstract

Research by developing an information system is a research that aims to produce and develop an information service system design in the form of website-based rooms lending using PHP as a programming language and MySQL as a database that will be used at the Faculty of Teacher Training and Education, Sultan Ageng Tirtayasa University in-room management as room loan, room loan schedule, room loan data, and room information. This study uses the waterfall development model, with 5 (five) stages of development including the stages of communication, planning, modelling, construction and deployment. This research used Alpha and Beta testing to 3 (three) media experts and 31 (thirty-one) users including 1 (one) admin and 30 (thirty) students. Data collection techniques using interview techniques, observation and dissemination of research instruments. With data analysis in the form of a feasibility test using a Likert scale instrument of 4 (four) assessment scores to media experts and respondents. The final product produced is a website for rooms loaning information system, by average score by media experts (Alpha Testing) of 71.6 with the "very feasible" category. The results of the feasibility test by users (Beta Testing) were 34.32 with the "very feasible" category. Therefore, it can be concluded that the website-based room loan information system is very feasible to use.

Abstract

A simulation is needed to observe and indicate how much preventive measures influence the pandemic flow, controlling and stopping it. This study succeeded in making a stochastic susceptible infected recovered deceased (SIRD) simulation using Python programming language to determine the effectiveness of prevention methods such as masks policy, social distancing, vaccination, quarantine, and lockdown. Every preventive measure is modeled based on an equivalent actual event and every essential aspect that affects the course of the pandemic. A person is represented as a circle moving freely in two-dimensional space, and disease spreads through person-to-person contact. This simulator then tested using parameters to simulate COVID-19 and found significant results between communities that implement preventive measures and those that do not. We found that within 106 days, 284 people were infected, but when five preventive methods are applied for a total of 33 days, only 31 people were infected. Adequate to simulate epidemic events and their prevention measures, this simulator can also be used as a learning tool with factors in epidemic events such as population density, mobility, infection rate, disease mortality, and every effect of each preventive measure. Users can change and influence the simulation course using interactive and straightforward software tools.

Abstract

Perkembangan teknologi dibidang industri saat ini sangat berkembang pesat, penggunaan sistem kontrol volume manual pada peralatan pengisian bahan produksi tertentu masih terus berlanjut. Tujuan dari penelitian ini adalah untuk merancang sebuah sistem kontrol pengisian bahan produksi secara otomatis. Sistem ini dibangun dengan memanfaatkan Arduino Uno Atmega328 dan Human Machine Interface, dengan komponen pendukung sistem yang terdiri dari sensor aliran air, pompa air, relai, dan catu daya. Sebuah aplikasi dimasukkan ke dalam sistem untuk pemantauan penggunaan bahan produksi. Sensor Aliran Air menghitung volume air yang dikeluarkan. Kalibrasi melibatkan memasukkan nilai konstan 0,8. Volume air dihitung dengan menjumlahkan debit air per detik melalui sensor Aliran Air. Jika batas pada setpoint sensor aliran air tercapai, pompa air akan berhenti, seperti yang ditunjukkan oleh hasil implementasi alat. Akurasi alat berkisar antara 77,76% hingga 100%, seperti yang ditunjukkan oleh hasil uji coba yang dilakukan. Persentase kesalahan tertinggi yang teramati adalah 22,24%, sedangkan yang terkecil adalah 0%, dengan deviasi rata-rata ±9,00. Kesalahan ini berasal dari perbedaan volume antara nilai yang ditetapkan oleh sensor aliran air dan jumlah material yang dikeluarkan. Data perhitungan volume disimpan dalam mikrokontroler dan ditampilkan pada layar nextion. Pengguna dapat memantau data dengan mentransfernya ke aplikasi. Kata Kunci: Auto Filling Machine, Arduino Uno, Mikrokontroler, Human Machine Interface, Sensor Aliran Air.

Abstract

Abstrak. Ketidakakuratan atau kerusakan pada meter dan CT dapat menghasilkan kesalahan pengukuran yang signifikan, yang pada gilirannya dapat berdampak pada penagihan yang tidak akurat, perencanaan jaringan yang tidak efisien, dan pelaporan yang salah. Penelitian ini menggunakan metode kualitatif. Teknik pengumpulan data yang digunakan adalah observasi dan studi pustaka. Penelitian ini dilakukan pada tiga pelanggan untuk menjaga nilai akurasi Meter dan Current Transformator (CT) pada pelanggan potensial sesuai dengan batas kelasnya. Kegiatan pengujian meter yang dilakukan oleh PT PLN (Persero) UP3 Cikupa menggunakan alat emsyst yaitu rutinitas pengecekan AMR untuk memastikan pembacaan meter oleh AMR masih berfungsi dengan baik atau error yang terdapat pada meter dan CT tersebut masih dalam batas kelas. Sehingga, pembacaan pemakaian listrik pada pelanggan masih akurat sesuai dengan jumlah energi yang dipakai.  Abstract. Inaccuracies or damage to meters and CTs can result in significant measurement errors, which in turn can impact inaccurate billing, inefficient network planning, and incorrect reporting. This research uses qualitative methods. The data collection techniques used are observation and literature study. This research was conducted on three customers to maintain the accuracy value of the Meter and Current Transformator (CT) on potential customers according to the class limit. Activities carried out by PT PLN (Persero) UP3 Cikupa using the emsyst tool, namely the AMR checking routine to ensure that the meter reading by AMR is still functioning properly or the error contained in the meter and CT is still within the class limit. Thus, the reading of electricity usage on customers is still accurate according to the amount of energy used.

Abstract

Teachers or educators find it difficult to determine student learning modalities at SMK PGRI 2 Serang City during online and offline learning. Online and offline learning must also be interesting and clear, not only images and text, but must be more interactive, because students have different learning modalities. So that in carrying out online learning the teacher must know the learning modalities of his students in order to make it easier to carry out online and offline learning. So it is necessary to create an expert system that can identify the learning modalities of students and also the accuracy of the expert system, the feasibility of efficient and effective learning modalities in online and offline learning. The stages of developing this website-based expert system design system use the waterfall method. The system development is in stages in 4 stages, namely the needs analysis stage, the design stage, the coding or implementation stage, and the system testing stage. The subjects in this study were 2 media experts, 4 teachers 1 school admin staff, and 36 students. Based on research results from testing the feasibility level of the system or product from media experts, namely 68.5 with these results it means the expert system website is in the "very feasible" category, then the results of testing the feasibility level of the expert system from users (teachers and students) are 94, 8 and 92.75 with these results in the "very feasible" category

Abstract

Workplace fire incidents can harm many parties, so a fire can cause fatalities, material losses, work losses, and other losses that can have fatal consequences. This research aims to understand the working principles of the fire detection system, determine the role of the fire alarm system in the security and safety of building occupants, and determine the causes of false alarms in the fire alarm system in the Nusantara I DPR RI Building. This research uses qualitative procedures with a descriptive approach. Information retrieval methods take the form of observation, interviews and documentation. The study showed that this fire warning system could detect and give a warning sound to all building occupants. This is due to a fire initiated by sending a signal from the detector and connected to the master panel. The role of a fire warning system in a building is to warn building occupants, workers or visitors about the presence of a fire so that they can immediately take appropriate evacuation action and extinguish the fire if possible. The factor that causes false alarms is that the detector in this fire alarm immediately detects things like cigarette smoke, dust, problems with the installation, and damaged detectors.
