Abstract

Different types of attendance systems are used in various settings such as schools and companies, namely web-based systems that can be used as a substitute for absenteeism. Another attendance system being developed is a QR Code based attendance system which requires user verification using RFID fingerprint or voice command. It is necessary to develop an attendance system that uses RFID sensors at universities as a technological adaptation.Currently, lecture attendance at the Fakfak State Polytechnic College, especially in the Informatics Management Department, still uses a manual attendance system, namely taking attendance of students using an attendance book every class hour. Running absenteeism creates a problem, namely that it is impractical. The impracticality of this system can be that it takes a lot of time to register students one by one, thereby cutting into course hours. Not to mention the phenomenon of leaving absences which usually takes advantage of lecturers' negligence to sign the absences of friends who are unable to come. You can also directly sign attendance from the first meeting to the last meeting. So the author conducted research on making student attendance tools that use RFID, and can monitor student attendance data by lecturers via a website. Based on these problems, an attendance system based on RFID (Radio Frequency Identification) using NodeMCU is expected to be able to solve these problems.

Abstract

Generator merupakan alat yang digunakan untuk mengubah energi gerak mekanik menjadi energi listrik dengan frekuensi putaran rotor sama dengan frekuensi tegangan yang dibangkitkan. Generator menggunakan prinsip elektromagnetik dalam pengoperasian energinya. Permasalahan yang sering muncul pada generator adalah penggunaan beban yang berlebihan sehingga menimbulkan perlambatan pada putaran rotor. Ketika kebutuhan beban meningkat dan tidak dapat dipenuhi oleh generator maka perlu dilakukan pelepasan beban pada system. Hal ini dimaksudkan untuk menstabilkan frekuensi serta keseimbangan antara daya generator dan beban. Pada penelitian ini telah diketahui bahwa pembebanan sangat berpengaruh terhadap frekuensi generator. Berdasarkan hasil pengukuran beban diketahui bahwa beban sebesar 350 kW, 400 kW dan 440 kW menyebabkan terjadinya penurunan frekuensi menjadi 49,8 Hz, 49,2 Hz dan 49 Hz.

Abstract

he world's energy industries contribute 87% to the increase in global greenhouse gases. To reduce global greenhouse gas emissions, hydrogen as clean energy is an alternative energy source with a gravimetric energy density of 120 MJ/kg and a volumetric density of 0.0824 kg/m3. The main challenge of hydrogen as an energy carrier is its low volumetric density, thus requiring hydrogen storage technology at higher volumetric densities. Hydrogen storage systems are crucial to the hydrogen supply chain process, especially in terms of its economics. The hydrogen storage system consists of hydrogenation, transportation, and dehydrogenation processes. This paper uses the techno-economic analysis of five types of hydrogen storage technologies: compressed hydrogen, liquid Hydrogen, liquid organic hydrogen carrier, metal hydride, and ammonia. Hysys was introduced to help process design, process modeling, and equipment sizing of each technology. System costs ($/kg) are determined based on projected Capital Expenditure (CapEx) and Operational expenditure (OpEx) of each hydrogenation and dehydrogenation process, as well as shipping transportation cost at 2000 km. The results show that liquid organic hydrogen carrier had the lowest system cost of $2.84/kg, followed by metal hydride at $2.95/kg, compressed hydrogen at $3.33/kg, ammonia at $7.21/kg, and liquid hydrogen at $11.51/kg. However, the storage efficiency of liquid organic hydrogen carriers is only 8.73%, compared to compressed hydrogen at 99%. The results show that the cost of hydrogen storage systems needs to be significantly reduced for long-term and large-scale applications.

Abstract

This study aims to improve extracurricular learning outcomes in class X of Guguak Randah integrated MAS by applying a creative problem-solving learning model. Through interviews with the integrated teacher, Mrs. Syarifah,, it was revealed that the learning process still relies on the lecture method and teacher-centered approach which causes a lack of student interest in learning. To overcome this problem, the researcher is interested in applying a creative problem-solving learning model so that students are more involved and their learning outcomes improve. The research used a quasi-experimental method with a post-test only control group design. In this context, the use of the Creative Problem Solving model on students of class X IPA integrated MAS Guguak Randah showed a significant effect on learning outcomes. The t-test results confirmed a significant difference between the experimental group that applied the creative learning model and the control group. Thus, the application of this model can stimulate student creativity, improve learning interest, and make the learning process more interesting and interactive.

Abstract

Methanol plant from glycerol is a good prospect in Indonesia. Until 2021, methanol is only supplied by one methanol producer located in East Kalimantan, namely PT. Kalimantan Timur with a production capacity of 660,000 tons/year. Therefore, the methanol plant from glycerol has a very important meaning for the acquisition of foreign exchange as well as employment. This article presents an economic evaluation of a methanol plant from glycerol with a capacity of 40,000 tons/year. Profitability analysis calculation is done by two methods, the method that do not consider the time value of money and the method that consider the time value of money. The results of the method that do not consider the time value of money obtained ROI value (before tax) 34.62%, ROI value (after tax) 24.24%, and the value of PBP 2.98 years. Using the method that consider the time value of money, the NPW value was Rp. 1,458 billion and the DCFRR / IRR was 39.25%. The sensitivity analysis also deserves to see the effect of the factor that influence the economic viability, and provide more information for the optimization of Methanol production.

Abstract

Perubahan iklim telah secara signifikan mempengaruhi arsitektur dan lingkungan, termasuk di Indonesia, negara beriklim tropis yang rawan terhadap perubahan iklim. Pentingnya pengelolaan sumber daya alam dengan bijaksana menjadi semakin terasa. Beberapa bangunan telah berhasil menyesuaikan diri dengan tantangan ini, sementara yang lain tertinggal dalam adaptasi. Praktik arsitektur ekologis menjadi krusial dalam mengurangi dampak negatif terhadap lingkungan. Penelitian ini menyoroti pentingnya menerapkan prinsip-prinsip arsitektur ekologis, seperti kenyamanan termal, pemilihan material, respons terhadap kondisi tapak bangunan, dan lain-lain. Fokusnya adalah Kompleks Istora Senayan Jakarta. Dengan metode kualitatif deskriptif dan merujuk pada teori Heinz Frick tentang desain arsitektur ekologis, penelitian ini menunjukkan keberhasilan dalam mengintegrasikan aspek-aspek ekologis dalam desain bangunan. Hasilnya menegaskan bahwa kolaborasi antara praktisi arsitektur dan ilmu lingkungan penting untuk merancang bangunan ramah lingkungan di masa depan. Penelitian ini memberikan pandangan tentang peran arsitektur dalam menghadapi tantangan perubahan iklim.
