Abstract

Electrical energy needs will continue to increase in line with the needs of the community, both on an industrial scale and the household in general. On the other hand the supply of fuel oil and coal as a driving force for power station centers is increasingly depleting. Because of that, a lot of research is needed to obtain renewable energy, as well as being environmentally friendly. One of the abundant energy sources in Indonesia is water resources. Utilization of water resources can be done by building a Micro Hydro Power Plant (MHPP). Based on the results of the study through literature studies, from as many as 13 journals (in 2009-2019) it can be seen that in Indonesia there are still many regions that have not yet received electricity supply from PT. PLN, with the following reasons: (1) the availability of PT. PLN is not enough to meet the needs of the community; and (2) many areas are located far from the PLN electricity network; and (3) many regions whose infrastructure does not support the expansion of the PLN electricity network. This condition is hampering the speed of economic development in the regions concerned. The study found that: (1) there were 13 points of water resources that could potentially be built by MHPP with electrical power varying depending on the amount of water resources concerned; and (2) from the results of the study, there are a number of studies that have been implemented and some of them are still in preparation for the construction of the MHPP.

Abstract

Sistem smart home saat ini telah banyak diterapkan dalam kehidupan sehari-hari. Smart home mampu memberikan keamanan dan kenyamanan pada penghuni rumah. Sistem ini bekerja dengan mengontrol beberapa peralatan rumah tangga. Pada umumnya sebagian besar sistem kendali peralatan listrik rumahan masih bersifat manual yaitu dengan menghubungkan peralatan listrik pada stop kontak atau menekan saklar secara langsung. Penerapan sistem kendali manual seringkali membuat pengguna lupa mematikan saklar atau peralatan elektronik lainya saat sedang keluar rumah. Oleh karenanya, pengguna diharuskan untuk mematikan secara manual dengan kembali ke rumah atau terkadang dibiarkan menyala oleh pemilik rumah. Penerapan sistem kendali yang dapat dioperasikan dari jarak jauh diperlukan untuk mengatasi hal ini. Sistem ini mampu membuat pengoperasian dan pemantauan peralatan listrik menjadi lebih efisien. Pada penelitian ini, prototipe sistem smart home dibuat dengan memanfaatkan fitur chat yang tersedia pada Telegram yang dipakai untuk mengontrol relay modul. Sistem bot pada Telegram digunakan sebagai pengirim dan penerima pesan untuk mengontrol relay modul yang terhubung pada peralatan kelistrikan. Metode yang digunakan dalam penelitian ini adalah Research and Development. Sistem dikembangkan menggunakan Modul NodeMCU ESP32 perangkat lunak Micropython. Berdasarkan hasil pengujian yang dilakukan, menunjukkan bahwa hasil uji kelayakan rata-rata keseluruhan adalah 84% yang meliputi aspek desain alat, aspek kinerja alat, aspek kemudahan pengoperasian dan implementasi. Penilaian hasil uji kelayakan diberikan oleh narasumber ahli dibidangnya sehingga menunjukkan bahwa prototipe ini sudah cukup baik dan layak untuk diterapkan pada sebuah rumah. The smart home system is now widely applied in everyday life. Smart home can provide security and comfort to the occupants of the house. This system works by controlling several household appliances. In general, most control systems for home electrical equipment are still manual, namely by connecting electrical equipment to a wall socket or pressing the switch directly. The application of a manual control system often makes users forget to turn off switches or other electronic equipment when leaving the house. Therefore, the user must turn it off manually by returning home, or sometimes it is left on by the homeowner. The application of a control system that can be operated remotely is required to overcome this. This system can make the operation and monitoring of electrical equipment more efficient. In this study, a smart home system prototype was created by utilizing the chat feature available on Telegram, which controls the relay module. The bot system on Telegram is used as a message sender and receiver to control relay modules connected to electrical equipment. The method used in this research is Research and Development. The system was developed using the NodeMCU ESP32 Module and Micropython software. Based on the tests conducted, the overall average due diligence result is 84% , including aspects of tool design, tool performance, and ease of operation and implementation. Expert sources assessed the feasibility test results in their fields to show that this prototype was good enough and feasible to be applied to a house.

Abstract

Objective: To evaluate baseline student satisfaction, compare service quality between two “Accredited Excellent” vocational engineering programs-S1 Building Engineering Education (PTB) and S1 Mechanical Engineering Education (PTM)-and diagnose operational bottlenecks to align empirical findings with institutional quality assurance and global educational standards. Method: A quantitative comparative-descriptive survey design was conducted with a stratified random sample of N = 422 undergraduate students (PTB N1 = 215 and PTM N2 = 207). Data were collected using a 23-indicator SERVQUAL instrument on a 4-point Likert scale and analyzed using descriptive statistics (Mean, Standard Deviation, Respondent Achievement Degree/TCR), independent-samples t-tests (α = 0.05), and Cohen’s d effect size estimations. Results: Although overall satisfaction reached a “Satisfied” baseline (TCR = 75.47%), inferential testing revealed a statistically significant disparity (p = 0.0429) favoring PTB over PTM. Granular item analysis isolated critical operational bottlenecks in laboratory equipment adequacy (P18), general campus facility accessibility (P23), and administrative responsiveness in facility loan procedures (P16). Novelty: The research shows that top-tier accreditation does not guarantee uniform program-level service delivery, offering a pioneering framework that directly integrates granular SERVQUAL diagnostics into the institutional Internal Quality Assurance System (SPMI-PPEPP cycle) and United Nations Sustainable Development Goal 4 (Targets 4. a and 4.4).
