Abstract

Internet of Think (IoT) is emerging as a big issue on the internet, it is expected that billions of objects will be equipped with various types of sensors connected to the internet through networks as well as technology support such as embedded sensors and actualization. This study aims to design and analyze the application of a prototype door locking system via the internet using Arduino Uno based on Android. This research uses the SDLC method in designing and developing a prototype door lock system over the internet using Arduino Uno based on Android. There are 3 stages of the SDLC method used in this research, namely Requirements Analysis, System Design, and System Implementation. The input from this system is in the form of on and off commands from smartphones that are sent to thingspeak as a server service and will be continued to Arduino devices that have been connected to a solenoid doorlock. If the door is opened, the magnetic sensor switch will send the information back to Thingspeak and continue to the smartphone as feedback. The results of the tests that have been carried out are that the average time required for lock = 4.36 seconds and unlock = 5.30 seconds, while the average sensor test time required to send sensor data with conditions Open = 12.33 seconds and Closed = 12.43 seconds. The delay time depends on the condition of the network connected to the system.

Abstract

This research focuses on the development and testing of a microprocessor-based Overcurrent Relay (OCR) with the implementation of fuzzy logic control for adaptive setting of TMS values. OCR is a crucial component in the electricity protection system which aims to detect and respond to disturbances due to excessive current, preventing damage to electrical equipment. The aim of this research is to test the feasibility and performance of microprocessor-based OCR with fuzzy logic control in setting TMS values, and compare it with the international standard IEC 60255. The method used in this research is the implementation of the Sugeno type fuzzy logic algorithm on the Atmega 328P microcontroller. This algorithm is used to control the TMS value based on the rotating frequency of the detected overcurrent. The results of this research are a characterization of the OCR response to variations in streaming current and different PS settings. The lowest TOp deviation was observed at higher PS settings, with the best performance in the IDMT OCR type. The use of fuzzy logic control is able to increase the OCR response to overcurrent disturbances, although under normal conditions it sometimes results in a longer TOp. The conclusion of this research is that microprocessor-based OCR with fuzzy logic control can provide protection performance that is adaptive and responsive to dynamic operational environmental conditions. This implementation has the potential to increase the efficiency and leakage of the electricity protection system

Abstract

Red Onions are agricultural commodities that are a source of income for farmers and can make a major contribution to Indonesia's economic development. The characteristic of the onion plant is that it requires a lot of sunlight. The sunlight needed for photosynthesis is 70% with an ambient temperature range of 25oC-32oC and soil moisture in the range of 50%-70%. Although red onions require a lot of water, these plants are sensitive to high-intensity rainfall. The critical period of the red onion plants is in the tuber formation phase so it is necessary to control it to get maximum production results. The method of making the smart farming system uses the Research and Development (R&D) method while sending data online to the web uses the Internet of Things (IoT) method. The result of this research is that a monitoring and control system for temperature and humidity has been successfully built on red onion plants. The system built is capable of measuring temperature with an accuracy rate of 95.33% and environmental humidity in plants reaching 92.07% while the accuracy of testing the entire system reaches 93.33%. The smart farming system has been able to automatically irrigate and apply fertilizer. Control of irrigation and application of fertilizers by the system has implications for better shallot growth and creates modern agriculture.

Abstract

The apriori algorithm uses minimum support and minimum confidence to determine appropriate itemset rules for decision making. The problem faced in this research is how to improve the performance of the a priori algorithm in the process of searching for itemset frequencies using data partition techniques, and be able to produce optimal and consistent rules. To overcome this problem, the author implemented the a priori method and partition system to improve the performance of the a priori algorithm for the itemset frequency search process by taking public data in the form of supermarket transaction data. In this research, the performance of the a priori algorithm was tested with and without a partition system. The data used in this research consists of 350 transaction data from 1784 records with a 4-itemset pattern, minimum support value of 20% and minimum confidence of 0.5 with the best standard rules for determining minimum confidence of 0.8. Based on this research carried out, the research results obtained are that for comparison of time and memory usage the apriori algorithm with a partition system is much faster than the apriori algorithm without a partition system, while memory usage is relatively less for the apriori algorithm with the system than the apriori algorithm without a partition system.

Abstract

Nowadays, the environmental issue is one of the biggest problems worldwide. It is because the climate change deteriorates from time to time; the earth becomes warmer, and pollution polluted the environment. Humans have a pivotal role in changing the earth because they damage the ecosystem by using numerous plastics, throw many of rubbish, and cutting plenty of trees. As a result, climate change and global warming become worse. Consequently, all stakeholders need to take the responsibility to protect the earth. Some groups blame the government; however; environmental issues are the government’s responsibility and all society’s matters, including academicians. This community service activity was conducted in one of the remote areas in Bunbeleng village, East Sekotong district, East Lombok. The Project was held by Relawan Saling Jaga Indonesia (Relasi) funded by Direct Aid Program (DAP) Australian Consulate-General, Bali Indonesia coordinated by Isyatul Mardiah. This project was conducted based on Project-based Learning (PBL). There are five stages in implementing this project: planning the project, monitoring the project, presenting the project, and evaluating the project. The environment topics were elaborated in this community through the PBL. After the program, the students have more knowledge in reducing, recycling, and reusing plastics and green programs with planting trees. The students were very enthusiastic and motivated. The collection of the project was exhibited isn the classroom.

Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk memperkuat nilai-nilai sadar wisata di kawasan Pantai Kerandangan, Senggigi, sebagai upaya mendukung pengembangan destinasi wisata berbasis kearifan lokal dan komunitas. Pantai Kerandangan memiliki potensi alam dan budaya yang tinggi, namun belum sepenuhnya dikelola dengan pendekatan yang melibatkan masyarakat secara aktif dan berkelanjutan. Latar belakang kegiatan ini didasarkan pada temuan awal bahwa sebagian besar masyarakat masih belum memahami secara utuh prinsip-prinsip dasar sadar wisata, seperti keamanan, ketertiban, kebersihan, kenyamanan, dan keramahan, yang sejatinya merupakan fondasi penting dalam membangun pengalaman wisata yang berkualitas. Kegiatan dilaksanakan pada 9 Juni 2025 dengan menggunakan pendekatan edukatif-partisipatif, yang menekankan pada keterlibatan aktif masyarakat dalam setiap proses pembelajaran. Empat tahapan utama dilalui, yakni perencanaan, persiapan kegiatan, pelaksanaan, dan evaluasi. Selama kegiatan, peserta mendapatkan materi interaktif, terlibat dalam Focus Group Discussion (FGD) untuk menggali potensi lokal, serta mengikuti simulasi pelayanan wisata berbasis budaya. Evaluasi dilakukan melalui pre-test dan post-test, yang menunjukkan peningkatan signifikan dalam pemahaman peserta, dari rata-rata skor 52,4 menjadi 85,7.Refleksi kelompok di akhir kegiatan memperlihatkan bahwa pendekatan ini efektif tidak hanya dalam meningkatkan pengetahuan, tetapi juga dalam menumbuhkan semangat kolaboratif serta komitmen untuk menjaga dan mempromosikan identitas budaya sebagai daya tarik wisata. Kegiatan ini diharapkan menjadi model yang dapat direplikasi di destinasi lain yang memiliki karakteristik serupa.
