Abstract

In Indonesia, the theft rate is still quite high. According to Bappeda data, cases of theft still tend to be high. In 2019, there were 362,000 cases of theft. CCTV use is still ineffective because at the time of the theft of goods, we only know the goods taken and the perpetrators. In order to catch the perpetrators and return the goods, it is necessary to process them first and find the location of the perpetrators themselves. Therefore, we propose an idea entitled "Activation Control System in Motorized Vehicles Using GPS". Where this tool will detect the position of a vehicle so that this vehicle remains in a restricted area. When this vehicle leaves the restricted area, the GPS system will send a signal explaining that the vehicle is leaving the area. So, if there is a theft, when the vehicle has moved away from about 50 meters from the area that has been locked, a notification will appear which will be displayed on the web application. The research stages that we will work on are first identifying the equipment and systems that will be used and conducting a study of the technology literature that will be developed, then identifying the theoretical and empirical system design and knowing the basic elements. Then master and understand the characterization of components and analyze the main functions so that they can work properly. Then do modelling and simulation and ensure that the components to be developed can work properly. And the final stage is to ensure that the system equipment is valid and reliable. Based on the results of the study, it shows that the system is active when the actual position away from the locked position/area as far as 100 meters has successfully functioned. Where the information changes to "Out of reach" from the previous "Within Reach" and there are notifications in the form of sound and vibration to increase security from theft.

Abstract

Pengabdian ini bertujuan untuk meningkatkan efektivitas dan efisiensi pengelolaan dokumen mutu melalui penerapan Document Control System (DCS) berbasis digital di UPTD Puskesmas Garuda. Permasalahan utama yang dihadapi mitra meliputi pengelolaan dokumen yang masih dilakukan secara manual, lamanya proses pencarian dokumen, risiko kehilangan arsip, serta lemahnya pengendalian revisi dan distribusi dokumen antar unit kerja. Metode pengabdian yang digunakan adalah pendekatan partisipatif berbasis pendampingan yang dilaksanakan melalui beberapa tahapan, yaitu analisis kebutuhan, perancangan sistem, pengembangan aplikasi, implementasi sistem, pelatihan dan pendampingan pengguna, serta evaluasi kegiatan. Sistem dikembangkan berbasis web menggunakan framework Laravel 11 dengan penerapan Role-Based Access Control (RBAC) dan fitur audit trail untuk meningkatkan keamanan serta keterlacakan dokumen. Hasil pengabdian menunjukkan bahwa implementasi DCS mampu mentransformasi pengelolaan dokumen mutu dari sistem manual menjadi digital, terstruktur, dan terpusat. Waktu pencarian dokumen yang sebelumnya membutuhkan sekitar 15–30 menit berhasil dipangkas menjadi kurang dari 2 menit melalui fitur pencarian digital. Selain itu, penerapan RBAC dan audit trail terbukti mampu meningkatkan keamanan data, mencegah modifikasi dokumen ilegal, serta memperjelas riwayat revisi dokumen. Pelaksanaan pelatihan menggunakan metode Key User Training juga berhasil meningkatkan kemampuan staf dalam mengoperasikan sistem secara mandiri. Simpulan pengabdian ini menunjukkan bahwa penerapan Document Control System (DCS) efektif dalam meningkatkan efisiensi, keamanan, dan akuntabilitas pengelolaan dokumen mutu di UPTD Puskesmas Garuda serta mendukung transformasi budaya kerja menuju sistem administrasi berbasis digital (paperless office) untuk menunjang kesiapan akreditasi fasilitas kesehatan.

Abstract

Background Conventional room cooling systems generally operate at fixed fan speeds without considering variations in room temperature and occupant density, leading to reduced thermal comfort and inefficient energy consumption Purpose This study aims to design and implement an automatic room cooling system that adjusts fan speed based on room temperature and visitor density using Mamdani fuzzy logic control. Methodology The system integrates a DHT22 sensor to measure room temperature and an ultrasonic sensor to estimate visitor density. Mamdani fuzzy logic was employed to process linguistic variables for temperature ("cold," "normal," and "hot") and visitor density ("sparse," "crowded," and "very crowded") to determine the appropriate fan speed. Findings Experimental results demonstrate that the system successfully adjusts fan speed according to environmental conditions. At 17°C with 6 visitors (sparse), the fan operates at low speed (PWM = 39.6), while at 34°C with 37 visitors (very crowded), it reaches high speed (PWM = 211). Under moderate conditions (22°C with 25 visitors), the fan operates at medium speed (PWM = 125), indicating effective adaptive control. Implications The proposed system improves occupant comfort while promoting energy efficiency through adaptive fan speed control. It can be applied in meeting rooms, seminar halls, conference rooms, and other indoor environments with dynamic occupancy levels. Originality This study presents an adaptive room cooling system that integrates room temperature and visitor density using Mamdani fuzzy logic, providing a practical and energy-efficient solution for intelligent indoor environmental control.
