Abstract

Home security has become an increasingly important issue as burglary incidents continue to rise, particularly when residents are away. Conventional security systems often face limitations in early detection, high implementation costs, and a lack of flexibility in integrating modern technologies. This study aims to develop an Internet of Things (IoT)-based home theft detection system that incorporates sustainable conductive plastic sensors and components as an innovative approach in smart security device development.The proposed system utilizes conductive polymer-based vibration sensors to detect physical disturbances such as forced entry attempts on doors or windows. An ESP32-CAM microcontroller serves as the main processing unit and surveillance camera, while a solenoid door lock and buzzer function as active security actuators. All components are integrated through a Wi-Fi network and connected to a Telegram application, which provides real-time notifications and remote control capabilities. When the sensor detects suspicious vibrations, the system automatically activates the camera to capture surrounding images and sends them, along with an alert message, to the user. Testing results indicate that the system operates reliably in detecting and responding to security threats, offering fast response time, low power consumption, and material efficiency. The use of sustainable conductive plastic not only enhances sensor flexibility and durability but also supports environmentally friendly principles in IoT device development. With its affordability and ease of operation, this system presents an innovative solution for improving home security through smart and sustainable technology.

Abstract

The hand is a part of the human body that serves various activities. However, if the hand is injured due to an accident, it can result in a disruption of motor function for an individual. Therefore, a Continuous Passive Motion Elbow device is needed to assist in the rehabilitation of an injured hand's elbow. While rubber and plastic materials are commonly utilized in commercial CPM devices—plastic for lightweight and durable casings, and rubber (elastomers) for flexible, skin-contacting components—this study does not yet integrate these materials in its prototype. However, the design opens possibilities for future incorporation of ergonomic plastic and elastomer components to improve user comfort, device safety, and manufacturability. The development of the Continuous Passive Motion Elbow design is necessary to improve the existing design and meet the functional needs of postoperative hand elbow therapy patients. This device is designed using an Arduino microcontroller, a DC motor as the actuator, and an optocoupler sensor as an angle reader. The Optocoupler sensor operates by detecting the gaps in the gear disc located in the device's framework. The photodiode emits infrared light, which is directed towards the phototransistor. This light is then converted into a digital signal by the microcontroller, registering as '1' when the infrared light is obstructed (indicating the absence of light reaching the phototransistor) and '0' when there is no obstruction (indicating the presence of infrared light reaching the phototransistor). These digital signals are subsequently converted into angle values through an Arduino program sketch, and the results are displayed on the LCD. In this research, the device will be tested by comparing the test results with goniometer measurements. The results of these tests will be displayed on an LCD screen. The device works effectively, exhibiting an error accuracy of 0.8%.

Abstract

Soil fertility plays a crucial role in sustaining agricultural productivity, and one effective strategy to enhance it is through the incorporation of organic matter such as humus. Although the natural process of humification requires considerable time, the resulting material greatly benefits soil structure, water retention, and nutrient availability. Modern technologies, including hydrothermal carbonization, offer the advantage of accelerating humus formation or generating comparable organic compounds within a shorter timeframe, thereby providing an efficient approach to soil enrichment. In parallel, local sheep leather tanning industries produce substantial waste, including leather scraps, sheep hair, and liquid effluents. Sheep hair is rich in keratin protein that remains underutilized, whereas fleshing waste contains proteins and fats that decompose rapidly and may cause environmental pollution if not properly managed. This study proposes a practical solution by converting such waste into organic fertilizer through hydrothermal carbonization. For this purpose, a hydrothermal reactor with a 20-liter capacity, 60 cm height, 21 cm diameter, and 10 cm wall thickness was designed to operate at 180 °C and 5 bar. Calibration of voltage, temperature, and pressure confirmed compliance with design specifications. Experimental trials using a 1:1:1 ratio of hair waste, fleshing waste, and water yielded 2,150 g of solid organic fertilizer and 2,070 g of liquid product, corresponding to an overall yield of 56.26%. In future work, the hydrothermal carbonization approach demonstrated in this study may be extended to plastic waste processing, since the similarity in carbon-rich feedstock composition allows potential adaptation of this system to convert polymeric waste into carbonaceous or biochar-like products, supporting circular-economy initiatives and sustainable material recovery through integrated organic and plastic waste treatment.

Abstract

Melaksanakan kegiatan pengabdian masyarakat bagi tenaga pengajar merupakan salah satu upaya untuk melaksanakan tugas sebagai pelaksanaan tridarma perguruan tinggi. Selain itu, dalam bidang teknologi, energi yang terbarukan mempunyai peran yang sangat penting dalam memenuhi kebutuhan energi. Salah satunya ialah energi listrik yang menjadi energi vital dalam kehidupan sehari-hari. Pada saat ini, penggunaan lampu didukung dengan tersedianya berbagai lampu hemat energi di mana terdapat sistem pada lampu tersebut akan mengkonversikan cahaya matahari menjadi tenaga listrik. Dari teknologi di atas, telah dilakukan kegiatan pengabdian di salah satu pemukiman warga di Giwangan, Yogyakarta, yaitu aplikasi lampu penerangan untuk jalan taman di Giwangan Yogyakarta berbasis solar panel. Tujuan pengabdian ini adalah memberikan bekal pengetahuan kepada masyarakat mengenai sistem lampu penerangan menggunakan tenaga surya. Pengabdian ini dilakukan dengan beberapa tahap seperti sosialisasi energi terbarukan dan teknologi penerangan jalan, konsultasi area pemasangan lampu, pemasangan lampu bertenaga surya, dan peninjauan kembali apakah telah bisa digunakan sesuai yang diharapkan. Kegiatan pengabdian aplikasi lampu solar sel telah selesai dilakukan sesuai metode yang dipaparkan

Abstract

Sabun cair merupakan kebutuhan rumah tangga yang digunakan dalam kehidupan sehari-hari seperti mencuci tangan dan mencuci peralatan dapur. Di samping itu sabun cair dapat dibuat dari minyak goreng bekas, sedangkan minyak goreng bekas jika dibuang ke lingkungan secara langsung akan mencemari lingkungan. Kegiatan pengabdian masyarakat ini bertujuan agar para akademisi dapat turut serta untuk meningkatkan perekonomian rumah tangga melalui pembuatan sabun cair dari minyak goreng bekas. Metode kegiatan ini antara lain dengan memberikan materi, diskusi, pelatihan, dan analisis kelayakan usaha oleh 4 instruktur kepada 30 peserta. Hasil kegiatan ini berupa pengetahuan dan keterampilan masyarakat dalam melakukan pembuatan sabun cair dari minyak goreng bekas serta analisis ekonominya. Hasil evaluasi menunjukkan bahwa terjadi peningkatan nilai keterserapan materi yang disampaikan dari 47,78 menjadi 94,17. Analisis aspek ekonomi menunjukkan bahwa harga jual yang ditawarkan untuk 1 botol sabun cair yaitu Rp 5000 pada saat promosi dan Rp 6000 pada keadaan normal dengan margin keuntungan sebesar 30 %. Usaha pembuatan sabun cuci ini harus menjual 128 buah botol sabun 250 ml untuk mendapat titik impas.
