Abstract

Agroforestry is a cropping pattern that is commonly applied to private forest management in Indonesia. Agroforestry based private forest is a land-based silviculture that incorporates forestry plants with agricultural crops, plantation crops, and multi-purpose plants. One of the felling techniques used in agroforestry based private forests is the sandat-felling technique (SFT), which is a rope-assist felling technique. The felling technique was used to protect the remaining stand of the agroforestry based private forest. This technique is an innovation in the harvesting of agroforestry based private forests in Indonesia. The time consumption and productivity of this technique are not yet known. This study aims to assess the working time and productivity of SFT in agroforestry based private forests in Probolinggo, East Java, Indonesia. The observed tree-felling technique included rope installation and tree-felling operations. The performance of the SFT was evaluated by analyzing its working time and productivity. The results of the study showed that the total working time of the SFT was 8.65 minutes tree-1, which consisted of 33.34% for rope installation and 66.66% for felling operation. The productivity of the SFT was 2.02 m3 hour-1.

Abstract

Perkembangan teknologi saat ini berkembaang di berbagai bidang dan membawa berbagai dampak dalam kehidupan. Dalam bidang pendidikan salah satunya, dengan memnafaatkan teknologi dapat membantu perkembangan pengetahuan wawasan siswa dalam kegiatan belajar mengajar. Sistem Pendeteksi Kebakaran atau SISPEK berbasis Internet of Things (IoT) merupakan sistem yang dirancang untuk mendeteksi kebakaran maupun asap yang diimplementasikan dengan media edukasi sebagai pembelajaran untuk siswa agar mengetahui dan mengenai teknologi IoT yang dapat digunakan dan dimanfaatkan dalam kegiatan sehari-hari. Selain itu, tujuan dalam penelitian ini adalah sebagai pendeteksi kebakaran yang mampu membantu mengidentifikasi apabila terjadi kebakaran didalam ruangan maupun di kelas, sehingga dengan adanya SISPEK dapat membantu pengevakuasian murid dan meminimalisir terjadinya kerugian baik untuk anak sekolah maupun pihak sekolah itu sendiri. Serta hal ini dapat mengurangi kerusakan properti, perlengkapan, dan aset berharga, serta menghindari korban luka bagi anak-anak sekolah. Penelitian ini, menggunakan metode pendekatan User-Centered Design (UCD) dimana prototipe alarm kebakaran yang dirancang merupakan sistem interaktif terhadap pengguna berbasis IoT sebagai bentuk media edukasi keselamatan didalam ruangan atau di kelas. Berdasarkan kuisioner didapatkan hasil pre-test menunjukkan kesadaran tinggi bagi seluruh siswa kelas 5B di SD Lab School UPI Purwakarta, terkait akan pentingnya keselamatan dari kebakaran di sekolah dasar. Antusiasme siswa menjadi faktor kunci keberhasilan simulasi, dengan tingkat kesadaran terhadap kebakaran yang tinggi. Hasil post-test menunjukkan efektivitas kegiatan, dengan 96,3% siswa menyatakan materi bermanfaat. Tingkat pemahaman siswa tentang IoT meningkat, dan 27 siswa menganggap alat pendeteksi kebakaran berbasis IoT (SISPEK) diperlukan oleh sekolah. Oleh karena itu, kegiatan ini sukses meningkatkan kesadaran dan pengetahuan siswa kelas 5B terkait evakuasi dini dan penerapan IoT dalam kehidupan sehari-hari yang dapat memberikan nyamanan dan kemudahan.

Abstract

Cataract, a condition characterized by clouding of the eye's lens, leads to decreased vision and potentially blindness. In Indonesia, it is the predominant cause of blindness, accounting for 81.2% of cases. Given the rising life expectancy, the incidence of degenerative diseases like cataracts is expected to increase. This research aims to develop a cataract detection system capable of classifying eye images as either indicative of cataracts or normal. Utilizing Convolutional Neural Networks (CNN) and RGB-based image processing—including edge detection techniques such as Canny and Prewitt—the system identifies eye contours. This facilitates image segmentation to ascertain the eye's condition. Therefore, image collection and processing models play a crucial role in this study. The research findings indicate that the system functions effectively, with a 98% success rate in accurately processing normal eye images through the CNN model without detecting cataracts. When tested using grayscale imaging, cataract-afflicted eyes—characterized by red spots in the images—were also successfully identified by the CNN model. These test results demonstrate that the designed cataract detection system can accurately classify images into normal or cataract-afflicted eyes with high precision. This system shows promise for use in early cataract detection, potentially helping to reduce the prevalence of cataract-related blindness in Indonesia.

Abstract

Currently, people are often unaware of the existence of hotspots or gas leaks in the house which can trigger large fires in the house. Therefore, this research focuses on designing a fire monitoring and extinguishing system that can detect early IoT-based fires using the SIM800L GSM module on unmanned vehicles to detect fires and immediately extinguish them, accompanied by sending emergency messages via the SMS application on smartphones. As a warning, a fire has been detected in the house so that people can be more alert. In addition, this system is designed so that the vehicle can be controlled remotely using the HC-06 Bluetooth module and Bluetooth RC Car. This early fire detection process will be tested 30 times, each sample will be tested for the time speed obtained in detecting and extinguishing a fire. Thus, this system has the potential to prevent fires which can cause major losses.

Abstract

Directional felling is a technique that directs fallen trees in a predetermined direction to minimize damage to residual stands and understory plants and facilitate subsequent stages of timber handling. One of the felling techniques used in private forest harvesting was the rope-assisted directional felling technique. The study aimed to analyze and evaluate the effectiveness of the rope-assisted directional felling technique in private forests. The study was conducted in a private forest managed with an agroforestry system in Probolinggo, East Java. The number of sampled trees was 31 trees. The sampled trees were felled to the predetermined directions: to a stretched rope between two spar trees or the safe area. Felling errors, hang-ups, and the presence of barber chairs were used to assess the effectiveness of the rope-assisted felling technique. The average diameter of the felled trees was 23.4 cm and 20.8 m in height. The ropes-assist directional felling technique produced a hang-up tree of 19.35% of the total felled trees. Directional felling using ropes made fallen trees from close to the opposite direction of the natural felling direction. The ropes-assisted felling technique made all felled trees fall in the predetermined direction without producing barber chairs, but still causing hang-ups.
