Abstract

Kualitas air minum menjadi aspek penting yang harus diperhatikan untuk menjaga kesehatan masyarakat. Salah satu teknologi yang umum digunakan dalam penyaringan air adalah Reverse Osmosis (RO), yang mampu menyaring berbagai zat kontaminan. Namun, tantangan utama dalam sistem RO adalah pemantauan kualitas air secara real-time, otomatisasi dalam pengendalian pompa air, serta penggantian filter yang sering kali tidak terjadwal dengan baik. Oleh karena itu, penelitian ini mengembangkan sistem pemantauan dan kontrol kualitas air RO berbasis Internet of Things (IoT) dengan pendekatan logika fuzzy metode Sugeno untuk meningkatkan efisiensi dan efektivitas pengelolaan air RO. Hasil penelitian menunjukkan bahwa sistem yang dikembangkan mampu membaca parameter air dengan akurasi tinggi setelah dilakukan kalibrasi sensor, dengan akurasi sensor pH mencapai 97%, sensor TDS 97,21%, dan sensor kekeruhan 95%. Implementasi metode fuzzy Sugeno berhasil meningkatkan akurasi penentuan kualitas air hingga 97%, dibandingkan dengan metode pemantauan manual yang lebih subjektif. Selain itu, sistem IoT berbasis Blynk memungkinkan pengguna untuk memantau kualitas air secara jarak jauh dan real-time, serta memberikan notifikasi otomatis jika kualitas air turun di bawah ambang batas yang telah ditentukan.. Penerapan sistem ini sangat sesuai untuk lingkungan seperti Pondok Pesantren Durrotu Aswaja, yang membutuhkan akses terhadap air minum berkualitas secara berkelanjutan.

Abstract

Kelompok Tani Ngambarsari terletak di Mangunsari Kota Semarang Jawa Tengah mengalami permasalahan pertanian yaitu serangan hama burung pipit dan ketidaksesuaian tingkat keasaman tanah. Solusi permasalahan ini berupa alat pengusir hama burung dengan sensor pH berbasis Internet of Things (IoT). Alat ini menggunakan energi surya dan diakses melalui aplikasi smartphone. Metode pelaksanaan mencakup pembentukan tim, survei, desain perancangan alat, pembuatan alat dan aplikasi, uji coba, pembuatan buku pedoman, sosialisasi, implementasi, dan evaluasi. Hasil pengujian menunjukkan peningkatan signifikan dalam produktivitas pertanian. Alat ini dapat meningkatkan hasil panen gabah menjadi beras dari 55% menjadi 60% dalam 90 m2, dengan keuntungan 177,12 kg beras per 90m2 dibandingkan dengan kondisi sebelumnya. Implementasi sensor pH tanah pada alat ini membantu petani dalam mengelola pupuk dengan mengontrol tingkat keasaman tanah secara real-time.

Abstract

In limited face-to-face learning, teachers and students must implement health protocols to prevent the spread of the Covid-19 virus. However, implementing health protocols in schools as a new habit in the midst of a pandemic is certainly not easy. There are many reports related to the number of violations of health protocols in schools during face-to-face learning. Therefore, by innovating and utilizing existing technology in the 4.0 era can help us to detect social boundaries. The purpose of this service activity is so that teachers and students can learn YOLO-based computer vision technology at SMKN 4 Malang as a means of preventing the spread of Covid-19. In addition, teachers and students can also learn to make simple applications based on YOLO. This activity begins with the socialization of YOLO-based computer vision technology as a crowd detection tool to the school. Then the design and manufacture of crowd detection tools by the service team, training in making crowd detection applications, and ending with a discussion between the trainees and the service team. The results of the service show that this activity has succeeded in developing a crowd detection tool that can help calculate the number and distance of people who do not apply health protocols at SMKN 4 Malang. This tool makes it easier for schools to monitor the activities of school residents in implementing health protocols. This service activity is very useful and in demand by teachers and students. This is evidenced by the enthusiasm of the participants in participating in the training of YOLO-based crowd detection tools.

Abstract

Access to technology which continues to develop very rapidly means that the government, especially at the village government level, must start developing a service system that is oriented towards the use of digital technology. The purpose of this community service is technology-based village service education that can make it easier for the community to access village documents. The community service method applied is socialization and training targeting the village community and village officials. The results of the community service show that the community and village officials can use carrd.co as a medium for providing information regarding the requirements for making various civil population administration documents, such as civil population letters such as birth certificates, death certificates, KK (Family Cards), and so on. In addition, by using carrd.co which is integrated with the Randugunting Village Instagram, the community can also easily access the village government structure, village activities, village administration services, and others. With the comprehensive and sustainable use of digital technology, it is hoped that it can bring the village towards a digital and modern direction.

Abstract

Fire detection systems commonly rely on a single variable, such as smoke or flame, to detect fires. However, using a single sensor or threshold-based method for early detection is prone to false alarms. To address this issue, this study proposes an early fire detection system using an artificial neural network based on the Radial Basis Function Network (RBFN) architecture. The aim of this research is to minimize false alarms by implementing an early fire detection system that not only detects flames but also hazardous gases, temperature, and humidity as potential sources of fire. A multisensor system comprising an IR flame sensor, gas sensors MQ-9, MQ-2, and MQ-4, as well as a DHT-11 temperature and humidity sensor, was integrated and processed using an RBFN-based ANN on a Raspberry Pi 3. The ANN processes a series of datasets trained to generate a model that determines fire conditions. Testing results showed that the proposed method did not produce any false alarms, with a response time of 2.1 seconds from the ignition of a fire source to the issuance of a warning.

Abstract

The socialization of making Pupuk Organic Cair (POC) in Randugunting Village is an effort to deal with the abundance of household organic waste. This outreach aims to utilize household organic waste such as wilted vegetables. This household organic waste rots very quickly and carries many diseases if left untreated. Therefore, this waste is processed into fertilizer which is useful for the residents around Randugunting Village. The socialization methods used are training and direct practice. The community service’s results revealed that Pupuk Organik Cair produced had sufficient nutritional content, including nitrogen, phosphorus and potassium, which are essential for plant growth. After the socialization is complete, the result are used to water the village's TOGA. Thus, the manufacture of Pupuk Organik Cair in Randugunting Village provides direct benefits for residents through increasing TOGA yields, while supporting more environmentally friendly and sustainable agricultural practices.
