Abstract

The process of drying food is done in the traditional way, by drying it in the hot sun, but the traditional drying method makes the food unhygienic. Several factors can influence the drying results of food ingredients, including temperature and drying time. Using optimal drying temperatures and times can reduce the level of damage caused by the drying process. This research aims to obtain an analysis of a food dehydrator drying machine using a hybrid-based thermostat sensor that can optimally condition the temperature and time factors in the drying process, the hyfood dehydrator machine system uses a dehumidification method, there is a heat recovery mechanism that recycles heat to open new air, thus saving 60-70% of fresh air preheating energy consumption. Hot air moving in the room dries the material. It is known that the test result data was analyzed by calculating the accuracy values, down to the relative distance values. The results of the comparison process are used as validation of the output values ??produced by the temperature measuring instrument. The measurement results of the Digital Thermostat Sensor are in accordance with the datasheet and have a high level of accuracy. So the Digital Thermostat Sensor measuring instrument can be used as a measurement tool. With an internal fan, thermostat, and time settings on this device, you only need to set the right heat according to the type of food you want to dry. The shelves in the cupboard consist of drying trays that can maximize the drying process

Abstract

The 18650 type lithium-ion battery is the type of battery most widely used in today's era, such as in electric cars, electric saws, electric drills and many more. This battery was chosen because it has stable performance, is more environmentally friendly and has a longer service life compared to other types of batteries. However, in use, lithium-ion batteries cannot stand alone, these batteries require an additional circuit, namely the BMS (battery management system), which functions to protect the battery from over charging, over discharging, short and over temperature, so that it is safe to use. Community service was carried out at SMKN 1 Tengaran, Semarang Regency, by providing material and training regarding the use of BMS on lithium-ion batteries by charging them using solar panels. This training was carried out for 3 hours with a total of 30 students, starting from delivering the material to direct practice.

Abstract

Kegiatan distribusi listrik yang dilakukan PLTU Tanjung Jati B yang berlokasi di Kabupaten Jepara menyisakan limbah hasil pembakaran batubara berupa abu fly ash dan botton ash (FABA), dengan tekstur warna abu-abu dan hitam. Limbah FABA hanya dimanfaatkan 30% untuk campuran semen dan sisanya menumpuk terbengkalai. Penelitian ini bertujuan untuk menganalisis konduktivitas pada katoda udara menggunakan material limbah batubara FABA sebagai pengganti dari karbon aktif untuk dimanfaatkan sebagai baterai ramah lingkungan. Penelitian ini merupakan penelitian terapan dengan metode eksperimen. Data penelitian diperoleh melalui eksperimen pengujian di Laboratorium Konversi Energi Listrik Universitas Semarang menggunakan FABA yang diperoleh dari PLTU Tanjung Jati B. Penelitian dimulai dengan pengambilan sampel FABA dari PLTU Tanjung Jati B, penyaringan, dan pengujian konduktifitas dengan variasi Carbon dan Graphite. Berdasarkan pengujian yang dilakukan, ditemukan bahwa baterai udara dengan memanfaatkan fly ash dan grafit dengan tegangan yang dihasilkan sebesar 2,58 V mampu menghidupkan lampu LED selama 4 hari. Untuk meningkatkan besar tegangan yang dihasilkan baterai ditambahkan larutan NaOH dengan perbandingan 1:4:2. (Fly Ash : Grafit : NaOH) Setelah ditambahkan larutan Na2Co3 tegangan meningkat menjadi 2,76 V. Ketiga bahan tersebut (Fly Ash, Grafit, NaOH) direkatkan dengan lem kertas untuk mendapatkan karakteristik kaku, teksturnya halus, cepat kering, luntur, doff, dan dapat menghantarkan listrik. Pengolahan limbah batubara FABA dapat mengatasi permasalahan PLTU Tanjung Jati B dan masyarakat untuk mengurangi penumpukan limbah batubara melalui penciptaan teknologi rekayasa berupa baterai udara.

Abstract

This community service program was conducted to enhance the technical abilities of the management team of Mushola Aljabbar, Tawangrejo, Pati regency, in operating and maintaining the audio system used for religious and social activities. The main problems identified include limited knowledge of audio installation, insufficient understanding of maintenance procedures, and difficulties in handling minor technical issues. The program employed a participatory training method that consisted of theoretical sessions, hands-on installation practice, maintenance activities, and troubleshooting simulations. Participants also took pre-test and post-test evaluations. The results indicate a significant improvement in participants’ competencies, demonstrated by an average score increase of 39.16%. Participants were able to perform basic installation, conduct routine maintenance, and independently solve common technical problems. This program had a positive impact on improving audio quality in the mushola and increasing the management’s self-reliance. Continuous training is recommended to ensure adaptability to technological developments in audio systems.
