Abstract

The creation, transmission, distribution, and consumption of electrical energy are the first steps in the provision of electrical energy. The efforts that are made to conserve energy need to be continuously improved to supply electricity that is affordable. In order to conserve energy, it is necessary to have the backing of technology, laws, and legislation, in addition to applying behavioral discipline to those who utilize energy. To put it simply, a smart energy meter is one of the fundamental components of conservation technology. At the moment, the bulk of PLN's 67.6 million clients make use of traditional energy meters that are powered by electromechanical technology. The measuring device has not been incorporated with the technology that is associated with the internet of things (IoT). On the other hand, electronic items like televisions, washing machines, and air conditioners have started to adopt the Internet of Things and become smart devices. The integration of smart gadgets and smart meters enables the creation of an energy management system that can be used to the consumption and distribution of electricity in residential or commercial facilities. At Tiara Sella Hospital, which has a high monthly energy consumption, this community service project was carried out in order to measure the optimization of energy use and to determine opportunities for improvement. It is believed that the installation of this energy meter would result in improved and more reliable methods of measuring and estimating the amount of energy that is utilized within the hospital setting, which will allow for more sustainable optimization efforts.

Abstract

The rotary system sweet potato washing machine is used to clean sweet potatoes that are dirty and contain lots of soil and other impurities such as microorganisms. The rotary system which rotates and rolls is used for perfect movement, so that the dirt covering the sweet potato is removed completely. The aim of this activity is to test and determine the production capacity of the rotary system of sweet potato washing machines used by sweet potato collecting farmers. The testing was carried out by putting a number of sweet potatoes into the washing tub, along with running water as a cleaning fluid. The drum is rotated with a rotation speed of 1430 rpm which is connected to a gear ratio of 1:30, so the rotation speed is smaller. The stirring arm is moved simultaneously with the movement of the drum. The rotating stirrer arm will provide a more dynamic movement so that the adhering soil will be removed from the surface of the sweet potato, as the washing water flows. The test results showed that the process of washing the sweet potatoes was successful, where the sweet potatoes that had dirt attached to them came off completely. The production capacity of the sweet potato washing machine is 50 kg, with a washing time of 5 minutes. The production cycle for a rotary system sweet potato washing machine is 15 minutes while manual washing is 40 minutes. Meanwhile, the productivity of rotary system washing sweet potatoes can reach 180 kg/hour. The production costs required for the equipment are IDR. 539,-/hour.

Abstract

This community service program implements swirl type microbubble generator (MBG) aerator technology to increase the productivity of koi fish farming in Kentong Village. The activity partner is Aim Koi Farm with a production capacity of 10,000 fish on 2 hectares of land. MBG technology works by producing micro-sized air bubbles (50-100 μm) through a swirl flow mechanism, which increases the surface area of ​​oxygen-water contact, thereby improving dissolved oxygen (DO) levels. Implementation begins with the installation of an aeration system, followed by measuring water quality parameters (DO, temperature, pH) using a water quality checker periodically for 30 days. Monitoring results showed a significant increase in DO levels from 4.2 ± 0.3 mg/L to 6.8 ± 0.4 mg/L (p<0.05). The positive impact was seen in a decrease in fish mortality by 15.2% and an increase in daily growth rate by 1.2 g/day. This program proves the effectiveness of MBG as an appropriate solution to increase the productivity of small-scale koi fish farming.

Abstract

Pertumbuhan ekonomi dan kemajuan teknologi akan menyebabkan tingginya penggunaan energi. Sebagian besar energi di dunia menggunakan sumber energi berbasis fosil, dimana penggunaannya menghasilkan emisi gas rumah kaca yang berdampak buruk pada lingkungan, seperti pemanasan global dan dampak negatif terhadap kesehatan manusia. Karenanya beberapa negara maju dan berkembang melakukan aksi dalam pembatasan penggunaan energi fosil dan mendorong pemanfaatan energi baru dan terbarukan yang lebih ramah lingkungan dan lebih berkelnajutan (sustainable). Diantara aksi tersebut adalah Paris Agreement pada tahun 2015 yang mendorong setiap negara melakukan kegiatan untuk menurunkan iklim global setidaknya 1,5°C – 2°C. Energi baru dan terbarukan adalah sumber daya energi alami yang dapat digunakan secara bebas, terus diperbaharui, tak terbatas, dan terus berkelanjutan. Hal-hal terpenting adalah terkait jenis, sumber, dan manfaat dari energi baru dan terbarukan. Kebutuhan manusia akan sumber daya energi tidak dapat diabaikan, karena setiap aktivitas memerlukan sumber daya, baik itu terbarukan maupun tidak. Namun, penggunaan sumber daya energi yang tidak dapat diperbaharui berlebihan telah menyebabkan kerusakan lingkungan alam yang serius dan akhirnya menghasilkan polusi yang berbahaya bagi Kesehatan manusia dan lingkungan. Dalam menghadapi keterbatasan sumber daya energi yang tak terbarukan, para ilmuwan dari berbagai negara telah mulai mengembangkan sumber daya energi baru dan terbarukan. Kegiatan pengabdian ini tidak hanya bertujuan untuk memperkenalkan konsep energi baru dan terbarukan, tetapi juga memberikan solusi konkret terhadap masalah sampah yang telah menjadi ancaman serius bagi lingkungan dan kesehatan masyarakat. Masalah sampah, khususnya limbah anorganik, telah menjadi salah satu isu utama yang dihadapi masyarakat modern. Setiap hari, tumpukan sampah kian menggunung, menciptakan dampak negatif yang signifikan, terutama ketika musim hujan tiba. Krisis ini tidak hanya berdampak pada keindahan lingkungan, tetapi juga berpotensi menyebabkan banjir yang melanda daerah pemukiman. Sampah anorganik, seperti plastik, tidak dapat terurai secara alami, sehingga memerlukan intervensi yang inovatif dan berkelanjutan. Sebagai respons terhadap tantangan tersebut, tim pengabdi mengembangkan teknologi mesin pencacah sampah anorganik yang revolusioner. Teknologi ini mampu mengubah limbah plastik menjadi serbuk atau biji plastik, sehingga memfasilitasi proses daur ulang yang lebih efisien. Dengan inovasi ini, kita tidak hanya mengurangi volume sampah, tetapi juga memberikan nilai tambah pada limbah yang selama ini dianggap sebagai masalah. Proses distilasi merupakan salah satu cara atau solusi untuk menghasilkan minyak hasil proses distilasi dengan metode pirolisis untuk bahan bakar cair dan ini menjadi salah satu sumber energi alternatif. Energi alternatif ini diperoleh dari sampah berbagai macam atau tipenya. Karena bahan bakunya berlimpah maka selain menjadi bahan bakar alternatif juga mampu menyelesaikan masalah sampah anorganik yang nyata tidak dapat diperbaharui dan dapat merusak tanah dan lingkungan.

Abstract

Argosari Village faces a critical waste management challenge due to the accumulation of biogas slurry (300–500 kg/day), household waste (687 kg/day), and agricultural waste (1,919.7 kg/day). Limited public awareness and waste processing capacity have led to uncontrolled environmental pollution. This community service program introduces the Octane Cycle Concept, a novel and integrative waste utilization model that transforms both organic and inorganic rural waste into valuable products such as compost, fertilizers, fish feed, mushroom media, and handicrafts. The Octane Cycle emphasizes a closed-loop, multi-output processing approach that links food, energy, and local economy in a zero-waste framework. The program was carried out in five phases: preparation, equipment provision, community training, monitoring and evaluation, and reporting. Results show that waste volume in Argosari Village was reduced by 51% within three months. In addition to improving environmental cleanliness, the program fostered entrepreneurship and increased household savings through the production of bio-based products. This model demonstrates the scientific and practical potential of applying circular economy principles at the village level.

Abstract

This community service program aimed to enhance community-based digital promotion capabilities for tourism managers of Suban Lesung, located in Talang Ulu Subdistrict, Curup Timur, Rejang Lebong Regency. The program was conducted over three months and involved ten local tourism management community participants. Initial field observations and pre-test results revealed a low level of understanding regarding digital promotion strategies, particularly in using Instagram Business features. A participatory training approach based on the Community-Based Training (CBT) model was implemented to address this, covering content planning, Instagram Business management, and targeted advertising through Instagram Ads. The evaluation was done using pre-test and post-test instruments, as well as an analysis of the @subanlesung account's digital performance. The results indicated a significant improvement in participants' understanding and the account's engagement metrics: a 36.27% increase in followers, over 100,000 content impressions, and notable audience growth especially among productive-age female users in Curup and Bengkulu. After the training, participants began independently managing content scheduling and production, including creating culturally inspired promotional materials. This initiative demonstrates that a structured, community-based digital training program can foster sustainable tourism promotion practices and empower local communities. The model also presents a scalable framework for similar rural destinations facing digital literacy and online branding challenges.
