Optimization of the Octane Cycle Concept as an Integrated Waste Management Strategy Toward a Zero Waste Village in Argosari, Malang

Musyaroh — 2025-05-31

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.

Drajat Indah Mawarni — 2025-05-31

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.

Leveraging Smart Energy Meters for Precise Electricity Consumption Monitoring in Healthcare Facilities

Novalio Daratha — 2025-05-31

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.

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.
