Application of Swirl Type Microbubble Generator Aerator Technology in Koi Fish Farming Business in Kentong Village: Penerapan Teknologi Aerator Microbubble Genertor Tipe Swirl pada Usaha Tambak Ikan Koi Desa Kentong
Get PDFThis 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.Desa Kentong terletak kurang lebih 5 kilometer dari Sekolah Tinggi Teknologi Ronggolawe (STTR) Cepu.

Optimalisasi Konsep Octane Cycle sebagai Strategi Pengolahan Sampah Terpadu Menuju Desa Zero Waste di Argosari, Malang: Optimalisasi Konsep Octane Cycle sebagai Strategi Pengolahan Sampah Terpadu Menuju Desa Zero Waste di Argosari, Malang
No full textArgosari 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

Sport Injury and Physiotherapy Services in Indonesian Paralympic Athletes at The Asean Paragames in Cambodia 2023
Get PDFThe ASEAN Paragames Cambodia 2023 was attended by 268 Indonesian paralympic athletes, the largest number compared to the Tokyo 2020 International Paralympic Games with 23 Indonesian paralympic athletes. Paralympic athletes have a higher prevalence of injuries compared to Olympic athletes. Injuries in paralympic sports vary due to the large percentage of disability. However, there is no literature that specifically describes the frequency and percentage of sports injuries in the categories and areas of sports injuries in the region and physiotherapy services in Indonesian paralympic athletes. The method used was a retrospective descriptive epidemiological study with a cross-sectional approach. This method aims to determine the frequency and percentage of sports injuries in sports categories and affected anatomical areas and types of physiotherapy services in a population at one time without making comparisons or connecting between variables. The sports category of Indonesian Paralympic athletes with the highest number and percentage of injuries was Para Athletics (n=57.35.2%). In the category of the area anatomically affected by the injury, the highest number and percentage was the leg (n=36.22.2%). Physiotherapy services provided to paraathletes with the highest number and percentage was stretching (n=77.19.2%). The high frequency of sports injuries in paralympic athletes indicates that more prevention needs to be done in the future, injuries that occur in paralympic athletes can aggravate existing disabilities and can even interfere with the athlete's ability to carry out daily activities, therefore physiotherapy services are needed to support the handling of injuries in paralympic athletes during competition
