Abstract

Cooking oil is one of the primary ingredients that must be available for the household needs of Indonesians. Population growth, industrial development, restaurants, and fast-food restaurants cause the use of cooking oil to increase. The increase in the use of cooking oil will cause an increase in frying waste. Waste cooking oil that is not managed properly will cause pollution. Lack of public awareness of the dangers of waste cooking oil to the environment so there is a need for guidance to the community regarding the dangers of disposing of used cooking oil waste into the environment and providing solutions for the use of waste cooking oil in new products that have economic value. Therefore, as a community service from the Institute of Science and Technology of Nahdlatul Ulama Bali (ISTNUBA), we try to invite the community in Banjar Anyar Village, Kediri, Tabanan Regency, Bali to be able to participate in training on processing waste cooking oil into bar washing soap and aromatherapy candles. The method is counseling and distribution of brochures about the dangers and benefits of waste cooking oil. This training activity is expected to increase public knowledge and awareness of managing waste cooking oil and can open up entrepreneurial opportunities, create jobs and improve the living standards of the surrounding community.

Abstract

Aquaculture is the fastest growing food production sector in the world. Snakehead fish (Channa striata) is one of the freshwater fish commodities in Indonesia which is still widely cultivated. Snakehead fish (Channa striata) is a fish that is economically feasible and has benefits that are beneficial to human health. This research was conducted in a period of 58 days aimed to determine the effect of feeding maggot BSF (Hermetia illuences) on the growth and survival of snakehead fish (Channa striata). The stocking density of fish in this study was 20 fish/pond, 3-4 cm in size fish obtained from cultivators in the Denpasar area, the pond used was made of tarpaulin with a size of 50×50 cm. This research used 3 treatments, treatments A (100% pellet), treatment B (100% BSF maggot), and treatment C (50% pellet + 50% BSF maggot) with 3 replications. Parameters observed in this study were specific growth rate, absolute length growth, survival rate, feed conversion ratio and water quality. The results of the research that have been carried out show that treatment C gave the highest yield on the specific growth rate, absolute length growth and survival rate of snakehead fish (Channa striata). The results of water quality measurements show that the temperature ranges from 29.32-30.18oC, pH values ??range from 6.50-5.52, and DO ranges from 2.79-2.90 mg/L, the water quality value is still in the optimum value range for maintenance of snakehead fish (Channa striata).

Abstract

Swordfish (Trichiurus lepturus) with the local name Layur is one of the demersal fish commodities that has high economic value because it is an export commodity with high omega 3 content.. The high demand for layur fish must be supported by good fish quality and quality. The quality control is needed related to fish diseases, one of which is fish parasites. Endoparasite infection in marine fish can be zoonotic and dangerous if consumed by humans. This research was conducted to determine the intensity, prevalence, abundance and correlation of fish sex with the number of endoparasites. The research sample was obtained from the Kedonganan Fish Market, Bali which was held from September 2022 to November 2022. The sampling method was carried out by purposive sampling by paying attention to the secondary sexual characteristics of the swordfish. The total sample of fish examined was 36 fish consisting of 18 male fish and 18 female fish. Endoparasites of the genus Acanthobothrium were parasites with the highest intensity and abundance values, namely 46.05 ind./fish and 28.14 ind./fish, while the highest prevalence value was obtained from the Genus Lecithochirium of 86.11%. The correlation between fish sex and the number of endoparasites was analyzed using the Mann – Whitney test with an Asymp value. Sig 0.506 and Z value -0.665. These results showed an insignificant relationship (p > 0.05) between the sex of the fish and the number of endoparasites in the whitefish that were sampled in this study.

Abstract

Batukaru Temple Cultural Reserve is one of the Kahyangan Jagat (State Temple) in Bali, and its area has been designated by UNESCO (2012) as one of the World Cultural Heritage of Bali. This study aims to reveal the meaning of the ritual of asking for rainwater (pakelem ritual) for traditional farming communities (subak) in the Batukaru Cultural Heritage Area of Tabanan Regency. The study was conducted by collecting data through observation, interviews, and literature study. The collected data were analyzed descriptively qualitatively using the cultural ecology approach. Successively, sacrificial rituals and offerings (mapag/mendak toya rituals) are performed every year. In the pakelem/pangeleb ritual at Lake Tamblingan, the sacrificial means offered is sudamala buffalo (kebo ius merana). The implementation of the mendak toya and pakelem rituals every year in different places implicitly represents the knowledge of farming communities (subak) related to natural ecosystems that are interdependent, namely in particular water ecosystems related to climate (rainfall), mountain and forest ecosystems (wana-giri), watersheds and lake ecosystems. Implicitly these rituals reflect the awareness of the farming community (Subak) on the importance of water resources for agricultural life and other interests.

Abstract

Tilapia is a type of fish favored by freshwater fish consumers because it is easy to cultivate. The problem faced in freshwater fish farming activities is the high price of artificial feed. To deal with these problems, alternative feeds are needed to reduce the use of artificial feeds such as sudden apu wood (Azolla pinnata). This study aims to determine the effectiveness of the sudden apu wood (Azolla pinnata) on the growth and survival of tilapia (Oreochromis niloticus) and to help fish farmers reduce the use of artificial feed. The research method used is an experimental approach method. The experimental design in this study was a Randomized Block Design (RAK) which consisted of 3 treatments with 3 replications. Treatment A (direct feeding of 100% Azolla pinnata plants), Treatment B (direct feeding of 50% Azolla pinnata plants and 50% pellets), and Treatment C (100% pellet feeding). The results showed the absolute weight growth of treatment A 12.18±5.66 g, treatment B 17.73±4.40 g, treatment C 24.53±3.80 g. The absolute length growth of treatment A was 2.22 ± 0.60 cm, treatment B 2.54 ± 0.40 cm, treatment C 3.50 ± 0.37 cm. The survival rate of treatment A was 66.67±11.54%, treatment B and treatment C were 100±0%. Feed conversion ratio (FCR) for treatment A 4.8±2.28, treatment B 2.1±0.45, treatment C 1.7±0.17. The water quality of the three feeding treatments had no significant effect on pond water quality and was still within the optimal range for tilapia growth and cultivation.

Abstract

Community participation determines the success of source-based waste management in Baktiseraga Village, which is waste management carried out in the village itself, so that no more waste is sent to the landfill. TPS 3R supports the sustainability of waste management that has been formed as many as 13 household waste collection networks to convey to the community to start sorting waste both organic and inorganic. This research uses qualitative methods, through data collection techniques with observation (participatory observation) and interviews (indept interviews), document studies and literature studies. To produce a thick description, interpretative descriptive analysis is used, which describes community participation regarding source-based waste management, through the implementation of the TPS 3R program. The purpose of this study was to determine, identify, understand and reveal community participation in source-based waste management, through the implementation of the reduce-reuse-recycle waste management site (TPS 3R) in Baktiseraga Village, District / Buleleng Regency. This research shows that the implementation of TPS 3R in Baktiseraga Village is an effort made to support the sustainability of waste management that has previously been formed. There are thirteen networks of household waste collectors formed to convey to the community to be able to sort organic and inorganic waste independently.
