Abstract

Abstrak- Biogas merupakan salah satu sumber energi alternatif yang sedang dikembangkan dan sumber energi yang terbarukan. Bahan baku yang digunakan adalah kulit jeruk busuk (Citrus sinensia osbeck) dan kobis (Brassica oleracea). Penelitian ini bertujuan untuk mengetahui pengaruh volatile solid dan limonen terhadap produksi biogas. Penelitian menggunakan erlenmeyer 500 mL sebanyak 6 buah, waterbath, manometer air, dan thermometer. Volume total digester 350 mL. Penelitian dilakukan dengan cara menghancurkan bahan baku supaya lebih mudah didegradasi oleh bakteri. Oksigen yang bersifat toxic bagi bakteri anaerobik, dapat dihilangkan dengan penambahan N2 dalam digester pada awal operasi. Penelitian dilakukan pada kondisi mesofilik (30 – 400C) selama 50 hari. Hasil penelitian menunjukkan bahwa pada digester yang memiliki VS sama (T1 dan T3 dengan 15% VS, dan T2 dan T4 dengan 20% VS), dengan konsentrasi kulit jeruk/limonen berbeda (T1= 114ppm< T3= 170ppm, dan T2= 152ppm<T4= 225ppm), maka digester dengan konsentrasi kulit jeruk/limonen yang lebih tinggi akan menghasilkan asam asetat lebih tinggi pada setiap minggunya. Akumulasi asam asetat pada fase acethogenesis menyebabkan bakteri methanogen tidak dapat tumbuh dengan optimum pada fase berikutnya (methanogenesis). Pada kondisi yang sama, digester yang memiliki konsentrasi kulit jeruk/limonen yang lebih besar (T1<T3, and T2<T4) akan menghasilkan volume biogas yang lebih besar (T1= 54.963 cm3<T3= 46.372 cm3, T2= 60.314 cm3<T4= 69.191 cm3). Pada konsentrasi kulit jeruk/limonen 114ppm, diperoleh metana dengan kadar 0.1298%V/grVS. Kata kunci: Biogas, digester anaerobic, kulit jeruk, limonen.   Absrtact- Biogas is one of alternative energy resources that is being developed and renewable. The raw material that use were rotten orange (Citrus sinensis osbeck) and cabbage (Brassica oleracea). This research aimed to know influence of volatile solid and limonene the biogas production from fruit and vegetable waste. This research used 6 unit of Erlenmeyer 500 mL, waterbath, water manometer, and thermometer. Total volume of the digester was 350 mL. Adjusment of the pH in the start up was done to make the optimum condition for pH grow of methanogen (6,8 – 7,8). Toxicity of oxygen could be healed by spraying N2 in the digester in the beginning. The research was done under mesophilic conditions (30 – 40)0, during 50 days. The results showed that digester that has same VS (T1 and T2) with 15% VS, T2 and T4 with 20% VS) with different concentration of rotten orange/limonene (T1=114ppm<T3=170ppm, and T2=152ppm<T4=225 ppm), hence digester with higher concentration of orange peel/limonene will produce higher acetic acid every week. Accumulation of acetic acid in acidogenesis phase because of the limonene caused the methanogen bacteria cannot grow in the next phase (methanogenesis). At the same conditions, the volume of biogas that has higher concentration of rotten orange/limonene (T1<T3, and T2<T4) will produce higher accumulation of biogas volume (T1=54.963cm3<T3=46.372 cm3, T2=60.314 cm3<T4=69.191 cm3). At concentration of rotten orange/limonene 114 ppm, would obtain 0.1298%/grVS of methane concentration. Keywords: Biogas, anaerobic digestion, orange peel, limonene

Abstract

The purposes of this study were to observe and analyze the water level variations of the culture media that were optimal for egg hatchability and larval survival of kelabau fish kept in aquarium. This study was conducted in the Freshwater Aquaculture Development Centre (FADC) Banjar Regency in August 2015. The method used in this study was experimental, using a completely randomized design with 3 treatments (A = water level of 15 cm/aquarium), (B = water level of 25 cm/aquarium), (C = water level of 35 cm/aquarium) and 3 replications. The parameters measured in this study were the egg hatchability, survival rate, relative growth rate, and water quality (temperature, pH, DO, Ammonia). Data were analyzed by Anova and the differences between treatments were tested with Duncan test. The results showed that the water level very significantly affected the egg hatchability with the highest value in B (38.29%) followed by C (31.83%) and A (14.04%). The highest survival rate was in C (79.73%) followed by B (65.10%) and A (21.83%). The relative growth rate had not significant effect with the average results between all treatments (104.92 – 117.27%). The water quality of the culture media was still good to support the growth and survival of fish.

Abstract

The flood disaster that hit South Kalimantan in 2021 resulted in most fish cultivators not being able to raise fish in floating net cages again because they did not have much capital. Some fish cages that are still cultivating tilapia in floating net cages have very slow growth. The purpose of this PDWA activity is to increase knowledge and skills, meet the nutritional needs of families, and increase the income of members of the group of partner mothers in Awang Bangkal Timur Village, Banjar Regency, South Kalimantan. Activity Method (1) Extension and discussion. (2) Demonstration and participation. (3) Training and mentoring, and (4). Evaluation. The results of the PDWA activity were quite successful, namely from the demonstration plot of male monosex tilapia cultivation with artificial feeding for 3 months showed quite rapid growth. The average growth rate of tilapia is 240.3 grams kept for 3 months in a round pond, so this pilot can clearly prove to mothers, especially the target audience, that male monosex tilapia that is kept can be used as an effort to increase family income. . The final weight of the tilapia population was 237.975 kg with the amount of feed given for 3 months of 450 kg. Thus the feed conversion is 1.89. The evaluation value of the level of knowledge before explaining the theory averaged 8.47, after explaining the theory there was a significant increase in value, which was an average of 25.82. The results of data analysis showed that there was a change in the level of knowledge and skill level of the community regarding the technology of male monosex tilapia cultivation. The conclusions of the activity were (1) There was an increase in the knowledge of the partner group mothers regarding the technology that was presented. (2) There is an increase in the skills of partner group mothers after a demonstration or pilot is carried out.
