Abstract

Giving probiotics such as probiotic boster on feed greatly helps the growth of absolute weight in Catfish seeds because the good bacteria contained in these probiotics help facilitate catfish seeds in digesting the feed so as to increase the efficiency of the feed. This study aims to see how effective the probiotic administration is. The study was conducted in Kramas District, Gianyar regency, Bali Province for 30 days using experimental methods, using a complete randomized design with a total of 4 treatments and 6 repetitions. Treatment A is by giving 3 ml of probiotic boster every 1 kg of feed. Treatment B by giving 5 ml probiotic boster every 1 kg of feed. Treatment C by giving 7 ml probiotic boster every 1 kg of feed. Treatment D by giving 9 ml probiotic boster every 1 kg of feed. In this study showed significantly different results on the addition of probiotic boster with different doses on the growth of absolute weight of catfish fry aged 1 month-2 months. Treatment D gave the highest result with an absolute weight gain of 55.33 grams, and treatment a showed the lowest result with an absolute weight gain of 25.17 grams. Water quality Data during the study obtained water temperature ranges from 27-29 oC, acidity ranges from 7-8, and dissolved oxygen ranges from 3.34 to 4.26 ppm. The results of the analysis of variance (ANOVA) of the three parameters of water quality there is no difference between the treatment and the life range of catfish fry (Clarias sp.)

Abstract

Vannamei shrimp is one of the shrimp species with economic value and is one of the national leading commodities. On the other hand, one of the problems in vannamei shrimp cultivation is its slow growth, slow growth is caused by the less optimal absorption of nutrients in the feed. In dealing with these problems, one of the things that is done is the administration of probiotics. The addition of probiotics such as Biolacto containing Lactobacillus sp bacteria to the feed can increase the appetite of shrimp. This study aims to determine the effect of biolacto probiotics on feed on the growth of the absolute weight of vannamei shrimp. This study used a Complete Random Design (RAL) with four treatments: A (feed without a mixture of probiotics), B (probiotics 2 gr/100 gr feed), C (probiotics 4 gr/100 gr feed), and D (probiotics 6 gr/100 gr feed). Treatment B with a concentration of probiotics 2gr/100g feed gave the highest absolute weight growth of 9.2 gr. Water quality data during the study were obtained with water temperature ranging from 28.5 – 29.2°Celsius, salinity ranging from 36 – 37 ppt, pH ranging from 7.5 – 8.0, and dissolved oxygen ranging from 4.0 to 4.63 mg/l. The results of the ANOVA analysis of the four water quality parameters showed no difference between treatments and were in the optimal range of life of vannamei shrimp (Litopenaeus vannamei).

Abstract

The use of probiotics is very important in cultivation activities. Probiotics are live microorganisms that have a beneficial effect on the host by balancing the microflora in their intestines. In increasing the nutritional content of artificial feed (pellets), the bacteria in probiotics have a mechanism for forming several enzymes for digesting feed. This study aims to determine the effect of giving delacto probiotics at different doses in artificial feed on the absolute weight growth of tilapia (Oreochromis niloticus). Probiotics are mixed with feed using a biofloc cultivation system. The method used in this research was an experimental method with a Completely Randomized Design (CRD) with 4 treatments and 6 replications, namely by adding different doses to the treatments. Treatments A (8ml/kg), B (16 ml/kg), C (24 ml/kg) and D (32 ml/kg). The parameter observed was absolute weight growth. Water quality supporting parameters include temperature, pH and DO. Data were analyzed using the ANOVA test. Based on the research results, it shows that giving different doses of delacto probiotics has a significant effect on the absolute weight growth of tilapia (Oreochromis niloticus). Treatment A (8 ml/kg) gave the lowest absolute weight growth of 32.83 grams and treatment D (32 ml/kg) gave the highest absolute weight growth of 40.57 grams. Water quality parameters include water temperature ranging from 25.3 – 26.1֯C, acidity ranging from 7.5 – 8.0. And dissolved oxygen ranges from 4.7 – 5.3 ppm. The results of analysis of variance (ANOVA) for the three water quality parameters showed no differences between treatments (Oreochromis niloticus) fry.

Abstract

This study aims to analyze the effect of the Human Development Index (HDI), economic growth, and the open unemployment rate on poverty levels in Tuban Regency during the period 2010–2024. This research uses a quantitative approach with multiple linear regression analysis and secondary data obtained from the Central Statistics Agency and other relevant institutions. The results indicate that HDI has a negative and significant effect on poverty, demonstrating that improvements in education, health, and living standards contribute significantly to poverty reduction. Meanwhile, economic growth and the open unemployment rate show positive but insignificant effects on poverty levels. These findings indicate that economic growth has not been optimally distributed among communities, while the dominance of the informal sector in the labor structure causes unemployment to have limited direct influence on poverty conditions. Simultaneously, HDI, economic growth, and the open unemployment rate significantly affect poverty levels in Tuban Regency. Therefore, effective policies emphasizing human resource development, employment improvement, and inclusive economic growth are required to accelerate poverty alleviation. This study provides important insights for local governments in formulating sustainable development strategies to reduce poverty through improving community welfare and economic equality.
