Abstract

The heterosis and heterobeltiosis values ​​are genetic parameters that can be used to determine superior hybrid candidates. The heterosis value is calculated by comparing the F1 hybrid  with mid parent heterosis and best parent heterosis. This study aimed to determine the heterosis and heterobeltiosis values ​​of 29 melon genotypes. The genetic material used in the research was 29 melon genotypes. The research used a single factor Complete Randomized Block Design with three replications. The characters observed were stem diameter, leaf length, harvest age, fruit length, fruit diameter, fruit weight, fruit flesh thickness, and fruit sweetness level. Genotypes that produced high heterosis and heterobeltiosis values ​​were G29xG4 for fruit length, fruit diameter and fruit weight, G9xG4 for fruit length, fruit diameter and fruit flesh thickness, G29xG9 and G38xG4 for fruit length and fruit sweetness, G4xG38 for fruit fruit length and flesh thickness, G29xG40 for fruit weight and fruit flesh thickness, and also G40xG4 and G38xG40 for fruit weight.

Abstract

The development of feed technology with the fortification of silkworm flour (Tubifex sp) is one solution that can be attempted. The silkworm contains high protein. This study aimed to analyze the effect of fish feed fortification with silkworm flour on the growth phase of Sangkuriang catfish. This research method used a Completely Randomized Design on one factor with three replications. The factors used were four treatments including A (95% fish flour + 5% silkworm flour), B (90% fish flour + 10% silkworm flour), C (85% fish flour + 15% silkworm flour), and D (80% fish flour + 20% silkworm flour). The results showed that the rate of length increase and weight increase of Sangkuriang catfish significantly increased when the catfish were in the 20-day enlargement phase in the tarpaulin pond. Treatment C (85% fish meal + 15% silkworm meal) was the best feed formulation seen in the high absolute weight growth (23,67 g), daily growth rate (2,66%), and feed utilization efficiency (1,32%). The results of this study can used as a reference in making artificial feed for the enlargement of Sangkuriang catfish.

Abstract

Fish meal is the main raw material used for feed because it contains high protein. Currently, the fulfillment of fish meal is still supplied from abroad. Indonesia imported 121 thousand tons of fish meal in 2023. This has an impact on the expensive price of feed. In addition, fish meal is produced from fishing in the sea which threatens the sustainability of the fish population. Maggot meal and mustard waste meal as local resources can be a solution in fulfilling alternative protein sources as sustainable fish feed ingredients. The study aimed to evaluate the growth response of tilapia to the effect of adding fish feed ingredients from maggot meal and mustard waste meal. The study used a single factor Completely Randomized Design with four treatments namely, P1: 75% fish meal + 12.5% ​​maggot meal + 12.5% ​​mustard waste meal, P2: 50% fish meal + 25% maggot meal + 25% mustard waste meal, P3: 25% fish meal + 37.5% maggot meal + 37.5% mustard waste meal, P4: 0% fish meal + 50% maggot meal + 50% mustard waste meal. The results showed that the provision of artificial feed based on maggots and mustard waste treatment P4 (0% fish meal + 50% maggot meal + 50% mustard waste meal) provided the best growth performance of tilapia with a daily growth rate of 2.13%, an absolute length of 2.61 cm, an absolute weight of 5.19 g, a percentage increase in length of 32.49% and 100% survival.

Abstract

The study aimed to observe the growth and yield of sweet corn in organic and inorganic cultivation systems. The experimental design in the study used a completely randomized block design with three replications. The treatments consisted of organic and inorganic cultivation systems. Observations included variables on growth components and yield components. Observation data were analyzed statistically using the t-test (Paired Two Sample for Means at P < 0,05). The results showed that sweet corn fertilized organically and inorganically had the same effect on growth components (plant height, stem diameter, number of leaves, leaf length, leaf area, and leaf greenness) and yield components (cob height, cob length, and cob diameter with husks, cob length, cob diameter, and cob weight without husks, number of rows in the cob and number of seeds per row). Farmers can use the results of this study to choose fertilizers for cultivating sweet corn.

Abstract

The development of fish feed fortification technology based on agricultural waste is one of the potential solutions to reduce feed production costs. Fish feed fortification can be derived from animal and plant sources, provided that the fortification ingredients contain protein, carbohydrates, fat, and other nutrients. Rice bran, an agricultural by-product, contains carbohydrates that can be utilized as raw material in fish feed formulation. The objective of this study was to analyze the effect of fortified fish feed made from silk worm meal and fish meal fortified with rice bran waste on the growth and yield of Sangkuriang catfish (Clarias gariepinus). The research method employed a Completely Randomized Block Design (CRBD) with four treatments, namely: A (2.25% tapioca flour + 0.75% rice bran flour), B (2% tapioca flour + 1% rice bran flour), C (1.5% tapioca flour + 1.5% rice bran flour), and D (0.75% tapioca flour + 2.25% rice bran flour). Each treatment was replicated three times, resulting in a total of 12 experimental units. The results showed that treatment D (0.75% tapioca flour + 2.25% rice bran flour) was the best artificial feed formulation for Sangkuriang catfish grow-out, as indicated by higher absolute length gain, absolute weight gain, survival rate, and feed conversion ratio. The nutritional content of treatment D feed formulation (1:3), consisting of 0.75% tapioca flour + 2.25% rice bran flour, was 1.85% carbohydrate, 12.79% fat, and 31.01% protein.

Abstract

In recent years, the use of natural and local ingredients to improve the nutritional quality of feed, as well as fish health and growth, has required the addition of supplementary components such as phytobiotics and carbohydrates. The abundance of local ingredients like papaya leaves and cassava in the Bengkulu region presents great potential for their utilization as feed supplements for fish. This study aimed to evaluate the effect of combining phytobiotic and carbohydrate supplementation on the growth performance of Nile tilapia. The experimental design used was a Completely Randomized Design (CRD) with a single factor and four treatments: A (basal diet), B (basal diet + 25% papaya leaf meal + 75% cassava meal), C (basal diet + 50% papaya leaf meal + 50% cassava meal), and D (basal diet + 75% papaya leaf meal + 25% cassava meal). Each treatment was replicated three times, resulting in a total of 15 experimental units. The results showed that diet formulation D (basal diet + 75% papaya leaf meal + 25% cassava meal) was the best treatment, as it produced the highest feed intake, better daily growth rate and biomass, and a relatively greater absolute length compared to the other treatments.
