Abstract

In the last three years, the production of melon has decreased. The decline in melon production was caused by the limited availability of superior seed varieties. Therefore, increasing production by developing superior varieties with high yields is necessary. Characterization is the first step in breeding plants. The research objective was to determine the characteristics of 21 melon genotypes. The research was conducted from January to March 2024. The research was conducted in Lubuk Saung Village, North Bengkulu Regency, Bengkulu Province. The experiment used a randomized complete block design on one factor with three replications. The factors used were 21 melon genotypes. The results showed that cluster analysis with a similarity of 33.33 produced five groups of melons, and G15 was the most different genotype among the other genotypes. Medium leaf size and medium green leaf color are the most dominant sizes and colors. The length of the leaf lobes in the medium category and the development of the leaf lobes in the weak category are the most dominant. The round shape of the fruit is the most common form of fruit. The skin color of the fruit before it is ripe is most green, and the color of the flesh when it is ripe is most white. Fruit without grooves is the most dominant, and surface wrinkles in the fragile fruit are the most dominant. Based on the characterization results, the next stage is selecting new superior varieties according to the desired characteristics.

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

National melon production has decreased from 2021 to 2023. One means to overcome this decline is through the expansion of planting areas. The potential of lowland areas can be optimized to enhance melon production. The development of melon varieties in lowlands relies heavily on the availability of germplasm. Genetic diversity within germplasm is a key prerequisite for producing adaptive and high yielding varieties. This research aims to identify melon genotypes with optimal growth and yield performance in lowland areas. The study was conducted at the Arga Makmur experimental farm, North Bengkulu Regency, from January to March 2024, at an altitude of 203.9 meters above sea level. The experiment used a single-factor Randomized Complete Block Design (RCBD) with 17 melon genotypes as treatments and three replications. Data were statistically analyzed using the F-test, and significant genotypic treatments were further evaluated using the Duncan Multiple Range Test at a 5% significance level. The results identified five selected melon genotypes based on high fruit weight, fruit diameter, and sweetness level: genotypes G3, G4, G7, G12, and G17.

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.
