Abstract

This study aims to determine the ability of Trichoderma atroviride and Gliocladium sp. in inhibiting the fungus that causes Gumosis disease Botryodiplodia theobromae. This study used a completely randomized design with two single treatments and was repeated eight times. In the in-vitro antagonism test Trichoderma atroviride and Gliolcadium sp. can inhibit the fungus Botryodiplodia theobromae as well. The percentage of inhibition was 94.58% in the Trichoderma atroviride antagonism test and 81.67% in the Gliocladium sp. antagonism test. Whereas the Botryodiplodia theobromae Colony Area had no significant effect on both treatments. Each Botryodiplodia theobromae Colony area is 18.34 cm2 with T. atroviride treatments and 22.25 cm2 with Gliocladium sp. treatment. The growth rate of Botryodiplodia Theobroma fungi was superior to that of Trichoderma atroviride and Gliocladium sp.

Abstract

Tomato is an important vegetable crop and has been widely cultivated as a garden plant or commercially. The purpose of this study was to measure the effectiveness of organic fertilizer based on coal and cow dung based on several tomato varieties. This study used a factorial randomized design with two factors, namely the type of fertilizer consisting of "Saputra" coal fertilizer (BB), "Bio Alam Asri" manure (BA) and without organic fertilizer (B0); and the other factor is the tomato variety factor (V), namely Servo F1 (VS), Gustavi F1(VG), and Fortuna 23 (VF). Based on the results of the study, it was found that the treatment of BB and BA, in general, had a significant effect on vegetative growth and generative yields including fruit quality in the three tomato varieties tested. The highest number and fresh weight of tomatoes per plant were obtained in the treatment of BB, namely 44.00 fruits and 3.00 kg, higher than BA fertilizer, namely 39.11 fruit and 2.62 kg, and B0 namely 34.00 pieces and 2.20 kg. The highest number and fresh weight of tomatoes per plant were obtained in VS varieties, namely, 42.33 fruits and 2.74 kg, followed by VG varieties at 40.11 fruits and 2.71 kg and the lowest was VF at 34.67 fruit and 2.38 kg. The highest vitamin C content of fresh fruit was obtained in the BB treatment, which was an average of 36.75 mg/100g, higher than the treatment with BA fertilizer and B0, which were 32.81 mg/100g and 31.07mg/100g.

Abstract

The pumelo population in Bali is declining one is caused of a lack of good-quality seeds. This research was conducted to determine the effectiveness of organic coal fertilizer and rabbit farm waste as organic fertilizers for the growth of pomelo grafting seedlings. The research design used a nested pattern randomized block design with 3 replications. There are two factors, the first factor is the type of fertilizer, which are Coal fertilizers, Rabbit Farm Waste fertilizers, and Cow Manure fertilizers. The second factor is the dose of each type of fertilizer which consists of 3 levels, namely: 10 tons/ha; 20 tons/ha; and 30 tons/ha. The results showed that the effectiveness of the treatment of the type of organic fertilizer and the dose of the type of organic fertilizer had no significant effect on all observed variables. This shows that both coal fertilizer and rabbit manure have almost the same quality as cow manure in influencing the growth of pomelo seedlings. The effectiveness of fertilizers tested on the average shoot length of grafting tends to show the highest yields obtained at the highest dose (30 tons/ha), namely Coal fertilizer which is 28.80 cm, rabbit manure is 31.87 cm, and cow manure obtained is 28.13 cm.

Abstract

This study analyzes the marketing strategies for cayenne pepper in Badung Regency, Bali, to support government policies aimed at enhancing horticultural competitiveness and farmer welfare. Conducted in the production centers of Mengwi, Abiansemal, and Petang, the research utilized a mixed-methods approach incorporating Internal Factor Evaluation (IFE), External Factor Evaluation (EFE), and Internal-External (IE) matrices, followed by a SWOT analysis. The results position the cayenne pepper agroindustry in Quadrant I (Strength–Opportunity), signifying robust internal capabilities and significant market potential. With an IFE score of 2.820 and an EFE score of 2.870, the study identifies high product quality and rising market demand as primary drivers, while production fluctuations and price uncertainty remain key challenges. To optimize this potential, the study recommends a multi-faceted strategy: stabilizing production through strengthened farmer groups, launching chili subscription programs for culinary businesses, and utilizing digital platforms. Furthermore, establishing weekly farmers' markets, fostering partnerships with supermarkets, and diversifying processed products are essential to stabilizing supply and improving the economic welfare of local farmers.
