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

Coffee is a vital plantation commodity for the Indonesian economy, yet the potential of Arabica coffee in Petang District, Badung Regency, remains underutilized due to a reliance on raw material sales that yield low added value. This study analyzes the current state of the Arabica coffee agroindustry and identifies internal and external factors to inform sustainable development strategies. Utilizing a mixed-methods approach with SWOT analysis and IFE/EFE matrices, data were collected through interviews, observations, and stakeholder questionnaires. The findings reveal that while the industry benefits from high product quality and ideal agroclimatic conditions, it is hindered by limited processing technology, restricted capital access, and weak branding. Consequently, the recommended strategies focus on enhancing post-harvest quality, strengthening farmer institutions, diversifying processed products, and integrating tourism-based marketing to boost the competitiveness and added value of Badung Regency’s Arabica coffee Contribution to Sustainable Development Goals (SDGs):SDG 6: Clean Water and SanitationSDG 11: Sustainable Cities and CommunitiesSDG 13: Climate Action

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.

Abstract

This study investigated the effects of Lemek Sari organic fertilizer and NPK Tawon inorganic fertilizer on the growth and yield of chili (Capsicum annuum L.). A randomized block design with a factorial arrangement was employed, incorporating five Lemek Sari doses (0, 10, 20, 30, 40 t ha?¹) and four NPK Tawon doses (0, 200, 400, 600 kg ha?¹). NPK Tawon fertilizer exerted highly significant effects (P < 0.01) on all measured growth and yield parameters. The optimum dose of 600 kg ha?¹ produced the highest fruit weight (202.37 g), representing a 2073.68% increase over the unfertilized control. Lemek Sari organic fertilizer applied independently had a significant effect solely on stem diameter (P < 0.05), whereas the 40 t ha?¹ dose elevated fruit weight by 90.07% relative to the control. A highly significant synergistic interaction (P < 0.01) was observed for the number of harvested fruits, with the combination of 40 t ha?¹ Lemek Sari and 600 kg ha?¹ NPK Tawon yielding the highest fruit number (34.67 fruits per plant), compared to zero fruits in the unfertilized control. Correlation analysis revealed near-perfect positive relationships (r > 0.90) among vegetative and generative parameters under NPK Tawon treatment, confirming that macronutrient supply acted as the primary limiting factor for yield formation. These findings demonstrate that soil improvement by high-dose Lemek Sari organic fertilizer maximizes the efficiency of NPK Tawon, providing a scientifically grounded strategy for sustainable intensification of chili production.

Abstract

This study aims to determine the effect of NPK Phonska Plus dosage, Lemesari organic fertilizer dosage, and its combination on the growth and yield of white eggplant (Solanum melongena L.). White eggplant has high economic potential in Bali, but its productivity is constrained by low soil fertility. The research was conducted in Cemagi Village, Badung Regency, using a factorial Random Block Design (RBD) with two factors: the dose of NPK Phonska Plus (0.200, 400, 600, 800 kg/ha) and the dose of Lemeksari organic fertilizer (0, 10, 20, 30 tons/ha). Preliminary soil analysis showed a very low C-organic content (1.75%). Data were analyzed using ANOVA and 5% LSD/DMRT tests. Answering the hypothesis, the results of the study show that the application of NPK Phonska Plus significantly affects the height of the plant, stem diameter, number of fruits, and weight of fruit, with 400 kg/ha being the optimal dose for physical aesthetics (length and diameter). Secondly, the application of Lemeksari organic fertilizer significantly increased the height of the plant and the weight of the fruit, confirming the hypothesis that a dose of 30 tons/ha provides the best response due to the improvement of soil structure. Finally, the interaction between the two fertilizers significantly affects the generative phase (the number of fruits and the weight of the harvest). The combination of NPK 400 kg/ha and Lemeksari 30 tons/ha is recommended as the most agronomically efficient treatment to optimize crop yields.
