Abstract

Chili pepper (Capsicum frutescens L.) is a plant commonly cultivated in Indonesia. This research employed an empirical, quantitative experimental approach using a Randomized Block Design (RBD). The study included three treatment groups with varying concentrations of cigarette butt biopesticides: a control group, and treatment groups at 10 ml/L, 20 ml/L, and 30 ml/L. The results indicated that biopesticides derived from cigarette butt waste extracts significantly affected the control of whitefly pests on chili peppers. The ANOVA test yielded an F value of 150.044 with a significance level of 0.000, demonstrating a highly significant difference among the treatments. The control group exhibited the highest average mortality rate of 62.22% for pests, followed by the 10 ml/L treatment at 50.67%, the 20 ml/L treatment at 42.67%, and the 30 ml/L treatment, which was the least effective, with an average mortality rate of 32.00%. These findings suggest that higher concentrations of the extract are more effective in reducing the number of living pests, positioning this biopesticide as an environmentally friendly alternative for pest control.

Abstract

Soil health is a crucial factor in the sustainability of Arabica coffee production, particularly in addressing the challenges of land degradation caused by conventional agricultural practices. One practical approach to naturally enhance soil fertility is implementing a regenerative farming system, which focuses on increasing the diversity of soil microbes to support a healthy and productive ecosystem. This study aims to analyze and compare the diversity of soil microbes in Arabica coffee fields managed under regenerative farming systems versus those under conventional farming systems. It will identify the dominant types of microbes in each system and examine how their presence influences soil fertility. Additionally, the study will assess the impact of regenerative farming on the balance of the soil microbial ecosystem and the health of coffee plants. The methodology employed is comparative, involving soil sampling through random sampling techniques. Microbial diversity will be analyzed using culture methods, with soil microbial observation parameters including bacteria, fungi, phosphorus-solubilizing bacteria, nitrogen-fixing bacteria, respiration rates, and the carbon-to-nitrogen (C/N) ratio. Laboratory data will be analyzed using comparative statistical tests, specifically the t-test. The study aimed to identify microbial distribution patterns using PCA-Bi Plot analysis. The results indicated that the total number of bacteria, fungi, total microbes, and soil respiration rates were significantly higher in the regenerative farming system than in the conventional system. The dominant soil microbes in the regenerative farming system included nitrogen (N) fixing bacteria and decomposer fungi. A strong positive correlation (r = 0.938, p < 0.01) was observed between total microbes and soil respiration. The regenerative farming system not only increases the number of soil microbes but also enhances the biological activity of the soil. These findings underscore the potential of regenerative agriculture as a viable alternative for improving soil quality in Coffea arabica cultivation, aligning ecological benefits with agricultural productivity.

Abstract

Gembili tuber (Dioscorea esculenta L.) is a tuberous plant known for its high nutritional value and richness in bioactive compounds. These bioactive compounds, including diosgenin, β-sitosterol, and saponins, offer various health benefits, such as antimicrobial, anticancer, and antioxidant properties, crucial in preventing degenerative diseases. This study aims to investigate the differences in phytochemical and antioxidant content of Gembili tubers from different locations. The research was conducted at the Phytochemical Laboratory, MARDI, in Selangor, Malaysia, where the total phenolic content (TPC) was analyzed using the Folin-Ciocalteu method, and the antioxidant capacity was assessed through the DPPH (2,2-diphenyl-1-picrylhydrazyl) assay using a UV spectrophotometer (Eon Biotek) at 517 nm. The results indicated that the total phenolic content and antioxidant values of yam bean tubers from the Serdang location in Selangor were higher than those from the Port Dickson location in Negeri Sembilan, measuring 1.6940 mg GAE/100g and 0.366 mg/ml in the DPPH test, respectively. Consequently, yam tubers cultivated in Serdang, Selangor, demonstrate greater potential as a source of natural antioxidants beneficial for health than those grown in Port Dickson.

Abstract

Gac fruit is renowned for its rich content of bioactive compounds, including lycopene, β-carotene, and vitamin E, which provide significant health benefits. However, due to its high moisture content, the fruit is highly perishable and requires proper postharvest handling to extend its shelf life. Drying is one of the most common preservation techniques employed to retain nutritional and functional qualities while reducing water activity. This study aims to evaluate the influence of different drying methods, specifically oven drying, vacuum drying, and sunlight drying. The results indicate that vacuum drying exhibits the highest IC50 inhibition compared to both solar and oven drying methods; however, there is no significant difference in inhibition between the solar and oven drying methods. In lightness (L value), sunlight and vacuum drying result in darker colors than oven drying. Still, there is no significant difference in brightness between sunlight and oven drying. The solar drying method exhibited the highest weight loss at 87.45%. However, there was no significant difference in the drying efficiency between the oven and vacuum oven methods. Microbial contamination under sunlight appears to be higher than in oven and vacuum drying; nonetheless, all methods remain acceptable as they fall below the safe limit. Based on these results, oven drying was selected for Gac fruit drying due to its favorable physicochemical outcomes and the shortest drying time. Additionally, oven drying proved to be the most balanced method, providing good retention of bioactive compounds, effective moisture removal, and acceptable microbial stability. Furthermore, oven drying produced the most visually appealing red hue, likely attributed to enhanced lycopene stability.

Abstract

Quality seeds are crucial for successful sweet corn production. Various factors influence seed quality, including harvest time and initial water content. Therefore, understanding the interaction between harvest time and initial water content is essential for optimizing the quality of sweet corn seeds. This study aims to determine the optimal harvest time and initial water content for assessing the seed quality of four sweet corn genotypes: T13.1.8, SB13.1.3, T8.3.6, and T8.3.2. The experiment employed a factorial Randomized Complete Block Design (RCBD) with two factors. The first factor, harvest time, consisted of five levels (73, 76, 79, 82, and 85 days after planting [DAP]). In contrast, the second factor was the initial water content for seed testing, categorized as harvest water content and 10-12% moisture content. Each treatment was replicated three times, resulting in a total of 30 experimental units. The findings indicated that the sweet corn genotypes T13.1.8 and SB13.1, which were harvested at 76 to 82 hours after sowing (DAP) and had an initial water content of 10 to 12%, represented the optimal treatment combination. These genotypes exhibited germination rate and vigor index variables ranging from 92.7 - 100% and 70.67 - 96.67%. Sweet corn genotypes T8.3.6 and T8.3.2 can be harvested between 79 - 85 DAP with an initial water content of 10-12% to obtain seeds with a germination rate ranging from 86.00 - 98.67% and a vigor index of 58.00 - 86.67%. The study results can be used as a recommendation for seed producers to apply the harvest time and water content according to the genotype used, to ensure that the seeds produced have high viability and vigor.

Abstract

The demand for vegetables, particularly mustard greens, in Riau Province continues to rise alongside the overall increase in vegetable consumption. However, current production levels are insufficient to meet this demand, necessitating imports from neighboring regions such as West Sumatra and North Sumatra. Therefore, there is a pressing need to enhance local production. This study aimed to evaluate the effects of varying concentrations of fermented rice washing water and organic NPK on the growth and yield of mustard greens (Brassica juncea L.). The research employed a Factorial Completely Randomized Design, which included two factors. The first factor was the concentration of fermented rice washing water, with four treatment levels: 25%, 50%, 75%, and 100%. The second factor was the application of organic NPK, also with four treatment levels: no organic NPK, 2.25 g/plant, 4.5 g/plant, and 6.75 g/plant. The parameters observed included the number of leaves, wet weight, economic weight, dry weight, net assimilation rate, and relative growth rate. The results indicated that the combination of fermented rice washing water and organic NPK had a significant effect on all observed parameters except for dry weight, with the optimal treatment being a concentration of 100% and 6.75 g of organic NPK per plant. The application of rice washing water significantly influenced all observed parameters, with the best treatment being fermented rice washing water at a concentration of 100%. Additionally, the effect of organic NPK was significant across all observed parameters, with the optimal treatment being 6.75 g per plant. The combination of fermented rice washing water and organic NPK effectively enhanced the growth and production of mustard greens, resulting in a production yield of 20.2 tons per hectare.

Abstract

The increasing population necessitates a corresponding rise in rice production each year, a condition significantly influenced by cultivation practices and the application of technology. This study aims to evaluate the agronomic characteristics of three superior rice varieties at different planting distances within the System of Rice Intensification (SRI) framework. The research will be conducted in Geulumpang Payong Village, Jeumpa District, Bireuen Regency, at an altitude of approximately 0 to 969 meters above sea level (masl) from August to November 2024. This study employed a split-plot design (RPT) experimental method within a randomized block design (RAK). Two factors were tested: varieties (Ciherang, Inpari 49, and Mustajab) and planting distances (25 cm x 25 cm as the control, 25 cm x 30 cm, 30 cm x 30 cm, and 35 cm x 35 cm). Consequently, 12 treatment combinations were established, with each treatment replicated three times, resulting in a total of 36 experimental units. Each plot contained four research plants, leading to a total of 144 plants. The data obtained from the research were statistically analyzed using the F-test with SAS V9.12 software. If the results of the analysis of variance indicated significant differences at the 5% level, the Duncan Multiple Range Test (DMRT) was conducted. The results suggested that the variety had a considerable influence on the parameters of plant height and the number of leaves. In contrast, leaf area, root length, and the number of tillers did not show significant effects. In terms of planting distance, the number of leaves and tillers was significantly affected, while plant height, leaf area, and root length did not exhibit significant changes. The interaction between the two factors had a substantial impact on the number of leaves, while plant height, leaf area, root length, and the number of tillers showed no significant effects. The Ciherang variety, combined with a planting distance of 30 cm x 30 cm, emerged as the most effective treatment, indicating it was the optimal condition in this study.

Abstract

Glutinous corn (Zea mays ceratina L.) is a distinctive variety known for its unique starch characteristics and high economic value. One of the challenges affecting glutinous corn plants' productivity is the soil's low nutrient content. To address this issue, improving the fertilization system is essential, which can be achieved by balancing the application of chemical fertilizers and organic fertilizers within the cultivation system. This study aims to identify the optimal doses of liquid organic fertilizer and NPK 16-16-16 fertilizer to enhance crop yields and improve fertilization efficiency. The research employed a factorial randomized block design (RAK) with two factors. The first factor is the dose of liquid organic fertilizer (C), which includes the following levels: control (without POC), 2 ml/l, 4 ml/l, and 6 ml/l. The second factor consists of the control (recommended dose of 4.5 g/plant) and doses of 2.25 g/plant, 3 g/plant, and 3.75 g/plant. Reason: Improved clarity, readability, and technical accuracy while maintaining the original meaning. The results indicated an interaction between the combination of liquid organic fertilizer and NPK 16-16-16 fertilizer treatments concerning the sugar content of glutinous corn. The treatment without applying liquid organic fertilizer (0 ml/l) yielded the highest cob weight without husks, measuring 211.22 g. Additionally, the application of NPK 16-16-16 fertilizer resulted in glutinous corn's most significant plant height at both 14 and 42 days after planting (DAP). It contributed positively to the sugar content of the corn.

Abstract

Rice is a widely cultivated and consumed food commodity. In Indonesia, the increasing population growth has led to a rise in both rice consumption and demand. The purpose of this study was to determine the effects of gamma-ray treatment on the properties of Jangguik rice, specifically regarding seed growth duration, seedling height, number of leaves, and seedling weight. The research was conducted in Koto Kari Village, located in the Kuantan Tengah District of Kuantan Senggigi Regency. The Deputy provided gamma irradiation services for Research and Innovation Infrastructure at the Yogyakarta Radiation Laboratory, situated on Jl. Babarsari, Depok, Sleman, Yogyakarta. The research was conducted over two months, from June to July 2024. This experiment employed an experimental method utilizing a Randomized Block Design with one factor. The study consisted of five treatments, each repeated three times, resulting in a total of 15 experimental plots. The treatments tested included doses of 0 Gy, 100 Gy, 200 Gy, 300 Gy, and 400 Gy. The study's results were analyzed statistically using an ANOVA table. If the calculated F-value exceeded the F-value from the table at the 5% significance level, further analysis was conducted using the Honestly Significant Difference (HSD) test at the same significance level. The results of the study indicate that gamma-ray irradiation treatment exerts a multifaceted impact on the growth of Jangguik rice seedlings. The following data were collected for analysis: the parameter of seed growth days (0 Gy treatment: 3.41 days after planting; 300 Gy treatment: 6.06 cm); the number of leaves (200 Gy: 5.46 pieces); and the weight of 100 Gy seedlings (0.146 grams).

Abstract

The study aims to determine the level of atonic concentration and the type of biostimulant that can increase the yield of small chili peppers in the lowlands. The design used was a factorial Randomized Block Design (RBD) consisting of two factors. The first factor is the concentration of atonic (A), namely: A0 = 0.0 ml / l; A1 = 1.5 ml / l, A2 = 2 ml / l; and A3 = 2.5 ml / l. The second factor is the provision of several types of biostimulants (B), namely: B0 = without biostimulant; B1 = Plant Growth Stimulator; B2 = EM4; B3 = Superbionic Fertilizer. Data analysis used analysis of variance and if there was significance, further testing was carried out with the Duncan Multiple Range Test. The results showed that the urea fertilizer package with a dose of 200 kg / ha, SP-36 50 kg / ha, and KCl 50 kg / ha gave better seed yields than the control but was not significantly different from higher doses of N, P, K fertilizers.
