Abstract

Proximate analysis was conducted on cookies with different formulations of mocaf, purple sweet potato flour, and robusta coffee powder. This study aimed to analyze the proximate composition of cookies containing mocaf, purple sweet potato flour, and robusta coffee powder. A completely randomized design with five different treatments was used. The results showed that the moisture content ranged from 5.42% to 6.43%, with A5 (25% mocaf + 50% purple sweet potato flour + 5% robusta coffee powder) having the highest moisture level, exceeding the SNI standard (≤5%). The ash content ranged from 0.96% to 1.47%, meeting the SNI standard (≤1.5%). The highest fat content was found in A5 (35.03%) and A4 (50% mocaf + 50% purple sweet potato flour + 5% robusta coffee powder, 33.44%), which exceeded the SNI standard (≤9%). The highest protein content was also found in A5 (4.42%) but remained below the SNI standard (≥5%). The highest carbohydrate content was found in A1 (60.88%), whereas A5 had the lowest (52.79%). The highest crude fiber content was obtained for A5 (7.32%). The study concluded that increasing the proportion of purple sweet potato flour increased moisture, ash, fat, protein, and crude fiber content but decreased carbohydrate levels. In contrast, a higher proportion of mocaf increased carbohydrate content but reduced crude fiber levels. Keywords: proximate analysis, robusta coffee powder, cookies, mocaf, purple sweet potato flour

Abstract

The Indonesian Sustainable Palm Oil (ISPO) program was established in 2011 in response to the adverse environmental impacts caused by the expansion of palm oil production in Indonesia. To date, the ISPO implementation in Jambi Province is still relatively low. This is because there are many weaknesses and challenges in implementing the ISPO. This study aimed to identify implementation strategies for sustainable palm oil certification in Jambi Province. This analysis uses the A'WOT approach, which integrates the Analytical Hierarchy Process (AHP) and SWOT analysis. Based on the A'WOT analysis, 23 external and internal factors were obtained, which are strengths, weaknesses, opportunities, and threats. In addition, the A’WOT analysis results show that the priority strategy that can be implemented is to involve MBKM (Merdeka Belajar-Kampus Merdeka, Freedom of Learning-Independent Campus) students in helping farmers. This strategy is because independent smallholders' understanding of ISPO is low and the number of ISPO extension workers or assistants is also limited. Therefore, the choice of strategy that can improve understanding of ISPO implementation is to involve MBKM students to help provide counseling and understanding related to ISPO. Keywords: AHP, independent smallholders, ISPO, oil palm, SWOT

Abstract

Continuous use of inorganic fertilizers that do not follow Good Agricultural Practices causes soil damage. Organic fertilizers are complementary fertilizers that can maintain soil moisture and fertility, increase the soil water-holding capacity, and increase the amount of water available to plants. The purpose of this study was to determine the effect of compost prepared from banana peel and rotten tomato (10:3) and different watering intervals on the growth of oil palm seedlings at the pre-nursery stage. The experiment was conducted from February 2022 to August 2022 in Kedokan Agung Village, Kedokan Bunder District, and Indramayu Regency. The experiment used a Randomized Block Design consisting of nine treatments and three replicates, with each treatment consisting of two plants. The combination of treatments used compost with intervals of watering the oil palm seedlings. The results showed that the application of 1 kg/plant compost with daily watering resulted in the best growth and significantly affected plant height, trunk circumference, number of leaves, and leaf area. This treatment produced a growth response that was as good as that of plants given inorganic fertilizers. Keywords: compost, organic fertilizer, prenursery, watering interval

Abstract

The agribusiness of food commodities in the Manding District is dominated by local corn. Over 90% of the farmers in the district regularly cultivate Manding variety corn as an alternative crop, planting it at least once a year. The change in the fertilizer subsidy policy in 2022 caused several problems in the district, including a reduction in the availability of fertilizer for farmers due to purchasing quota limitations. This condition leads to unmet fertilizer needs, prompting farmers to purchase non-subsidized fertilizers to cover the shortfall. Consequently, production costs increase significantly. Another issue is the delay in the distribution of subsidized fertilizer, which can affect crop growth and productivity. This situation can impact the competitiveness of corn commodities. This study aims to analyze the impact of government policies on corn commodities and the competitiveness of local Manding corn, considering comparative and competitive advantages. The study area was selected purposively, and 42 corn farmers were chosen as respondents using purposive sampling. Data analysis was conducted using the Policy Analysis Matrix. Based on the analysis, it was found that the government's fertilizer policy could help save costs. Meanwhile, the pricing policy resulted in farmers receiving lower prices than before. Overall, Manding local corn farming in Manding District maintains both competitive and comparative advantages. This is evidenced by the Private Cost Ratio and the Domestic Resource Cost Ratio, both of which have values less than one. Keywords: competitiveness, corn, government policy, Manding corn

Abstract

Phenols play an important role in inhibiting the decomposition rate of peats. This research compares the total phenols, tannins, and colonies of phenol-degrading bacteria in natural and cultivated peatlands. The work was conducted from September to December 2023 on the peatlands in Pontianak, West Kalimantan. Samples of 60 cm3 were collected from the peat surface. The samples were taken from 4 types of peats, namely natural peats covered by ferns (A), cultivated peat with raised beds (B), cultivated peat with raised beds ameliorated with lime and beef manure (C), and cultivated peat with raised beds ameliorated with lime, beef manure, and Jadam fertilizer (D). The total phenols content was measured using the Folin-Ciocalteu 10% method using a UV-Vis spectrophotometer at a wavelength of 765 nm. The total tannins content was measured using the Folin-Denis method using a UV-Vis spectrophotometer at a wavelength of 740 nm. Total bacterial colonies were counted using the Total Plate Count method on selective Mineral Salt Medium (MSM) agar with the addition of phenol solution. The results showed that the average total phenols and tannins content values were generally low in the cultivated peats, particularly in the raised bed (B). The results indicate that the cultivated peat accelerates the activity of phenol-degrading bacteria. Keywords: Jadam fertilizer, phenols, phenol-degrading bacteria, peats, tannin

Abstract

Dark brown local glutinous sorghum has the potential to replace white rice because it has higher carbohydrate and dietary fiber contents and lower total sugar content. Sorghum has the disadvantages of hard seeds and astringency, which can be reduced by polishing and soaking. The aim of the research was to study the effect of the polishing frequency and soaking condition on sorghum seed with 2 research variables: (1) the polishing frequency [once and twice] and (2) soaking conditions [(1) 100°C water allowed to reach room temperature for 24 h; (2) 100°C water allowed to reach room temperature for 36 h; (3) baker's yeast 0.25% b/v at room temperature for 24 h; and (4) baker's yeast 0.25% b/v at room temperature for 36 h]. Rice quality was tested for hardness, elasticity, chewiness, stickiness, organoleptic properties, and antioxidant activity. Data was processed using ANOVA (α = 0.05) and Duncan’s Multiple Range Test. The results showed that the polishing frequency and soaking conditions affected the hardness, elasticity, chewiness, and stickiness of sorghum rice. The best sample was found to be twice-polished dark brown glutinous sorghum rice, with a 100 °C water soaking condition, and allowed to reach room temperature for 36 h. The sorghum rice had a hardness of 2,578.6 ± 1,044.4 gf, elasticity of 48.24 ± 0.20%, chewiness of 0.3622 ± 0.00, stickiness of (-76.88 ± 0.76) gs, with antioxidant activity of 0.0041 mg/g (strong), which panelists liked and similar with rice from the parameters of color (score 5.0 ± 0.2), aroma (score 4.5 ± 0.1), texture (score 4.8 ± 0.1), and taste (score 4.5 ± 0.1).

Abstract

Controlling pests and diseases of chili plants still relies on synthetic chemical pesticides, which have negative effects on agroecosystems. Biopesticides can be used as alternatives to synthetic pesticides. The use of biopesticides in Indonesia is still low, and popularization efforts are required. The government plays a role in determining policies that encourage the popularization of biopesticides. This study aimed to determine policy priorities for the popularization of biopesticides for chili farmers. Policy priorities are determined using the analytical hierarchy process (AHP) method, which allows the identification of priority criteria and priority sub-criteria. The current policy on crop protection is insufficient to encourage the popularization of biopesticides. Low commercialization and government programs that are not yet massive are indications of the low use of biopesticides. The AHP results showed that the criteria for knowledge about biopesticides are policies that must be prioritized, where the sub-criteria of the level of intensity and quality of extension are the top priorities. The effectiveness and efficiency policy criteria need to prioritize the effectiveness of sub-criteria in controlling pests and diseases over the efficiency of use, preservation of natural enemies, and product quality, while the ease of obtaining products is the main factor in prioritizing the availability and affordability criteria. Keywords: analytical hierarchy process, AHP, biopesticide, farmers, IPM, policy

Abstract

Waste management is still a significant challenge in Indonesia; organic waste is the most abundant type of waste on a national scale. A potential solution to this problem is to utilize black soldier fly (BSF) larvae as a bioconversion agent for organic waste. The purpose of this study is to determine how much organic waste is absorbed by BSF maggots, to determine the financial feasibility of BSF maggots as local chicken feed, and to analyze the efficiency value of BSF maggot cultivation in a circular economic system. The study utilized four distinct growing media: P0 = 100% kitchen organic waste (KOW); P1 = 100% cow dung; P2 = 50% KOW, 50% cow dung; and P3 = 50% KOW, 50% dairy waste. The analysis used in this study is descriptive-quantitative, and economic analysis is carried out by comparing the processes of drying, grinding, and mixing local chicken feed. The total amount of decomposable organic waste is 237 kg. Media grows P3, which is the most profitable for BSF maggot cultivation. Maggot meal production is worth developing based on the payback period and R/C. P1 can help the composting process, and production costs are efficient. The processing of maggot flour into local chicken feed is a lucrative venture, as evidenced by the potential profits it generates. This research underscores the significance of implementing a circular economy with BSF maggots in decomposing organic waste and its utilization as an ingredient in chicken feed. Keywords: BSF larvae, circular economy, organic waste

Abstract

Alphitobius diaperinus is an insect pest that is difficult to control in conventional chicken farms. In high populations, this insect can damage the infrastructure of the coop, disrupt chicken feeding activities, and is a known vector of pathogens. Currently, the control of A. diaperinus still relies on synthetic insecticides that have been proven to be resistant to target pests, toxic to non-target organisms, and pollute the environment. This study aimed to analyze the potential of gamal (Gliricidia sepium) leaf extract as a bioinsecticide in terms of repellency response and its effect on the metamorphosis of A. diaperinus. The repellency response was measured through a preference test using a Y-olfactometer at 6 concentration levels, whereas metamorphosis ability was tested at 6 sub-lethal concentrations. Each treatment was performed in 5 replications. The repellency response was descriptively analyzed based on the repellency percentage (PP) and preference index (IP) values. The metamorphosis ability test results were analyzed using non-parametric Kruskal-Wallis and Mann-Whitney U tests. The results showed that all treatments had PP values > 80% with negative IP. The results of the Kruskal-Wallis test showed significant differences in the extract concentrations between the treatment groups (asymp. sig < 0.05). A higher extract concentration caused a decrease in the number of larvae that successfully became imagoes. In conclusion, A. diaperinus showed a high repellency response to gamal leaf extract, and the gamal leaf extract had a strong repellent effect. The extract concentration also affected the metamorphosis of A. diaperinus larvae. Keywords: Alphitobius diaperinus, bioinsecticide, Gliricidia sepium, Metamorphosis, Repellency response

Abstract

This study examined the effects of an aqueous extract of Muntingia calabura L. leaves on the inhibition of germination and growth of Amaranthus spinosus. The study used a single-factor Completely Randomized Design, namely, the concentration of extract with treatment levels of 0, 2, 4, and 6% for germination and 0, 10, 20, and 30% for growth. Data were analyzed using Analysis of Variance and Duncan's Multiple Range Test at a confidence level of 95%. The results showed that treatment with the aqueous of leaf extracts decreased the percentage of germination, germination index, radicle, and stem length of the sprouts and slowed the germination time. During growth, it decreased the plant height, number of leaves, fresh weight, dry weight, and extended flowering time. The higher the concentration of the extract, the greater the decrease in the germination and growth of the weed. At concentrations of 10 and 20%, the contents of chlorophyll a, chlorophyll b, and carotenoids increased, but at a concentration of 30%, the contents began to decrease. At a concentration of 6%, germination decreased by 75%, germination index decreased by 87.47%, sprout length decreased by 27.51%, radicle length decreased by 26.20%, and germination time increased by 14.74%. At a concentration of 30%, the plant height was 6.48%, the number of leaves was 38.13%, the fresh weight was 20.64%, and the dry weight was 18.36%; however, the flowering time increased by 40%.
