Abstract

One factor affecting sweet corn's (Zea mays saccharata Sturt.) productivity refers to soil fertility and proper fertilization. This study aimed to determine the optimal combination of NK and P fertilizer doses to enhance the growth and yield of corn grown on Inceptisols. This research was conducted at the Soil Chemistry and Plant Nutrition Experimental Field, Faculty of Agriculture, Universitas Padjadjaran. The Randomized Block Design consisted of 10 treatments with three replicates each. The treatments included: A, control; B, standard NPK; C, ¼ dose NK + 1 P + ½ N; D, ½ dose NK + 1 P + ½ N; E, ¾ dose NK + 1 P + ½ N; F, 1 dose NK + 1 P + ½ N; G, 1¼ dose NK + 1 P; H, 1 dose NK; I, ½ dose NK + ½ single N,P,K; and J, ¾ dose NK + ¼ single N,P,K. The results showed that the combination of NK and P fertilizers significantly affected the growth and yield of sweet corn. The treatment with ¾ NK + 1 P + ½ N had a notable impact on cob weight (0.33 kg/cob), cob diameter (5.05 cm), and cob length (21.2 cm). This treatment also increased K absorption to 34.49, available soil K to 2.45 cmol kg-1, and the sweetness level of corn to 13.56%. This study provides new recommendations for corn fertilization to improve the growth and yield on Inceptisols. Keywords: optimal fertilizer dosage, corn growth, corn productivity, nutrient uptake

Abstract

Guava crystal is a fruit that has a high selling value. One of the obstacles to marketing crystal guava fruit is the fast decay process. Many factors cause fruit to rot quickly, including microbial contamination post-harvesting. This study evaluates the effectiveness of adding lemongrass oil in chitosan coatings to protect crystal guava from microbiological damage during storage. The fruit is coated with 1% chitosan and added to lemongrass oil according to the treatment. The study used a completely randomized design with three replications. The treatment tested included 0.0, 0.1, 0.3, and 0.5% lemongrass oil. The content of lemongrass oil compounds was analyzed using gas chromatography-mass spectroscopy (GC-MS). The antibacterial test was carried out using the disc method. The parameters observed were the total plate count and total fungal count of crystal guava fruit on days 0, 3, 6, 9, 12, 15, and 18 after storage. GC-MS analysis showed that the main content of lemongrass oil is two isomers of citral, i.e., neral (38.54%) and geranial (39.26%). The results showed that the total fungal and plate count increased during storage. Chitosan coating with lemongrass oil more effectively inhibits Staphylococcus aureus than Escherichia coli. Adding 0.3% and 0.5% lemongrass oil in chitosan could restrain the rate of microbes in crystal guava until the 18th day after storage. Chitosan treatment with 0,3% lemongrass oil is recommended to be the best treatment for applying on crystal guava. Keywords: citral, GC-MS, Psidium guajava L., total plate count, total fungal count

Abstract

Indonesia ranks second in the world for high food loss and waste levels, totaling 300 kg per capita per year. Most of these losses occur during harvesting and post-harvest stages before the produce reaches the consumer. This research aimed to determine the correlation between these stages and production loss. The research was conducted using a descriptive quantitative method in Sungai Besar Village, Ketapang Regency, from November 2022 to February 2023. The respondents in this study were 89 farmers in the village. The results showed that each stage, including the harvesting and post-harvest stages, was correlated to yield loss. The yield loss at each stage varied greatly and is affected by several factors, including harvest age, harvesting methods, tools, rice varieties, threshing mechanisms, threshing delays, drying duration, drying medium size, grain cleaning, raw grain materials, maturity level, and milling machines. The percentage of yield loss ranges from 2 to 4.46% (in the harvesting and threshing stages), 0.52 to 1.55% (in the drying stage), and 1 to 2,5% (in the milling stage). Keywords: rice, food loss, harvester, post-harvest

Abstract

Sentul Rain Forest Tourism (SRFT) is one of the ecotourism objects developed in a forest area managed by Perhutani Public Company in collaboration with a private company. This study examined the social, economic, and environmental impacts of SRFT on the surrounding community before and after SRFT development. The study used quantitative descriptive analysis methods, with interviews and questionnaires. Respondents were divided into two groups: community groups receiving direct and indirect impacts. The results showed that SRFT had a positive social impact, namely increasing social accessibility, which can increase people's mobility. Economically, SRFT created jobs and increased people's income in community groups with direct and indirect impacts. Environmentally, it increased the tree covering and positively changed people's attitudes towards forest management. However, the development of SRFT also has a negative impact. Socially, increasing conflict between tourists and the community, both in the community groups receiving direct and indirect impacts. Economically, it increased the externality costs to community groups that receive direct impacts. Keywords: economy impact, ecotourism, environmental impact, rain forest, social impact

Abstract

The peel of dragon fruit is a waste. The meat of dragon fruit is the most frequently consumed; the peel is rarely used and is only wasted. The natural antioxidant lycopene may be found in the skin of dragon fruit. Dragon fruit skin can be processed to make herbal tea. This study aims to ascertain the yield, moisture content, and organoleptic testing to produce dragon fruit peel tea and the effects of adding cinnamon, ginger, and lemon zest. The research treatments included lemon zest at 40%, ginger at 14%, and cinnamon at 6% concentrations. Three treatment levels and three replications were employed in the fully randomized design (CRD) for data analysis. According to the study's findings, the best way to treat a dragon fruit peel herbal tea bag that contains 6% cinnamon powder was to know how adding cinnamon, ginger, and lemon zest to the process of making dragon fruit peel tea affects the yield, moisture content, and organoleptic test. According to the respondents' liking, the taste test scored 3.91%, scent 3.88%, and color 4.45% (loved) (liked). Based on SNI 3836.2013 about tea quality criteria, which stipulates that the maximum moisture content included in tea powder is 8%, a yield of 8.64%, and a moisture content of 0.48% satisfy the tea quality requirements. Keywords: dragon fruit peel, cinnamon, ginger, lemon zest, red dragon fruit peel tea

Abstract

Farmer groups play an important role in the palm oil industry in terms of access to capital, production facilities, marketing, market information, and learning vehicles. However, the participation of independent smallholders in institutions, especially farmer groups, is still very limited because of the limited knowledge and awareness of farmers about the important role of these institutions. The aim of this research is to formulate an increase in the participation of independent oil palm smallholders in farmer groups in the Sambas Regency, West Kalimantan. The research used a combination of qualitative and quantitative methods with a SWOT-AHP analysis of 33 experts and ordinary informants from the government, farmer group officials, companies, wholesalers, and farmers. The results show that institutional capacity building was selected as a strategic priority for increasing farmer participation. Three efforts must be made to increase institutional capacity: compiling institutional norms/rules, holding regular meetings, and compiling group administration books. Keywords: farmer group institution, participation, oil palm smallholder

Abstract

Independent oil palm farmers are crucial to the growth of the national economy. However, due to subpar institutional and farmer group performance, independent oil palm farmers' productivity still needs to improve. This research aimed to maximize institutional performance within the frameworks of social exchange theory and resource-based view theory. The study employed structural equation modeling, or SMART-PLS, and quantitative descriptive methodologies to examine 92 farmer group administrators in Sambas Regency, West Kalimantan. The study's findings illustrate that strategic orientation, culture, and commitment affect institutional/farmer group performance. In maximizing institutional performance, the following was done: 1) planning for environmental conservation by setting clear deadlines and assigning members to consider environmental sustainability and refrain from burning land; 2) communicating with the community and members to foster community harmony; 3) holding online group discussions for members who are unable to attend in order to save time discussing issues collectively; b. imposing strict sanctions for infractions by its members; 4) fostering active dialogues among members and working directly or virtually with instructors regarding oil palm cultivation knowledge. The most recent study aims to develop strategies for enhancing institutional and farmer group performance through strategic orientation, culture, and commitment. Keywords: farmer group, performance, independent oil palm farmers, SMART-PLS

Abstract

The demand for food continues to increase as population growth concerns the Indonesian government, as stated in the second goal of the Sustainable Development Goals, namely zero hunger. The National Food Agency (BPN) uses the Food Security Index (IKP) to monitor food security conditions in Indonesia's district/city and provincial levels. Based on the BPN data, most districts/cities in The Land of Papua (so called Irian Province before the year 2000) are food insecure. However, the IKP has a weakness in the subjectivity of determining weights so that it can disguise the failure of a program or exaggerate a success. The model-based clustering (MBC) method can measure the food security of districts/cities in this area based on food security indicators. However, the data conditions are generally not multivariate distributed, and there are many outliers, so this study used MBC with multivariate t distribution because it is more robust. The best model was obtained with two clusters based on the largest Bayesian Information Criterion value. Cluster 1, located in the mountains and islands such as Nduga, Intan Jaya, Mamberamo Tengah, Puncak, and Lanny Jaya, had low food security, low indicator achievements with high poverty characteristics, many households with a portion of household expenditure on the food of more than 65%, low access to electricity and clean water, low life expectancy and average years of schooling for women, and the percentage of stunted toddlers. Meanwhile, Cluster 2, areas with high food security, had the opposite condition. Keywords: food security, model-based clustering, multivariate t distribution, Land of Papua

Abstract

This study aimed to select a proteolytic LAB with probiotic properties that can be applied to manufacture protein hydrolysate from fish heads. Tests on 20 isolates of LAB showed that nine isolates were proteolytic and non-pathogenic. A total of 5 isolates could grow well at 0.5% bile salt stress, and 3 of them could grow at pH 3. These three isolates had antagonistic ability against Salmonella bacteria, and one isolate was sensitive to the antibiotic tested. Molecular identification of the selected LAB isolates showed a 100% sequence similarity with Pediococcus pentosaceus with accession number MT515895.1. The LAB isolate has high proteolytic activity since it can increase the soluble fraction of fish meal powder from 32.10% to 88.38% in 48 hr. Production of protein hydrolysate using tuna waste was carried out for 30 days. Tuna waste protein hydrolysate had a medium antioxidant activity of 25.57 ± 0.93%. The hydrolyzed protein comprised 17 amino acids, including nine non-essential and eight essential amino acids, and is dominated by glutamic acid. Selected LAB isolate is potentially used in protein hydrolysate production, especially for flavor enhancers. Keywords: antagonistic, amino acid, Pediococcus pentosaceus
