Abstract

Every year, up to 1.3 trillion tons of global food produced for human use are lost or wasted. Consumer behavior is a major cause of food waste. In Indonesia, households generate approximately 38% of total food waste. The goal of this study is to evaluate at how attitudes toward behavior, subjective norms, perceived behavioral control, and intention to reduce food waste affect food waste behavior in households. The theory of planned behavior (TPB) was used to conduct the survey, which included 160 independent oil palm farmer homes. The collected data was then examined using Structural Equation Modelling (SEM) with the AMOS 24 program. The findings demonstrate the effectiveness of the TPB model in forecasting household food waste behavior. Attitude, subjective norm, perceived behavioral control, and goal to reduce food waste are the factors that influence household food waste behaviors. The study's findings show that perceived behavioral control is the most important predictor of food waste behavior. Furthermore, the findings demonstrate that attitudes and subjective norms can predict the intention to reduce household food waste. Meanwhile, the desire to eliminate food waste appears to be a strong predictor of one's attitude on the amount of food waste produced. Keywords: food waste, household behavior, SEM-AMOS, theory of planned behavior

Abstract

Fusarium oxysporum is a cosmopolitan fungal species that can cause wilt disease in various plants. This study aimed to determine the antifungal activity of Gliocladium viride against F. oxysporum and identify the antifungal compound produced by G. viride. An antagonistic test of G. viride against F. oxysporum was carried out in dual culture. The antifungal activity of G. viride extract on the growth of F. oxysporum was determined using the paper disc diffusion method. The results showed that G. viride inhibited the growth of F. oxysporum colonies, with inhibition percentages ranging from 92.93% to 93.92%. The extract has antifungal activity, with the diameter of the inhibition zone formed being categorized as strong inhibition, which ranges from 19.3 mm to 24.5 mm. G. viride extract contains eleven compounds that have antifungal activity, namely cyclopropanecarboxylic acid; 2-nonanone; 2,3-butanediol; 2-heptanone; acetoin; 2,3-dimethylpyrazine; carbamic acid, phenyl esters; pyridine, 2,3,4,5-tetrahydro; 2-furancarboxaldehyde, 5-methyl; caryophyllene; and 1,2, benzenedicarboxylic acid. The results of this study provide information that G. viride can be used as a biological agent to control wilt in banana, vanilla, tomato and chili plants. Keywords: Gliocladium viride, antifungal activity, Fusarium oxysporum

Abstract

Conventional orchid cultivation is thought to be ineffective and time-consuming. Simple tissue culture procedures are insufficient to increase orchid quality. The need for ongoing development can be met by integrating different plant breeding strategies in orchid tissue culture, such as induction mutation, elicitor addition, and genetic transformation. The purpose of this article was to report on current improvements in the use of plant breeding techniques to orchid tissue culture to increase orchid quality. This article referenced significant scientific publications. Orchid tissue culture using mutation induction is used to develop improved variations. Giving elicitors can cause orchid plants to conserve themselves and become more resistant to diseases. The required transgene can be introduced into the genome of cultivated orchids via Agrobacterium. These advancements have the potential to revolutionize orchid cultivation. Keywords: biotechnology, orchid, tissue culture

Abstract

Shallots are one of the horticultural commodities that have fluctuating prices. Market integration occurs horizontally but not vertically due to poor information systems at the producer and consumer levels. This study aimed to estimate the area of shallot land quickly using the rapid classification of croplands method. The research was conducted in Merek District, Karo Regency, North Sumatra. Primary data obtained from survey activities were processed using the Google Earth Engine platform. Classification and regression trees (CART) and random forest (RF) algorithms were used to classify land cover as onion and non-onion classes. The shallot land area based on this method was 74.4 hectares, with an area accuracy of 95% (RF) and 24% (CART) and a location accuracy of 92% (CART and RF). The rapid classification of croplands method can estimate land area quickly. It helps stakeholders who need information on shallot production projections and can be developed to improve the vertical market integration information system (market integration between producers and consumers). Some areas for improvement of this method are limited access and resolution, inability to describe up to the level of garden bunds, and the condition of the area covered by clouds, which will affect the accuracy of the results. Keywords: shallots, production estimation, google earth engine, remote sensing

Abstract

The sugar palm is one of the most important commodities in the Rejang Lebong Regency. Sugar palms have not been widely processed into value-added products because the community solely produces brown sugar. The goal of this study is to identify potential challenges and propose product diversification strategies that will boost the value added and sustainability of sugar palm firms in the Rejang Lebong Regency. This study was carried out in the Rejang Lebong Regency during August to October 2023. Data were gathered through observations, focus group discussions, and in-depth interviews. A fishbone diagram was used to identify potential and map product diversification challenges, while palm product diversification plans were developed using a strengths, weaknesses, opportunities, and threats (SWOT) matrix. The research results indicated that the diversification of sugar palm products is hindered by limited human resources in using technological innovations, restricted use of agricultural machinery, insufficient business partnerships, and local government programs that are not yet integrated into the development of product diversification. The strategy for sugar palm product diversification can be implemented by developing market alliances and improving processing technologies for MSMEs, with government program assistance and access to funding. This technique is expected to improve the quality and pricing of sugar palm products at the farmer level. Keywords: added value, aren palm, Arenga pinnata Merr, diversification strategy

Abstract

Telindale Beach is part of the Central Rote Sub-district in the Rote Ndao Regency. The beach is also a seaside region with many community activities, including tourism, recreation, and sales. These activities have a significant impact on the health of aquatic ecosystems. The presence of pollutants in water might cause a decline in its quality. Gastropods are among the species that are sensitive to changes in water quality. This study sought to provide information on gastropod diversity as a bioindicator of water quality at Telindale Beach. This study was both descriptive and quantitative, with the location determined through purposive sampling. The line-transect approach was applied at three locations, each with a different substrate. The data were evaluated using diversity, uniformity, and dominance index techniques. The research revealed that the gastropods identified at the beach belonged to 13 families, 15 genera, and 19 species, with 112 individuals across all stations. The diversity index ranged from 0.27 to 2.33 (moderately contaminated), the uniformity index was 0.84-0.91 (high), and the dominance index was 0.12-0.31 (moderate). According to the species diversity index data, the waters near Telindale Beach were the most polluted. Keywords: bioindicator, gastropods, Telindale Beach

Abstract

Lamb is important in providing balanced and healthy nutrition as a source of protein, fat, and essential micronutrients such as iron, zinc, and vitamin B complex. The mineral and vitamin content of meat from local breeds needs to be evaluated as a portrait of the genetic quality data of sheep and as a reference for developing sheep that produce healthy and high-quality meat. This study aimed to analyze the mineral and vitamin B contents of Sapudi sheep and Merino cross sheep meat from the longissimus dorsi area to invent genetic quality data for the meat of these two sheep. Three Sapudi and three Merino cross sheep were kept under similar conditions for two months. Meat collection from the longissimus dorsi muscle was carried out to analyze vitamin B and mineral content. A t-test was then performed to determine meat quality. The results showed that the mineral content of Mn and Cu in Sapudi sheep meat was lower than that in Merino cross meat. The vitamin B2 content in Sapudi sheep (0.11 mg/100 g) is lower than that of Merino cross (0.20 mg/100 g). In comparison, the vitamin B3 content of Sapudi sheep meat was higher (0.51 mg/100 g) than Cross-merino (0.40 mg/100 g). This research concludes that breeding influences nutrient content, and Merino crossbreed sheep are superior to Sapudi sheep in terms of vitamin B and mineral content. Keywords: genetic resource, Indonesian local lamb, meat quality, mineral, vitamin

Abstract

The availability of water plays an important role in plant growth. However, water availability depends on the climate and irrigation channels; therefore, there is little water available for plants during the dry season. Bacteria found in soil can produce exopolysaccharides to survive under extreme land conditions, namely, during drought conditions. The research objectives were to (1) isolate and select bacteria originating from dry land for use on chili plants and (2) determine the effect of water supply frequency and select soil bacteria on chili plants. The experiment consisted of two stages. (1) Bacterial selection and characteristics, which included exopolysaccharide bacteria selection on specific ATCC No. media. 14; pathogenicity test (hypersensitivity and hemolysis); characterization and biochemical testing including pH, temperature, salinity, oxidation, and catalase; bacterial functional tests (P and K solvents and nitrogen-fixing); and (2) tests of chili plants in the greenhouse. The treatment consisted of two factors: (a) application of selected bacteria, (b) frequency of water application (every 1, 2, 3, and 5 days), and (3) molecular identification of selected bacteria. The results showed that the best growth of chili plants was obtained by treating them with bacteria and watering them every other day. Molecular identification demonstrated that the selected bacteria was Sphingomonas yunannensis, which can grow under environmental conditions affected by drought. Keywords: exopolysaccharides, drought, Sphingomonas yunannensis, chili plants

Abstract

IPB D1 chicken is a local chicken resulting from crossing pelung, sentul, kampung, and parent stock broiler strain Cobb chickens. IPB D1 chicken was released through a decree by the Ministry of Agriculture with No. 693/KPTS/PK. 230.M/9/2019. Free-range is a system of raising farm animals, including chickens, by providing access to outdoor running (pasture) to exercise, find more feed, and be exposed to more oxygen. This study analyzed the carcass percentage, edible carcass, non-edible carcass, and chemical quality of IPB D1 chickens raised in a free-range system. A total of 50 IPB D1 male chickens were raised in free-range and intensive systems for four weeks. The microclimatic data were analyzed descriptively. Meanwhile, carcass percentage and physicochemical and organoleptic properties of IPB D1 chicken meat were subjected to a t-test. Free-range and intensive systems showed no significant effects on the carcass, commercial cuts, edible and non-edible percentages, and MDA quality traits of IPB D1 male chicken thigh meat. The cholesterol content of IPB D1 thigh meat in a free-range system was significantly lower than in an intensive system Keywords: carcass, free-range, IPB D1 chicken, cholesterol, MDA
