Published: November 2024

Indonesia’s strategic food refers to a group of food products that are important in meeting national food needs. This strategic food is the focus of government attention because of its significant impact on food security, the economy, and social stability. The research aims to analyze urban household preferences for strategic food, analyze estimates of urban household demand for strategic food, and analyze the impact of price changes and urban household expenditure on strategic food demand. The research uses Susenas data for 2023, specifically for urban households. Strategic Foods are grouped into rice, corn, soybeans, shallot, chilies, poultry meat, poultry eggs, ruminant meat, consumer sugar, and fish. Analysis of household preference data was carried out using expenditure shares. Demand estimates were analyzed using the LA/AIDS model with the SUR approach. The results of the analysis show that the highest share of urban household expenditure is for rice. Beef is still a luxury commodity with elastic price elasticity. Poultry meat, poultry eggs, and ruminant meat are commodities that are substitutes for each other.

Published: November 2024

The aim of this research is to obtain a method to accelerate vegetative growth through the provision of nutrient solutions using a planting media immersion system (tach system). This research was conducted in the Greenhouse from July to October 2023. This research uses a factorial Randomized Block Design (RBD). The first factor is the frequency of immersion (F) with 3 levels, and the second factor of chicken manure concentrate (C) consists of 2 concentrations. The results showed that the treatment of soaking frequency and nutrient concentration had a significant interaction effect. The results of the regression test showed a linear interaction pattern for all growth variables, except leaf area. The more often you soak the planting medium, the better the growth of the Phalaenopsis amabilis. This shows that plant media soaked in nutrient solution cannot absorb dissolved nutrients for a long time. Based on these results, it was concluded that the more frequent immersion of the planting medium in nutrient solution had a positive effect on the growth of orchid plants. However, this research also shows that although statistically the effect of different treatments is significant on the growth variable, it is not visually obvious.

Published: November 2024

Chili productivity is still relatively low (t ha-1). One of the causes of chili crop failure is pest attacks, as well as extreme environmental changes. On the other hand, in the chili planting environment, a robust ecosystem of various weeds often grows that is not shaken by extreme environmental changes. These weeds contain various elicitors that act as biostimulants to help increase plant productivity and provide defense mechanisms against various stresses. The research aims to increase the resistance of chili plants to major pest attacks and yield by applying elicitor compounds in several indigenous weeds and evaluating the stability of the chili microclimate. The research used a randomized block design with elicitor treatments of Alternanthera sessilis leaves, Cleome rutidosperma, Bidens pilosa, Tithonia diversifolia, a combination of these four leaves, and control (Water). The research results show that applying elicitors for various weeds can increase red chili yields and resistance to significant pest attacks, as well as the stability of the microenvironment of chili plantings. Chili production under condition six harvesting with the application of the Cleome rutidosperma elicitor was 3.8 times greater than the control treatment or an increase in yield of 280%.

Published: November 2024

Farmers typically resort to using seeds obtained from their previous harvests, as the high price of tuber seeds makes them inaccessible. To address this challenge, cultivating quality potato cuttings can be a viable solution. This research aims to evaluate the effect of different concentrations of liquid organic fertilizer on the growth and yield of Granola Kembang potato G0 seed tubers. This study was conducted in Pujon Kidul Village, Malang. The research was carried out from February to June 2023 and involved two stages. In the first stage, four treatments were tested: a control (A0) without the application of LOF, and three treatments with LOF for vegetative phase at concentrations of 1 ml/L (A1), 2 ml/L (A2), and 3 ml/L (A3), each with a dose of 13.88 ml/plant. The second stage involved similar treatments but with LOF for the generative phase. The experiment used a non-factorial completely randomized design (CRD) with four treatments and six replications, resulting in 144 plant samples. The results showed that the application of LOF, particularly at a concentration of 3 ml/L, significantly positively impacted various parameters, such as shoot number, diameter, tuber number, weight, and grading.

Authors: Waskitho Nugroho Tri , Arif Cahyo Wibowo Febri
Published: November 2024

Watersheds are complex natural-human systems because they involve various interacting biogeophysical and socio-economic-cultural components. Degradation of forest, land, and water resources and population pressure have caused a decline in watershed sustainability, which is the biggest obstacle to sustainable watershed management in most developing countries in the humid tropics. The purpose of this study was to analyze the sustainability of the Brantas Watershed. Secondary data collection includes water quality. Data collection was carried out at Perum Jasa Tirta 1. Data analysis was carried out based on a sustainability index that included aspects of water quality. The study showed that the water quality of the Brantas River has decreased and is currently at class 4 (lowest) quality. The sustainability of the Brantas River Basin has decreased and, in 2023, will be in the low category.
Potential of indigenous entomopathogenic fungi diversity in the maize rhizosphere
Authors: Septia Erfan Dani , Sukorini Henik
Published: November 2024

Modern agriculture faces significant overreliance on chemical pesticides, leading to environmental pollution and pest resistance. As a promising alternative, entomopathogenic fungi (EPF) offer a biological approach to pest control. This study investigates the hypovirulence and virulence effects of EPF on corn and cucumber plants by measuring their Disease Severity Index (DSI). The treatment involves isolating and applying fungi to seeds to observe their pathogenic impact. The DSI, which measures disease intensity, is used to determine whether the fungi are virulent (DSI ≥ 2) or hypovirulent (DSI < 2). The virulence treatment involves exposing seedlings to fungal isolates and monitoring symptoms, such as brown hypocotyls, withered leaves, or seed death. Isolates like J5S1U2, J3S1U2, J2S2U1, and J2SU4 were found to be virulent towards cucumber, causing abnormal germination and severe stress. In contrast, hypovirulent isolates, such as J4S2U2, J3S2U1, and T5U1O, caused mild symptoms, including light brown patches under 0.5 cm on hypocotyls without significant wilting, making them safer for agricultural use. The treatment approach emphasizes selecting fungal isolates based on crop-specific virulence, aiming to optimize pest control strategies. Hypovirulent isolates, in particular, are identified as suitable candidates for integrated pest management, as they minimize plant stress while offering effective biological control.

Published: November 2024

The PRL gene in chickens is one gene that plays a role in hatchability and egg production. Therefore, knowing the variation of the PRL gene can be used to predict the performance of egg productivity of native chickens. This study observed the genetics of Indonesian native chickens, White and Wareng chickens and their crossbred based on the Prolactin (PRL) gene in exon 4. Chicken samples were kept at the Experimental Farm, Faculty of Agriculture and Animal Science, University of Muhammadiyah Malang (UMM), Indonesia. DNA isolation and PCR reactions were carried out at the UMM Biotechnology Development Laboratory. Meanwhile, PRL gene exon four sequencing was carried out at the Macrogen Asia Pacific Pte. Ltd Laboratory, Singapore. Gene sequence analysis showed that local Indonesian Putih and Wareng chickens and their crosses were closely related to Gallus gallus and Gallus gallus strain White Leghorn based on the phylogenetic tree with a bootstrap value of 91%. The average genetic distance between native chicken samples was 0.036 and the Tajima test was not significant (p> 0.01) with a value of -1.35379. For further research, it is necessary to research the correlation between gene variation and egg production performance in Indonesian native chickens and their crossbreeds.

Published: November 2024

Vibriosis, caused by various Vibrio species, poses a significant challenge in the aquaculture of Litopenaeus vannamei. Bacteriophages present a promising biocontrol option due to their ability to specifically target and kill bacteria without harmful side effects. This study evaluates the effectiveness of bacteriophages isolated from shrimp intestines and mangrove sediment in controlling Vibrio infections in L. vannamei. Using a Completely Randomized Design (CRD) with five treatment groups and four replications, including control, pathogen-exposed, and various phage treatments, the research found that purified bacteriophages, especially those from shrimp intestines (26 × 109 PFU/mL), significantly inhibited bacterial growth in vitro. In vivo, phage-treated shrimp showed improved immune responses and higher survival rates than controls. Although total hemocyte counts remained unchanged, increased phagocytic activity suggests that phage therapy could be an effective and sustainable method for managing Vibrio infections in shrimp farming.

Published: November 2024

The rising prevalence of gluten-related disorders has increased the demand for gluten-free products. Traditional noodles, primarily made from wheat flour, are unsuitable for individuals with gluten intolerance, necessitating alternative formulations. This study aims to develop glutenfree noodles using composite flours: Mocaf, arrowroot starch, cornstarch, and fish meal, and to evaluate their physicochemical and sensory properties. The research utilized a Completely Randomized Design (CRD) with seven different formulations, varying in the proportions of these ingredients. The noodles were analyzed for moisture, ash, protein, fat, and carbohydrate content using standard methods. Sensory evaluation was conducted by a panel of 30 trained assessors using a hedonic scale. The results indicated that the proportions of Mocaf, arrowroot starch, cornstarch, and fish meal significantly affected the noodles’ moisture, ash, fat content, and sensory attributes like flavor, color, and overall preference. The most preferred formulation was the control (F0), consisting of 100% wheat flour, due to its familiar taste and appearance. In contrast, formulations with higher fish meal content were lfess favored due to a strong fishy odor and darker color. In conclusion, while the addition of fish meal enhances the nutritional profile, it negatively impacts the sensory qualities of gluten-free noodles.

Pepper (Piper nigrum L.) is a high-value cash crop and plays a significant role in Indonesia's agricultural sector. However, pepper production is often hindered by diseases that affect the plant's leaves. This study aims to develop a pepper leaf disease detection model based on image analysis using a Radial Basis Function Neural Network (RBFNN). Conventional methods relying on expert visual assessment are often inefficient, especially on a large scale. In this research, image preprocessing was performed by transforming the images into the CIELAB color space and using K-Means Clustering for feature extraction. Texture feature extraction using the Gray Level Co-occurrence Matrix (GLCM) provides rich information about patterns and intensity distribution in the images, which is effective for distinguishing disease classes. The RBFNN algorithm is then used to identify diseases by capturing the complex non-linearities in the data. Based on the testing results, this model achieved an accuracy rate of 91.67%, demonstrating excellent performance.

Published: November 2024

The growth of the population and vehicles around the campus of Universitas Negeri Semarang (UNNES) has created new challenges related to traffic congestion and air quality. High traffic density can produce exhaust emissions, especially carbon monoxide (CO). CO is a toxic gas that comes from burning fossil fuels, such as those produced by motor vehicles. Long- term exposure to CO can cause serious health problems, including respiratory problems, cardiovascular disease, and even death. To address these issues, a real-time CO concentration monitoring system is required. However, the current CO concentration monitoring system has limitations in terms of accuracy and precision. The Fuzzy Logic (FL) method offers several advantages, including high accuracy and ease of comprehension. To implement this, research stages are necessary, including tool coding and data analysis using FL. The results of the research indicate that CO levels in each UNNES Faculty are approximately 3-20 ppm, with CO levels stabilising at 6 ppm. Therefore, the CO monitoring system using FL was successfully implemented.

Published: November 2024

A digital survey is a technique for gathering information and client feedback on the goods or services they have received. In this situation, digital surveys can be utilized to gauge how satisfied PDAM (Regional Water Supply Company) customers are with the support they received from the mWater application. This digital survey might include questions about PDAM services, such as response time, water quality, and amenities offered. Customers can respond by leaving comments or rating items on a scale. There are still a lot of filling errors in surveys since conventional methods, which still employ paper media to collect respondent data, are still used to conduct surveys. Overall, conducting a customer satisfaction survey using the Slovin formula and the mWater app is a successful and efficient way. The Slovin formula is used to calculate the necessary sample size from the customer population, and the mWater application, which is based on a geographic information system (GIS), enables PDAMs to construct survey forms and collect survey replies quickly and efficiently. The results of this survey can then be applied to raise customer service standards.

Published: November 2024

Bullying is a major problem in schools, involving aggressive and intentional behavior against others. This study aimed to investigate the effectiveness of animated media in enhancing empathy among high school students as a preventive measure against bullying. The research was conducted at State Senior High School 2 Bangkalan–Madura, using a pretest-posttest control group design. Students with low empathy levels were chosen through purposive sampling. The empathy of these students was measured using The Perth Empathy Scale (PES) and the Interpersonal Reactivity Index (IRI). The study divided students into two groups: experimental group watched three animated videos about different types of bullying (physical, verbal, and relational), while the control group did not receive any intervention. The effectiveness of the animated videos was evaluated by comparing empathy levels before and after the intervention. The results showed that the experimental group had a slight increase in empathy, with an average N-Gain Score of 0.21, which is considered low. However, a statistical test showed a significant improvement in empathy in this group, with a Sig. (2-tailed) value of 0.001 < 0.05, indicating that the videos made a meaningful difference. The control group did not show any significant change. This study concludes that animated media can be an effective tool to enhance empathy among adolescents, although the effect was small. It suggests that animated videos could be used in educational and psychological practices to help develop empathy in adolescents, which is crucial for preventing bullying in schools.

Published: November 2024

Green accounting, also known as environmental accounting, focuses on a more comprehensive view of an organisation's financial performance by taking into account environmental impacts. The batik business has a considerable influence on the preservation of nature due to several factors related to the production process and the raw materials used.This research was conducted on MSMEs batik business in the Madura region. This type of business was chosen because this type of business has a considerable influence on natural sustainability. This research explores the extent to which business people as one of the main elements care about the environment and know and have knowledge about green accounting. This research uses a qualitative method with a case study approach. Data collection techniques are observation, interview, and documentation. Data analysis was carried out with the stages of data reduction, data presentation, and conclusion drawing. The results of the study state that batik business actors in the Madura region have a good understanding and concern for protecting their business environment as a form of green accounting implementation. This understanding is evidenced by how business actors understand and allocate business costs and environmental costs, and separate personal funds from business funds. Although their understanding of specific business and environmental costs is limited, they already understand that environmental costs are costs charged to their business as a form of responsibility. The implications of this research are expected to be useful in realising optimal green accounting practices, not only for batik business MSMEs but also for business actors in other business fields.

This means that Madurese women realize how important education is for women. Through education, of course women will not be left behind in the educational aspect. Second, educational discrimination influences sustainable regional development (SDGs). Contributions at the theoretical level are managerial and public sector theories related to the use of the Sustainability Based Regional Development (SDGs) approach model. This means that through sustainable-based regional development (SDGs) we can minimize educational discrimination against women, because one of the Sustainable Development Goals (SDGs) targets is to create quality education, which can be done by ensuring the implementation of education that is inclusive and of equal quality, as well as supporting lifelong learning opportunities for everyone. SDGS consists of three indicators, namely WiD, WaD and GaD. The next research opportunity is to be able to add research variables, and to use a qualitative research approach by conducting in-depth interviews with informants related to the research object.

Authors: Baitia Rohmatul , Kurniyanto Ifan Rizky
Published: November 2024

The attitude of farmers as the main actors of agriculture is an important factor in determining the decision to use certified seeds. Farmers' behavior in making decisions is also a consideration of the amount of demand for rice seed products on the market. Thus, it is important for producers to understand precisely the needs of farmers, so that both farmers and producers do not experience losses. The purpose of this study is to measure the behavior of farmers in the selection of certified rice seeds and analyze the preference groups that influence farmers' intentions in the selection of seeds used. Research data was collected using purposive sampling with a total sample of 52 farmers. Data measurement uses the Theory of Reasoned Action model approach, where behavioral are measured from attitudes and subjective norms. The results showed that farmers' behavior to choose certified rice seeds was more influenced by farmers' attitudes with attributes of certified rice seeds that were rated highly agreed by farmers, namely productivity and rice texture. While the preference group that is a factor in the selection of certified rice seeds used with a strongly agreed category is family and friends. In addition to considering in terms of seed attributes, producers should be able to provide the types of seeds that are much needed by farmers and maximize promotion through approaches with farmer groups in Burneh District.

The aim of this study was to determine the substrate concentration and fermentation time to produce high activity of cellulase enzyme. Crude cellulase production in different substrate concentrations and fermentation times used a factorial randomized block design (RBD) consisting of two factors. The first factor was the substrate concentration which consisted of 4 levels: 2%, 4%, 6%, and 8% (w/v). The second factor was the fermentation time which consisted of four levels: 24 h, 48 h, 72 h, and 96 h. This study used B2S8 cellulolytic bacterial isolates which had the highest value of cellulase activity and the highest rate of cellulose degradation in previous studies. To test the enzyme activity, this study used carboxymethyl cellulose (CMC), citrate buffer, and cellobiose. Protein levels were analyzed using the Lowry method. The results showed that the highest cellulase activity was under 8% (w/v) substrate concentration and fermentation time 96 h which resulted in endoglucanase activity was 0.1320 IU/mL, exoglucanase activity was 0.0320 IU/mL, β-glucosidase activity was 0.0172 IU/mL, dissolved protein level was 0.1719 mg/mL, specific endoglucanase activity was 0.9804 IU/mg, specific exoglucanase activity was 0.2730 IU/mg, and specific activity of β-glucosidase was 0.1260 IU/mg. The ability of B2S8 bacteria shows great potential for cellulase enzyme production and can be applied in lignocellulose hydrolysis.

Food waste is a significant issue in Indonesia, with approximately 1.3 billion tonnes generated annually. A substantial portion of this waste originates from restaurants, often due to customers not finishing their meals. The contribution of this research is to provide proposals for handling food waste. This study employs Interpretative Structural Modelling (ISM) to identify and analyse factors influencing food waste in restaurants. The study identifies 23 factors affecting food waste in restaurants, which are classified using the SCOR method. ISM analysis reveals a hierarchical structure of these factors based on expert opinions. Food packaging is identified as a critical factor contributing to food waste due to its potential to damage food. Addressing packaging issues should be prioritized to reduce food waste, whereas factors related to food delivery have a relatively lower impact.

Blue swimming crab (BSC) catch is considered a highly perishable product; initial on-board processing, including steaming and cool preservation, is necessary to maintain quality. Traditionally, a fire stove conducts the BSC steaming process; this can pose a fire hazard on a wooden boat. Further, the ice-cooled boxes stored the steamed BSC, which could melt and seep into the BSC meat. As an innovation, we could change the BSC steaming process using electronic devices such as electronic stoves and cooling preservation using electric cold storage; both alternatives require electricity as a power source. One electricity source is converting solar energy using solar panel systems (PV). This research aims to design a PV system for the initial on-board processing of BSC and storage, using simulations with PVsyst 7.2 software, to serve as a reference for fishermen, entrepreneurs, and relevant stakeholders. A quantitative method generates wiring diagrams, installation diagrams, and placement plans for the photovoltaic (PV) system and electronic equipment. The technical and economic analyses determined the viability of utilizing the photovoltaic system design. The research result was a complete off-grid PV system design, producing 1740 kWh/year of electricity with a specific yield of 1450 kWh/kWp/year. The investment in the off-grid PV system reaches the break-even point in 2043, with a profit of 68,534 IDR. This off-grid PV system design can supply the electricity needed for electronic equipment used in the initial on-board processing of BSC catch.
"Be Careful!”: Justification of work safety culture for elderly siwalan farmers
Authors: Kristina Anita , Jumali Muhamad Abdul
Published: November 2024

Many farmers, including Siwalan farmers, are over 50 years old. They climb Siwalan trees, which can reach a height of 15-30 meters, using simple tools. Despite the high risk of injury, they continue to make this work their main job. The research employs a qualitative approach using ethnomethodology methods. Data was collected through in-depth interviews with 10 Siwalan Farmers in Aeng Panas Village, Madura, Indonesia, who are aged between 50 and 65 years. The conceptual framework of work safety culture is used to describe and explain how work safety culture can be identified through the work habits of older farmers. Two key points emerged from the findings: 1) The appreciation of safety values is fostered through strong interactions between farmers and their wives/families, which are characterized by trust, experience, and hope. This interaction cultivates a caring attitude that motivates individuals to prioritize safety and avoid work accidents. Common expressions such as "Be careful!" strengthen the mindset of old farmers. 2). Efforts to recognize and reduce dangers are carried out through work habits that only use simple tools, but they have a strong belief that whatever happens is God's destiny. The findings of this research have contributed to the fact that the construction of work safety culture is oriented towards humanistic rationality, namely awareness that arises from the word "Be careful!". The tradition of love from a wife and family is a strong psychological construct and will ultimately strengthen a work safety culture.
