Traditional fermented foods made from glutinous rice play a significant role in Indonesia’s local food system, with fermented glutinous rice known as tape ketan being one of the most popular products. Tape ketan is produced through a fermentation process using traditional starter cultures that involve diverse microorganisms, resulting in distinctive sensory characteristics. This review article aims to examine and synthesize previous studies related to the fermentation process of tape ketan and the characterization of metabolites formed during fermentation. The study employed a qualitative approach with descriptive analysis based on a literature review of relevant national and international scientific journals. The findings indicate that tape ketan fermentation involves starch hydrolysis, sugar fermentation, and the formation of primary and secondary metabolites influenced by fermentation time and microbial composition. Primary metabolites such as simple sugars, organic acids, and alcohol contribute to the basic sensory attributes of the product, while secondary metabolites including phenolic compounds and bioactive components enhance its functional potential. The characterization of these metabolites demonstrates that tape ketan is not only a traditional fermented food but also has promising potential for development as a value-added functional food based on local wisdom.

Maddoja Bine is an agrarian tradition of the Bugis people in Soppeng Regency, performed before sowing rice seeds in the nursery. This ritual contains social, religious, and cultural values ​​deeply rooted in the belief system and social structure of the local community. This study aims to examine the history, ritual procession, socio-religious dimensions, and the dynamics of change and preservation of the Maddoja Bine tradition through an ethnographic approach. The research method used is a literature study by reviewing various national and international journal sources published in the last ten years, supplemented by a qualitative analysis of the results of previous research. The results of the study indicate that Maddoja Bine functions not only as an agricultural ritual, but also as a medium for collective prayer, a means of transmitting moral values, and strengthening social solidarity in the Bugis community. Along with social change, agricultural modernization, and religious influences, this ritual has undergone transformations in form and practice, but still maintains its core values ​​as a local cultural identity. Thus, Maddoja Bine is a tradition that is dynamic and adaptive to changing times, yet remains relevant as an intangible cultural heritage of the Bugis community.

This research aims to explore how Integrated Marketing Communication (IMC) is applied to enhance the sales performance of local rice products in the midst of competition with well-established national brands. Intensified competition arises due to the increasing presence of rice products from other regions as well as premium national brands that offer added value. These market dynamics underscore the importance of strategic marketing communication, especially in designing messages, selecting appropriate media channels, and applying the right consumer engagement approach to strengthen brand awareness and loyalty.A descriptive qualitative method was employed, utilizing a case study approach on a local rice producer in Tabanan Regency. Data collection involved in-depth interviews, field observations, and documentation related to promotional and sales activities, which were then analyzed through data reduction, data display, and conclusion-drawing stages.The results demonstrate that the coordinated use of IMC elements such as advertising, sales promotion, public relations, digital marketing, and word-of-mouth has contributed significantly to improving brand perception and market competitiveness. Ultimately, this study suggests that adopting a consistent and well-structured IMC strategy is essential for local rice producers to sustain their presence and achieve growth amidst the dominance of national rice brands.

Cilacap Regency in Central Java Province is recognized as an important contributor to national food production due to its extensive agricultural land and reliance on technical irrigation systems. The performance of irrigation networks, particularly secondary channels in the Serayu Irrigation Area (DI), is essential in regulating water levels to support agricultural activities in Sampang and Karangasem Villages. Variations in rainfall and field conditions often create water level differences that disrupt irrigation distribution, reducing water flow efficiency to rice fields and lowering productivity, especially during the dry season. This study aims to design secondary irrigation channels capable of maintaining stable water levels based on irrigation requirements. The research applies a descriptive quantitative method using rainfall data from BMKG, along with land area and elevation data interpreted from Google Earth imagery in 2025. The data were analyzed using probability and Thiessen polygon methods to estimate design rainfall, determine water availability, calculate irrigation demand, and plan channel dimensions. The analysis shows that Secondary Channel BGS 4.B serves an irrigation area of 103.57 hectares with a planned discharge capacity of 0.0343 m³/s. The channel design includes a base width of 0.65 meters and a water depth of 0.65 meters, with water surface elevations of 14.27 meters upstream and 13.15 meters downstream. Evaluation using a 10-year rainfall return period of 151.677 mm shows the channel can convey discharge effectively while maintaining water levels below the embankment, ensuring reliable irrigation distribution.

This study aims to analyze production cost efficiency through the use of self-formulated feed based on rice bran in laying hen farming in Kutamandiri Village. Feed costs represent the largest component of production expenses in laying hen enterprises, reaching up to 60–70% of total operational costs. The research employed a descriptive quantitative approach using primary data collected through observation, interviews, and cost-revenue recording during one production period. Data were analyzed using cost structure analysis and Revenue-Cost (R/C) ratio to determine business feasibility. The results indicate that the use of rice bran-based self-formulated feed reduced feed costs and lowered total production expenses. The calculated R/C ratio was 1.43, indicating that the enterprise is financially feasible and profitable. Additionally, the findings suggest that utilizing locally available feed resources such as rice bran can improve cost efficiency, reduce reliance on external feed supplies, and enhance the sustainability of small-scale laying hen enterprises. This research provides valuable insights for farmers in Kutamandiri Village and other similar agricultural communities looking to optimize production costs and improve their profitability by adopting cost-effective, locally sourced feed options.

The decline in seed quality due to storage beyond the shelf life is a major problem in rice cultivation. One effort that can be made to improve seed viability is through invigoration techniques using natural ingredients, such as bean sprout extract (Phaseolus radiatus), which contains growth hormones. This study aims to analyze the effect of bean sprout extract on the viability of Ciherang rice seeds that have exceeded their shelf life and to determine the best treatment. The study was conducted from August to November 2024 at the Biology Laboratory of the UPTD Seed Center, Supervision and Certification of Agricultural Seeds of Gorontalo Province. The study used a two-factor Randomized Block Design (RBD) with bean sprout age (3, 5, and 7 days after sowing) and bean sprout extract concentration (20 g/L, 40 g/L, and 60 g/L) as factors, with four replications. The parameters observed included germination rate, maximum growth potential, and sprout length. The data were analyzed using ANOVA and DMRT post-hoc test at a 5% level. The results showed that bean sprout extract had a significant effect on all observed parameters. The treatment of 5-day-old bean sprouts with a concentration of 20 g/L gave the best results with a germination rate of 95.5%, maximum growth potential of 98.5%, and the highest sprout length. Sprout extract has the potential to be used as a natural alternative to improve the quality of rice seeds that have passed their storage period.

The increasing need for insulation in electric power systems encourages the discovery of high-performance and sustainable dielectric materials. This study presents a Literature Review of biomass-based composite insulator research from 2018-2025 to synthesize the effect of filler type and treatment on the electrical, thermal, and mechanical properties of polymer composites. Literature was analyzed from reputable databases with inclusion criteria, and thematic analysis data extraction. Processing methods generally include washing, acid/alkali treatment, calcination, and advanced production techniques such as sol-gel and ultrasonication, integration of biomass fillers especially at low fractions (3-7%). The results show 1) the dominance of the use of rice husk as a source of biosilica for the main matrix filler of the insulator. 2) the performance of biomass composite insulators is highly dependent on the quality of purification, particle size, and surface modification of the filler. 3) there is a significant increase in the insulator's breakdown strength, resistivity, and thermal stability with the addition of biomass fillers to the main matrix. 4) the long-term stability of biomass materials against humidity and thermal aging has not been evaluated in depth.  

This study aims to design, implement, and compare the performance of the Backpropagation algorithm from Artificial Neural Networks and the Seasonal Autoregressive Integrated Moving Average (SARIMA) model in predicting the optimal daily rice requirement at Grillme Restaurant in Pontianak. The main problem faced by the restaurant is the uncertainty in determining the required daily rice stock, which periodically results in either understocking (shortage) or overstocking (wastage), leading to operational losses. To address this, the study utilizes historical daily rice sales data from January 2023 to April 2025 as the database for training and testing both predictive models. The SARIMA approach is employed to capture time series components (trend and seasonality), while Backpropagation is utilized to model non-linear patterns. Comparative test results indicate that the SARIMA model achieved superior accuracy compared to the Backpropagation model. This is confirmed by the Mean Absolute Percentage Error (MAPE) value of the SARIMA algorithm being 17.35%, which is lower than the MAPE value of Backpropagation at 19.62%. The MAPE values obtained by both models demonstrate good predictive capability, but it is concluded that SARIMA is more recommended for a more efficient and planned management of rice stock at Grillme Restaurant in Pontianak.

Continuous chemical control of rat pests (Rattus spp.) can sometimes lead to resistance and resurgence problems, and even some cases of inaccurate targeting ultimately killing livestock. The idea of ​​​​repelling rats in rice fields using vibrations of crickets and other natural animals transmitted via radio has been done and the results are quite optimal for rat control, but it has not been done in corn cultivation. The purpose of this study was to determine the effect of cat sound audio on the intensity of rat pest attacks (Rattus spp.) in corn (Zea mays L.) plantations. The research location was in a farmer's land owned by a farmer in Dagan Village, Solokuro District, Lamongan Regency. Determination of sampling points using the diagonal method, each into 5 sub-observation plots. In each sub-plot, markers were placed as sampling points. Audio with cat and bird sounds was played continuously from 05.00 pm - 07.00 am. Observations were conducted at 7:00 a.m. at all sampling points at 30 and 60 days after planting. Observations were conducted for three days using audio and three days without audio. Damage symptoms were observed directly at each sampling point. Corn plants showing symptoms were then recorded and analyzed using the Damage Intensity formula. Observations showed that the use of cat sound audio was able to reduce the level of rat infestation. At 30 days after planting, the damage percentage was reduced by 8.33%. Meanwhile, at 60 days after planting, the damage percentage was reduced by 18.33%.

This literature study examines hydroponic solutions (urban agriculture), particularly through hydroponic methods, as a response to the issue of significant urban agricultural land shrinkage and land conversion. Data shows a drastic reduction in rice fields in Sukawati District, Bali, from 497.24 Ha in 1985 to only 211.42 Ha in 2016, accompanied by a change in the profession of residents from farmers to entrepreneurs. This land conversion not only reduces agricultural areas but also has the potential to eliminate farmers' livelihoods. The method used is a literature review (narrative review) to collect and analyze studies related to the use of hydroponics in maximizing limited land in urban areas. The results of the discussion focus on hydroponic training provided to housewives from the Family Welfare Movement (PKK) and the City Youth Organization (Karang Taruna). This training aims to empower and utilize the free time of housewives, covering materials from the basic concepts of hydroponics, seed preparation, planting, maintenance, to harvesting. Hydroponic practices have been responded to positively by residents, and the PKK/Karang Taruna group is prepared to become mentors for other members. The benefits of hydroponics were emphasized as a highly efficient cultivation method, capable of saving up to 70-90% of water, enabling year-round food production, and providing faster and higher plant growth and yields. The outcome of this activity was the establishment of a communal hydroponic garden and each member's plan to grow hydroponically independently, demonstrating the success of hydroponics as a real solution to improving food security and sustainability in dense urban environments.

Rice is a staple food for nearly two-thirds of the world's population, including Indonesians. Rice generally has a high glycemic index (GI) and cannot be consumed by diabetics.  Pratanak rice has a low GI, so it is recommended for diabetics. The study aimed to evaluate the effect of parboiled rice on the amount of LAB (Lactic Acid Bacteria), pH, and SCFA (Short-Chain Fatty Acids) of diabetic experimental animals. The research method consisted of 6 groups of rats with groups 1 (Cr and Mg fortified parboiled rice), 2 (Cr, Mg and cinnamon fortified parboiled rice), 3 (nonfortified parboiled rice), 4 (ciherang rice), 5 (standard feed for healthy rats), 6 (diabetic rats). All groups of rats were adapted for 3 days with standard feed and treatment for 14 days. LAB, pH, and SCFA were analyzed, statistical tests using One Way Anova if significantly different, followed by DMRT test. Giving chromium, magnesium, and cinnamon fortified rice gave a significant difference in the amount of LAB, pH, and SCFA feces between the treatment group and the control group. Thus, pre-cooked rice fortified with Cr, Mg, and cinnamon has the potential to be a healthier food option for individuals with diabetes.

One of the various salted egg products with smoking methods is smoked salted eggs which have a distinctive aroma and taste. This study aims to determine the effect of smoking and storage time  and its  interaction on  smoked salted  eggs  with on  physical  and  chemical  properties, total microbes as well. This research is experimental by using ducks eggs and a mixture of coconut shells and fibers, and rice husks as smoke fuel. The experimental design used is Randomized Complete Block Design (RCBD) with a 3x5 factorial pattern. As the first factor (P) is the smoking time which consists of P0= 0 hours, P1= 12 hours, P2= 15 hours while the second factor (H) is the storage time which consists of H0= 0 days, H1=7 days, H2= 14 days, H3= 21 days, and H4= 28 days. The variables observed were egg weight, albumen and yolk pH, moisture content, protein, and total microbial colony of smoked salted eggs. The results of the study were that the smoking time of 15 hours resulted in the lowest weight of smoked salted eggs (56.13g), while the storage time decreased the pH of albumen. Smoked salted duck eggs have a moisture content of 58.435-67.149%. The length of smoking increases the protein level. Salted duck eggs with a smoking time of 15 hours have the highest protein content, which is 15.39%. however, the duration of smoking and storage did not affect the total microbes of smoked salted eggs and there was no interaction between the duration of smoking and the duration of storage on the physical, chemical and total microbial properties.

Business ventures are activities carried out by individuals or organizations involving the production, sale, purchase, or exchange of goods and services, with the aim of generating profit. A basic necessities store (commonly known as a “sembako” store in Indonesia) sells daily staple needs, especially the nine essential commodities (sembako), which include items such as rice, sugar, cooking oil, eggs, salt, and other key food ingredients. UD. Putri 2, located in Dusun 1A, Sumber Harapan Village (21261), Tinggi Raja Subdistrict, Asahan Regency, was established in 2018 and has since become an essential part of the local community. This has required UD. Putri 2 to constantly monitor their stock inventory. However, the company still faces inefficiencies in managing sales data processing, which often leads to inventory shortages. When the supply of goods is insufficient to meet customer demand, customers may turn to other stores. If this occurs repeatedly, the store risks losing profit due to the unavailability of goods. Supply Chain Management (SCM) refers to the integrated processes and production activities starting from the acquisition of raw materials from suppliers, the value-adding processes that turn raw materials into finished products, the inventory storage process, and the distribution of finished goods to retailers and consumers. The implementation of SCM can optimize inventory management of staple goods, minimize inventory costs, and improve supply chain efficiency at UD. Putri 2.

The instability of the climate is becoming increasingly prominent across Southeast Asia, creating uncertainty in agricultural systems that are highly dependent on seasonal weather patterns. Indonesia, where rice remains the primary staple food, is particularly vulnerable to the effects of rising temperatures and rainfall deficits. This study applies the Seasonal Autoregressive Integrated Moving Average (SARIMA) model to predict rice production while incorporating indicators of extreme climate anomalies. Using publicly available datasets, including FAOSTAT production statistics, NOAA rainfall and temperature anomalies, and climate indices from the World Bank, this model was developed following the Box-Jenkins procedure. Among the configurations tested, the SARIMA model (1,1,1)(0,1,1)₁₂ showed the strongest performance, reflected in a MAPE of 4.62% and low RMSE values. The model indicates that significant El Niño events can reduce annual rice production by 3–7%, while wetter La Niña conditions may support production recovery. These findings highlight the importance of integrating climate-sensitive data into agricultural forecasting. The model presented here could support early warning systems, adaptive farming strategies, and long-term food security planning in Indonesia.

The informal institution of mutual cooperation (gotong royong) in the rice farming community in Bhera Village, Mego District, Sikka Regency, remains the main foundation of social solidarity and the sustainability of agricultural activities even though modernization and the use of labor have begun to shift traditional values. A qualitative approach with a case study method was used to explore the role, form, and meaning of mutual cooperation in agricultural practices. Data were collected through in-depth interviews, participant observation, and documentation studies of rice farmers who are active in mutual cooperation activities. Data analysis was carried out through reduction, presentation, and drawing conclusions using triangulation techniques to ensure the validity of the findings. The results show that mutual cooperation is manifested in every stage of farming, from uprooting seedlings, planting (planting), clearing weeds, to harvesting, which is carried out voluntarily and in turns through the Irutan Tradition system. This institution functions as a collective work mechanism that reduces production costs, overcomes labor shortages, and strengthens social ties between farmers. Beyond its economic function, mutual cooperation has profound social and cultural significance as a symbol of brotherhood, togetherness, and collective responsibility in maintaining the sustainability of local wisdom and the resilience of farming communities amidst social and technological change.

This study aims to analyze corn consumption substitution as an alternative carbohydrate source and to measure the demand elasticity of corn in response to fluctuations in corn and rice prices at Ciawitali Market, Garut Regency. Primary data were collected through observations and interviews, along with secondary data from West Java Central Statistics Agency processed using simple linear regression and cross-elasticity analysis with SPSS. Results show that changes in corn prices explain 99.7% of variation in corn demand with a positive coefficient of 0.827, indicating a substitution effect with rice, which experienced a concurrent price increase. The cross-elasticity value of 1.64 confirms the elastic substitution relationship between corn and rice. These findings highlight the potential of corn as a substitute for rice in maintaining stable food consumption despite fluctuations in staple commodity prices.       

This study explores the Village Cross as a symbol of inculturation, integrating Catholic faith with the Nosu Minu Podi ritual in Dusun Perintis, Balai Sebut Village, Sanggau Regency. Nosu Minu Podi, a post-harvest rice ritual, originally centered on the ancestral statue (Pantak) as the main focus of worship. The introduction of Catholicism led to a symbolic transformation, replacing the Pantak with the Village Cross while maintaining ancestral values and harmonizing them with Catholic practices. This research uses a qualitative approach combining ethnography and contextual theology. Data were collected through participatory observation, semi-structured interviews, and field documentation. Findings reveal that the Village Cross serves dual functions: as a religious symbol affirming God’s presence and spiritual protection, and as a marker of social and cultural identity. This transformation strengthens community solidarity, preserves traditional practices, and provides a medium for faith formation among youth. The study highlights that inculturation enables the integration of local traditions with religious teachings, creating space for contextual, inclusive, and practical pastoral approaches. It contributes to scholarly understanding of the interplay between religion, culture, and community identity, emphasizing the enduring relevance of local wisdom in contemporary religious practice.
