The quality of rice that is suitable for consumption, one of which is determined by the absence of associated components when the rice is in storage. Rice storage is carried out by means of long shelf life and good rice quality. Damage to rice due to pest attacks causes a decrease in quality and quantity. Environmentally friendly efforts are needed to control the rice weevil Sitophilus oryzae using vegetable materials. This study sought to ascertain the death rate of rice weevils treated with lemongrass stem (Cymbopogon citratus), bay leaves (Syzygium polyanthum), and pandan leaves (Pandanus amaryllifolius). The study employed a fully randomized design with three treatments in the form of simplicia plant components. There were 21 study units because each treatment included seven repetitions. Each treatment used 20 rice weevil imago breeding results which were infested in a jar containing 200 g of rice for 4 weeks in the laboratory. The use of pandan leaf, bay leaf, and lemongrass simplicia at 7 days after treatment showed the proportion of rice weevil mortality was 59,29%, 39,29%, and 50,00%, respectively. As for the observations of 14 day after treatments, 21 day after treatments, and 28 day after treatments showed that the mortality rate of all rice beetles was above 50%. Regarding the percentage of rice powder, hollow rice, and rice weight loss, the findings of observations on rice weevil mortality did not reveal any significant variations across all treatments.

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.       

Manual post-harvest paddy stirring requires significant time and labor and often results in uneven mixing, which can affect grain quality. To address this issue, this study designed and implemented a prototype of an Internet of Things (IoT)-based paddy stirring robot to simplify the process and improve efficiency. The system utilizes an ESP32 microcontroller as the main controller, DC motors as the stirring mechanism, and an IoT module for wireless connectivity to a mobile application. The research stages included hardware design, control system programming, IoT platform integration, and performance testing. Testing was conducted to evaluate response time, mixing uniformity, and power consumption. The results showed that the system could be operated remotely via a local Wi-Fi network with an average delay of less than 1 second, enabling real-time control. The prototype successfully stirred 0.3 kg of paddy with a mixing uniformity rate of 92% and an average power consumption of 12 watts. The application of IoT in the paddy stirring mechanism significantly improved time efficiency, reduced manual labor requirements, and maintained grain quality compared to traditional methods. These findings indicate the potential for further development into a large-scale automated paddy processing system with integrated humidity and temperature sensors for real-time quality monitoring, supporting the modernization of post-harvest processing through digital technology.

Black sticky rice tapai is a traditional Indonesian fermented food that has long been consumed by the public for its distinctive taste and high cultural value. However, with the increasing demand for functional foods and natural-based products that can support health, attention for black sticky rice tapai has shifted from being simply a traditional food to an object of scientific study in the nutraceutical field. Black sticky rice, the basic ingredient for tapai, contains important bioactive compounds such as anthocyanins, flavonoids, B-complex vitamins, and soluble fiber, which have been shown to play a role in lowering cholesterol levels, inhibiting LDL cholesterol oxidation, and increasing HDL cholesterol levels in the blood. The fermentation process further enhances the biological activity of these compounds, making black sticky rice tapai have a higher therapeutic value than ordinary black sticky rice. The purpose of this study was to examine the potential of black sticky rice tapai as a natural, tradition-based solution for lowering cholesterol levels, while also supporting the development of local foods into modern health products that are safe, effective, and affordable. The study was conducted using a descriptive literature review method of various scientific articles, textbooks, and relevant research results that discuss the nutritional content of black sticky rice, the benefits of fermentation, and the effect of active components on lipid metabolism. The study results show that regular consumption of black glutinous rice tapai has the potential to lower total and LDL cholesterol levels and increase HDL through a combination of antioxidant effects, cholesterol binding by fiber, and increased fat excretion. In addition, the potential of black glutinous rice tapai as a nutraceutical is also relevant in supporting the preservation of local-based culture and food independence.

Background: Stunting remains a serious public health issue in Indonesia, particularly in rural areas such as Ambasea Village, Laeya Sub-district, South Konawe Regency. Stunting, or chronic growth failure in children due to prolonged malnutrition, generally occurs during the first 1,000 days of life. In Ambasea Village, this problem is exacerbated by irregular eating patterns among toddlers, consumption of low-nutrient foods, and poor hygiene behaviors. Toddlers frequently consume unhealthy snacks, reject main meals such as rice and side dishes, and rarely wash their hands with soap before eating or after using the toilet. Furthermore, limited access to basic sanitation—such as the lack of proper latrines and adequate wastewater disposal systems (SPAL)—also contributes to the high risk of infections that disrupt nutrient absorption, increasing the likelihood of stunting in children. Objective: This study aims to describe the environmental health conditions contributing to the incidence of stunting among children aged 0–2 years in Ambasea Village. Methods: The research used an observational analytic method with a quantitative cross-sectional design. The study involved 54 toddlers identified as stunted. Data were collected through structured interviews with parents or caregivers and direct observation of the household and surrounding environmental conditions. Results: The results showed that 66.5% of households did not have access to proper latrines, and 70% lacked adequate wastewater disposal systems. However, 87% had access to clean water, and 85% of respondents demonstrated good handwashing behavior. Conclusion: The environmental health conditions in Ambasea Village reveal ongoing challenges related to latrine ownership and wastewater management. Although clean water access is relatively good and hygiene practices among residents are fairly positive, improving sanitation infrastructure remains crucial. Enhancing these conditions is expected to significantly reduce the risk of stunting among toddlers in the area. Collaborative efforts involving local government, health workers, and the community are essential to create a healthier environment for early childhood development.

The Rice Bowl (Nasi Mangkok) culinary business in Indonesia has experienced rapid growth after the COVID-19 pandemic and has become a key part of the modern food industry, meeting consumer demand for convenience and taste. Since 2020, rice bowl sales have continued to rise annually, driven by shifting consumption habits toward food delivery services like GoFood and GrabFood. Despite this trend, academic studies on the rice bowl business remain limited. Classified as convenience food, rice bowl consumption has increased by over 10% from 2019 to the projected figures in 2025. Sales volume has risen from 1.5 billion portions in 2020 to over 3 billion in 2025, with an annual growth rate of 10–15% and estimated revenues between IDR 15–20 trillion per year. With rising demand, many rice bowl brands have entered the market. However, consumers often struggle to decide which brand to choose, as purchasing decisions are influenced by multiple factors. This study analyzes consumer behavior influencing rice bowl purchasing decisions, focusing on cultural, social, psychological, and personal factors, with a case study in Sidoarjo Regency, East Java. Using an explanatory research design, the study surveyed 161 consumers across four sales locations.The F-test results show that all four variables simultaneously have a significant positive effect on purchasing decisions (at the 99% confidence level). However, the t-test results reveal that the cultural factor (X1) negatively influences purchasing decisions, while social, psychological, and personal factors have a positive impact. Among these, the psychological factor (X3) is the most dominant, highlighting the importance of consumer motivation and perception in shaping buying behavior. Enhancing this factor can support the sustainable growth of rice bowl businesses in Sidoarjo.

Internal combustion engines generate thermal energy through the combustion of an air-fuel mixture. The incoming air must be filtered, as it contains impurities and particles. While air filters are commonly made from paper, they can also be developed using organic waste materials such as sugarcane bagasse and rice husk. This study aims to analyze the effect of biocomposite air filters on engine power, torque, and specific fuel consumption (SFC), by varying the material composition and the number of pleats, and comparing the results with those of a standard air filter. The method used is a quantitative experimental approach involving dyno testing on a 150 cc motorcycle engine. The tested material compositions include 50:50, 40:60, 30:70, 60:40, and 70:30 (sugarcane bagasse\:rice husk), with pleat counts of 28, 26, and 24. Results showed that the biocomposite filter with 28 pleats and a 30:70 composition delivered the best performance, producing 18.47 Hp and 16.66 Nm of torque—higher than the standard filter’s 17.98 Hp and 15.52 Nm. In terms of fuel efficiency, the 26-pleat filter with a 50:50 composition recorded the lowest SFC at 41.90 g/kWh, significantly better than the standard filter’s 53.03 g/kWh. Conversely, the 60:40 composition resulted in the highest SFC due to increased airflow resistance.

Food is a basic need that must be met by every individual. In Indonesia, rice is still the main staple food, but the shift in consumption to rice and wheat which are imported foodstuffs raises concerns about food security. Therefore, the development of local food alternatives such as MOCAF (Modified Cassava Flour) flour from cassava is important. In this practicum, MOCAF flour was made through a cassava fermentation process, followed by making onion cakes using the MOCAF flour. Organoleptic tests and XRF tests were carried out to evaluate the quality of MOCAF flour. The results of the practicum showed that the substitution of MOCAF flour in making onion cakes can produce low-gluten products that have the potential to be a sustainable food alternative.

This activity is carried out using interactive storytelling methods using props, discussions and using interactive games. Evaluation is also carried out informally through observations during discussions and games, and by giving short questions to children about their stages and their respective roles. This learning activity contains values ​​from the SDGs, namely ending hunger (SDGs 2) and sustainable consumption (SDGs 12). The purpose of this service is for elementary school children to know the journey of rice from the rice fields to the dining table by using pictures and telling stories for each group, in addition to elementary school children to work together and need each other..    

The purpose of this study was to determine the performance of sheep with the addition of fermented rice bran in the ration. This research was conducted in August-October 2023 at the sheep farm in Putra Buyut Village, Gunung Sugih District, Central Lampung Regency. In this study, 12 sheep were used with the age of 2 years and body weight of 20-23 kg. This study uses fermented rice bran as an addition to sheep rations, the addition in the ration with different percentages, namely P0 (forage feed without the addition of fermented rice bran), P1 (forage feed with the addition of 10% fermented rice bran), P2 (forage feed with the addition of 15% fermented rice bran), P3 (forage feed with the addition of 20% fermented rice bran). This study used a complete randomized design (CRD) with 4 treatments and 3 replicates. Parameters observed in this study were feed consumption, body weight gain and feed conversion. The results of this study showed that the provision of fermented rice bran in the ration had no significant effect (P>0.55) on feed consumption, body weight gain, and feed conversion.  The highest average weight gain was in P0 (150.67).

An examination of the variables affecting rice output and farmers' income levels serves as the driving force behind this study. One of the settlements where people live and work is this one. Using multiple linear regression methods and confirmatory factor analysis (CFA), the study aims to ascertain and assess the effects of fertilizer use, capital, productivity, land, distribution, price, demand, and consumption on farmers' income levels. One hundred farmers served as the sample size. Questionnaires were sent in order to gather data, and SPSS version 24.0 was used for data processing. According to the findings of experiments conducted using hypothesis testing, farmer income is significantly impacted by the factors of production, consumption, land, and prices. Next, the variables Farmer income is not significantly impacted by fertilizer use, demand, distribution, or capital. Four factors are suitable to influence income, according to the research's findings. The first component, productivity, has a value of 0.912; the second, consumption, has a value of 0.764; the third, land, has a value of 0.848; and the fourth, price, has a value of 0.864. The Rotated component matrix value indicates that there are eight factors. The government must work to inspire and excite the people to boost the wealth of farmers in Sei Rotan village, and it is hoped that farmers would keep increasing the productivity of their rice output.

As people's consumption levels increase, the plastic waste produced will also increase. It's normal if in the future it becomes a serious environmental problem. We need a technology that is able to replace plastic waste into products that have a long life so that they do not return to waste in a short time. Making paving block products from plastic waste is another way of utilizing plastic waste over a long period of time, in order to increase utilization efficiency and reduce the environmental burden on plastic waste and form innovative products into building materials. The most important problem with plastic is plastic waste which cannot be decomposed naturally. Cleaning up plastic waste takes a very long time, and also the use of plastic can hardly be regulated. Based on the results of surveys, interviews and observations conducted on the community around Kuala Village, the community's awareness of waste processing is very minimal and there are lots of piles of plastic waste which can have a negative impact on health and disrupt the preservation of environmental functions, including residential environments, forests, rice fields, and rivers. To reduce the volume of plastic waste that is not managed properly, efforts are being made to utilize plastic waste to make paving blocks in Kuala Lemang Village. to explore the potential for using plastic waste as an alternative material in making environmentally friendly and sustainable paving blocks. Plastic waste collected from the surrounding environment is processed into mixed materials in making paving blocks. This process involves chopping, mixing with conventional materials such as sand, and testing the strength of the final product. Public acceptance of plastic-based paving blocks has proven positive, especially after trials in the local environment. This research contributes to better plastic waste management and offers new economic opportunities in the construction sector, while supporting sustainable development.

Rice imports have been demonstrated to influence the Farmer's Exchange Rate (NTP) significantly. A reduction in rice imports by 356,286.2 tons in 2020 corresponded with a decline in NTP to 101.65. In contrast, per capita, weekly rice consumption did not exhibit a statistically significant impact on NTP, as evidenced by the lowest consumption in 2019 (1.504 kg), while the NTP remained at 104.46. On the other hand, rice productivity was found to have a notable influence on NTP, with trends in productivity closely mirroring those of the NTP. The harvest area, however, did not present a significant correlation with NTP, as demonstrated in 2019 when an increase in harvest area did not prevent the NTP from remaining at a lower level of 104.46. Lastly, rice production had a significant effect on NTP, with increases in production during 2021 and 2022 leading to subsequent increases in the NTP.                  

Rice prices in Indonesia have experienced significant fluctuations from 2019 to 2023, influenced by factors such as production, consumption, imports, international prices, and crop damage. The highest rice production was recorded in 2022 at 31,540,522 tons, while the lowest production occurred in 2023 at 31,101,285 tons. The highest rice consumption was in 2023 at 30,616,081 tons, and the lowest was in 2019 at 28,930,000 tons. The highest rice imports were in 2023 at 2,715,854 tons, and the lowest was in 2019 at 6,197 tons. Global rice prices also fluctuated, ranging from Rp. 6,674/kg in 2019 to Rp. 8,667/kg in 2023. Crop damage was lowest in 2022 at 470,131 hectares and highest in 2019 at 819,444 hectares. It's important to note that the fluctuations in rice prices are intensely influenced by several factors that highlight the need for effective price stabilization policies to guarantee the accessibility and affordability of rice for the public.

Organic fertilizer is very important in efforts to improve soil fertility naturally and safely, in the broadest sense of being free from chemicals that are harmful to human health, therefore this organic fertilizer is very safe for consumption. This research was carried out in a housing complex on Jl. Tombak, Medan Tembung District, Medan City, North Sumatra. The research method used in this research is the experimental and observation method. The aim of this research is to determine the content of organic fertilizer made from mixed waste of onion skins and garlic skins with used rice water washing. And the results of the research that has been carried out show that the organic fertilizer that the researchers made failed due to several factors, such as perhaps there being onion skins that had rotted and should not be used and also the fermentation process time was too long, so it did not meet the required standards. Apart from that, when filtering to remove onion skin waste, the liquid fertilizer the researchers made smelled pungent and rotten.

The Bolotomo cattle breeder group in Wingkosigromulyo Village, Nkombol District, Purworejo Regency, has been established since 2010 with the help of subsidies from the local Livestock Service. Initially, they focused on producing organic fertilizer, but switched to the feeder cattle and meat business because the selling price of fertilizer was low. Livestock management is still traditional, and concentrate feed is rarely used because it is expensive and difficult to obtain. In the dry season, food availability is limited, and rice straw and field grass are the main food sources. The service activity by Tidar University students aims to help farmer groups overcome the feed crisis with technology for making pellets from local materials. Demonstration of making pellets using a mixture of calliandra leaf flour, rice bran, pineapple peel, molasses and tapioca flour. Pellets have the advantage of improving feed quality, consumption efficiency and shelf life. Farmers also shared their experiences and expressed the need for processing livestock waste, such as biogas plants, to reduce pollution and increase income. Integration between the agriculture, fisheries and livestock sectors is the focus for sustainable development.
