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.

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. Observations were carried out on two corn fields, each measuring 1400 m2 with a distance of 1 meter between the two fields. 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%.

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.

This study aims to analyze and compare rice inventory valuation using the FIFO, FEFO, and Average methods in determining the cost of goods sold (COGS) at UD. Rahayu Indah. This study uses a quantitative descriptive approach with a perpetual inventory recording system. Data were collected through observation, interviews, and documentation from January to December 2024. The results show that each method produces different COGS values: the FIFO method produces the lowest COGS, followed by FEFO, while the Average method produces the highest COGS. This difference is influenced by cost allocation based on the order of goods in and out and price fluctuations during the production period. These findings indicate that the FIFO method is the most effective method to be applied at UD. Rahayu Indah because it reflects the logical physical flow of goods, supports cost efficiency, and increases the company's gross profit. In addition, this method is also in line with the company's operational characteristics, which have stable purchasing patterns and are in accordance with the principles of PSAK No. 14 on inventory. The results of this study are expected to assist UD. Rahayu Indah's management in determining an inventory valuation strategy that is efficient, accurate, and supports business sustainability.

Increasing rice production is a national strategic priority given its role in maintaining food security and economic stability in the community. This study aims to analyze strategies for increasing rice production in Indonesia through a literature review approach based on relevant scientific articles. The analysis was conducted to identify the main factors that affect rice productivity and to formulate comprehensive strategies covering aspects of cultivation technology, land and water management, institutions and extension, production risk mitigation, and socioeconomic factors. The results of the study show that modern cultivation technology, especially the use of new superior varieties, the legowo planting system, and balanced fertilization, are the main foundations for increasing productivity. However, the success of technology implementation is largely determined by stable access to water, coordination of farmer institutions, intensive extension support, and the availability of capital and supporting infrastructure. Production risks due to climate change and pest attacks also have a significant impact on yield stability, requiring integrated mitigation strategies such as simultaneous planting and strengthening of integrated pest management (IPM). Overall, this study confirms that rice production enhancement strategies must be integrative, adaptive, and sustainable by strengthening the synergy between technology, institutions, and supporting policies. These findings are expected to serve as a basis for formulating more effective agricultural policies to boost national rice production.

This research program aimed to improve farmers’ understanding of the Jajar Legowo rice planting system and to analyze the factors influencing their perceptions. The program was conducted with the Sukatani Farmer Group in Tukdana Village, Indramayu Regency, using a mixed-method approach that combined observation, interviews, and questionnaires with 30 farmers. The results showed that farmers’ knowledge of the Jajar Legowo system was relatively low (54.17%), while their attitude was in the moderate category (58.92%). Correlation analysis revealed a strong relationship between knowledge and attitude (r = 0.672), which together shaped farmers’ perceptions of the system. Further analysis indicated that only land area had a significant influence on farmers’ perceptions, while age and education level showed no significant effect. Qualitative findings also revealed that farmers’ perceptions were influenced by direct farming experience, agricultural extension activities, institutional support, and social influence from leading farmers. Based on these findings, efforts to increase the adoption of the Jajar Legowo planting system require participatory extension strategies, hands-on demonstrations, and strengthened farmer group involvement.

The early growth of Coffea arabica seedlings is highly influenced by the quality of the growing medium and nutrient uptake efficiency during the nursery phase. This study aimed to evaluate the effect of local-material-based growing media formulations and arbuscular mycorrhizal fungi (AMF) inoculation on the vegetative growth of C. arabica Lini S 795 seedlings. The experiment was conducted using a completely randomized design (CRD) with eight treatments involving combinations of soil, rice husk, fermented manure, and Glomus sp. mycorrhiza, each replicated three times. Observed parameters included plant height, leaf number, root length, root dry weight, and shoot dry weight. Results showed that the combination of soil, rice husk, manure, and mycorrhiza significantly enhanced all growth parameters compared to the control. The synergistic interaction between local organic components and biological agents improved the physical, chemical, and biological properties of the growing media, thereby optimizing root and shoot development. These findings suggest that integrating locally available organic materials with mycorrhizal inoculants offers an effective, eco-friendly, and sustainable approach to coffee seedling cultivation, with high potential for broader field-scale application.
