Comparative analysis of ethylene-induced ripening in climacteric and non-climacteric fruits: implications for post-harvest management
Get PDFBackground: Ethylene gas contained in fruits can increase the respiration rate. Climacteric fruits are those that experience automatic stimulation towards ripening, accompanied by an increase in respiration rate, as seen in bananas. Non-climacteric fruits, such as oranges, do not experience such an increase or change in respiration rate. The rate of fruit ripening is influenced by temperature, storage conditions, and the use of chemical agents to accelerate ripening. The aim of this article is to investigate the effects of closed and open storage environments, as well as the concentration of chemical agents used in the storage process. Methods: This study used bananas and tomatoes, which were placed in both open and closed storage, and stored in pairs. Additionally, the article discusses the concentration of carbide as a chemical agent that triggers the ripening of oranges. Findings: The results show that bananas and tomatoes are climacteric fruits. The storage treatment of bananas indicated that, across all conditions—whether stored in open or closed environments, or stored together with tomatoes—the outcome was the same: the fruits showed signs of deterioration within one week. For tomatoes, it was observed that storing them in a closed environment led to greater longevity compared to other storage methods. The treatment of oranges showed that ripening occurred more rapidly with the application of carbide compared to without its use. Conclusion: Ethylene gas is a crucial factor in the post-harvest management of various fruits and vegetables. Inadequate handling can lead to mechanical damage. In practice, bananas produce the most ethylene gas compared to tomatoes and oranges. Furthermore, bananas can influence the ripening of surrounding fruits. The use of carbide in different concentrations demonstrated that 10 grams of carbide led to faster ripening and yellowing of oranges compared to lower concentrations or the absence of carbide. Novelty/Originality of this article: This study uniquely integrates the analysis of natural and chemically-induced ethylene effects on climacteric and non-climacteric fruits under varied storage conditions, providing novel insights for optimizing post-harvest management across diverse fruit types

Analisis daya dukung lahan pertanian Indonesia pada bonus demografi tahun 2025
Get PDFCurrently, Indonesia is striving to achieve the Sustainable Development Goals (SDGs), one of which is to eradicate hunger. Indonesia faces significant challenges in meeting the food needs of its population. Food needs are influenced by population growth rates and the composition of the population during the demographic bonus expected to occur between 2020-2030 (Casmudi, 2016). The population of Indonesia continues to increase from year to year. Based on projection data from the Central Statistics Agency (BPS) for the period 2010-2025, Indonesia's population continues to increase at a growth rate of 1.7% per year. In 2018, the population of Indonesia was 265,015,300 (BPS, 2018). During the demographic bonus, the proportion of the working-age population is larger than that of children and the elderly. The increasing number of productive age individuals will increase the demand for rice as the staple food of the Indonesian people to fulfill nutritional needs. It is estimated that the population at the peak of the demographic bonus will be 284,829,000 (BPS, 2018) with a working-age composition of 70% (Casmudi, 2016). The increase in population and the composition of the working-age population drive the increased demand for rice. In order to support the success of the 2025 demographic bonus, adequate support is needed. The carrying capacity of agriculture, especially rice cultivation, is analyzed to determine the position of Indonesia's rice agricultural land carrying capacity so that it can be considered in formulating appropriate policies to meet food needs independently. The objective of this research is to analyze the carrying capacity of agricultural land during the demographic bonus, especially in 2025 as the peak demographic period, to determine the status of the carrying capacity of rice agricultural land. Based on the analysis of land carrying capacity in 2025 during the peak demographic bonus, the value of harvested rice land carrying capacity is 2.418, which means that Indonesia is a country that is already self-sufficient in food but has not yet been able to provide decent livelihoods for its population. Efforts that can be made to increase carrying capacity to improve the standard of living include increasing productivity and controlling the conversion of agricultural land to non-agricultural land

Pembangunan pertanian dalam menentukan model pembangunan pertanian di desa Wonolopo
Get PDFModernization is the process of transformation from traditional conditions towards more modern, developed, and prosperous states. This occurs across various aspects of community life, including rural areas. This research was conducted in Wonolopo Village with the aim of understanding its potential, issues, structural transformation, institutional transformation, and technological transfer. The research method utilized was descriptive analytics, gathering data through interviews. The research findings indicate that Wonolopo Village holds potential in the agricultural sector, particularly in rice and sugarcane cultivation. However, the main issue lies in fertilizer availability. Structural transformation occurs with each change of village leadership, while institutional transformation has been relatively limited in the past decade. Technological transfer has occurred, notably in the adoption of tractors in agriculture. Analysis of agricultural development models suggests the need for technological and institutional innovations to maximize Wonolopo Village's potential. The conclusion of this research underscores the importance of developing agricultural development models tailored to the village's conditions and potential, as well as the significance of collaboration with knowledgeable human resources. Recommendations include the necessity for improvement in village potential management and collaboration with more proficient human resources
Model pembangunan pertanian desa palur
Get PDFAgricultural development plays a crucial role in Indonesia's economic growth, particularly because the majority of its population relies on the agricultural sector. However, this sector faces several challenges, such as structural, institutional, and technological issues. To address these challenges, Palur Village, Mojolaban District, Sukoharjo Regency, is the focus of this study. Through descriptive analysis method, primary and secondary data were obtained through interviews, observations, and recordings. Palur Village's potential includes significant agricultural land and productive human resources, but it faces issues of resource allocation and a lack of interest in agriculture. Structural transformation indicates a shift from the agricultural sector to the industrial or service sectors, but with low incomes. Institutional transformation, on one hand, shows continuity in existing institutional functions without major changes, but the success and changes occurring in local financial institutions indicate the need for further transformation. Technology transfer, especially through the use of modern tools and technology in agriculture, has brought positive changes but still faces challenges in adopting innovations. Based on this analysis, the appropriate agricultural development model for Palur Village is The Diffusion Model, which emphasizes education and the dissemination of technology to enhance productivity and address the challenges faced by local farmers. With proper implementation, this model can serve as a foundation for improving welfare and economic growth in Palur Village and similar areas
Analisis dampak alih fungsi lahan subak terhadap kerawanan bencana banjir: (Studi kasus di desa Jatiluwih, kecamatan Penebel, kabupaten Tabanan, provinsi Bali)
Get PDFSubak is a local wisdom in Bali in the form of a socio-cultural agrarian system for the management of rice fields with irrigation or irrigation systems regulated by members of the Subak group. In its management, Subak land tends to experience degradation due to external interventions as tourism interest grows in Bali. The conversion of land to increase tourism facilities in Bali leads to a decrease in the area of rice fields managed with the Subak system. In the research location, namely Jatiluwih Village, Penebel District, Tabanan Regency, land degradation is identified due to the transformation of agricultural land into non-agricultural land such as hotels or homestays and restaurants to support the tourism sector. Previous research recorded the presence of 10 homestay units and restaurants with medium to large land use sizes on the main road in Jatiluwih Village. This number will continue to increase depending on the promotion and continuous tourism interventions, resulting in ongoing land conversions. Based on spatial observations, rice fields with the Subak system in Jatiluwuh Village cover an area of 360 hectares integrated with a river flow along 80 kilometers. The rainfall in Jatiluwih Village falls under the very high category, which is >500mm. This further reinforces the potential for flooding if the existing land is not well managed. So far, there have been no reports of flooding in Jatiluwih Village due to the overflowing of water in the fields caused by long rainy seasons or storms. However, continuous tourism expansion as a result of Subak being designated as one of UNESCO's Intangible Cultural Heritage in 2012, has the potential to further reduce the area of rice fields with the Subak system, which play a role in the infiltration and perforation of water into the soil. Policies related to tourism growth while preserving Subak rice fields in Jatiluwih Village need to be balanced, so that their existence can continue, especially in avoiding rice field degradation and preventing the potential for floods
