Rice-fish farming is widely practiced all over the world, but since some areas lack irrigation, diesel pumps are often needed. Solar-powered irrigation systems (SPIS) are considered to be a more sustainable option than traditional pumps, but are more costly to set up, limiting their use to direct rice irrigation. This study intended to integrate solar-powered pumps in the irrigation system and investigate its viability through the following: establish an appropriate motor size, determine solar panel tilt, and compare with traditional irrigation pumping. The system was comprised of a positive displacement-type solar pump, photovoltaic panels, a charge controller, a battery, and an elevated, lined water impounding system for aquaculture. Tilt angles varying between 5 and 10 degrees were tested by measuring the current drawn from the photovoltaic panels. Three motor sizes were used and compared based on flow rate and volume of water pumped per full 100Ah battery, and the effect of the water impounding system along with raising tilapia on the growth of rice was determined. Results revealed that a 200-watt motor pumps the most water per full battery charge, and that the monthly computed panel tilt had the highest harvested energy. Furthermore, solar-powered rice-fish culture gave a higher yield compared to traditional diesel-pump irrigation, and calculations on the system’s economic feasibility show a benefitcost ratio of 1.26 and a payback period of 2.87 years.

Abstract In the current condition in the village, the community is faced with limited agricultural land and the unpromising sustainability of conventional rice businesses, so that agricultural business is less attractive to the community. The solution that can be done by the community is to build a rice-fish farming innovation village. This study aims to analyze rice-fish farming in terms of social and economic aspects and to analyze the factors that influence the success of the rice-fish farming innovation village for food security and community welfare. This research was conducted from October to December 2020 in Samberembe, Candibinangun Village, Sleman District, Special Region of Yogyakarta. The research approach used a mixed-method, with data analysis using business analysis, descriptive analysis, and prospective analysis. The results showed that an integrated rice-farming program can increase farmers’ income up to IDR 35 million per 1,000 m per year and changing the socio-technical at every phase of cultivation. The success of the rice-fish farming innovation village can be realized with the following key factors (1) a good technical irrigation system, (2) a continuous supply of superior fish seeds, (3) strengthening of rice-fish farming innovation technology, and (4) strengthening of pest eradication technology (beaver). This key factor can be considered as a national scale reference for the development of the rice-fish farming innovation village. The implication of the study is to create a superior and sustainable village that can improve community food security and local economy growth.

Rising temperatures and increased frequency of extreme events will have direct and negative impacts on natural resources. Water resources are limited on earth; hence, there is a need to manage the utilization techniques of water. The irrigation system improvement using the wireless network is a solution to accomplish water conservation goal as well as improvement in irrigation practices. Smart farming enhances the capacity of the agricultural systems to support food security. The need for adaptation and the potential for mitigation into sustainable agriculture development strategies can be incorporated into such system. The smart farming system includes different techniques of agricultural practices to conserve different resources including water. Solar powered smart irrigation systems are a part of the smart irrigation system. Smart irrigation system includes temperature, moisture, and humidity sensors system. Different smart irrigation systems which are used all over the world will be discussed in this chapter.

Abstract. Fatimah IN, Iskandar J, Partasasmita R. 2020. Ethnoecology of paddy-fish integrative farming (minapadi) in Lampegan Village, West Java, Indonesia. Biodiversitas 21: 4419-4432. In the past, the traditional paddy-fish integrative farming (minapadi) was predominantly undertaken by rice farmers in West Java, particularly in the water abundant areas. Currently, however, the practice of the rice-fish system has been dramatically reduced due to the Green Revolution programs, including water pollution that may have affected fish farming in paddy fields. Although the rice-fish systems have rarely been practiced in West Java villages, some farmer groups of Lampegan Village, Ibun Sub-district, Bandung District are still practicing the rice-fish farming system. The purpose of this study is to collect and document the traditional ecological knowledge (TEK) of Lampegan Village about the rice-fish system farming managements, including data on various fish species that are widely cultivated in the community, cultural practices of the rice-fish farming management, and benefits of the rice-fish farming system. A combination of qualitative and quantitative methods was used, with an ethnoecological approach. Techniques of data collection, such as observation, semi-structured interviews, or deep interviews, and structured interviews were employed in this study. The results of the study show that the farmers of the rice-fish farming in Lampegan Village, Bandung District own rich and deep knowledge of fish species and practice of the minapadi system. The TEK of the rice-fish farming management system has been inherited from ancestors and is mixed with western scientific knowledge. The rice-fish farming systems have provided some ecological and socio-economic benefits for village people.

The Cost

The agricultural sector needs to make breakthroughs in the design of production systems to improve farmers' income and operation efficiency. One of the ways is to redesign rice production methods by applying a rice-fish farming system. Lamongan has a different system that combines rice cultivation with vannamei shrimp. Due to the limitation of farmers, the efficiency of the system has not yet reached the optimal level. This study describes the rice-fish farming system, identifies the SWOT and generated the grand strategy matrix, and analyzed the profit efficiency using Stochastic Frontier Analysis. The results showed that the strengths and opportunities are more influential, where the position was in the quadrant I; which means it is in a good strategic position. Meanwhile, the input factors which significantly influence profit where the cost of paddy seed, the cost of organic fertilizer, the cost of inorganic fertilizer, the cost of pesticide, and the cost of shrimp feed. The profit efficiency analysis shows that respondents engaged in this system did not efficiently allocate inputs and production cost factors appropriately. The average profit efficiency level was 78.05 percent; it means that there were still opportunities to increase profits from the system by 21.5 percent.
