The Potency of the Rice Crop Index Development through Adjustment of Agroclimate and Water Management Situated in Rainfed Field Gunungkidul

Abstract

One of the strategies to increase the rice self-sufficiency is by improving the rice crop index (IP) in rainfed field areas. This paper aims to obtain the areas for IP development based on agroclimate information on the rainfed fields in Gunungkidul. The methodology of research was based on descriptive analysis, surveys and interviews involving farmers, researchers, agricultural officers, and village officials. We performed field surveys and interviews in 2016 and 2017. The surveys were carried out by identification and verification of the water sources for agriculture, determination of the appropriate water infrastructure, and determination of the areas affected by rice cultivation development. The results showed that the determination of the beginning of planting season could refer the Modern Integrated Planting Calendar (KATAM) and the estimation of the start of the rainy season by the local meteorological office (BMKG). We estimated that as many of 2,111 ha was suitable for IP 200 development, which may raise the potency of rice production to 10,058 tons (increased by 5.10%). On other hand, the IP 300 only covers the rainfed field areas of 687 ha, which has a potential rice production of 3,294 tons (increased by 1.67%). Further identification and verification are needed regarding the potency of water sources. This will determine which types of proper water infrastructure that must be provided for support the development of IP, hence the national rice self-sufficiency.

A Conceptual Model for Development of Small Farm Management Information System: A Case of Indonesian Smallholder Chili Farmers

“…Several earlier studies focused on certain aspects of the FMIS ecosystem. For example, some studies focus on monitoring plant growth [33], climate and planting calendars [34], water management [35], the use of drones [36], and related product marketing [37]. In addition, there is no mobile application (Android) that offers the use of FMIS as an agribusiness ecosystem.…”

“…Providing farmers with advanced tools and knowledge to implement sustainable production is one of the essential efforts to mitigate the impacts of climate change on the agricultural sector. Several actions to achieve this effort is by providing droughttolerant varieties (Loboguerrero et al, 2019;Mottaleb et al, 2017;Perdinan et al, 2008;Yasin and Ma'shum, 2006), high-temperature tolerant varieties (Killi et al, 2017), and saline tolerant varieties (Thi Nhung et al, 2019); improving forestry agriculture (Shrestha et al, 2018); enriching biodiversity (Thierfelder et al, 2017); optimizing the efficient use of rainwater (Setiapermas and Jauhari, 2008;Srihartanto and Widodo, 2020;Velasco-Muñoz et al, 2019); replenishing groundwater with conservation agriculture (Lillo et al, 2019); developing marine defense systems (Koh and Teh, 2020); and better floods management in situations of sea-level rise and storm surges (Lilai et al, 2016). All these actions are beneficial to improve mitigation of the impacts of current extreme climate variability, as well as countering the adverse effects of climate change in the future (Bruinsma, 2003).…”
