Farmer adoption of sustainable rice farming technologies and practices is critical for climate change adaptation and mitigation. Often adoption is investigated in isolation focusing on factors influencing farmer decision making and overlooking the effects of technology adoption on farmers’ livelihoods and perceptions of change. Therefore, the present study investigated technology adoption and its effects on farmers with a special focus on additional revenue allocation and perception of social, economic and environmental change. Using a digital survey platform, 153 farmers (21.6% female) were interviewed in three sub-districts of Yogyakarta, Indonesia. On average, farmers adopted two technologies or practices, adopted high-yielding rice varieties, and increased their revenue from US$105 to US$122 per hectare per season. Barriers to adoption included time constraints, unsuitability for field conditions and incompatibility with cropping systems. Farmers invested the extra income in farming business and improved diets. Furthermore, farmers perceived changes in social and human capital and also poverty reduction due to technology adoption. This study highlights the importance of including an analysis of social impact in agricultural research.
In certain location, it is undeniable that there are qualities variations of fermented cocoa beans depend on processing techniques. In addition, its cocoa bean's production central at Yogyakarta have their specific characteristic own regarding the use of fermentation box (box type). The purpose of this research was to analyze the effects of three types of fermentation box and duration to fungi level of fermented cocoa beans. CRD (completely randomized design) with two factors and three replications is applied as assessment method. The first factor is the type of fermentation box (basket, storey box and single box with a hand crank) and the second factor is the length of fermentation time (3 and 5 days). The result of the research explained that the lowest levels of the fungi achieve within 5 days of fermentation processes. Meanwhile, a single box with a hand crank provide the lowest of fungi's level. Furthermore, the combination of those two results may give the most favorably expected condition of fungi level.
There is a challenge to increase the productivity of rain-fed rice in Yogyakarta. However, brown plant hopper and blast disease are the main constraint. Tolerant varieties are suggested due to its environmental friendly to increase rice yield. This research was aimed to determine the population of brown plant hopper and blast disease as the effect of varieties improvement in increasing rain-fed rice productivity. Research was conducted in Nglipar Gunungkidul Yogyakarta, from September 2018 to January 2019. Experimental design was randomized block design with 6 treatments and 4 replications. The treatments were six rain-fed rice varieties (Inpago 8, Inpago 10, Inpago 12, Inpago Unsoed, Rindang 1, and Rindang 2) with two control varieties (Inpari 42 and Ciherang). Results showed that Brown Plant Hopper population and blast disease intensity in Inpago 10, Inpago 12, and Inpago Unsoed were lower than in other varieties. Yield of Inpago 8, Inpago 10, Inpago 12, Inpago Unsoed, Rindang 1, Rindang 2, Inpari 42 and Ciherang were 6.20, 7.37, 7.01, 7.49, 6.20, 6.84, 6.97, and 4.00 ton ha-1, respectively. Varieties improvement resulted higher rice productivity compared to Ciherang as existing variety in farmers practices.
