<em>Rice</em><em> </em><em>cultivation</em><em> in the second growing season in dry land at Gunungkidul Special Region of Yogyakarta requires additional irrigation and improvement of physical, chemical and biological soil properties. This study aimed to determine the role of organic fertilizer ameliorant on rice yields during second growing season in dry land. The research was conducted in Sambirejo Watusigar Ngawen Gunungkidul Special Region of Yogyakarta during second growing season from March to July 2019. The study used a Randomized Completely Block Design (RCBD) with 3 treatments in the form of no ameliorant, ameliorant of 2 tons ha<sup>-1</sup> and ameliorant 4 tons ha<sup>-1</sup>, with 5 replications. The results showed that the use of ameliorant 2 tons ha<sup>-1</sup> produced rice 5.64 ton ha<sup>-1</sup> and ameliorant 4 tons ha<sup>-1</sup> produced rice 6.04 ton ha<sup>-1</sup>, which was significantly higher than without ameliorant which only produced 5.29 ton ha<sup>-1</sup> of rice.</em>
Global Challenge Research Fund (GCRF) Blue Communities is a 4 year research and capacity building project for sustainable interactions with marine ecosystems for the benefit of the health, wellbeing, food security and livelihoods of coastal communities in East and South East Asia. Kepulauan Selayar (Selayar Islands), including Taka Bonerate as a Biosphere Reserve and part of the UNESCO’s Man and Biosphere (MAB) Network has been selected as a case study site for the GCRF Blue Communities project in Indonesia. A single case study approach with mixed methods are used to generate knowledge, identify knowledge gap, and triangulate findings. The ongoing research has collated up-to-date knowledge on: (1) current natural resources management strategy in place and what should be adopted in the future and (2) current and projected profile of energy demand-supply. In the next phases of delivery it will inform policy makers and implementers of the mechanisms to optimise sustainable livelihood strategies by: (1) accelerating positive contributions toward sustainable livelihood and (2) mitigating and preventing threats and pressures to sustainable livelihood. Finally it puts forwards strategic recommendations for decision making points which are evidenced-based and holistic, encompassing: (1) best practice policy for sustainable livelihood and (2) community empowerment and programme sustainability.
Marine renewable energy holds strategic potential in Indonesia, not only to meet the target of renewable energy share in the national energy mix but also to provide equal access to clean energy throughout the archipelago. Marine energy in Indonesia is still in the early phase of development, which mainly focusses on resources assessment and power generation through technology prototype testing. Based on a review of available literature, it is found that specific research on the effects of biofouling on material durability of marine energy infrastructure in Indonesia has yet to be addressed. In this study, a matrix that identifies and predicts key fouling organisms and their possible risks on marine renewable energy infrastructure in tropical waters of Indonesia is developed by analysing previous findings in temperate and subtropical waters. Based on the matrix developed, calcareous polychaetes (Serpulidae), barnacles (Amphibalanus spp.), and bivalves (Perna viridis) are among possible key fouling organisms that might pose risks to marine energy infrastructure in Indonesia, such as by adding weight and drag and causing corrosion. Further studies and detailed and statistically robust analysis of the biofouling and its impacts are needed to support the development of the technological performance of marine renewable energy in Indonesia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
