System of Rice Intensification (SRI) is one of the innovative rice cultivations with the principle of single seed replantation and intermitten irrigation (IWMI, 2007). The experiment was conducted to analyze the macro nutrients, total microbes, and the rice production by combinations of nutrient and pest management in TF and SRI system. This study applied a nested experimental design with two factors. The first factor was the cultivation system that consisted of two levels (TF and SRI), and the second factor was nutrient and pest management consisted of three combination levels (synthetic nutrient and pest management/P1, organic-synthetic nutrient and organic pest management/P2, as well as organic nutrient and pest management/P3). These combinations were nested to TF and SRI. Data were analyzed by ANOVA. It is found that P1 showed the highest growth and production in SRI and TF. The numbers of the height, tillers, total grains and the weight of seed per pot in SRI respectively are 87.33 cm, 22.17 tillers, 1179.50 grains, and 32.17 g, meanwhile in TF respectively are 78.75 cm, 17.50 tillers, 1063.33 grains and 29.00 g. P3 shows the highest content of macro nutrients and total microbes in SRI and TF, respectively the contents of C, N, P and K of P3 in SRI are 6.82 % (very high), 0.31 % (moderate), 155.69 ppm (very high), and 1804.85 ppm (very high), meanwhile in TF respectively are 6.52 % (very high), 0.25 % (moderate), 52.60 ppm (very high), and 530.79 ppm (very high). The total microbe contents of P3 in SRI and TF respectively are 2.7 x 108 CFU/g and 3.7 x 108 CFU/g. It is concluded that both in TF and SRI system (1) P1 shows the highest growth and production and (2) P3 shows the highest content of macro nutrients and total microbes. Furthermore, it is suggested that in the future the rice cultivation system should be done in a wider scale and multiple planting seasons in order to be able to precisely measure the significant difference of the rice cultivation system towards the rice growth and production.","PeriodicalId":207732,"journal":{"name":"ECOTROPHIC : Jurnal Ilmu Lingkungan (Journal of Environmental Science)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129832882","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research is conducted in the settlements and tourism areas outside the BTID tourism area in Serangan Island, Denpasar, on December 2018 until Februari 2019, using qualitative approach is used through indepth interviews to sixteen informans, which have particular roles in natural resource conservation in Serangan Island, Denpasar, which include conservation and utilization of turtles, coral reefs, sea biota, and many types of governance and partnerships in Serangan Island. Result shows that the government and business partnerships were initiated from provision of tourism infrastructure which was developed into wider partnerships with NGOs and communities in the area of turtle conservation, while collaborative governance in the shape of community-based coastal resources management in Serangan Island. Meanwhile, adaptive co-management was developed through devolution of partial responsibility of turtle’s conservation and utilization to local communities through various deals and MoUs. Result also shows that adaptive capacity of Serangan Islanders has developed towards resilience to changes of environmental and socioeconomic conditions. Two recommendations are advised to natural resource managers in Serangan Island. Firstly, robust data collection and supervision systems needs to be developed for governance of turtles, coral reefs, and sea biota. Secondly, social learning through dialogue, reflexions, and evaluation needs to be implemented to reassess the outdated governance practices.","PeriodicalId":207732,"journal":{"name":"ECOTROPHIC : Jurnal Ilmu Lingkungan (Journal of Environmental Science)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130885731","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The surrounding neighborhood can exchange trash into other forms that have economic value. The waste bank that is a model for other waste banks in Indonesia is the Bank Sampah Induk Bantul, which was established in 2008 and has used an online-based waste management system as of 2015. An online-based waste management system is one of the efforts to facilitate the activities of managers and customers of waste bank. However, its use in Bank Sampah Induk Bantul is still limited. Therefore, a preliminary study was conducted to determine the extent to which the online waste management system is used, so that appropriate actions can be taken to increase the use of the online system. This study uses a qualitative approach, namely field observations, semi-structured interviews and informal discussions. The results of this study indicate that the use of online-based waste management systems is not optimal because the online system does not accommodate the activities and problem solving faced by the Waste Bank.
