Keong mas (Pomaceae canaliculata) merupakan organisme perusak tanaman budidaya dengan tingkat kerugian yang ditimbulkan mencapai 10-40%. Ancaman keong mas tersebut dapat menjadi peluang yang bernilai ekonomis dan ekologis apabila dijadikan pupuk organic cair (POCMAS-Plus). Produk POCMAS-Plus  hasil dari pelatihan dapat dijadikan pendukung pengembangan pertanian berkelanjutan di Subak Lepud Desa Baha dan mengatasi kegagalan pertumbuhan bibit rosella akibat pertumbuhan yang kurang seragam. Tujuan kegiatan memberikan ketrampilan kepada anggota subak dalam pembuatan pupuk organic cair berbahan siput, dan mengaplikasikan POCMAS-Plus pada tanaman rosella pada fase pembibitan. Metode pelaksanaan  terdiri dari 1)  Kegiatan sosialisasi dan pelatihan pemanfaatan  keong mas menjadi pupuk cair. 2) Demonstrasi pembuatan pupuk organik cair dan 3) aplikasi (POCMAS-Plus) pada tanaman Rosella fase pembibitan.  Uji T berpasangan dilakukan untuk mengetahui  perbedaan pertumbuhan bibit rosella antara yang diberi  dan yang tidak diberi POCMAS-Plus terhadap keseragaman tumbuh, panjang akar,  panjang bibit dan jumlah daun.   Hasil pre test menunjukkan bahwa sebagian besar peserta mengetahui yang dimaksud dengan pupuk organik namun hanya setengahnya yang mengetahui bahan-bahan yang dapat digunakan sebagai pupuk organic cair, serta sebagian besar tidak mengetahui tentang proses pembuatan pupuk organic cair   Setelah dilakukan sosialisasi dan praktek pembuatan pupuk organik cair seluruh peserta mengetahui dan mampu membuat pupuk secara mandiri.  Aplikasi POCMAS-Plus mampu meningkatkan pertumbuhan dan keseragaman bibit rosella. Hasil aplikasi menunjukkan bahwa keong mas dan larutan bawang merah dapat dijadikan sebagai bahan utama pembuatan pupuk organik cair agar pertumbuhan dan keseragaman bibit rosella menjadi  lebih baik.

Tourist visits to Pandawa beach in 2017-2018 experienced a very sharp increase reaching 273%. It is necessary to analyse the environment’s carrying capacity as a basis for planning and the right strategy in its management. The purpose of the study was to analyse the environmental carrying capacity of the Pandawa coast, Kutuh Village, Badung Regency and their utilisation strategies for sustainable development. The study examined the physical carrying capacity (PCC), actual carrying capacity (RCC), management capacity (MC), and adequate carrying capacity (ECC). The results showed the current number of actual visitors with an average of 3,727 visitors/day, which is still far below the physical carrying capacity, which is 20,618 visitors/day, while the actual carrying capacity is 18,864 visitors/day. So, the estimated amount visits per month that can be received is as many as 565,927 visitors/month. At the same time, the ECC value of the number of tourist visits can still be optimised by 109 visitors/day. It means that the number of officers currently available is quite capable of serving 3,727 visitors/day. The strategies to optimise the visit are the addition of facilities, tourist attractions, promotions and increasing the role of local communities in environmental preservation.

Green Open Space "RTH" plays a very important role in realizing a sustainable city and has a balance of functions both ecologically and psychologically for urban communities. Green Open Space can be divided into two, namely public green open space and private green open space, but only public green open space can still be controlled directly by the government. The purpose of this study is to identify the availability of public green open space in the city of Denpasar and to formulate strategies and policies for managing public green open space in the city of Denpasar. Data collection techniques were carried out using interviews and questionnaires, qualitative and quantitative descriptive data analysis with SWOT analysis for the use of public green open space, and the Analytical Hierarchy Process (AHP) to determine management strategies and policies. The availability of public green open space in 2011 was recorded at 2,341.48 or 18.32 percent. The availability of public green open space in 2019 was recorded at 1,572,990 ha or 12.49 percent. The difference in 2011 and 2019 was 768,490 Ha or 5.83 percent. The minimum area for public green open space following the 20 percent rule is 1.68 percent (in 2011) and 7.51 percent (in 2019). The implementation of Denpasar Public Green Open Space (RTH) management has not met the standards of the Minister of Home Affairs Regulation Number 1 of 2007 and Minister of Public Works Number 5 of 2008. The strategy for managing Green Open Space is to develop detailed spatial plans, install information boards, enforce laws, and implement incentives disincentives to relevant stakeholders

Population growth and increasing demand for land for urban development have led to the conversion of agricultural land. Land conversion harms the reduction of agricultural areas and indirectly affects food availability, so efforts are needed to preserve it. The study aims to obtain the availability of paddy fields and the conservation strategies. Evaluation of land use change and availability was analyzed by high-resolution SPOT 6/7 satellite imagery data, slope maps, soil type maps, sub-district administrative boundaries maps, raw rice field maps, spatial pattern planning maps, climate data, and criteria for land suitability for food crops. The strategy of conservation of paddy fields based on the wisdom of Subak (Balinese cultural base irrigation system for paddy fields) was analyzed by SWOT. The analysis showed that the converted land areas were 78.5 Ha. The available paddy fields that needed to be conserved were 895.02 Ha, consisting of a moderate suitability class of 556.74 Ha and a very suitable suitability level of 338.28 Ha. The strategy for conservation of paddy fields based on Subak wisdom must be implemented through 1) Developing tourist attractions based on Subak agricultural activities and rituals, 2) Developing a network of cooperation with the government and business people, 3) Implementing strict Subak rules (awig-awig), 4) Encouraging Subak to be more business-oriented through plant diversification that has market prospects.
