Rice consumption in Indonesia has risen as the population increasing rapidly. The structure of the young age population will influence the amount of per capita of rice consumption. The rice cultivating and production will also determine whether or not it will fulfil the needs. The present research aimed at analyzing Indonesian rice import within the last decade (2010 – 2019). The research method used was a literature review. The research result shows that within the last 10 years, the width of the rice cultivating and production area have been declining as much as 1,8% and 1.6% respectively. However, the rice productivity rate is still in positive number at 2.0%. Eventhough the household consumption declined as much as 2% annually, apparently this was not enough for Indonesia to fulfil the needs internally. In short term period, an import would be a solution to fulfil the needs for domestic rice consumption. On the other hand, for a longer term, an import can be a problem because the rice trade balance with be disrupted. A small number of rice export volume will result in a rice trade balance deficit in Indonesia.
The conversion of agricultural land to non-agricultural-purposes land had occurred in almost all areas in the Bali Province. This study aimed to explore sustainable food agricultural land control strategies in the Bali Province, by involving stakeholders: farmers, subak institutions, local agricultural board, agricultural business actors, agricultural financial institutions, NGOs, universities, and agricultural research and development bodies as study participants. SWOT analysis and Interpretive Structural Modeling (ISM) are used to analyze study data. The findings showed that the short, medium, and long-term strategies have great potential and are in line with some management policies to control the agricultural land sustainable conversion in the Bali Province. This strategy may bring essential changes for several areas: stimulating agricultural development policy formulation that align with Balinese local wisdom values, leading to a more selective agricultural land investment choice, procurement of special fund for legal protection of staple food agricultural land, and strengthening local to national-scale agricultural institutions.
This research aims to find the spectrum of a park service scope from two city parks in Denpasar, a densely populated city. The city parks in study are Lapangan Puputan Badung and Lapangan Puputan Margarana as city public facilities of Denpasar – Bali that is said to improve citizen quality of life and environment as well. However, this research focuses to see how city parks in Bali serve their users. This study uses a survey research method. Sample of respondents are chosen using accidental sampling technique with questionnaire as media of data collection. Data series include, users’ age, frequency of visit, activities, and domicile. Research findings are analysed spatially and descriptively as well. Result shows that most visitors are young people who spend time mostly for exercising and other recreational activities. It is also interesting to see that both city park users are regular visitors. They visit the parks at least 1 to 2 time per week and spend 1 to 2 hours in there. The parks users mostly come from densely populated areas. That shows the importance of city parks as complement to a city. However, as a city that going to smart city, ICT has not been recognized much. As conclusion, the spectrum of city parks service scope of Denpasar still ranging in traditional functions of public green open space. A city park serves a man-made nature-like place for people to get refresh within an urban landscape setting.
Tanaman Obat Keluarga (Toga) adalah sebidang tanah di halaman rumah yang dimanfaatkan untuk menumbuhkan tumbuhan yang berkhasiat obat untuk memenuhi kebutuhan obat keluarga. Nilai fungsional taman Toga di pekarangan rumah Desa Bukian sudah tercapai namun penataan tamannya belum mempertimbangkan karakter tanaman, estetika serta filosofi Taman Tradisional Bali. Konsep dasar yang diterapkan adalah taman tematik yang menyeimbangkan antara keindahan taman dengan suplay tanaman obat, berdasarkan filosofi taman tradisional bali yang terdiri dari 7 unsur pembentuk taman di Bali. Yang ditonjolkan dari konsep ini adalah tata ruang sebagai alas, atap, dinding dan pola desain di masing-masing mandala yang saling terkait menjadi satu kesatuan sehingga mampu menjadi panduan pemilik rumah dalam menata taman, serta rekomendasi model desain taman Toga hasil dari penempatan tanaman pada konsep ruang yang telah dirancang berdasarkan karakter masing-masing tanaman dan menjadikan filosofi taman tradisional bali sebagai panduan. Dalam setiap perancangan taman di pekarangan diharapkan menggunakan filosofi tamana tradisional bali sebagai dasar sehingga dapat menjaga dan melestarikan kearifan lokal dan menjaga kesehatan keluarga dengan pengobatan herbal.
Puputan Margarana as a city park is used as a public space that can accommodate outdoor activities for its users. Comfort is an important factor consider for users to conduct activity inside. User comfort level can be measured using the thermal humidity index formula based on the temperature and humidity variables. The temperature and humidity can be influenced by the presence of vegetation, especially trees. Differences in tree species composition will cause differences in the canopy density formed. This study aims to identify the effect of the combined tree canopy density on thermal comfort. This research method begins with determining the sample point based on the combination of canopy density to areas that are not shaded by the canopy. Then, the canopy was photographed at the sample point for analysis using Hemiview 2.1 software to obtain the leaf area index (LAI) value. Furthermore, independent samples T test, assessment of thermal comfort, correlation analysis and linear regression between variables. The results of the analysis show that there is a strong correlation between LAI with temperature, humidity, and THI. There were significant differences between THI at sample points 1, 2, 4, and 5 with LAI 1.68-4.53 against THI without canopy shade. Meanwhile, THI at sample points 3 and 6 with LAI 0.96-1.36 was not significantly different from THI without canopy shade. This shows that the combination of tree canopy density in this study has an effect on thermal comfort. This shows that canopy density can be one of the considerations in selecting trees for landscape design for climate engineering purposes.
A reduction in the number of farmers, urbanization, limited land, poverty, environmental changes, uncertainty of production results and limited access to resources are still being serious problems and have a direct effect on farmers' income. Facing that conditions, in order to survive, social networks are one of the adaptation strategies implemented by the farmers. This research aimed to examine the social phenomena of urban farmers in Subak Sembung, Denpasar City and to try to find the rational actions conducted by the farmers in dealing with economic problems that occurred. This research was conducted in March - October 2020. The location of Subak Sembung was chosen because Subak Sembung is a subak that still exists in Denpasar City. The total samples were 20% of the total population, which is 40 people. This research used qualitative and quantitative approaches. The qualitative method in this research was using a case study, while the quantitative method used a survey. The research results showed that social, economic and environmental changes that occurred caused urban farmers to adapt. The adaptation pattern that was implemented was to apply a survival strategy and a double income pattern. The economic condition of urban farmers in Denpasar City was very good. The social network that was formed is a social network to fellow farmers, farmers to management subak, and farm shops. Action rationalism was performed in the context of improving the economy, working relations, and preserving culture.
The studies of the Bulung Boni and Bulung Anggur (Caulerpa spp.) species and secondary metabolites are still very limited. Proper identification will support various aspects, such as cultivation, utilization, and economic interests. Moreover, understanding the secondary metabolites will assist in developing algae-based products. This study aimed to identify these indigenous Caulerpa algae and analyze their bioactive components. The tufA sequence was employed as a molecular marker in DNA barcoding, and its bioactive components were identified using the GC-MS method. The phylogenetic tree was generated in MEGA 11 using the maximum likelihood method, and the robustness of the tree was evaluated using bootstrapping with 1000 replicates. This study revealed that Bulung Boni is strongly connected to Caulerpa cylindracea. However, Bulung Anggur shows no close relationship to other Caulerpa species. GC-MS analysis of ethanolic extracts of Bulung Boni and Bulung Anggur showed the presence of 11 and 13 compounds, respectively. The majority of the compounds found in these algae have been shown to possess biological properties, such as antioxidant, antibacterial, anticancer, anti-inflammation, and antidiabetic. Further study is necessary to compare the data obtained using different molecular markers in DNA barcoding, and to elucidate other undisclosed compounds in these Caulerpa algae.
The social, cultural, economic, and environmental potentials in Subak Sembung are not well-developed, such that these potentials have not been adequately explored by the local community. This study aimed to describe the synergy between subak and the ecotourism in supporting the sustainable national food stability program. Subak Sembung selected as the study location because its location in the middle of Denpasar City and already developed as ecotourism sites. There were 66 participants involved in this study. Formal surveys, rapid appraisal, and map-making through satellite imaging from the Google Earth Pro (GE) application were used to collect the data. Result revealed that the social economy social activities conducted by the farmer were: (1) seed-producing tools, fertilizers, pesticides, agricultural tools, (2) land-tillage, nurseries, cultivating, preserving the plant, harvesting, (3) marketing, and (4) the correlation between farmers, subak and ecotourism; worth to be developed as a tourist attraction site.
