Farming is nowadays intensively developed in urban areas. Home-garden has excellent potential in supporting household food sufficiency and providing aesthetic value for the household economy. This study's objectives are: (1) to estimate home-garden farming's contribution to household income and (2) to determine the Sustainability of home-garden farming in Yogyakarta City. The research was carried out in the city center and fringe area covering seven districts of Yogyakarta City. The sample was 113 households that utilized their home-garden for farming as the members of farmer groups. Data were analyzed using a simple statistical calculation to determine the contribution of home-garden farming income. Farming sustainability data were categorized into ecological, economic, and social dimensions using a Likert scale. The results of the study showed that the contribution of home-garden farming to household income was 0.81%. This value is relatively small because the land is very narrow. Also, the primary purpose is not for sale. Home-garden farming, both in the city centre and in the suburbs, has a high level of Sustainability, which is indicated by the economic dimension (79.11%), the ecological dimension (78.71%), and the social dimension (84.12%).

Pasuruan has abundant natural resource potential. One of them is Salak fruit commodity. Pasuruan fruit is cultivated by many people in Gondangwetan subdistrict. With the area of plantation that initially reached 22 hectares, it is no wonder if the productivity level of the crop is quite high, namely reaching 7.3 tons in a single harvest. The problem faced by farmers fruit Salak in Pasuruan is the price of Salak fruit fluctuating and lack of skills and knowledge in processing Salak fruit into a product of high economical value. The purpose of this community service activities is to improve the knowledge and processing skills of Salak, increase the economic value of Salak fruit, and participants are able to choose the packaging and packing products processed salak properly. The method used to achieve the objectives is by counseling or lecture, training or practice of Salak fruit production and continued by packing and labeling of products. The results of the participants ' practice of jam, syrup and salak juice in general are appropriate and meet the criteria of the product set, worthy to be consumed and marketed. This activity will provide long-term benefits for the farmers if the community and wisdom holders in Brambang Village continue to provide support to the trainees to improve innovation and creativity in the processing, packaging and marketing of products.

Agroindustri tape singkong adalah  agroindustri unggulan yang mempunyai peran dalam peningkatan pendapatan masyarakat  di kabupaten Pasuruan. Agroindustri tape singkong adalah usaha  pengolahan singkong melalui proses fermentasi menjadi tape singkong. Tujuan dari riset  ini adalah guna mendapatkan kelayakan usaha agroindustri tape singkong di desa Candibinangun kecamatan Sukorejo kabupaten Pasuruan. Sistem riset  yang digunakan metode deskriptif dan teknik pengumpulan data digunakan dengan cara sensus. Analisis kelayakan usaha yang dikaji yaitu, harga pokok penjualan,  biaya investasi dan produksi, juga kriteria kelayakan  usaha antara lain R/C Ratio  , PBP, dan NPV. Perhitungan yang diperoleh adalah R/C Ratio setara 1.6 nilainya lebih besar dari 1, PBP 1 tahun 7 bulan tidak melebihi periode yang direncanakan, NPV Rp. 52.568.847 bernilai positif > 0 dan akan tercapai BEP jika produksi sebesar 28.462 Kg dan harga produk Rp. 6.325. Berdasarkanperhitungan analisis kelayakan tersebut dapat disimpulkan agroindustri tape singkong layak dijalankan.

Geothermal plant produces numerous kinds of possible side products. One of them is silica as a consequence of the existing silica scaling problem which causes geothermal power plant efficiency depletion. The silica recovery possesses a way to utilize it. Geopolymer concrete is a solution to utilize the abundance recovered geothermal silica with low energy consumption and green house gas emission. Thus, in this study, the geopolymerization of geothermal silica and kaolinite will be observed. Geopolymer was inorganic polymer consist of Si and Al atoms that formed through polymerization process. The raw materials being used are geothermal silica as amorphous silica source and kaolinite as alumina source, whereas the activator composed of sodium hydroxide and sodium silicate. Geothermal silica possesses amorphous structure which had been proven by X-Ray Diffraction (XRD) and X-Ray Fluorescence (XRF) analysis with 96.09% silica (SiO2) content and 18.92% alumina (Al2O3) content of kaolinite. The experiment conducted to determine geopolymerization rate of geothermal silica and kaolinite reaction in presence of alkali activator with certain composition and temperature variation ranged from 80°C up to 120°C. Study on geopolymerization rate was carried out by observing geopolymer bond along with the compressive strength as a function of curing time and temperature. As for geopolymer bonds for each sample with different curing temperatures, FTIR and SEM analysis were used to investigate.

<p>Ischemic Heart Disease (IHD) is one of the leading causes of morbidity and mortality in many countries, including Indonesia. Therefore, cardiovascular risk-prediction models are required in clinical practice for early detection in high-risk populations, including the worker population. This study intends to develop a predictive risk measure for early detection of IHD incidences among employees in Jakarta, Indonesia. Source of data was the database of 4,100 medical check-up (MCU) results of employees and entrepreneurs in Jakarta and surrounding areas in January to October 2019. Multivariate analysis showed that being aged &gt;40 years (p=0.000; OR=5.329 (95% CI 2.621-10.833)), having a history of dyspnea (p=0.000; OR=5.699 (95% CI 2.524-12.871)), smoking (p=0.048; OR=2.007 (95% CI 1.924-4.359)) and HDL&lt;50 mg/dL (p=0.049; OR=1.811 (95% CI 1.099-3.281)) were all good predictors to detect IHD in the worker population. The combination of these predictors results with a cut-off point of 2.5, showed accuracy (79.2% sensitivity and 66.3% specificity). Workers who have a score &gt;2.5 are at high risk of developing IHD in the future. This scoring system can be used by workers or companies to take early preventive measures.</p>
