Currently, proven oil reserves in Indonesia is about 2.483,97 MMSTB in 2019. Assuming a constant production without the discovery of new reserves, then in the next 10 to 11 years Indonesia will not be able to produce petroleum anymore. On the other hand, compared to proven petroleum reserves in Indonesia, proven natural gas reserves in Indonesia are quite large. It is around 49,74 TSCF in 2019. And the reserve to production is about 34 years since 2009 to 2018. Therefore, in this work, a syngas to synfuel plant has been prepared as a contribution for preparation of a shifting from producing fuel with petroleum as raw material, to fuel with natural gas as raw material. Particularly for eastern Indonesia, where access to several areas is difficult to reach so that the distribution of gas products is less relevant.

Actually, electric power transmission line grid systems in Indonesia with a voltage rating 500 kV has been applied, but only in Java island with Overhead Line transmission line model, and it^s a backbone of the Java-Bali power grid system. Currently, PLN have a Jakarta Looping transmission system project 500 kV Extra High Voltage. This project has a potential delays due to land problems and social constraints along the route. Given that Jakarta is a capital city with a very high population, the construction of a tower transmission line will be a special challenge to complete the transmission project, where the process of land acquisition and compensation costs under along the route (ROW) will also be a special thing. In this research, we will try to estimate the construction cost for the 500 KV Underground Cable as an alternative to the project for other types of aerial cables. The route length will be adjusted into 4 categories of the overhead line route 1)a half of the overhead line route, 2)same with the overhead line, 3) 1.5 times of overhead line, and last 4) 2 times of overhead line. From the estimated calculations with these 4 categories, It is obtained the ratio of construction costs with underground cable designs to the overhead line design is smaller than cost of ratio for the same project design in Europe and/or America. It^s feasible to execute in urban area like Jakarta, Surabaya and Bandung, but not feasible for outside urban area Keywords: Overhead line- Underground cable- 500 kV- Construction Cost- Ratio Share Link | Plain Format | Corresponding Author (Edy Roy Antonius S)

Population Dynamics of Loligo sp in the Waters of the Island of Ternate Umar Tangke1) 1)Universitas Muhammadiyah Maluku Utara, Jl. KH. A. Dahlan No. 100, Kel. Sasa, Kec. Ternate Selatan, Terntae-Maluku Utara, Indonesia, E-mail : umbakhaka[at]gmail.com Abstract Abstract Loligo sp is a group of cephalopods or mollusks that live in the sea, with a horizontal distribution area from the coast to the open sea and a vertical spread from the surface to a depth of several thousand meters in the water column. Until now, the production of squid is still dependent on natural stocks because there has been no study on technology in cultivating it, so there is a concern that if the increased production continues to threaten the sustainability of these resources. Therefore, in the interest of sustainable management, it is necessary to assess the parameters of the population and biomass of the squid resource through analysis of population dynamics including age, growth and mortality and yield per recruit. This research was conducted for 3 months from June to August 2019 with the aim of analyzing the parameters of the population of squid resources and the level of exploitation in the waters of Ternate Island using survey methods and stock assessment and population analysis. The results showed that the squid resources landed in the Hygienic Market in Ternate City had stable growth parameters including the maximum length (L&#8734-) 97.13 mm, growth coefficient (K) 0.23 per month, t0 1.26. The total mortality, natural, and catch mortality values were 0.74, 0.50, 0.24 and the level of exploitation was 0.32, respectively, where this value indicates that the exploitation rate is smaller than the estimated utilization value of 46.0%.

DIGITAL SECTOR INNOVATION TO SUPPORT LESS CONTACT ECONOMY IN INDONESIA Yuda Syahidin Information Technology faculty,Information System Department, Piksi Ganesha Polytechnic Gatot Subroto Street No 301, Bandung Abstract It is predicted that the Corona virus will not pass quickly from the world. The Indonesian government is currently preparing a way to coexist with the COVID-19 outbreak. Now the government is preparing a way through the preparation of the concept of reducing physical interaction. Then Indonesia is said to be included in the list of 170 countries that will experience a decline in economic growth due to Covid-19, so digital transactions must be a mainstay. Digital businesses use technology to create new value in business models, customer experiences and the internal capabilities that support its core operations. The term includes both digital-only brands and traditional players that are transforming their businesses . When face-to-face activities are difficult to do like today, digital technology is the only solution that is able to force business people to try this technology. From this research will produce digital sector innovations that produce several technology platforms in this new normal, namely Logistics and Supply Chain, EduTech, FinTech, AgriTech, HealthTech, SecurityTech. So with the hope that the digital sector is encouraged to be able to reduce the worst impact of the economy, for example, being a substitute for economic activity that is currently limited and also the retail sector, the service sector that is directly affected in the midst of the Covid-19 outbreak. in the future is less contact economy. Innovation in the digital sector is increasingly needed to fill the diminishing face-to-face activities.

Abstract The Patients of artificial hip joint are recommended to limit the extreme movements that could cause damage of the device, such as salat movement. As many study performed the simulation by neglecting the presence of synovial fluid, in this study we examined the performance of artificial hip joint under elastohydrodynamic boundary condition which close to realistic state. To investigated the effect of the existence of the lubricant in the artificial hip joint on the lubrication performance including the structure of artificial hip joint during sitting (^Iftirasy^) salat movement. Fluid-Structure Interaction (FSI) method employed to solve the mechanism of elastohydrodynamic lubrication in the artificial hip joint durining sitting (^Iftirasy^) in salat movements are of particular interest. The simulation results show that in order to obtain more accurate result, the lubricant of the synovial fluid should be considered and modeled, additionally, the existence of the lubricant is proven to prevent the solid contact as well as impingement between the component during sitting (^Iftirasy^) salat movement. In this study we investigated the lubrication and structural performance of artificial hip joint in salat activity to accommodate the major religious practice of Muslim community. The impact of this study are useful in continuing development of biotribology and biomedical aspect of the device.
