[Title: The Maturity Analysis of Hydrocarbon Source Rock in the Naintupo Formation, Tarakan SubBasin, North Kalimantan Province] The Tarakan Sub-Basin, located in North Kalimantan Province, is estimated to have the hydrocarbon potential of around two billion barrels of oil equivalent (BOE). This study aims to analyze the maturity of the source rock and the hydrocarbon potential in the Naintupo Formation, Tarakan Sub-Basin. The method used in this study is the analysis of Total Organic Carbon (TOC), Vitrinite reflectance (Ro), Hydrogen Index (HI), Tmax, Potential Yield (PY), S1, Oxygen Index (OI), and Oil Production Index (OPI). This research shows that the Naintupo Formation is an effective source rock with TOC between 1.02-5.92 wt.%, HI 52-115 mg HC/gr TOC, Ro 0.62% -1.84%, Tmax 436oC -468oC, S1 0.17-0.32, and OPI 0.15-0.4. The type of hydrocarbon with the greatest potential is natural gas. The largest natural gas potential is in the South Sembakung-1, Tanjung Bimau-1, Sesayap E1, and Tanjung Kramat-1 Wells. This study concludes that the Naintupo Formation has the potential to produce the natural gas in the Tarakan Sub-Basin.

The culinary industry continues to develop every year. One of the phenomena is all you can eat (AYCE) Korean BBQ restaurant. This will cause increasingly intense competition in the restaurant business. The aims of this study are to identify customer needs, to determine the priority of the service attributes, and to provide appropriate suggestions to AYCE Korean BBQ restaurant. The big data analysis using LDA method was applied to determine customer needs based on the Zomato review. The results showed that ten customer needs are identified as Voice of Customer (VOC) for HOQ of the Quality Function Deployment (QFD). The results of the AHP showed that 5 priorities of improvement strategies. The appropriate suggestions for Korean BBQ restaurant are to create a layered control system and customer satisfaction surveys, to implement FIFO and LIFO systems, to check the condition of raw material storage equipment, to improve existing service SOPs, and to provide periodic briefings and training.

Ball and beam system (BBS) is a commonly used model to represent several complex and unstable systems. BBS is underactuated system. It is an ideal model to implement kind of control theory. Most of control design are done using simulation method. This method is not realistic because it is conducted on the ideal situation which implies that the result cannot be directly used to control the real system. Hardware in the loop (HIL) simulation is a method that can be used to solve these problems. The use of real controller makes the design experience more realistic and ready to implement. This paper proposes a design of full state feedback for BBS stabilization using HIL simulator. The contribution of this work is to design state estimator on the BBS setup to estimate position and velocity. The result shows that the proposed control and estimator are successfully implemented. The estimator can estimate the output position with time convergent about 1,32 second. The performance of the system is similar with simulation and real plant implementation. It shows that this method can represent the dynamic response of the system on full state feedback control.

Based on its characteristics, biodiesel has a higher density, viscosity, and acidity level than diesel fuel, so it has a disadvantages in terms of lubricants especially in the long run. The impact, it can decrease the kinematic viscosity of the lubricant, a decrease in the total base number, and the impact by decreased of the engine performance. This research aims to determine the characteristics of lubricants from the use of biodiesel (B20 and B100) related to the kinematic viscosity of lubricants and Total Base Number (TBN). The testing method were used ASTM D2896-15 and ASTM D445-06 standard. The study used two units Kubota RD 65 DI-NB diesel engines with a cylinder volume of 376 cc. The rotary speed of the machine was keep constant at 2200 rpm and were operated for 300 hours non-stop. Moreover, the sampled was carried out every multiple of 100 hours. Based on the research results, the quality of lubricants with B100 fuel is no better than lubricants with B20 fuel. B100-fueled lubricants have kinematic viscosity values at temperatures of 40 °C and 100 °C and has lower TBN values than B20-fueled lubricants.

This study aims to observe the tool deterioration following application of minimum quantity lubrication method (MQL). The designed MQL system is completed with an Arduino controller system which was able to be either manually-controlled or automatically-controlled. The tool used in this study is DCMT 11 insert type. The Taguchi method using the Orthogonal Array L9 design was used to compile the design of experiments with variations in depth of cut, coolant composition, and cooling fluid application methods. Each variable consists of three levels. Tool deterioration evaluated by observing it under an optic microscope from three sides of the tool. There are four levels of tool deterioration. The value of tool deterioration of each tool is the accumulation of each side view. ANOVA analysis found that depth of cut, cutting tool composition and method of applying coolant influence tool deterioration in percentage by 32.69%, 17.30 % and 12.82% respectively. Moreover, the minimum tool deterioration would be achieved when using the parameter combination of depth of cut of 1.6 mm; mixture composition of 3:7; and using the temperature-controlled MQL.
