Published: December 2020

Abstract
Passenger presence does affect car driver performance while driving. However, a different type of conversation between driver and passenger might bring different effects on the performance. This car driver’s performance can be measured by the level of sleepiness and the number of accidents experienced by the driver while driving. The level of sleepiness was obtained from the measurement of the driver’s alert level using the Karolinska Sleepiness Scale. Furthermore, the number of accidents was obtained from the measurement of the performance level using the Crash-No Crash indicator. This study applied three experiments on a car simulation, i.e., drive alone, drive with a passive passenger, and drive with an active passenger. Results showed that driving alone experienced the highest level of sleepiness than others while driving with active passengers experienced the highest number of accidents than others.

Published: December 2020

Abstract
Fires often occur due to leakage of the Liquid Petroleum Gas (LPG). Fuels in gaseous forms produce layers due to condensation with a negative effect when evaporated in free air. Fire usually starts with a small spark before inflaming largely. The frequent fires in homes and industrial sites that use LPG gas leads to huge losses of material and life. Therefore, cellular communication technology helps to facilitate the provision of information associated with the fire quickly. Communication is through voice and video calls, as well as via chats using the Telegram application, which provides bot system features from various cellular devices. With the zoning method, each signal sample of the communication is converted and characterized into a data vector with a fast calculation process. The result showed that the input data in the form of captured signals, extracted and processed, produces an output in the form of a warning or notification. Therefore, the application is expected to minimize the occurrence of fires.

As the largest power plant in Indonesia, SPP holds a great responsibility as a supplier 17% of the electricity needs of the Java, Madura and Bali (JAMALI) systems. This makes the SPP also one of the national vital objects (Obvitnas). This paper will calculate the reliability index of the generator using the method of loss of load probability (LOLP) and loss of load expectation (LOLE) based on the value of the force outage rate (FOR). Based on data on failure and daily expenses in 2019, the reliability index of SPP for units 1-4 is 4,23 days per year or 1,23%. The higher values LOLP/LOLE are in 2019 are possibility of SPP has lost its burden for 2 days in a period of 2019 because of force majeure (blackout) which causes a reduced load. To improve power plant is that the electricity load in West Java can be fulfilled with the electricity flow.

Abstract
Food and beverage companies should be able to maintain and measure their performances to survive while the business competition condition is very dynamic. This study was conducted to design a performance measurement system for food production that combines the halal factors in its business process. Halal means authorized, legal, permitted, and allowed to any object or activity that is used or implemented in Islam. Therefore, designing and measure the performance in this study will use the Supply Chain Operation Reference (SCOR) model and Analytical Hierarchy Process (AHP). By using the SCOR model, we will get performance metrics that serve as indicators to observe and maintain the company’s performance. Meanwhile, by using AHP, we will get the importance weight of each metric toward the company’s performance score. The results of this study obtained 15 metrics with 3 halal metrics. The 15 metrics are divided into three performance attributes, which are 5 metrics in the reliability attribute, 9 metrics in the responsiveness attribute, and 1 metric in the cost attribute. The results of the overall performance score is 72.73. Those metrics are useful to maintain and improve the company’s performance.

Published: December 2020

Abstract
Fractionation of lignocellulosic components is a pre-requisite in biorefineries in order to separate the main compositions of raw material for further maximum utilization to biofuels, chemicals, and materials. Generally, a single step process is often insufficient to assure full availability of polymeric sugars from raw material. Therefore, the purpose of this study is to investigate two-step fractionation comprising hydrothermal and organosolv processes for the efficient separation of lignocellulosic biomass with a promising recovered yield in terms of quality and quantity. In this study, the effects of acids and bases concentration were studied in the two-step fractionation process, since they play different important roles in separation process. It was observed that the optimal condition of hydrothermal process was performed at 180°C for 60 min in the presence of 3.3%(w/w) of H2SO4 followed by organosolv process at 200°C for 60 min with 5%(w/w) of NaOH, resulting in the efficiency of hemicellulose and lignin removal of 87.96% and 46.39%, respectively. In addition, the high recovery of hemicellulose as pentose sugars were observed. The remaining cellulose was obtained with 80.22%. These results demonstrated the successive hydrothermal and organosolv process for fractionation of Parawood.

Published: December 2020

Abstract
In this study, the effect of titanium dioxide (TiO2) in poly(butylene adipate-co-terephthalate) was investigated. PBAT/TiO2 biocomposite films containing different weight percentages (0.25, 0.5, 1 and 3 %w/w) of TiO2 were prepared by mixing PBAT and TiO2 in a twin screw extruder and thin films were prepared by cast film extruder. The thickness of each film is in the range of 50-90 micron. PBAT/TiO2 biocomposite films were characterized by Fourier transform infrared spectroscopy, X-Ray diffraction, Tensile testing, Scanning electron microscopy and Differential scanning calorimetry. Incorporating TiO2 (0.25-1 %w/w) in PBAT matrix was found the Young’s modulus and Tensile strength were increased while the addition of TiO2 more than 1 %w/w (3 %w/w) exhibited lower Young’s modulus and Tensile strength as a result of agglomeration of TiO2 that was shown in SEM images. Thermal properties of biocomposite films showed the percent of crystallinity increased by increasing TiO2 concentration up to 1 %w/w. Moreover, addition of TiO2 concentration up to 3 %w/w the percentage of crystallinity was decreased probably as a result of agglomeration of TiO2 that affected on crystallization of PBAT/TiO2 biocomposite films.

Published: December 2020

Abstract
The waste chromium-oxide rods from thermal spray processes contained the valuable components of high chromium. The carbothermic reduction with graphite powders can be used to recover the chromium from the chromium-oxide rod. The waste rods were prepared into small pieces with a half-dimensions of 6.3 mm diameter and 5 mm length, and heated under the reducing atmosphere at 1150 – 1350 °C. Besides, the effect of different types and sizes of reducing agent on the reduction was observed. During the heating and cooling period, argon gas was fed into the atmosphere. Chromium carbide formation was promoted when the temperature and time were increased. Cr-O and Cr-O-Al-Si were observed in the microstructures before and after the reduction. The outermost part of the waste rod can be reduced to chromium because of the interphase zone. Consequently, the carbothermic reduction is one possible recycling method for utilizing ceramic rod wastes from the thermal spray process.
