Published: April 2020

Abstract
The problem in this study is the reduction of local cultural wisdom values, caused by the enormity of the wave power of globalization and technology that have a significant impact on human life in multidimensional dimensions, especially in the cultural dimension. This condition is further exacerbated by the non-optimal role and function of education that has not been able to be oriented towards efforts in giving birth to people who have selfidentities as civilized creatures and understand their role in life as citizens of the world community, so it is not possible that this will bring a freezing effect on cultural values which exists. Therefore, there is a need for preventive and curative efforts to overcome these problems, through the revitalization of education, especially technology-based regional language education. Regional language education, needs to be oriented to use technology as an element of progress in the era of human culture. In addition, this is based on the reality of life today which has been in the era of the industrial revolution 4.0, when life has transformed massively in the digital dimension.

Published: April 2020

Abstract
Diesel engine power plant suffered damage to a number of engine components after being operated a long time before. Damage begins with the sound of harsh sounds and then followed by very large vibrations. With this incident, the operator in charge then performs an emergency stop. Visually it is known that engine components that are damaged include the engine block and cylinder liner broken, broken piston rods, and broken crankcase covers. A number of engine components look out of position. From the visual observations obtained that the damage that occurs in the diesel engine most likely starts from damage that occurs in the piston rod. Therefore, the damage analysis carried out is only aimed at efforts to determine the types and factors that cause damage to the piston rod. A number of laboratory tests have been carried out including analysis of macroscopic examination of fracture surfaces, metallographic tests. From the results of damage analysis obtained shows that damage to the diesel engine piston rod is likely caused by wear that occurs at the small end of the piston rod so that it causes looseness in the bushing and causes enlargement in the gap between the rod eye and bushings. This condition causes a very large increase in stress on the bushing and rod eye so that the bushing is overloaded and in the end can cause damage (crack / break) on the bushing.

Authors: Mastang  , Pahmi M A 
Published: April 2020

Abstract
Overall Equipment Effectiveness (OEE) is a production machine performance measurement system. Performance measurement with OEE consists of three main parameters in the production machine, namely Availability (machine availability time), Performance (number of units produced) and Quality (quality produced). Many OEE monitoring modules are on the market. These modules are still very expensive so most companies are still unable to implement OEE into production machines. In this research, a software called OEEMAX which functions for OEE monitoring has been developed to be installed on Raspberry Pi. OEEMAX was built to be able to run on Raspberry and be able to read inputs from sensors. OEEMAX is also able to communicate with all types of Programmable Logic Control (PLC). The advantage of Raspberry Pi is the price of the module which is very cheap and uses open source operating system. OEEMAX has been successfully developed and applied to Raspberry Pi. It is able to read sensors through general purpose input / output (GPIO) and communicate with PLC using RS-232 protocol. In addition, it is also capable to send OEE data to SQL server.

Authors: Sidabutar D. , Putri E. , Putri N.A. , Sakinah S. , Aryanti P.T.P. 
Published: April 2020

AbstractUltrafiltration (UF) membrane was prepared by blending polyvinyl chloride (PVC) with ZnO nanoparticle (ZnO-Np) and acetone as additives, and then used to treat peat water. The influence of PVC and ZnO-Np concentration on membrane morphology and humic substance rejection were studied. The experimental results showed that the increase of PVC and ZnO-Np concentration in the membrane solution enlarged the pore size of the UF membrane. Agglomeration of particles was found when 2 wt.% of ZnO-Np was added into the membrane solution. The addition of 10 wt.% of PVC concentration and 1 wt.% of ZnO-Np resulted in peat water flux above 100 Lm−2h−1and average humic substance removal of 61%. When the concentration of PVC and ZnO-Np was increased to 12 and 2 %wt, the humic substance rejection was decreased to 40%. More irreversible fouling occurred in the UF-PVC membrane that prepared by low PVC and high ZnO-NP concentration, which is indicated by the low value of the FRR.

Published: April 2020

Abstract
Peat soil is a type of soil having a low bearing capacity. If the ability to support the load is lower than the weight of the construction that must be borne, there will be a bearing capacity failure. Likewise, uneven compression (differential settlement) will cause structural cracking or tilted construction. Soil improvement is needed for land conditions that have low bearing capacity. The 15 MW Tanjung Selor PLTMG project is located in East Kalimantan Province with an area of 10816.51 m2 with peat soil conditions and high water level. Webcyclone is one of the web based recurring simulation programs used to analyze the productivity of a construction work. Based on the analysis of productivity by using webcyclone, the time required for soil improvement work using geotextile is 6.06 days.

Authors: Wibisono Y Y , Marella S 
Published: April 2020

Abstract
Decision-making in business location selection is a challenging task for companies because it involves multiple alternatives and criteria. Previous studies have investigated this problem using various approaches, and AHP/ANP-based decision-making approach is the most used one due to its capabilities in dealing with the complex problem. Although numerous studies have adopted AHP/ANP approach in determining the business location, but most of them were conducted in the large-scale enterprises and not in the context of culinary business such as cafe. This study is intended for selecting the best business location alternative in the context of small enterprise of culinary industry. We developed a decision-making model based on theories and experiences of the culinary expert to choose the best café location. A total of five major criteria we identified namely location characteristics, demography, competition, physical features, and cost. Each major criterion consists of elements that range from two to five elements. Because there are relationships among elements, therefore we develop a network model, which depicts the criteria, sub criteria, alternatives, and their interactions. We apply ANP by using expert opinion to analyse the importance of each criterion and the rank of each alternative. The final result displays that the competitor strength is the highest importance for small enterprises in selecting the best business location.
