The aluminum powder size’ effect on rice plant fiber reinforced composite to hardness, wear and coefficient of friction of brake lining
Authors: Darmawan A S , Purboputro P I , Febriantoko B W 
Published: January 2020

Abstract
Composite particles are composites that contain particle or powder-shaped reinforcing materials. Particles as reinforcing materials greatly determine the mechanical properties of composites because they carry the load distributed by the matrix. The particle size, shape, and material are factors that influence the mechanical properties of particle composites. The friction component material that is intended for brake lining applications is strongly influenced by the size of the particles and the direction of loading. On the other hand it is necessary to step up the particle size optimization which will affect braking performance, which includes: friction numbers, wear, friction time and friction temperature produced. Therefore this study is aimed at optimizing the particle size against hardness, wear resistance and friction of aluminum powder in rice plant fiber reinforced composite. In this study, the materials used in the experimental process were rice plant fiber, fiberglass, aluminum powder and polyester resin. After the material is processed into the composite, hardness is tested using the durometer shore hardness method, after that, wear and friction testing were conducted. The results show the smaller the size of the aluminum powder, the harder the composite. The smaller the size of aluminum powder, the less wear of the composites. The failure of the adhesive was seen in the specimen tested for wear.

Abstract
This study observes work thoroughness of sorting operators in quality control station at drinking bottle industry. Operators sort the bottles manually using naked eyes to decide whether the bottles have some defects or not. Dirty bottles, cracked, chipped or have water volume that is different from other bottles will be taken by operators. The low light intensity in quality control station causes high numbers of defect bottles to pass the inspection. The standard of Government of Indonesia Health Ministerial Decree No 1405 The Year 2002 that work performed continuously needs 200 lux of lighting. Illuminance level measurement is conducted for five days at 09.00, 11.00, 13.00, and 15.00 o’clock using lux meter on four measurement points using a grid of 1m x 1m. In this study, the average light intensity in quality control station 1 and 2 is 59.30 lux and 52.15 lux. The number of defective products that pass the inspection in a quality control station for 5 days of observation is 2,676 bottles or 55.47% from the total defect products, while the number allowed by the company is only 5%. The correlation between illumination factor in quality control station 1 and defect products that pass the inspection is calculated moment Pearson correlation product and the results are ŷ=292,885-1,317x and r=-0,3147, while in quality control station 2 the results are ŷ=524,077-4,919x and r=-0,6329. The higher illumination level, the lower the number of defective products that pass the inspection, which means operators’ work thoroughness improve.

Published: January 2020

Abstract
This study modifies the economic order quantity (EOQ) model for the problem of allocating refrigerated rack space in retail. The purpose of this study is to obtain the amount of space allocation for each product that can maximize retail profits. In the modified EOQ model, there are three components of storage costs, specifically storage costs, energy costs and quality costs. Energy costs and quality costs are adjusted to the ratio of cooled performance (i.e. Coefficient of Performance) and quality deterioration rate, respectively. This study adapts Water’s algorithm for EOQ orders with constraints on storage space in determining the amount of space allocation for each product. The Water’s algorithm uses an Additional Cost approach that is inherent in each unit of space used. The results show the cooling temperature is an important parameter in determining energy costs and quality costs. Through numerical examples, it is determined the right storage temperature and space allocation which gives maximum profit.

Abstract
The need for rehabilitation robots is increasing, while the current price is too high. One reason for the high price of rehabilitation robots is the complicated controller design. For this reason, there is a need for a simpler controller design to be produced at an affordable price. In this study, the NCTF control system tested its performance on a rehabilitation robot prototype with a horizontal linear motion system. The tests are carried out using point to point and set point tracking commands. Point to point testing is carried out at a distance of 50 mm, 150 mm and 230 mm. Meanwhile, set point tracking testing was carried out on the sinusoidal wave with a 100 mm amplitude and a frequency of 0.25 Hz. Both tests were carried out by giving a load of 0 Kg, 0.82 Kg, and 1.64 Kg. The results of this study indicate that the NCTF control provides a good response. The steady-state error value for all point to point motion commands below 2%. As for set point tracking commands, the system can follow orders properly, but there is a 0.24-second delay.

Abstract
The government of Indonesia has launched a program of ‘Making Indonesia 4.0’ since April 4th 2018. The program is an integrated roadmap to implement a number of strategic action to enter the 4.0 Industrial era. One of the strategic initiatives is the development of functional clothing by producing a cloth that has multifunctional properties, such as antibacterial clothing. Batik, a traditional cloth is originally from Indonesia. It is fabricated by applying hot wax onto a fabric to create a pattern before colouring process which is then removed in the final stage. Since people use batik in daily life for clothing and household appliances, it is worth to produce antibacterial batik. This research aimed to make antibacterial batik by applying zinc oxide (ZnO) nanoparticles to the material of batik i.e. cotton. Colouring process was conducted by synthetic dyes of indigosol. To see the effect of ZnO application, the antibacterial activity, the colour fastness to washing, the colour strength (K/S) and surface morphology of batik have been examined. The results showed that the batik exhibited antibacterial activity due to the incorporation of ZnO onto the fabric. The colour strength was also enhanced. To maintain the colour fastness to washing, the ZnO should be applied to the fabric before the batik process.

Published: January 2020

AbstractCorporate entrepreneurship (CE) consists of three dimensions, which are innovativeness, proactiveness, and risk-taking. It has an essential role in ensuring SMEs willingness to adopt technology in the 4.0 industrial era. The aim of this study is twofold. First, to discover the pattern CE (innovativeness, proactiveness, and risk-taking) intensity on four SMEs and second, to identify the likely causes of that pattern from a strategic management perspective. This research employed a case study design with four Indonesian SMEs as the subjects. The data was gathered through guided interviews and observations. Dyadic data was collected to avoid bias. The answers were then put into a scale from one to seven by the informants and combined using a simple mean. A pattern was inferred from the scale. The results suggest that all four SMEs have a similar low-medium range of CE intensity. From the strategic management standpoint, this was likely due to the fact the SMEs have not conducted proper environmental scanning in terms of looking for new technology or embraced the involvement of low-level employees in their planning process.

Cost and Emission Optimization in Power Plant Using the Single Echelon Economic Dispatch Model (SEED)
Authors: Wahyuda  , Muslimin  , Widodo S U 
Published: January 2020

Abstract
The electricity supply chain system consists of power plants, transmission and distribution. Differences in power plant characteristics cause differences in fuel costs and emissions. Inaccuracies in scheduling the plant have an impact on the surge in fuel use. This becomes the basis for the optimization of power plant scheduling. Optimization on the generator side is usually using the economic dispatch model. However, the Economic Dispatch Model does not consider optimization on the transmission network. Optimization on the transmission network is needed because there are losses in the transmission network. Losses will be even greater when the distance between the power plant and the customer is getting further away. So if distance can be minimized, fuel costs can be reduced. Minimizing the distance for shipping goods can use the transportation model, but the transportation model cannot be used for electricity distribution. This is because there are differences between goods and electricity. Therefore, this study proposes the Single Echelon Economic Dispatch (SEED) model. This model is a combination of the economic dispatch model and the transportation model. This model is able to do simultaneous optimization between the generator side and the transmission side. The model is applied to the Mahakam system in East Kalimantan, using all PLN’s power plants. Load consists of two types, namely low load and peak load. As a result, in peak load and low load conditions, the P11 power plant produces the biggest losses and emissions. This is because electricity production in P11 has to go through a longer path compared to other plants. The P11 is also a power plant that requires the highest fuel costs

Abstract
Increasingly developing technology makes human easier to carry out the life, and one of them is in the transportation sector. The high number of vehicle accidents causes losses to the passenger so that it requires safeguards to minimize these losses, one of the ways is by using a seat belt. This study aims to design a voice of customer-based seat belt using integrating Kano model and Quality Function Deployment (QFD) produced by an innovative product, namely “Multifunctional Seat Belt for Vehicle Safety”. Through the distribution of questionnaires, 8 attributes are needed in the design of the seat belt. The results of the Kano Model analysis show that 2 attributes fall into the indifferent category which is then eliminated because the presence or absence of these attributes does not affect customer satisfaction. The other 6 attributes are portable, can store items, can hold the body while sleeping, can warm the body, there are pads on the sides of the head, and adjustable strap. These attributes are entered into the QFD framework until phase 1 to obtain a priority sequence that is useful in the production process later. In addition, MUSESA is designed with anthropometric approach which is using 5 dimensions so that it is ergonomic for users.

Published: January 2020

Abstract
In inventory management, stockout and overstock are problems that always occur in the inventory system. The limitations of the method make it difficult for companies to determine the level of inventory following probabilistic inventory conditions. Ajeng Gallery is a quality bag craft company that has problems in the supply of raw materials where there is always a large stockout and overstock. The research is limited to cow leather material which is the main material based on the results of ABC analysis. This research also integrates Min-Max method which is a deterministic method to determine the level of inventory then the results will be integrated with Monte Carlo simulation which is a probabilistic method so that it can evaluate the amount of stockout and overstock that occurs. The results showed that the company no longer experienced stockout for 1 month and the amount of overstock decreased by 0.42% of the actual system.

Published: January 2020

Abstract
The increasing of cybercrime means an increase in the number of digital evidences produced in these criminal activities. Also, to pay attention to the security and integrity of digital data, the construction of digital evidence storage must pay attention to the need for convenience in adding storage and the need for investigators to avoid geographical problems in carrying out their duties. An ideal implementation of the problem is the development of network-based digital evidence storage using the Software-Defined Storage to build a clustered storage system. In this study, we build a clustered storage system using Ceph that will be functioned as digital evidence storage. Ceph is a Software-Defined Storage which is designed to provide excellent performance, reliability and scalability. On the other hand, since digital evidence is fragile, then the security of storage system must also be considered so that the stored digital evidence in the storage system can be accepted in court. The security includes aspects of confidentiality, integrity and availability aspects. We were able to build a storage system using Ceph and as a result, our system storage has met the aforementioned scalability, confidentiality, integrity and availability aspects. The storage system is expected to contribute in terms of digital evidence storage and preservations.

Published: January 2020

Abstract
Student participation is a key success in almost every learning process. It is believed that concept-level of understanding could be achieved only if students are actively involved in the learning activities. The concept of student centered and active learning is usually adopted in order to improve student participation. Problem Based Learning is one of popular methods used in this paradigm, in which students learn both thinking strategies and domain knowledge of a subject through the experience of problem solving. In addition to this current well-known learning method, this paper introduces a new approach so called Solution Based Learning in which students learn about a subject by analyzing solutions that has been given by some experts. Basically, the concept urges students to analyze the way of thinking of the experts on why they could give the solution like this and that. Students then may adopt the thought or criticize it in a positive manner. In order to see its viability and applicability, this new concept has been implemented in Product Design and Development Course as a case study. Based on the process performance analysis, it is shown that the proposed approach is able to improve student participation, to make class more active and to improve the overall student understanding of the subject of study
