Published: September 2019

Abstract
Population growth in Tanah Bumbu Regency South Borneo Province is causing increased water demand. To fulfil the water needs, the government provides an alternative water resource by using groundwater as a source of fresh water. The objective of this research is to delineate the groundwater recharge zone. The methods were hydrogeological mapping and spatial analysis approach to delineate the groundwater recharge zone. There were six parameters applied in the research, i.e. hydraulic conductivity, rainfall, slope, soil cover, water table depth, and electrical conductivity. The varies of hydraulic conductivity are 45 m/day (sandstone), 0.94 m/day (limestone), 0.49 m/day (alluvium) and 0.2 m/day (serpentinite). Rainfall has a range from 2,106 to 2,403 mm/year. There are several types of soil cover which are gravel, sand pebbles and clay sandstones. The slopes are varying from below 5° to 40°. The groundwater depth is varying from below 5 m to 10 m depth. Furthermore, the electrical conductivity of groundwater samples has a value around 14.9-1,477 μS/cm. Overlying all parameters in spatial analysis resulted in the recharge area spread in the north, centre, and northwest of the study area.

Published: September 2019

Abstract
Indonesia is catching up with infrastructure development as a developing country. This is an opportunity for large and small contractors, especially construction services to compete for development projects. In the process, the government held a tender for SMEs participating in government projects. In the government tender process there are many obstacles that can affect SMEs to participate and win the government tender process. One of them is more than 50% of the value of tenders under 2.5 billion rupiahs but it cannot be done by choosing directly so that SMEs become difficult to be involved in the government procurement tender process. In this study we will discuss the factors and constraints that affect construction SMEs to participate in public procurement. Factors and obstacles include two main factors, namely the internal SMEs and external factors from the government. The method used is the Partial Least Square analysis method which is doing descriptive statistical analysis and causal analysis that aims to find out whether the factors that influence and become obstacles for SMEs to participate in public procurement.

Published: September 2019

Abstract
Customer satisfaction can be affected by the quality of service. Based on the results of a preliminary observation, it was found that there were many complaints about quality of service in the “x” sub-district. The aims of this research are to improve quality of service in “x” sub-district with integration of Servqual methods, Kano model, and QFD. In Servqual method, it is assumed that if attributes with low satisfaction score improved, it will improve the consumer satisfaction. However, not all improvement in the attributes of the quality of service will increase the consumer satisfaction. Therefore, the Servqual method will be combined with the Kano method to find the primary attributes to improve according to the relationship to the consumer satisfaction. While QFD is used to determine the priority of improvements. From the research results, there were 14 attributes required to improve and the main priority for improvement is to design official website of “x” sub-district.

Published: September 2019

Abstract
The number of Batik SMEs and internet users today in Indonesia has increased This condition prompted the government to create a program of 8 million SME program to go online in 2019. But, until 2017 only 45% of the total targeted SMEs go online. This condition raises the need to understand the behaviour of SMEs implementing internet technology. The research focuses on UKM Batik and the online marketplace (OM), where batik is a unique commodity of Semarang City and OM is the implementation of emerging internet technology. The factors of OM adoption are adopted from a comprehensive T-O-E Framework. These factors form the basis for agent-based model development. Agent-based models that describe the behaviour of SMEs individually show the results of this study. Only 6 of 20 factors are used in the simulation model. These factors are the level of SME understanding that OM can increase the number of company sales, the level of SME understanding that OM can expand the company’s marketing and sales area, the cost of implementing OM, the hardware readiness of SMEs, the level of courage of SME trying new things and the experience of SMEs in using OM.

Published: September 2019

AbstractThis paper shares an experience of implementing risk management in a public university in Indonesia. The shared experience is focused on the triggers for starting the implementation, the critical first steps, and the strategy or approach utilized in the implementation. One of the remarkable findings is the importance of human resource development as a necessary step in the implementation. Another important approach is the pilot project, i.e., instead of implementing parts of risk management system in all units of the organization, the approach takes a limited number of organization units to implement the whole risk management system. The findings are then internationally compared with reports of risk management implementation in other universities. Several recommendations concerning risk management implementation and topics for future research are provided in the concluding remarks.

Designing of Raw Material Scheduling Supply Multi On Supplier Strategies with Price, Lead time, And Stochastic Demand Variations. Case Study: Electricity Manufacturer
Authors: Amelia P , Ridwan A Y , Santosa B 
Published: September 2019

Abstract
Raw Materials are one of the important things in manufacture. The availability of these items is very important for the production process to take place. The researcher will research an electricity company. The electricity company produces electricity equipment. The four types of electricity equipment are cartridges, thermocouples, tubular and mica heaters. Some of them have stochastic demand. Each of them has three components of the same raw material and used to make the product. However, the company cannot fulfil the demand because raw materials are not available, so consumers are looking for items elsewhere. This delay occurred because of the delay in sending raw materials, so the company has to wait until the ordered items arrive. This problem is being more complicated by the differences in parameters for each supplier such as price differences and lead time of arrival. Therefore, the company must determine the optimum scheduling and safety time by minimizing inventory costs as a result of Mixed Integer Linear Programming (MILP) being used in resolving these problems.

Authors: Kusmasari W , Yassierli  
Published: September 2019

Abstract
Several previous studies have stated that there are several risk factors that affect musculoskeletal disorders on construction workers. Most of the studies have reported the existence of individual and physical risk factors, but only few studies have focused on psychosocial risk factors. The present study included 45 construction workers of a building construction project. A self-reported measurement questionnaire was used to determine the prevalence of musculoskeletal symptoms. The results showed that shoulder pain was most felt by workers during the last seven days and the last 12 months. Regarding to the prevalence felt during the last seven days, factor of reward was significantly associated with knee pain (OR: 0.09; 95% CI: 0.01-0.99). Regarding to the prevalence felt during the last 12 months, factor of weight was significantly associated with upper back (OR: 1.11; 95% CI: 1.01-1.22) and shoulder (OR: 1.09; 95% CI: 1.00-1.18). Body mass index was significantly associated with upper back (OR: 1.35; 95% CI: 1.01-1.22) and shoulder (OR: 1.31; 95% CI: 1.01-1.71). Results of this study indicated that psychosocial risk factors have significant roles in developing musculoskeletal disorders.

Authors: Widodo E , Sitohang E A G , Vanany I 
Published: September 2019

Abstract
This paper proposes a model to study inventory management for product and service bundles under product-service system (PSS) concept. This bundle is offered to customers under the dual-channel supply chain (DCSC) structure. By PSS concept, it is expected that the products sold will increase, then the products or services that are not selling well can be bundled with goods that sell well, so as to reduce overstock or deadstock in the inventory. In terms of distribution, using the DCSC structure, sales can increase by 20% from the previous one. This research will be conducted by combining the PSS concept in the DCSC distribution structure, in terms of inventory management. Model is developed of inventory cost minimization for DCSC-PSS by considering order quantity as a decision variable. Afterwards, the model will represent two scenarios of game theory for decision making practice DCSC-PSS, Stackelberg Leadership and Vertical Nash. The initial result of the numerical experiment was DCSC’s total inventory cost, Stackelberg Leadership scenario is IDR 556,642,465.40 greater than Vertical Nash, IDR 468,614,127.10. Afterwards, sensitivity analysis based on customer acceptance (ρ) and percentage of PSS (φ). At last, it was concluded that Vertical Nash was better than Stackelberg Leadership for decision making in inventory management

Published: September 2019

Abstract
Social Health Insurance (SHI) in Indonesia is still facing many obstacles, especially the financial aspects from 2014 to 2017 due to the SHI financial losses that has received more attention from the public and the government in Indonesia. Therefore, this study intends to provide financial strategy recommendations that will get a stability revenue over cost. Dynamic system simulation approaches are used to obtain optimal financial strategies that take into account variable costs and income decisions. The parameter of the load variable is medical costs while the income variable is obtained from the participant premium rate factor. The data come from 2016 and 2017 related data to membership, especially PBPU (Participants Not Wage Recipients). Then, the equation used to find the right strategy is Income ≥ Expenditures. In conducting simulations, scenarios are designed to reduce the level of financial losses that occur in SHI. The scenario of this research is a scenario that changes the parameters of premium rates and benefit costs. The combination of medical cost and premium scenarios is a recommendation from the SHI financial strategy because it gets optimal results so that financial SHI does not occur in a losses. In addition, the results of this study can contribute to the resolution of BPJS Health financial problems in Indonesia which continue to experience a losses.

Published: September 2019

Abstract
The purpose of the paper is aiming to improve the medical supply distribution routing. From the empirical data, we examine four major issues which are multiple replenishments, unidentifiable distribution spot, implementation of wrong information in the system, and matching issues. Repetition, delay, and cross-district sequence of delivery cause extra transportation cost. We proposed a clustering approach to improve the efficiency. We group all the points into several clusters, then routing the path. A distribution centre inside the hive-shaped formation can significantly shorten the distance and reduce the time by allocating to the surrounding individual point separately. Lastly, the objective of logistics is to satisfy the requirements of the end consumers with high quality service, as a special and integrated activity, logistics plays a focal position in modern society, routing optimization is the main focus of VRP. The most significant improvement is the distribution distance reduced from 52 km to 29.4 km, 43.46%. The cost improvement in terms of time decreased from 130 minutes to 61 minutes, 53.08%.

Priority Proposal in Selecting Fresh Fruit Bunch Suppliers Using Analytical Hierarchy Process (AHP) and Weighted Scoring Model
Authors: Alfaris M F , Qurtubi  
Published: September 2019

Abstract
This article discusses the proposed priority in selecting suppliers of fresh fruit bunches in a company engaged in agribusiness that produces crude palm oil (CPO). The problem faced by the company is that the FFB Internal plantation has not been able to supply all the needs of the fresh fruit bunch. In addition, the supply of fresh fruit bunches from farmer groups is not sufficient for processing capacity. In order to overcome this problem the company must determine potential suppliers to meet the processing capacity of the plant. To determine potential suppliers is done by selecting suppliers based on the appropriate criteria. In determining suppliers, the analytical hierarchy process (AHP) and weighted scoring models are used. The AHP method is used to determine the weighting of the quality criteria for fresh fruit bunches, then the weighted scoring model is used to rank suppliers based on the results of the questionnaire provided. Based on the results of the AHP calculation, the criteria for the quality of fresh fruit bunches, namely clean loose, have the highest weight of 0.24. Then based on the weighted scoring model, the supplier sequence is B (83), C (83), D (83), H (83), E (83) G (81.5), J (80.5), L (80.5), F (80), E (79), I (78.5), K (78), and A (71.5).

Published: September 2019

Abstract
Based on the study of water hyacinth fibres, the results of tensile tests and compressive flexural tests for water hyacinth fibre composites laminated with methyl methacrylate resin as reinforcing materials for the manufacture of trans femoral socket prosthesis, showed there is no significant difference in strength and flexibility between water hyacinth fibres and nylon glass fibre which is more often using in orthopaedics technology.
Objectives: This study aims to engineer water hyacinth fibre as reinforcing materials for fabricating trans femoral sockets and perform the structural testing.
Study Design: Experimental, bench research.
Result: The availability and renewable natural fibres has the potential to reduce hazards for those involved in manufacturing the artificial limb sockets, without reducing and compromising the strength of sockets and benefiting for the users. Wall thickness, fibre direction and fibre-matrix resin lamination played a significant role in socket strength.
Conclusions: From this limited study we conclude that the resin and water hyacinth fibre composite socket has the potential to replace the standard layup. Further mechanical and biocompatibility testing as well as a full economic analysis is required. Thus, the use of composites with water hyacinth fibres has the potential to be further developed as an alternative material for socket prosthesis in Indonesia.

Published: September 2019

Abstract
The performance of the state-owned enterprises (SOE) in Indonesia seen from the total assets, income, and net income for the period of 2012 to 2016, is still not optimal. Such conditions are related to the formulation of business strategy that are based on capability and leadership style. So this study aims to examine the effect of leadership style and capability on business strategy. This study uses quantitative methods with verification analysis. The unit of analysis is SOEs in Indonesia with the observation unit is the management of the company. Data and information are collected in a cross section / one shoot time horizon. The design of the analysis used to test hypotheses is Partial Least Square (PLS). The results of the study show that leadership style and capability play a role in the formulation of business strategy. Capability has a greater role than leadership style in the formulation of the right business strategy. This results have implications for SOE’s management that the formulation of the right strategy is built by superior capabilities and driven by appropriate leadership styles
