Abstract

The implementation of Lean Manufacturing (LM) concept was first performed at automotive industries. It is not easy being lean. Lean manufacturing concept implementation will not succeed at the first time. There were things that may have prevented the implementation meeting the objective is considered as risk. It necessary to maintain the risk of LM concept. This research will show the way for managing risk of LM implementation by Delphi and House of Risk method. This research was team up with aerospace industry in Indonesia who has been implementing LM concept. In this research, 19 risks have been identified. The rank of risk agent has been determined.

Abstract

Several previous studies explained that the implementation of an integrated information system needed to be realized at Perum BULOG because the old system has not been integrated. This was also realized by the management of Perum BULOG by carrying out one of its long-term plans, namely carrying out the implementation of ERP system in 2020. On the other hand, ERP is a complex system because ERP systems often adds more difficulties to the implementation process. Therefore, it is necessary to conduct research on the analysis of ERP implementation at Perum BULOG to see how ERP users will accept this technology using the extended TAM 3 approach. Outer Model and Inner Model are used to test and analyze data from research instruments using the SMART PLS 3.0. Based on the research findings, it can be seen from 12 research hypotheses, 9 research hypotheses were accepted and 3 were rejected. It is known that perceived usefulness is found only factor in system- technology ERP and perceived ease of use which have a positive and significant correlation. Meanwhile, the perceived ease of use factor was found only the organization process characteristic and system-technology ERP factor that had a positive and significant correlation. Furthermore, the attitude factor of ERP user is influenced by the perceived usefulness and perceived ease of use. Where the ERP user attitude factor is able to encourage behavioral intention and have implication for use and user satisfaction.

Abstract

In Indonesia, information and communication technology (ICT) is one of the most crucial economy accelerators, for every 10% increase in the ICT investment, the nation’s GDP grows as much as 1.87%. However, the use of ICT leaves adverse impacts on the environment, particularly carbon emission and toxic waste. This phenomenon has led to the proliferation of the topic of environmental sustainability, one of which is green information technology (GIT). GIT is defined as the utilization of ICT that can directly or indirectly reduce the adverse impact of business processes on the environment. This paper aims to evaluate GIT research to attain a better understanding of the field of GIT in Indonesia through a literature review. Published papers are categorized and a gap analysis is presented to reveal areas that need to be explored more. The results of this study potentially serve as a guide for future studies in GIT, particularly in Indonesia. This research finds that the topic has gained popularity in recent years. There are various research themes under the topic of GIT in Indonesia, with the most explored one being the design and implementation of GIT. The majority of the studies are case-based, limiting the research scope to one particular organization. This leaves broader research objects open to be explored more.

Abstract

National fish consumption is increasing every year, both sea fish and fish farming. That is because the appeal and invitation of the government to consume fresh fish (white meat) which contains lots of vitamins and protein. Milkfish is one of the most consumed fish species because it is easy to get and the price is relatively cheap. One of the biggest milkfish producers in East Java is located in Gresik Regency. The fulfillment of milkfish consumption needs depends on its productivity. Milkfish productivity depends on the area of the pond. The greater the land area, the more milk fish can be produced. However, milkfish farming is often constrained by the size of ponds, so the amount of milkfish harvest is also limited. In this study, the goal programming method is used to obtain several objectives, namely maximizing profits, minimizing capital, minimizing production costs and inventory costs, taking into account the changing demands in each harvest period, population density, milkfish survival rate and growth rate. The profit from selling the harvest can be optimized by selling some fish (on demand) and re-raising the remaining milk fish from the harvest (inventory) for resale in the next harvest period. Although production costs and inventory costs increase with more food, these benefits will be maximized compared to selling the entire harvest during that period. Because the greater the weight of milk fish, the higher the selling price. So the benefits will be far more leverage.

Abstract

PT X, a power generation company, hasn’t been able to meet their target in the business development segment over the past few years. This is due to a problem detected in their Project Portfolio Management, in which PT X’s project selection method hasn’t considered the ambiguity nature of project’s information and risks. This study is going to develop a project selection method for PT X using MCDM (multi criteria decision making) with BOCR (benefit, opportunity, cost, risk) Concept to evaluate many criteria that need to be considered by the company, especially conflicting criteria such as benefit with cost and opportunity with risk. Not only that, hesitant fuzzy will be used because project itself has many uncertain or ambiguous information, so stakeholder will face difficulties in determining the value for the evaluation. From the integration of those things in this study, it is found that for PT X, Benefit has the biggest priority, followed by Opportunity, Risk, and Cost in Project Selection for PT X. It is also found that based on additive-BOCR, Project C gives the optimal value for PT X, followed by Project B, Project A, Project D, dan Project E.

Abstract

A proper maintenance project selection is a key to support performance of power plant. The issue of maintenance is allocation a limited budget to achieve the goals of various maintenance criteria and conflicting objectives. This paper presents an integrated AHP and goal programming. In the first step, since maintenance is measured in qualitative criteria, it is recommended to use AHP to weight and quantify criteria. Second step utilize GP which uses the criteria weights and alternative priorities calculated with AHP to optimize multiple objectives without exceeding available resource constraint. The results show that the approach can aid in selection optimal projects within available budget.

Abstract

This research to analyze the factors that cause risks of low back pain (L5/S1) on Manual Material Handling activities at raw material warehouse and finished goods warehouse. Objective is to determine the factors that cause low back pain (L5/S1), analyze the proposed improvement work system alternative with benefit cost ratio (B/C). The importance of cost-benefits analysis of ergonomics interventions has been emphasized (Tompa et al., 2009; Rivilis et al., 2008). Methodology by observing MMH working system, and distributing job discomfort survey. For the quantitative calculation used RWL, LI and Chaffin’s Model. The model of analysis shows the factor effected to RWL and LI is variable V (vertical distance), D (distance movement), and L (heavy of load). Examples of alternatives proposed : (1) addition of scissor of lift trolleys, (2) addition in amount of workers and (3) modifying of lifting method. Alternative whose the B/C value ≥ 1 are feasible economically to be used. Top management needs a cost-benefit analysis proving the positive outcomes. This economics evaluation showed that ergonomic intervention justifies the costs of the implementation, leading to positive outcomes.
