Abstract
One of the right management of the number of resources is through the establishment of an efficient organizational structure in accordance with the conditions of the airport. PT. Angkasa Pura II (Persero) is one of the State-Owned Enterprises engaged in the business of airport services in the western region which currently has 16 airports. With the growing needs of air transportation, PT. Angkasa Pura II is projected by the Ministry of Transportation to become the manager of 21 airports. With an additional projection of 5 airports, PT. Angkasa Pura II (Persero) requires projections for the 21st clustering of airports to be managed in order to form the right organizational structure. Therefore, 5 cluster clusters are formed using the k-means algorithm. This k-means algorithm is used because it is one of the partitional clustering methods. Partitional clustering method was chosen because it was known that the company wanted to form 5 clusters. In this study, clustering was carried out based on variable aircraft movements, passenger movement, cargo, area, terminal area, runway, EBITDA and revenue. The result is obtained in cluster 1 there is 1 airport, cluster 2 there are 6 airports, cluster 3 there are 5 airports, cluster 4 there are 2 airports and cluster 5 there are 5 airports.

Abstract
Due to the TFT LCD manifestation into many related products, this industry has been growing rapidly along with demand increasing. To satisfy the demand, most companies have increased their production capacity and capability by increasing their number of factories in different places and causing complexity in this industry. Therefore, companies are required to optimize their production and distribution system. Thin film transistor–liquid crystal display (TFT LCD) panel manufacturing supply chain can be generally divided into three stages: array, cell, and module processes. Special characteristic of the TFT LCD manufacturing compared with other manufacturing is different capacity unit between its production chains. The capacity unit of array and cell is defined by the number of glass substrate, while the capacity unit of module is represented by the number of panel. TFT LCD manufacturing which is a multi-stage and multi-site supply chain requires high computational for optimizing the production and distribution of their array, cell, and module. This study develops a production and distribution planning model for the multi-stage and multi- site supply chain in TFT LCD industry. Genetic algorithm is proposed in this research to solve the problem. Maximizing capacity utilization and total profit in the supply chain are become the major performance indicator in this model. Experimental results show that the proposed algorithm is performs better than the comparison method. Robustness of the proposed algorithm is successfully justified by numerical experiment and a case study. For time efficiency of the proposed algorithm, parallel – genetic algorithm is designed in this research.

Abstract
Fuel is a main staple consumption of the industry, especially in Indonesia which is an industrial zone. The worlds fuel availability comes from fossils only remaining about seventy years, Indonesia is expected to stay for another fifty years the fuel reserve will be depleted. Fuel utilization in Industrial ERA 4.0 focused more in the supply chain distribution of goods and services, ranging from supply actors to the consumer. Distribution utilizing gasoline-fueled vehicles to transport goods and services, where the role will be increasing in the future. With regard to the phenomenon, It is important to find a New solutions for generating fuel, to support the development activities of goods and services distribution. Gasoline is one of the most common fuel types used, to support the distribution of goods and services. One component of gasoline subtitution is ethanol or methanol that can be produced from pineapple peel, through the fermentation process into a fuel called bio-fuel. In this study will be discussed about the usefulness of pineapple peel, as an alternative to the future shortage of gasoline fuel solutions. The condition is supported with pineapple availability, which placed In the thirteen provinces in Indonesia, With plantation land reaching two million hectares. Analytic Hierarchy Process (AHP) is used to see the skin value of pineapple, that converted into petrol fuel by the public, by observing the culinary dimension of the service, reliability, responsiveness, assurance, empahaty, and tangible. The results of research that took the area in West Java especially Subang regency, show that the community in plantation areas, have not had the awareness of utilizing pineapple as fuel, both for household and industrial activities. The phenomenon is demonstrated by low responsiveness, assurance and emphaty weights, so it is important that people are given a value awareness that can be obtained, of pineapple peels as a value added garbage as an alternative to fuel solutions, to fulfill the needs of household or industrial-making of pineapple dodol, in addition to reducing organic waste derived from the industry dodol pineapple, that available so much in the environment in which they live.

Abstract
The world is facing a fuel crisis because, the reserves of crude oil from fossils are depleting. This phenomenon inspires many parties to find alternatives to non-fossil materials, such as organic material to be converted into fuel. This research discusses of a potential pineapple peel which can produce methanol, as one alternative ingredient that can be processed into gasoline. The main phenomenon of study is determining the location of the establishment of a fuel processing industry, with the raw material of pineapple skin located in an area surrounded by pineapple plantations. Pineapple skin is a waste that has not been exploited, and only becomes organic waste that pollutes the environment. About two hundred thousand tons of pineapple peels per day are produced, so it is a potential raw material that can be converted into gasoline. The delivery of pineapple skins from seven industrial areas that produce pineapple peel needs to be determined, to maintain the logistics continuity that ensures the operation of the industry, pineapple skin processors become gasoline using Gravity Method. The factors observed in this research are distance, road condition, transportation and costs which its weight made by using Analytic Hierarchy Process (AHP), further from the weight was made determinant for the location of the pine apple peels processing industry to be gasoline. Processing results show that the position of the industrial waste processing of pineapple peels, highly determined by economic factors. This phenomenon shows that improving public welfare is more concerned, in seven plantations as well as the pineapple processing industry, compared to distance, transportation selection, as well as road conditions during the time of the pineapple skin waste processing industry was established.

Abstract
In recent years, the basis of customer value has moved from physical product offering to product-service system (PSS). PSS is an integrated bundle of physical products and services which aims at creating customer utility and generating value. Previous studies have proposed several methods for PSS design, but there was little attention given to PSS design considering multi-actor. The PSS provider (manufacturer and service provider) and customer usually have different needs. Therefore, PSS should be designed by incorporating the PSS multi-actors. This research proposes a new model of Multi-actor Fuzzy-Quality Function Deployment for designing of PSS with multi-actor. This model is proposed to collect responses from customer, manufacturer and service provider in designing PSS so as to ensure satisfaction of all parties and conflict of interests could be compromised. In order to support the applicability of the PSS model development, new software is developed. This new methodology has been implemented in a furniture manufacturer in Surabaya, Indonesia.

Abstract
This paper discusses about a company that adopts make-to-order strategy because the company does not have enough fund to provide raw material. The raw material is ordered when the customer order has been received. It occurs a very long customer lead time. due to the production process must wait for the arrival of material. Consequently, the company can not meet the customer order according to the due date, and the company should give a discount of 25 - 30% of the total purchases. This research aim to propose an alternative solution to solve the problem. The customer lead time is reduced by determining a decoupling point, which is placed between the procurement of raw materials and the manufacturing process. The decoupling point denotes a boundary between the make-to-stock strategy in the previous process, and the make-to-order strategy for the process afterwards. The lead time customer, is then considered start from the decoupling point to the due date.

Abstract
Supply chain is a sequence of production processes, include: raw material supply activities (called as inbound logistics), production processes, and distribution activities (called as outbound logistics). Every supply chain activity has risk. Risk mitigation strategy is important because company will be able to identify the right strategy to handle those risks. Companies must be able to predict all risks, both of inbound logistics and outbound logistics. A manufacturing company in Indonesia that produces military and heavy equipment doesn-t have risk mitigation strategy in raw material distribution activity, so this research propose risk mitigation strategies using House of Risk method with Supply Chain Operation Reference (SCOR) models. Identification of supply chain activities involving of company-s plan, source, make, deliver, and return. House of Risk have two phases, first used for identify risk event, risk agent, and determine severity and occurrence value and calculating the Aggregate Risk Potential (ARP), second used for risk mitigation. Research results found there are 35 risk events and 51 risk agents. Based on Pareto principle, there are 24 risk agents have to mitigated, include: error in estimating of production capacity, procurement isn-t based on schedule, defective raw material, etc.

Abstract
Increased sales in the automotive sector every year, forcing supporting companies to support their production activities. Increased productivity, the potential risks also arise that arise and give a negative impact on the company, one of which is rubber industry, as a supporting company. One area that is very vulnerable to risk is the supply chain scope. The complexity of the supply chain structure that involves many parties is very vulnerable to the emergence of potential risks and becomes a challenge in managing them. Therefore, risk management and proactive actions in the supply chain are needed to minimize the losses that will occur. The model that is suitable in overcoming this problem is House of Risk (HOR). The HOR model is divided into two stages. HOR1 is used to identify and rank each identified risk agent. HOR2 is used to prioritize proactive actions that must be applied by companies with selected risk agents at HOR1. In this case, there are 9 proactive actions that are prioritized in overcoming the identified risk agent.

Abstract
Nowadays business competition is getting tougher, especially with regard to meeting consumer needs. Unstable market demand is often a challenge for companies in meeting market demand. Conditions of demand that are often more than inventory or vice versa incur costs that must be borne by the company. The study was conducted at PT. Tri Sapta Jaya which is engaged in the distribution of medical devices, medicines and formula milk. The problem that arises is when the supply is more than demand, the company will have to bear the cost of saving. Meanwhile, when inventory is less than demand, the company must bear the cost of a product backlog. Problem-solving uses a dynamic system approach that has the characteristics of being influenced by time and the existence of interrelationships loop. Causal loop and stock & flow diagrams are used to describe the companys inventory system, then scenarios are carried out to minimize inventory system costs. Two improvement scenarios were carried out, namely the scenario of increasing safety stock and the scenario of reducing lead time. The results obtained from the study are the improvement scenarios chosen are the scenarios of reducing lead time. This scenario can reduce the total cost of the inventory system by Rp. 13,879,099.

Abstract
The new era of Industry 4.0 is marked by, among others, digitalization and automation in every aspects. For banking industry, this era offers a great opportunity by providing technology-based governance tools. This governance technology has changed the way banks operate and offer products and services to their customers by reducing geographical constraints and the costs of financial transactions. Although the importance of technology in the banking industry is widely recognized, concern for the challenges in this digitalization and automation era in the Islamic banking sector is still not well developed. This study is conducted to investigate the factors influencing Islamic bank-s consumers in adopting online internet banking. To test the hypotheses developed, this study uses the extended theory of The Unified Theory of Acceptance and Use of Technology (UTAUT) consisting of expected performance, effort expectations, social influences, facility conditions, and religious factors. This study utilizes 250 Islamic banking customers as the sample, gathered from Bandung and Jakarta. Using Partial Least Square Modelling as the data analysis method, the results reveals that the expected performance and religious factor are the most important determinants for Islamic banking customers to adopt online services. This research extends the existing knowledge of internet banking adoption in the context of Islamic banking. From a practical perspective, this study provides a guidance and strategy for Islamic bank managers to encourage their customers to adopt online internet banking services.

Abstract
The researchs purpose is to analyze the problems in the production process in the occurrence of waste. The method used by the researchers is lean six sigma approach to define, measure, analysis, improve and control (DMAIC). The results of the study were the ability for saus sambal to be at level 3 sigma, while the sambal terasi was at level 4 sigma. The results of the analysis of researchers, in the production process there are two waste. First, waste transportation is in the form of activities to move the labelling table, so the labelling table is placed close to the pallet during the packing process and the second is waste processing in the form of sorting activities and manually re-stripping the raw material in the compounding process. As for the improvements suggested by the researchers, the first is to improve the packing area layout and use conveyors to move the cans to be packed and the second suggestion is to standardize Rpm and the appropriate amount of release rubber to produce optimal fresh raw material peels.

Abstract
The purpose of this paper is to predict the determinants of bank margins (bank-specific as well as macroeconomic condition) in Islamic banks by applying SEM-PLS. Data were collected through financial statements of 11 Islamic banks in Indonesia obtained in each website of bank, covering bank quarter observations for the period of 2013 to the second quarter of 2018. The results show that bank-specific condition has significant effect to the intermediation margin of Islamic banking in Indonesia, while the macroeconomic condition is not significant. This finding improves our understanding on the usage of SEM-PLS to predict the margin intermediation of Islamic banks. This study provides a guidance and strategy for Islamic bank managers to manage their intermediation margin which can affect their customers interest to use Islamic banking services.

Abstract
Frozen tuna is a perishable product that sensitive to temperature changing, therefore a good cold chain system is needed. As a part of the supply chain, Cold chain system aims to maintain the temperature of the product in order to keep its quality from upstream to downstream. There are various problems encounter the cold chain process that effected to the streamline. In consequence, it is important to build a continuous improvement to reduce the risk in the cold chain. The aims of this research are to discover the risk that can be found on the cold chain process, what is the causes, and the connection between both risks and its causes. This matter to develop risk management system on frozen tuna products in Acheh. This research using House of Risk (HOS) method to capture the most critical risk and risk management system is carried out Fuzzy Inference System (FIS) by Mamdani approach. The expected result from this research is an alternative design and recommendation to solve the risk, so that strategy could be applied on the companies.

Abstract
Manual packaging with awkward work postures has a high level of work risk with recommendations for improvement that should be done as soon as possible. Work risks that can be caused by awkward work posture are Musculoskeletal disorder (MSDs). Therefore this study aims to improve the manual packaging work station by designing work tables and chairs based on an ergonomic approach so that it can improve work posture and reduce or even eliminate work risks. The research method used is a quantitative method with a descriptive approach. The results of this study are the design of tables and chairs with sizes obtained from the results of anthropometric measurements of workers. The results of this study imply that workers can do their jobs with good work postures so that work risks can be minimized.

Abstract
The assessment of service quality has received intensive attention over the past few decades. Many tools have been proposed for being used to quantify the level of service quality. SERVQUAL, which divides the term “service quality” into five dimensions (Tangibles, Responsiveness, Reliability, Assurance, and Empathy), is one of the most commonly used tools. However, SERVQUAL is not designed to be instantly implementable in every industry or business sector, but question items belonging to each dimension need to be adjusted to suit their specific characteristics. This study aims to develop the assessment tool, based upon SERVQUAL, particularly for the beverage transportation service. The process started by gathering assessment items from relevant literature. The selected items were modified to suit the beverage logistics industry, and they were then classified into the five dimensions. After that, the validity of the items was confirmed by asking three industry experts to check whether the questions were appropriate and understandable for customers. Next, six experts were asked to provide Item-Objective Congruence (IOC) scores for quantitative validity testing. Subsequently, the adjusted questionnaire was distributed to 29 samples in order to test its reliability, through the Cronbach-s alpha values. The final version of the questionnaire can be used as an effective tool for assessing the quality of service for beverage transportation service providers.

Abstract
Nowadays, the climate change has resulted in extreme weather events. This change happens because of the effect of global warming. One of the main factors is the carbon emissions that have exceeded the permitted limits. Many countries in the world have taken a significant action by making some commitments to fix it. One of the commitments is to give a penalty for the cost of emissions produced by a country or company. In this study, we developed an integration model between inventory and multimodal land transportation by focusing on the costs of emissions produced. To distribute products from several suppliers to several consumers, we proposed train as long distance transportation mode and truck as short distance transportation mode. The purpose of this study is to find the best solution for total system costs. The total cost consists of operational costs and emissions costs. From numerical experiments, the carbon tax rate affects the amount of carbon emissions and the total cost. The trade-off between emissions and costs will produce an optimal solution. In addition, it can be seen the impact of tax to the other decision variables such as inventory and transportation. The method used in finding the optimal condition is Mixed Integer Linear Programming.
