Abstract
The noise level in the stone carving industry center of Sedayu Village, Muntilan District, Magelang Regency is very high. Some workers complained that the ear was disrupted after work and had a disruption in the ear, causing the quality of workers health to decline which had an impact on work comfort and work productivity. Therefore a study was conducted aimed at identifying and describing the health quality of stone carving workers. This research uses descriptive method, with a population of all stone carving workers in Muntilan District. The sample was determined by a purposive sampling method, namely the workers in the stone carving industry center of Sewan, Sedayu Village were 30 people. Health quality is measured by physiological factors which include blood pressure and hearing quality, and psychological aspects are measured from respondents statements on work comfort. The results showed that the profile of respondents consisted of 29 men and 1 woman, with an average age of 42.2 years. The respondent worked every day for 8 hours and on average had worked for 14.4 years. As many as 56.7% never wear Personal Protective Equipment during work and 66.7% have the habit of smoking while working. The results showed that the sources of noise were production machines which included sawing machines, grinding machines, and lathes. The average noise level in the morning was 117.93 db (saws), 110 db (grinding machines), and 111.3 db (lathes). This value is far above the Threshold Value that has been determined in the Keputusan Menteri Tenaga Kerja Nomor 51/Men/1999, which is 85 db for a maximum work time of 8 hours/day. Health quality as measured by blood pressure states that the mean systolic blood pressure is 126.2 and 85.8 for diastolic pressure, while the most hearing quality (43.3%) is in the moderate position of both the left ear and right ear. Furthermore, 86.7% of respondents stated that the work environment was not comfortable. So it can be concluded that the health quality of respondents is still in a safe position, even though the noise level in the work environment exceeds the Threshold Value and the respondent feels uncomfortable at work.

Abstract
Incompatible aid supplies, in which received aid items do not match with the need of the victims, appears to be one of persistent problems in relief operations. The mismatch can be argued due to that the need of aid supplies may vary over time and the nature of disaster creates different need of aid items which are not available in standard survival kit. The purpose of the present paper is therefore to empirically identify aid items that should be available in survival kits by considering time-after-disaster and the nature of disaster. A survey was conducted in Bantul and Sleman districts where earthquake with a magnitude of 6.5 Richter scale and volcanoes eruption have occurred respectively. A total of 120 respondents, consisting 65 respondents from Bantul district and 55 respondents from Sleman (Cangkringan), participated in the study. The respondents were asked to rate the urgency level of the aid items during the first and the second week after disaster. Results indicate the time after disaster, the nature of disaster, and the culture are found to be significant factors influencing the required items of the survival kit. Furthermore, the required aid items during the first week are significantly different than those during the second week after disaster. It is also worth mentioning that the type of disaster determines crucial specific aid items that should be provided in the survival kit.

Abstract
The transportation routing problem is a very popular field in operations research and management science area. Many previous studies are still continuing to develop models and algorithms to produce the best transportation route optimization in various research objects. Technology has enabled the development of the intelligent decision support system (DSS) to optimize transportation route. Although technology has evolved, there are still few studies that build DSS software to minimize transportation distance and fuel consumption, especially using the metaheuristic approach. Thus, this paper aims to develop an intelligent DSS software to minimize fuel consumption and travel distance by considering time windows constraint using metaheuristic approach. The software can receive input dynamically to evaluate and select the best transportation route. The results of this software have been tested using real system data from one of tour and travel company in Indonesia. The company provides travel services using a bus to visit several tourist attractions based on the opening hours of the destinations. Intelligent DSS software output shows that the travel distance is 25.64% more efficient than the current real conditions. In addition, the fuel consumption produced by DSS is better than the actual conditions, which is 17.35% more efficient.

Abstract
In the company, production scheduling is an important step to find out when to start a job and when to stop to end a job. Good scheduling will have a positive impact, namely low operating costs and delivery times which can ultimately increase customer satisfaction. In this study, the focus of the problem was 3 job 5 machines on the production of nuts at PT X. PT X is a manufacturing company specializing in General Contractor - Machining & Recondition Services that uses the FCFS (First Come First Served) system in its scheduling operations. The type of production flow in this company is the job shop because each product goes through a different process in each operation. The problem that often occurs in this company is the accumulation of orders at one time with a large quantity of products and human resources that are still relatively low can be one of the causes of delays in completing orders for customers. The method used in this study is the Non Delay Method and the Heijunka Method. Where, the Non Delay method is a method that does not let the machine idle if an operation can be started. While the Heijunka method is more concerned with equity in its production. In this study, scheduling using the Non Delay Method is better than using the Heijunka Method or using the existing scheduling method used by the company, because it can produce a faster makespan value. With this Non Delay method, to produce 3 Job 5 machines produce makespan of 3772.01 minutes or 62.87 hours smaller than using the Heijunka Method which results in makespan 3820 minutes or 63.67 hours. While the results of existing scheduling makespan only produce 3880.35 minutes or 64.67 hours.

Abstract
The establishment of the ASEAN Economic Community (AEC), which facilitates the movement of goods, services, investments, capital and skills, not only increase trade and investment among member countries, but also promote and expand regional production sharing and network. Companies that look for appropriate places to locate their affiliates can take advantage of this economic integration by cross-border production sharing. Many industries in Thailand can also take an opportunity of fragmenting production processes to other countries, especially to CLMV countries (Cambodia, Laos, Myanmar and Vietnam) since there are several factors contributing these countries to be potential destinations for international production fragmentation. The aim of this paper is to find suitable destination country among CLMV for the production fragmentation of Thai electronics industry. Fuzzy multiple criteria decision-making methodology based on fuzzy TOPSIS (fuzzy technique for order preference by similarity to ideal solution) approach is applied in the selection of the destination country. By considering eighteen criteria including both quantitative and qualitative aspects, the result shows that Vietnam is the optimal destination country for fragmenting production of Thai electronics industry internationally.

Abstract
The objective of this paper is to configure logistics network of high-quality beef in Northeastern Thailand for exporting to Vietnam, which is considered as potential target market. The beef logistics network consists of suppliers which are cattle production regions, existing exporting slaughterhouses, new exporting slaughterhouses, domestic markets, and foreign markets. The mathematical model was developed to determine the optimum networks for distributing quality beef to customer in both domestics and foreign destinations. The logistics networks were configured by determining both physical and behavioral constraints such as supply volume of raw materials, transportation distance, capacity of slaughterhouse, consumer demand for beef, and price of beef. The optimal networks were identified by maximizing the profits of beef logistics network. This study is the foundations for developing a tool for configuration decision of the high-quality beef logistics and supply network to new markets in ASEAN and other countries. The study could be useful for international trade and investment planning in the future.

Abstract
Air Jet Loom (AJL) is a critical machine in textile industries, used to convert thread into fabric. This research uses a leading textile company in Yogyakarta as a study case. Preliminary observation in the case study shows that the AJL machine has a high downtime that affects the overall production process. This study aims to identify critical components of AJL machine and designing maintenance system for AJL machine to reduce downtime. Reliability centered maintenance (RCM) method was used in designing maintenance system by focusing on improving machine reliability. The study begins with the identification of critical components of AJL machine using a fishbone diagram and continued with pareto diagram. For each critical component, time between failure (TBF) data was collected. The collected TBF data is then used to calculate the level of reliability and maintenance schedule. The results found that there are six critical components of AJL machine, i.e. VPM, take up, insertion, kamran, oil circulation, and leno. The preventive maintenance scheduling interval for the six components is VPM 120 hours, belt take up 144 hours, insertion 72 hours, kamran 24 hours, oil circulation 144 hours and leno 96 hours. The proposed preventive maintenance schedule on the six critical components of AJL machine was able to reduce downtime by 30% and increase fabric production by 13%.

Abstract
A maritime inventory routing problem (MIRP) or sometimes referred to as inventory ship routing problem (ISRP) is a tactical planning problem where the ship operator has the responsibility not only for the ship routing and scheduling, but also for the inventory management at one or both ends of the sailing points. Generally, this problem is most often encountered by actors in the industrial shipping segment who transport large quantities of dry or liquid bulk cargoes from several production ports to several consumption ones over a given planning horizon. The bulk products are usually stored as inventories, which levels have to be maintained within certain limits, at or near the production (loading) and consumption (unloading) port. This paper developed a model for assigning a heterogeneous fleet of ships engaged in shipping of multiple liquid bulk products which cannot be mixed for finding a minimum cost routing. We assumed that the ships have multi-undedicated compartments to keep the products separately. The challenging thing in this model is that we considered the allocation of the products into compartments which has been treated so far as a separate planning problem. This stowage onboard the ships is important because it will affect the ship stability and strength. Haphazard stowage will cause ship structural damage because of improper cargo distribution and loss or reduction of stability during a shipping. This model is formulated as mixed-integer linear programming (MILP) model. Several problem instances are randomly generated and solved using LINGO 11.0. The results illuminate that we should develop a heuristics-based approach in order to solve larger instances of the model.

Abstract
Users have a very important role in the service industry. If the users are satisfied with the service, then they will reuse it in the future. Conversely, if they feel dissatisfied, users will look for similar services from competitors. In this research, the case study is XYZ, one of online marketplaces that have begun to evolve in Indonesia. The purpose of this study is to measure e-service quality from the perception of users by using the Kano-IPA integration model. The research methodology used is by distributing questionnaires. Service attributes are based on the dimensions of E-Service quality; consisting Efficiency, Fulfillment, Reliability, Privacy, Responsiveness, Compensation and Contact. The number of service attributes designed is 28. Respondents are users of the XYZ in Cilegon. Importance Performance Analysis (IPA) is one of satisfaction analysis methods that is commonly used to map the level of satisfaction with the level of importance of service attributes. On the other hand, the Kano model classifies service attributes under the category of Must-Be, Performance, and Attractive. The results shown that the Compensation dimension still needed serious attention from the management. The highest level of satisfaction felt by service users was in the Privacy dimension.

Abstract
CNC Machining Center is a type of CNC machine that can does several processes simultaneously. In some cases, this machine is often single used to make a product through several production stages, from raw material to end product. The reason for using a single machine is to avoid material handling time from one production stage on one machine to the next on another machine. In the case of batch production, the use of a single machine will cause the products flow time to be long which will certainly increase the cost of work in process (WIP) inventory. This research was conducted to reduce the cost of WIP inventory of motorcycle spare parts on the CNC Machining Center. Minimization of WIP inventory cost is done through two steps. Step 1 is to allocate three production stages to three serial CNC Machining Centers. Stage 2 is determining the transfer batch size (10 units) is smaller than the production batch size (50 units). The results of this study indicate that the WIP inventory cost for the use of a single machine is Rp. 2.150,250, while the WIP inventory cost for three serial machines is Rp. 202,100.

Diskamtam are the party whose responsible for watering the city park so that need a route and schedule so that it can minimize the operational cost. In the previous research, 2 sector (2nd sector and 4th sector) route is developed by salesman traveling problem. And in this research route will developed by Clark and Wright Saving Heuristic method and considering traffic congestion factor. The output resulting from the route determination process is to minimize transportation cost and develop watering schedule during one-month period. Based on the results of the research it was found that second sector formed five watering routes and fourth sector with six watering routes. Comparison of costs incurred in this research is greater than the previous research for second sector Rp. 9.617.150,00 with an increase in operational cost of 0.69% and the fourth sector Rp. 9.163.416,00 with an increase in operational cost of 0.83%, this is affected by congestion factor.

Abstract
Scheduling is defined as the process of allocating resources over time to perform a collection of tasks within a certain period of time. PT KHI Pipe Industries in Cilegon Indonesia, has been producing high quality longitudinal and spiral weld steel pipes, which is use for oil, gas, water and pile pipes. The company uses FCFS (first come first serve) rule for scheduling their jobs, which means that job processing based on the first incoming prioritizes orders. In October 2018 there was delay in their production, namely 1771 pipes are still in work in process (WIP) of total demand is 6,296 pipes. Based on these problems, this research tries to determine a better production scheduling by getting minimum makespan as scheduling performance. Heuristic and metaheuristic methods used in this research for minimizing the makespan, there are Campbell Dudek Smith (CDS) for heuristic and Particle Swarm Optimization (PSO) for metaheuristic. We also proposed a new heuristic algorithm for this problem. The results show the makespan of each method, there are CDS method: 742.87 hours, PSO method: 711.96 hours, Proposed Heuristic Algorithm method: 694.64 hours, and existing production scheduling of FCFS rules is 746.43 hours. Based on the results, the Proposed Heuristic Algorithm has smaller makespan than the others.

Abstract
Industrial companies that exist today are mainly industrial companies whose business processes produce food can not be separated from supply chain activities, also known as the supply chain management chain. Generally, the scope of the supply chain management chain in food industry companies consists of upstream parts, which are related to the procurement of raw materials for food production needs and in the downstream part, namely the distribution of finished products. In this series of upstream to downstream activities, it involves several system components such as the procurement of raw materials involving suppliers as parties that hold raw materials for company needs in the production process of finished products and procurement for companies as managers, while distribution activities involve the companys marketing department with distributors or consumers. The obstacle that occurs in the supply chain chain in the upstream part is in the process of determining the amount of raw material supply where there is often a mismatch, the raw materials are sometimes excessive or even lacking and this affects the production process which can stop at any time due to lack of raw materials or a buildup of products in the warehouse. In addition, because these procurement activities relate to outside parties as raw material suppliers, sometimes the constraints are separate in determining the right supplier and according to the needs of the company. Whereas in the downstream part it is related to the product distribution process where the company deals with distributors or consumers. Recommended supply chain management model which is a solution model for each upstream activity that can solve all the obstacles that occur in the procurement process and downstream to solve all the obstacles that occur in the distribution process.

Abstract
Introduction The online food delivery service industry has emerged as huge and prospective industry. In this competitive business environment, having and developing loyal customer are essential; yet, research to examine customer loyalty modelling in this industry is limited. Aim of the study This study is designed to assess the applicability of Partial Least Square Modelling to assess the customer loyalty toward online food delivery service. Method This study uses a survey of 439 online food service customers collected from greater Bandung region. The model, including four quality system predictors (efficiency, fulfilment, availability, and privacy), was examined using SmartPLS software. Result The results show that the model of loyalty toward online food has an acceptable Goodness of Fit Index. Further, the R2 of the customer loyalty in the model is 0.67. These results indicate that the method applied is suitable for modelling customer loyalty. Conclusion This study offer an empirical evidence on the applicability of Partial Least Square to model the customer loyalty toward online food delivery service. This result extends the existing methodological and managerial practices to develop loyalty in the online food industry.

Abstract
The focus of this research is to doing analysis and study of public cemeteries as supporters of green space in Bandung regency for 2018 until 2028 period with the aim to determine number of population in Bandung Regency with considering total population, population growth rate, and mortality rate. The method used in this study is ARIMA (P, Q, N). Based on the results of the analysis and study of public cemeteries (TPU) as supporters of Green Open Space in the Bandung Regency area for the period 2018 to 2028, state that cemetery conditions in Bandung Regency require new burial sites. This is evidenced by the results of forecasting (forecasting) of the population per district in Bandung Regency from 2019 to 2028. In making forecasting there are special cases in certain districts. For example, Kutawaringin District can only be forecasted within the next 5 years, because Kutawaringin District is a new subdistrict since 2008, so more historical data is needed to obtain forecasting results over a 10-year period. Based on the conclusions obtained, the authors suggest the Department of Housing and Land Service District Government Bandung Regency to conduct further research, namely the determination of the optimal number of funerals and graves in Bandung district

Abstract
This research is to address a problem of scheduling batches consisting of multiple item parts processed on a batch processor where each item requires a certain processing time which may differ from others. A number of parts are defined as a batch and processed simultaneously with sharing a set up time. A batch can be formed of the parts with different type of item and the processing time of batch equals the longest processing time of parts in the batch. It is assumed that an excessive duration of processing the parts will not lead to any defect, but increase the operating cost. The completed part must simultaneously be delivered at common due date, d. The objective is to minimise total actual flowtime of parts through the shop. An algorithm to solve the problem is proposed and numerical examples are shown.

Abstract
Currently, the success of drilling exploratory and exploratory wells is at the level of 40 years ago, despite the significant improvement of traditional seismic exploration, based on the study of mirrored waves as the single source of information about the structure of the geological environment. It is obvious that to increase the success and efficiency of exploration drilling it is necessary to use additional opportunities of seismic technologies. In "Scientific school of oil and gas seismoacoustics prof. Kuznetsova Ol" developed and tested in practice non-standard seismic technologies that allow a high probability to obtain information about the nature of saturation and fracturing of the geological environment. "Seismic locator of the lateral review" (SVSL) and "Seismolocation of emission centers" (SLEC), highlight (in the observable seismic wave field) and position (in a given volume of a medium) wave diffuse reflection and wave microseismic emissions, which in principle give the opportunity to judge the fracture and fluidnation studied breeds. The same technologies can be used to study the nature and degree of depletion of oil and gas fields in order to improve the efficiency of planned geological and technical measures. Adjustments to existing geological models based on the SVSL and SLEC will allow to increase production rates of new wells for infill drilling, sidetracking, to predict emergency the intervals of absorption or release of drilling mud. The following is a brief list of tasks to be solved and some examples of their implementation in Russia and abroad. The effectiveness of SLBO and SLOE technologies was awarded the prize of the Russian Government in the field of science and technology.

Abstract
A Pull-based, smooth, and repetitive production system can be supported by a lean logistics. Lean logistics itself has derived the importance of delivering parts in periodically. This paper is an implementing of a mathematical model and a heuristic approach from the previous research about supply system for parts into assembly lines. The supply system in this paper occurs on a just-in-time basis and determined for the design of internal milk-run parts supply system form a warehouse to several sub-stations where parts are colected to supply several stations. The most suitable solution is decided from the least material handling cost and WIP or inventory holding cost.
