Abstract

Indonesia is a country that has various natural and cultural resources that can be utilized for tourism. Natural wealth which includes natural tourism, cultural tourism, and others exists in various regions in Indonesia, one of which is Karo Regency. Karo Regency is able to become a tourist destination that can attract tourists to visit. However, in recent years the level of tourist visits has decreased. Therefore, it is necessary to know what factors influence the interest in visiting tourists so that it can be an evaluation for the government to increase tourist visits. This research was conducted by analyzing three influencing variables, namely service quality, tour packages and tourist facilities with data analysis using the Structural Equation Modeling (SEM) method. Based on the results of data analysis it is known that these three variables have a positive effect on increasing interest in tourist visits. Thus, recommendations can be given that can be carried out by the government or the local community by taking into account these three variables.

Abstract

Fuzzy set theory, or fuzzy logic, has been in use in inventory systems since the 1980s, with vaguely defined, ill-defined, or imprecise values, or decisions based on individual subjective beliefs. Provides a framework for describing the parameters that can be passed. There are many uncertainties in inventory management that can arise due to many things, such as: Order Changes, Random Supplier Capabilities, or Unexpected Events. Fuzzy logic as a method of inventory control that provides a framework by considering parameters that are vague or poorly defined, or whose values are imprecise and determined based on individual subjective beliefs make it available. The purpose of this white paper is to review previous studies using fuzzy logic in inventory management to see the uncertainty variables used. The method used is a thematic analysis of articles on the application of fuzzy logic in various industries. The results of the review show that variables like fuzzy logic make it easy to obtain results from uncertainty variables that can be applied to industrial activities to enable manufacturing activities to be carried out effectively and efficiently increase.

Abstract

The aim of this study to review the limited survey of a systematic various existing transportation problems and the application developed by different researchers and applied in some case studies. The methodology applied in this paper through various research papers that available at Google Scholar, Science direct, Elsevier, IOP and another publisher from 2014-2022 (twenty-four international researches). The main purpose of this review paper is to discuss, analyze and the existing forms of various types of transportation problems and their systematic development, Findings show that in addition to the MODI and VAM methods, other methods have also emerged to solve the transportation problem. One of them is Improve VAM (IVAM) that built by Nahar et.al (2018). IVDM on transportation or delivery strategy. Further, this paper concludes that mathematical models and algorithm method of transportation derivatives/techniques of MODI and VAM are most used to optimize single or multipurpose parameters such as distribution cost, profit earned, total transportation time etc.

Abstract

Traffic accidents are one of the highest causes of death in the world, with human behavior being the most dominant factor. Therefore, it is necessary to understand driver behavior as a traffic accident mitigation strategy. This paper aims to understand the behavior of drivers at signaled intersections and to overcome the deviant behavior. The behavior of the driver at the intersection is to stop or cross the intersection. Crossing at an intersection at a red light is deviant behavior. This deviation can occur as violation due to driver aggression or error due to a dilemma when the light is yellow. The influencing factors are personal, speed, acceleration, distance, the presence of other vehicles, and others. The main countermeasure for deviant behavior at intersections is law enforcement, such as the installation of red light cameras. In addition, the behavior of drivers at intersections can be used as a reference in the design of safer intersections.

Abstract

The main purpose of this white paper is to analyze current research on Six Sigma in the auto parts industry and identify opportunities for further research. This study used a systematic literature search of the most recent scientific articles (2013-2022) searched using specific inclusion and exclusion criteria. His two main categories of research goals emerged. The development of Six Sigma and the impact of Six Sigma. In recent years, research on the impact of Six Sigma is the most popular and has always been there from year to year, while research on the development of Six Sigma is the least popular. The study can provide insights to researchers, consultants and quality managers in developing and implementing Six Sigma in the automotive components industry sector. This research found that there is a lot of research on the complete Six Sigma methodology in the automotive component industry, especially research on the impact of implementing Six Sigma. From these findings, the main avenue for future research can be identified, namely Six Sigma Digitalization.

Abstract

Supply chain is basically an integrated system in the process of preparing and delivering products to consumers. This chain is also a network of numerous businesses that are interrelated and have a common objective. This company, which is engaged in the processing of soy sauce using soybeans as its raw material, produces sweet soy sauce and salty soy sauce. Production policy used in this industry was based on the number of requests at the store's sales area and the demand to anticipate fluctuating demand were added 10%. Inaccuracies in the number of requests result in a varied difference between the number of requests and the number of sales, causing overstocking when demand decreases or stockouts when supplies cannot meet demand or commonly known as the bullwhip effect. Based on these problems, this study aims to obtain the right production policy to minimize the bullwhip effect using the CPFR framework. The results of this study show that the bullwhip effect values ​​for sweet and salty soy sauce are 0.812 and 0.814, respectively.

Abstract

The cost reduction and production time reduction are the benefits of 3D printing in the manufacturing industry, which can be developed in printing casual shoes that meet customer needs. Although 3D Printing promises many benefits, many are still doubtful about its application in Indonesia. To examine the potential use of 3D printing in Indonesia, information was extracted about the knowledge of the Indonesian people about 3D printing machines and asking to potential investors for an assessment of 3D printing in Indonesia. Data collection was done through an online survey. Respondents were selected randomly with a purposive sampling technique. Survey results show that 91% of respondents said they already knew 3D printing machines, they also knew that there were various kinds of 3D printing products and various kinds of raw materials that could be used. Prospective investors will assess 3D printing products by taking into account market convenience, product uniqueness, workshop/shop location and availability of specialized human resources.

Abstract

MSME by Mommy House is a business engaged in manufacturing by producing a variety of healthy foods. West Java Province from 2019 the number of MSME engaged in the culinary increase form 1,985,763 units reaching 2,239,092 units at 2021. Management realizes that it’s necessary for using the Supply Chain Operations Reference approach and the Analytical Hierarchy Process (AHP) to gain certainty about Supply Chain Management (SCM) performance, in order to satisfy customer desires with quality products. The MSME by Mommy House SCM process consists of suppliers, manufacturers, distribution and customers with SCM flows in the form of material, financial and information. The performance weighting of SCM uses the AHP approach, with the calculation results on the core plan of 0.113, the core source of 0.299, the core process of 0.332, the core delivering of 0.223 and the core process returning of 0.032. Snorm De Boer normalization the lowest and the highest score is 75 and 100. The highest final value is the make process with a performance value of 29.155 and the smallest is the return process of 3.113. Total supply chain performance value is 75.108 which is in the range of 70 to 90 meaning a good performance indicator.
