Abstract

Today's modern supply chain represents a complex and real-time, organization, resource, activity, information, and data source that is involved in the distribution of products and services ranging from upstream to downstream of the supply chain. In the past 4.0 supply chain technology was not just a linear business function, but as the center of the main process of ecosystems that are in a blind spot chained by value. With information as a foundation in the decision-making process so that information can create integrated and efficiently coordinated supply chains. So that it can show continuity from planning to production, inventory, quality, and price control in each chain. An inefficient distribution that results in mistrust among stakeholders, because it has an impact on the decline and loss of value chain in quality and quantity. Integrity problems from the data collected were found in this study. These findings include the identification of various stakeholders, including farmers, importers to customers, and regulators, as well as their needs, which will be described through the use case, and BPMN. The results obtained are that the main actors (stakeholders) of the system are divided into farmers, importers, processing factories, headquarters, hauling services, and markets (customers) in the distribution of product information flow systems. Suggests tracking and tracing based on real-time data flow of product information coming from each actor in the sugar supply chain that is equipped with an accurate data distribution information support system.

Abstract

Indonesia is a country with 16,056 islands, well known for its natural wonders and cultural heritages. Indonesia’s Travel and Tourism Competitive Index is 4.3. There is a good opportunity in establishing a business involving tour guide and tour package providers. In this paper, feasibility analysis is done based on market, technical, and financial aspect. The market aspect result shows total demand projection, which is 9,881 and 269 for tour guide booking transaction and tour package provider membership respectively during the first year of establishment. The technical aspect result shows the business process design, website design, and the operational need of the business. The total time needed for overall business process is 689.83 hours in the first year. And to operate the business the numbers of employees needed are one each for managing director, marketing, website admin, tour package provider manager, and tour guide manager. Two employees are also needed for each financial department and call centre position. The financial aspect result shows that the NPV of this business is IDR 162,798,046. The payback period is 4.339 years, and the IRR is 24.47%. The salary increase, demand decrease, and price decrease sensitivity are 6.96%, 2.86%, and 0.94% respectively.

Abstract

In recent years, applications using electromagnetic wave technology have grown rapidly. One of them is in the military field, the wave-absorbing material used to avoid detection such as aircraft, ships, or tanks requires a super thin absorbent material which has extraordinary absorption. One of the criteria for a wave absorbing material is a soft magnet and has a high Reflection Loss (RL). This research aims to see the effect of the addition of FeNdB and Mn on the synthesis of Polymer Matrix Composite (PMC) as a wave-absorbing material.The FeNdB milling process and Mechanical Alloying (MA) with Mn were carried out using a Planetary Ball Mill (PBM) at a speed of 1000 rpm for 60 minutes. synthesis of PMC by varying the composition of epoxy resin with magnetic powder 95: 5; 90:10; 85: 5. Based on the characterization results, the optimum RL was obtained at a composition of 85: 5 with a value of -22.40 dB at a frequency of 10.40 GHz and the magnetic properties after the addition of Mn were obtained HcJ 0.116 kOe and Br 0.41 kG. PMC hardness increased with the increase of powder in the sample with the highest value of 29.2 HD Shore D and the adhesion decreased with the addition of powder in the sample with the lowest value of 1 MPa.

Abstract

Patria Donut is one of the start up businesses home-scale donut making established in 2018. Patria Donut produce in accordance with the number of orders from distributors and only in accordance with the desire to generate sales for end buyers. The location is difficult to reach by the customer makes this business unpopular. Seeing this fact, the owner wants to expand his business by opening a cafe in a more strategic location, in Jalan Lombok. We should do feasibility analysis by opening this café. The market is conducted by spreading questionnaires to 100 respondents (target 16-39 years) in Bandung. The results showed a potential market of 86%, 98% available market, and the target market the company aimed at 0.8% of the available market. Meanwhile technical aspects and financial aspects based on secondary data from various sources. The financial calculation obtained from the NVP value for 2020-2024 are Rp 229.258.502,00, the IRR percentage is 26,69%, and PBP is 4 years and 4 months. IRR obtained is greater than the MARR value of 9.95% and NVP is positive. From these parameters, the opening of the Doria Cafe on Lombok Street, Bandung was feasible. We used website to support this business design.

Abstract

Indonesia has managed to get out of the low-income zone and into the middle-income zone. However, Indonesia still has a challenge that is to get out of the middle-income trap zone. These challenges must be resolved by improving the performance of BUMN. Indonesia Port Center Terminal is one of the BUMN subsidiary companies precisely a subsidiary of Indonesia Port Center II (Persero). The purpose of the study was to determine differences in performance indicators before and after the IPO in profitability ratios, namely ROA, ROE, OPM, and NPM and recommendations for performance improvement strategies. The data obtained is based on the 2016-2019 financial statements and questionnaires to expert judgment. The method used is the Wilcoxon Paired t-Test, AHP, and SWOT test. The results of the Wilcoxon Paired t-Test test before and after the IPO were no difference. The results of the company's SWOT analysis are in the position of quadrant I (strength and opportunities). The recommended strategy applied in this condition is to support an aggressive growth policy that prioritizes the strengths and opportunities of the company.

Abstract

The article describes a concept of health and safety to conduct research in Nanomaterial Laboratory in Two Public University in Malang, East Java, Indonesia. The utilization of nanomaterials in the world of education has been done in two universities in Malang, namely Malang State University and Brawijaya University. The nanomaterial laboratory as a means for research and development of nanomaterial science that often creates hazards and risks of work accidents for its users, but things that are often not realized. Dangers and risks of work accidents caused by the absence of standards. This research focuses on hazards and accidents in the nanomaterial laboratory using the HIRA (Hazard Identification and Risk Assessment) method, which is then followed by a variety of independent variables. The population in this study were nanomaterial researchers at two universities in Malang. Based on the results of trials between respondents 'competency expertise with the level of risk of workplace accidents in the nanomaterial laboratory obtained p- value 0.00 (<0.05), meaning that there is a significant relationship between the respondents' scientific conservation and the level of work accident risk in the nanomaterials laboratory. Furthermore, the results of the study were also obtained between the research respondents with the level of risk of work accidents in the nanomaterial laboratory with a p-value of 0.00 (<0.05), meaning that there was a significant correlation between the respondent's research experience and the level of work accident risk in the nanomaterial laboratory.

Abstract

Participatory ergonomics (PE), the origins of which can be traced back to the western ergonomics approach, is an approach that focuses on involving workers to improve safety and health at their workplace. This paper has presented a literature review of studies concerning PE, the methodological approaches used to study PE and PE in industrial developing countries (IDCs). The paper has also explained factors which would seem to pose an extra challenge in applying PE in IDCs and Indonesia. The purpose of this was to provide the reader with a view of how the development of participatory ergonomics today possibly can help solve the problem of occupational safety in small-medium size enterprises (SMEs) in Indonesia.
