Abstract

PT XYZ is a company engaged in the household electronic equipment industry, one of which is refrigerator products. Two machines that are also responsible for the refrigerator production process are cold roll forming machines and PU injection machines. The refrigerator production process at PT XYZ is still considered ineffective because it does not reach the predetermined production target. The overall equipment effectiveness (OEE) method can assess the level of effectiveness of a machine based on three categories, namely availability, performance, and quality. Based on the results of calculating machine effectiveness using the OEE method, the two machines are below the ideal limit, namely 71.5% for the CRF machine and 57.22% for the injection machine, with a CRF machine performance value of 73.99% and 59.89% for the PU injection machine. An analysis of causes and solutions was carried out using the failure mode and effect analysis (FMEA) method using the risk priority number (RPN) assessment. The causes of low machine performance levels can provide solutions to improvements that must be made by the company. The recommended solution for the company is to apply preventive measures by adding UPS and generators to the factory, adding machine component damage detection sensors, and redesigning the jig.

Abstract

The development of information technology has impacted current business behavior, affecting both users (customers) and business owners. Everyone is competing to maximize the use of information technology, whether to facilitate transactions or to improve business management efficiency. This situation is also experienced by CV. Florence Collection, a micro, small, and medium enterprise (MSME) operating in the garment industry, which faces several challenges in managing its business using a manual system. For instance, customer and transaction records are managed using Microsoft Excel, resulting in manually generated reports that are prone to recording errors. Additionally, customers have limited access to information during the ordering process, and payment verification by the business owner is not efficient. Based on these challenges, this study proposes the design of a web-based system for managing the operations of CV. Florence Collection. The system design follows the System Development Life Cycle (SDLC) method, consisting of four stages: planning, analysis, design, and implementation, using PHP as the programming language and MySQL as the database. The proposed system is tested using the blackbox testing method. The designed information system can be implemented by incurring implementation costs, such as hosting, domain, maintenance, and development expenses.

Abstract

Reviews and ratings on apps store show how users perceive an app. This is an important aspect that companies must pay attention to in order to plan improvement strategies. However, there is an inconsistency between reviews and ratings, which makes it difficult to take corrective action. Detikcom, one of the main players in the digital media industry in Indonesia, also faces this similar problem. On Google Play Store platform, it is known that Detikcom's 1-star rating (13%) is one of the highest compared to its competitors. However, the inconsistency between ratings and reviews can be found frequently in the review section. Reflecting on this case, this study focuses on building a model that can identify sentiment using the Naïve Bayes Classifier method and identifying the main driving factors of each sentiment category using K-means Clustering and word cloud. Based on the results of the developed model, the tendency of Detikcom user sentiment is generally positive (67.16%) with a test accuracy of 87.84%. The presence of positive sentiment is based on keywords such as “accurate”, “trusty”, and “up to date”, while negative sentiment is based on keyword “ads”.

Abstract

This research aims to increase social media traffic on Instagram of Buketby.06 by applying the Social Media Optimization (SMO) and the EPIC (Empathy, Persuasion, Impact, Communication) model. Buketby.06, an MSME engaged in the production of flower bouquets, faces challenges in increasing social media reach and interaction which impacts sales. Using the EPIC model, promotional effectiveness is analyzed through four main dimensions: empathy, persuasion, impact, and communication. This research also utilizes the SMO method to optimize the content and visual strategy of the Buketby.06 Instagram account. The research results show that the persuasion dimension has the greatest influence on increasing social media traffic, with the highest average score of 3.72. Implementing SMO, including optimizing visual content, using relevant hashtags, and interactive captions, has significantly increased user engagement. Instagram insights before and after improvements show increased engagement (37%), including the number of likes, comments, and shares. The designed strategy not only increases Buketby.06's visibility but also strengthens brand identity through content that is interesting and in line with audience preferences. This research concludes that the combination of the EPIC and SMO models is an effective approach to overcoming social media traffic problems in MSMEs. It is hoped that consistent and data-based strategy implementation will provide long-term benefits for Buketby.06's business development.

Abstract

The business process improvement at the Research and Community Services Center (LPPM), at a private university in Jakarta, was initiated due to unclear Standard Operating Procedures (SOPs) and the introduction of a new operational mechanism. The main objective of this research is to analyze and map the current business processes to clarify existing workflows. The IDEF0 method is used to identify and evaluate these processes, while the overall analysis follows Business Process Improvement (BPI) principles. The focus is on three core processes: proposal submission, fund disbursement, and reporting—each essential to research, community service, and publication activities. Improvements are proposed through the development of a revised SOP and the design of an online database system. These enhancements are based on interviews with key stakeholders, including the Head of the Center for System Development, LPPM officials, and staff. The use of the IDEF0 method significantly assists in identifying the roles and responsibilities of involved parties in each process. It provides a structured approach to evaluating and refining workflows. As a result, a new database system is being designed to support better data management and documentation at LPPM. This system will be built upon the improved processes identified through the IDEF0 analysis, ensuring more efficient and transparent operations.

Abstract

Using earphones or earbuds while driving positively and negatively impacts the driver. Congestion is a condition that causes motorists to use these hearing aids. However, the use of hearing aids while driving can threaten the safety of drivers and other drivers. The Bumi Serpong Damai (BSD) area is an area with many motorcyclists, so it can be a reference for motorists to pay attention to the dangers of using earphones while driving. Using earphones while driving, motorcyclists often do not focus on road conditions. Moreover, motorists can be indifferent to signs and other motorists. Therefore, a study was conducted on the use of hearing aids by two-wheeled riders in the BSD area to reveal the underlying problems associated with the use of hearing aids when driving. This study was conducted through the distribution of questionnaires and data processing using the chi-square test and logistic regression. This study aimed to determine motorcyclists’ level of awareness about the dangers of using earphones while driving. The result showed that a relationship exists between the frequency of use and driving comfort; the dominant factor affected by using hearing aids while driving is a reduction in emotions due to traffic jams. This study recommends that the government address traffic congestion due to its strong impact on driver emotions. For motorcyclists, it is advised to keep the earphone volume low to maintain focus on traffic signs and surrounding sounds.

Abstract

Vehicles are a means of mobility for society. However, the use of vehicles cannot be separated from the risk of accidents that may occur. In Indonesia, 133 million motorcycle accident cases were recorded in 2019. Accidents are influenced by many factors, one of which is brake failure. Brake failure itself is caused by overheating of the brake disc. Modifying the braking system is one of the measures taken to prevent overheating in the braking system. The application of braking system modifications on motorcycles may also influence rider behavior when on the road. In this study, an identification was carried out regarding the use of modifications to braking system components and their impact on motorcycle rider behavior, observed from several aspects: speeding, lane filtering, and panic braking. The identification was conducted using a questionnaire containing questions on the braking components modified by riders and their riding behavior related to such modifications. Based on the analysis of the data obtained, it was found that there were no significant differences in rider behavior across the three aspects—speeding, lane filtering, and panic braking—between different types of motorcycle braking system modifications.
