Automating the Extraction of Words and Topics in Indonesian Using the Term Frequency-Inverse Document Frequency Algorithm and Latent Dirichlet Allocation
Full text linkKeyword extraction and topic modeling in the analysis of Gojek user reviews in Indonesian are very important. By understanding user preferences and needs through keyword extraction, as well as grouping user reviews into different topics through topic modeling, stakeholders can use the information to further improve services. This research uses TF-IDF and LDA approaches to analyze text data from Gojek user reviews and feedback. The data spans from Nov 5, 2021, to Jan 2, 2024, totaling 225,002 rows. Each row includes username, content, time, and app version. The focus is on content reviews. The average length is 8 words, with a maximum of 104 and a minimum of a few words. The variability indicates a non-normal distribution. Preprocessing is conducted to maintain topic analysis accuracy. The TF-IDF method is used to extract relevant keywords, while the LDA approach is used to model the topics in user reviews. The topic analysis reveals patterns in Gojek user reviews. The first topic discusses experience, services, and affordable pricing. The second emphasizes app usability and benefits. The third relates to promos, discounts, and vouchers. The fourth reflects positive evaluations of service quality. However, the fifth topic highlights high costs and app issues. The sixth underscores overall user satisfaction and service convenience. Testing on the topic model yielded a coherence level of 0.509, indicating that the model's topics demonstrate a good level of consistency in finding relevant topics from Gojek user review data. The use of a combination of TF-IDF and LDA in Indonesian text analysis, particularly in the context of Gojek user reviews, is an important step in enhancing understanding and utilization of text data to improve overall user experience.
Implementation of the GBI Bethany Tower of Christ Congregation Management Information System Design
Full text linkAlong with the development of the digital era and pandemic conditions have increased the need for systems capable of working remotely. This motivated the researchers to conduct observations at the Bethany Tower of Christ Church. Based on observations and interviews that have been conducted with church pastors and deacons, it is found that the system already owned by the church has a lack of features, one of which is the feature of submitting requests to the church. In addition, there is also a need to update features related to adding devotionals, news, and posts to make it more practical and efficient. The development of this system uses the Waterfall method in which in the process the researcher first conducts direct observation and research at the Bethany Tower of Christ Church followed by analyzing the needs of the church and congregation which results in the design of a congregation management system. As for after the design is done, the system implementation is carried out. After that, researchers conducted testing of system maintenance. Based on the overall results obtained from the survey of respondents' assessment of the website, an average assessment of 87.3% was obtained, indicating that the website is feasible and has impressive respondent satisfaction. Researchers still find shortcomings in the system created, namely the lack of some features and the presence of bugs that need to be fixed. However, researchers still hope that the designed system can be useful for congregations and churches and can continue to be developed and maintained so that the system can be better
THE EFFECTIVENESS OF MAGGOT (Hermetia illucens) AS CATFISH FEED IN AQUAPONIC FARMING SYSTEMS
Full text linkThe nutritional composition of maggots can be utilized as a substitute for pellets to reduce the cost of purchasing fish feed through an aquaponic system integrated with spinach plants. This study aimed to determine the effectiveness of maggots as catfish feed in an aquaponic farming system. The study was conducted from February to July 2021 at the Agroecotechnology Experimental Farm of Trilogy University, Jakarta. Meanwhile, maggot proximate testing was carried out at the Center for Agro Industry, Bogor, West Java. The experiment employed a one-factor Randomized Group Design (RAK) (catfish feed) with three levels: pellets (P0), maggot (P1), and a combination of pellets and maggot (P2). The results showed that using maggot as a substitute for catfish feed in the aquaponic system was considered effective because the weight and length of catfish harvested were as good as those fed with pellets. However, the growth of spinach plants integrated with catfish through the aquaponic system is still not optimal compared to conventional cultivation in general. Nevertheless, the growth results were still better than those integrated with catfish fed with pellet or combination feed. The spinach growth results indicated that the plant had a height of 18.20 cm, a total of 6.14 strands of leaves, a stem diameter of 2.25 mm, a root length of 35.51 cm, and a weight of 20.97 grams

PERANCANGAN STRATEGIC COST MANAGEMENT DENGAN METODE TARGET COSTING PADA RUMAH PRODUKSI MANISAN SATRIA, CIREBON
Full text linkThis study aims to design strategic cost management with target costing method at Satria Confectionery Production House, Cirebon. This study focuses on three types of sweets that are in great demand by consumers, namely candied mango, rosella, and cermai. This research data uses primary and secondary data. Data collection techniques in this study used interview, observation, and documentation techniques. This study conducts value chain analysis and SWOT first to determine the internal and external environmental factors of the production house, the position of the production house and identify the primary and supporting activities contained in the production house. Currently, Satria Cirebon Confectionery Production House tends to be in a differentiation position. The results of this study show that the calculation of total costs using the target costing method provides a more accurate calculation by carrying out the product development stage, choosing a target price, getting an allowable cost, drifting costs, and value engineering. By doing value engineering, it can reduce drifting costs so that they do not exceed or equal to the predetermined allowable costs. This value engineering can result in product design improvements, changes in material specifications, and process modifications. By using target costing, the total cost charged to the product can be reduced without reducing product quality. Satria Cirebon Confectionery Production House can increase profits and compete in the confectionery market without increasing the selling price of products.Keywords: Allowable Cost, Drifting Cost, Strategic Cost Management, SWOT Analysis, Target Costing, Value Chain Analysis, Value Engineerin
Empowering Diagnosis: A Review On Deep Learning Applications for COVID-19 and Pneumonia in X-Ray Images
Full text linkThe emergence of COVID-19, a highly contagious virus capable of infecting both the upper and lower respiratory tracts, has led to one of the deadliest pandemics in modern history, claiming millions of lives worldwide. Early and accurate detection of this rapidly spreading disease is crucial for effective containment and saving lives. Chest X-ray (CXR) stands out as a promising diagnostic tool due to its accessibility, affordability, and long-term sample preservation. However, distinguishing COVID-19 pneumonia from other respiratory ailments poses a significant challenge. This article delves into various approaches utilized for COVID-19 detection and the hurdles encountered in this endeavor. The imperative for developing automated detection systems to mitigate virus transmission via contact is underscored. Notably, deep learning architectures such as ResNet, Inception and Googlenet have been deployed for COVID-19 detection, albeit with a focus on identifying pneumonia cases. Discriminating between COVID-19-induced pneumonia and pneumonia caused by other pathogens remains a formidable task, demanding innovative solutions for accurate and timely diagnosis
