Abstract

The objective of this research is to examine the factors that led to the cessation of imports of certain varieties after the crisis. This analysis proposes four alternative working hypotheses. Data from 100 products was taken. Several influencing factors reveal the impact of the economic crisis on imported varieties. More expensive varieties tend to experience an increased probability of stopping importation. This may be due to a decrease in purchasing power during the crisis, which makes expensive products less desirable. Geographic distance also plays an important role. More distant countries produce varieties with a higher probability of stopping imports, this could be due to higher transportation costs for varieties from distant countries. Varieties with a larger market share originating from countries with higher incomes tend to be more stable in the market during the crisis. Likewise, additional per capita income limits the probability of stopping imports to only 3.7%. This suggests that varieties from countries with high incomes or those with large market shares may have competitive advantages that make them more resilient to the impact of economic crises. Reducing imported varieties can hurt consumer welfare because it can reduce product choices and increase prices. Short-term estimates indicate a 9.5% decline in consumer welfare from imported goods.

Abstract

Analysis of public sentiment towards celebrity endorsements on social media is very important to understand the public's response to promotional campaigns involving celebrities. In this study, we combine the VADER labeling method with the Support Vector Machine (SVM) method to analyze public sentiment toward celebrity endorsements on social media. Data is taken from various social media sources such as Twitter, Instagram, and Facebook. The data is pre-processed to ensure data accuracy and relevance and then labeled with the VADER method to determine the positive, negative, or neutral sentiment of the text. The labeled data is then extracted for features and used to train the SVM model. The trained SVM model is then validated using test data to measure its accuracy and performance. The results of the analysis provide useful insight into public sentiment towards celebrity endorsements on social media and can provide recommendations for stakeholders regarding this matter. Overall, combining the VADER labeling method with SVM in analyzing public sentiment towards celebrity endorsements on social media shows more accurate results and can provide practical benefits in marketing and promotional strategies. The results shown using the Support Vector Machine method with a ratio of 80:20 can provide average precision results of 77%, recall of 100%, f1-score of 87%, and accuracy of 76.92%. Twitter application user sentiment shows that 77% (338 data) of Twitter user reviews provide positive sentiment and 23% (119 data) provide negative sentiment reviews from a total of 517 data. Suggestions from researchers are that in future research they can add more data to make modeling easier to provide higher accuracy values. Using other classification and performance evaluation methods, such as Naive Bayes, Decision Tree, Fuzzy, or Deep Learning. Use other data processing tools, such as RapidMiner, Jupyter Notebook, RStudio, or others.

Abstract

This study aims to analyze the role of the adoption of technology and digital devices in facilitating business processes in the tourism industry in terms of delivering interactive information to tourists, especially foreign tourists. This study uses a qualitative method. Data collection methods used in the study are literature reviews, field surveys, and observations. The results of the study show that many foreign tourists are active and regular in using information and communication technology with laptops, smartphones, and the Internet. The results of the study also concluded that applications such as digital maps are the most popular devices for planning travel. Although the demand for digital solutions is very high, there is a gap between the technology preferences of foreign tourists and the ability of industry players to adopt technology, the majority of tourism industry players still rely on conventional methods. Foreign tourists who are currently dominated by the digital generation show a fast understanding and adaptation of technology, this should be responded to quickly by tourism business actors in Indonesia in developing digital devices. The tourism sector needs to improve technology integration to improve the efficiency and relevance of information services. To meet the needs of foreign tourists and technology-savvy tourists, it is important to develop technological devices that can be used to provide information and are easily accessible

The title Complaint Service Information System is based on the need for technological solutions to improve the quality of public services, especially in handling public complaints. This system was chosen because it facilitates more efficient complaint reporting, increases transparency, and speeds up responses to issues raised by the public. By applying information technology in handling complaints, it is hoped that we can create a public service environment that is more responsive, open and adaptive to the ever-growing needs of society. The process of creating a complaint service information system involves several main stages. First, the needs analysis stage is carried out to identify and understand the needs of users and related parties in handling complaints. This involves a survey and analysis of associated documents. Next, the system design and design stage involves database structure, user interface, and business logic. This Information System design process involves critical steps to ensure the success and effectiveness of the system, including coding, creating a user interface, and setting up a database. The results of designing the Complaint Service Information System include a simple and responsive user interface, an online complaint form, a status tracking system, and analytical reports. A structured and secure database stores, manages, and retrieves complaint data. Afterwards, the implementation phase involves running the entire system and, if necessary, data migration. Through the creation of this Information System, it is hoped to evaluate the impact of the level of accessibility and ease of navigation in the system on employee performance in searching, monitoring and managing incoming complaints. With a web-based approach, this system provides easy, fast access for users from various locations and increases transparency in managing services provided to the community.

Abstract

Sea transportation is also very much needed in the processing industry for ships and passengers and the flow of goods. Suppose the incoming ship can be seen as a sender of goods or the processing industry itself. This is supported very well by the cargo and costs for sea transportation, with much cargo at a relatively low cost. Analyzing the relationship of foreign sea transportation with the regional GDP of the processing industry sector. From ship visits consisting of total and units to passenger visits consisting of passenger arrivals and departure, for variable analysis using correlation and hypothesis testing. The results of overseas sea transportation with the GDP Regional the processing industry are for the correlation results of ship visits from units (0.613) with a strong and total correlation (0.596) with a moderate correlation, for passenger arrivals (0.262) and passenger departures (0.280) both have a low correlation relationship, for the unloading flow of goods (0.607) has a strong correlation. So the visits of foreign sea transportation ships with the GDP Regional of the processing industry sector have a significant relationship of (0.00) from the unit or total ships; for passenger visits, both do not have a substantial relationship for passenger arrivals (0.141) and passenger departures (0.115). The flow of unloading of goods has a significant relationship of (0.00). The greater the number of ship visits and the flow of unloading of goods, the higher the GDP Regional of the Processing Industry Sector, but the increasing number of passenger visits has no relation to the GDP Regional of the Processing Industry Sector.

Abstract

Health is the most important and primary thing in human life. Industry and human lifestyle development have both positive and negative impacts. One of the adverse consequences to be aware of is the proliferation of a variety of degenerative diseases. Sidaguri leaves (Sida rhombifolia L.) grow naturally on roadsides, grasslands, forests, fields, areas exposed to bright sunlight, and slightly sheltered places. It is a plant that is widespread in tropical areas ranging from lowlands to 1,450 m above sea level throughout the world. The plant's chemical content includes alkaloids, hypoparin, flavonoids, triterpenoids, sterols, sugars, vaccissinol, vaccissinone, betaine, and phenylalanineSidaguri leaves (Sida rhombifolia L.) are medicinal plants from the Malvaceae family. Almost all parts of this plant can be used for medicinal purposes, particularly in alternative medicine. This study aimed to determine the total saponin content in a 70% ethanol extract of Sida rhombifolia L. Sidaguri leaves, extracted using the maceration method and a 70% ethanol solvent. Using vanillin, H2SO4, and diosgenin as standards, we used UV-Vis spectrophotometry to find out how much total saponin was present. We measured antioxidant activity using the DPPH free radical scavenging test. The test showed that the 70% Sidaguri ethanol extract had a total saponin content of 196.28 ± 1.60 mg DE/g. It also had an IC50 value of 208.63 ± 7.73 mg/mL against DPPH in the antioxidant activity test. This shows the potential of Sidaguri leaf extract as a natural antioxidant.
