Handwashing with Soap (CTPS) is the activity of cleaning hands using clean, running water and soap to remove dirt, oil, and various germs such as viruses, bacteria, and parasites that may cling to the skin. As one of the most effective, simplest, and most affordable methods of preventing infectious diseases, CTPS is highly important to practice consistently, especially among students at Public Elementary School 283 located in Waitomu Hamlet, Leihitu District, Central Maluku Regency. However, observations indicate that after school activities or playtime, several students still show reluctance to wash their hands, which may be influenced by low awareness, limited understanding of hygiene, insufficient supervision, or the absence of strong daily habits related to cleanliness. This issue reflects the need for more structured hygiene education, continuous reminders, and interactive learning methods to instill good handwashing habits. In addition, improving supporting facilities—such as accessible handwashing stations, adequate soap supply, and visual posters—can motivate students to practice CTPS more regularly. Strengthening CTPS awareness and habits is expected to reduce the risk of disease transmission, foster a healthier school environment, and encourage students to adopt lifelong hygiene practices that benefit both their personal well-being and the wider community.

The revocation of Pinkflash's cosmetic product distribution license by the Food and Drug Supervisory Agency (BPOM) has once again attracted public attention after the brand experienced a similar incident in 2024. This crisis raises questions about Pinkflash's public relations strategy in maintaining consumer trust and preserving its brand reputation. This study aims to analyze Pinkflash's public relations strategy and measure the impact of the crisis on public perception through social media sentiment analysis using Brand24. The research method used is a descriptive qualitative approach. The main data in this study was obtained from official documents by BPOM and official brand statements, which were then analyzed using content analysis and sentiment analysis using Brand24. The results of the study show that Pinkflash's crisis response only temporarily dampened negative sentiment. The root of the problem lies in weak governance, which led this study to conclude that reputation can only be rebuilt through comprehensive improvements to the quality of its systems and supply chain, with a commitment to honest operations as the key.

Production quantity planning is a crucial component in the bottled water industry (AMDK) to ensure that consumer demand is met efficiently. Inaccuracies in determining the amount of production can lead to overproduction and supply shortages, which ultimately leads to increased operational costs and decreased customer satisfaction. This study applies the Sugeno fuzzy logic method to predict the amount of production based on two main variables, namely weekly demand and raw material stock. The analysis stages include the fuzzification process, the preparation of the rule base, inference using the zero-order Sugeno method, and defuzzification using the Weighted Average (WA) method. The data used is synthetic data that represents the operational conditions of the medium-scale bottled water industry. The results show that the Sugeno fuzzy system is able to produce production predictions that are adaptive and responsive to fluctuations in demand and stock availability. This model provides consistent and stable output, so it can help companies in determining the optimal production amount. These findings confirm that Sugino's fuzzy approach can be an effective decision support tool in bottled water production management, especially in the face of uncertainty and variability in market demand.

In the fast-moving fashion retail industry, supply chain efficiency is a key factor in operational success. Heybeb Factory Outlet, as one of the retail business actors, faces challenges in managing the flow of goods from upstream to downstream, particularly in balancing demand between offline (physical stores) and online (e-commerce/marketplace) channels. This proposal aims to design and analyze the logistics workflow starting from goods ordering (restocking) from the central warehouse, the goods receiving process, rigorous Quality Control (QC) procedures, storage in a dedicated transit warehouse, and the stock distribution mechanism (stock split) for the two sales channels. The main issues identified include the risk of overselling in one channel while stock accumulation occurs in another, as well as the potential for defective items to pass through due to an unstructured QC process. This study employs a descriptive qualitative approach by mapping out an ideal Standard Operating Procedure (SOP). The expected outcome is the development of an integrated inventory management system capable of minimizing return rates caused by defective items and maximizing inventory turnover through accurate stock allocation between online and offline divisions.
