Abstract

The study of networks in the internationalization process of SMEs has become an interesting discussion, this condition is because each country has unique dynamics in utilizing existing networks. The results of the analysis of the 20 articles in this study show that being proactive in the network community will strengthen relationships with partners and implementing an alliance strategy will strengthen the position of SMEs in increasing competitiveness and expanding markets. This condition occurs in both developing and developed countries. The dominant factor influencing the speed of the internationalization process is social and business network relations that begin with social ties. Of the 8 articles that discuss networking in the process of internationalization in developed countries (China, Central America, and East America), it shows that the government as an institution that has an important role in the internationalization of SMEs needs to design a framework in the form of policies that encourage the acceleration of various forms of collaboration between businesses. Meanwhile, 12 articles that discuss the process of internationalization in developing countries show that for the expansion and growth of SMEs a social network structure is needed, and the role of ethnic (group) ties in internationalization.

Abstract

The present study reports the first comprehensive study on management preventing efforts on disease transmission has been carried out by washing hands with soap since hands are the most transmittable disease medium. Hands should always be clean by using washing hands with soap (CTPS) following to the correct steps. Before practicing CTPS, respondents were given counseling about hand washing by carrying out 7 steps of washing hands starting with rubbing the palms, back of the hands, between the fingers, closing the right and left fingertips, rubbing the thumbs, cleaning the fingertips then ending by wiping the wrists, rinse with water and dry. The results of observations in class action research on 47 respondents that are university students in Jakarta Indonesia concluded that most respondents (59.57%) had practiced CTPS correctly. The results of the observations of the CTPS steps or steps can showed that most respondents (86.02%) have carried out these steps, in fact all respondents have carried out step 1 and step 7 correctly. The quality of the implementation of the CTPS steps, which were mostly good, was made possible by the educational factors possessed by the respondents and the information obtained during the counseling before the respondents carried out the CTPS practices. The good quality of the implementation of the CTPS steps was also made possible that most of the respondents around 74.47% were women.

Abstract

Inventory forecasting is crucial in effective supply chain management and cost reduction. However, traditional forecasting techniques face significant challenges due to the complexity and variability of demand patterns. This study explores the use of K-means clustering, a data-driven approach that can improve inventory forecasting accuracy. By grouping inventory items based on their unique demand profiles, we can create personalized forecasting models for each cluster. This technique enhances demand estimation, helping businesses make informed decisions and optimize their inventory. Our research delves into the use of K-means clustering to identify patterns and similarities within historical demand data. This clustering process divides inventory items into groups with similar demand characteristics. By applying specific forecasting models to each cluster, we achieve greater precision in our predictions. The proposed methodology is rigorously evaluated using real-world inventory datasets, and the results demonstrate its significant superiority in forecasting accuracy compared to conventional non-clustered methods. This study offers compelling evidence and valuable insights for practitioners seeking to improve their inventory management practices through data-driven techniques.

The pharmacological properties of turmeric rhizome include anti-inflammatory, anti-immunodeficiency, anti-viral. Anti-bacterial, anti-fungal, anti-oxidant, anti-carcinogenic, and anti-infectious. This study aimed to identify the immunomodulator activity of curcuminoid extract of turmeric rhizome against the increase of leucocyte and its components, lymphocyte and neutrophil in white Galur Wistar rats that had been injected with Staphylococcus aureus. These test animals were given curcuminoid extract in VCO 100 mg/ml on a dosage of 1 ml, 0,5 ml, 0,25 ml curcuminoid powder 200 mg/kg body weight. Curcuminoid was suspended in Na CMC0,5%, Levamisole 25 mg/kg of body weight suspended in Na CMC 0,5%, VCO 1 ml. For the negative control, merely Na CMC 0,5% was given. The extract was orally given daily for 14 days. On the 4th day, Staphylococcus aureus was injected intra-peritoneally. The rats’ blood was then drawn from the heart and was observed to calculate the volume of the leucocytes, lymphocyte, and neutrophil which was conducted using flow cytometry.The findings suggested that there was a significant difference between the immunomodulatory activity of the curcuminoid extract in VCO at the doses of 1 ml, 0,5 ml, 0,25 ml on the increase in leucocyte, lymphocyte, and neutrophil compared to that of the negative control.Therefore, the findings of this study indicated that the extracts of curcuminoid in VCO could increase the number of leucocytes, lymphocytes, and neutrophils. Thus, the curcuminoid extract of turmeric rhizome in VCO potentially possessed immunomodulatory activity.

Abstract

The With the advancement of computer, electronic, and telecommunications technology, there has been a significant change in the world of applications, which makes it easier for humans to carry out various activities, both at work and in interacting on social media.CV. Albahritech faces the challenge of not having a quick and easy office equipment maintenance application. This limitation can have a negative impact on company operations. Currently, the maintenance process still relies on communication via WhatsApp or phone, which causes customer appointments to be missed or forgotten due to the large number of calls for customer maintenance services that cannot be fulfilled. In addition, transactions and visit reports are not properly recorded, which can cause customers to experience delays in getting treatment services or even cause customers to look for other treatment services.The currently designed application uses a blockchain-like decentralized network model, known as a DApp. This DApp has several important features that utilize blockchain technology[1], including the ability to make payments using cryptocurrencies such as Ether and the feature to record service lists for customers. In this application, smart contracts are used to create a mechanism of trust and automation in agreements or deals between the parties involved. This ensures that agreements and transactions made within the app are transparent, secure, and without the need for a third party. In addition, the app also uses IPFS for customer data storage. IPFS is a peer-to-peer file distribution system that serves to store and distribute data on the interne[2]t. The use of IPFS in this application enables distributed and decentralized data storage, thereby improving data security and reliability.
