Purpose: This study aims to determine the most appropriate contract manufacturing strategy for PT. SA to ensure sustainable fulfillment of its MA baby food products, amidst regulatory changes and operational risks from overseas production. Methods: A mixed-method approach was employed, integrating qualitative methods (interviews and FGDs with Subject Matter Experts using Kepner-Tregoe and Why Tree analysis) and quantitative techniques through the Analytic Hierarchy Process (AHP). The criteria used for decision-making included cost, schedule, delivery, capacity, capability, and quality. Results: The AHP analysis identified schedule (32.95%) and cost (30.31%) as the most influential criteria. For short-term resolution, the strategy “Produce in existing contract manufacturing and distribute using a 3rd party trader” scored the highest (49.56%). For long-term sustainability, “Terminate existing manufacturing and produce in alternative local contract manufacturers in Indonesia” was the optimal choice (31.55%). Conclusion: Selecting the right strategy helps mitigate sales loss risk (up to IDR 97 billion annually), ensures product availability, and aligns with government import restrictions. Each alternative was evaluated for feasibility, risks, and potential savings. Limitation: This study is specific to PT. SA’s baby food segment and may not fully generalize to other industries or products with different supply chain dynamics or regulatory constraints. Contribution: The study contributes a structured decision-making model using Kepner-Tregoe and AHP to optimize contract manufacturing strategies, supporting firms in navigating supply chain disruptions under regulatory pressure.

Purpose: This study aimed to develop a flipbook-based personal development information service model and examine the increase in self-awareness of late adolescents as a measure of its effectiveness Research/methodology: This research used development research methods with an ADDIE design model. The instruments used in this study were validation and practicality sheets, model needs analysis questionnaires, self-awareness questionnaires, interviews, and observations. The data processing used in this research was based on the model's validity and practicality, and N-gain test analysis and Paired Sample t-test using SPSS version 24 were also carried out to evaluate effectiveness. Results: The research results obtained are as follows: 1) assessment of the feasibility of the flipbook-based personal development information service model shows a high validity category with an average value of 91%, and its practicality is considered very practical to use with an average value of 87%; 2) assessment of effectiveness, there is a Sig.2 tailed value of 0.000 < 0.025, so Ho is rejected, and Ha is accepted, as well as an increase in the average (Gain) of pre- and post-test data of 0.60, which is classified as a medium criterion. Based on the research results, the developed product model is effective and contributes to increasing self-awareness among high school students in their late adolescence. Conclusions: The flipbook-based personal development information service model is proven to be valid, practical, and effective in enhancing self-awareness among late adolescents. The product development follows the ADDIE framework and meets the criteria of high validity (91%), high practicality (87%), and effectiveness (N-gain = 0.60; Sig. = 0.000), indicating a statistically significant improvement in students' self-awareness. Limitations: This study is limited to high school students in South Tangerang and does not generalize across broader adolescent populations. The implementation relies on digital literacy and access to stable internet, which may not be consistent across various educational contexts. Contribution: This study introduces a validated flipbook-based model that enhances self-awareness in adolescents through accessible and interactive guidance services.

Purpose: The study assessed the effect of e-payment methods on the growth of e-commerce in Uganda, specifically focusing on the impact of e-wallets/e-cash, debit/credit cards, and money transfer services on e-commerce growth in Kampala. Research/methodology: A cross-sectional design was used with a sample of 384 participants. Data were collected through structured questionnaires, cleaned, organized, and analyzed using SPSS, employing correlation and regression models for inferential analysis. Results: The study found that e-payment methods, including debit/credit cards, money transfer services, and e-wallets/e-cash, positively and significantly associate with e-commerce growth. However, while debit/credit cards and money transfer services significantly predict e-commerce growth, e-wallets/e-cash have a positive but insignificant effect. Overall, e-payment methods account for 33.1% of the variation in e-commerce growth. Conclusions: E-payment methods, especially debit/credit cards and money transfer services, significantly contribute to e-commerce growth in Kampala. E-wallets show a positive but insignificant effect. To achieve sustainable impact, further support is needed for e-payment adoption. Limitations: The study focused on a limited range of e-payment methods, excluding others used in the sector, which affects generalizability. Additionally, only Kampala was studied, though other regions in Uganda also engage with e-payment systems. Kampala, as the central business hub, is a key area for innovations that spread to other cities. Contribution:. E-payment systems significantly predict e-commerce growth. Key e-commerce players should encourage the use of e-payments to foster trade growth, as their adoption will help stimulate e-commerce activity.
