Kopi robusta (Coffea canephora) merupakan salah satu komoditas unggulan yang berada di Provinsi Lampung. Selain sebagai olahan minuman, biji kopi robusta juga dapat dimanfaatkan sebagai bahan tambahan alami dalam sediaan produk kosmetik. Masker gel peel-off merupakan salah satu jenis produk kosmetik yang dapat berfungsi sebagai anti-aging pada wajah. Pada penelitian ini, formulasi masker gel peel-off berhasil dipreparasi dengan memanfaatkan ekstrak biji kopi robusta. Metode formulasi masker gel peel-off dilakukan melalui proses in-situ. Hasil uji fitokimia menunjukkan senyawa metabolit sekunder yang terkandung dalam ekstrak biji kopi robusta yaitu alkaloid, flavonoid, saponin, dan tannin. Analisis spektrofotometer UV-vis menunjukkan kadar senyawa flavonoid sebesar 5,86 mg/g. Hasil uji pH masker gel peel-off menggunakan ekstrak kopi robusta sebesar 5,3. Masker gel peel-off tidak menyebabkan reaksi iritasi pada kulit. Sifat fisik dari masker gel peel-off terlihat berwarna coklat dengan bentuk semisolid. Hasil uji aktivitas antioksidan masker gel peel-off menunjukkan nilai IC50 sebesar 7,104 ppm. Dari data yang ada dapat disimpulkan bahwa senyawa flavonoid dalam ekstrak biji kopi robusta sangat berpengaruh terhadap aktivitas antioksidan dalam formulasi sediaan masker gel peel-off.

Previous research has highlighted the primary objective of social entrepreneurship as balancing social and commercial purposes. Social entrepreneurs face significant challenges in managing their ventures, and there is a pressing need to equip students with the necessary knowledge and skills to overcome these challenges through social entrepreneurship education. To address this need, the authors propose a curriculum matrix based on the Identity Capital Model to aid students in achieving social entrepreneurship objectives while incorporating the principles of innovation and sustainability. The proposed curriculum matrix was developed based on data collected through semi-structured interviews with successful youth social entrepreneurs. The sample size was determined using data saturation. The authors analyzed the backgrounds, personal experiences, motivations, and difficulties encountered by participants in launching and operating their social enterprises using the Narrative Analysis Theory of William Labov and Joshua Waletzky. The Identity Capital Model was used as a theoretical framework to identify the key factors contributing to the success of youth social entrepreneurs.

Customer satisfaction is perceived as business strategy’s key component and critical differentiation in a competitive marketplace. The recorded huge transactions per day in marketplaces can be used as useful information to evaluate customer satisfaction. A sophisticated method, such as data mining, is necessary to analyze this massive, multifaceted, and versatile empirical data generating accurate predictions. This research purported to investigate marketplace customer satisfaction as a reference to determine service and quality improvements. In conclusion this study draws two conclusive results: (1) The majority of marketplace consumers preferred the lead-time sensitive over price-sensitive; and (2) The Neural Net empirically showed as the most appropriate robust data mining technique among other techniques to predict marketplace customer satisfaction indicating by fittest accuracy, F score and ROC curve

This article aimed to do research on the economic empowerment of rural women using Participatory Action Research approach. PAR required performing research to define a problem or implement information as solutions to problems that have been defined. PAR is "research by, with, and for people" as opposed to "research on person." Participatory action research is participatory in the sense that it is a necessary condition that people play a key role and have relevant information about the existing social system (community) under review, and that they participate in the design and implementation of the action plan based on the findings of the research. This research was preceded in the search for problems faced by women in Jatisari Village, Lampung Province. The solutions obtained were in the form of providing knowledge, entrepreneurial skills, and examples of how to produce innovative products by utilizing the natural resources around them. Empowerment activities include three stages, namely: (1) Providing counseling about the possible benefits of natural resources in the environment as products for women’s needs by providing examples of the use of plants that are easy to obtain and grow, for example aloe vera which is easily found in the yard to produce a product; (2) Provide counseling on how to become a woman entrepreneur and analyze household products with high demand for daily needs (eg liquid dish soap); and (3) Demonstrating how to use aloe vera as a component in the manufacture of liquid dish soap.

The higher rate of Indonesian unemployment than western countries has become an urgent issue that must be addressed immediately. One of the primary reasons is the entrepreneurial shortcomings of Indonesians. This study is conducted to synthetically analyze the empirical experiences of enhancing entrepreneurship in the United States as one of successful western countries. This further understanding will be transformed and applied to Indonesian universities and societies. This study uses literature analysis approaches to find references to relevant theory with the hope that researchers can in-depth understand the experiences and the significant factors facilitating entrepreneurship in the United States. At the end of the study, the authors conclude that entrepreneurship's success in the United States is due to central government support for entrepreneurship. Therefore, the success of entrepreneurship in the United States that can be applied in Indonesia, such as: (1) the Indonesian government must endeavor to oblige all universities in Indonesia to provide entrepreneurship classes, (2) promote entrepreneurship education and make entrepreneurship a priority, (3) implementing entrepreneurship in educational curricula at all levels, starting with preschool; (4) providing educational scholarship facilities for economic and business actors to become entrepreneurs, and (5) providing (people's business credit) with low interest for business.
