Abstract

The learning process is frequently carried out using the internet, as a tool for supporting the  academic activities. Self-control in internet usage is the required characteristic for student in the student-centered learning activities. However, there is a behavior called cyberslacking, or using the internet during the work time for non-work purposes (or in this context, for non-study purposes) that must be avoided because it can affect the learning outcomes and concentration during the study. The purpose of this research is to examine the effects of self control and cyber slacking to students. This study used a quantitative method, with 157 internet- active users students served as the research sample/ subjects. The cyberslacking activities were measured with by Akbulut scales, and the self control ability were measured with the Tangney scales. The sampling technique used purposive sampling and regression analysis techniques. The results showed that there was 32.2% of self-control affecting the cyberslacking behavior among students. The non-study purposes were for sharing information and shopping, that hit high score, where the male and female students had high categories in the same element. Based on the hypothesis testing results, this study's hypothesis is accepted.

Abstract

Companies that carry out production activities necessarily want the company's goals to be achieved, one of which is optimal profit. Maximum profit in production can be realized by planning the optimal amount of production. The purpose of this study consists of four, namely making a profit formulation to maximize the amount of production, determining the optimal number of brown bread variants that will be produced at Win Bakery, determining the maximum profit in producing bread at Win Bakery, and predicting profits for return on investment. This research was conducted using a linear programming model. Decision variables determine the decisions that will make to achieve the optimal solution. The objective function is a function that describes the goals or objectives in linear programming problems. Relating to the optimal use of resources to obtain maximum profit or to use minimum costs. A constraint function is a form of formulation of the obstacles faced in achieving the goal. The results obtained from the research are the decision variables, with X1 being the number of square chocolate bread productions and X2 is the number of round chocolate bread productions. The objective function of the profit per unit is to maximize Z = 1000X1 + 800X2. The constraint function is the raw material used in making chocolate bread. Furthermore, the optimization of production with POM-QM resulted in the number of square chocolate bread production of as many as 13 piecess and round chocolate bread as many as 25 piecess so that the profit gained in one day was Rp. 32,500. The next calculation, the break-even point by entering fixed costs, variable costs, and profits obtained results in units of 55 units and the total profit earned is Rp. 1,777,00.

Permasalahan pengelolaan sampah plastik dan penataan area kerja masih menjadi tantangan utama bagi UMKM kuliner, khususnya yang beroperasi di ruang terbuka. Kegiatan Pengabdian kepada Masyarakat ini bertujuan untuk meningkatkan tata kelola area produksi dan pengelolaan sampah plastik konsumen melalui penerapan Teknologi Tepat Guna berbasis metode 5R (Ringkas, Rapi, Resik, Rawat, dan Rajin) pada UMKM Ayam Bakar Solo wilayah Depok. Metode pelaksanaan dilakukan secara bertahap, meliputi observasi dan identifikasi masalah, sosialisasi 5R secara partisipatif dan aplikatif, penerapan TTG berupa tempat sampah otomatis serta pemajangan informasi visual 5R di area produksi, dan uji coba serta evaluasi tanggapan mitra. Hasil kegiatan menunjukkan adanya perbaikan pada kerapihan dan kebersihan area kerja, meningkatnya kesadaran pekerja dalam memilah dan mengelola sampah plastik, serta terbentuknya kebiasaan kerja yang lebih tertib dan disiplin. Pendekatan partisipatif membuat solusi yang diterapkan mudah dipahami dan dijalankan oleh mitra dalam aktivitas operasional sehari-hari. Kegiatan ini membuktikan bahwa penerapan 5R yang didukung oleh TTG sederhana dapat menjadi solusi efektif dan berkelanjutan bagi UMKM dalam menciptakan lingkungan kerja yang lebih bersih, efisien, dan ramah lingkungan.
