Abstract

 The purpose of this study is to determine the effect of price and product quality on purchasing decisions for Huawei smartphones at Erafone Jombang Sudimara Branch in South Tangerang City partially and simultaneously. The research method used is quantitative. In this study, the consumers of Erafone Jombang Sudimara Branch in South Tangerang City were 932 people and the sample determination used probability sampling with the 10% slovin formula, so a sample of 90 respondents was obtained. Data analysis used validity tests, reliability tests, classical assumption tests, regression analysis, correlation coefficient analysis, determination coefficient analysis and hypothesis testing. The results of the calculation of the t-test value were 7.640 and a significance of 0.000 <0.05. then Ha was accepted and H0 was rejected, it can be stated that price (X1) has a significant effect on purchasing decisions (Y). The results of the calculation of the t-test value were 8.985 and a significance of 0.000 <0.05. then Ha was accepted and H0 was rejected, it can be stated that product quality (X2) has a significant effect on purchasing decisions (Y). Multiple linear regression analysis Y = 13,865 + 0.373 X1 + 0.373 X2, Based on the results of the study, it was found that the correlation value of the price variable (X1) and product quality (X2) was 0.772, meaning it had a strong level of relationship. Based on the R Square value of 0.772, this shows that 100% - 77.2%. the remainder is 22.8%. Based on the results of the analysis, namely the ANOVA test, the F count value was 64,089 while the F table (0.05) for n = 87 was 2.71. So F count> from F table (0.05) or 64,089> 2.71, with a significant level of 0.000 because 0.000 <0.05, it can be said that price (X1), product quality (X2) positively and significantly influence purchasing decisions (Y)..

Abstract

UD. XYZ is a Small and Medium Enterprise (SME) focused on bread production. During its production process, it encounters various challenges such as changes in raw material prices, problems in the dough fermentation process, delays in supplier deliveries, and an expiry rate of 8-18% per month. Specifically, a two-part House of Risk (HOR) model and a Supply Chain Operations Reference (SCOR) model are used. First, the SCOR model is used to map the processes in the bakery product supply chain. This data is then loaded into the first stage of the HOR. The next step is to determine the ARP value after evaluating the severity and frequency of incidents. Strategies to manage or mitigate risks are developed using the HOR in the second stage. Twenty risk events and nineteen risk agents were identified at UD. XYZ, with ten priority risk agents identified using a Pareto diagram and mitigation techniques developed. To reduce the likelihood of risk agents appearing in the organization, the second stage of the HOR includes sixteen suggested management tactics.

Abstract

This study aims to do the planning of raw material inventory at optimal Tire Retreading industry with Silver Meal Heuristic methods optimally. Planning includes penentian safety stock,, reorder point and Economic Order Quantity and Total Cost of Inventory. The results were obtained 706.44 kg of safety stock, reorder point 2283.76 kg and 8356 kg economic order quantity and lead time of 5 days for a total of Rp. 4,020,778,592.6. While based on the existing condition of the total cost of raw material inventory Rp. 4,061,927,100. This shows the efficiency of Rp. 41,148,507.4 or 1.01% per year.

Abstract

Pabrik gula merupakan industri manufaktur yang beroperasi secara kontinu sehingga menerapkan sistem kerja shift untuk menjaga kelancaran proses produksi. Penerapan shift kerja, khususnya shift pagi, sore, dan malam, berpotensi menimbulkan perbedaan tingkat beban kerja yang dirasakan oleh karyawan. Beban kerja yang tidak seimbang dapat berdampak pada menurunnya kinerja, meningkatnya kelelahan, serta risiko kesalahan kerja. Penelitian ini bertujuan untuk menganalisis pengaruh shift kerja terhadap beban kerja karyawan di PT. XYZ serta memberikan solusi perbaikan. Metode yang digunakan dalam penelitian ini adalah pengukuran beban kerja menggunakan NASA-TLX (Task Load Index) dengan pengujian normalitas data dan pengujian Anova menggunakan aplikasi SPSS IBM Stastistic 25. Hasil perhitungan NASA-TLX menunjukkan bahwa skor rata-rata beban kerja karyawan shift pagi sebesar 70,64 dengan tingkat beban kerja yang tinggi dan skor rata-rata beban kerja karyawan shift sore sebesar 78,73 dengan tingkat beban kerja yang sedang dan skor rata-rata beban kerja karyawan shift malam sebesar 80,82 dengan tingkat beban kerja yang sedang, pengujian menunjukan bahwa uji normalitas data dianggap normal karena nilai shift sig > 0,05, dilanjutkan dengan uji Anova dianggap signifikan karena nilai sig < 0,05 yang artinya terdapat perbedaan yang signifikan. Sehingga diperlukan usulan perbaikan dengan menerapan sistem shift yang baru, pembangunan fasilitas dan prasarana pendukung, dan memberikan pelatihan kesehatan kerja yang rutin, sehingga dapat meminimasi beban kerja karyawan dan bisa dapat meningkatkan kinerja karyawan.

Abstract

The prevalence of adolescent malnutrition in Indonesia is still high, namely stunting (23,7-24,1%), overweight/obesity (12,1-16,2%), and anemia (16,2%). One contributing factor is the consumption of unhealthy foods. This study aimed to develop a multigrain snack bar by adding tempeh flour and Spirulina, which provide protein, iron, and fiber, to prevent malnutrition. This study was conducted from March to May 2025 using a completely randomized design with tempeh flour and spirulina powder proportions of 95:5 (F1), 90:10 (F2), and 85:15 (F3). The product formulation was performed at the Nutrition Laboratory of Universitas Muhammadiyah Cirebon, Cirebon. The analysis included organoleptic (30 panelists), nutritional content, formula selection, and nutritional contribution analyses. Data were analyzed using ANOVA with Duncan’s test. There were significant differences in color, aroma, taste, overall, ash, fat, protein, carbohydrate, and iron content among the formulations (p<0.05). F1 was the optimal formulation, with 17,63% protein, 3,24 mg/100 g iron, and 3,86% fiber. One serving (20 g) contributed 4-5% of the energy requirement for adolescents (13-18 years). In conclusion, F1 was the most preferred and provided essential nutrients to meet the needs of adolescents. This study is novel in that it develops a product from tempeh and Spirulina as a potential innovative solution to address nutritional problems in adolescents.

Abstract

Adara Bakery and Cake is one of micro small and medium enterprises that focus on bread production. The problem faced by Adara Bakery and Cake is an excess of products due to a production system that uses a continuous process method, which means that bread is produced continuously without considering the products sold. The objective of this study is to determine the optimal production quantity for the 8 most popular types of bread to be produced by Adara Bakery and Cake, as well as to identify the expected profits when production is at the optimal level. This study discusses the optimal production of the 8 most popular types of bread, namely chocolate brownies, pineapple roll cake, chocolate-topped bread, chocolate banana, black forest cake, slice cake, peanut pie, and dessert, using the newsboy problem method. Based on the research results, the optimal production quantity for chocolate brownies is 141 boxes, for pineapple roll cake is 191 boxes, for chocolate bread is 351 packages, for chocolate banana bread is 335 packages, for Black Forest cake is 237 boxes, for slice cake is 239 pieces, for peanut pie is 1, 779 pieces, and for desserts is 159 pieces. The expected profit for chocolate brownies is Rp 1,252,000, for pineapple roll cake is Rp 1,494,900, chocolate bread is Rp 595, 800, chocolate banana is Rp 532,000, Black Forest cake is Rp 3,890,000, sliced cake is Rp 535,500, peanut pie is Rp 2,538,200, and dessert is Rp 1,141,000.
