Abstract

This study was conducted based on a phenomenon, namely why consumers want to buy products online even though this system has several risks such as fraud by sellers, the length of time for goods to arrive and others. The purpose of this study was to determine the effect of ease of online shopping and consumer trust on online purchasing decisions in the Medan City community. This study uses a quantitative approach by collecting data through a survey method. The population used in this study were consumers who had shopped online in Medan City. This study uses a non-probability sampling technique with a stratified random sampling approach or sampling based on stratification. The sample in this study was 100 people based on the Household Analysis Unit taken from 3 sub-districts in Medan City. The data collection technique used a questionnaire that had been tested for validity and reliability. The data analysis technique used to answer the hypothesis was multiple regression. The results of this study indicate that Ease of Online Shopping has a positive and significant effect on Online Purchasing Decisions, as evidenced by the t-count value of 7.541 with a significance value of 0.000 and the regression coefficient has a positive value of 0.749. Consumer Trust has a positive and significant effect on Online Purchasing Decisions as evidenced by the t-value of 3.759 with a significance value of 0.000 and the regression coefficient has a positive value of 0.499. Ease of Online Shopping and Consumer Trust have a positive and significant effect on Online Purchasing Decisions as evidenced by the F-value of 79.765 with a significance of 0.000. The R Square value of 0.622 indicates that the ability of the independent variable to explain the variation of the dependent variable is 62.2%, and the remaining 37.8% is explained by other variables outside the research model.

Abstract

Program ini bertujuan mengoptimalkan pemeliharaan ayam kampung melalui pelatihan praktik bagi remaja panti, serta mengevaluasi dampaknya terhadap kompetensi teknis dan survival rate (SR). Kegiatan dilaksanakan dalam skema semi-intensif dengan modul inti kandang & biosekuriti, manajemen pakan & air, dan kesehatan dasar. Desain evaluasi menggunakan pendekatan pre–post pada dua luaran: (1) skor kompetensi praktik (rubrik observasi), dan (2) indikator performa pemeliharaan (SR, rata-rata pertambahan bobot harian/ADG, rasio konversi pakan/FCR, kepatuhan SOP). Data dianalisis menggunakan uji t berpasangan atau Wilcoxon, disertai effect size (Cohen’s d). Hasil menunjukkan peningkatan bermakna pada skor kompetensi peserta, diikuti perbaikan indikator pemeliharaan, khususnya SR dan kepatuhan SOP kandang. Temuan menegaskan bahwa pembelajaran berbasis praktik pada budidaya ayam kampung efektif meningkatkan keterampilan teknis remaja panti dan kinerja pemeliharaan. Implikasi praktis meliputi penyusunan SOP sederhana, jadwal monitoring mingguan, serta integrasi materi keselamatan kerja. Studi ini merekomendasikan pendampingan lanjutan untuk menjaga konsistensi praktik dan perluasan indikator ke aspek produktivitas panen dan biaya pakan.

Abstract

This study investigates the impact of service quality and trust on customer satisfaction at PT Permodalan Nasional Madani (PNM) Melati Mekar. The researchers used multiple linear regression analysis to analyze the data and tested the hypotheses using the t test and F test with the assistance of SPSS. The findings reveal that service quality has a positive and significant influence on customer satisfaction, as evidenced by the regression coefficient of 0.787 and a t value of 4.782, which is higher than the critical value. Additionally, trust also has a positive and significant impact on customer satisfaction, with a regression coefficient of 0.591 and a t value of 4.056, surpassing the critical value. Furthermore, the F test results demonstrate that customer satisfaction further improves when service quality and trust are combined, with an F count value of 11.520 that exceeds the critical value of 3.19. These results support the statement that both service quality and trust play a crucial role in enhancing customer satisfaction at PNM Melati Mekar.

Abstract

This research is motivated by business competition in the retail sector in the form of minimarkets, self-service supermarkets which is increasingly tight, making business actors flock to maintain the continuity of their companies so that they remain the choice for consumers to shop, so the role of marketing is very important. The method used in this research is quantitative. The technique used in this research is probability sampling with simple random sampling of 58 respondents. The results of data processing using the SPSS 16 program in the Coefficients table for the first regression coefficient of the service quality variable show that the calculated t value is 6,695 > t table of 2.004 so that H1 is accepted and H0 is rejected. In the Model Summary table, it can be seen that the R Square value is 0.644 or 64.4%, which means that the independent variables price and service quality influence the dependent variable of consumer decision by 64.4% and the remainder is influenced by other factors not examined in this research.

Abstract

In an increasingly competitive service market, understanding the determinants of consumer satisfaction is essential for business sustainability, especially in the beauty services sector. This study examines the impact of service quality and pricing on customer satisfaction and identifies the most significant factors at Shelly Salon MMTC. This study utilizes a quantitative methodology, including a population of 220 clients and a sample of 142 respondents selected via simple random sampling. Data were gathered by questionnaires, observations, interviews, and documentation, and analyzed employing multiple linear regression with t-tests, F-tests, and the coefficient of determination (R²). The findings demonstrate that service quality and pricing exert a positive and substantial influence on customer satisfaction (sig < 0.05). Service quality (t = 3.951) and pricing (t = 3.572) are somewhat significant influences, demonstrating notable results concurrently (F = 13.702). Service quality is the paramount variable. The Adjusted R² value of 0.153 signifies that 15.3% of customer satisfaction is elucidated by these two variables. These findings highlight the need to enhance service quality and adopt appropriate pricing strategies to increase customer satisfaction and loyalty.

Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan ketahanan ekonomi keluarga peternak pascabanjir di Kabupaten Deli Serdang melalui penerapan probiotik hemat pakan, perbaikan manajemen kandang, dan penguatan pemasaran hasil ternak. Permasalahan utama mitra meliputi tingginya biaya pakan, rendahnya penerapan sanitasi dan biosecurity kandang, keterbatasan keterampilan pengolahan pakan, serta belum optimalnya pencatatan usaha dan pemasaran. Metode pelaksanaan dilakukan melalui tahapan koordinasi awal, asesmen baseline, pelatihan, praktik pembuatan probiotik herbal fermentasi, demonstrasi penggunaan mixer pakan dan mesin peleting, pendampingan pencatatan usaha, monitoring kepatuhan SOP, serta evaluasi endline. Teknologi yang diterapkan meliputi HerbaBio-Chick, Herbal Grow Promotor, mixer pakan ternak kapasitas 200 kg, dan mesin peleting pakan. Hasil kegiatan menunjukkan bahwa program mampu memperkuat kapasitas peternak dalam memproduksi probiotik dan pakan olahan secara mandiri, meningkatkan pemahaman tentang efisiensi pakan, sanitasi, biosecurity, serta mendorong pengelolaan usaha ternak yang lebih terukur. Program ini berpotensi menjadi model pemberdayaan peternak pascabencana berbasis teknologi tepat guna dan pendampingan berkelanjutan.

Abstract

This study examines the influence of Discount Programs and Special Offers on consumer Purchasing Decisions at Matahari Department Store, Thamrin Plaza Medan. The research is important because promotional strategies are widely used in retail, yet different promotional formats may generate unequal consumer responses. A quantitative explanatory design with a cross-sectional survey approach was employed. Primary data were collected through questionnaires administered to 70 consumers selected from a population of 230 customers using incidental sampling. The data were analyzed using multiple linear regression, partial t-tests, simultaneous F-tests, and the adjusted coefficient of determination with SPSS version 16. The findings show that Discount Programs have a positive but statistically insignificant effect on Purchasing Decisions, with a regression coefficient of 0.242, a t-value of 1.698, and a significance value of 0.094. In contrast, Special Offers have a positive, significant, and dominant effect, with a coefficient of 0.686, a t-value of 5.869, and a significance value of 0.000. Simultaneously, both variables significantly affect Purchasing Decisions and explain 44.9% of their variation. These findings imply that retailers should prioritize relevant, transparent, and value-added Special Offers while using conventional discounts selectively. The originality of this study lies in revealing the differential and complementary effects of two promotional mechanisms within an offline department-store context, showing that consumers respond more strongly to additional value, urgency, and exclusivity than to price reductions alone.
