Islamic Business Ethics in Live Selling Practices of Halal Culinary MSMEs in Padang City

2026-07-23T09:37:03+07:00

Purpose – This study aims to analyze the implementation of Islamic business ethics in live selling practices among halal culinary MSMEs in Padang City and examine its influence on consumer trust and business sustainability.

Methodology – This study employed a qualitative approach with a case study design. Data were collected through in-depth interviews, observations, and documentation involving halal culinary MSME actors actively conducting live selling on digital platforms such as TikTok Live, Shopee Live, and Instagram Live. Data were analyzed using descriptive qualitative analysis based on the interactive model of Miles, Huberman, and Saldana.

Findings – The findings reveal that live selling has become an important digital marketing strategy for halal culinary MSMEs in Padang City. Islamic business ethics principles such as honesty, transparency, politeness, sincerity, and halal assurance were consistently implemented during live selling activities. Ethical communication positively influenced consumer trust, customer loyalty, and business sustainability. However, MSMEs also faced several challenges, including intense digital market competition, limited digital ethical literacy, and communication difficulties during live streaming interactions.

Implications – This study highlights the importance of strengthening digital ethical literacy and developing practical guidelines for sharia-based digital marketing among halal MSMEs. The findings may serve as references for policymakers, halal institutions, and educational organizations in designing ethical digital business training programs.

Originality – This study contributes to Islamic business ethics literature by specifically examining the implementation of ethical values in real-time live selling practices among halal culinary MSMEs in Padang City, an area strongly influenced by Islamic cultural values

Critical Path Method and Gantt Chart-Based Truck Fleet Scheduling at PT. Bangun Jaya Sentosa

2026-07-23T14:34:49+07:00

Purpose – This study aims to analyze and redesign truck operational scheduling at PT. Bangun Jaya Sentosa Pamekasan using the Critical Path Method (CPM) and Gantt Chart to identify critical activities, determine schedule flexibility, and reduce operational delays.

Methodology – A descriptive quantitative case study approach was applied. Data were collected through process observation, interviews with the operational manager, scheduling staff, and drivers, and documentation of historical truck-rental records.

Findings – The CPM analysis identified ten core activities with a critical path of A-B-C-D-E-G-H-J and a minimum operational cycle duration of 4,180 time units. Activities F and I were non-critical, with slack values of 360 and 320 time units.

Implications – The findings extend scheduling theory by showing how criticality and slack can be interpreted jointly with fleet-management, queueing, and service-quality mechanisms in a demand-volatile local rental setting. Practically, the proposed schedule supports lower delay risk, reduced fleet idle time, more accurate truck-availability prediction, and stronger service reliability and responsiveness.

Originality – The study converts deterministic CPM and Gantt Chart outputs into operational decision rules for urgent-order prioritization, service recovery, and vehicle-availability control under breakdown, rental-extension, and nighttime-access constraints.
