Abstract

This study investigates the effects of the marketing mix dimensions, namely product, price, promotion, and place, on purchase decisions and customer satisfaction. A quantitative research approach was employed using a survey method, involving Generation Z iPhone consumers residing in the Greater Jakarta metropolitan area, Indonesia. Respondents were selected using non-probability purposive sampling, with the principal inclusion criteria being individuals born between 1997 and 2012, residing in Greater Jakarta, and having purchased an iPhone at least once. The study involved 225 respondents. The collected data were analyzed using multiple linear regression with IBM SPSS version 27 to examine the influence of each independent variable on purchase decisions and customer satisfaction. The findings indicate that product, price, promotion, and place have positive and significant effects on customer satisfaction. However, with respect to purchase decisions, only product and price exhibit positive and significant effects, whereas promotion and place do not significantly influence consumers' purchase decisions. Product emerges as the most influential determinant of customer satisfaction and also exerts the strongest influence on purchase decisions among all independent variables. These findings suggest that product quality and appropriate pricing constitute the primary considerations influencing consumers' satisfaction and purchasing decisions. Accordingly, firms should prioritize product value and appropriate pricing while strategically utilizing promotion and distribution to strengthen customer satisfaction.

Abstract

Waste management is a major challenge for the DKI Jakarta Provincial Government, marked by daily waste generation reaching approximately 7,500-8,000 tons and a national waste-handling rate that has never exceeded 49 percent. To address this issue, the Governor of DKI Jakarta issued Governor Instruction Number 5 of 2026 concerning the Movement for Waste Sorting and Processing at the Source, which took effect on 10 May 2026 and obliges residents to sort waste into four categories: organic, inorganic, hazardous and toxic materials (B3), and residue. This community service activity was carried out in collaboration with five higher education institutions in Sukabumi Selatan Sub-district, Kebon Jeruk, West Jakarta, on 27 July 2026, with the theme of community empowerment in sustainable waste management through source-based sorting education and strengthening waste bank governance. Field observation found that only one active neighbourhood-level (RW) waste bank existed in Sukabumi Selatan. Through the collaborative competence of Management, Media Design, International Marketing, and Media Production study programs, this activity produced a joint commitment among the Sub-district Government, PKK cadres, and Karang Taruna to establish a waste bank in each RW, mentored by the respective RW's Karang Taruna unit. The activity is expected to accelerate the achievement of the RPJMN's target of 100 percent managed waste by 2029 while strengthening the local circular economy.
