Abstract

The source of raw materials and the fermentation process carried out really need to be considered when processing it into chocolate bar products. This research aimed to determine the effect of seed origin and fermentation treatment on product quality and quality. The treatments in this research were cocoa beans from Soppeng Regency (South Sulawesi) and Polman Regency (West Sulawesi) with differences in fermentation time, namely 5 days and 7 days. The research results show that the raw material for cocoa beans used in making processed chocolate bars is influenced by the origin of the beans and the fermentation treatment. Visual test results showed that there was no difference in results for seeds from Soppeng and Polman. The processed product is brown in color and has a distinctive aroma because it comes from fermented cocoa beans. Testing for water content and fat content is greatly influenced by the fermentation process where a good stirring process during the fermentation process can increase the fat content and reduce the water content. Test results for metal contamination: Lead <0.0134, Cadmium <0.0013, Tin <0.0776, Mercury and Arsenic <0.0002. The results of microbial testing were TPC 1.2 x 101 and 7.0 x 101 colonies/g, Escherichia coli <3, Mold and Yeast 1.3 x 102 and 7.0 x 101 colonies/g and Salmonella was negative. The results of testing for metal contamination and microbiology show that processed cocoa products (chocolate bars) at the Politani Pangkep cocoa processing workshop are safe for consumption because they have test results below the SNI reference value.

Abstract

The rapid expansion of Facebook Marketplace has redefined the landscape of digital commerce in Indonesia, serving as a low-barrier platform that facilitates informal buying and selling activities. In the context of increasing internet penetration and the widespread adoption of online shopping—exacerbated by the COVID-19 pandemic—this platform has become an essential medium for everyday economic transactions. This study explores the dynamics of negotiation and communicative behavior among Indonesian users of Facebook Marketplace, with particular attention to broader shifts in consumer interaction patterns within digital environments. Employing a qualitative, phenomenological methodology, this research focuses on the lived experiences of two experienced users selected through purposive sampling. Data were gathered via in-depth interviews and naturalistic observation, and analyzed through the stages of data reduction, data display, and conclusion drawing, following the analytical framework of Miles and Huberman. The findings indicate that negotiation practices on Facebook Marketplace constitute strategic and performative acts, heavily influenced by users’ digital literacy, impression management strategies, and responsiveness to social cues. Informants engaged in storytelling, employed multiple accounts, utilized emotional appeals, and adopted persuasive linguistic techniques to shape negotiation outcomes. These practices are interpreted through Goffman’s dramaturgical theory, wherein interactions are seen as performances alternating between front-stage and back-stage behavior. Despite the absence of physical presence, users rely on digital semiotics—such as emojis, tone modulation in text, and contextual signaling—to convey intentions and cultivate trust. This research contributes to the understanding of digital negotiation in Southeast Asian social commerce contexts, highlighting the ways in which platforms like Facebook Marketplace foster novel forms of economic participation, digital communication, and self-presentation.
