Abstract

Chocolate producers need to know and understand the tastes of the Indonesian people specifically when making decisions to purchase chocolate bars. Research on the characteristics of the types of chocolate bars that consumers like is still needed to be able to reach a wider target market. The hedonic rating test requires panelists to measure the level of liking of the sample from most liked to least liked. The majority of teenagers and adult consumers in Indonesia are involved as panelists according to demographic research on chocolate consumers. The samples tested were six brands of chocolate bars circulating on the Manokwari city market. The panelists involved were 160 consumers (67 men; 93 women, aged 13–24 years). The sensory test method used was the hedonic rating test which was presented in two variants of serving method: (1) blind test (without additional information) (2) informed test (product variants and brand information accompanied by the product in intact packaging). To identify the influence of the variant of chocolate in the sample, the Friedman test and Duncan’s advanced test were used at a significance level of 5%. To identify the effect of information, intervention using non-parametric analysis using averages with the Mann-Whitney U test was used. The results of the chocolate preference level test showed that there was a significant difference in preference of variants chocolate (at a significance level of 0.05), whereas in the information intervention test of brand and variant of chocolate, there were samples that had significant differences in preferences.

Abstract

Cocoa (Theobroma cacao L.) is a beverage crop with high economic value. Provision of natural PGR, namely red unions, which will be extracted. This study aimed to determine the effect of red onionxtract (Allium cepa L.) as a growth regulator on cocoa seeds. The research was conducted at a screen house at the Polytechnic of Agricultural Development Manokwari (Politeknik Pembangunan Pertanian Manokwari). The study method used was a completely randomized design (CRD), using five treatments and 20 replications, so the number of samples was 100 seeds. The treatments tested on cocoa plant seeds P0 (control), P1 (25% concentration of red onion extract), P2 (50% concentration of red onion extract), P3 (75% concentration of red onion extract), and P4 (100% concentration of red onion extract). The measurement variables included germination percentage, plant height, stem diameter, number of leaves, and seedling growth percentage. Differences in the concentration of growth regulators of red onion extract had a significantly different effect on seedling percentage and seed growth percentage and had a significant effect on plant height, stem diameter, and number of leaves of cocoa seedlings. Soaked cocoa seeds in red union extract with a concentration of 25% give optimum results.
