Abstract

Every student must possess problem-solving abilities. Solving students' problems is varied; several factors influence the difference between cognitive styles and learning models. This study aimed to determine differences in problem-solving abilities based on students' cognitive styles in the Concept Attention (CA) and Group Investigation (GI) learning model. This study was a quantitative study with the tenth-grade students of SMA Negeri 16 Semarang as the 2018/2019 academic year population. The sample was selected using cluster random sampling. The research data had been collected through documentation and tests and then were analyzed using nonparametric tests, specifically the Hildebrand test, since the data were not normally distributed. The results showed that students with Field Independent (FI) cognitive style's problem-solving ability were better than students with Field Dependent (FD) cognitive style, either in general, CA, or GI learning models. The CA learning model produced better problem-solving abilities than the GI learning model, both in general and in terms of the type of students’ cognitive style.

Abstract

This study aims to determine the efficiency of tall coconut (Cocos nucifera L) marketing channels in Sungai Kakap District, Kubu Raya Regency, considering that farmers in the area still face fluctuating and low selling prices. The research employed a mixed-methods approach, involving 100 respondents consisting of farmers and other marketing actors. Data were analyzed quantitatively using marketing margin, farmer’s share, and marketing efficiency methods. The results identified four distinct marketing channels. It was found that Channel I (farmer – consumer) is the most efficient, with an efficiency percentage of only 3% and providing a 100% farmer's share. Conversely, the other three channels (Channel II, III, and IV) were deemed inefficient as their efficiency percentages significantly exceeded the 50% threshold (at 97%, 177%, and 260%, respectively). The high level of inefficiency is primarily influenced by the length of the distribution chain, which automatically increases marketing costs. Nonetheless, the majority of farmer respondents (77%) prefer Channel III due to the ease of transportation. These findings conclude that a shorter marketing channel results in a larger share of the price received by the farmer.
