Abstract

The avocado (Persea americana), a recognized superfood and valuable horticultural commodity, exhibits significant morphological diversity due to long-term adaptation to various habitats, enhancing biodiversity. This study analyzed the diversity and genetic relationships of cultivated avocados in Gorontalo Regency. Using the Descriptors for Avocado (Persea spp.), 25 qualitative morphological traits were characterized, and a phenetic analysis of 17 accessions was conducted using UPGMA with Jaccard’s Coefficient. Accessions were collected from six villages across four sub-districts: Dulamayo Barat, Dumati, Hepuhulawa, Kayubulan, Kayumerah, and Tridarma. Results revealed substantial diversity in traits such as tree shape, and the morphology of stems, leaves, fruits, and seeds. Phenetic analysis grouped the accessions into two clades: Clade A, comprising 15 accessions in two clusters (similarity index: 64.7-29.0%), and Clade B, containing two accessions in one cluster (similarity index: 64.7%). Clades A and B exhibited a distant relationship, with a similarity index of 23.6%. Conserving the diverse avocado germplasm is essential for safeguarding genetic resources and supporting breeding programs to develop superior varieties in Gorontalo

Abstract

This study aims to determine the effectiveness of the application of the Problem Based Learning model to improve students' critical thinking skills on the human digestive system material of class XI of SMA Negeri 1 Moutong. The study used a pre-experimental design method with a one group pretest-posttest design approach involving 25 students of class XI IPA2. The research instruments included critical thinking tests (pretest and posttest), learning implementation sheets, student activity sheets, and student response questionnaires. The results showed that the learning implementation reached an average of 94% with the category (very good), student activity 94% (very good), and student response 91% (very positive). The average pretest score of 42.2 increased to 79.2 in the posttest with an N-Gain value of 0.59 (moderate category). Significant improvements occurred in the indicators of providing simple explanations and organizing strategies or actions, increasing from 34.4% and 32% to 92%, respectively. These results indicate that the implementation of the PBL model is effective in improving students' critical thinking skills in the human digestive system.
