Abstract

This study aims to improve students' literacy on greenhouse gas mitigation through a biochar-making project from school organic waste. This study uses a qualitative descriptive approach with a project-based learning model. The study was conducted at SMP Negeri 7 Muaro Jambi with 30 class VII G students as subjects. Data were obtained through observation, interviews, questionnaires, and documentation. The project was carried out by actively involving students in the biochar-making process, starting from waste collection, the pyrolysis process, to analyzing the benefits of biochar. The results showed that student involvement in the project significantly increased their understanding of greenhouse gases, their impacts, and mitigation solutions through biochar. Students were able to explain the concept of GHG, mention its negative impacts, understand the biochar-making process, and demonstrate an attitude of caring for the environment. In addition, teachers responded positively to the project and planned to integrate it into P5RA activities. Thus, the biochar production project has proven to be an effective method in improving students' literacy on GHG mitigation and can be used as an alternative for contextual learning based on the environment in schools.

Abstract

This study aims to determine the effect of scion length on the success of cocoa top grafting, the effect of the number of scion buds on grafting success, and the effect of shallot extract on the success of cocoa top grafting. Data collection in this study was carried out using a Randomized Block Design (RBD) with 7 treatments and 4 replications. The data samples were analyzed using Analysis of Variance (ANOVA), followed by the Honestly Significant Difference (HSD) test. The HSD test was conducted to determine which treatment means were significantly different and which were not. It was found that treatment P3 involving 4 scion buds and 300 ml/liter of shallot extract resulted in the highest survival rate of 100% and produced optimal growth responses across all observed parameters, including shoot length, number of leaves, growth rate, and stem diameter (both upper and lower stem). The effects of scion length and the application of growth regulators (PGR) from shallot extract on the parameters of shoot length and stem diameter (upper and lower) did not show significant differences, while the number of leaves and growth rate parameters showed significant effects. The treatment that produced the highest survival rate of 100% and showed optimal growth responses across all observed parameters was the treatment with 4 scion buds and 300 ml/liter of shallot extract (Treatment P3).

Abstract

This study aims to analyze the phylogenetic relationships among six species of fiddler crabs (Uca spp.) found in Lalombi Village, Banawa Selatan Subdistrict, Donggala Regency, based on morphological characters. A descriptive-exploratory approach was employed, with purposive sampling to select representative specimens. Eighteen morphometric characters were measured from three individuals of each species: U. triangularis, U. perplexa, U. dussumieri, U. annulipes, U. tetragonon, and U. bellator. Data were analyzed using Principal Component Analysis (PCA) and UPGMA clustering with the aid of PAST software version 4.03. The PCA results revealed that carapace length (CL), anterior carapace width (ACW), and posterior carapace width (PCW) contributed significantly to total morphological variation. Cluster analysis indicated a close phylogenetic relationship between U. tetragonon and U. triangularis, as well as between U. perplexa and U. bellator. U. annulipes appeared intermediate between the two groups, suggesting a moderate level of relatedness. In contrast, U. dussumieri formed a distinct branch, likely due to its markedly larger body size compared to the other species. These findings affirm that morphometric characters are valuable in elucidating phylogenetic relationships within the genus Uca and support taxonomy based on morphological traits.
