INSTITUTION ANALYSIS OF FARMERS GROUP HOLDERS OF SOCIAL FORESTRY LICENSE IN THE FOREST MANAGEMENT UNIT OF BATUTEGI, INDONESIA
Full text linkInstitutions are the rules of the game that can regulate the activities of Farmers Group members to support Social Forestry activities. The study aimed to analyze the structure, roles, and institutional rules of the Farmers Group of Karya Tani Mandiri and the Farmers Group of Karya Bakti in the Forest Management Unit of Batutegi, Indonesia. Data collection was carried out using interviews, observations, and literature studies. The data that has been collected is then analyzed using a Likert scale. The results showed that Farmers Group of Karya Bakti in terms of structure, roles, and complete game rules compared to Farmers Group Karya Tani Mandiri. This is because the Farmers Group of Karya Tani Mandiri at the time in the field did not have Memorandum of Association/Article of Association, Decree of the Regent, institution’s structure, the role of the structure, but the facts in the field Farmers Group of Karya Bakti violated the rules of the game in the Memorandum of Association/Article of Association, namely cutting down trees for personal gain. In forest areas, the application of the game rules to the institution's performance of the Farmers Group of Karya Tani Mandiri and the Farmers Group of Karya Bakti needs to be improved so that forest management can be sustainable by understanding and obeying the rules of the game that apply
DNA EXTRACTION FROM LOCAL SOUVENIR OF SUKU ANAK DALAM JAMBI WITHOUT LIQUID NITROGEN USING CTAB METHOD
Full text linkOne of the local souvenirs from Jambi is accessories made from the seed bark of the sebalik sumpah tree. The sebalik sumpah tree is currently quite rare. Through DNA isolation, sebalik sumpah is one of the efforts of genetic conservation and as a first step in cultivating sebalik sumpah trees. DNA isolation is the initial stage in molecular analysis. The purpose of DNA isolation is to obtain genomic DNA from a sample. Plant DNA isolation generally uses fresh plant samples, with young and soft plant parts. This is recommended to obtain good quality genomic DNA. However, with the limitations of fresh samples, a method is needed that is able to extract DNA from plants that have changed shape and have undergone processing. Each plant requires a different method to obtain DNA. The CTAB (Cethyl Trimethyl Ammonium Bromide) buffer method is a method commonly used in plants because it is able to extract DNA with high polysaccharide and phenol content, so many have modified the method. This study aims to determine the success of the CTAB method without nitrogen in extracting processed materials and the length of incubation time at the precipitation stage. Extraction was carried out by liquid nitrogenless CTAB method with the addition of PVP (Polyvinylpolypyrrolidone). The results show that the CTAB method without liquid nitrogen is able to extract plant samples that have undergone processing and the length of incubation time at the precipitation stage affects the DNA produced.

JUNGLE RUBBER AND PIONEER TREE: INVESTIGATING LEAF MORPHOLOGICAL VARIATION OF Alstonia scholaris R. BR. IN JAMBI
Full text linkHuman activity has reduced natural forests in Indonesia and triggered their transformation into, for example, jungle rubber land, as is often found in the Jambi Province of Central Sumatera. Forming jungle rubber through successional processes involves important pioneer trees such as Alstonia scholaris. The pioneer species' performance is influenced by site factors, the initial biodiversity status, cultivation treatment, and management inputs. The study reported here was conducted to assess leaf morphological variation of A. scholaris as preliminary indicators of difference in response and growth performance in several CRC990 plots (50 m x 50 m) of two distinct landscapes: Bukit Dua Belas National Park and Harapan Rain Forest. Results of the analysis of variance showed that the difference in landscapes gave rise to a significant effect on leaf morphology variable NV (venation number) for A. scholaris. Differences between plots within the landscapes were significant in the variables venation number (NV) and petiole ratio (PR) for A. Scholaris. The results of the distribution of leaf morphological variation in A. scholaris based on multivariate analyses (PCA) showed no clustering due to landscape effects
THE MOVEMENT PATTERN AND HOME RANGE OF SUMATRAN ELEPHANTS (Elephas maximus ssp. sumatranus) IN THE LANDSCAPE OF MILA-TANGSE IN PIDIE REGENCY, ACEH
Full text linkThe Sumatran elephant is the largest mammal species on the island of Sumatera. They are listed by the IUCN as critically endangered (IUCN, 2020). The current population throughout Sumatera lies on 22 home ranges and most of them are in critical condition (KLHK, 2020). One of the home ranges in Aceh Province is in the landscape of Mila-Tange, Pidie Regency. This landscape is a meeting point among the elephant herds. The herds that have been separated into small groups will gather with the other groups in several months. This phenomenon becoming one of the triggers for the incidents of human-elephant conflict. The conservation activity is being implemented by taking into account the needs of livelihood in the area. Therefore, the research was conducted to recognize the movement pattern and its range in this landscape during period of January to December 2021. The results show that the elephant herd range lies from 123 km2 to 413 km2. The movement patterns are concentrating in the type of shrubs (1.227 points which equal to 46.73%) and mixed dry land agriculture (923 points which equal to 35.15%). The roaming area and movement patterns are mostly influenced by the environmental factors including natural food, land cover and anthropogenic activities
