Abstract

The Nyaru Menteng Arboretum area in Central Kalimantan serves as a habitat for approximately 200 Long-Tailed Macaques Macaca fascicularis within its 65.2-hectare area, as recorded in 2024. A lack of food causes presumed M. fascicularis to descend to settlements in search of food, resulting in losses for the people of Nyaru Menteng Arboretum which leads to coexistence. This study aims to identify the types of coexistences that occur between M. fascicularis and villagers. The method used to identify coexistences is a survey method. The survey results explain that the types of coexistences that occur range from stealing side dishes (25%), damaging ceilings (25%) and messing up the kitchen (50%). Human resistance in the form of repellent using slingshots 32%, wood 40%, nets 20% and air rifles 8%. The findings of this study can serve as a reference for managing future coexistences and inform decision-making for effective M. fascicularis management in the Menteng Arboretum Area, Central Kalimantan.   Keywords: Endangered, Indonesian Borneo, interaction, Long-Tailed Monkey, Macaca fascicularis.

Abstract

Ramin (Gonystylus bancanus (Miq) Kurz) is a peat swamp plant with commercial value in both national and international markets. However, the existence of ramin is threatened with extinction, due to the imbalance between regrowth and utilization, making it increasingly difficult to obtain ramin seedlings naturally. One of the efforts to propagate ramin is by cuttings. This study aimed to determine the optimum concentration of IBA (Indole Butyric Acid) growth regulator used in supporting the growth of ramin cuttings. The research method used a Randomized Group Design (RGD) consisting of 4 treatments and 6 replicates. The treatment consisted of P0 (control/0 ppm), P1 (IBA concentration 1000 ppm), and P3 (IBA concentration 1500 ppm). The data were analyzed descriptively qualitatively. The results showed that the provision of IBA affects the growth of ramin cuttings. Based on the percentage of cuttings that successfully grew, P0 successfully grew by 50%, P1 successfully grew by 83.33%, P2 successfully grew by 100% and P3 successfully grew by 100%. The average number of shoots of ramin cuttings that successfully grew in the treatment of P0 amounted to 0, P1 treatment amounted to 1, then P2 amounted to 2, and the highest number of shoots was in the treatment of P3 with 3 shoots. It can be concluded that the concentration of IBA 2000 ppm gives the best results when compared to other concentrations based on the percentage of cuttings that managed to grow and the average number of shoots.

Abstract

This community service activity aims to improve the understanding of ecosystem concepts, improve practical skills, and technological literacy of students at SMA Negeri 2 Kahayan Tengah through socialization and training in making environmentally-based terrariums innovated by Internet of Things (IoT) technology. The implementation method includes preparation, training, mentoring, monitoring, and evaluation involving 25 students and 5 teachers. Data was obtained through activity documentation, pre-post tests and student response questionnaires. The results of the activity showed a significant increase in student knowledge with an average pre-test score of 50.83 increasing to 82.40 in the post-test, achieving an N-Gain of 0.61 categorized as medium. Student responses were also highly positive, with 85% rating the activity as engaging, 82% reporting increased environmental awareness, 75% feeling more motivated to learn science, and 80% considering the program relevant to the Merdeka Curriculum. The terrarium products created by students reflected creativity and potential to be further developed as both innovative learning media and marketable products. This program contributes to the implementation of the Projek Penguatan Profil Pelajar Pancasila (P5) while introducing IoT applications as an innovation in environment-based education.
