Abstract

Indonesia’s rubber plants nationally is still relatively low compared to other natural rubber-producing countries, which is 858 kg/ha/year. The lack of precision of the inefficient exploitation and tapping system implemented by rubber farmers, both community plantations, government and private, is one of the causes of low rubber production in Indonesia. This study aims to determine the influence of the production and physiology of latex in the PB 260 clone community rubber plant after being given a stimulant made of PEG 6000 and oleochemicals. The research was carried out in a community rubber plantation, located in Galang District, Deli Serdang Regency, North Sumatra Province. The altitude of the place is 25 m above sea level with the Ultisol soil type. The research began in July 2022 to November 2022. The plant material used in the field is a 20-year-old PB260 clone rubber plant. Research observations include plant production in the field on smallholder rubber plantations, as well as latex physiological analysis conducted at the Laboratory of the Faculty of Agriculture, Islamic University of North Sumatra and the Sungei Putih Research Institute, Field experiments used a three-replicate factorial group random design with PEG 6000 and Oleochemistry as treatments. The A1 treatment generally had the best effect on all the observational parameters of the study. The combination of PEG 6000 3% and Oleochemistry had an insignificant effect on latex production, rubber dryness, rubber physiology, and rubber histology. However, statistically the combination of P1A1 has a positive effect on rubber plants.

Abstract

Cyrtostachys renda has various pharmacological activities. C. renda roots contain alkaloids and flavonoids as secondary metabolites' main components responsible for anti-inflammatory and anticancer activities. To produce secondary metabolites from C. renda, tissue culture can be used through callus and cell suspension culture techniques. Browning is one of the main challenges in plant tissue culture, which inhibits the success of callus formation, especially in plants with a high content of phenolic compounds such as C. renda. This study tested the effect of soaking in polyvinylpyrrolidone (PVP) and ascorbic acid (AA) in inhibiting the browning process in C. renda explants. Explant colour change testing was done in vitro by soaking the explants in five concentrations of PVP and AA (50, 100, 150, 200 and 250 ppm). Changes in explant colour were then analyzed using the Royal Horticultural Society (RHS) colour chart. The results showed that the PVP antioxidant with a concentration of 200 ppm could suppress explant browning until the fourth day. In comparison, explants treated with AA antioxidants with a concentration of 200 ppm showed browning symptoms on the second day. It can be concluded that antioxidants can reduce the browning level in C. renda shoot explants, and the antioxidant PVP can reduce the browning level better than AA. The mechanism of PVP as an anti-browning agent through inhibition of phenolic oxidation. This study's novelty is obtaining the type of anti-browning PVP with an optimum concentration of 200 ppm to inhibit the browning of C. renda shoot explants.

Abstract

The issue of poverty and food and nutritional vulnerability in the Suku Anak Dalam (SAD) community in Bukit Duabelas National Park requires special attention. This study will integrate various assets owned by indigenous communities, including local wisdom and social capital, with opportunities to develop the potential of natural resources in TNBD to support the achievement of SDGs. This research aims to describe the picture of SAD livelihoods and their changes and design a design or pattern for sustainable SAD livelihood development. The research uses a constructivist paradigm with a case study approach. Data analysis uses the Sustainable Livelihoods Framework to identify and evaluate SAD individuals or communities' assets, capacities, and strategies for maintaining sustainable livelihoods. The results of this research show that, SAD communities in TNBD still depend on extractive agriculture, such as hunting and gathering, but are starting to switch to plantation cultivation, such as oil palm and rubber. Professions outside the agricultural sector are limited, and their access to formal employment is hampered by limited education and skills. SAD has a variety of assets, including human, natural, social, financial, and physical capital. Social and natural capital are their main assets. Despite limited education, their natural resources are sufficient to support life. To increase SAD's livelihood sources, interventions such as utilizing mapped site space, piloting productive site projects, strengthening cooperation between government, NGOs and the private sector, and community-based sustainable forest management are needed.

Abstract

Dynamic thinking is a crucial cognitive skill that enables students to solve complex problems in geometry effectively. This study investigates the characteristics of dynamic thinking among prospective mathematics teachers, focusing on the four key aspects: technique, conceptualization, monitoring, and perception. While previous research has identified these aspects, the specific problem-solving characteristics of dynamic thinking in mathematical contexts remain unexplored. This qualitative study was conducted at Tidar University, involving 54 prospective mathematics teachers identified as dynamic thinkers. Data were collected through a two-stage problem-solving test, structured observations, and in-depth interviews. The research instruments underwent a validation process to ensure reliability. Data analysis followed a systematic approach involving reduction, presentation, and verification to extract patterns of dynamic thinking among proficient problem solvers. The results indicate that students who exhibit proficient dynamic thinking demonstrate completeness and consistency in all four aspects. They effectively integrate multiple strategies, adapt their approaches in response to challenges, and maintain a reflective understanding of their problem-solving processes. Additionally, proficient dynamic thinkers show a higher degree of flexibility and spatial reasoning in geometry problems. This study contributes to the existing body of knowledge by identifying and describing the specific characteristics of dynamic thinking in mathematical problem-solving. The findings provide valuable insights for teacher education programs, emphasizing the need to cultivate dynamic thinking skills among prospective math educators. Future research can explore dynamic thinking across different mathematical domains and cognitive frameworks.

This is a study on the evaluation of material damping ratios obtained from experimental data and laboratory tests, an essential criterion to reproduce reality in virtual simulations done for our computational models. The methodology involves iteratively seeking optimal solutions through multiple simulations, providing a way to estimate dynamic responses accurately. The article concludes by emphasizing the importance of numerical-stepping methods in tackling challenging problems in dynamic response analysis. It highlights the significance of numerical-stepping methods for handling non-linear systems and time-varying excitations in dynamic response analysis. This research addresses fundamental issues in the context of applied mechanics. In particular, the article is intended to provide a few computational algorithms where respective graphs are generated, depicting the relationship between time and displacement. Some highly efficient numerical procedures can be developed for linear systems by interpolating the excitation over each time interval and developing the exact solution using a variety of five methods. The numerical results obtained are compared with the theoretical solution. Our research manages to evaluate the depreciation of the material through the models reviewed in the article and gives the results according to the applied models by comparing the results and calculating the absolute error.
