Abstract

Bituminous and Anthracite are coal mined in Indonesia. The use of this energy becomes very elementary for various purposes or energy needs. Therefore, its distribution is a problem in itself because it crosses various mediums, be it river flows and also road sections in Batanghari district. Problems that arise in connection with the transport system studied in this study are those that pass through the highway, so that aspects of the road class and the load of the transport fleet need to pay attention to the regulations set by the government, both central and regional. This research is an empirical study with a qualitative approach that aims to obtain actual answers regarding the coal transportation system with land transport modes, namely trucks with various carrying capacities. Data was obtained by observation along the road route passed by coal trucks. In addition, data was also obtained from sources of legislation regarding the public transport system issued by the central and regional governments. The data was analysed by looking for highlights of reality, then elaborated with juridical guidelines and other legal facts. The results of the study found that the Implementation of Jambi Province Regional Regulation Number 13 of 2012 concerning Coal Transportation Regulations in Batanghari has not been running properly, there are still many rules that are violated by Coal entrepreneurs this is because the government seems to relax existing regulations. Problems experienced by the government are obstacles in making special Coal transport routes.

Abstract

Chitosan, a natural polysaccharide obtained through the deacetylation of chitin, exhibits unique properties that make it a potential material for various applications, including agriculture. This study aims to examine the characteristics of chitosan derived from Black Soldier Fly (BSF) pupa shells and its role as a crosslinking agent in polymer-based hydrogel synthesis for slow-release fertilizers. Chitosan was isolated through chemical processes, including demineralization, deproteinization, and deacetylation. Characterization was conducted using FTIR, XRD, SEM, TEM, and TGA. The results revealed that chitosan from BSF pupa shells has a degree of deacetylation of 83%, a semi-crystalline and slightly amorphous structure, pores that enhance water absorption capacity, and high thermal stability. These properties make chitosan an effective crosslinking agent, improving hydrogel stability and extending nutrient release duration. These findings demonstrate the potential of chitosan as an innovative material for hydrogel applications in sustainable agriculture.

Abstract

Antioxidants play a role in preventing and repairing damage to human cells. Searches for antioxidant sources continue to be carried out including in P. subpeltatum plants. This study aims to compare the antioxidant activity of the bark, wood, and leaves of P. subpeltatum C.B. Rob plants. The materials were dried and then shaved to a fineness level of 80 mesh. Materials were extracted using the maceration method with ethanol solvent. The macerate was filtered and the filtrate obtained was concentrated with an evaporator. The three extracts were tested for antioxidants using the DPPH (1,1-diphenyl-2-picrylhydrazyl) Free radical scavengers method, ascorbic acid was used as a comparison. Absorbances was measured using UV-Vis spectroscopy. Each material was made in 5 concentrations. The IC50 value was calculated using the Blois regression equation. The results of the antioxidant test were obtained consecutively: stem wood with an IC50 value = 3.39 μg/mL, stem bark = 5.15 μg/mL, and leaf = 258.58 μg/mL, the IC50 value of ascorbic acid was 2.79 μg/mL. Based on these data, it shows that the antioxidant activity of stem wood and stem bark is in the high category, although still lower than ascorbic acid, while the leaf are included in the weak category.
