Abstract

Since the modern soil assessment focus is currently moving towards “soil health”, it is important to align the Basic Cation Saturation Ratio/BCSR of soil fertility evaluation with this term, yet no research conducted its application in tandem with CNP stoichiometries, nor vice versa. This study evaluated soil nutrient ratios across a hydrosequence transect in North Musi Rawas Regency, the lowland area of eastern Sumatra using Basic Cation Saturation Ratio/BCSR and CNP stoichiometries as potential soil health indicators. By integrating international and national/Indonesian BCSR framework and globally recognized CNP stoichiometry criteria, this study found that all soils experienced cation deficiencies, particularly in the upper soil depth (0–30 cm), alongside low phosphorus (P) and potassium (K) availabilities and their imbalances with C and N in deeper layers (30–60 cm). Cation ratios were observed to decline closer to the Merang River but increased with sampling depth. Additionally, wetter, gleyed soils exhibited greater cation imbalances while maintaining relatively balanced CNP stoichiometries. This study proposes an integrated multi-proxy approach combining BCSR and CNP stoichiometries as a cost-effective method for assessing soil fertility and health by addressing nutrient imbalances.

Abstract

Soil erosion refers to removing topsoil caused by the action of water or wind, with its intensity influenced by natural factors specific to the location. This study aims to predict soil erosion, determine tolerable erosion levels, and provide recommendations for land use based on erosion predictions in the Posigadan District, South Bolaang Mongondow Regency, North Sulawesi Province. Conducted between February and April 2024, the research employed the Universal Soil Loss Equation (USLE) method integrated with Geographic Information System (GIS) technology. The USLE method's accuracy depends on factors such as rainfall erosivity (R), soil erodibility (K), slope length and steepness (LS), vegetation cover (C), and conservation practices (P). Meanwhile, GIS proved effective in assessing erosion risks across large areas. The findings revealed that predicted erosion values ranged from 35.59 to 605.06 tonnes/ha/year, categorized from low to very high. Tolerable erosion values ranged from 2.88 to 11.00 tonnes/ha/year. Without conservation measures, areas with low actual erosion were recommended for cultivating crop such as corn and peanuts. In contrast, areas with very high erosion were better suited for plantation commodity like cloves, candlenuts, and cocoa. The study concluded that erosion predictions fell into low, medium, high, and very high categories. Based on these results, land use recommendations included food and horticultural crops for areas with low erosion and plantation crops for areas with very high erosion.

Abstract

Kubu Raya Regency is one of the areas that has a peat ecosystem in it. The peat ecosystem has a role and function in mitigating climate change because it has the ability to store quite high carbon reserves. However, peat ecosystems often experience degradation and changes in land cover which can contribute carbon emissions to the atmosphere. Remote sensing is a technology that can be used to detect changes in land cover and use in Kubu Raya Regency. Therefore, this research aims to detect changes in land cover and using remote sensing technology and assess the level of accuracy of the detection results. Analysis of changes in land cover and use from 2000 - 2023 was obtained by guided classification using the Random Forest (RF) algorithm which involves various vegetation, water and built-up land indices. The research results show that there is a decrease in forest land area from 2000 to 2023 amounting to 106,542 ha. The forest area in 2000 was 524,359 ha, while in 2023 it will be 417,817 ha. The results of accuracy measurements show an overall accuracy (OA) value of 98.84% with a kappa statistic of 0.98. It is hoped that the results of these findings will provide an initial picture of the condition of the ecosystem in Kubu Raya Regency, most of which is a peat ecosystem, as a consideration in formulating peat ecosystem conservation policies.

Abstract

Reutealis trisperma (sunan candlenuts) is a non-edible vegetable oil source that can be used as a feedstock for biodiesel production. The biodiesel production process from Reutealis trisperma seed oil involves several stages, including oil extraction, purification, as well as esterification and transesterification reactions using catalysts. This article aims to examine the technology of biodiesel production from Reutealis trisperma seeds, the challenges faced in industrial implementation, and its future development opportunities. Various oil extraction methods, such as mechanical pressing and solvent extraction are compared to determine the efficiency of crude oil conversion. Additionally, the use of heterogeneous and homogeneous catalysts in the transesterification process is analyzed to optimize biodiesel conversion. The results of the literature study conducted indicate that biodiesel from Reutealis trisperma has characteristics that comply with national and international biodiesel standards. However, there are several challenges in the production process, such as the availability of raw materials, the fatty acid content and composition of Reutealis trisperma, environmental impact, and sustainability aspects. The development of more environmentally friendly technology and the utilization of biomass waste-based catalysts present potential opportunities to enhance the sustainability of this biodiesel production.

Abstract

Streptococcus pyogenes is a bacterium that causes throat and skin infections.  Diseases caused by Streptococcus pyogenes bacteria can typically be treated with antibiotics. This study aims to determine the antibacterial activity of the ethanol extract of gaharu leaves (Aquilaria malaccensis Lamk) against the development of Streptococcus pyogenes bacteria using the disc diffusion method. The positive control used the antibiotic clindamycin, and the negative control used 1% DMSO. Observations were made by measuring the inhibition zone formed around the paper disc. The average diameter of the inhibition zone formed included a 10% concentration of 9.8 mm, a 15% concentration of 10.08 mm, a 20% concentration of 11.54 mm, and for the positive control, antibiotic clindamycin, it was 29.92 mm in the very strong category. In contrast, the negative control, 1% DMSO, did not form an inhibition zone. The One Way Anova data analysis test using the SPSS IBM version 26 program obtained results (p>0.05), meaning that there were significant antibacterial and differences in the diameter of the inhibition zone of the ethanol extract of gaharu leaves in each treatment.

Abstract

The term "organoleptic testing" is synonymous with the more specific term "sensory evaluation". The objective of the study was to ascertain the impact of incorporating supplementary yellow corn in the formulation of broiler chicken nuggets on their sensory quality and cooking loss. The research method employed was of an experimental nature, utilising a Completely Randomised Design (CRD) with three distinct treatments: P0, representing the control, P1, which involved the incorporation of 25 g of yellow corn into a 100% nugget mixture (10%), P2, encompassing the addition of 37.5 g of yellow corn into a 100% nugget mixture (15%), and P3, comprising the inclusion of 50 g of yellow corn into a 100% nugget mixture (20%). Recent studies have demonstrated that the provision of yellow corn does not exert a significant influence on the sensory quality values and cooking losses of broiler chicken nuggets (p > 0.05). The cooking loss of P1 nuggets was found to be 0.019% lower than that of P2 nuggets (0.22%) and P3 nuggets (0.41%). The Duncan test demonstrated that there was a negligible difference between P1 and P2, and between P2 and P3. Furthermore, there was no significant difference between P2 and P3. The lowest cooking loss for chicken nuggets in the treatment with the addition of yellow corn was P1 0.019%. This shows that the higher the level of yellow corn added, the lower the cooking shrinkage. The lower the cooking shrinkage value, the better the product quality because there will be less nutritional loss, on the other hand, the higher the cooking shrinkage value, the lower the product quality. The findings showed that the provision of yellow corn did not have a significant effect on the sensory quality or cooking loss of broiler chicken nuggets.

Abstract

The utilization of natural polymer-based feeding films has emerged as an alternative to plastics and as a solution to the problem of environmental pollution. Concurrently, these films maintain the function of maintaining the shelf life, quality, and safety of food products. The objective of this study was to ascertain the effect of varying proportions of whey-chia seed combinations and types of plasticiser on the physicochemical characteristics of food films. The present study employed a completely randomised factorial design, comprising Factor A: whey-chia seed combination (A1 = 1:0.5; A2 = 1:0.75 and A3 = 1:1) and Factor B: type of plasticizer (B1 = sorbitol and B2 = polyethylene glycol/PEG). The interaction between the whey-chia seed combination and the type of plasticizer did not show a significant effect (P>0.05). However, the whey-chia seed combination itself had a significant impact (P<0.01) on film elongation and tensile strength. The utilisation of sorbitol as a plasticiser resulted in enhanced flexibility of the film, thereby rendering it more appropriate for utilisation in healthy and environmentally friendly food applications. The optimal treatment was determined to be a mixture of whey-chia seeds in a 1:1 ratio with sorbitol plasticizer, yielding an elongation at break of 74.23%, tensile strength of 3.997 MPa, and crude fibre content of 15.67%.

Abstract

Long-tailed macaques (Macaca fascicularis) live in groups with a social structure consisting of many males and females (multi-male and multi-female), and interactions between individuals such as social activities are strongly influenced by hierarchy. This study aimed to determine the social hierarchy structure of adult male long-tailed macaques (M. fascicularis) and their behavioral profiles in middle area groups in the Pura Agung Pulaki, Bali. Observations were conducted using focal animal sampling and ad libitum sampling methods. The hierarchical structure was observed using three methods, namely the sociometric matrix method, food distribution, and other analyses that support hierarchical determination (non-copulatory mounting, scrotal touching, and combing between males). The highest activities in the middle area group were browsing (17.2%) and moving (17.2%). The hierarchical structure in the middle area group is ordered from the most dominant individual as follows: Ra, Co, Ma, Ku, Cha, Fra, Ka, Ni, In, and Jo. The hierarchical structure in the middle area group is linear. The provision of food bait has been proven effective in determining the social hierarchy structure in long-tailed macaques (M. fascicularis). This study can be used as a basis for the conservation of long-tailed macaques (M. fascicularis) in the Pura Agung Pulaki area.
