Published: March 2024

The biosorption of crude-oil spill using acetylated and unacetylated Cissus populnea leave, stem and root biosorbents was investigated in this study. The acetylated and unacetylated biosorbents was characterized by Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM). The FTIR spectra confirmed the formation of the acetyl group while SEM morphological analysis of acetylated biosorbent showed rough macrostructure surfaces with large hollows between the strand. The effectiveness of the biosorbents was evaluated based on their ability to remove crude oil from an aqueous solution. The results sho wed that the acetylated biosorbents had higher oil sorption capacities compared to the unacetylated biosorbents. The highest oil sorption capacity was observed for the acetylated stem biosorbent, which had a sorption capacity of 30.09 g/g. The unacetylated leaves biosorbent had the lowest oil sorption capacity, with a sorption capacity of 20.4 g/g. The leaves and roots biosorbents showed intermediate oil sorption capacities. The study also showed that the biosorption capacity of the biosorbents increased with increasing initial oil concentration and contact time, while decreasing with increasing biosorbent particle size. The results suggest that acetylated Cissus populnea biosorbents have potential as an effective and low-cost alternative for the remediation of crude-oil spills.

This research addresses the prevalence of arthritis in Indonesia, focusing on traditional medicinal plants like Ciplukan due to the side effects of synthetic treatments. Arthritis, affecting 23.6-31.3% of the population, with Osteoarthritis (50-60% in the elderly) being the most common, necessitates alternative, less toxic remedies. Traditional medicine, relying on plant-derived remedies, is explored for its accessibility, affordability, and lower side effects. The study delves into Ciplukan, known for its anti-arthritis properties, conducting in vitro tests on its methanol extract. Results reveal anti-arthritis activity attributed to steroids, flavonoids, and alkaloids. The methodology involves macroscopic and microscopic examinations of Ciplukan plants, verifying authenticity and confirming the accuracy of plant samples. Organoleptic assessments highlight distinctive features, contributing to the plant's identification. Microscopic examination reveals the presence of stomata and palisade cells in the upper epidermis, aligning with literature data. The vascular system analysis emphasizes the efficiency of resource transport and adaptation to environmental changes. In conclusion, the study provides a comprehensive understanding of Ciplukan's characteristics, supporting its potential in arthritis treatment. The findings contribute to the utilization of traditional medicine in healthcare, emphasizing the importance of plant-based remedies with fewer side effects.

Dryland management with an agroforestry system is essential and urgent. Currently, the existence of forests has experienced pressure on forest areas and forest resources, which threatens the integrity of forest areas due to the increase in land area, which is categorized as dry. This research aims to determine the size of ​​dry land and the dominant factors that drive the damage rate. This research aims to analyze agroforestry systems with cropping patterns on dry land. This research uses survey, analysis, and needs analysis methods of decent living. Results The agroforestry system used to develop critical land is a human effort to control its reciprocal relationship with natural resources, with the hope that expanding the use of dry land by implementing a directed and planned agroforestry system for the people can improve the economy of the people around the primary forest which is based on forest products. The development of dry land management with an agroforestry system in community forest areas as a result of reforestation and forest development project activities from an institutional aspect is also able to foster farmer innovation in increasing the productivity of their land, one of which is the success of building community forests as a group on marginal land.

Evaluation of nutrient availability needs to be carried out to determine the ability of the soil to provide nutrients for plant growth, in this case the evaluation of the nutrient content of paddy fields in three locations in the Balige area, namely Huta Namora, Huta Bulu Mejan and Baruara. This is needed as information for the management of paddy fields on the provision of fertilizers in the future, both inorganic fertilizers and organic fertilizers. The purpose of this study was to evaluate the availability of soil nutrients such as organic C, total P, available P and soil pH after rice harvest. This research is a descriptive study by comparing data from the three research locations. In its implementation, 9 sample points of observation were chosen representing the location of each area. Every 3 sample points were mixed into one point of soil samples from the three research locations showing relatively the same results so that in one location there were 3 points of soil samples which were considered as replication 1, 2 and 3 replications. Thus, there were 9 soil samples for the three research locations. Based on the results of laboratory analysis shows that the nutrient content is relatively the same, namely for organic C content with low to moderate criteria, P-total nutrient content is on average between 6.55-7.52 (%) (low to moderate), for P is available between 27,241 – 28,909 with very low criteria. The pH parameter for paddy fields is relatively the same as the neutral criterion. This information becomes quite expensive information for the management of paddy fields in the future. The suggestion is to reduce the use of inorganic fertilizers and switch to the use of biological fertilizers and organic fertilizers.

Background: Energy-dense diets are of low nutrient quality but high energy content and this may have adverse health outcomes, especially in adolescence where the body is transforming from childhood to adulthood. Intake of energy-dense diets is associated with various forms of malnutrition including obesity, overweight, underweight and other micronutrient deficiencies. There is however scanty information about the relationship between the intake of energy-dense foods and adolescents' nutritional status. Aims: This study aimed to establish the relationship between intake of energy-dense diets and the nutritional status of adolescents in Nairobi County. Subjects and Methods: The study was a cross-sectional descriptive research design involving quantitative techniques of data collection. A total of 161 adolescents, 87 females and 74 male aged 10-14 years participated in the study. Cluster sampling was used to select schools in Embakasi South Sub- County. Simple random sampling was used to select adolescents in classes 5, 6 and 7. Data were collected using structured questionnaires, 7-day food frequency questionnaires, and anthropometric measurements. Data analysis was done using; SPSS version 23.0 (quantitative data), ENA for SMART (anthropometric data), Nutrisurvey software (Dietary data) and hypothesis testing (Pearson correlation). Results: The study established a burden of malnutrition among adolescents in Nairobi County (13%) underweight, (5.7%) overweight, (4.3%) severely underweight, and (2.5%) obese. The energy-dense foods which were found to have significant relationship with the nutritional status of the adolescents were: potato chips (r = 0.044, p = 0.045), doughnuts (r = -0.02, p = <0.001), pancakes (r = -0.001, p = 0.762), bhajia (r = -0.014, p = 0.897), cheese (r = -0.107, p-value = 0.660), and Regular soft drink (r = -0.147, p= 0.101.
