Abstract

Balanites aegyptiaca known as the desert date is an underutilized and neglected wild fruit tree/shrub of the arid and semi-arid zones with high economic potential. This study, therefore, was conducted to investigate the yield, physico-chemical and phytochemical properties, proximate and mineral composition of desert date kernel oil from different locations. Oil was extracted using the soxhlet apparatus, while hexane served as solvent. Standard procedures were used to determine the yield and properties of desert date kernel oil. The data obtained were subjected to the analysis of variance (p< 0.05). Oil yield (%) was found to range from 21.09±1.04-43.95±1.85 and varied significantly among the locations. Acid and saponification values (mg KOH/g) increased significantly from 2.11±0.07 to 1.36±0.07 and 76.35±0.22 to 179.85±0.90, respectively. The refractive index ranged from 1.36±0.15 to 1.48±0.06, while the iodine value (mg KOH/g) varied significantly from 67.07±1.53 to 85.33±2.52. Saponins, tannins, and phenol were discovered to vary significantly among the locations, and range from 3.82±0.30 -5.83±0.45 (mg/100 g), 1.31±0.10 - 1.68±0.03 (mg/100 g) and 1.51±0.05 - 2.09±0.06 (mg/100 g), respectively. The broad variability observed in the properties of desert date kernel oil among locations indicates the feasibility of improving kernel oil yield and properties through selection

Abstract

Waste is an environmental problem that is still not fully resolved properly even though the resulting impact has a major effect on environmental pollution, especially solid medical waste. The purpose of this study was to assess the characteristics of solid medical waste at Undata Hospital based on its sources and types, calculate the average weight of solid medical waste generated per day, and evaluate the solid medical waste management system with sorting, packaging, collection and transportation modes in accordance with the criteria of Permen of Environment and Forestry Number 56 of 2015 and Permenkes Number 2 of 2023. This research uses a qualitative approach with a descriptive research type. This research was conducted in August-September 2023. The sampling technique in this study used Purposive Sampling, with 18 informants selected from each unit/room/installation at Undata Hospital, Palu City. Based on the results of the study, it was found that every day Undata Palu Hospital produces domestic waste as much as ± 270 kg / day. The results of the evaluation of the solid medical waste management system at Undata Palu Hospital show that basically it is quite effective but not optimal, because the storage process shows non-compliance with the guidelines for medical waste management by the Ministry of Health Number 2 of 2023, namely storage in TPS which should not be more than 2x24 hours, but in fact the accumulation of solid medical waste is stored for 1 month in the LB3 TPS due to delays in transportation by third parties. This causes a large amount of solid waste in the TPS so that the TPS becomes full and dangerous because the waste undergoes a process of decomposition and decay, which is harmful to the environment and human health. Undata Hospital needs to maximize the procurement of internal medical waste processing equipment (incineration equipment) which needs to be supported by the Environmental Agency and the relevant Health Office to prevent environmental pollution from medical activities.

Abstract

The use of clean water around the world continues to increase along with the increase in population and is increasing when the whole world is hit by the COVID-19 pandemic. Therefore, research is carried out to treat greywater waste effectively in a simple and inexpensive way. The method used in this study is a single method, namely filtration (a mixture of soil and sand, activated char- coal and gravel), Lepironia articulata and a combination of the two methods, namely constructed wetland subsurface vertical flow. The results of this study showed a decrease in BOD and COD levels reaching 97%, 88% phosphate, 18% pH and 95% MBAS in the constructed wetland. This is due to the synergistic interaction between plants, media and microorganisms in removing pollutants effectively. This research needs to be developed further and explore the capabilities of each constructed wetland element, especially the Lepironia articulata.

Abstract

Coconut fiber, considered an organic waste, emerges as a promising alternative carbon source for graphene oxide production—a material characterized by its conductive nature due to oxidation and the introduction of functional groups. The synthesis process involves carbonization with varied holding times (10, 20, and 30 minutes) and the utilization of Triple Superphosphate (TSP) and Ferrocene catalysts at concentrations of 10 wt.% and 20 wt.%. Subsequently, the sonication method is employed to enhance the electrical conductivity of graphene oxide post-carbonization. Notably, the electrical conductivity tests, conducted using a sourcemeter, revealed the optimum performance at 20 minutes of carbonization duration and a 20 wt.% TSP catalyst concentration, yielding an impressive electrical conductivity of 11,489.86 S/m. These findings underscore the significance of tailored parameters in optimizing graphene oxide synthesis for applications such as high-conductivity battery anodes.

Abstract

Alzheimer's disease (AD) stands as the primary cause of dementia, marked by its neurodegenerative essence, which results in cognitive impairment associated with memory and a decline in functionality. Currently there is no drug which can permanently cure the nervous lesions as well as completely eradicate this pathogenesis. The aim of this research is to examine the acetylcholinesterase activity of flavonoids identified in Tribulus terrestris L. (Tt) by predicting ligand-receptor binding. The research process begins with the preparation of protein and ligand structures. Subsequently, docking is performed, interaction between protein-ligands is then analyzed and visualized. Four phytoconstituents of Tt were chosen, and molecular docking simulations revealed that all four compounds exhibited good binding affinities. Based on the predicted ADMET values using the Lipinski rule, compounds with potentially good activity were identified. The results suggest that these compounds may exhibit anti-acetylcholinesterase activity.

Abstract

Understanding disputing styles is very important for solving a problem. The purpose of this research is to examine descriptively the problems in the Kasinan protected forest and to identify the conflicting styles of each party so that an appropriate resolution of the problems can be developed. This research was conducted in the protected forest of Kasinan, precisely in Pesanggrahan Village, Batu City. Data collection was carried out qualitatively, namely through interviews, observation, and documentation. The analysis used adapts the Disputing Style Analysis (AGATA). The results of the research show that the problems in the Kasinan protected forest stem from the use of the forest for tourism by relying on water sources from the Kasinan protected forest. The impact was a decrease in the discharge of water flowing into the rice fields and residents' homes, resulting in protests from residents. Actors involved in the problem include residents of Pesanggrahan village, HIPPA-HIPPAM, Pesanggrahan Village Government, Sadar Alas community, Perhutani KPH Malang, BKPH Pujon, and Walhi. Each party has various problems, including environmental beauty, reducing water discharge, and tourism interests. Communities are the most disadvantaged because they feel the impact directly. Each side has a different style of conflict. However, especially for residents of the Sadar Alas community, they have a competitive dispute style. So, in an accommodation style, the village government formed a team of Kasinan Forest Utilization Problem Resolution Facilities and held meetings including villagers, HIPPA-HIPPAM, Alas Awareness Community, Perhutani, and the Mayor of Batu City to negotiate and facilitate the proposal for zoning based on local policies so that the environment is beautiful. and the tour continues. So support from parties who have full authority, such as the Mayor of Batu City, is needed in order to realize a resolution to the conflict.
