Abstract

The neem tree has strengths such as effective and environmentally friendly active compounds, as well as the ability to improve the quality and productivity of plants organically. However, the use of botanical pesticides has several challenges, such as potentially lower effectiveness compared to chemical insecticides, high production costs, and requiring specific knowledge in formulation and application. Botanical pesticides are readily available tools for insect pest management and are eco-friendly. The research results show that a neem formula at a concentration of 20 ml.l-1 water can cause mortality of brown planthopper is 48.75 - 70%, while mortality in the synthetic insecticide (positive control) at a concentration of 2 ml.l-1 water (as recommended) resulted in 45% mortality. It is obvious that there is a need to develop biological control as alternatives for eco-friendly and sustainable for pests’ control in insect’s pest management strategies.  This research study has both qualitative and quantitative approach, data collection strategies were desk review of information and will be based on empirical data and literature. For the desk study, relevant internet web pages were browsed to have an overview of the key concepts of the research issue, problem of pests and diseases control and benefit of neem tree as botanical pesticides. Nevertheless, the use of botanical pesticides can provide long-term benefits to the environment and human health and support more sustainable agriculture. There is a great opportunity for the development of more effective and affordable technology for botanical pesticide production for farmers, but there are also threats such as strong competition from synthetic pesticides. The objective this study aims to determine the potential of neem (Azadirachta indica A.Juss) as a plant producing botanical pesticides as an effective and sustainable biological control alternative.

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

Rosmarinus officinalis is a medicinal plant, which belongs to family Lamiaceae. It is an evergreen bush. It was analyzed for its phytochemical constitution and antibacterial activity. For this purpose, leaves of n-hexane, ethyl acetate and methanolic extracts were used. The tests of phytochemical screening showed that the plant leaves contain anthraquinones, terpenoids, flavonoids, reducing sugars, saponins, cardiac glycosides, coumarins, phenols, carbohydrates, proteins, steroids, alkaloids and quinones, while tannin was absent. The antibacterial activity was determined against E. coli and staphylococcus aureus; the invitro antibacterial activity was performed by disc diffusion method. The n-hexane and ethyl acetate extracts showed no antibacterial activity against E. coli while ethyl acetate extracts showed antibacterial activity against Staphylococcus sp. The results showed that the highest mean inhibition zone was observed in the methanolic extracts.

Abstract

To ensure a safe drinking water supply, it is necessary to protect water quality. The proposed project aims to understand water quality data analyzed from a temporal and spatial perspective on the following physiochemical parameters: DO, pH, temperature, Secchi disc turbidity, conductivity, nitrate, chlorophyll α & phosphate. The results provide information to evaluate the status of the water quality and its suitability for human consumption. These variables related to the general characteristics of water quality and trophic level were used for calculation of a water quality index (WQI) and trophic state index (TSI) to assess 3 lakes in Puerto Rico: Lake Cidra, Lake Carraizo and Lake Guineo. Presence or absence of macrophytes were monitored during six months in the three reservoirs in Puerto Rico as well as the parameters mentioned above. The objective of this investigation is to discuss the trophic state and water quality in 3 different trophic state reservoirs in Puerto Rico. Results were correlated with the density of the macrophyte species, Eichhornia crassipes. Variations of water in situ multiparametric sampling were recorded for 6 months. Thus, integrating components that define the status of reservoirs using multiparameter measurements from various perspectives; a better diagnosis is expected regarding the water quality assessment. This investigation aims to undertake a comprehensive study of water quality by implementing the WQI and TSI indices, considering physical, chemical, and biological parameters with respect to eutrophication and ecological considerations for three reservoirs in the Puerto Rico, providing information regarding the quality of water and trophic state of the chosen reservoirs. Overall WQI results revealed that the water quality improved after the Hurricane Fiona’s occurrence. Trophic State Index after the hurricane showed slight fluctuations in the reservoirs.

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.

Abstract

The Design Study of the Semarang Sea Wall Development Plan will result in a change in environmental conditions in the eastern coastal area. Changes in environmental conditions that will occur in the area include changes in sea currents which originally flowed eastward moving to the Tambak Lorok area on the west coast and the Java Sea. The method uses Descriptive Qualitative with the help of SEM analysis. Based on the results of the analysis of the SEM model, it is known that the indicator that will be affected based on the Design Study of the Sea Wall Development Plan is the Mangrove Ecosystem of 0.477. To maintain the sustainability of the mangrove ecosystem, a coastal area management system needs to pay attention to the principle of the continuity of the function of existing mangrove forests. Mangrove ecosystems in coastal areas that are maintained, and supported by awareness and common perceptions of various parties about the importance of the existence of mangrove ecosystems will have an impact on the sustainability of coastal areas.

Abstract

Tribulus terrestris L. (T. terrestris) is widely distributed worldwide (Australia, Europe, India, North Africa). It typically contains a substantial amount of active ingredients, especially saponins, alkaloids, flavonoids, tannins, terpenoids, and phenol carboxylic acids. Additionally, T. terrestris has been frequently used in folk medicine and as a food supplement, highlighting the importance of evaluating its phytopharmacological properties. Various hypotheses suggest that this species may have significant potential in preventing and improving various human conditions, including diabetes, inflammatory diseases, low sexual desire, and infertility. Phytochemical studies reveal a significant disparity in the content of active substances, with a notable gap in the concentrations of spirostanol saponins and furostanol, which are the predominant active ingredients associated with therapeutic effects. The objective of this present review is to evaluate T. terrestris -based formulations by exploring various potential mechanisms of action, aiming to determine whether the use of T. terrestris supplements is justified in the context of diabetes and its complications.

Abstract

A leading cause of land use and land cover changes is human population growth as well as urbanization. This study aimed at identifying the changes in land use and land cover around a bridged point of Ikpoba River, Benin City, Nigeria, coupled with  the examination of selected physicochemical attributes of surface water samples collected from the river around the bridged section. Land use and land cover change analysis was done using images from Landsat 5 and 7 for the years 1991, 2002, 2012 and 2022 using ENVI 5.3 software. Surface water samples were collected from 3  sampling points  in a three month period; May to July, 2023. The monthly grouped mean data for each sampling point were subjected to one way analysis of variance (ANOVA) and  mean separation was also carried out using  a post hoc test; Duncan’s multiple range test at 95% level of confidence.Land use maps revealed that there was a decrease in the forested areas, grasslands and water bodies and an consequent increase in the barren land as well as  built up areas between the years; 1991 and 2022. There were variations in the mean pH and turbidity values. The range of these parameters were; 5.91± 0.05  to 6.76 ±0.10 and 12.50 ±0.50 to 131.50 ± 3.50 mg/l. The variation in the  mean pH values was insignificant (p>0.05) whilst the difference in the mean turbidity readings was significant (p<0.05). It is recommended that protective measures be implemented to protect the remaining forested areas while encouraging reforestation of barren lands.
