Meanwhile, nutrients availability in vertisol tends to be low because these elements are bound by clay particles, so the nutrient availability is limited for plantsThe aim of this research is to investigate the influence of rice husk biochar and corn cob biochar application on the changes in chemical properties of Vertisol soil and the vegetative growth of mung bean (Vigna radiata L.). The study was conducted using a Randomized Complete Block Design (RCBD) with an experimental approach. There were 8 treatments repeated 6 times, resulting in a total of 48 experimental units. The rice husk biochar (P) treatments included the control without rice husk biochar (BSP0), rice husk biochar at a rate of 60 g/kg soil (150 tons/ha) + 2.5 kg soil (BSP1), rice husk biochar at a rate of 30 g/kg soil (75 tons/ha) + 2.5 kg soil (BSP2), and rice husk biochar at a rate of 15 g/kg soil (37.5 tons/ha) + 2.5 kg soil (BSP3). The corn cob biochar (J) treatments included the control without corn cob biochar (BTJ0), corn cob biochar at a rate of 60 g/kg soil (150 tons/ha) + 2.5 kg soil (BTJ1), corn cob biochar at a rate of 30 g/kg soil (75 tons/ha) + 2.5 kg soil (BTJ2), and corn cob biochar at a rate of 15 g/kg soil (37.5 tons/ha) + 2.5 kg soil (BTJ3). The research data were analyzed using Analysis of Variance (ANOVA) at a significance level of 5%. Significant differences between treatments were further analyzed using the Duncan's New Multiple Range Test (BNJ) at a significance level of 5%. The soil analysis was carried out at the Soil Physics and Soil Chemistry Laboratories, Faculty of Agriculture, Universitas Mataram. The results of the research showed that biochar application influenced the chemical properties of the soil (pH, Cation Exchange Capacity, Organic-C) and the growth of mung bean plants in Lombok's Vertisol soil. Biochar did not have a significant effect on the height of mung bean plants at 7 and 14 days after planting (DAP), but it had a significant effect at 21, 28, and 35 DAP. However, the application of biochar did not significantly affect the number of leaves and dry weight of mung bean plants.","PeriodicalId":274989,"journal":{"name":"JURNAL SAINS TEKNOLOGI & LINGKUNGAN","volume":"19 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139149581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One crucial component of marine ecosystem that plays a major role in maintaining the balance of the marine environment is seagrass. The objective of this research is to provide critical insights into the dynamics of seagrass populations in Cempi Bay and offer an overview of the broader coastal ecosystem's condition. The research, conducted in June-July 2021 at 5 research stations, employed the transect method. At each data collection point, three transect lines were created perpendicular to the coastline. The distance between transect lines was 100 m, and each transect consisted of 10 quadrants measuring 1x1 m with a 5 m distance for each quadrant. Four seagrass species were identified: Thalassia hemprichii, Cymodocea rotundata, Halodule pinifolia, and Cymodocea serrulata. These species were found on sand substrates, with the highest total density and percentage cover observed at Station 5 (1135.22 ind/m2 and 40.74%). The results highlight the necessity for routine monitoring, mapping, and further research to comprehend seagrass population dynamics and support effective conservation policies. Implementation of recovery strategies, water quality management, and continued research support is imperative to ensure the sustainability of seagrass ecosystems and marine resources in Cempi Bay.","PeriodicalId":274989,"journal":{"name":"JURNAL SAINS TEKNOLOGI & LINGKUNGAN","volume":"20 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139152219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mangrove ecosystems contribute to the \"blue carbon\" plan which is capable of storing carbon well, this research was conducted to assess carbon storage within the mangrove forest ecosystem by combining Sentinel-2A satellite imagery with on-site field measurements. The data analysis findings indicate the presence of six distinct mangrove varieties, namely R. mucronata, A. marina, R. apiculata, S. alba, E. agallocha, and C. decandra. The R. mucronata type is the type that dominates the mangrove area with an average carbon amount of 122.1 tonnes/ha. Correlation analysis shows a strong relationship between IKVm and mangrove forest carbon stocks, with a correlation coefficient value of 80%. In the regression model, the power model provides the best equation for estimating carbon stocks with a coefficient of determination value of 64.4% giving a model equation of y = 109.51x1.2381.

Greenhouse gases include methane gas and carbon dioxide. In large quantities, this gas can cause damage to the atmosphere. Greenhouse gas emissions are dominated by waste management activities at landfills. Benowo Landfill is one of the Landfills that manages the waste of the residents of Surabaya City. The more waste that is piled up in the landfill, the more gas is produced. So it is necessary to estimate the occurrence of methane gas and carbon dioxide gas in landfills. LandGem is a model that is able to estimate greenhouse gases that will appear in landfills. In this research, greenhouse gas estimates were carried out at the Benowo landfill using 3 scenarios. This scenario is applied to determine the influence of weather (k value) on the landfill. The results showed that scenario 3 which uses a k value of 0.7 (wet area) has the highest estimate of methane and carbon dioxide compared to the other scenarios, namely 6.801 x 107 m3/year. This happens because the k value means that the landfill area has high rainfall and there is a bioreactor or leachate circulation system. This value is considered a good value for bacterial growth in landfills.","PeriodicalId":274989,"journal":{"name":"JURNAL SAINS TEKNOLOGI & LINGKUNGAN","volume":"38 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139149796","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This heightened vulnerability increases the likelihood of reaching a tipping point with the next shock or stressor. Identifying early warning indicators for tipping points is crucial for proactive coral reef management. Therefore, this study aims to comprehend the coral reef health parameters considered important and feasible for collection by local stakeholders, as well as identify factors facilitating the implementation of a community-based monitoring and early warning system in a fishers-dominated community. The approach used was Participatory Action Research. The results reveal twelve priority parameters deemed necessary by the local community and feasible for collection by local stakeholders, including the local community, university, and non-governmental organization. The identified parameters are: coral bleaching, visibility, temperature, pH, dissolved oxygen, salinity, current, coral percent cover, fish community, macroalgal canopy cover and composition, benthic composition, and plankton. Interpretive structural model and MICMAC analysis show nine enabling factors supporting the development of a community-led coral reef health monitoring and early warning system. These factors include team motivation, training and team capacity, connection with government, connection with university, facilitation by NGOs, supporting regulations, operational funds, access to equipment, and operation and maintenance of equipment. Team motivation stands out as the most influential factor, with strong driving power and dependence, making it crucial to manage as actions on it will have ripple effects on other factors.","PeriodicalId":274989,"journal":{"name":"JURNAL SAINS TEKNOLOGI & LINGKUNGAN","volume":"10 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139149698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
