Effectiveness of Mendong (Fimbristylis globulosa) as A Phytoremediation Agent for Total Ammonia and Total Nitrogen Leachate
Landfills are one of the causes of environmental pollution resulting from the disposal of human activity waste without further treatment (Yusri et al., 2020). In 2023, the total waste generation reached 1,270.00 tons per day, with 900 tons of waste being transported to the landfill each day (Harjanti, 2020). This waste accumulation produces leachate—a thick, dark-colored liquid that carries pollutants and materials from the waste—which has the potential to contaminate the surrounding environment, including the Kreo River. Therefore, phytoremediation using Mendong plants is proposed to reduce the pollutants in the leachate. This research employed an experimental method with a Completely Randomized Design (CRD), using Mendong plants (Fimbristylis globulosa) and three biomass variations: P0 (0 g), P1 (1000 g), and P2 (2000 g). Each treatment involved 10 liters of leachate and was replicated three times. The phytoremediation process proved effective in reducing total ammonia levels in the leachate, with a reduction of up to 63%, and the highest total nitrogen reduction reached 53%. This phytoremediation approach can assist in reducing excess total ammonia in water bodies by absorbing organic pollutants through plant roots, as Mendong exhibits hyperaccumulator and hypertolerant properties. It is concluded that Mendong plants are effective in lowering total ammonia and total nitrogen levels in landfill leachate.

Biodegradation of Polystyrene Waste using Mealworm (Tenebrio molitor) Larvae as a Sustainable Waste Management Approach
Styrofoam is widely used as packaging for food, drinks and electronic goods. Usually stirofoam is only used once and thrown away. Styrofoam causes environmental problems, so efforts are needed to degrade it. Using larvae Tenebrio molitor is expected to be an innovative and environmentally friendly solution. The larval stage is used because larvae require large amounts of food for their growth. The larvae's food consists of organic waste such as fruit, vegetables, leaves, rice and others. In fact, stirofoam is considered organic waste because it is made from petroleum which contains hydrocarbons. T. molitor were chosen because they are not consumed by humans. This research aims to analyze the ability of T. molitor to be biodegradation agents for stirofoam. The research stages include cultivating T. molitor for 30 days and analysis which includes viability analysis and larval content using FTIR. The research method used is an experimental method with quantitative data collection. The results of the study showed that even though there was chewing activity, there was no stirofoam content in the bodies of T. molitor.

Effectiveness of Water Bamboo as Phytoremediation Agent BOD and COD Leachate
Leachate is a liquid with an unpleasant odor and dark color that generally contains high organic and inorganic matter. High levels of organic and inorganic matter in leachate will potentially cause environmental pollution if not treated properly. One of the efforts that can be made to overcome these problems is with phytoremediation techniques. This study aims to determine the effectiveness of water bamboo (Equisetum hymale) as a phytoremediation agent of Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) leachate of Jatibarang landfill. This study used experimental research with a one-factorial Complete Randomized Design (RAL) design with three treatments (P0 without water bamboo, P1 750 gr water bamboo, and P2 1000 gr water bamboo). Based on the results of research shows that water bamboo plants can reduce BOD and COD levels. The decrease in leachate BOD levels was caused by the phytoremediation process by water bamboo during the study, where the organic matter content in leachate would be degraded by microorganisms. Meanwhile, COD levels decreased due to the chemical oxidation reaction process and phytoremediation process that runs side by side. The effectiveness of reducing BOD levels most optimally occurred in treatment P2 on day 7 of treatment, which was 28.42%; while the percentage of effectiveness of reducing COD levels most optimally occurred in treatment P2 on day 7 of treatment, which was 39.14%

Production of Biochar Briquettes from Coconut Leaves
Coconut leaf waste (Cocus nucifera), which contains various beneficial compounds, has not been utilized optimally by the community. Coconut leaves contain a valuable biomass of around 44,000 tonnes/ha to 67,000 tonnes/ha. This has the potential to be used as biochar. The research method used in this research is descriptive experimental research using coconut leaves as raw material for biochar briquettes using a pyrolysis carbonization process. This study used differences in the composition of starch which acts as an adhesive with 3 different variations, namely 2%, 4% and 6%. Based on the results of the ash content test and the calculation of the water content and density, the biochar briquettes in all samples complied with SNI 01/6235/2000.
Is the Climate Change being Real? A Case Study of College Students’ Climate Change Perception at Universiti Malaya
Climate change is a socio-scientific issue which affecting to human life. Climate change was induced by the human activities (anthropogenic). People perception toward climate change might important to taking action address to climate change. This paper aim to analyze horticulture class students’ perception toward the climate change. Using a survey method, this study conducted in Biology Institute, Universiti Malaya, Malaysia. Fourthly students who enroll horticulture class declare be willing to participate in the study. The questionnaire consists of 25 questions reality (Q1-Q5), causes (Q6-Q10), valence of consequences 9 (Q11-Q14), spatial distribution (Q15-Q19), and temporal distribution (Q20-Q25). Data collection using a questionnaire in the form of a google form that was done for 30 minutes. The study find that students believe climate change is a serious problem in Malaysia region. Students also believe that climate change caused by human activists rather than natural phenomena. Climate change have already felt now and impacting local region and worldwide. This climate crisis giving a massive change in human lifestyle. In suggestion, all people around the world should take actions to tackling the climate change, both mitigation or adaptation ways. Mitigation and adaptation strategies needed to limiting the impact of climate change.
Geospatial Assessment of Aridity and Erosivity Indices in Northwest Somalia Using The CORINE Model
The degree of soil erosion depends on the erodibility of the soil and the erosive agents. The primary energy source for soil detachment and transport in water erosion processes is rain and runoff. In the northwest region of Somalia, we thoroughly evaluated the aridity and erosivity indices. This study, aridity and erosivity indices and arid periods of Woqoyi Galbeed were assessed. In the CORINE methodology, four parameters are used to evaluate the potential and actual soil erosion risks: Soil erodibility, erosivity, topography (slope), and land cover. Fournier Precipitation Index and Bagnouls-Gaussen Drought Index were calculated using rainfall data that were measured from 2011–2019 in the region and temperature data that were taken from 50 meteorological stations. The study illustrates that most of the study area is under moderate erosion risk. Although a small portion of the Southern parts of the study areas have high erosion risk, these areas have low erosion risk due to the very steep slope. The Erosivity Index quantifies the effect of rainfall impact and also reflects the amount and rate of runoff likely to be associated with precipitation events. Evaluating the result of MFI and BGI overlaid shows that there is low erosivity risk in the northern part of the country. It includes the Bossaso, Aburin, Dararweyne, Burco, Xudun and Iskushuban weather stations. It is covering the area of 204978, 65km2, which represents 32.14% of the study area. This indicates that Northern part of the country, annual rainfall is low, whereas some areas like Erigabo and gebiley are relatively moderate in the MFI.
Development of the Maze Chase Game in Guided Discovery Learning on Student Learning Outcomes
Student learning outcomes have an important role in shaping students into careful and skilled individuals. As times progress, technological advances must be balanced with students' cognitive learning outcomes to create an advanced young generation. Improving the learning model towards deficiencies in the learning model such as deficiencies in the guided discovery learning model by considering technological advances aims to maximize student learning outcomes. The aim of the research was to determine the validity of the maze chase game media developed and the differences in the use of maze chase game media development in guided discovery learning between the experimental class and the control class. The development method in this development research is divided into three stages, namely define, design, and develop, while the differentiation test uses a quasi-experimental research design using the pretest-posttest control group design method. The research location is at SMP Negeri 23 Semarang with a sample of class VII A as the experimental class and class VII B as the control class at SMP Negeri 23 Semarang for the 2022/2023 academic year. The data collection technique uses purposive sampling technique and data collection uses test and non-test instruments in the form of questionnaires. The non-test instrument is used to determine the quality of the maze chase game media which shows valid quality, very good readability and very practical practicality. In the test data, there was an increase in N-Gain in the experimental class which was higher than the control class by 0.13 in the medium category. The results of the differentiation test using the Independent Sample T Test showed that there was a significant difference between the experimental class and the control class with a tcount>ttable value of 1.98.
