Abstract

In Indonesia, the pulp of snake fruit is consumed while the peel remains unused. In this context, the phytochemical content of snake fruit aqueous extract was used as a reducing and capping agent in the preparation of silver nanoparticles (AgNPs). According to the phytochemical screening, snake fruit peel containing alkaloids, flavonoids, tannins, saponins, and polyphenols was used to synthesize AgNPs. Therefore, this research aimed to optimize the synthesis of AgNPs using snake fruit peel extract (Salacca zalacca) in terms of synthesis time, temperature and phytochemical screening. AgNPs were successfully synthesized using a volume ratio of 2:15 (20 mL of 1.00 mM AgNO3 to 150 mL of snake fruit peel extract) in a sealed container in a dark room. Furthermore, characterization was carried out using a UV-Vis spectrum and Fourier Transform Infrared Spectroscopy (FTIR). The UV-Vis spectrum characterization in a solution incubated for 30 minutes at 30 °C with a concentration of 1.00 mM AgNO3 was differentiated at a wavelength of 410 nm with an absorbance of 2.361. According to the FTIR characterization, there was an increase in the intensity of the O – H functional groups in the AgNPs solution compared to snake fruit peel extract. The results showed that the synthesis of AgNPs from snake fruit peel extract was optimal at a concentration of 1.00 mM AgNO3 at 30 °C and 30 minutes of incubation.

Abstract

In ‘Neraca Pengelolaan Sampah Kota Madiun‘ data for 2023, waste production was 44,750.39 tons/year, while the amount of waste reused and recycled was 4,600.28 tons/year and processed waste that went to landfill was 31,444.75 tons/year. Waste banks began to be formed in Madiun City from 2010 to 2023. There are 168 waste banks that have been formed and only 49.4% are still actively operating. The phenomenon found in the field is that involvement between stakeholders in the Waste Bank program in Madiun City is still not optimal, and this finding is the basis for this research, namely analyzing the relationship model of stakeholder roles in managing the Waste Bank in Madiun City. Madiun City. This research uses a mixed method paradigm to obtain a holistic picture of the characteristics and relationships of stakeholders in the Waste Bank program in Madiun City. All data in this study were analyzed using MACTOR software. The results of this research conclude that the stakeholders who have the greatest influence are DLH and public figure (Lurah) who are the main actors in waste bank management, because they are involved in planning, implementation and policy so that there is still a need to improve their relationships and roles in supporting the success of the waste bank program. Madiun City. Very strong convergence between actors shows that between the Matahari Sampah Bank and community leaders, Sedoro Asri Waste Bank, Sehati Waste Bank, Pesanggrahan Waste Bank and Risky Lancar Manis VI Waste Bank. Very weak convergence is shown between the Madiun City Environmental Service and NGOs, Pertamina, Academics, the PKK Mobilization Team and the Griya Kencana Waste Bank.

Abstract

This research investigates the competence of junior high school science teachers in Palu City, Indonesia, regarding laboratory teaching. The study aims to assess teachers' abilities in planning, implementing, and evaluating laboratory-based learning. Data were collected through observations, document reviews, and interviews with science teachers across six public junior high schools. The findings reveal that all schools engage in laboratory learning to some extent, with varying degrees of success. Teachers often create their own worksheets or use existing guides from science kits. Challenges identified include insufficient laboratory space, incomplete equipment, and a lack of dedicated laboratory assistants. Despite these obstacles, science teachers collaborate to ensure effective laboratory learning, highlighting the need for improved resources and support to enhance the overall quality of science education. The study concludes that while teachers demonstrate competency in laboratory teaching, further development is needed in creating practicum guides, conducting experiments, and assessing student skills. Future research should explore the impact of teacher competence on student learning outcomes in laboratory settings.

Abstract

It is important to carry out research on heavy metal in fish body. The specific aims and targets of this research are: Want to know the metal content of Cadmium (Cd) in Ricefield eels (Monopterus albus) which comes from Rawa Taliwang Lake. The specific benefit is to protect consumers who consume fish from heavy metal contamination. The research was carried out at Rawa Taliwang Lake, namely in an area that is submerged in water. There are 2 research stations, namely in the eastern and western parts of the lake. Data collection method was carried out using traps (Bubu). Four Ricefield eel samples were taken at each station. Next, the rice eel samples were put into a plastic bag and then stored in a sample box. The research samples were then analyzed at the Mataram Uviversity analytical laboratory and at Environmental Laboratory of the Environmental and forestry services West Nusa Tenggara Province.  The data analysis method is carried out by taking the tissues from the Ricefield eel muscles, and then analyzed for Cd heavy metal content by using Atomic Absorption Spectrophotometer. Measurement of heavy metals in Ricefield eel tissue was carried out by adding concentrated HNO3 and HClO4 , heated at a temperature of 60-70ºC for 2-3 hours until the solution was clear. Samples are ready to be measured with AAS using an air-acetylene flame. The conclusion of this research is that the content of Cd heavy metal in Ricefield Eels (Monopterus albus) originating from Rawa Taliwang Lake ranges from 2.55 - 4.01 mg/kg (ppm).

Abstract

Sediments are temporary and long-term reservoirs for waste including microplastic particles.  Microplastics are large-sized plastics that are under 5mm in size. microplastic particles with a density greater than water can enter the sediment and accumulate. High water utilization activities can be a way for plastic waste from land to enter the waters, one of the rivers that has high utilization is the Siak River in Pekanbaru city. This study aims to analyze the abundance and distribution of microplastics based on 3 (three) stations in the Siak River. The research procedure consists of sampling, microplastic separation, and microplastic analysis. The results showed that the Siak River in Pekanbaru city contained microplastic types of fragments (32%), films (31%), fibers (25%), and granules (12%). The highest abundance of microplastics was at station 1 with an average abundance of 32.67/kg which was dominated by fragment-type microplastics. The Siak River in Pekanbaru city has been contaminated with microplastics which can be intentionally or unintentionally eaten by aquatic biota.

Abstract

Tartrazine is a yellow synthetic dye that is widely used as a coloring agent in food and beverage products. However, the safety of this chemical compound is still a concern due to potential health risks such as allergic reactions, hyperactive behavior in children, increased risk of cancer and other negative impacts. This research aim to introduces a new approach to reduce the concentration of tartrazine dye using cobalt and nickel doped TiO2 nanowires. Cobalt- and nickel-doped TiO2 nanowires were synthesized by a hydrothermal method, followed by thermal treatment at 270°C, and then used in a photocatalytic reactor using UV irradiation to facilitate the reduction of tartrazine concentration. Material characterization was carried out to determine the morphology and crystallinity of the photocatalyst which is effective in reducing the absorption of tartrazine solution. The photocatalytic degradation experiment demonstrates the ability of the synthesized material as a photocatalyst, effectively reducing the absorbance of tartrazine solution, a commonly used food coloring. This finding promises significant progress in the development of sustainable food safety strategies by offering a dye degradation method.
