Abstract

The topics of morphology, anatomy, and physiology are integral to biology learning, yet they often present challenges for students due to their abstract and complex nature. Difficulties in understanding body structures and invisible biological processes lead to low student interest and engagement. This study aims to identify innovative learning approaches through an analysis of national scientific literature over the past decade. The results show that the integration of digital technology and student-centered learning methods can improve conceptual understanding and learning motivation. The most prominent innovations include the use of VR and AR-based media to clarify visualizations, the use of interactive videos and simulations to explain biological functions, and the application of contextual learning models such as Problem-Based Learning (PBL) and Project-Based Learning (PjBL). These approaches have proven effective in creating a more immersive learning experience that is relevant to students' needs.

Abstract

This study aims to analyze the differences in various extraction techniques and their relationship to the yield and biological activity of phytochemical compounds from natural materials. The research was conducted through a systematic literature review from various reliable scientific sources over the last decade. The results indicate that extraction methods such as maceration, soxhlet extraction, microwave-assisted extraction (MAE), and ultrasound-assisted extraction (UAE) have varying effectiveness. The effectiveness of these methods is highly dependent on the type of material, solvent used, and process parameters such as temperature, time, and solvent-to-material ratio. Modern extraction methods such as sonication, MAE, and UAE tend to produce higher yields and better biological activity. These modern methods have the advantage of being more time-efficient and requiring fewer solvents, thus allowing the extraction of active compounds more optimally. Additionally, technologies like microwave and ultrasonic waves help break down the cell walls of natural materials, enhancing the release of phytochemical compounds more effectively and rapidly. However, conventional methods such as maceration and soxhlet extraction remain relevant, especially for materials containing thermolabile compounds that may degrade at high temperatures. These methods are still preferred to maintain the stability of active compounds sensitive to thermal degradation. Choosing the appropriate extraction method is crucial in producing high-quality extracts that can potentially be used as raw materials for phytopharmaceuticals, supplements, or other natural products. This study provides a strong theoretical foundation for further experimental research and guidance in selecting extraction methods based on the required efficiency and effectiveness for industrial applications. Thus, this study contributes to the development of more efficient and high-quality natural products.

Abstract

This study aims to analyze the quality of domestic wastewater based on three main parameters: pH, ammonia, and Chemical Oxygen Demand (COD). The wastewater samples were collected from an industrial area, chosen for its role as a primary source of domestic waste that can impact environmental quality. The pH was tested using potentiometry, while ammonia and COD concentrations were measured using UV-Vis spectrophotometry, a precise method for analyzing these substances. The results showed that the pH values of the wastewater ranged from 6.68 to 10.28. This variation in pH reflects the acidity or alkalinity of the wastewater, with some samples being neutral to slightly alkaline. The ammonia levels detected ranged from 0.0654 to 0.3849 mg/L. While these levels are within the limits set by regulations, they indicate a significant presence of ammonia in the wastewater, which requires continued monitoring. However, the most striking finding was the COD levels, which ranged from 21.60 to 245.71 mg/L, with some samples showing very high values. High COD levels indicate a large presence of organic matter, which can lead to a decline in water quality. Some samples with COD values exceeding the threshold of domestic wastewater quality standards, as stated in Ministerial Regulation No. 68 of 2016, require additional treatment to reduce organic contamination. Overall, while the pH and ammonia values remain within safe limits, the high COD levels in some samples indicate that further treatment is necessary to reduce organic pollution. This study emphasizes the importance of routine monitoring of domestic wastewater to protect environmental quality and prevent broader negative impacts on aquatic ecosystems and human health.

Abstract

Feed is a key component in catfish (Pangasius hypophthalmus) cultivation because it directly affects the growth rate, health, and productivity of the fish. Among the various nutrients contained in feed, protein plays a crucial role, particularly in the formation and repair of fish body tissues. Adequate protein content supports optimal growth, while protein deficiency can reduce productivity. Therefore, analyzing protein levels in feed is essential to ensure its quality. This study aimed to analyze protein levels in catfish feed using the Kjeldahl method. The analysis was conducted at the Pekanbaru Center for Standardization and Industrial Services (BSPJI). The Kjeldahl method was chosen because it is known to have a high level of accuracy and reliability. The procedure involves three main stages: destruction, distillation, and titration. The working principle of this method is to convert organic nitrogen in the sample into ammonia, which is then captured and measured to determine nitrogen levels, which are then converted to protein levels. In this study, five feed samples with codes U-139 to U-142 were used. The test results showed that the protein content of the samples ranged from 20.44% to 23.09%. Furthermore, a Relative Percent Difference (RPD) value of 0.0013% was obtained, indicating a very high level of measurement precision. The analysis results were then compared with the fish feed quality standards based on SNI 2534:2006, and it was found that all samples met the minimum protein content requirements. Thus, this study confirms the effective and accurate use of the Kjeldahl method in analyzing protein content in catfish feed. These results also provide important information for farmers and feed producers in ensuring the quality of feed used to support catfish farming productivity.

Abstract

Bekasam is a traditional Indonesian fermented product made from tilapia (Oreochromis niloticus) through a spontaneous fermentation process with the addition of rice and salt. This fermentation process encourages the growth of various microorganisms, especially bacteria, which play a role in the formation of flavor, aroma, and natural preservation of the product. This study aims to observe the microbiological characteristics of bekasam tilapia through colony observation on agar media and microscopic staining using crystal violet and safranin. Macroscopic observations showed the presence of microbial colonies that were round, cloudy white, with a smooth surface and even edges. These colony characteristics indicate good microbial growth on agar media. Microscopically, the bacteria observed in bekasam samples had an irregular distribution, forming aggregates that absorbed intense purple and pink colors. Crystal violet staining gave a purple color to gram-positive bacteria, while safranin gave a pink color to gram-negative bacteria. These findings indicate that bekasam contains an active microbial community that plays a role in the fermentation process. This microbial community can be observed visually through simple staining that provides an overview of the types of bacteria involved in the fermentation process. Microbiological analysis such as this is crucial for understanding the fermentation dynamics of traditional food products like bekasam. Thus, this study provides deeper insight into the microorganisms involved in bekasam production, as well as the importance of monitoring microbiological quality in the manufacturing process of traditional fermented products. Furthermore, the diversity of microbes involved in bekasam fermentation can affect product quality and consistency. Therefore, monitoring the dominant bacterial species during the fermentation process is crucial for maintaining bekasam quality, including its taste, texture, and safety for consumers.

Abstract

The pitcher plant (Nepenthes sp.) is a type of predatory plant typically found in tropical regions and has a pitcher structure designed to attack insects. The pitcher's structure acts as a small ecosystem that supports a variety of microorganisms, both those living on the surface (epiphytes) and those within the tissue (endophytes). This study aimed to extract and identify microorganisms present on the surface and interior of the pitcher plant. Samples were taken from peat swamps and separated using Nutrient Agar (NA) for bacteria and Potato Dextrose Agar (PDA) for fungi. The discovery process involved examining morphological characteristics both visually and under a microscope. The results revealed differences in the types of microorganisms between the outside and inside of the pitcher, influenced by the microenvironmental conditions in each area. These findings can serve as a foundation for further study of the bioactive potential of microorganisms from the pitcher plant.

Abstract

Solid waste from the tapioca processing industry, which is based on cassava (Manihot esculenta), is a medium rich in organic matter, particularly starch, that supports the growth of various types of microorganisms, especially fungi and bacteria. This study aims to isolate and observe the morphology of microorganisms from solid waste of cassava from the tapioca industry using Potato Dextrose Agar (PDA) medium in a series of pharmaceutical microbiology practicum. Waste samples were taken from the tapioca processing site, then underwent a serial dilution process and inoculation into PDA medium, which was incubated at 28–30°C for 5 days. The isolation results showed the growth of microorganisms with diverse colony morphologies, which are suspected to originate from the genera Aspergillus, Penicillium, and Rhizopus, based on macroscopic and microscopic characteristics. The presence of these microorganisms indicates the potential utilization of cassava waste as a source of microbial isolates for biotechnological and pharmaceutical applications, such as enzyme production and development of bioactive compounds. This practicum activity also contributes to increasing students' understanding of isolation techniques, microorganism characterization, and their role in biological-based waste management.

Abstract

This study aims to analyze the differences between various extraction techniques and their relationship to the yield and biological activity of phytochemical compounds derived from natural materials. A systematic literature review was conducted by analyzing relevant and reliable scientific publications published within the last five years. The findings indicate that extraction methods such as maceration, soxhletation, microwave-assisted extraction (MAE), and ultrasound-assisted extraction (UAE) demonstrate varying levels of effectiveness depending on the type of material, solvent polarity, extraction temperature, and duration of the process. Modern extraction methods, particularly sonication, MAE, and UAE, have been shown to produce higher yields with enhanced biological activity while offering greater efficiency in terms of reduced time and solvent consumption. On the other hand, conventional techniques such as maceration and soxhletation remain relevant, particularly for thermolabile compounds that are sensitive to high temperatures. The selection of an appropriate extraction method plays a crucial role in obtaining high-quality extracts that can serve as potential raw materials for phytopharmaceuticals, functional foods, dietary supplements, and other natural products. This review not only highlights the advantages and limitations of each technique but also emphasizes the importance of aligning method selection with specific research objectives and compound characteristics. Overall, this study provides a theoretical foundation for future experimental research and serves as an initial guideline for determining extraction strategies based on efficiency, effectiveness, and sustainability.

Abstract

This research focuses on the synthesis and characterization of the double salt copper(II) ammonium sulfate hexahydrate, Cu(NH4)2(SO4)2·6H2O. The study aims to obtain the compound in crystalline form and evaluate its properties through yield calculation, solubility testing, and Fourier Transform Infrared (FTIR) spectroscopy. The synthesis involved reacting copper(II) sulfate pentahydrate (CuSO4·5H2O) with ammonium sulfate ((NH4)2SO4) under controlled conditions, followed by crystallization. The process produced 10.84 grams of crystalline Cu(NH4)2(SO4)2·6H2O with an 86.23% yield, indicating efficient synthesis. Solubility tests showed that the crystals were polar, soluble in polar solvents like water and hydrochloric acid (HCl), partially soluble in ammonium hydroxide (NH4OH), and insoluble in less polar solvents like ethanol and chloroform (CHCl3). FTIR analysis confirmed the presence of functional groups such as O–H, N–H, and S–O stretching vibrations, supporting the proposed molecular structure. The findings demonstrate that Cu(NH4)2(SO4)2·6H2O can be efficiently synthesized, and its physicochemical properties align with theoretical expectations. This study contributes to the understanding of double salt synthesis and characterization, relevant for inorganic chemistry, material science, and potential applications in catalysis and coordination chemistry.
