Abstract

The Way Besai Hydroelectric Power Plant (PLTA) is located in West Lampung Regency, Lampung Province, with a capacity of 90.4 MW and utilizes water from the Way Besai River. The availability of stable water discharge is highly dependent on the vegetation conditions in the catchment area. This study aims to examine the diversity of flora and vegetation sustainability in the Way Besai hydropower plant area using an exploration method divided into six observation lines. The results showed that there were 57 types of plants belonging to 21 families. The most common species are sonokeling (Dalbergia latifolia) with 140 individuals and seripit (Crypteronia paniculata) with 113 individuals. The families with the highest number of species are obtained from the families Moraceae and Fabaceae. The types of the Moraceae family are dominated by Ficus spp., which acts as a source of animal feed, while from the Fabaceae family, there are more types of multipurpose plants (MPTS). The diversity of species and evenness of flora around the Way Besai hydropower plant is relatively high, as shown by the diversity index value (H') of 3.281 and the evenness index value (E) of 0.812. Although this value is relatively high, the maintenance and conservation of flora still needs to be carried out intensively to maintain the stability of the water discharge of the Way Besai River. These results confirm that the vegetation around the Way Besai hydropower plant is still relatively sustainable, but sustainable conservation efforts are needed to control land conversion that has the potential to reduce the water discharge of the Way Besai River.

Abstract

Jamu is a traditional Indonesian drink derived from plants that are efficacious for use in efforts to maintain health and cure diseases. However, because the manufacturing process is still simple, jamu is at high risk of contamination by microorganisms such as fungi and pathogenic bacteria such as Escherichia coli and Salmonella sp. This study aims to determine the presence of Escherichia coli and Salmonella sp. Coliform contamination in Javanese turmeric herbal medicine sold in traditional markets. This study is based on the simple process of making jamu using hands, unclean clothes from jamu makers, and unclean processing areas, this will increase the risk of contamination and result in jamu being contaminated by microorganisms that can endanger consumer health. Data collection techniques use testing and counting of bacterial colonies with the TPC (Total Plate Count) method and Escherichia coli bacteria with the MPN (Most Probable Number) method which consists of presumptive test, confirmatory test and complementary test. The results of the analysis showed that in the TPC (Total Plate Count) test, three of the five samples, namely Sp 1, Sp 3, and Sp 4, showed results that were suitable for consumption because the TPC (Total Plate Count) value did not exceed the maximum limit of BPOM 2019 and two of the five samples, namely Sp 2 and Sp 5, showed results that were not suitable for consumption because they exceeded the maximum limit of BPOM 2019. These findings suggest that poor hygiene practices during jamu preparation can lead to contamination that threatens consumer health, emphasizing the need for improved sanitation control and standardized processing methods.

Abstract

Differences in organic matter content and soil pH can cause different fungal spore growth. Soil type is one of the factors that directly affect the presence of fungi. This research was conducted on the Wallace and Weber lines in Ternate, North Maluku. The research location was chosen because it has endemic fungal species, biodiversity that has not been widely discovered, and unique geographical conditions. Data collection was carried out through direct surveys using exploration methods, sampling with purposive random sampling, and direct collection of fungi based on shape, color, stem length, diameter, and type of substrate where they grow (soil, wood, leaves, and others), along with observations of fungal morphology. Qualitative analysis includes determining the order, family, genus, and scientific name presented in the form of tables and images, as well as descriptions of the characteristics of each species based on the identification results. The diversity index was also calculated. Environmental parameters measured included air temperature, soil moisture, light intensity, and soil pH. The results of the study showed that there were 20 species of fungi in the Moya Mabuku Hiking Trail Forest Area, Central Ternate District, Ternate City, North Maluku, Indonesia, with GPS coordinates of 0.8° North Latitude and 127.3630910° East Longitude. These fungi belong to the Ascomycota and Basidiomycota divisions, with the families Helotiaceae, Strophariaceae, Hygrophoraceae, Auriculariaceae, Omphalotaceae, Tremellaceae, Hypoxylaceae, Phyllotopsidaceae, Polyporaceae, Gardonemataceae, Tricholomataceae, Sarcoscyphaceae, Agaricaceae, Mycenaceae, Psathyrellaceae, and Cortinariaceae. The results of environmental parameter measurements on wood, soil, and coconut shell substrates showed that soil pH ranged from 3.85-6.10; air humidity 77.5-91.5% RH; substrate humidity 36.5-99.9%; Light intensity ranges from 93.5 to 7496 cd; air temperature ranges from 27.7 to 33.9°C; and substrate temperature ranges from 27.4 to 33.9°C. These pH conditions, ranging from 3.85 to 6.15, are considered optimal for supporting the growth of macroscopic fungi.

Abstract

The low critical thinking skills and student learning outcomes in science learning are still the main problems in schools. This study aims to determine the influence of the Project Based Learning (PjBL) learning model on the learning outcomes and critical thinking skills of grade VIII students on animal cell and plant cell materials at SMP Muhammadiyah 6 Samarinda. This study uses a quantitative method with a quasy experimental nonequivalent control group design. The sample totaled 50 students consisting of 25 students in the experimental class and 25 students in the control class. The research instrument is in the form of an essay test consisting of 10 questions. The results showed that the average post-test learning outcomes of the experimental class were higher (82.6) than the control class (59.2). In critical thinking skills, the experimental class obtained an average of 81.8 with the very good category, while the control class obtained 50.5 with the fair category. The results of the t-test showed a significant difference between the two classes (sig. < 0.05). Thus, the application of the Project Based Learning (PjBL) learning model can be recommended to improve critical thinking skills in science learning in junior high school.

Abstract

The decline in land spinach (Ipomoea reptans Poir.) production is partly due to pest attacks, such as armyworms, aphids, and whiteflies. This study aims to determine the effect of a combination of basil (Ocimum basilicum) and bay leaf (Syzygium polyanthum) leaf extract as a botanical pesticide on pest attack intensity and to determine the most effective concentration. This study used a Randomized Block Design (RBD) with five treatments (0%, 30%, 40%, 50%, and 60%) and five replications. The analysis results showed that the combination of the two leaf extracts significantly reduced pest attack intensity. The 60% concentration resulted in the lowest attack intensity, at 18% (mild category), making it the most effective treatment. Thus, the combination of basil and bay leaf extracts has the potential to be an environmentally friendly botanical pesticide for pest control in land spinach.

Abstract

Medicinal plants have long been utilized by the traditional community in Darek Village to treat various illnesses. One of the plant parts most commonly used for medicinal purposes is the leaf. Leaves exhibit diverse characteristics in terms of shape and size across different species. Leaf morphology includes features such as shape, color, size, venation pattern, leaf margin, leaf apex, leaf base, surface texture, and others. This study aims to identify the plant species whose leaves are used in traditional medicine by the Darek community and to describe the morphological characteristics of these medicinal leaves. This research employed a eksplorative descriptive approach using semi-structured interviews to document local knowledge regarding the use of medicinal plant leaves in Darek Village. Respondents were selected through a purposive sampling technique, involving community leaders and individuals recognized for their traditional knowledge of medicinal plants. The collected data were analyzed through data reduction, classification, and conclusion drawing to identify the plant species used medicinally and their leaf morphological traits. The findings indicate that the community utilizes 15 types of leaves from 13 plant families as traditional medicinal resources. In general, these medicinal plants display diverse leaf morphological characteristics, particularly in surface texture, venation type, and the shapes of the leaf margin, apex, and base. This morphological variation reflects the diversity of species employed and serves as a basis for the community to recognize and differentiate medicinal leaves. These findings highlight the richness of local knowledge, which holds potential for further development in ethnobotanical studies and the conservation of biological resources.

Abstract

The development of digital technology in the world has increased the ease of access to education. However, it also creates new challenges that affect stress levels and academic achievement. This study focuses on analyzing the influence of digital mindfulness techniques on the level of stress experienced by students of the Department of Biology Education at Lambung Mangkurat University, as well as their academic achievements. A descriptive-exploratory method with a qualitative research approach was applied in this study. Data was collected through an online survey filled out by 71 students and 5 lecturers, as well as interviews with 9 students from various generations. Data analysis was carried out using a descriptive method, based on students' views and experiences. The results show that most students experience moderate to high levels of academic stress, especially due to multitasking on digital platforms and high academic expectations. Nonetheless, the application of digital awareness techniques contributes to more effective time management and improved ability to concentrate. This research highlights that digital awareness is essential to maintain a balance between technology use and students' mental health. Scientifically, the results of this study show the importance of digital awareness in biology education for adaptive, healthy, and sustainable learning.

Abstract

Cemara Labat Village is a coastal area located in Kapuas Regency, Central Kalimantan which directly faces the Java Sea and borders Pelampai Village, Batola Regency, South Kalimantan. The village receives enough sediment from the Kapuas River to support the development of mangrove forests. For generations, the people of Cemara Labat Village have managed coastal resources, namely mangrove forests based on traditional traditions known as local wisdom. Mangrove forest vegetation experiences significant dynamics that are very important for the survival of various fauna in it, such as mammals (langurs and proboscis monkeys), fish, shrimp, insects, and even various types of birds. The purpose of this study is to describe the existence of proboscis monkeys based on the population of dominant mangrove species. The research was carried out for six months, from January - June 2025. Data were collected using observation and survey methods. For mangrove observation, it is carried out by making three Observation Sample Plots (PCP) measuring 20 x 500 m, while for proboscis monkey observation by making six observation stations that are made intentionally. Proboscis monkey observation starts at 06.00-18.00 WIB. The results showed INP ≥ 10% of the 6 species found, such as the White Flame (Avicennia marina (Forssk.) Vierh.) 199.99% are included in the medium category (101-200%), Black Flame (Avicennia alba Blume.) is 42.36%, Jeruju (Acanthus ilicifolius L.) is 17.07%, Piai (Acrostichum aureum L.) is 13.39%, Blind (Excoecaria agallocha L.) is 6.70%, and Plepotan (Derris trifoliate) is 5.90% in the low category (0-100%). Eight proboscis monkeys (Nasalis larvatus) were found in the area of the observed object. Although Avicennia spp. dominates the vegetation, the population of proboscis monkeys is relatively small, suggesting that Avicennia spp. mangroves are not the main feed crops for proboscis monkeys and only serve as a migration area.
