type: item
description: Exploration of soil microorganisms as biological control agents is one of the environmentally friendly approaches to controlling plant pests and diseases. This study aimed to explore and identify soil bacteria and fungi with potential as biological control agents at the Biological Control Laboratory of the Technical Implementation Unit for Food Crops and Horticultural Plant Protection, East Java. The research was conducted from January to April 2025 through bacterial isolation using the serial dilution method and fungal isolation using the baiting method, followed by macroscopic and microscopic observations as well as physiological and biochemical tests. The results showed that two soil bacterial isolates were obtained, in which one isolate was suspected to be Bacillus sp. with potential as a biological control agent, while the other isolate showed no potential as a biological control agent. A bacterial isolate initially suspected as Bacillus thuringiensis was not identified as an entomopathogenic bacterium based on physiological and biochemical tests. Fungal exploration resulted in isolates suspected as Trichoderma sp. and Aspergillus sp

KONDISI EKOSISTEM TERUMBU KARANG DI PERAIRAN PULAU TUNDA, BANTEN
type: item
description: A study on the condition of coral reef ecosystems was conducted at four observation sites in the waters of Tunda Island, Banten Province. This research aimed to collect data on the percentage cover of live hard corals, the number of coral colonies, the relative dominance of corals based on percentage cover and colony abundance, coral distribution, and the number and composition of coral species in the waters of Tunda Island. The study was designed to determine the percentage of coral cover and the overall condition of the coral reef ecosystem. The observation method used was the Line Intercept Transect method. The results showed that the condition of the coral reef ecosystem at the study sites, based on live hard coral cover, was categorized as moderate. The site with the highest coral cover was Timur (37.9%), while the lowest was Utara 1 (26%). A total of eight coral species were recorded, representing four families and six genera. Three species had the widest distribution: Goniastrea sp., Acropora nobilis, and Montipora capricornis. The species that most dominated based on percentage cover was Goniastrea sp. (relative dominance based on cover, DRt = 37.01%). This species also dominated in terms of colony abundance (relative dominance based on colonies, DRk = 70.9%). The highest similarity index was found between Utara 1 and Utara 3 (93%). Timur had the highest species richness, with seven species recorded. Utara 1 had the highest heterogeneity index (H’ = 1.62) and also the highest evenness index (J = 0.90).

EVALUASI KINERJA TRANSPLANTASI Acropora Sp. MENGGUNAKAN RAK BESI PADA KONDISI HIDRODINAMIKA MUSON DI GOSONG KALANGAN, LAMPUNG
type: item
description: Coral reef ecosystems in Gosong Kalangan waters are experiencing degradation, thereby requiring effective rehabilitation efforts, one of which is coral transplantation of Acropora sp. using artificial media in the form of iron racks. This study aimed to analyze the survival rate and growth rate of Acropora sp. fragments transplanted using this method. The research was conducted as a field experiment employing a Completely Randomized Design (CRD) over a six-month period (July to December 2025) at a depth of approximately ±4 meters. The main parameters observed were survival rate and linear growth of coral fragments. The results showed a decline in survival rate from 100% in the first month to 56% at the end of the observation period. In contrast, the surviving fragments exhibited an increase in average length from 9.4 cm to 14.64 cm (total growth of 5.39 cm), with a mean growth rate of 0.898 cm per month. The decrease in survival rate was presumably influenced by biotic pressure in the form of predation by Drupella sp., as well as abiotic disturbances related to hydrodynamic factors and monsoonal waves affecting the stability of the transplantation racks. The iron rack method was able to support the growth rate of Acropora sp. fragments; however, its effectiveness in maintaining survival is highly dependent on the stability of local environmental conditions.

type: item
description: Keamanan pangan sangat penting untuk melindungi kesehatan masyarakat, khususnya untuk produk pangan yang rentan terhadap kontaminasi mikroba. Kunyit bubuk curah yang dijual di pasar tradisional berisiko terkontaminasi jamur karena praktik penanganan yang tidak higienis, yang dapat mengurangi kualitas produk dan menimbulkan bahaya kesehatan. Penelitian ini bertujuan untuk mengetahui tingkat kontaminasi jamur pada kunyit bubuk curah yang dijual di Pasar Lubuk Buaya, Kota Padang, dan untuk mengidentifikasi karakteristik makroskopis jamur yang tumbuh. Penelitian ini dilakukan dari Oktober 2025 hingga Januari 2026 di Laboratorium Mikrobiologi, Departemen Biologi, Fakultas Matematika dan Ilmu Pengetahuan Alam, Universitas Negeri Padang. Desain penelitian deskriptif digunakan dengan metode pengambilan sampel purposif. Sampel kunyit bubuk curah dipilih dan dikumpulkan dari lima pedagang dengan tingkat kebersihan yang berbeda. Kontaminasi jamur dinilai menggunakan metode penghitungan kapang dan ragi (MYC) dengan teknik spread plate pada media Potato Dextrose Agar (PDA), diikuti dengan pengamatan makroskopis morfologi koloni jamur. Hasil menunjukkan bahwa semua sampel kunyit bubuk curah terkontaminasi jamur, dengan tingkat kontaminasi berkisar antara 2,67 × 10⁵ hingga 2,9 × 10⁶ CFU/g. Semua sampel melebihi batas maksimum yang diizinkan untuk kontaminasi mikroba sebagaimana ditetapkan oleh Badan Pengawas Obat dan Makanan Indonesia (BPOM). Jamur kontaminan yang diidentifikasi meliputi Aspergillus flavus, A. niger, Penicillium sp., dan ragi. Oleh karena itu, dapat disimpulkan bahwa kunyit bubuk curah yang dijual di Pasar Lubuk Buaya, Kota Padang, tidak memenuhi standar keamanan pangan mikrobiologis.

Adaptasi Struktur Histologi Insang Ikan pada Berbagai Kondisi Lingkungan: Kajian Literatur
type: item
description: Gills are vital organs in fish that function in respiration, osmoregulation, and ionic balance, making them highly sensitive to variations in environmental habitat conditions. Differences in water characteristics, such as water quality, dissolved oxygen, temperature, pH, and pollution levels, affect the structure and histological condition of the gills. This article aims to critically review and synthesize the structure and histological adaptations of fish gills in response to differences in habitat conditions through a literature review approach of reputable national and international publications. The results of the synthesis indicate that variations in environmental conditions trigger distinctive histological changes, including epithelial hyperplasia and hypertrophy, increased mucus and chloride cells, secondary lamella fusion, edema, and changes in vascularization, which reflect physiological adaptation mechanisms as well as early indicators of structural disorders due to environmental stress. Thus, the histological characteristics of fish gills have high potential to be used as biological biomarkers in assessing the quality of aquatic habitats and the health of aquatic ecosystems, as well as as a basis for the development of sustainable environmental biomonitoring.

AKTIVITAS ANTIMIKROBA BAKTERI ENDOFIT (Pseudomonas Berfluoresen) DARI AKAR PISANG BUAI (Musa x paradisiaca L.)
type: item
description: Infectious diseases caused by pathogenic bacteria and fungi remain a global health problem, particularly due to the increasing incidence of antimicrobial resistance, highlighting the need for effective alternative antimicrobial sources. Endophytic bacteria, especially fluorescent Pseudomonas, are known to produce secondary metabolites with antibacterial and antifungal properties. This study aimed to evaluate the antimicrobial activity of endophytic fluorescent Pseudomonas isolated from the roots of banana buai (Musa × paradisiaca L.) and to identify isolates with the highest activity. This experimental study employed a Completely Randomized Design (CRD) using 44 isolates with three replications. Antimicrobial activity was tested in vitro using the spot inoculation method against Escherichia coli, Staphylococcus aureus, and Candida albicans. The observed parameter was the diameter of the inhibition zone, which was analyzed using analysis of variance (ANOVA) followed by Duncan’s Multiple Range Test. The results showed that antimicrobial activity varied among isolates and was specific to the test microorganisms. Isolate PFPB 32 exhibited the highest activity against E. coli and S. aureus, while isolate PFPB 300 showed the strongest antifungal activity against C. albicans. These findings indicate that endophytic fluorescent Pseudomonas from banana buai roots have potential as a source of antimicrobial agents, particularly antifungal agents against Candida albicans

DEVELOPMENT OF ECTA-T AND EMIS-T WITH A COMBINATION OF THREE-TIER AND CERTAINTY RESPONSE INDEX METHODS IN ENVIRONMENTAL CONCEPT
type: item
description: Environmental pollution is a problem that often occurs in the environment where we live, and requires the ability to think creatively to be able to solve it. The ability to think creatively in solving environmental problems is determined by their knowledge related to ecology. Therefore this study aims to create an instrument that can measure students' misconceptions (EMis-T) in ecological material and an instrument that can measure students' creative thinking skills (ECTA-T) in solving environmental problems. The research was conducted with reference to the Research and Development (R&D) method with the Borg & Gall (2003) development model which was modified into four development steps, including: (1) Preliminary study stage; (2) Development stage; (3) validation and trial stage; (4) Application Stage. The type of instrument developed is in the form of an essay type written test by combining the three tier test type and certainty response index. The objects that were used as targets for the development of this instrument were class X senior high school. Based on the results of the analysis it is known that the product that has been developed has valid criteria, medium high reliable value, no discriminating power which has a negative value, and questions that have an easy level of difficulty do not dominate, so this product can be used by educators to measure creative thinking skills and students' misconceptions about environmental material. The identified level of students' creative thinking ability was dominated by students in the high category. While the level of students' misconceptions that were identified were dominated by students in the low category.

KEANEKARAGAMAN KEPITING BIOLA (Uca SPP.) DI EKOSISTEM MANGROVE TONGKE- TONGKE SINJAI TIMUR KABUPATEN SINJAI
type: item
description: Penelitian ini bertujuan untuk menilai keanekaragaman kepiting biola (Uca spp.) di kawasan mangrove Tongke-Tongke, Sinjai Timur. Pengambilan sampel dilakukan di empat stasiun pengamatan menggunakan pengamatan langsung yang dikombinasikan dengan teknik pengambilan sampel bertujuan. Hasil penelitian menunjukkan adanya tiga spesies kepiting biola, yaitu Uca rosea, Uca perplexa, dan Uca jocelynae, yang tersebar tidak merata di seluruh stasiun pengamatan. Analisis indeks ekologi menunjukkan keanekaragaman spesies yang rendah di Stasiun I (H' = 1,07) dengan keseragaman yang tinggi (E = 0,97), sedangkan Stasiun II juga menunjukkan keanekaragaman yang rendah (H' = 0,61) tetapi dengan keseragaman yang sedang (E = 0,55). Tidak ditemukan kepiting biola di Stasiun III dan IV, yang terletak di dekat permukiman penduduk dan kawasan ekowisata. Parameter lingkungan yang diukur meliputi suhu (29,96–30,94 °C), pH (7,4–7,5), salinitas (26,5–27,6‰), oksigen terlarut (DO; 5,29–6,0 mg/L), dan jenis substrat mulai dari lempung berpasir hingga lempung liat berpasir. Temuan ini menunjukkan bahwa keberadaan kepiting biola dapat berfungsi sebagai bioindikator kesehatan ekosistem mangrove, dengan distribusinya sangat dipengaruhi oleh karakteristik substrat dan kondisi lingkungan, terutama di daerah yang mengalami gangguan antropogenik minimal.

PERAN ORGANISME SESSILE SEBAGAI BIOINDIKATOR MIKROPLASTIK DI EKOSISTEM PESISIR: SYSTEMATIC LITERATURE REVIEW
type: item
description: Microplastics have emerged as pervasive contaminants in coastal ecosystems and can accumulate in sessile organisms, particularly bivalves, through filtration mechanisms. This study aims to synthesize existing evidence on microplastic concentration, characteristics, polymer types, and identification methods in sessile organisms using a systematic literature review (SLR) approach. Literature selection was conducted following the PRISMA guidelines, with inclusion criteria limited to primary research articles published between 2015 and 2025. The synthesis results indicate that microplastics are consistently detected in sessile organisms, with concentrations varying among species and locations. Fibers represent the dominant microplastic shape, followed by fragments, while particle sizes are generally within smaller microplastic classes that exhibit high bioavailability. The most frequently identified polymer types include polyethylene (PE), polypropylene (PP), and polyethylene terephthalate (PET), suggesting predominantly anthropogenic sources associated with domestic and fisheries-related activities. Across all reviewed studies, microplastic identification was primarily performed using spectroscopic techniques, particularly Fourier Transform Infrared Spectroscopy (FTIR) and its variants, which enable accurate polymer determination. Overall, this review highlights the potential of sessile organisms as effective bioindicators of microplastic pollution in coastal environments and underscores the need for standardized analytical methods to improve data comparability across studies.

PENDEKATAN HISTOLOGI INSANG DAN HATI IKAN NILA (Oreochromis niloticus) SEBAGAI BIOINDIKATOR KUALITAS PERAIRAN ALAMI DI INDONESIA: LITERATUR REVIEW
type: item
description: The quality of freshwater in Indonesia has declined due to increasing anthropogenic pressures, particularly from heavy metals, agricultural waste, and industrial waste. A bioindicator approach based on the biological response of aquatic organisms is needed to complement conventional water quality monitoring. This review article aims to examine changes in the histology of the gills and liver of tilapia (Oreochromis niloticus) as a bioindicator of freshwater quality in Indonesia. The method used was a literature review of scientific articles obtained from Google Scholar, Garuda, and ScienceDirect. Articles were selected based on the suitability of the research location in Indonesia, the use of tilapia as the object, and the histological analysis of the gills and/or liver. The results of the review show that water pollution in Indonesian lakes and rivers, especially by heavy metals and anthropogenic activities, consistently causes histological changes in the gills and liver of tilapia. The dominant lesions in the gills included hyperplasia, edema, lamella fusion, epithelial lifting, and telangiectasis, while in the liver, fatty degeneration, hydropic degeneration, cytoplasmic vacuolation, karyolysis, and karyorrhexis were found. These patterns of change reflect the cause-and-effect relationship between the type and intensity of pollutants and the degree of tissue damage. These findings confirm that the histological approach to tilapia gills and liver has strong potential as a biological bioindicator in monitoring and sustainable management of freshwater quality in Indonesia.

KEMAMPUAN PSEUDOMONAS BERFLUORESEN SEBAGAI AGEN ANTAGONIS TERHADAP Ralstonia solanaceaerum PENYEBAB LAYU TANAMAN NILAM (Pogestemon cablin Benth)
type: item
description: Patchouli (Pogestemon cablin Benth) is a cultivated plant that can produce oil and generate income for farmers. However, attacks by plant pests (OPT) often pose a challenge to patchouli production in Indonesia. One organism that causes wilt disease in patchouli plants is the bacterium Ralstonia solanaceaerum. Therefore, more environmentally friendly and sustainable control methods are needed. One strategy is the use of biological agents, especially antagonistic rhizosphere bacteria such as fluorescent pseudomonas. This study was conducted from June to August 2025 at the Plant Physiology Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences, Padang State University. This study used a completely randomized design (CRD) as the experimental design. In this study, there were 6 treatments (different isolates), each repeated 3 times. The parameter observed was the formation of an inhibition zone using the disc diffusion method. The data were analyzed using analysis of variance (ANOVA). If there were significant differences, Duncan's New Multiple Range Test (DNMRT) was used at a 5% level. Based on the results and discussions, it can be concluded that all fluorescent Pseudomonas isolates tested have the ability to inhibit R. solanaceaerum, the cause of wilt disease in patchouli plants. The isolate with the best ability to inhibit the growth of R. solanaceaerum on patchouli plants was isolate Pf S36 with an inhibition zone of 20.37 mm, but there was no significant difference between the other isolates because the inhibition effectiveness was relatively uniform.

EKSPLORASI JENIS DAN PEMANFAATAN TANAMAN ENDEMIK DAN LOKAL DI KECAMATAN BOGOR SELATAN
type: item
description: South Bogor District is an area with agroecosystem conditions that still support the existence of endemic and local plant species utilized by local communities. However, scientific information regarding species diversity, utilization patterns, and sustainability potential remains limited. This study aimed to explore the diversity of endemic plants, their utilization forms, plant parts used, as well as community perceptions and threats to their existence in South Bogor District. The research employed a descriptive survey method with an ethnobotanical approach through field observations and semi-structured interviews with local residents. The results revealed various endemic and local plant species utilized by the community, predominantly for medicinal purposes, food, and spices. The most frequently used plant parts were fruits, leaves, and rhizomes, with processing methods that remain simple and based on traditional knowledge. Community perception toward the importance of endemic plants was highly positive; however, high utilization intensity of certain species was not always aligned with their availability in nature. Major threats to the sustainability of endemic plants include land-use change, logging, inadequate plant maintenance, and limited replanting efforts. This study highlights that endemic plants in South Bogor District play essential ecological, social, and cultural roles, yet require community-based management and conservation strategies to ensure their sustainable utilization.

ANALISIS KEBUTUHAN LKM UNTUK MENDUKUNG PENINGKATAN LITERASI SAINS PADA PEMBELAJARAN BIOLOGI MURID SMA/MA
type: item
description: Scientific literacy is an essential twenty-first century skill that supports students in thinking critically and understanding scientific phenomena in everyday life. However, the level of scientific literacy among Indonesian students remains relatively low. This study aimed to analyze the need for Student Worksheets to support the improvement of scientific literacy in biology learning for eleventh-grade senior high school students. This research employed a descriptive method with data collected through student observation questionnaires, scientific literacy questionnaires, biology teacher interviews, and analysis of student’s biology test scores. The results indicate that although student questionnaire responses suggested moderate to high levels of scientific literacy, interview findings and academic performance data revealed that students’ actual scientific literacy was still low. Therefore, the development of scientific literacy-oriented worksheets is needed to enhance biology learning and scientific literacy effectiveness.
