Analisis Produksi Biolistrik oleh Aneurinibacillus thermoaerophilus Strain N25 pada Variasi Konsentrasi Starter dalam Sistem Microbial Fuel Cell (MFC)
type: item
description: The increasing demand for electrical energy drives the development of renewable energy technologies such as Microbial Fuel Cell (MFC), which converts organic substrates into electricity using microorganisms. This study aims to determine the effect of starter concentration and identify the optimal concentration of Aneurinibacillus thermoaerophilus strain N25 in bioelectricity production. An experimental method was used with a dual-chamber MFC system and starter concentrations of 3%, 6%, 9%, 12%, and 15%. Voltage production was measured using a digital multimeter (V) over 24 hours. The results showed that starter concentration affected bioelectricity production, with voltage increasing over time and reaching a peak at the 20th hour. Higher starter concentrations produced higher voltage due to increased microbial activity and more efficient electron transfer.

description: Peningkatan kebutuhan energi berkelanjutan telah menunutut pengembangan Microbial Fuel Cell (MFC) sebagai teknologi alternatif. Penelitian ini bertujuan untuk menganalisis pola produksi listrik Bacillus licheniformis strain KGEB16 yang diamobilisasi pada sistem Microbial Fuel Cell (MFC). Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan perlakuan variasi konsentrasi natrium alginat (2%, 3%, 4%, 5%, dan 6%) serta lima ulangan. Proses amobilisasi sel dilakukan dengan metode entrapment menggunakan natrium alginat, sedangkan pengukuran tegangan listrik dilakukan setiap 2 jam selama periode inkubasi 24 jam. Data yang diperoleh dianalisis menggunakan uji ANOVA dan dilanjutkan dengan uji Duncan (Duncan Multiple Range Test/DMRT) pada taraf signifikansi 5%. Hasil penelitian menunjukkan bahwa pola produksi listrik mengalami peningkatan secara bertahap sejak awal inkubasi hingga mencapai puncak pada jam ke-20, kemudian menurun pada jam ke-22 hingga 24. Tegangan tertinggi diperoleh pada konsentrasi natrium alginat 5%, sedangkan tegangan terendah diperoleh pada konsentrasi 2%. Dengan demikian, dapat disimpulkan bahwa konsentrasi natrium alginat berpengaruh signifikan terhadap pola produksi listrik, dengan konsentrasi optimum sebesar 5% pada sistem MFC.

PENGARUH ISOMETRIC HANDGRIP EXERCISE TERHADAP PERUBAHAN TEKANAN DARAH PADA LANSIA PENDERITA HIPERTENSI
type: item
description: Hypertension or high blood pressure is one of the main health problems in the elderly that risks reducing the quality of life and increasing morbidity and mortality. Hypertension management efforts can be done pharmacologically and non-pharmacologically, one of which is by doing isometric handgrip exercise. This study aims to determine the effect of isometric handgrip exercise and its frequency on changes in blood pressure in elderly people with hypertension in X Village, Madiun Regency. This type of research uses a pre-experimental design with a one-group pretest-posttest design approach. The population of this study was elderly people with hypertension in X Village, Madiun Regency. The sample amounted to 18 respondents selected using a simple random sampling technique. Data were collected by measuring blood pressure before and after being given isometric handgrip exercise intervention for 5 consecutive days, then analyzed using the Wilcoxon signed rank test. The results showed that the average systolic blood pressure before the intervention was 151.67 mmHg and after the intervention became 133.33 mmHg, while the average diastolic blood pressure before the intervention was 91.67 mmHg and after the intervention became 77.78 mmHg. The results of the Wilcoxon test obtained a ρ-value = 0.000 (p < 0.05), which means there is a significant effect of isometric handgrip exercise on changes in blood pressure in elderly people with hypertension. This study shows that isometric handgrip exercise is effective in lowering blood pressure in elderly people with hypertension. This exercise can be used as a simple, safe, inexpensive, and easy to do non-pharmacological intervention independently at home.

POTENSI Bacillus licheniformis strain Nam 2-2 DALAM PRODUKSI BIOLISTRIK PADA VARIASI pH
type: item
description: The increasing global energy demand has encouraged the development of sustainable alternative energy sources such as Microbial Fuel Cells (MFCs). This study aimed to determine the optimum pH for bioelectricity production using Bacillus licheniformis strain Nam 2-2 in a dual-chamber MFC system. The experiment employed a completely randomized design with pH variations of 7, 7.5, and 8. Voltage output was measured every 2 hours over a 24-hour incubation period. The results showed that bioelectricity production increased over time, reached a peak at 16–20 hours, and then declined. The highest voltage was observed at pH 7.5, reaching 0.782 mV, followed by pH 8 (0.758 mV) and pH 7 (0.748 mV). These findings indicate that slightly alkaline conditions are more favorable for microbial activity and electron transfer efficiency. Therefore, pH optimization is essential to improve MFC performance and supports its potential as a renewable energy source.

Optimasi Primer : Suhu Annealing untuk Deteksi Gen Matrix Virus Influenza A Menggunakan Polymerase Chain Reaction (PCR)
type: item
description: Influenza A virus (IAV) is a pathogen that attacks the respiratory tract in humans and animals, which can be a threat to public health. This virus has a number of genes that are targeted by PCR for diagnostic detection purposes, one of which is the matrix gene. Detection of the matrix gene in the Influenza A virus from DNA/RNA genetic material can be done using the polymerase chain reaction (PCR) technique. One of the stages that determines the success of the PCR process is the annealing stage, for which the optimum temperature and cycle are required for primer attachment in the annealing stage. This research is a descriptive study towards an experiment conducted in June 2025 at the Bacteriology Laboratory of the Research and Innovation Agency (BRIN) KST. Soekarno Cibinong. The results obtained showed that the optimum temperature for matrix gene amplification in the Influenza A virus using the forward primer FluAV M-U44 and reverse primer FluAV M-L287 was 53.5 °C, 54 °C, and 54,5 °C and 35 cycles were evidenced by the formation of a fairly bright band in the electrophoresis results.

HUBUNGAN SIKAP IBU DENGAN KEJADIAN UNDERWEIGHT PADA BALITA DI WILAYAH KERJA PUSKESMAS COT SEUMEURENG
type: item
description: Good nutritional status in toddlers is essential for child health and development. Nationally, the prevalence of underweight among children under five in Indonesia is 15.9%, consisting of 3.0% severely underweight and 12.9% underweight, while 84.1% of toddlers have normal nutritional status. At the provincial level, Aceh shows a higher prevalence of underweight at 22.6%, including 4.9% severely underweight, 17.7% underweight, and 77.4% with normal nutritional status. At the district level, data from the Aceh Barat Health Office in 2024 recorded 530 cases of underweight, with the highest distribution in the working areas of Cot Seumeureung Health Center (85 cases), Kuala Bhee Health Center (84 cases), and Johan Pahlawan Health Center (83 cases).This condition highlights the importance of the mother’s role, particularly maternal attitudes toward fulfilling toddlers’ nutritional needs. This study aimed to analyze the relationship between maternal attitudes and the incidence of underweight among toddlers in the working area of Cot Seumeureung Health Center. A quantitative cross-sectional design was used, involving 63 mothers of children aged 0–59 months from three villages through total sampling. Data were collected from November to December 2025 using questionnaires, interviews, and anthropometric measurements based on WHO weight-for-age (WFA) z-score standards, and analyzed using the chi-square test (α = 0.05). The results showed that most mothers had positive attitudes toward toddler nutrition, and there was a significant relationship between maternal attitudes and the incidence of underweight (p = 0.040). In conclusion, maternal attitudes play an important role in determining toddlers’ nutritional status; therefore, underweight prevention efforts should focus on fostering positive attitudes, appropriate feeding practices, and strengthening continuous nutrition education and assistance through integrated health posts (posyandu) and health workers.

PENGARUH PEMANFAATAN LIMBAH CANGKANG TELUR AYAM SEBAGAI BIOFERTILIZER TERHADAP PERTUMBUHAN KACANG TANAH (Arachis hypogaea L.)
type: item
description: This research explores the potential of chicken eggshell waste as an alternative biofertilizer to reduce dependence on synthetic chemical fertilizers, which often trigger land degradation. The main focus of this study was to analyze the extent to which eggshell powder application affects the vegetative phase of peanut (Arachis hypogaea L.) plants, while also determining the most responsive application dose. The experiment was conducted with a four-stage treatment design: P0 (control), P1 (133.3 g/polybag), P2 (200 g/polybag), and P3 (266.6 g/polybag). Parameters observed included plant height dynamics and leaf productivity. The results showed that the integration of eggshell biofertilizer significantly stimulated plant growth compared to the control. The P3 dose (266.6 g/polybag) was identified as the most effective treatment, with an average plant height of 26 cm and 32 leaves at the end of the observation period. Interestingly, at the intermediate dose (P2), there was evidence of inhibition of stem elongation despite the high leaf count. This phenomenon is thought to be related to nutritional imbalances caused by excess calcium (Ca), which inhibits the absorption of other essential micronutrients. Overall, this study confirms that the use of eggshell waste not only serves as a natural source of calcium carbonate (CaCO₃) for soil pH stabilization but is also effective in sustainably improving the agronomic performance of peanuts.

type: item
description: Kelapa sawit merupakan salah satu komoditas perkebunan yang memiliki peranan penting dalam perekonomian Indonesia. Namun, produktivitas tanaman kelapa sawit sering terganggu oleh serangan hama, salah satunya adalah Oryctes rhinoceros yang dikenal sebagai kumbang tanduk. Penelitian ini bertujuan untuk menganalisis penerapan prinsip bioetik dalam Standar Operasional Prosedur (SOP) pengendalian hama Oryctes rhinoceros pada perkebunan kelapa sawit di PT. Socfin Indonesia Kebun Bangun Bandar. Penelitian ini menggunakan pendekatan kualitatif dengan metode observasi langsung dan wawancara terhadap pekerja di lapangan. Hasil penelitian menunjukkan bahwa penerapan SOP pengendalian hama telah dilaksanakan dengan baik melalui penggunaan alat pelindung diri serta prosedur penyemprotan yang terstruktur. Penerapan tersebut mencerminkan prinsip bioetik terutama dalam aspek keselamatan kerja dan tanggung jawab terhadap lingkungan. Namun demikian, pemahaman pekerja terhadap konsep bioetik masih terbatas karena sebagian besar pekerja hanya memahami SOP sebagai aturan kerja. Oleh karena itu, diperlukan peningkatan sosialisasi dan pelatihan terkait bioetik agar penerapan SOP dapat dilakukan secara lebih optimal dan berkelanjutan.

Pengaruh Dosis Pupuk Organik Cair FloraOne® Terhadap Pertumbuhan Tanaman Tomat (Solanum lycopersicum L.)
type: item
description: Tomato plants (Solanum lycopersicum L.) are horticultural commodities that have high nutritional value and economic value and are widely needed by the community. The increase in demand for tomatoes needs to be balanced with efforts to increase production through proper cultivation techniques, one of which is through fertilization. The continuous use of inorganic fertilizers can reduce soil fertility and negatively impact the environment, so a more environmentally friendly fertilization alternative, such as the use of liquid organic fertilizer (POC), is needed. FloraOne® liquid organic fertilizer contains nutrients and microorganisms that have the potential to support plant growth. This study aims to determine the effect of applying FloraOne® liquid organic fertilizer on the growth of tomato plants. The research was carried out using an experimental method with a Complete Random Design (RAL) consisting of seven FloraOne® concentration treatments, namely P0 (control), P1 (0.1%), P2 (0.2%), P3 (0.3%), P4 (0.4%), P5 (0.5%), and P6 (0.6%) with four replicates. The observed parameters included plant height, stem diameter, wet weight, dry weight, and flowering age. The data was analyzed using the Analysis of Variance (ANOVA) test at a significance level of 5%. The results showed that the application of FloraOne® liquid organic fertilizer did not have a significant effect on the height, diameter, wet and dry weight of tomato plants (p>0.05) while P3 and P6 showed the appearance of flowers in the 8th week. However, descriptively, the 0.3% concentration treatment showed a better growth tendency than the other treatments.

KAJIAN LITERATUR MIKROSTRUKTUR SISIK IKAN DALAM STUDI TAKSONOMI IKAN
type: item
description: Taksonomi ikan umumnya menggunakan pendekatan morfometri dan meristik dalam proses identifikasi spesies, namun metode tersebut memiliki keterbatasan pada spesies yang berkerabat dekat dan memiliki kemiripan morfologi eksternal. Kajian ini bertujuan menelaah peran mikrostruktur sisik sebagai karakter taksonomi pendukung dalam studi identifikasi ikan. Penelitian dilakukan melalui metode systematic literature review terhadap berbagai publikasi ilmiah yang membahas analisis mikrostruktur sisik menggunakan mikroskop cahaya dan scanning electron microscope (SEM). Hasil kajian menunjukkan bahwa komponen mikrostruktur seperti fokus, circuli, radii, lepidont, tubercle, ctenii, serta struktur canal lateral memiliki variasi yang konsisten antarspesies maupun antar lokasi sisik pada tubuh ikan. Perbedaan karakter tersebut terbukti mampu membedakan spesies yang secara morfologi makroskopis sulit dipisahkan, serta sejalan dengan data kekerabatan molekuler. Selain pada ikan modern, mikrostruktur sisik fosil juga dapat digunakan untuk interpretasi paleoekologi dan estimasi umur. Dengan demikian, analisis mikrostruktur sisik berpotensi menjadi karakter taksonomi pelengkap yang penting dalam memperkuat sistem identifikasi dan klasifikasi ikan.

NARRATIVE REVIEW: POTENSI EKSTRAK BAWANG PUTIH (Allium sativum) DALAM MENINGKATKAN PERTUMBUHAN LACTOBACILLUS DAN MENGHAMBAT BAKTERI PENYEBAB DIARE
type: item
description: Diarrhea is a global health challenge exacerbated by increasing antibiotic resistance. This narrative review aims to analyze the potential of garlic extract (Allium sativum) as a natural synbiotic agent in supporting Lactobacillus growth while suppressing enteric pathogens. The method used was a narrative review with systematic literature searches through the Google Scholar and PubMed databases. The synthesis results show that garlic contains allicin and fructooligosaccharide (FOS) compounds at 3.34% w/w, which are effective in inhibiting pathogenic bacteria such as Escherichia coli and Salmonella spp., and are able to stimulate the growth of Lactobacillus acidophilus optimally at a concentration of 4%. In conclusion, Allium sativum has dual potential as an antibacterial agent and prebiotic, whose effectiveness is influenced by concentration and extraction method. Further research is needed to standardize the dosage for clinical application.

GENOME EDITING BERBASIS CRISPR-CAS9 UNTUK MENINGKATKAN TOLERANSI STRES ABIOTIK PADA TANAMAN PADI (ORYZA SATIVA): A SYSTEMATIC LITERATURE REVIEW
type: item
description: Abiotic stresses such as drought, salinity, extreme temperatures, and oxidative stress are major factors limiting the growth and productivity of rice plants. The development of CRISPR-Cas9-based genome editing technology provides a new, more precise approach to modifying genes that play a role in plants' adaptive responses to environmental stresses. This study aims to synthesize the development of genome editing research in rice plants, focusing on the identification of target genes, genome editing strategies, and their impact on increasing abiotic stress tolerance. The method used is a systematic literature review of research articles published in international scientific journals. A total of 31 articles were analyzed in the literature review process, and 22 articles that explicitly reported target genes and genome editing strategies were used in the main synthesis. The results of the analysis showed that most studies targeted regulatory genes that play a role in regulating stress responses, especially groups of transcription factors such as NAC, DREB, bZIP, MYB, and WRKY. In addition, several studies also targeted genes related to ion homeostasis, hormonal signaling pathways, secondary metabolism, and antioxidant systems. The most dominant genome editing strategy was gene knock-out through CRISPR-Cas9-based mutations, while several recent studies have begun to apply multiplex genome editing to target more than one gene simultaneously. Genome-edited rice plants generally show increased tolerance to various abiotic stresses through improved ion homeostasis, increased water use efficiency, cell membrane stability, and strengthened antioxidant systems. These findings indicate that CRISPR-Cas9 is a precision genome engineering approach with the potential to support the development of rice varieties that are more adaptive to environmental changes.

title: EXPLORATION AND IDENTIFICATION OF MICROBES AND FUNGI FROM SOIL SAMPLES OF GUNGGUNG VILLAGE, BATUAN DISTRICT, SUMENEP REGENCY AS BIOLOGICAL CONTROL AGENTS AT THE EAST JAVA FOOD CROPS AND HORTICULTURE PLANT PROTECTION LABORATORY
description: Soil microorganisms play an essential role in maintaining soil fertility and suppressing plant pathogens, making them potential biological control agents in sustainable agriculture. This study aimed to explore and identify microbes and fungi from soil samples collected from yellow Kepok banana (Musa spp.) plantations in Gunggung Village, Batuan District, Sumenep Regency, as potential biological agents. The novelty of this research lies in the exploration of untreated Fusarium-infected banana plantation soil to obtain indigenous microbial isolates with biocontrol potential. A descriptive exploratory research design was employed. Bacterial isolation was conducted using the serial dilution method on Potato Dextrose Agar (PDA), followed by purification, macroscopic and microscopic characterization, 5% KOH test, soft rot test, and hypersensitivity test. Fungal isolation was performed using the baiting method with coconut, rice, and mealworms as substrates, followed by morphological identification. The results revealed the presence of Bacillus sp. as the dominant bacterial isolate, characterized by circular colonies, yellowish-white color, Gram-positive reaction, and rod-shaped cells. Soft rot and hypersensitivity assays indicated varying pathogenic responses among isolates. Fungal identification showed the presence of Aspergillus sp. (brownish-green, powdery colonies) and Penicillium sp. (yellowish-green, granular colonies). These findings indicate that soil from the study site contains microbial populations with potential applications as biological control agents. The study highlights the importance of exploring indigenous soil microorganisms to support environmentally friendly plant disease management and sustainable agricultural practices.

A sample of 42 eleventh-grade students from MAS Al-Ihsan Pandeglang was divided into an experimental group, which used video media, and a control group, which used conventional methods. Data were collected through motivation questionnaires and multiple-choice tests. The results showed that the experimental group achieved a significantly higher average N-Gain score of 56.50%, compared to 21.25% for the control group. Furthermore, student motivation was high, with 93.21% of students exhibiting a positive attitude toward the use of learning videos. In conclusion, the use of biology learning videos significantly enhances both student motivation and learning outcomes regarding the circulatory system materiallearning outcomes and motivation compared to conventional methods.

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
