Abstract

Euglena sp. contains several metabolites that play a role in various sectors, likely biofuels, food, feed, and pharmaceuticals. Multiple treatments are required to increase the content of Euglena sp.to support its use. In this study, a chemical stimulant in the form of lignosulfonate was added to Euglena sp. in order to increase its natural potency as measured by lipid, carbohydrate, protein, paramylon content, and biomass productivity. Lignosulfonate is a macromolecular polyelectrolyte and anionic surfactant that is unique and multifunctional. This lignosulfonate can act as an emulsifier, dispersing agent, binder, and stabilizer of lipids in Euglena sp. cells. In addition to the lignosulfonate chemical stimulator, it can affect the growth process of Euglena sp. so that it can produce good-quality cells. The method used was a Completely Randomized Factorial Design (CRD) with three treatments and three replications. The results obtained indicated that the addition of lignosulfonate was significantly changed the cell and protein density tests. Therefore, the optimal concentration of lignosulfonate can be used as an agent to increase the growth rate and metabolites of Euglena sp. significantly.Keywords:BiofuelEuglena sp.Growth rateslignosulfonateMetabolites

Abstract

The application of Euglena as a carbon capture organism has generated considerable interest among scientists. Through the photosynthesis process, many kinds of metabolites are produced by Euglena, such as lipids, proteins, and pigments. Due to the metabolites produced by Euglena, it is vital to optimize the carbon capture ability and cell growth rate by adding Zn2+ content and giving photoperiodic into Euglena culture. The purpose of this study is to identify the optimal photoperiod and Zn2+ concentration to increase the growth rate, biomass, and metabolite content of Euglena sp. This study is a laboratory experiment involving the cultivation of Euglena sp. in various photoperiod cycles (light:dark), namely 24:0, 12:12, 14:10, and 16:8. In addition, Euglena sp. was also cultivated using different concentrations of Zn2+ (0 ppm, 5 ppm, 10 ppm, and 15 ppm). The growth of Euglena sp. was monitored for 18 days before being harvested every three days to measure the research parameters, including primary and secondary metabolites. The results showed that the photoperiod treatment and various concentrations of Zn2+ had a significant impact (P<0.05) on the growth rate, biomass, lipid, carbohydrate, protein, chlorophyll, and carotenoid levels of Euglena sp.

Abstract

One of the elements that has the biggest impact of air pollution is lead. Lead can be contaminated through the air, one of which is produced by burning vehicles and releasing lead oxide in the form of dust or particles that can be inhaled into the human respiratory tract. The duration of lead exposure affects air pollution which can harm human health. The aim of this research was to determine blood lead levels in truck drivers in a section of Marunda terminal North Jakarta using the ICP-MS method. ICP-MS has multi-element analysis capabilities and high sensitivity compared to other techniques. This type of research is quantitative descriptive with a cross-sectional research design and data collection using purposive sampling, data collection was carried out in June 2023. Lead examination was carried out at the DKI Jakarta Regional Health Laboratory. The type of specimen used is human blood. Blood samples were collected using an EDTA tube and then measured using an ICP-MS device. The results showed that 17 respondents had lead levels < 2.28 µg/L. Blood lead levels in truck drivers in a section of Marunda terminal North Jakarta were not detected. This shows that there is no lead content in the blood.

Abstract

The persistent issue of low critical thinking skills among students in physics education highlights the limitations of traditional teaching methods, which often emphasize memorization over analytical and evaluative thinking. This study investigates the impact of Case-Based Learning (CBL) on improving critical thinking skills, focusing on six indicators: interpretation, analysis, evaluation, inference, explanation, and self-regulation. Conducted at SMA Negeri 1 Kediri, Lombok, Indonesia, the study employed a quasi-experimental pretest-posttest control group design. The experimental group received CBL instruction, while the control group was taught using conventional methods. Data collection involved written essay tests scored using a rubric adapted from the Ennis-Weir Critical Thinking Essay Test, with results analyzed through both descriptive and inferential statistics. Descriptive analysis calculated means, standard deviations, and normalized gains (n-gain), revealing significant improvements in the experimental group across all critical thinking indicators, with n-gain scores categorized as high. Inferential statistical analysis using paired and independent sample t-tests confirmed significant differences in critical thinking skill development between the experimental and control groups. The findings demonstrate that CBL fosters critical thinking by engaging students in real-world scenarios, promoting collaboration, and encouraging reflective reasoning. This study concludes that CBL is an effective pedagogical strategy for addressing critical thinking deficiencies in physics education, bridging the gap between theoretical understanding and practical application. The implications suggest integrating CBL into curricula to enhance students’ cognitive skills, equipping them for academic and professional challenges. Future research should explore CBL’s long-term impacts and adaptability to various subjects and educational contexts, ensuring its broader implementation as a transformative teaching approach.

Abstract

Light quality critically modulates the physiology of diatoms, influencing photosynthetic efficiency and metabolite synthesis. This study examines how monochromatic red (620–750 nm) or blue (450–495 nm) light affects the biochemical profiles and pigment production in Navicula sp. versus white light (control). Cultures were grown in sterile f/2 medium, and biomass was tracked via OD680. Biochemical analyses included lipids (Bligh and Dyer method), carbohydrates (phenol-sulfuric acid assay), proteins (Bradford assay), and pigments (spectrophotometric quantification). The growth dynamics were modeled using logistic and Gompertz equations. No significant differences in OD-based growth rates, carbohydrates, proteins, or lipids content were observed with red or blue light compared with the control. However, blue light elevated chlorophyll a levels 4-fold and maximized protein productivity 3-fold, whereas red light enhanced carotenoid content by 20.5-fold. The growth kinetics modeling that best matched the experimental data was the Gompertz modeling (R² > 0.649). These results demonstrate the wavelength-specific regulation of pigment and protein yields, suggesting that tailored light regimes can selectively optimize high-value metabolites in Navicula sp. This approach holds promise for biotechnology sectors prioritizing targeted compound production, such as nutraceuticals or biofuels, by leveraging spectral tuning to enhance metabolic efficiency and predicting particular growth phases using growth kinetics.

Abstract

Burr cells or also known as echinocytes are erythrocytes with short spicules evenly spaced and appear pale in the middle. Burr cells are found in patients with chronic kidney disease, burns, liver disease, uremia, microangiopathic hemolytic anemia, pyruvate kinase deficiency, post-transfusion, or can be found in the form of artifacts. This study aims to find the range of normal burr cell values in healthy adults and to find the correlation between burr cells with urea, creatinine, cholesterol, SGPT, and gender. The method used is a quantitative descriptive research design with a cross-sectional approach. Samples were taken using a purposive sampling technique, and 54 subjects who met the inclusion and exclusion criteria were analyzed for patient characteristics and laboratory results. The results showed a very weak relationship between burr cells with gender, creatinine, and SGPT with a correlation value of <0.1 and a weak relationship between burr cells with urea and cholesterol with a correlation value of >0.1 - <0.3. The normal burr cell value range was obtained with a lower limit value of 0 and an upper limit value of 30.88 burr cells per 1000 erythrocytes.

Abstract

Penelitian ini bertujuan untuk mengetahui dan mengungkap tentang eksistensi kesenian ronggeng dalam kesenian masyarakat di Ujung Gading Pasaman. Jenis penelitian ini adalah penelitian kualitatif dengan metode deskriftif analisis. Instrumen penelitian ini adalah peneliti sendiri dan dibantu dengan alat tulis, kamera dan alat perekam audio. Data dikumpulkan melalui studi pustaka, observasi, wawancara dan dokumentasi. Langkah-langkah menganalisis data adalah pengumpulan data, penyajian data dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa kesenian ronggeng masih hidup dan melekat kuat dalam budaya masyarakat Pasaman dan tradisi kesenian Ronggeng ini masih digunakan dalam kehidupan masyarakat, namun kesenian Ronggeng ini hanya diselengggarakan pada acara-acara tertentu seperti persta perkawinan, aqiqah, sunatan dan acara besar lainnya. Seiring berjalannya waktu, pelaku seni dari kesenian ronggeng tradisi ini banyak yang pergi merantau dan juga sudah banyak yang meninggal dunia, maka kesenian ronggeng Pasaman mengalami perubahan dan adaptasi dari waktu ke waktu, baik dalam hal alat musik, tempat, waktu, maupun penyanyi (parronggeng). Dikarenakan dalam jiwa pelaku seni yang ada di Pasaman masih melekat kesenian ronggeng ini, terciptalah pemikiran dari pelaku seni untuk menghadirkan kesenian ronggeng dalam bentuk alat yang berbeda, yaitu dengan menggunakan keyboard saja, dengan tetap menggunakan lagu atau pun pantun yang sama dengan ronggeng tradisi.
