Abstract

Microbiological contamination is one of the factors that affect food safety, especially in wet noodles which have a high moisture content so they are easily damaged. This study aims to determine the number of Total Plate Numbers (ALT) and identify the presence of Escherichia coli in wet noodles sold at Segiri Market, Samarinda City. The research was carried out using a descriptive analytical method through laboratory testing of five wet noodle samples taken by purposive sampling. ALT testing uses the pour plate method on Plate Count Agar (PCA) media, while Escherichia coli testing is carried out by the Most Probable Number (MPN) method followed by confirmation on Eosin Methylene Blue Agar (EMBA) media. The results of the ALT test showed that two samples met the maximum limit of ALT according to SNI 2987:2015 (≤1.0 × 106 colonies/g), while three samples exceeded the threshold. The MPN test showed that four samples were below the maximum limit according to SNI 2987:2015 (≤10 APM/g) and one sample exceeded the threshold. The EMBA confirmation showed two positive samples of Escherichia coli. These results confirm the importance of applying hygienic practices in the processing, storage, and packaging to reduce the risk of microbiological contamination.

Abstract

The effect of light on stomata has been extensively studied, but studies that specifically observed the effect of light intensity on the size and number of stomata in monocot plants at the Sempaja Arboretum, Samarinda, are still very limited, including monocot plants, and have the potential to be a contextual learning resource for biology education in schools. The purpose of this study is to determine the effect of light intensity on the number and size of stomata in monocot plants in the Sempaja Arboretum. This research was carried out from February to May. This study used a Non-Factorial Group Random Design, with 3 different light intensities (morning, noon, and evening). Based on the results of statistical tests (ANOVA and Duncan's follow-up tests), not all species show statistically significant differences in size and number between times (morning, noon, evening). Some species such as Sri Rejeki (Aglonema sp) and Turmeric (Curcuma longa) show statistically insignificant changes. In other species such as Virginia Flower (Commelina virginica), Palm (Arenga pinnata), and Golden Ivory Betel (Epipremnum aureum), the difference in stomata size between times is more pronounced and significant.

Abstract

The background of this research is learning models that are limited in variation, which makes the students less active, especially in questioning skills. Because of that, this research has a purpose to find out the effect of implementing the Problem Based Learning (PBL) model based on Technological Pedagogical and Content Knowledge (TPACK) on students questioning skills. This research used a quantitative approach with a quasi experimental method and a non- equivalent control group design. The subjects of this research are 70 grade XI students in MAN 2 Samarinda, including class XI-B as the experimental class and class XI-A as the control class. The instruments used in this research are interviewing the teacher, observing the learning activities, and an assessment rubric of students questioning skills. The results of this research showed that students questioning skills in the experimental class increased significantly compared to the control class, as shown by the Mann-Whitney U test with a significance value of 0.015 < 0.05. The number of questions from students in the experimental class was more varied (20 questions) compared to the control class, which had fewer questions (5 questions). The conclusion is that the implementation of the TPACK based Problem Based Learning (PBL) model has a positive effect on students questioning skills in the cell material of Grade XI.

Abstract

Pencemaran mikroplastik telah menjadi isu global yang serius karena dampaknya terhadap ekosistem perairan dan kesehatan manusia. Penelitian ini bertujuan untuk menganalisis jenis dan kandungan mikroplastik pada ikan Trakulu (Lepidothyris fernandi) dan ikan Kerapu (Epinephelus sp) yang ditangkap di perairan Muara Ilu, Kecamatan Anggana, Kabupaten Kutai Kartanegara, Kalimantan Timur. Penelitian ini menggunakan pendekatan kualitatif dengan metode deskriptif analitis. Sampel diperoleh melalui pemancingan, lalu bagian saluran pencernaan ikan dianalisis menggunakan larutan KOH 10% dan diamati melalui mikroskop cahaya yang terhubung dengan Optilab dan aplikasi Image Raster. Hasil penelitian menunjukkan bahwa ikan Trakulu mengandung tiga jenis mikroplastik yaitu fiber, film, dan fragmen, dengan dominasi fiber sebesar 76,92%. Sementara itu, ikan Kerapu mengandung dua jenis mikroplastik, yaitu fiber dan film, dengan dominasi fiber mencapai 95,08%. Temuan ini menunjukkan bahwa perairan Muara Ilu telah tercemar mikroplastik dan ikan konsumsi lokal berpotensi menjadi vektor masuknya partikel tersebut ke dalam rantai makanan manusia. Penelitian ini diharapkan menjadi dasar dalam pengelolaan lingkungan dan peningkatan kesadaran masyarakat terhadap bahaya pencemaran plastik.

Abstract

Benanga Reservoir in Samarinda serves as a water source, river conservation area, and fishery location that supports local subsistence and commercial activities. However, the suboptimal management of plastic waste around Benanga Reservoir increases the risk of microplastic pollution that threatens human health and food security through fish consumption. This study aims to identify the types and amounts of microplastic contamination in Tilapia (Oreochromis niloticus) and Puyau (Osteochilus vittatus) in Benanga Reservoir waters. The research method is quantitative-descriptive exploratory. Fish samples were taken by purposive sampling method at 4 station points using a net (gillnet), the gills and digestive tract were destroyed using 10% KOH and flotation with 0.9% NaCl to be observed using a light microscope with the help of optilab viewer. Data were analyzed using descriptive statistics. Analysis of 12 fish samples showed the presence of microplastic contamination in all samples with a total of 155 particles including fiber, film, fragment, and pellet forms with various colors and sizes. The average abundance of tilapia is 11.4 particles/tail, while in puyau fish it reaches 14 particles/tail. Cumulatively, the level of microplastic contamination in puyau fish (98 particles) was identified as higher than in tilapia (57 particles), with fiber particles predominating in both species. The presence of microplastics in this local fish population emphasizes the urgency of waste management and pollution mitigation to ensure food security and ecosystem integrity in the Benanga Reservoir.

Abstract

This study aims to determine the effect of Genially interactive media supported by the discovery learning model on students' cognitive learning outcomes in the nervous system. This research is motivated by the low level of student active engagement in learning, necessitating innovative media and learning models that support meaningful conceptual understanding. This study used a quasi-experimental method. The subjects consisted of an experimental class using Genially media supported by the discovery learning model and a control class using the expository model. The study was conducted on eleventh-grade students of SMA Negeri 5 Samarinda on the nervous system. The research instrument was an essay test administered before and after the lesson. Data analysis included normality tests, homogeneity tests, hypothesis testing using the independent sample t-test, and N-gain calculations. The analysis results showed that the data were normally distributed and homogeneous. The hypothesis test revealed a significant difference between cognitive learning outcomes in the experimental and control classes. The improvement in cognitive learning outcomes in the experimental class was in the moderate category and higher than in the control class. Thus, Genially interactive media supported by the discovery learning model is effective in improving students' cognitive learning outcomes in the nervous system.
