Analisis Representasi Aspek Sustainable Development Goals (SDGs) pada Buku Teks IPA SMP di Kota Medan
This study aims to examine how the Sustainable Development Goals (SDGs) are presented in science textbooks used by seventh-grade junior high school students in Medan. The method employed was content analysis of two science textbooks published by the Ministry of Education and Yudhistira. The study focused on six SDG targets: Goals 2, 3, 6, 13, 14, and 15. The results show that the presentation of SDGs in the textbooks varies in clarity, quantity, quality, and context. Environmental aspects (SDGs 13, 14, and 15) appear more frequently than social and economic aspects (SDGs 2, 3, and 6), which tend to appear indirectly. Overall, the integration of SDGs in the textbooks does not fully reflect the principles of Education for Sustainable Development (ESD), as the content primarily emphasizes cognitive components rather than practical skills, attitudes, and actions. These findings highlight the importance of science textbooks in supporting sustainable education through curriculum updates, enhancement of ESD competencies, and the development of evaluation systems aligned with SDG achievement.

Morfologi dan Morfometri Pomacea canaliculata (Gastropoda: Ampullariidae) di Kecamatan Tulangan, Kabupaten Sidoarjo
This study aims to describe the presence of Pomacea canaliculata in Tulangan District, Sidoarjo Regency, and to identify its morphological and morphometric characteristics. The method used was purposive sampling, with specimens collected from three different locations: Saman Hudi River, Kepatihan Village rice fields, and Kenongo Village rice fields. Morphological observations included shell coiling direction, shell shape and color, aperture shape, umbilicus type, and operculum type. Morphometric measurements covered shell height and width, tentacle length, body whorl height, and aperture height and width. The results showed that Pomacea canaliculata shells are round, with yellowish-brown to dark brown coloration and spiral line patterns following the coiling direction. The aperture is oval to elongated crescent-shaped, slightly widened at the base, with a slit-type umbilicus, and a corneous operculum with concentric rings and a subcentral nucleus. Based on morphometric analysis using Principal Component Analysis (PCA), the largest Pomacea canaliculata individuals were found in Kepatihan Village rice fields, while the smallest were found in Saman Hudi River. Differences in morphology and morphometry among locations indicate significant environmental influences, including habitat conditions and natural selection.

Eksplorasi Potensi Actinomycetes Penghasil Antibiotik Baru dari Danau Poso Sulawesi Tengah Sebagai Antibakteri Patogen pada Manusia
This study aims to isolate, characterize, evaluate antibacterial activity, and identify Actinomycetes isolates at the molecular level. The method used was an experimental approach with a descriptive design. The research consisted of several stages: (1) isolation and characterization through macroscopic, microscopic, and biochemical tests, and (2) antibacterial activity testing and molecular identification of Actinomycetes isolates. The results showed that five isolates—DP1, DP2, DP3, DP4, and DP5—were identified and suspected to belong to the genus Streptomyces. Macroscopic and microscopic characterization indicated that all isolates exhibited white, yellow, and brown colony colors and were Gram-positive. Biochemical tests showed positive results for catalase, coagulase, oxidase, citrate, and TSIA tests. Antibacterial activity assays against Escherichia coli and S. aureusrevealed that isolate DP4 had the strongest inhibition zone, while showing negative activity against S. typhi. In conclusion, five Actinomycetes isolates were successfully isolated from the sediment soil of Lake Poso. Isolate DP4 demonstrated the greatest potential as an antibacterial candidate by inhibiting two pathogenic bacteria. Based on 16S rDNA sequence similarity analysis, isolate DP4 was identified as S. aurantiacus with 99% similarity. Keywords: Actinomycetes, Antibacterial, Lake Poso, Exploration
