Abstract

Tanaman buni (Antidesma bunius (L.) Spreng) memiliki khasiat obat dan digunakan secara tradisional. Selain itu, bagian daun tumbuhan diketahui memiliki potensi sebagai antimikroba terutama bakteri. Tantangan lain sebagai agen antimikroba adalah adanya fungi. Salah satu fungi yang banyak menyebabkan penyakit pada manusia adalah Candida albicans. Pengobatan infeksi C. albicans biasanya menggunakan bahan kimia antifungi yang dapat menimbulkan efek samping sehingga dibutuhkan alternatif pengobatan lain yang lebih aman. Tujuan penelitian ini adalah untuk mengetahui kemampuan ekstrak daun buni (Antidesma bunius (L.) Spreng) dalam menghambat pertumbuhan Candida albicans. Penelitian ini merupakan penelitian eksperimen dengan menggunakan dua pelarut ekstrak yaitu etanol 96% dan metanol. Konsentrasi ekstrak yang digunakan adalah 0,2:1; 0,4:1; 0,6:1; 0,8:1 gram/ml dengan kontrol negatif (DMSO 1%) dan kontrol positif (Ketokonazol dan Nystatin). Hasil penelitian menunjukkan bahwa daya hambat ekstrak etanol 96% dan metanol daun buni tidak terlalu berbeda. Penghambatan kedua ekstrak terbatas pada konsentrasi ekstrak 0,8:1 dan pada pengamatan jam ke-12 masa inkubasi penelitian. Efektivitas penghambatan ektrak daun buni tidak mencapai 50% dibandingkan dengan antibiotik Ketokonazol dan Nystatin 1000 ppm. Dari hasil ini diketahui bahwa ekstrak daun buni tersebut tidak efektif dalam menghambat pertumbuhan Candida albicans.

Abstract

Latar belakang dari pengembangan ini adalah rendahnya motivasi belajar dan literasi kesehatan reproduksi peserta didik akibat keterbatasan bahan ajar yang kontekstual, interaktif, dan relevan. Oleh karena itu, penelitian ini bertujuan untuk mengembangkan E-Modul Problem Based Learning (PBL) dengan pendekatan Socio-Scientific Issues (SSI) pada materi sistem reproduksi tentang HIV-AIDS untuk meningkatkan motivasi belajar dan literasi kesehatan reproduksi peserta didik kelas XI di Serui, Papua. Penelitian ini mengintegrasikan model PBL untuk mendorong pemecahan masalah berbasis kehidupan nyata serta pendekatan SSI untuk membangun kesadaran peserta didik terhadap isu sosial yang berkaitan dengan materi pembelajaran. Penelitian ini merupakan penelitian dan pengembangan (Research and Development) menggunakan model ADDIE (Analysis, Design, Development, Implementation, Evaluation). Subjek penelitian ini adalah peserta didik kelas XI MIPA 2 dan MIPA 6 di SMA Negeri 1 Serui tahun ajaran 2024/2025. Teknik pengumpulan data meliputi wawancara, angket, dan tes. Instrumen yang digunakan telah divalidasi oleh ahli materi, ahli media, dan praktisi (guru dan peserta didik), yang menunjukkan kategori “sangat valid” untuk aspek kelayakan isi, media, dan bahasa. Uji kepraktisan dilakukan dengan menyebarkan angket kepada guru dan peserta didik, sedangkan uji keefektifan dilakukan melalui pretest dan posttest menggunakan analisis MANOVA, setelah sebelumnya diuji normalitas, homogenitas, dan multikolinieritas. Hasil penelitian menunjukkan bahwa E-Modul PBL dengan SSI yang dikembangkan valid, praktis, dan efektif. Validitas media dan instrumen penelitian mencapai skor lebih dari 90% yang dikategorikan “sangat valid”. Kepraktisan menurut peserta didik dan guru juga sangat tinggi dengan skor di atas 90. Analisis MANOVA menunjukkan bahwa terdapat perbedaan signifikan antara kelas eksperimen dan kontrol dalam hal motivasi belajar dan literasi kesehatan reproduksi, yang mengindikasikan bahwa E-Modul efektif dalam meningkatkan kedua variabel tersebut. Berdasarkan hasil tersebut, disarankan agar guru biologi di wilayah dengan tantangan kontekstual seperti Papua memanfaatkan E-Modul ini sebagai bahan ajar tambahan yang relevan dan aplikatif dalam mendukung pembelajaran kontekstual dan meningkatkan kesadaran peserta didik terhadap isu- isu sosial yang aktual.

Abstract

This research aims to identify the diversity of lichen species in three different areas: Temon, Kulon Progo; Depok, Sleman; and Tegalrejo, Magelang. Besides that to analyze their ecological role as environmental bioindicators. The method used was direct field observation with visual documentation using a mobile phone camera, followed by morphological identification. The results of the study successfully identified nine lichen species: Flavoparmelia caperata, Physcia atrostriata, Dirinaria applanata, Phlyctis argena, Acarospora socialis, Ropalospora viridis, Pyxine sorediata, Cryptothecia striata, and Graphis sp.. These species exhibited unique adaptations to various substrates (tree bark, rocks, and urban environments) and showed sensitivity to environmental changes, particularly air pollution. The mutualistic symbiosis between fungi and photobionts (algae/cyanobacteria) is key to the resilience of lichens in marginal habitats. These findings strengthen the potential of lichens as natural bioindicators and ecological pioneers, while also highlighting the need for further research to map the distribution and applications of lichens in Indonesia.

Abstract

Abstrak Industri penyamakan kulit di Kawasan Industri Piyungan (KIP), Yogyakarta, menghasilkan limbah cair dengan kandungan kromium heksavalen [Cr(VI)] dalam jumlah signifikan yang bersifat toksik dan karsinogenik. Penelitian ini bertujuan untuk mengisolasi dan mengevaluasi bakteri endofit dari tumbuhan Pontederia crassipes (eceng gondok) sebagai agen bioremediasi Cr(VI). Sebanyak tujuh isolat diperoleh dari bagian akar, batang, dan daun, kemudian diseleksi berdasarkan kemampuan resistensi terhadap Cr(VI) melalui uji Minimum Inhibitory Concentration (MIC). Tiga isolat terpilih (PCr5, PCr6, dan PCr7) menunjukkan resistensi tertinggi hingga 2100 mg/L Cr dan bersifat non-patogen berdasarkan uji hemolisis, hipermukoviskositas, virulensi, dan gelatinase. Identifikasi molekuler menunjukkan bahwa ketiga isolat tergolong genus Pediococcus sp. Karakterisasi fisiologi dan biokimia menunjukkan isolat bersifat gram positif, kokus, non-motil, dan fakultatif anaerob. Profil pertumbuhan menunjukkan penurunan laju pertumbuhan pada media yang tersuplementasi Cr yang mengindikasikan efek toksik kromium. Uji bioreduksi menunjukkan bahwa ketiga isolat mampu mereduksi Cr(VI) dengan efektivitas tertinggi pada konsentrasi 50 mg/L, yaitu 54.29%–67.18%. Kata Kunci: Bakteri Endofit, Bioreduksi, Kromium Heksavalen, Pediococcus sp., Pontederia crassipes. AbstractThe leather tanning industry in the Piyungan Industrial Area (KIP), Yogyakarta, generates liquid waste containing significant amounts of hexavalent chromium [Cr(VI)], which is toxic and carcinogenic. This study aims to isolate and evaluate endophytic bacteria from Pontederia crassipes (water hyacinth) as potential agents for Cr(VI) bioremediation. A total of seven isolates were obtained from the plant’s roots, stems, and leaves, and were screened for Cr(VI) resistance using the Minimum Inhibitory Concentration (MIC) test. Three selected isolates (PCr5, PCr6, and PCr7) exhibited the highest resistance, tolerating up to 2100 mg/L of Cr, and were confirmed to be non-pathogenic based on hemolysis, hypermucoviscosity, virulence, and gelatinase tests. Molecular identification revealed that the three isolates belong to the genus Pediococcus. Physiological and biochemical characterization showed that the isolates are gram-positive, cocci-shaped, non-motile, and facultative anaerobes. Growth profile analysis indicated a reduced growth rate in Cr-supplemented media, suggesting a toxic effect of chromium. Bioreduction assays demonstrated that all three isolates were capable of reducing Cr(VI), with the highest reduction efficiency observed at a concentration of 50 mg/L, ranging from 54.29% to 67.18%. Keywords: Endophytic Bacteria, Bioreduction, Hexavalent Chromium, Pediococcus sp., Pontederia crassipes.
