Abstract

Sugarcane has been widely used to treat various diseases due to its metabolite content. Tissue culture is one method that can be used to produce metabolites and is an alternative biotechnology as a conservation strategy. This study aims to analyze the differences in metabolite content in sugarcane plantlets cultured with different media and subculture frequencies. Plantlets were extracted using the maceration method with 70% p.a. ethanol solvent. Metabolite analysis was carried out using a Gas Chromatography-Mass Spectrometry (GC-MS) instrument. Metabolite identification was carried out based on the NIST library. The results showed that the 10th subculture of sugarcane plantlets cultured on MS+Kinetin+Coconut Water media contained 5 metabolites, while the 11th subculture of plantlets cultured on MS+Kinetin+Tidiazuron media contained 7 metabolites. Differences in the type and number of metabolites indicate the influence of culture conditions on the metabolite profile of the plantlets. This study provides an initial overview of the potential of sugarcane tissue culture in the production of secondary metabolites.

Abstract

Abstrak. Ketergantungan manusia terhadap lahan sangat terlihat nyata dengan adanya perubahan fungsi lahan. Perubahan fungsi lahan juga berdampak terhadap tingkat biodiversitas tumbuhan. Studi ini mempelajari tingkat biodiversitas dan kelimpahan tumbuhan di tiga lokasi yang berbeda yaitu lahan konservasi pinus/perkebunan kopi, lahan persawahan dan lahan pemukiman. Ketiga lahan tersebut berada di Daerah Aliran Sungai (DAS) Cilaja yaitu di Desa Giri Mekar dan Desa Sindanglaya Kabupaten Bandung. Dalam penelitian ini dilakukan metode sampling struktur komunitas vegetasi untuk mengetahui komposisi, struktur dan jenis vegetasi serta perbedaan komunitas di tiga titik lokasi tersebut. Untuk analisis kuantitatif digunakan metode kuadran. Hasil penelitian menunjukkan bahwa lahan pemukiman desa lebih beragam dibandingkan dengan lahan sawah dan lahan perkebunan kopi. Dapat disimpulkan secara umum bahwa keterlibatan dalam mengelola lahan dapat merubah komunitas, tingkat keanekaragaman dan dominansi tumbuhan.Kata kunci : DAS, tingkat biodiversitas, metode sampling struktur komunitas vegetasi Abstract. Human dependence on land is very evident with the change in land use. Changes in land use also have an impact on the level of plant biodiversity. The study followed the level of biodiversity and abundance of plants in three different locations namely conservation land pine / coffee plantations, rice fields and residential land. The third land is located in the Watershed (DAS) Cilaja is in the village of Giri Mekar and Rural Sindanglaya Bandung regency. In this research, community structure vegetation sampling methods to determine the composition, structure and type of vegetation and the three-point difference in the communities that location. For quantitative analysis used kuadran method. The results showed that the rural residential land is more diverse than the wetland and coffee plantation. In general it can be concluded that involvement in land management can change the community, the level of diversity and dominance of plants.Keywords : DAS, level of biodiversity, community structure vegetation sampling methods

Abstract

Sekolah memiliki peran penting dalam mengubah perilaku siswa, terutama melalui integrasi materi kebencanaan dalam kurikulum IPA. Calon guru IPA berperan dalam membentuk karakter peduli lingkungan. Peningkatan literasi lingkungan berkontribusi pada perubahan perilaku proekologis dan mendukung pembangunan lingkungan berkelanjutan. Kajian ini mengacu pada kurikulum Program Studi Pendidikan IPA dengan tujuan mendeskripsikan profil kebutuhan perkuliahan terkait mitigasi bencana untuk pengembangan program lebih lanjut. Penelitian ini menggunakan metode field study dengan tiga pendekatan utama: pengumpulan data melalui dokumen, interaksi dengan narasumber, dan observasi di lokasi penelitian di Program Studi Pendidikan IPA jenjang S1 dan S2. Teknik pengumpulan data yang digunakan adalah instrumen non-tes, melibatkan analisis dokumen kurikulum, RPS mata kuliah Mitigasi Bencana, dan angket literasi lingkungan. Hasil analisis kurikulum dan RPS menunjukkan evaluasi yang baik pada identitas program studi, visi, misi, tujuan, dan strategi kurikulum. Meskipun tracer study alumni masih perlu ditingkatkan, keterkaitan antara capaian pembelajaran dengan kompetensi lulusan serta interaksi antara mahasiswa dan dosen dinilai baik. Wawancara dengan dosen mengungkapkan bahwa tujuan perkuliahan mitigasi bencana adalah menciptakan kesadaran akan bencana, dengan fokus pada prekursor kebencanaan dan kebiasaan masyarakat saat bencana terjadi. Integrasi kearifan lokal dalam menghadapi bencana masih terbatas, dan buku ajar atau modul yang menggabungkan kebencanaan dengan kearifan lokal masih kurang. Literasi lingkungan mencakup aspek sikap, kesadaran akan kelestarian lingkungan, dan perencanaan tindakan terhadap lingkungan, semuanya menunjukkan hasil yang baik dengan persentase di atas 60%.

Abstract

Situ Bagendit merupakan danau alami yang saat ini mengalami penurunan kualitas lingkungan akibat pencemaran serta perilaku masyarakat yang tidak ramah terhadap lingkungan. Penelitian ini bertujuan untuk mengkaji tingkat kepedulian lingkungan masyarakat dan menilai relevansi antara kepedulian lingkungan dengan tindakan nyata dalam upaya menjaga keberlanjutan danau Situ Bagendit. Penelitian ini menggunakan metode deskriptif kualitatif dengan teknik purposive sampling terhadap 100 responden dari lima kelompok masyarakat di sekitar Situ Bagendit, Kabupaten Garut, Jawa Barat. Data dikumpulkan melalui observasi, wawancara, dan kuesioner yang mencakup aspek pengetahuan, sikap, serta penerapan prinsip-prinsip etika lingkungan. Hasil penelitian menunjukkan bahwa masyarakat memiliki tingkat kepedulian lingkungan yang tinggi berdasarkan penerapan prinsip etika lingkungan, dengan prinsip kasih sayang dan peduli terhadap alam mencapai 83,6% sedangkan prinsip lainnya menunjukkan nilai di atas 75%. Meskipun demikian, kondisi aktual Situ Bagendit masih menunjukkan permasalahan lingkungan yang serius dengan ditemukannya sampah dan pertumbuhan gulma air secara masif. Temuan ini mengindikasikan adanya kesenjangan antara tingkat kepedulian yang tinggi dengan perilaku nyata masyarakat dalam menjaga lingkungan. Oleh karena itu, relevansi antara kepedulian dan perilaku masyarakat belum sepenuhnya terwujud dalam praktik kehidupan sehari-hari, sehingga diperlukan strategi pendidikan lingkungan dan penguatan regulasi untuk memastikan nilai-nilai etika lingkungan tercermin dalam perilaku nyata masyarakat.

Background: This study aims to analyze the feasibility of honeybee cultivation attractions as an object for developing educational ecotourism and to formulate strategies for developing the “Honey Picking” educational tourism package at Ir. H. Djuanda Grand Forest Park (Tahura), Bandung. Methods: This research employed a descriptive method with a qualitative approach. Primary data were obtained through observation, in-depth interviews, and questionnaires distributed to visitors using purposive sampling, while secondary data were gathered from literature reviews and relevant supporting documents. Data analysis was carried out using the SWOT method to identify internal and external factors influencing the development of the tourism package. Findings: The results show that the honey-picking educational ecotourism program has strong internal strengths and favorable external conditions, with IFAS and EFAS scores of 3.03 and 2.89, placing it in Quadrant I. Interactive educational activities, natural attractions, accessibility, and community support drive growth, while improvements in digital promotion, management capacity, and safety standards are required to ensure sustainable development. Conclusion: The study concludes that the “Honey Picking” educational ecotourism package holds strong potential to be developed as a sustainable conservation-based educational tourism model. This activity not only increases visitors’ knowledge and environmental awareness but also provides economic and social benefits for local communities and supports biodiversity conservation efforts in the Ir. H. Djuanda Grand Forest Park area, Bandung. Novelty/Originality of this article: The novelty of this study lies in its development of an interactive “Honey Picking” edu-ecotourism concept based on honeybee cultivation, which has not previously been explored in the context of Tahura Ir. H. Djuanda. Additionally, the study offers a strategic, data-driven framework using SWOT analysis to guide the creation of sustainable conservation-based educational tourism packages.

Abstract

Leukemia is caused by abnormal white blood cell proliferation that leads to disruption of conventional blood cell functions. Mangosteen (Garcinia mangostana L.) contains phytochemical compounds with strong anticancer properties, according to various cancer studies. This study investigated the potential of mangosteen peel extract (MPE) as an anti-leukemia agent through molecular docking of LC-MS-identified compounds against FLT-1 and AKT proteins, followed by in vitro evaluation on HL-60 cells, namely cytotoxic (WST-8 assay), ROS levels and senescence (flow cytometry), and then FLT1 and AKT gene expression (qRT-PCR). LC-MS identified α-mangostin, β-mangostin, γ-mangostin, mangostinone, and epicatechin as the main compounds. Molecular docking revealed strong binding affinities from −8.5 to −9.9 kcal/mol against AKT, and from −9.0 to −9.9 kcal/mol against FLT-1. MPE (500 µg/mL) decreased cell viability and increased inhibition of HL-60 cells. Intracellular ROS levels decreased significantly at 0.6, 1.2, and 2.4 µg/mL MPE. MPE induced cell senescence especially at 1.2 and 2.4 µg/mL. Gene expression analysis revealed downregulation of AKT at 1.2 and 2.4 µg/mL and FLT1 at 2.4 µg/mL. These findings suggest that MPE may exert multifactorial anti-leukemic mechanisms, including apoptosis, ROS modulation, senescence induction, and regulation of AKT and FLT1 expression.
