Abstract

Wisata alam Alas Karetan Desa Tempurejo seluas 5 Ha yang terletak di dalam kawasan lindung Sumber Pawon dengan luas 12,4516 Ha, mengalami ancaman dengan semakin meningkatnya kunjungan wisatawan dan konversi lahan. Kelompok masyarakat maupun aktivis lingkungan setempat mengharapkan adanya pengelolaan dan pengembangan wisata alam yang berbasis lingkungan dan berkelanjutan. Adanya permasalahan serta urgensi ancaman keberlanjutan di kawasan lindung Sumber Pawon mendasari dilaksanakannya kegiatan pengabdian masyarakat ini. Tahap awal adalah gambaran umum tumbuhan serta penentuan titik koordinat sebaran tumbuhan sebagai dasar pembuatan peta lokasi wisata, sebaran spasial tumbuhan lokasi dan intepretasi sebarannya. Pada tahap selanjutnya, media pembelajaran berupa e-booklet dikemas menarik dan mudah dipahami masyarakat. Potensi lokal kawasan Alas Karetan termasuk sumber mata air, keanekaragaman tumbuhan hutan tropis, tumbuhan langka dan berbagai macam satwa, perlu diketahui oleh masyarakat Alas Karetan. Dengan demikian tujuan program Desa Cerdas dalam kegiatan ini dapat tercapai yaitu pengembangan dan implementasi program maupun teknologi berupa media pembelajaran digital yang dapat meningkatkan potensi lokal daerah. Dalam pengaplikasian media pembelajaran peta dan e-booklet secara umum diperlukan pertimbangan yang matang, terkait kesiapan dalam pemantauan dan pengawasan lokasi sebaran tumbuhan lokal, terutama tumbuhan yang berpotensi sebagai tumbuhan ornamental. Dalam kegiatan abmas ini akan terus dilakukan komunikasi dan koordinasi secara berkelanjutan dengan pengelola wisata dan kepala desa, agar edukasi lingkungan bagi masyarakat ini dapat tercapai secara optimal.

Abstract

Polytyrene nanoplastics (NPs) (<1 µm) have high toxicity when entered and accumulated in cells. NPs accumulation causes oxidation stress, thus increasing reactive oxygen species (ROS) production, resulting in necrosis or apoptosis, as well as affecting endogenous antioxidant activity, such as superoxide dismutase (SOD) and catalase (CAT). Cinnamomum burmanni plant contains flavonoids, cinnamaldehyde, phen, and olic acid, potentially exogenous antioxidants. The study aims to analyze the potential of C. burmanni leaf extract for SOD and CAT levels, sperm quality, epithellia tubulus thickness, tubulus seminiferus diameter, and number of spermatogenic Rattus norvegicus cells exposed to NPs. Twenty-five male R. novergicus are divided into five groups (n = 5): two controls (without and with NPs) and three groups (combination of NPs and variations in extract concentrations of 100, 200, and 400 mg/kg. The SOD and CAT levels were measured with an ELISA kit. The histology was observed by counting the spermatogenic cells, measuring the epithellia thickness, and tubulus seminiferus diameter. The sperm motility, viability, and sperm count were observed to determine the sperm quality. Leaf extract of C. burmanni treatment with different concentrations not significantly increased SOD levels but significantly decreased the levels of CAT (P<0.05). The addition of C. burmanni leaf extract significantly increased the spermatogenic cell count, epithelia tubulous thickness, sperm viability, and sperm count (P<0.05), while sperm motility and tubulous seminiferous diameter not significantly increased. According to the results, C. burmanni leaf extract has antioxidant potential against the toxic effects of NPS.
