Abstract

Indonesia is renowned for having some of the highest biodiversity levels in the world, which includes a wide variety of fern species (Pteridophyta). This study aims to identify and describe the fern species found in the Lemor Botanical Forest Area, East Lombok. The research used a descriptive-exploratory method with a cruise method approach, allowing direct observation and sampling in the field. The results showed a total of 9 fern families belonging to 20 species, with 50 individual plants recorded. The dominant family found was Pteridaceae, comprising 5 species. The species diversity was analyzed using the Shannon-Wiener diversity index, which yielded a value of 2.86, indicating a moderate level of species diversity. These findings demonstrate the ecological potential of the Lemor Botanical Forest Area in supporting the sustainability of fern species, and provide important baseline data for future biodiversity conservation and management efforts in tropical forest ecosystems.  In conclusion, in the Lemor Botanical Garden Forest area of East Lombok, 9 families of ferns have been identified.

Abstract

Profil Pelajar Pancasila (P5) merupakan upaya dalam mewujudkan perilaku siswa yang sesuai dengan nilai-nilai yang sejalan dengan pembelajaran paradigma baru. Salah satu sekolah yang menerapkan P5 ini ialah SMAN 1 Sekotong. Karena itu diperlukan pendampingan penyusunan kurikulum P5 yang bertujuan untuk membantu pendidik dan kepala satuan pendidikan dalam mengembangkan projek penguatan profil pelajar Pancasila. Kegiatan pendampingan penyusunan kurikulum ini dilakukan dilakukan melalui beberapa tahap kegiatan, diantaranya ialah (1) membentuk tim fasilitator P5, (2) identifikasi kesiapan sekolah dalam menjalankan P5, dan (3) menentukan dimensi dan tema P5. Pendampingan ini diawali dengan melakukan wawancara mendalam dan FGD pada tim fasilitator P5 yang ada di sekolah. Hasil wawancara tersebut dijadikan sebagai acuan dalam mengembangkan draft kurikulum P5. Hasil kegiatan pengabdian ini menunjukkan bahwa tema P5 SMAN 1 Sekotong terkait gaya hidup berkelanjutan ialah “Mangroveku Berkembang, Banjir Robku Berkurang”. Secara umum, kurikulum yang disusun terdiri dari (1) kegiatan yang harus dilakukan sebelum memulai projek, (2) tahapan dalam melaksanakan projek, (3) dimensi, elemen, dan sub elemen profil pelajar Pancasila, (4) aktivitas yang harus dilakukan oleh siswa, dan (5) refleksi dan assesmen formatif. Kurikulum P5 yang disepakati akan diterapkan padda tahun pelajaran 2024/2025.

Abstract

Dragonflies (Odonata) are bioindicators of environmental quality that are sensitive to changes in habitat conditions. This research aimed to analyze the dragonfly species found in the Kerandangan Nature Tourism Park, analyze their distribution patterns, and determine their diversity level. The research was conducted in three observation blocks, namely utilization, rehabilitation, and protection blocks. Sampling in this study was conducted using the line transect method with direct field observation. Distribution patterns were analyzed using the dispersion index, while diversity was measured using the Shannon–Wiener index (H’). The results showed that 18 dragonfly species belonging to 8 families were identified. The distribution patterns of dragonflies, both overall and within each block, tended to be clumped. The dragonfly diversity index (H’) in the Kerandangan Nature Tourism Park was 2.12, indicating that the ecosystem is relatively stable. In addition, damselflies (Zygoptera) were only found in the utilization block, which has water sources, and were absent in the rehabilitation and protection blocks. This finding suggests that abiotic and biotic environmental factors influence the presence and distribution of dragonflies in the study area. This research is expected to contribute scientific information to support enviromental management and conservation efforts in the Kerandangan Nature Tourism Park.

Abstract

This study aimed to determine the effect of red onion peel Liquid Organic Fertilizer, NPK fertilizer, and their interaction on the chlorophyll content and vegetative growth of Kangkung Darat. The research used a completely randomized design factorial with two factors: Liquid Organic Fertilizer dosage (0, 10, 20, 30 ml) and NPK dosage (0, 0.5, 1, 1.5 g). Four nitrogen rates (25%, 50%, 75%, and 100% of the recommended dose) and two phosphorus rates (50% and 100% of the recommended dose), each replicated three times, were used in the factorial Randomized Complete Block Design experiment, which was carried out in Rembige Village, Mataram City, between February and April of 2026. Analysis of variance and the Honestly Significant Difference test at the 5% significance level were used to evaluate the data. At 42 and 49 days following planting, nitrogen had a substantial impact on both the number of bulbs per clump and plant height. While the interplay between nitrogen and phosphorus had a substantial impact on leaf chlorophyll content, phosphorus had a considerable impact on bulb number, bulb diameter, and fresh bulb weight. This study concludes that the application of red onion peel Liquid Organic Fertilizer can complement or optimize the efficiency of NPK fertilizer, reducing environmental reliance on chemical inputs.
