Abstract

Selada (Lactuca sativa L.) merupakan sayuran bernilai ekonomi tinggi dengan permintaan yang terus meningkat. Namun, budidayanya di Indonesia masih menghadapi kendala, terutama dalam pemenuhan kebutuhan unsur hara dalam tanah. Penggunaan pupuk organik seperti guano serta pupuk anorganik seperti NPK dapat menjadi solusi untuk meningkatkan pertumbuhan dan hasil selada. Penelitian ini bertujuan untuk mengevaluasi pengaruh pemberian pupuk guano dan pupuk NPK terhadap pertumbuhan dan produksi tanaman selada. Penelitian menggunakan Rancangan Acak Lengkap (RAL) faktorial dengan dua faktor, yaitu pupuk guano (0, 1, 2, dan 3 gram) dan pupuk NPK (0, 0,75, dan 1,5 gram). Parameter yang diamati meliputi tinggi tanaman, jumlah helai daun, luas daun, berat basah, dan berat kering tanaman. Data dianalisis menggunakan ANOVA dua jalur dengan uji lanjut LSD dengan taraf kepercayaan 5%. Hasil penelitian menunjukkan bahwa pemberian pupuk NPK berpengaruh nyata terhadap tinggi tanaman, luas daun, dan berat kering, tetapi tidak berpengaruh nyata terhadap jumlah helai daun dan berat basah tanaman. Pemberian pupuk guano berpengaruh nyata terhadap semua parameter pertumbuhan dan produksi yang diamati. Kombinasi pupuk NPK dan guano juga memberikan pengaruh nyata terhadap seluruh parameter pertumbuhan dan hasil tanaman selada. Dengan demikian, penggunaan pupuk guano dan NPK dapat menjadi strategi yang efektif dalam meningkatkan produksi selada secara berkelanjutan

Abstract

This study aims to uncover and document the belief system (cosmos), local knowledge system (corpus), and the practice of plant utilization (praxis) in the traditional house of the Toba Batak Tribe. This research was carried out so that hereditary cultural knowledge about plants in the traditional house of the Toba Batak Tribe would not become extinct and would maintain its culture. This research was conducted in 2 villages in Sianjur Mula-Mula District, namely Sari Marrihit Village and Habeahan Naburahan Village. The research method is descriptive, qualitative, and quantitative. Data collection was carried out through semi-structured interview techniques, participatory observation, and documentation. The results of the study show that the Toba Batak Tribe believes that every plant used in traditional houses has a symbolic meaning, such as hope for sustenance, health, protection, harmony, unity, and sustainability of offspring. There are five species of plants from four families that are used and dominated by the Arecaceae family. The most widely used part of the plant is the trunk with the habitus of the tree. Plant processing is generally carried out by drying and the largest use is the interior elements of traditional houses. These findings show that the use of plants in the traditional house of the Toba Batak Tribe is not only functional, but also full of cultural values and local wisdom.
