| dc.description.abstract | Tanaman aren (Arenga pinnata Merr) telah lama menjadi sumber pendapatan masyarakat setempat, dan dapat ditemukan tumbuh secara liar di Kabupaten Tapanuli Selatan. Tanaman ini tidak hanya menghasilkan nira yang diolah menjadi gula aren, tetapi juga ijuk, batang, dan daun yang berharga. Kondisi ini memungkinkan pembentukan sistem agroforestri alami yang berkelanjutan tanpa intervensi manusia yang signifikan. Dari sudut pandang ekologi, keberadaan tanaman aren membantu konservasi tanah, menjaga ketersediaan air, dan meningkatkan keanekaragaman hayati. Keberadaan tanaman aren dalam sistem agroforestri pada berbagai konidisi agroklimatologi, akan berdampak terhadap ekonomi dan mendukung kesejahteraan rumah tangga petani, sehingga prospek agroforestri berbasis tanaman aren di wilayah ini sangat besar. Hasil penelitian menunjukkan bahwa produksi nira terbaik ditemukan pada ketingian 500 – 800 m dpl, sedangkan kadar niranya pada ketinggian 0 – 400 m dpl. Sistem agroforestri terjadi secara alami, dimana tanaman aren tumbuh berdampingan dengan tanam lainnya sesuai dengan kondisi elevasi ketinggian tempat. Dari aspek ekologi, dengan sistem perakaran aren yang kuat mampu menahan tanah pada lahan miring sehingga menurunkan tingkat erosi dan mempertahankan kesuburan lahan. Dengan demikian, sistim agroforestri berbasis tanaman aren di daerah ini berpotensi besar untuk dikembangkan sebagai sistem pengelolaan lahan berkelanjutan yang mendukung ekologi dan ekonomi masyarakat. The aren palm (Arenga pinnata Merr) has long been a source of income for local communities and can be found growing wild in South Tapanuli Regency. This plant not only produces sap that is processed into palm sugar, but also valuable fibers, trunks, and leaves. These conditions enable the formation of a sustainable natural agroforestry system without significant human intervention. From an ecological perspective, the presence of aren plants helps conserve soil, maintain water availability, and increase biodiversity. The presence of aren plants in agroforestry systems in various agroclimatological conditions will have an impact on the economy and support the welfare of farming households, so the prospects for aren-based agroforestry in this region are enormous. The results of the study show that the best nira production is found at an altitude of 500-800 meters above sea level, while the nira content is found at an altitude of 0-400 meters above sea level. The agroforestry system occurs naturally, where aren plants grow alongside other plants according to the elevation of the location. From an ecological perspective, the strong root system of aren plants is able to hold the soil on sloping land, thereby reducing erosion and maintaining soil fertility. Thus, the aren-based agroforestry system in this area has great potential to be developed as a sustainable land management system that supports the ecology and economy of the community. | en_US |
