Abstract

Kawasan Taman Mumbul merupakan daerah yang memiliki struktur vegetasi yang kerapatannya cukup tinggi, dan memiliki cukup banyak sumber mata-air. Adanya tegakan vegetasi pohon di suatu lahan memberikan peran penting menjaga stabilitas air tanah. Stabilitas air tanah ini akan menjadi sumber mata air yang memiliki banyak manfaat khususnya bagi masyarakat lokal. Oleh karena itu, penelitian ini bertujuan untuk mempelajari struktur vegetasi pohon di Kawasan Taman Mumbul dan melihat potensi wisata yang ada untuk meningkatkan perekonomian masyarakat lokal. Penelitian dilakukan di Kawasan Taman Mumbul, Desa Sangeh, Kecamatan Abiansemal, Kabupaten Badung, Provinsi Bali. Analisis vegetasi pohon dilakukan dengan Point of Center Quarter Method (PCQM). Dari hasil penelitian, diperoleh jumlah individu spesies terbanyak di area sebelah timur Pura Utama Taman Mumbul yakni Tectona grandis/Jati dan sebelah barat Pura Utama Taman Mumbul yakni, Theobroma cacao/Cokelat. Nilai INP tertinggi dimiliki oleh Tectona grandis/Jati sebesar 370,43% (timur) dan Cocos nucifera/Kelapa sebesar 150,46% (barat). Indeks Keanekaragaman (H’) di kedua area (timur dan barat) tergolong rendah. Indeks Kemerataan (e) di area timur tergolong rendah dan di area sebelah barat tergolong sedang. Keadaan tersebut menggambarkan pentingnya komposisi vegetasi yang baik agar dapat membantu menjaga ketersediaan air di dalam tanah. Keasrian dan stabilitas debit air menjadi potensi utama kawasan ini sebagai kawasan wisata lokal.

Abstract

The function of vegetation is to reduce rain erosivity and surface flow by intercepting rainwater that falls on it. The surface of the land covered by vegetation will help the occurrence of rain interception. Rain interception is the retention of rainwater on the surface of the vegetation before water enters the soil or evaporates back into the atmosphere. The Mumbul Park area has grass and bush vegetation that can help interception so that it can maintain the availability of water in the soil and supply water discharge for several springs. The research was conducted in the Taman Mumbul area, Sangeh Village, Abiansemal District, Badung Regency, Bali Province. To estimate surface flow, the Rain-Flow Model Application method is used. From the results of the study, obtained an average runoff in flat land for grass growthform as much as 4,202 cc and shrubs as much as 4,083 cc, on sloping land in a row of 5,473 cc and 6,423 cc, and on sloping land as much as 16,443 cc and 12,325 cc. The waiting time for runoff growthform on flat land and shrubs are 20s and 22s respectively, sloping land 19s and 14s, and sloping land 11s and 10s. Groundwater content during the rainy season is 42.9%; 41.3%; 40.0%. The Taman Mumbul area has several springs with large debits, but during the dry season there is a decrease in spring discharge by 15% to 50%. Even though there is no drought during the dry season in the Mumbul Park area, the decline in the number of springs discharge is a warning to maintain ecosystem stability, especially the hydrological cycle.
