Batukahu Nature Reserve

• During the reign of the Dutch East Indies Governor, the Batukahu Mountain Forest Group and its protected forest were designated as forest areas with a function of soil and water protection (hydro oro/ ogy reserve) with an area of ​​15,153.28 Ha, through the Decree of the Governor of Netherlands Indies Number 28 letter B sub.a .3 and b.1, dated May 29, 1927 and passed on 23 February 1934.
• On January 19, 1959, the Head of the First Level Region of Bali through Decree No. 19/53/2/4 set the Batukahu Mountain Forest Group to Nature Reserve as an insitu conservation area of ​​1,524 Ha and Eka Karya Botanical Gardens as an excess area of ​​45 Ha.
• On 29 November 1974, the Minister of Agriculture issued Decree of the Minister of Agriculture No. 716 / Kpts / Um / 11/1974 on the Designation of Batukahu Forest Area of ​​1,762.8 Ha Located in Tabanan District of Bali Province as Nature Reserve, named Batukahu I Nature Reserve, Batukahu II and Batukahu III.
• Based on the Limits Map of the Batukahu Nature Reserve which was certified by the Director General of Forestry on December 3, 1979, it was mentioned that the Batukahu Nature Reserve is a combination of three (3) nature reserve areas, which include 3 separate hill, namely Batukahu I Nature Reserve (Mount Tapak has an area of ​​810.40 Ha with an altitude of 1909 masl), Batukahu II Nature Reserve (Mt Pohang / Pohen has an area of ​​388.20 ha with a height of 2063 masl ), and Batukahu III Nature Reserve (Mt Lesung with an area of ​​564.20 Ha and a height of 1865 masl).

The topography of this region varies, hilly and bumpy from flat, sloping, sloping, steep, steep, and steep to very steep. This Nature Reserve consists of three separate hill locations, namely Batukahu I Nature Reserve (Bulit Tapak), Batukahu II Nature Reserve (Pohang / Pohen Hill), and Batukahu III Nature Reserve ( Lesong Hill).

Based on the Spatial Plan of Tabanan Regency in 2012 and the 2012 Buleleng Design Plan, Batukahu Nature Reserve has a volcanic rock formation from the cone of Sub Puchenen Mountain, Mt Sengayang, and Mt Lesung.

Batukahu Nature Reserve generally consists of andesitic rock, basalt, tephra smooth / rough and recent volcanic due to activities from the results of ancient volcanic eruptions of Batukahu, Lesung and Pawon at the middle of the quarter.

Based on the stratigraphic structure, the sequence of occurrence is preceded by volcanic deposits of Buyan-Beratan volcano and ancient Batur (Qba). The top layer is the result of the ancient volcanic sediment (Qbb), namely tuff and sediment Buyan-Beratan and ancient Batur. The youngest layer consists of Qve from the results of volcanic activity and the result of the sediment. Lithology of the region consists of breccia, andesite deposits, lr and luff deposits, which are spread over Qba formations, lava sediment generally dominates the Baral and Southern parts. The southern and eastern parts are dominated by lava deposits of Qbb formations, whereas the alluvium (Qal) region generally consists of a mixture of fine lava to boulder.

The condition of the land in the Batukahu Nature Reserve area can be described as follows:

PH land in Batukahu Nature Reserve ranges from 5.1 to 5.7 with soil moisture ranging from 47-59%. This is due to the moist mountains and highlands that cause high rainfall resulting in the release of soluble salt base compounds containing Ca, Mg, and K ions as the source of OH ions. Because of the release of these compounds so that there is a reduction in the number of bases that cause the moist soil and located in the highlands become more acidic. The moist soil is dominated by silicic clay and humus which is much acidic because of the outer surface of silicate clay there are many sources of H ions ie AlOH and SiOH and carboxyl and phenol groups in colloid humus.
