ABSTRACT
Muryolobo Village, Nalumsari District, Jepara Regency, Central Java
Province, has great natural resource potential to supply the need for urug soil.
Mining activities carried out at the research site have stages including land clearing,
excavation of urug soil, loading and distribution, which have an impact on the
environment in the form of decreased land productivity, increased erosion, and the
potential for soil mass movement. This study aims to determine the land suitability
class of dryland agriculture land and the design of the reclamation plan based on the
evaluation of land suitability.
The methods used in the research include survey and mapping methods,
laboratory analysis methods, descriptive analysis methods, and weighing factor
matching methods. The parameters used refer to Hardjowigeno, 2020 namely
effective depth (s), grain size class (s), rocks on the soil surface (s), soil fertility (n),
topsoil reaction (a), slopes and other conditions soil surface (t), altitude (h), soil
erodibility (e), agro-climatic zone (c), drainage class (d), flooding and inundation
(f), and salinity (x).
The results of the evaluation of the land suitability of the research location
were divided into 6 classes of land suitability for dryland agriculture land, namely
N1sntd, N1snd, N2t, N2s, N2snatdx, and N1t. The mine reclamation directives
include (1) land arrangement with slope geometry engineering in the form of a bench
terrace with a slope of 450, a height of 4 m, and a terrace width of 8 m with a back
slope of 20-30 (2) construction of sewers (SPA) in each area. trapezoidal level (3)
planting soybeans with a spacing of 0.2 m x 0.4 m with a mound system, planting
cassava with a spacing of 0.7 m x 0.8 m with a mound system, planting sengon trees
with a spacing of 4 m x 4 m with a pot system, and planting vetiver grass with a
spacing of 2 m x 2 m with a pot system.
