The purpose of this research is to analyze the potency of land water in the post tectonic earchquake at Merapi slope
in Klaten regency, Central Java. This research applies a survey method. The result of analysis is made based on the trilinier
diagram, Stiff pattern, and the quality standard of drinking water. The collected data are in the form of land form, shallow
land water data, suppressed land water, and well or spring. The results of the sesearch show that 1) the land form in Klaten
is divided into four sets of landform, they are peak and slope of volcano, feet of volcano, fluvial palin under volcano, and a set
of structural morphology. 2) the potency of land water can be tested based on the amount of land water and the quality of
land water. The amount of land water in Klaten regency 260,502,274 m3/year or 727,618,722 liter/day. The amount
of land water above is taken from free land water 73,301,436 m3/year, suppressed land water 34,138,520 m3/year, and
land water taken from well or spring 153,062,784 m3/year. The quality of shallow land water in Klaten regency is proper
to consume. 3) The distribution of upland water potency happens in the feet volcano land form, the potency of medium land
water happens in the superficial of fluvial under volcano land form, and the potency of lowland water happens in the slope
volcano land form and in the structural range of hills at Bayat subdistrict, 4) The tectonic earthquake gives serious effect toward
morphological changes, land split, land subsident and the potency of land water in the fluvial plain of land form under volcano
and structural range of hills in the area of Bayat subdistrict, and 5) In 2008, the needs of drinking water in Klaten regency
is predicted around 1,164,000 people x 150 liter/day = 174,600,000 liter/day.

Hydrologic modelling has been developing and it is usefull for basic data in managing water resources. The aim
of the reseach is to estimate volume runoff, maximum discharge, and soil erosion with SCS, Rational, and MUSLE
models on Keduang Watershed. Explain the data analysis, and flow to get the data. SCS parameters model use are :
runoff, rainfall, deferent between rainfall runoff. The deferent rainfall between runoff relationship kurva Runoff Coefisient
(Curve Nunmber/CN). This Coefisient connected with Soil Hydrology Group (antecedent moisture content/AMC),
landuse, and cultivation method. Rational parameters model use are : runoff coefisient, soil type, slope, land cover, rainfall
intensity, and watershed areas. MUSLE parameters model use are: rainfall erosifity (RM), soil erodibility (K), slope
length (L), slope (S), land cover (C), and soil conservation practice (P). The result shows that the conservation service
models be applied Keduang Watershed, Wonogiri is over estimed abaut 29.54 %, Rational model is over estimed abaut
49,96 %, and MUSLE model is over estimed abaut 48,47 %.

A study on degradations mangrove forest due to firewood exploitation by coconut palm sugar home industry
in Cilacap. Information on social economic aspect and respons of coconut palm sugar home industry to using fuel
substitutions were collected by using a questioner. The potential of mangrove as a firewood source was estimated by
quadrat method. The study has been carried out on dry and rainy season. The wood production of available 8000 ha
of mangrove from Cilacap primarily Rhizophora apiculata Linn and Rhizophora mucronata Lamk were 3.249.920
m3. The results showed that the declining of mangrove was about 19,250 m2 in dry season and 26,551 m2 in rainy
season, this was correlated with the amount of nira to be processed that was 0,782 m3 in dry season and 1,079 m3 in
rainy season. Deforestation of mangrove forest due to change of mangrove zonation. Rhizophora apiculata Linn and
Rhizophora mucronata Lamk will be domination Nypa fruticans, that is shown superficiality to continent form.

Physical conditions of seawater in coastal area can be studied by sampling at several locations. To perform
spatial analysis, the data should be interpolated to get the values between sample points. Several approaches for
interpolation may result in different outcomes. The purpose of this research is to compare Inverse Distance Weighted
(IDW) and Kriging methods. Their parameters are studied using the total suspended sediments in Maros area, South
Sulawesi. The results show that the more accurate interpolation is obtained by using IDW method than using Kriging
method
