Abstract

Upper Citarik Catchment has an area of about 30,41 Km2 or around 30.000 Ha. Based on topographic map “Rupa Bumi Indonesia”(RBI), the upper area of the catchments still covered by forests which can restrain the increase of runoff coefficient.There is also water fall “Curug Cinulang in the Catchment, the interesting natural tourist attractions that push the growth of economic activities and tourism facilities, changing land use which can increase runoff coefficient and improve flow discarge. The research method used was land use mapping based on the Topographic Map “RBI” with scale of 1 to 25000, and measurements of each land use types using GIS techniques. Discharge estimation using empirical formula and measurements in the field. The results showed dense forest cover, plantations, and scrub affect the coefficient runoff. Forests affect the stability of the river flow based on measurements and calculations with different assumptions rainfall intensity. The river discharge was relatively stable at stations 6 and 7 with more than 90% of land covered by good forest.

Abstract

Jakarta, a very populated capital city of Indonesia, was built above alluvial deposit which is currently subsiding relative to sea level at a high rate. As a result Jakarta becomes more often to be flooded with water that delivered from other regions and also the sea level rises relative to land and shoreline move toward the ground are increasing feasibility of tidal flood to occur. Consolidation process of the ground acts as a cause to the land subsidence in Jakarta. The fact is water needs in Jakarta is high due to its high population. Therefore, large amount in withdrawal of groundwater occurs and causes the ground to settle. In order to decrease the rate of land subsidence, groundwater should be extracted in a proper, more effective and efficient way. Younger generation is advised to save water using a fresh approach which is easy to be understood and accepted. In the future, people in Jakarta will consider that saving water as a norm which brings great benefit to their environment, Jakarta.

Abstract

Research location at Rector Building area, Unpad Campus, Jatinangor. The study is a part of research of Jatinangor engineering geology. Strength prediction of soil bearing capacity for shallow foundation is performed by measuring the water content of the soil at four locations sampled. Based on the formula of Hirnawan & Zakaria (1991), a variable value of unit weight (γ)  = 1.73 T/M3; cohesion (c ) = 7.80 T/M2; and angle of friction= 13.69 degrees. The soil variables based on the value of water content by 43.85%. The result of soil bearing capacity (in dry conditions) around the ground surface of the rector building area is as follows: Type of foundations Square = 17,732 T/M2; Circular foundation type = 17,708 T/M2; Continuous foundation type = 13.714 T/M2. In wet conditions, the value of carrying capacity must be calculated again.

Abstract

Foraminifera live from shallow marine into deep marine. Environment itself has their own characteristic of foraminifera. Indonesia which is an archipelago country has highly foraminifer’s diversity. Research area is located in Jepara Water and is a part of Java Sea. Geographically, core-01 is lied on 05055’18.66” Latitudes and 110042’34.55” Longitudes. This research is done in order to know the diversity of recent small benthic foraminifera , so that, is there an environmental changes of core-01. Quantitative method is used on 12 sample sediment below sea floor with interval depth 50.00 – 50.55 meter. The identified recent small benthonic foraminifera are compound of 43 genera and 73 species. Based on research, there are changes of diversity genera, diversity species, and individual numbers of recent small benthic foraminifera. Those changes can be used as an indicator of vertically core-01 environmental changes.

Abstract

Carbonate rock is one of reservoir rock types in petroleum. It is interesting to study because its special characteristic, that is, it can change so easily that will affect to quality and quantity of reservoir. This research has been done at Kemang Baru area and around, Sijunjung Distric. Purposes of this research are to know texture and composition characteristic and to know what kind of environment deposition and diagenesis process involved as long as the formation. To get the information about that, petrography and Palinology methods are used. The result of this research shows that only 37 samples of carbonate type from 69 samples which have been analized. These are wackestone and mudstone. They have been formed at low energy environment and in reduction process which is characterized by present of pyrite in the rocks. To support the data, result of Palinology analysis, the rock have contained Dicolpopollis sp., Margocolporites sp., Palmaepollenites sp. and Psilatricolpites sp, berasosiasi dengan Acrostichum sp., Detloidospora sp., Hyphae sp., Inaperturisporites sp., Laevigatosporites sp., Verrucatosporites sp. Based on these, the rocks were formed at deep Lake.

Abstract

Twenty sea surface sediment samples are taken for research. Research area is located at Semarang Water and lied on 109º38’08,53’’ - 109º 43’31,57’’ BT and 05º 30’00’’ - 06º28’46,02’’ LS. Benthic foraminifera is marine unicellular animal that very useful to determine environment. The purpose of this research is to determine the genus of dominant small benthic foraminifera in order to interpret the environment. Based on quantitative method, result of the research shows total of genera is 29 with 145335 individual. Six genera which occur in all over samples are Ammonia, Anomalina, Asterorotalia, Elphidium, Heterolepa and Quinqueloculina. Genus Heterolepa is small benthic foraminifera dominant with total percentage individual is 35.957%. Based on the dominant genus, the environment of research area is marine (neritic).
