Padang Guci Hulu Subdistrict has potential to meet the needs of sizeable water supply. It is supported by geographical location of Padang Guci Hulu Subdistrict which is in the tropical region where there are hight enough rainfall. However in general the problem arising in Padang Guci Hulu Subdistrict during dry season is the availability of raw water and irrigation water that very limited. The purpose of this research is to design a strong and safe dam body construction againts its stability control. Planning dam body uses design flood from synthetic hydrograph gamma I with a return period 1000 years of 224,66 meter3/second. This dam isplanned as high as 31,3 meter, with dam base elevation of + 405 meter, peak elevation + 436,30 meter, high surveillance 2,8 meter, the width of the dam crest 8,5 meter, upstream sloop 1 : 3, downstream sloop 1 : 2,25. The body design of the Air Padang Guci Dam has qualified for its stability control.

This research purpose to know about people behavior in build permanent house,which see from house foundation reference on the concept of endure earthquake house. This observation have done with the way whice propagated quisioner amount 50 sheet to respondent (craftsman or own house) who building house. This way to find information about building the house. This research have done in North Bengkulu and Middle Bengkulu with took sample in six kecamatan are Air Besi, Arga Makmur, Karang Tinggi, Kerkap,Lais and Pondok Kelapa. This research produced information that making foundation to permanent house building still enough to fill. The concept of endure earthquake house. Because of that,we need a way from goverment in those region,acedemic and all of people to give information about how need build of house appropriate with the concept of endure earthquake house, because Bengkulu province is a earthquake area

Bengkulu is an earthquake prone area, so that the construction of buildings/houses should be based on the concepts of earthquake resistant houses. But to make earthquake-resistant housing, people has been frequently use material sea sand as a mixture of concrete. Research on the use of sea sandas fine aggregate in concrete mix is background by the availability of sea sand in a very large number in the city of Bengkulu. This study aims to find out how big the compressive strength of concrete is produced when using sea sand with some treatments. The treatment used to the sea sand is without treatment, soaked for 24 hours and the addition of lime 5%, 10%, 15% by weight ofcement. Concrete planned to use fas 0.5 with a cylindrical sample and amount 30 pieces. The results showed that the use of sea sand in concrete mix was a mixture of concrete without treatment produces an average compressive strength of 16.65 MPa, the concrete mix with soaked treatment of 19.79 MPa, and the addition of lime 5%, 10%, 15% in the amount of 20,72 MPa, 20,72 MPa,18,69 MPa

This research was made to find out the performance of primary canal and tapping constructions, also inquire the maintenance that should be done and prioritized in order to maintain the irrigation. Research method was conducted through direct observation to find out water discharge and primary canal dimensions and tapping constructions, also to inventory all of damage components. Secondary data was about dimensions and canal discharge plan,rainfall data, and climatology. Climatology and rainfall calculation is used to calculate quantity of irrigation water needed. Then, this irrigation water will be used to calculate water discharge during farming season. Hydraulic calculation of primary canal and tapping construction was based on those water discharge value. Results of the research showed water discharge and dimension of primary canal and tapping constructionsat Air Ngalam can irrigate whole rice fields. Unfortunately, canal rifts and damage, and some of illegal tapping by farmersaround cause water distributing on each rice field unequal. In order to optimize Air Ngalam irrigation, it’s a must to make a sequence of action plans in highest priority, also maintenance works.

Siltation due to sedimentation is one of the problems that occur in estuar of Ketahun River, Bengkulu Utara. The purpose of this study is to analyze the sedimentation particles and sediment discharge (bed load) at the mouth of Ketahun River. The location of this research is divided into three measurement points located on the downstream (facing the sea), the mouth of the river, and upstream (overlooking the river). The technique used to determine the sedimentation particle is by sieve analisis with various diameters (8,35 mm; 4,76 mm; 2,63 mm; 2,0 mm; 0,84 mm; 0,6 mm; 0,3 mm; 0,149 mm;, 0,074 mm). The percentage is calculated based on the weight of each sample with the results of sedimentation characteristic 0.3 mm smooth sand grains. To determine the basic sediment discharge (bet load) measurement is done directly in the mouth of the Ketahun River to get the river’s morphology and riverbed sediment samples. The samples were then examined in the laboratory, based on sieve analysis test to get the size of a grain diameter (D_35, D_50, D_60, D_90) and sediment specific gravity. The data obtained was then analyzed using empirical formulas-Peter Mayer and Einstein. From the analysis of sediment discharge at the river mouth to year basis obtained results: for method-Peter Mayer with Q_ukur = 2,596 x 10-6 m 3 / s and for the method of Einstein Q_ukur = 4,615 x 10-6 m 3 / sec. Results of the analysis shows that basic sediment discharge increases inline with the increasing river flow.

This research discusses the evaluation of the high waves, water level and redesign the dimension of jetty by replacing the protective layer of artificial stones made from concrete (quadripot). The data used in this study is from BMKG (Meteorology, Climatology and Geophysics Stasiun) Class 1 Pulau Baii Bengkulu which is the maximum wind data for the last 10 years (2005 - 2014) and tide data for the last 5 years (2007, 2008, 2009, 2012, and 2013). The primary data is the data of wave height conducted at the site for 14 days . The results of calculation from BMKG and data recording from the site, the highest wave break obtained is from the calculation from BMKG which is 3.34 meters and 8.13 second wave period. The results obtained from the analysis of jetty is HWL = 1.50 meters, MWL = 1.08 meters, LWL = 0.10 meters, DWL = 2.50 meters, peak elevation of the building = 5.1 meters , building height = 9,1 meter, protection layers of the head section weight = 1.2 tons, weight of the protection layers of the sleeve section 2.7 tons, thickness of protection layer of head section = 2 meters, thickness of protection layer of sleeve section = 2.5 meters, widht of protection layer of head section = 2.5 meters , width of protection layer of sleeve section = 3.5 m , the number of grains per unit area ( N ) in protection layer in head section = 17 grains per 10 m2 , and the number of grains per unit area ( N ) in protection layer in sleeve section = 10 grains per 10 m2 .
