This research is a new innovation to find alternative material to replace Portland cement filler by using sea sand. This study examined the effect of sea sand usage on Asphalt Concrete Binder Course (AC-BC) mixture with sea shifting variation of 25%; 50%; 75%, and 100%. This research is an experimental study in laboratory by using Marshall test method in the form of stability, melting, Marshall quotient (MQ), VMA, VFA, and VIM. To support the test results conducted in the laboratory research including physical examination of asphalt, aggregate, and filler. The results of this study obtained the value of Marshall characteristics for the best VMA is at 100% variation of 16.89%; The highest VFA value at 100% variation of 81,78%; The best VIM values are at normal conditions of 4.10%; The best density value in normal condition is 2.35 T/m³; The highest stability value under normal conditions of 1519.23 kg; The best flow rate is in the 25% variation of 4.52 mm; The highest MQ values are in normal condition of 453.21 kg/mm. The use of sea sand as filler in all variations can be used although not all Marshall characteristic variables are high in value compared with normal conditions without replacement. The more sea sand used as filler, the more asphalt content needed in a mixture, in this study the asphalt content increased 2% when compared with the condition without change

The Irrigation Area of Air Nipis is located in Regency of South Bengkulu at Bengkulu Province with irrigation area 3.116 Ha. Planning and management of irrigation systems is one of the important steps to determine the irrigation water requirement as a whole. The purpose of this research is aim to analyze the water requirement to get value prediction of minimum and maximum irrigation water requirement in irrigation area of Air Nipis using the CROPWAT Version 8.0 method. Irrigation water requirements obtained from CROPWAT Version 8.0 are based on climate data, soil data and plants.The parameters that were reference plant evapotranspiration, effective rainfall, soil treatment, soil data, and plants. The results of the research showed that the maximum irrigation requirement for calculation using CROPWAT 8.0 software occurred in the first 10 days of December (14,49 m3/sec), while the minimum irrigation water requirements for CROPWAT 8.0 occurs in mid to end March (0,04 m3/sec).

The order of mortar cement which used to bond individual units of masonry and to cover masonry wall keeps increasing. Meanwhile, the natural source of cement is limited. This article is the report of the research of the behaviour of mortar compression strength which used palm oil fibrous shell ash as the additive of cement. The ash used in this research was strained by strainer number 200. The ash discerned to the difference between the oven and unoven one. The proportions of cement and sand that used were 1:3 dan 1:5. The percentages of each of the ash were varied by the increment 2,5% between 0 to 10 %. 200 mortar 50 mm cubes distributed to each cell of samples were used according to ASTM C109/C109M-02. The concistency and the workability of the mortar was done by flow table test according to ASTM C-270. The mortar cubes were cured in water since the mall were gotten off. The compession test was held according to SNI 03-6825-2002 at 28 days of the cubes age. The results of analysis of variance (anova) of the mortar strength which used ovened ash were significant for the strength of the proportion 1:5 and unsignificant for the strength of 1:3 of the proportion. The strength of the significant one was inceased 0.66% at the mortar which used 10% ash. The results of the anova of the mortar strength with unovened ash were significant for the mortarproportion 1:3 and unsignificant for the strength of 1:5 mortar proportion. The strength of the significant one was 1,54% higher at mortar with 2,5% ash compared to the one without the ash.

Concrete building construction is easier and more economical when using local material including the water. This article is about improving swamp water by filtering it to use in concrete production. As the comparator is concrete with drinking water from The local water supply utility (PDAM) of Bengkulu. The 15 cm cubes specimens were tested at the age of 7, 14, 21, and 28 days to find out the compressive strength at different ages. The concrete was designed with water cement ratio 0.5, slump value 6-10 cm and maximum aggregate 20 mm. The casting and curing specimens were done according to SNI 03-2493-2002. The compressive strength results showed that the filtered swamp water concrete and the unfiltered one at 28th day were 98,2% dan 90,1% to the PDAM one. The trend of the compressive strength of swamp water concrete tend to decline with the increasing age. The compressive strength of swamp water concrete at age of 28th day was 89,1% lower than the strength at the age of 7th day. The filterred swamp water made the concrete compressive strength better.

The research aimed at investigating of the influence of surface roughing at semi-precast slab to slab strength on the first crack and the ultimate, the slab strength ratio made monolithically and composite, and to investigate crack and failure pattern of composite slab. The testing was conducted on two groups of slab which has 1:1 scales. Each group consists of three. The first group was monolith slab as control speciment. The second group was composite slab withsurface roughing. The test was conducted on two step. The first step, speciment was loaded by the repeated center static loading (10 cycle), the second step, the speciment was loaded from zero and increased step by step until speciment failed. Testing results showed that the first crack load of composite slab was approximately 14,2 % (width of 200 mm), 10,61 % (width of 400 mm), and 22,64 % (width of 600 mm) less than monolith slab. The ultimate (failure) load of composite slab was about 32,2 % (width of 200 mm), 9,8 % (width of 400 mm), and 15,9 % (width of 600 mm) less than monolith slab. The cracks occurred at slab speciment was vertical cracks extending through tensile side. The crack was indicated flexural crack, while the kind of failure type occurred at slab speciment was flexural failure.

Bengkulu city is one of the cities on the west coast of Sumatra island particularly vulnerable to earthquakes because it is located in an active seismic lines . This vulnerability allows the phenomenon of liquefaction when an earthquake occurs . One of the areas in Bengkulu city which through the lines is Lempuing Village . This study aims to analyze the liquefaction potential based on the data of Cone Penetration Test (CPT) using deterministic methods published by Idriss and Boulanger in 2008 . The data describes soil parameters, collected from the 6 point spread CPT test in Lempuing. Shear wave velocity data obtained from the correlation vs. the CPT data . Seismic load parameters used were obtained from the Indonesian Earthquake Hazard Map of 2010 and the seismic history of the city of Bengkulu. The magnitude of potential liquefaction happens to the value of Safety Factor (SF). The analysis at a depth of 0-2meter showed that most of the area in Lempuing with high potential of liquefaction, indicated by the value of SF is less than 1 . Furthermore , the results of the analysis are displayed in the form of Liquefaction Potential Map . This map shows that the entire area of Lempuing be in an unsafe condition to the danger of liquefaction during an earthquake with a magnitude > 7.9 earthquake and bedrock acceleration of 0.4 g.
