Design of concrete structures according to the applicable standard is to use the principle of the planning section of the load moment based on the principles of Bernoulli and Navier. Considered linear strain distribution and is considered still valid even though cross-section has been cracked and the planning sectionof the burden of a separate shear forces with the principle of Vc + Vs. The number of cases for the structural elements that have a fairly complicated shape will cause a problem in its design. This happens to the elements - structural elements such as high beam, corbel, beams with fairly abrupt changes in the dimensions, etc. This is evident from the occurrence of non-linear strain distribution so that it can no longer planned in a standard way. Planning is done sometimes only be approach with the regulations - regulations to existing standards, although sometimes there is a significant difference, one alternative approach to deal with is using Strut and Tie Model approach.

Bengkulu province lies on earthquake hazard zone where light and moderate earthquake often occur in relatively high frequency, due to geographical position of the province which is between 2 earthquake belts, Mentawai fault in Indian Ocean on Indo Australia tectonic plate and Sumatra fault around Bukit Barisan. Building failures due to earthquake mostly occur on residential structures. Although failures and damages due to earthquake generate major impact on residential structures, no lesson on the importance of mitigation by applying earthquake resistant structures on residential buildings is learned yet. Typical residential structures failures or damages that occur in Bengkulu city is mostly on engineered and non engineered brick wall. Since no available method of earthquake event prediction, hence mitigation is more important in order to prevent major loss and disaster any further. Hence socialization on earthquake and earthquake resistant structures/houses particularly on structural failure and damages that occurred in Bengkulu to the community is needed, also to transfer knowledge to the community about how to prepare residential buildings in earthquake hazard zones. By providing practical guidance about earthquake resistant residential buildings, socialization and technical training for construction workers, it is expected that the actions are able to assist the community to construct their residential buildings that comply to earthquake resistance standards and suits the particular needs of local residents, hence minimizing the effect of loss due to earthquake, usually defined as earthquake mitigation. Earthquake resistant residential buildings must comply standards of material and construction method.

Productivity is one of the important factors in determining the success of a construction job. Increased productivity will reduce work time, and that will reduce costs. In general, the value of productivity is determined by factors in the amount of work volume, time of implementation, and the number of workers. In order for the work to be completed properly, planning efforts are needed by taking into account these factors. For this reason, this study was conducted to determine the value of productivity in one of the components of building work, namely roof cover work. The objects studied were the work of installing roof coverings and the installation of 4 (four) project locations, namely the 4 x 25 Shophouse Construction Project in Meulaboh West Aceh, Building of the Rector & Administration Bureau of STKIP Building Nation Getsempena Banda Aceh, Construction of the Getsempena STIKes College Building Lhoksukon North Aceh and Construction of the East Aceh Bina Nusantara Idi STIKes Building. Roof material using zincalume material. The roof work volume is planned to be 2022.38 m2. The research was conducted through field observations by recording the work volume directly, the duration of each stage of work, and the number of workforce involved. The results of the analysis show that the productivity value for roofing work is obtained at 12,061 m2/hour or 96,487 m2/day and for roof joint installation work is obtained at 13,926 m / hour or 111,405 m/day.

The change of landuse at watershed (DAS) could influence that watershed’s condition. This affects runoff condition or changed of discharge of watershed. Lack of attention toward water resource management causes low support capacity of DAS such as lack of infiltration capacity or lack of water storage capacity. The understanding about process and how much effective rainfall happens including influencing factors are very needed as model to apply watermanagement and use system of field more effective. This research was conducted in five DAS of DI Yogyakarta and DAS in Central Java area. Those five DAS were DAS Code in Pogung, Code in Kaloran, Gajahwong in Papringan, Bogowonto in Pungangan and Progo in Badran. Effective rainfall method can be analysis by SCS-CN method. Effective rainfall obtained from these methods would be used for unit measurement of flood discharge design with unit hydrograph method.The result of research showed that The value of effective rainfall varied well from SCS-CN method. The design for flood discharge measurement with unit hydrograph method to compared with analysis frequency method. Initial abstraction is also very influential in the SCS-CN method.

Concrete is a material that have the strength to compression, but it is weak against tensile strength. The weakness of the tensile strength of concrete can be minimized by adding pandanus tectorius fiber. This study was aimed to determine the effect of adding pandanus tectorius fiber to split- tensile strength of concrete and percentage of the fiber in concrete that shows the highest split- tensile strength. The specimens used in this study is cylindrical with dimensions of 30 cm in height and 15 cm in diameter (SNI 03-4810-1998). Total of specimens is 32 that consist of 8 normal concretes and 24 variation concretes. An addition of pandanus tectorius fiber with the variation of 0,25%, 0,5%, and 0,75% was based on volume of the specimen. The mix design of concrete used water-cement ratio of 0.5 and slump of 60-100 mm. The splittensile strength of concrete was tested at 7 days and 14 days of dryng after immersing for 27 days. The result of split-tensile strength test of concrete with a variation of pandanus tectorius fiber showed a decreasing. The decreasing of split-tensile strength of concrete at 41 days was smaller than at 34 days to normal concrete. The highest decreasing percentage of split-tensile strength of variation concrete to normal concrete was respectively 9,249% (variation 0,25 tested at 41 days) and 14,518% (variation 0,75% tested at 34 days) .

Penelitian ini bertujuan mengetahui besarnya pengaruh penambahan abu sekam padi (ASP) terhadap sifat mekanis bata merah (kuat tekan dan absorpsi) dan persentase penambahan ASP yang terbaik untuk campuran bata merah. Metode penelitian yang digunakan berupa eksperimen dengan menambahkan ASP sebagai bahan campuran pembuatan bata merah. Variasi sampel bata merah yang dibuat yaitu bata normal (R0) dan bata merah dengan penambahan ASP (5%, 10%, 15%, 20% dan 25%). Jumlah sampel benda uji untuk masing-masing persentase penambahan ASP adalah sebanyak 20 buah bata merah. Berdasarkan penelitian yang dilakukan kuat tekan tertinggi terdapat pada sampel bata R0 (3,164 MPa), sedangkan kuat tekan terendah terdapat pada bata merah dengan persentase penambahan ASP 25% (1,030 MPa). Nilai absorpsi terbesar terdapat pada bata merah dengan penambahan ASP 25% (28,2%) dan yang terendah terdapat pada bata merah normal (23,1%). Berdasarkan hasil pengujian kuat tekan dan absorpsi bata merah dapat disimpulkan bahwa penambahan ASP dapat menurunkan nilai kuat tekan bata merah dan menaikan persentase absorpsi. Nilai kuat tekan berbanding terbalik dengan absorpsi bata merah.
