BatangLampasi River was located in Talawi village, Nagari Koto Nan GadangPayakumbuh, about 30 km from Bukittinggi, with 48.19 km river length and around 226 km2 Cathment Area. The river flow carries a lot of sediment material, causing siltation on the riverbed which causes the river to overflow in the surrounding area. Sediment transport was triggered by Lampasi watershed erosion, that especially in the upstream section and settling on the riverbed. Prediction of depth decrease caused by sedimentation was conducted. Theoretical flood discharge determined used Nakayasu method. Sediment yield caused by land erosion determined by USLE equation and will compared with total sediment transport that calculated for 5 years return period with Yang's, Engelund Hansen, Ackers and White's methods. HEC-RASS 4.0 was used to find the high of flood water level and also as input hydraulics term to calculating transport sediment. The equivalent value approaching sediment yield was Yang's method where the sediment transport value is 21294,763 tons / year with sediment thickness of 27.24 cm / year. With these deposits thickness we can see from HEC-RASS 4.0 modeling the elevation of high flood water during normal conditions and the presence of thick sediment deposits.

Warping that occurs in fiber optik cables has the potential to cause serious power losses and further leads to optikal fiber rupture. Therefore, it is necessary to measure the effect of the optikal fiber curvature on the power loss generated when the optikal fiber is curved. This study aims to determine changes in the intensity of light output through plastic optikal fibers. this research distinguish the type of single mode cable and multi mode with varying radius. This paper only discusses the calculation of light output that has been affected by the curve of the optikal fiber. from the analysis conducted with a fiber optik cable length of 100 m, attenuation of 0.001 db / km and a bending radius that varies with a bend radius of 8 cm, 2x4 cm and 4 cm. different optikal fiber warping losses are obtained. that single mode cable is better than multimode cable.

Changing the land use of the Limau Manis area from the forest to the campus area can directly reduce water catchment areas, where water cannot soak into the ground, so that water reserves in the ground become reduced and run-off increases. To overcome this problem, an environmental friendly run-off control study was carried out, namely with recharge wells. The purpose of this study was (1) to find out the storage capacity of each infiltration well in the Padang State Polytechnic Campus, (2) to find out the number of infiltration wells to reduce run-off in the Padang State Polytechnic Campus, and (3) to know the effect of levels ground water to changes in infiltration rate. The method used in this study is land use analysis using QGIS. Analysis of rainfall using the Normal, Log Normal, Gumbel and Log Pearson Type III methods. Test the validity and suitability of the distribution with the Chi-Square and Smirnov-Kolmogorof tests. Run-off discharge analysis is calculated using the Rational method. Primary data were obtained by field testing and infiltration well making. The results of this study were (1) the capacity (volume) of storage in each infiltration well was different, where the largest infiltration well volume was 4.6 m3 while the smallest infiltration well volume was 3.1 m3, (2) the number of infiltration wells can reduce run-off varies, with 186 units of infiltration wells reducing by 34.2% runoff discharge to 65.8%, 113 infiltration well units reducing by 20.4% runoff discharge to 79.6%, 60 infiltration well units reducing by 10.8% runoff discharge to 89.2%, and 31 infiltration well units reduce by 5.5% runoff discharge to 94.5%, and (3) changes in groundwater content from 30.6% -50.6% cause a decrease in infiltration rate of 0.1 cm / minute.

Construction projects have a very high risk of work accidents. Work accidents will disrupt all project activities that can cause death and loss to the project. A work accident is an undesirable and unexpected incident which could result in loss of life and property. Based on Law No.1 of 1970 concerning work safety, work accident is an unexpected and undesirable event that disrupts the regulated process of an activity and can cause harm to both human victims and property. For this reason, it is necessary to have a construction safety management system using methods Hazard Identification Risk Determining Control (HIRADC). HIRADC will be implemented if there is support from management for occupational safety and health (OSH) in the form of policies, organizational structure and budget. From the studies conducted, the most common hazards are falling, punctured, scratched, tripped, bumped, inhaled dust, electric shock, exposed to concrete splashes with extreme risk of risk of injury, disability and even death. For this reason, there is a need for handling control in the form of mandating the use of PPE, administrative control such as making work instructions, SOP, must have SIO and SILO, installing signs, and doing engineering such as work methods, shopdrawing, providing regular training.

Electrical energy at this time is needed in daily life so that the demand for power from the community is so large. PLN in this case as a provider of electric current is very overwhelmed to meet customer demand. For this reason, alternative energy producers called renewable energy are sought, one of which is a micro hydro plant. In West Sumatra alone, PLTMH has considerable potential to reach 500 MW (Source: PLN West Sumatra Regional Research and Development), so that West Sumatra itself has been designated a green energy barn by the Ministry of Energy and Mineral Resources (Source: Ministry of Energy and Mineral Resources). This is a promising prospect to be developed so that PLTMH equipment can be made with the mastery of appropriate technology. Based on the survey that has been done generally making microhydro turbines is still doing manual work with simple production equipment and very low production volume. The delay in making this generator is in the runner which has a disk component as a holder where the blade will produce rotation. Part made has a specific contour shape and repetitive work. Making disk runners through six workmanship sequences using different CAD applications, tools and places. Jig and Fixture is a technological tool that is suitable for manufacturing micro hydro turbine disk runners where the material holder is on the dividing plate while the torch weld cutter is hung on the guide for the cutting process. These assistive tools designed can eliminate the work process. This mobile device can cut circles with a diameter of 200 mm-300 mm, a blade of as many as 28 pieces with the same distance, shape profile and accuracy and meet the ergonomic aspects for the operator.
