Abstract. Open channel conduit is commonly constructed on side roadway, car park area, etc., with the aims to collect rainwater or seapage water. To avoid garbages following the waterflow, the conduit is equipped with adequate cover. In addition, the cover can also be functioned for temporary car park area. Thus, the conduit cover should strong enough to sustain external loading. This paper discusses the design and response of the conduit cover using finite element software ANSYS MECHANICAL version 17.5.

A prototype of rail turnout motor measurement device was designed based on motor torque inspection, using a load cell sensor. A rail turnout is a branched railroad construction to control the railroad track that controlled by turnout motor, therefore it is one of important railways elements for guiding and directing the train to not derailment or collide with another train. The device was made in order to check the reliability of turnout machine in railway systems. In Indonesia, currently the inspection of turnout machine was done manually and still not so efficient in term of the process. Here, we built a portable system device consisted of load sensor, processed with a microcontroller and the data were recorded and displayed in a Liquid Crystal Display (LCD). The device was tested directly to a turnout machine on the railroad at Kiara Condong Station, Bandung, Indonesia. The measured results showed that the device working properly and the average pulling strength of turnout machine at the station was 256.6 ± 2.88 kg.
