Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

One of the main parameters in planning the construction of bamboo mattress poles is the stiffness of the bamboo mattress. The elements of mattress stiffness are the moment of inertia of the mattress (Im), the modulus of elasticity of the mattress (Em), and the cross-section of the mattress (Am). This research will examine the rigidity element of bamboo mattresses. The research method used was to record physical data of general bamboo at random with a minimum outer diameter of 6.0 cm and a length of 5.0 m. The bamboo is assembled into a mattress with ties. The width of the mattress is 1.0 meter. Mattresses are arranged in 1 ply, 3 plies, and 5 plies. Each type of bamboo mattress is tested for its flexural strength until it collapses. The recorded data are load (P) and deflection (δ). The analysis was carried out to determine the relationship between the number of mattress layers and the stiffness parameter of the mattress. The results showed that there was a relationship between the number of layers of the bamboo mattress and the parameters of the stiffness of the bamboo mattress, with the equation: Y = 45958 X(0,3864); where X is the number of layers of the bamboo mattress, and Y is the flexural parameter of the woven bamboo (Em, Em.Im; or Em.Am).
Badak LNG Plant produced Liquefied Natural Gas (LNG) from natural gases. Previously, they produced 1 type of LNG product with calorific value (> 1108 BTU/SCF) or Rich LNG, now they produce Lean LNG products with calorific value (<1108 BTU/SCF). Testing of Rich LNG product is carried out with the standard calibration of Rich LNG gas, which it so far has been successfully carried out with valid measurement data with evidence of comparative testing between LNG terminals. For this new Lean LNG product, the testing has never been done before at Badak LNG, so it is necessary to conduct research on optimization and innovation of gas using for calibration of gas chromatography equipment against the test results. The research stage that will be carried out, it is to verify the performance of agilent GC tool 6890 and 6890N. Then, Lean LNG products are measured using Rich LNG and Lean LNG gas standards. Then, from the results of the two measurements, they were compared with the statistical test method based on the repeatability and reproducibility of the 2261-2020 GPA method to determine whether or not the measurement was accepted by testing. The final stage is to be modeling the determination of gases standard concentration, for the components of methane (CH4), ethane (C2H6) and propane (C3H8). The results of this study indicate, if there is no significant effect in testing the value of standard concentration from Rich LNG gas used for calibration of GC equipment on the results of testing Lean LNG products, the concentration (%-mol) of nitrogen 0.030%, methane 3.978%, ethane 3.182%, propane 1.823%, i-butane 0.449%, n-butane 0.514%, i-pentane 0.020% and n-pentane 0.005%. The validation results of Lean LNG product test results on the Agilent 6890 and 6890N GC referring to the GPA 2261-2020 standard showed that the deviation was still acceptable for testing use. The result of modeling from the standard concentration of LNG for Lean LNG products is obtained by the equation y=ax (value must be included). So, the results of deviation quantity between the sample concentration and the Rich LNG gas standard used for calibration with results that fulfill the requirements for acceptance test.
