Abstract

Presently, biomass is mostly utilized as co-fuel in coal combustion in view of energy diversification and emission reduction. However, since the coal content of bio-briquettes is high (up to 80% in this study), gas emissions such as those of SOx still occur. Therefore, the introduction of SO2adsorbent is common in coal briquette or bio-briquette combustion. A calcium-based material is usually used for this goal. The aim of this study was to observe the effects of desulfurization temperature and Ca/S ratio (Ca = calcium content in adsorbent; S = sulfur content in coal and biomass) on desulfurization efficiency and kinetics. The ratio of coal to biomass (palm kernel shell/PKS) was fixed at 90:10 (wt/wt) and the ratios of Ca to S were varied at 1:1, 1.25:1, 1.5:1, 1.75:1 and 2:1. The mixtures of coal, PKS and adsorbent were briquetted at a molding pressure of 6 ton/cm2 with Jatropha curcas seeds and starch mixture as binding agents. Desulfurization was performed within a temperature range of 300 to 500°C for 720 seconds at an airflow rate of 1.2 L/min. The results showed that the highest desulfurization efficiency (90.6%) was associated with the Ca/S ratio of 2:1 and temperature of 400°C. Moreover, the highest reaction rate constant of desulfurization was 0.280 min-1.

Abstract

Coconut fibre which is extracted from outer shell of a coconut is a type of natural fibre used as composite board reinforcement in this research. The fibrebinder used in this research was stryrofoam which is a material from polysterene. This research was aimed at finding out the appropriate composition by weight between coconut fibre and polysterene and to find out the physical, mechanical and morphological characteristics of composite board resulted from the engineering process. The construction of composite board was started by cutting the fibres with the length of ≤ 5 mm, then dyeing them into NaOH for 4 hours. After those process, the fibres were dried and weighted. The Styrofoam was dissolved into silane before it was weighted based on its composition. After the coconut fibre and polysterene mixtures were mixed,they were poured into the composite board mold. The benefit of this composite board is that it is more water resistant. The test results for tensile, density, moisture content, and thickness swelling meet the Indonesian National Standard (SNI) 03-2105-2006. The flexural strength of composite board which meets the standard is the compositions of 30:70, 40:60, and 50:50, while the compositions of 60:60 and 70:30 do not meet the standard.

Abstract

This research study drilling quality for polyester composites with glass fiber reinforcement and polyester composite with fiber reinforcement Biduri fruit due to the influence of cutting parameters. The test is performed with the variation of machining process parameters varying the diameter of the cutting tool 5 mm, 10 mm, 14 mm, and a cutting speed of 30 m/min, 60 m/min and 90 m/min which feeds the parameters fixed. The test material used is a composite material with glass fiber reinforcement and composite with natural fiber amplifier with a size of 150 mm x 50 mm x 20 mm. The process of making composites made using hand lay-up method. Test results greater tool shows, the better the quality of the resulting hole. Due to the use of a cutting tool diameter of 5 mm would result in a continuous rage so that it will stick to the cutting tool and can interfere with the cutting tool. Cutting speed, the cutting results, the greater the cutting speed, the better the results are also cutting. Because the higher the cutting speed, the resulting fury will be more and continuous so as not to interfere with the process of cutting.

Abstract

Oil palm empty fruit bunches (OPEFB) is one of the palm oil industry solid wastes that can be used as an alternative material to product composites. This research was conducted to determine the effect of the addition of Zinc Oxide (ZnO) as a filler material hybridized with OPEFB fiber to the flexural strength of polymeric foam composites. The aim of this research is to obtain the strength of the flexural test value of the composite material polymeric foam reinforced OPEFB fiber and Zinc Oxide (ZnO) with reference to the ASTM D790-92 standard. The composition of the specimens are 70% Resin, 15% OPEFB Fiber, 15% Polyurethane with different fiber sizes namely mesh (40, 60, 80, 100) and the addition of Zinc Oxide (ZnO) of (0%, 5%, 10%, 15%, 20%). The test specimen used for each composition is 5 samples, so that the entire test sample is 100 samples. From the test data it can be concluded the value of flexural strength in the 100 mesh OPEFB specimens and the addition of Zinc Oxide (ZnO) 10% is the best composition compared to 40, 60 and 80 mesh OPEFB with the addition of Zinc Oxide (ZnO) 5%, 15%, and 20%, where the voltage value is 10,01141 MPa and the strain value is 0,898456 mm / mm. From the research data it can also be concluded that the smaller the OPEFB fiber size with the addition of zinc oxidation (ZnO) 10%, the flexural strength of the polymeric foam composite material will be better.

Abstract

The primary structural component supporting the other structural loads in a building is the beam-column joint. It is considered a critical area of a building which needs to be accurately designed to ensure energy is dissipated properly during the occurrence of an earthquake. Beam-column joint has the ability to offer a proper structure required to transform cyclic loads in the inelastic region but also has a direct impact on the components connected to it during the occurrence of any failure. This is one of the reasons the beam-column connection needs to be designed carefully. Therefore, this study focused on designing a beam-column joint with reinforcement according to SK SNI T-15-1991 in order to withstand cyclic loads. The test specimen used was observed to have a concrete compressive strength of 19.17 MPa while the dimension of the beam was 120 x 30 x 40 cm and the column was 30 x 30 x 200 cm, having 8Ø13.4 mm bars with 310.03 MPa yield strength (fy) as well as Ø9.8-100 mm stirrup reinforcement with (fy) 374.59 MPa. The test was initiated through the provision of 0.75 mm, 1.5 mm, 3 mm, 6 mm, 12 mm, 24 mm monotonic cyclic loads at the end of the beam up to the moment the specimen cracked. A maximum load of 68.35 kN for the compression and 49.92 kN for the tension was required to attain the cyclic load capacity. The maximum load was attained at 50.98 mm displacement. Furthermore, beam-column with 23.93 mm displacement caused a reduction in capacity. Meanwhile, the load at 24 mm produced the cycle's highest dissipation energy of 13.25 but this can be increased through the addition of stirrups to provide stiffness in the joint. The stiffness value was also observed to have increased after the structural repairs.

Abstract

Jaloe Kayoh is a traditional canoe used by Aceh's fishing communities to catch fish in downstream rivers and shallow waters. The current Jaloe Kayoh design does not meet ergonomic aspects, especially in the user's seat position component. It is known from the results of distributing the Nordic Body Map (NBM) questionnaire at the initial stage of the study which was distributed to 30 respondents, that 9 out of 27 fisherman's body parts were in the "very high" complaint score. This complaint is also supported by data on the user's sitting position by bending the legs to form an angle of 70°, while the ideal sitting position is with the body upright and bending the legs at an angle of 90°-135°. Because this can lead to complaints that have an impact on the risk of long-term injury such as Musculoskeletal Disorders (MSDs) so this study aims to design a seat for Jaloe Kayoh users according to anthropometric measurements to avoid the risk of long-term injury. The design of the Jaloe Kayoh stand was carried out using the anthropometric approach of Acehnese fishermen and the Quality Function Deployment (QFD) method as a reference for researchers to determine the design according to the wishes of the user. The anthropometric dimensions used in this design are popliteal height (PH), buttock-popliteal length (BPL), hip breadth (HB), backrest height (BH), elbow rest height (ERH), and shoulder breadth (SB). Data Calculation from anthropometry produces the 5th, 50th and 95th percentile measurements, which will be used in designing the seat position for Jaloe Kayoh users. The three percentile values result in a new measure of the design; PH is 39.31 cm; BPL of 48.43 cm; HB is 40.31 cm; BH is 61.37 cm; ERH of 100o; SB is 52.26 cm. So based on the QFD method produced by the house of quality, it produces a design for the Jaloe Kayoh seat position that is in accordance with what the user wants
