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 500Â°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 400Â°C. Moreover, the highest reaction rate constant of desulfurization was 0.280 min-1.

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.

The use of thermal insulation materials in buildings is an important topic in an effort to increase the efficiency of electrical energy consumption. Natural fiber-based thermal insulation material is an alternative to the synthetic fibers that are widely used today. It is important to know the thermal stability of the materials as the basis for its feasibility as a thermal insulation material. Palm wood (OPW) and ramie fiber (RF) have potential as raw materials for thermal insulation from natural fibers. This study aims to assess the thermal stability of oil palm wood and ramie fibers as raw materials for thermal insulation materials based on natural fibers. Oil palm wood particles and rami fiber were treated before being tested. Oil palm wood is soaked in hot water 1000C for 30 minute and ramie fibers in 5% NaOH solution at the same time. Thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) tests were carried out to obtain the thermal characteristics of the two raw materials. Tests were carried out for both fibers, untreated and treated. TGA testing resulted in OPW and RF with treatment having better thermal stability than OPW and RF without treatment. OPW and FR with treatment have maximum thermal stability at temperatures of 3770C and 3990C. DSC analysis showed that OPW and FR with treatment produced peak temperatures at 4090C and 4080C respectively. The thermal stability of fibers will increase with treatment compared to untreated fibers.

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.

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
