Published: May 2020

Abstract
Formwork is a molding tool to get the shape of concrete to work as planned. The cost of making formwork is proportional to the cost of reinforced concrete work, so the right methods and strategies are needed to calculate the cost of formwork that can be used repeatedly. When making a bill of quantities, the cost of formwork used is adjusted to the work item, and in the calculation, the formwork that has been used in one application is no longer used for the next. But the reality in the field formwork can be used repeatedly with the right methods and strategies so that the cost for making formwork can be efficient by applying green construction strategy with the Reuse concept. This study aims to determine the methods and strategies as well as the percentage of green construction using green formwork for each building floor. The research method used is qualitative and quantitative methods. Qualitative methods are used to collect data through observation, interviews, and documentation related to the use of formwork in projects. Quantitative methods are used to calculate the cost of formwork for semi-system methods and one-floor rotation strategies. The results of the research found are the semi-system method and one-floor rotation strategy resulting in the formwork cost savings by 36.10%, and the reduced material on the application of green construction can reduce material successively by 8% for the second use, 16% for the third use, and 24% for the fourth use. This finding contributes to the list of work analysis related to formwork making.

Published: May 2020

Abstract
Plants litter as soil organic matter turn over to soil by the decomposition process. Decomposition is regulated by environmental factors, such as soil water content and pH. High water content (90%) and pH 6.2 increased CO2 gas production rate, lowest water content (30%) and pH 4.9 increased NH4
+ N-mineralization into the soil as decomposition result. In this study, we investigated cacao leaf litter decomposition in soil. Cacao leaf litter was applied in a 100 mL polypropylene bottle with 70 g air-dried soil, but only the soil was applied as a control. For the litter-amended treatments, 2 g (oven-dry weight) with 2 mm sized cacao leaf litter was placed on the soil surface. The treatment with different soil moisture and pH regimes were soil moisture and pH of 30% and 4.9 (SLWC30i), 30% and 6.2 (SLWC306), 60% and 4.9 (SLWC60i), 60% and 6.2 (SLWC606), 90% and 4.9 (SLWC90i), 90% and 6.2 (SLWC906), respectively. All treatment was incubated at 25°C under the dark condition for 28 days. Extractable NO3
− and NH4
+ concentration, and soil greenhouse gas (CO2, CH4, N2O) were measured. Highest extractable NO3
− and NH4
+ concentration showed in SWC906 (30.7 mg N kg−1) and SLWC606 (87.1 mg N kg−1), respectively. Soil greenhouse gas production rate highest in water content 90% pH 6.2, CO2 was 3.82 kg C period−1, CH4 was 0.0089 kg C period−1, N2O was 0.016 kg N period−1.

Abstract
This study aims to correlate fixed carbon content using proximate analysis and calorific value analysis of the South Sulawesi Mallawa Formation coal. The study was conducted at two locations, namely in the Massenrengpulu Region of Bone Regency and Pujananting Region in Barru Regency. The research method used is the collection of field data each using the channel sampling method (ply by ply), which represents the lower layer, middle layer and upper layer. Then a proximate analysis is performed to obtain a fixed carbon content and an analysis of the calorific value. The results of the analysis show that, coal in the Pujananting area shows a correlation between the percentage of fixed carbon and the calorific value has a very good correlation with the linear regression value of 0.9994. Similar to the Mallawa Formation coal in the Massenrengpulu area, the correlation of fixed carbon content and calorific value shows a very good correlation with a linear regression value of 0.9998. An increase in the percentage of fixed carbon in coal will be followed by an increase of calorific value. This increasingly shows a very strong correlation between fixed carbon content and calorific value in coal.

Published: May 2020

Abstract
This article, proposing Quality Function Deployment (QFD) as a product and service design technique, can be used to make decisions. Implementation of the process is done by conceptualizing problems, collecting data, and analyzing and reporting results. In this process, the required product innovation as well as the needs of the employees, as internal organizational clients, are determined. These results are then used to design KPIs that relate to consumer perspectives as well as internal perspectives. This framework is manifested in a diagram called the House of Quality (HOQ). Nevertheless, as a tool developed from practical level, little theoretical and empirical reviews attempt to provide sufficient information to assure the benefits of QFD in the transport context. Therefore, we review the theoretical foundations that can be used to support QFD and present a number of empirical findings from the literature that can be used to evaluate the feasibility of QFD in the selection of modes of transport. Because it is a practical tool, QFD is rarely discussed through theoretical approach. QFD has no theoretical basis at all. However, it is important to support QFD from the relevant theoretical aspects to explain how this system can work in promoting the improvement of product and service quality.

Abstract
Pervaporation is currently used for brine water desalination. This high water salt content may impact the environment if it may not be treated. So, in this paper demonstrates the performance of organo-silca membrane to produce potable water from brine water. Organo-silica membrane was employed by sol gel process for 3 hours using tetra orthosilicate (TEOS) as precursor as well as dual catalyzed (organo catalyst/citric acid) and base (ammonia) on reflux temperature of 0°C. The molar ratios were 1:38:0.0007:5:003 for TEOS:EtOH:Citric Acid:H2O:NH3. Organo-silica membrane was applied in various artificial brine water (7.5-15 wt % NaCl) operated at 40 and 60°C as feed temperatures. The citric acid was chosen as carbon source to increase the carbon chains in the silica matrices. It was found that the water flux was increased as the feed temperature also increased from 40°C (1.27 kg.m2.h−1) to 60°C (1.55 kg.m2.h−1). Organo–silica membranes can produce water with a salt rejection of >90%.
