Published: March 2020

Titanium alloys, such as Ti-10Ta-2Nb-2Zr (TTNZ), are promising biomaterials due to their excellent biocompatibility and low Young’s modulus. The TTNZ samples herein were manufactured by selective laser melting and the novel material was evaluated as a dental implant in vitro and in vivo. The microstructure, mechanical properties, electrochemical behaviour, cytotoxicity, haemocompatibility and osteogenic differentiation were systematically investigated. Based on the tensile test results, the as-printed TTNZ samples had an elongation of 20.23% ± 1.95%, an ultimate tensile strength of 646.61 ± 24.96 MPa and a Young’s modulus of 23.72 ± 1.18 GPa. According to the biocompatible value, the as-printed TTNZ sample exhibited no cell cytotoxicity and it showed even better cell adhesion ability than that of the as-printed Ti-6Al-4 V and wrought Ti-6Al-4 V samples. The haemolysis percentage of the as-printed TTNZ sample was 0.629% ± 0.363%. Moreover, the as-printed TTNZ sample facilitated protein adsorption and osteogenic differentiation of human osteoblast-like (MG-63) cells in vitro. The in vivo data also demonstrated the histocompatibility of the as-printed TTNZ. In summary, the as-printed TTNZ developed in this study demonstrated good biocompatibility, low stress shielding, excellent ductility and great osteogenic differentiation. These results indicated that as-printed TTNZ alloys can be promising for end-use human biomedical applications.

Durability and strength improvement of clayshale using various stabilized materials
Authors: Faray  , Rahayu Wiwik
Published: March 2020

In Indonesia, the study of clayshale has begun to be widely discussed. Clayshale is well known as a degradable material. The process of degradability in clayshale shows the weakening of the shear strength. This clayshale characteristic leads to several failures in the geotechnical design. To avoid degradability, soil stabilization testing was carried out by using cement, lime and rice husk ash. In the soil stabilization study, the use of cement and lime is already common and effective for some type of problematic soil, but the cost of material production is expensive and not environmentally friendly. Rice husk ash as agricultural waste material has the potential as a stabilizing material because it is availability and reaction ability with lime as known pozzolanic reaction. From the test results, each mixture has different response and potency. Cement has better resistance to wetting and drying with a significant increase in unconfined compressive strength. Whereas the lime itself did not significantly increase durability and unconfined compressive strength, but the effect of rice husk ash to the soil-lime mixture increasing durability despite the reduction in unconfined compressive strength.

Published: March 2020

Runoff coefficient or Curve Number (CN) is a parameter value needed to describe runoff in accordance with the intended land use. In determining CN values, it is necessary to take account the Hydrologic Soil Group. The Hydrologic Soil Group (HSG) consists of 4 groups, which are: A, B, C, and D. In order to classify the appropriate HSG, several methods can be used, namely: soil properties, soil maps, or minimum infiltration rates. In this research, an HSG classification distribution analysis will be carried out based on the infiltration rate obtained from actual conditions found during observation in the research site. This research was conducted in 13 locations, situated in the Upper Ciliwung watershed. The division of 13 locations is based on the distribution map of the HSG according to the Geological Information Agency and also the map of the distribution of Upper Ciliwung sub-bases. In its classification, each HSG has a different infiltration rate value. In this study, an analysis of the distribution of HSG classification based on the infiltration rate was obtained from direct observation on the research site. The study was conducted using a double-ring infiltrometer. The data obtained from the study were then processed using parameter estimation and the Horton Method to obtain the Horton infiltration rate. When the infiltration rate value is known, the corresponding HSG can then be determined for the soil at that particular location. With Inverse Distance Weighted in ArcMap, a map of the spread of infiltration rate and classification of HSG will be obtained in the Upper Ciliwung watershed. The infiltration rate obtained in the Upper Ciliwung watershed ranges from 0.15-12.6 cm/hour. The distribution of HSG is also found in the Upper Ciliwung watershed, consisting of groups A, B, and C.

Published: March 2020

Most of the soil in the universe contain organic matter that results on the negative effects on the shear behavior of soil. The objective of this research is to study the effect of organic content and proportion of cement of artificially cemented soil. A compaction and direct shear test without curing period were undertaken on the soil with 6, 11, 16, and 21% organic content. Direct shear test results show that the soil cohesion decrease and internal friction angle slightly increase as increasing of organic content. The direct shear test of artificially cemented soil with 21, 28, 42, and 56 curing time was then performed to investigate the effect of cement quantity on the shear behavior of cemented soil. The cement content was 25, 50, 75, and 100 kg/m3. The more cement quantity added to the soil, cohesion and friction angle of artificially cemented soil improves. There is also improvement of the shear stress due to the increase of cement proportion. Similarly, shear strength of stabilized soil improves inherent with curing period due to the short and long-term pozzolanic reactions.

As interface shear strength has become one of the growing topics in research, this paper summarizes and discusses the research development of interface shear strength and its possibility to explain the interface shear behavior at a slope. The discussion was limited to cohesive soils and experiment-based behavior of the interface shear. Some research has been selected in order to understand the development of interface shear strength through time and two examples of slope interlayer shear behavior were selected. It was known that there are three common tests of interface shear behavior used: simple shear, direct shear, and ring shear test. The development of interface shear strength started at 1960s between soil and construction materials where the four major components were defined. As the research grows, many other types of soils, interfaces, and the effect of the tests became the topic of the research. In the end, the examples given from modeling the interface shear behavior from a slope gives a new perspective of cases for interface shear strength in slope analysis.

There are some reasons as a background for preserving the architecture building, one of them is nostalgic reason, “Old buildings have intrinsic value and are reminders of a city’s culture and complexity [1]. The nostalgic reasons is refer to a feeling or inspiring nostalgia [2]. The architecture and interior elements are among that create the nostalgic reasons of one place. Using mixed methodology between qualitative and quantitative, this research aims to overview the architecture, interior and some famous food that people remember about Metropole XXI building in Jakarta. The research found that some architecture and interior elements are among of what people remember about Metropole XXI as nostalgic reason that could help for future research on preserving this building as one of the oldest and well maintain historical building in Jakarta. The research also found that the nostalgic reason would lead to sustainable design for architecture and interior works because of its strong bond to the people who has their emotional closeness.

Energy used in multi-storey office building is mostly for air conditioning, and it is acknowledged that the energy could be minimized by reducing the cooling load. In general, the cooling loads are from internal and external heat. The external heat plays significantly in determining the cooling load; therefore, it is necessary to reduce the amount of solar radiation received by the external surface of the building. The objective of the paper is to investigate the reduction of solar radiation received by the surface of the multi-storey office building by applying parametric design study and to add a building envelope as the secondary skin as well as the architectural element. There are two steps of analysis in the methodology, (1) to conduct solar radiation analysis, and (2) to conduct building facade analysis. In the process, four alternatives form were simulated to obtain the most optimum shape in relation to the incident solar radiation reduction. The final parametric study results of the solar radiation and building facade analysis showed that the reduction of the irradiance is around 25% with the additional facades.

In textile industries, the dyes are commonly used and creating a waste of dye in drainage stream water. To overcome this matter, the removal of dyes are needed by using activated carbon. The precursors of activated carbon can be prepared by various organic materials with high level of carbon content. Pinang frond was being selected for precursor of activated carbon in this study, and named as PFAC. This PFAC was used to adsorb methylene blue (MB) as a media for removal of MB. The aim of this study is to determine the optimum operating parameters such as CO2 flow rate (mL/min), activation time (hour) and activation temperature (°C)for the better removal of MB by using response surface methodology (RSM) as an experimental design (DoE). The 476 mL/min CO2 flow rate, 6.0 hour activation time, and 867°C activation temperature were become the optimum operating parameters of PFAC in this study.The model developed by RSM shows that less than 2.5% error in comparison with the experimental data, hence it can be used for prediction of the fixed responses of operating parameters. The pseudo-first-order model was matched with the MB adsorption kinetic.

One of the important activities to achieve a sustainable palm oil company is by improving the sustainable supply chain management, especially being in line with the lean and green SCM concepts. The lean concept aims to reduce costs and to increase the effectiveness of the supply chain. While the green concept tries to ensure that the ongoing process keeps bringing good effect on the environment. In designing the performance measurement of the sustainable supply chain through the lean & green supply chain management approach, this study includes a formulation for Key Performance Indicators (KPI) and grouping of the lean and green indicators which are integrated with the balanced scorecard (BSC) perspectives. It obtained 28 KPIs which consists of 15 lean supply chain KPIs and 13 green supply chain KPIs. Based on overall weighting, the highest priority KPI is the company’s total revenue and total operating costs, followed by the total cost of the supply chain (all of them are from a financial perspective). The weights of three KPIs are 0.103, 0.078 and 0.072 respectively.

Problem identification is a critical step to resolve the delay problem in many industries.Fishbone Diagram is one method that is widely used to explore various alternative causes of problems.Other approaches are still needed to define the level of significance of the relationship between each alternative cause of the problem with the perceived problem.The Decision Tree with C5.0 and J48 algorithm approaches are used to classify enormous amounts of data. This study used these algorithms to obtain the root cause of delay. The calculation of information gain shows that most influence variables for the classification process of delay are warehouse capacity and quote order lead time.
