Published: March 2021

Abstract
Monitoring is a set of activities carried out to measure the achievement of objectives. One area that requires a monitoring system is the production process, this aims to ensure that production can be controlled and run as it should. Lack of monitoring of production can cause problems. Although there has been a lot of research on the production monitoring system, so far there has not been much mention regarding the provision or sharing of information on the progress of production implementation in more detail between the production department and the parties involved, especially in sharing information handling errors that occur during the production process. This is important because mistakes that occur during production can cause delays in shipping and will have an impact on the valuation or reputation of the company. The results obtained from the implementation of the system based on user acceptance testing is getting a level of acceptance of 81.5% of 42 test scenarios for 4 types of users. Implementing a production monitoring system can help in monitoring production. More interesting studies can be further carried out especially in the area of artificial intelligence for monitoring production systems.

Abstract
Medicinal plants (herbs) are plants that are known to have certain compounds which are nutritious for health. In Indonesia there are 30,000 types of plants and 7000 of them are classified as medicinal plants (herbs). The human body is complex and organic, while chemical medicines contain chemicals that are inorganic and pure. Therefore, chemical medicine are considered not very suitable for consumption by the human body, which if consumed continuously can even be bad for human health. However, some chemical drugs are actually symptomatic (temporary) so they must be taken for life by patients with certain diseases. Therefore a system is needed to be able to help the community to recognize medicinal plants better, in this case the medicinal plants are focused on the introduction of medicinal leaves. In this study identification of medicinal plant leaves was carried out using the Convolutional Neural Network method. This research will build a system of identification of medicinal plant leaves by using Convolutional Neural Networks. Using training data that is carried out in a computer set and then implemented in mobile-based software to recognize the types and benefits of medicinal plant leaves identified.

Abstract
In face milling process of train wheel, cutter is one of the most important part and this part should be monitored from failure phenomena for improving final products of train wheel during machining process. One of the best ways for face milling tool condition monitoring is by analyzing signal. However, noise usually contaminates the measured signals during measurement using any sensors. This study presents the effect of noise on the Hilbert-Huang transform features for face milling condition monitoring by mean analyzing the synthetic vibration signals. First, noisy synthetic signals were created, then separates them by Empirical Mode Decomposition (EMD) to be intrinsic mode decompositions (IMFs). Second, the Hilbert-Huang spectra were generated and then compared to HHT baseline spectrum. The result showed that the noise disturbed the HHT spectrum. Without filtering signal, the face milling cutter condition phenomenon was difficult to be revealed by HHT.

Published: March 2021

Abstract
The mould is most imfortance tools for large production for example in automotive industry. The cost of mould is highly dependant on part geometrical complexity and material selection. Steel has long been used as a material for making moulds, although new materials such as plastics and composites have been discovered. However, steel maintains its position above material selection because of its mechanical properties. This research uses Assab 705 steel, because Assab 705 steel is classified as medium carbon steel (carbon content of 0.38-0.43%) and has the ability to be hardened through a heat treatment process. Application of Assab 705 steel is widely used for making bolts, tools and various kinds of moulds. The heat treatment process carried out in this study is by heating the steel sample with a temperature variation of 750, 800, 850 and 900°C and continued with the quenching process using Olie SAE 90 as cooling media. Steel samples that had been heat treated were tested by Rockwell hardness and micro structur changes were analyzed using optical microscope. Based on the results of rockwell hardness testing that the highest hardness value was achieved at 54.5 HRC in samples that have been heat treated at 900°C, which when compared to hardness samples without heat treatment, there has been an increase of 60.30%. The microstructure of the Assab 705 steel sample changed after the heat treatment process, which formed a martensite phase and tended to increase with increasing heat treatment temperatures.

Abstract
Andara granosa shell is one of the bivalves that is found in Indonesia. The high level of andara granosa is meat consumption without being followed by right processing of the shells, makes andara granosa shells become a waste that distrupts the environment. Andara granosa is contain a lot of CaCO3 Andara granosa shells contain a lot of CaCO3 which makes it can be used as a coagulant. Shells containing CaCO3 are converted into CaO (Calcite) first by the process of calcination. In this study, calcite was obtained through the process of calcining of andara granosa shells at 800 °C for 4 hours, which was dried and destructed before. The calcite optimization test in andara granosa is done by analyzing the ratio of calcite concentration variation (600 ppm, 700 ppm, 800 ppm, 900 ppm, 1000 ppm) to the decrease in BOD, COD, and TSS values in industrial liquid waste. The test results show the optimal optimal decrease in BOD, COD, and TSS values is at a concentration of 900 ppm with an effectiveness of 80.53%. The relationship between the concentration of coagulant to decrease in BOD value is shown by the equation y = -6.7043x2-50.275x + 599.83 and R2 = 0.9356,% effectiveness of COD 81.16%. The relationship between the concentration of coagulant to decrease in COD value is shown by the equation y = -4.3214x2-130.15 x + 1033.4 and R2 = 0.9492,% effectiveness of TSS 96.10%. The relationship between coagulant concentrations and the decrease in TSS values is shown by the equation y = 32.611x2-304.24x + 697.95 and R2 = 0.9088. Thus calcite with raw material of blood shells can reduce the optimal BOD, COD, and TSS values at a concentration of 900ppm.

Published: March 2021

Abstract
Natural radionuclides Ra-226, Ra-228 and K-40 along three (3) stations in Middle Langat River Basin were collected over a 9-year period at 3 months interval. Variations of activity concentration in the catchment soil and river sediment samples were analysed using HPGe detector to identify temporal and spatial trend. Activity concentrations show indication of long-term fluctuation especially for K-40, but will require long data for further validations. Increased activity concentrations in the down-river direction suggests a couple catchment loss and river sediment relative gain based on analysis of the ratios between element pair. Correlation of Ra-226 and Ra-228 is very strong, but their correlation with K-40 varies considerably possibly due to the high potassium solubility.

Abstract
Environmental sustainability practices in facilities management (FM) are vital in reducing the impact of buildings on the natural environment, and such practices can provide a significant contribution to university achievement in terms of reducing cost, improving efficiency, and expanding the value of an investment. The present investigation deals with environmental sustainability practices that are concerned with climate change, ecosystem health, biodiversity conservation, and resource consumption. The aim is to determine the extent of environmental sustainability adoption in FM practices for Malaysian universities. An online questionnaire survey was undertaken to key practitioners in the FM office who have essential roles in sustainability implementation. The questionnaires were administered to 18 public universities with a total invitation of 88 participants and 65% response rate. Generally, universities in Malaysia showed some commitment in FM practice towards environmental sustainability with some focused-on programs of emission control (3.94), water conservation (3.81), biodiversity preservation (3.79), and energy efficiency (3.71) programs. Specifically, in the three FM phases, namely, in operation and maintenance, in renovation and refurbishment and demolition and rebuild works, the results showed no significant differences. Indeed, environmental sustainability is equally adopted in whole FM phases for Malaysian universities.

Published: March 2021

Abstract
Mass urbanization and rapid global population growth lead to the occurrence of dense urban areas. For buildings located in densely built urban areas, there are minimum horizontal green spaces. One practical idea to increase the presence of green is to plant upwards when horizontal space is a constraint. This research is done for the case in Malaysia as Malaysia have yet to emerge in vertical greenery implementation for buildings. The aim of this research is to determine the significances of implementing vertical greenery. The second aim is to identify the barriers to the implementation of vertical greenery and the final aim is to provide practical approaches as well as recommendations to increase the adoption of vertical greenery in Malaysia. The methodology of this research is qualitative method whereby interviews are conducted. Vertical greenery is introduced to provide environmental, economic and social benefits. For environmental issues, the temperature can be reduced and energy efficiency can be improved. Economically, vertical greenery can assist in energy savings and improve acoustic insulation. As for the social impacts, the presence of vertical greenery provides pleasing and better environment for the community. With these three aspects, sustainability can be achieved. The main barrier to the implementation of vertical greenery is due to the high cost of construction. The government should place more emphasis on implementing vertical greenery as it is considered as a promising solution to bring significances.
