Abstract

Rasbora sumatrana or locally known as “seluang” in Malaysia is a pelagic fish. Unlike its other congeneric species is not categorized as an ornamental fish. Samples of the presumed R. sumatrana was obtained from an abandoned swamp in Hulu Langat, Selangor. Initial identification of the samples was conducted based on meristic and morphometric analyses, which showed congruence with R. sumatrana when referenced to FishBase. To complement the analysis, a molecular study was conducted based on the cytochrome oxidase subunit I (COI) DNA barcoding marker. Confirmation of the species identity was done by BLAST results with six voucher sequences of R. sumatrana and other Rasbora species from GenBank. The relationship of Rasbora spp. was analysed by phylogenetic and Automatic Barcode Gap Discovery (ABGD) analysis. Contradicting with morphological and meristic data analysis, both Maximum-Likelihood and Maximum Parsimony phylogenetic tree showed that the currently studied samples did not cluster with R. sumatrana. We believe that they may represent cryptic diversity and are tentatively classified as Rasbora spp.

Abstract

Allium cepa test is widely used to evaluate the effects of water pollution based on dividing cells since it is a very sensitive tool for prediction and recognition of environmental stresses. This study aimed to evaluate the potential use of A. cepa as a molecular biological indicator to detect the presence of water pollution. A. cepa roots were exposed to water samples at 24 and 48 hours with tap water and hydrogen peroxide solution as controls. The effects of water sample exposure on A. cepa were analysed based on the plant cytotoxicity, genotoxicity, and expression of stress gene between test samples and control sets. The findings showed no significant changes observed in mitotic index of A. cepa exposed to water samples compared to negative control. There is also no expression of alliinase gene was detected. However, there is chromosomal abnormalities observed in A. cepa exposed at 24 and 48 hours. The chromosomal abnormalities detected include lagging chromosome, c-mitosis, disrupted anaphase, disrupted metaphase, spindle disturbance, and stickiness. Our study shows that molecular biological method could be a potential method to serve as an effective, sensitive, and useful marker for water pollution determination.

Abstract
This article aims to answer how State Law regulates the existence of local wisdom related to disaster mitigation in coastal areas? How is the ideal adoption of customary law by State Law that will contribute to the disaster mitigation process of coastal area based on local wisdom? There is a most basic difference between State and Customary Law regarding disaster mitigation in coastal area. There are things that make it possible to reconcile through the harmonization of laws related to the legal functions positioning, both State Law and Customary Law. However, this step is not simple, because it must be preceded by the integration of Customary Law and State Law. This writing will apply a qualitative approach, by setting the law in an interdisciplinary study, allowing what is stated in law through fisheries assistance. Theoretically, this integration is known in the legal pluralism, where State Law recognizes the existence of Customary Law. Meanwhile, at the practical level, state legal instruments have begun to be built that allow recognition of Customary Law. With its position and function, there is a number of possible parts are used as meeting points between the pantang (taboo) areas and the fisheries conservation area. Conservation areas that are very strict, must be positioned in a social justice reality, as has been known and applied through pantang areas.

Published: March 2021

Abstract
The rapid growth of global e-commerce prompts the need of efficient warehouse handling and logistics, forcing manual operations to be replaced with automatic systems. An example of automated solutions is the smart packaging system for boxes which can simulate optimized box arrangements in order to save space. Even though three-dimensional bin packing problem has been studied widely to optimize box arrangement, only a few studies have been done to automatically detect box sizes. Box size detection is important to increase the effectiveness and efficiency of the packaging process as well as providing fast and accurate input for the box arrangement optimizer. Therefore, this paper presents the development of a machine vision system for automatic box size detection in 3D to support a smart packing simulator. The system uses a single camera and a platform covered with square grids prints. The box size detection algorithm was based on the localization of the platform area and it works by applying the bilateral filtering, binary thresholding and morphological image transform for the square grids feature extraction. To measure the box size, the length, width, and height of the boxes were detected by referencing it to the count of the square-grids. The volume of the boxes was further computed from the three-dimensional values obtained. The performance of the algorithm was then evaluated by calculating the error against the true value obtained from the manual measurements. The average accuracy for box size detection was 94.3% and analysis shows that the accuracy of the model was highly dependent on the size of the square grids on the platform. The result shows great potential of using a single camera system for automated 3D box size detection.

Published: March 2021

Abstract
The activity of squatting and bending can cause an awkward working body posture and the risk of Musculoskeletal Disorders (MSD). This is mainly happening in the cutting machine process as a workstation that needs high precision so that it requires close eye contact with the workpiece. Through an initial assessment using an NBM questionnaire, it is obtained that almost all of the Cutting Operator’s body parts are uncomfortable after finish working. A further investigation is done towards two healthy males (height 169 ± 1.4 cm and weight 73.75 ± 2.5 kg) by capturing the current working body posture and then to be translated to a virtual model and virtual environment, by using JACK 8.2 software. The MSD risk parameters are using PEI by processing LBA, OWAS, and RULA data. Improvement of the posture is done by enhancing the workstation through virtual simulation so that the PEI on the two operators are decreasing from 2.81 and 2.43 to 1.52 and 1.12. Unexpected things happen in this semi-manual cutting workstation, the awkward posture is inevitable as seen in the RULA output of the improved workstation that did not show if the posture is safe from MSD risks. However, MSD risks can be reduced.

Abstract
Every company in doing business expansion, especially business outside the core business of the previous business field, generally requires sufficient funding sources to ensure that the expansion goes as expected. Funding according to the needs is often a pretty difficult problem especially when faced with choices that have a significant cost impact. In this study we address the problem faced by a cement company in Indonesia that has extra capacity and potentially can be used to produce other products under a joint venture scheme. The company is faced with 3 choices of funding sources to support expansion into the building materials business, one of which was to sell a certain proportion of shares of the capacity of 8 factories that were not absorbed by the domestic sales target in Indonesia to strategic partners. This study attempt to find the most optimal capacity allocation of all factories in meeting the domestic sales volume target by considering the minimal transportation costs using the linear programming method and compare the remaining plant capacity with the magnitude of the converted plant capacity. The results are expected to support funding proposals to realize the vision of entering the building materials business in Indonesia.

Published: March 2021

Abstract
In this paper, the problem to be solved is a feasibility study for waste utilization facilities development, especially for spent bleaching by considering the market, technical, and economic aspects. The amount of spent bleaching produced by the palm oil industry in Indonesia reaches 750000 tons/year. Government regulation number 101 2014 categorized spent bleaching earth as hazardous waste with a code B 413. Therefore, the companies must carry out environmental protection and management for spent bleaching earth. This facility built to capture the market of spent bleaching earth waste disposal service, raw material substitution, and alternative fuel (coal). From the market perspective, the facility will capture about 7% market shares. Based on the technical aspect, the calcination process, kiln operational, and quality of clinker won’t be disrupted if the capacity of waste facilities is 7-8 tons per hour. Based on the Payback Period calculation, it needs 5.4 years to return the investment. From the Net Present Value and Internal Rate of Return, it can be concluded that the development of waste utilization facility for spent bleaching is feasible. Based on sensitivity analysis the facilities must run above 60% capacity to make sure the facilities still feasible. Further research is expected to analyze the potential for other B3 waste which can managed by the facility and potential to enter end to end waste management business so it can have a greater impact to the company and society.

Abstract
In the Philippines, the Civil Registry Documents (CRD) acquired from Philippine Statistics Authority (PSA) such as Birth Certificate, Marriage Certificate, Certificate of No Marriage and Death Certificate are being used as one of the requirements in different transactions in academics, government, travel, employment, religious matters and other transactions (e.g. proof of identification, Title/Career advancement, etc.). The current acquisition ways of these Civil Registry Documents are through online, PSA Office, Travel Agency/Courier Company and Satellite/Mobile PSA Office. In this study, the different acquisition ways of Civil Registry Documents are analyzed through service blueprint. Furthermore, a survey was conducted to determine the satisfaction rate and preferences of the CRD acquirers and was analyzed through crosstabulations. With the help of the analyzed Service Blueprints, the possible problems that arises on each process of acquisition were identified. This paper proposed an instant, electronic (involves bar coding/QR code/Reference number), paperless and less time-consuming substitute to the existing ways of acquiring Civil Registry Documents.

Published: March 2021

Abstract
Culture is the core element of an organization. Organizational culture must reflect the shared values and beliefs that show people meaning and provide them the guidance to working behaviour. The organizational culture should be constructed by following the expected future values and considering the common value of people in the organization. Organizational Culture Assessment Instrument (OCAI) is one of the structural approaches to evaluate the implementation of organizational culture. Nowadays, many of the public university in Indonesia has been transforming into a more productive and agile organization. The university transformation also needs redefine or evaluate their organization’s values as a part of strategic plan. Applying OCAI framework is necessary to assess the excellence of the transformation process in university. OCAI has applied in our university, i.e.: Sepuluh Nopember Institute of Technology (ITS), to define the organizational culture for the higher agility of the organization in the future. More than 400 university employees, including lecturers and administration staffs, have involved in organization culture’s survey. The results of OCAI assessment showed that ITS tend to perform as the clan and the hierarchy type of organizational culture. While the management capabilities of ITS leaders showed that, the leadership characteristic is related to the clan culture.

Published: March 2021

Abstract
Roads have significant impacts on the environment, economy and society, and the choice of pavement thus has broad implications. All phases of road development, from construction to operations, consume a vast amount of resources and produce waste and emissions. This study aims to examine energy consumption and greenhouse gas (GHG) emissions of a road construction project using Life Cycle Assessment (LCA) approach. Semarang-Bawen section road project was used as a case study, which uses Asphalt Concrete-Wearing Course (AC-WC) and Asphalt Concrete-Binder Course (AC-BC) layers for flexible pavement, and concrete slabs for rigid pavement. The methods used to estimate energy consumption and GHG emissions refers to the Intergovernmental Panel on Climate Change (IPCC) procedure, i.e. the Energy Use and GHG Emissions for Pavement Construction, and Fuel Conversion Method. The results show energy consumption of the project for the flexible and rigid pavements are 1193.79 GJ and 952.056 GJ, respectively. This indicates that the flexible pavement contributes to CO2 emissions greater than the rigid one. The flexible pavement has a total emission of 89257.96 kgCO2/km, while the rigid pavement is of 70464.53 kgCO2/km. Based on these results it can be concluded that rigid pavement is considered more environmentally friendly than flexible pavement.

Published: March 2021

Abstract
In this research, a non-reinforced epoxy and its composites which reinforced by fiber glass, polypropylene fiber and micro-silica oxide powder, with volume fraction (20%) were prepared, using a hand lay-up molding method. Impact strength, Surface hardness, and Bending strength tests were carried out for the specimens before and after immersion in tap water and ethanol. Before immersion, the results showed that adding fiber glass and polypropylene fiber to the polymer improved the mechanical properties while silica particles decreased it. On the other hand water absorption of the substance led to a negative effect on the mechanical properties of the composite material. The effect of ethanol was the highest.

Abstract
We report the synthesis of CuO nanostructures on silicon(Si) and porous silicon (PS) substrate using hydrothermal method as seed layer and different reaction time (12 and 24) hour respectively. structure and sensing properties analysis of these nanostructures were studied using X-ray diffraction (XRD), (AFM) and FE-SEM analysis. all the obtained peaks in the XRD pattern are well matched with the monoclinic phase of CuO thin film prepared on silicon and pours silicon substrate with crystal sizes (25.2 to 11.6) nm and (21 to 9.9) nm for CuO/Si and CuO/PS respectively. Topography analysis studied by (AFM) and reveals that the grain size, roughness surface and root mean square of the prepared thin film decreases with the increase in the hydrothermal reaction time in both cases CuO / Si and CuO / PS. FESEM analysis, showed the morphological of film prepared at seed layer as seed-like structure, and change to nanosheets structure with increasing reaction time. EDX analysis revealed the chemical composition and elemental state of CuO nanoparticles. Gas sensor performance showed that thin films have good sensitivity properties but thin films deposited on porous substrates are better and amount to about 186%.
