Abstract
This study aims to determine the application of regulations related to work safety equipment and its availability on purse seine vessels in the Ocean Fisheries Port (PPS) of Kutaraja, Banda Aceh, and to find out fishermen's perceptions of the importance of work safety equipment. This research was conducted in July 2018, using the method of direct surveys and interviews concerning existing national regulations. Data were analyzed descriptively and linear regression analysis through SPSS program. The results showed that from all samples of vessels 11 GT-> 61 GT (n = 21) the percentage of the presence or application of safety devices on purse seine vessels was 63%. In the 11 GT - 20 GT category the existence or application of safety equipment is 45% (n = 3), on the 21 GT - 30 GT vessel is 60% (n = 6), on the 30 GT - 50 GT ship is 65% (n = 7), on vessels 51 GT - 60 GT is 57% (n = 3) and on vessels larger than 61 GT is 86% (n = 2). In general, fishermen already understand the importance of work safety equipment, but the availability and number of occupational safety equipment on the ship are inadequate. Safety tools (independent) work influences the perception of fishermen (dependent) of only 1.83%, the rest of 98.17% is influenced by other factors outside the availability of work safety tools.

Abstract
We investigated the sediment conditions on the Leupung Beach, located in Aceh Besar District, Aceh Province. Sampling was carried out in November 2018 at 3 stations along the coastline. Sediment sampling was carried out in the swash zone area by dividing each station into two zones, namely upper swash zone (USZ) and lower swash zone (LSZ). Sediment samples were taken vertically using a modified coring pipe to a depth of 15 cm. Sediment stratification was done by dividing the sample into 3 layers, where each layer has a thickness of 5 cm. The results obtained are sediment in the USZ area in the form of fine sand; moderately sorted to moderately well-sorted; symmetrical to coarse skewed; mesokurtic to very leptokurtic, while LSZ in the form of fine sand; moderately sorted to moderately well-sorted; symmetrical to coarse skewed; platykurtic to leptokurtic. The difference in position between LSZ and USZ, relative to the water level, gives a difference in the grain size distribution between the two.

Published: November 2019

Abstract
The research was conducted to analyze the status of SES in coastal areas and small islands, and their implications for management planning of coastal areas and small islands. The study used the SES method approach. The dynamics of SES shows the interaction of the four main subsystems (resources, resource units, governance systems, and users), influenced by social, economic, and political settings, and their relevance to ecosystems. Each component of system status varies, and tends to be weak. All components of the system must be important variables in supporting the management planning of coastal areas and small islands in the Tanimbar Islands Regency. The management plan must be carried out through the arrangement of a social, economic and collaborative political system; optimize system management and resource units; developing adaptive governance systems; strengthen user capacity; the negative impact of some interactions of SES components is reduced collectively; and comprehensive measurement of social and ecological performance.

Abstract
The existence of vibrant public spaces is one of livable and sustainable city criteria. It is important to study how high-density areas in a city provide vibrant spaces such as good atmosphere for economic activities. The research took place in Gang Ampiun -- a tight alley of Kampong Cikini, a strategic and tightly-packed settlement in Central Jakarta. There, people tend to use the street area, as an attempt to fulfil spatial needs within a limited space. The aim of this study is to discover how the overlapping happen in slack space and the result of overlapping in shifting or create threshold and boundary. The research is conducted through interviews, mapping, photos, and note-taking for four days using qualitative analytics method. Several aspects were observed, including spatial arrangements of property for commercial purpose, as well as where the seller and buyer activity take place. This study reveals that the alley and gutter are seen as slack space due to the emergence of the private owned property for commercial use. Therefore, it affects accessibility and results in a new or shifting boundary.

Published: November 2019

Abstract
This study focuses on the monitoring of rusted and non-rusted rebar protected by sacrificial anode cathodic protection until 1000 days. Three specimens of RC beam structures having a length of 580 mm and 150x100 mm cross-section are fabricated. Two reinforcing barwith the same surface condition (ø 13 mm) were embedded in mortar parallel to each other with the intermediary distance of 40 mm and the cover depth of 30 mm in the bottom surface of the specimen. Discrete sacrificial zinc anode is connected to one rebar in patch repair section. During the investigation, the specimenswere exposed under three conditions, i.e., 20°C air curing, dry-wet cycle, and dry laboratory air. Potential of both rebar and sacrificial anode was monitored to check the condition of the cathodic protection system. The result indicates that non-rusted rebar condition in repaired patch concrete (chloride-free) is the most desirable initial condition when the sacrificial anode is applied on it to protect corroded steel bar in existing concrete (chloride contamination).

Published: November 2019

Abstract
Many construction practitioners in developed countries are already aware of reducing and managing construction waste. In Indonesia, it has not yet become a primary concern. Typically, the priority still focuses on how to win competitions instead and finish them on time with some profits. Whereas, the volume of waste in the world continues to grow day by day. The aim of this study is to explore best practices of construction waste management in developed countries to be implemented in Indonesia. The objectives are; (1) to examine the implementation of waste management in construction projects in developed countries and (2) to identify context, drivers and barriers of the construction waste management practices. A comprehensive literature review is conducted to address these aim and objectives. The results show that in general, many developed countries can reduce and manage their construction waste with supports from stakeholders, the availability of regulation with strong sanctions, law enforcement from the government, another supporting system, and high awareness from the practitioners. Although each country arguably may have best practices due to the local context, nevertheless these results may give insight and are useful for stakeholders in the Indonesia construction industry.

Published: November 2019

Abstract
This study presents a simple NDT method with Ultrasonic Pulse Velocity (UPV) to detect repair of R/C columns by injection and grouting. In this paper, the technique applied is mainly based on the use of epoxy under pressure into the R/C column crack system for lightly damage, whereas grouting used for repair of medium and heavy damaged R/C columns. The specimen is initially charged to increase axial loads up to 0.1P0, 0.3P0 and 0.5P0. After repair, all specimens were retested with the same method. The test results show that the repair technique is in a good category with a pulse velocity value of 4.21km/s. Pulse velocity transmitter analysis provides conceptual support to increase column capacity through repair methods. Direct methods can be recommended for post-repair structural strength with high accuracy. This method is a potential candidate for future development, especially to predict the level of damage and building rehabilitation after an earthquake.

Published: November 2019

Abstract
Bamboo is a natural material that can replace wood, but the bamboo weakness is easily attacked by powder beetle and a bad connection system. a simple method of bamboo connection system often uses fibbers, ropes or rattan. However, this method cannot guarantee the unity of structural elements, over time the bonds will become saggy because the shrinkage that is affected by temperature changes. Another alternative can be done by using the bolt or the Cendani bamboo (Bambusa multiplex) as shear connector. The purpose of research is to know the ability of the bolt and the Cendani bamboo the shear connector in an element structures of bamboo. The research method is done by combining three pieces of bamboo with mortar filler using the bolt and Cendani bamboo as a shear connector, then apply the load to the ultimate limit. The result showed that use of bolt as the shear connector was stronger than Cendani bamboo. This is available with the results of the higher tensile strength of the bolt compared by the tensile strength of Cendani bamboo.
Investigation of Tsunami Hydrodynamic Loads Acting on A Slab Bridge
Authors: Hartana  
Published: November 2019

Abstract
An analytical approach based on numerical simulation is performed to investigate the mechanism of a slab bridge damages caused by tsunami. This slab bridge was constructed in a parallel bridge structure with the adjacent highway bridge. Tohoku earthquake tsunami flooded and washed away this slab bridge. The CADMAS-Surf numerical model was used to determine the dynamic loads acting on the slab bridge subjected to a bore type tsunami. A series of hydraulic experiments were conducted, and the results were compared to the results obtained from numerical simulation. Numerical results showed good agreement with experimental ones in terms of water surface elevation, wave pressure and force. The validated numerical model was applied to the prototype scale of slab bridge that had 3D geometry. Simulation results showed that the tsunami flow fully overtopped the slab. The horizontal force was relatively smaller than the uplift force, however the total uplift force exceeded the dead load of the slab. This result meant that the tsunami flow uplifted the slab and washed the slab downstream. The effect of the existence of adjacent highway bridge on the characteristic of tsunami inundation and forces acting on the slab bridge is also discussed.

Abstract
Energy demand rises significantly correlated to human activities in recent years. In contrary, energy supply from unrenewable resource decreases gradually from year to year. OMW as one of the renewable resources has not been expanded well in Indonesia. Therefore, SMFC will answer the alternative technology to generate electricity from OMW. The objectives of this study are conducted to compare of waste volumes on power generation and COD removal in SMFC and determine the optimum waste volume for SMFC application affected by river sediment microorganism source and mixed waste type. SMFC reactor as MFC single chamber was designed by 2.5-liter volume of plastic houseware utilized with single graphene anode and cathode to increase the power generation.
The waste volume as the independent variable was adjusted 1/3; 1/2; 2/3 of the 2.5- liter volume of SMFC reactor, whereas river sediment microorganism source and mixed waste were dependent variables. The power density and COD removal percentage in 1/3VR, 1/2VR, and 2/3VR were compared on days 21 which was the typical day of the optimum performance of SMFC. The result shows that power density and COD removal of waste volume 2/3VR was higher than 1/3VR and 1/2VR. Power density of waste volume 2/3VR increased 1.5 - 3 times of power density of waste volume 1/3VR and 1/2VR, respectively. COD removal of waste volume 1/3, 1/2, and 2/3 remained stable. The optimum waste volume, the higher power density and COD removal, in addition to the result that 2/3 of the waste volume was the optimum result.
