Abstract

This study aims to determine the availability of Tilong Reservoir inflow related to climate change. Water availability can be seen from the high inflow into the reservoir, obtained using the Mock model to simulate the inflow. The modeling results using the Mock model in the historical period are then compared with the results of future projections using GCM CanESM2 data from SSP119 to SSP585 scenarios. The historical period is modeled using rainfall from 2000 to 2019, while the projection period is divided into two periods, namely the 2030s (2020-2039) and 2050s (2040-2059). The projection results show that the highest increase in rainfall will occur in the SSP245 scenario for the 2030s and 2050s. The highest increase in future rainfall occurs in June, while the highest decrease occurs in August. With the increase in rainfall, there will also be an increase in inflow into the Tilong Reservoir, especially in December, which is more than 100% for each SSP scenario. In addition, an increase in water availability can also be seen by an increase in the dependable discharge, especially at SPP245, where there was an increase in the highest dependable discharge of 64.23% in the 2030s and 76.80 in the 2050s. The increase in dependable discharge is seen to positively impact the water availability of the Tilong Reservoir. However, it is necessary to pay attention to the reservoir’s operational pattern so that the existing water can be used optimally.

Abstract

Malaka Regency is one of the regencies that is often affected by floods every year. The losses caused by floods include, cutting off access to an area and damage to houses and furniture in the house, so that people have to evacuate to other areas or to higher ground. Incidents like this show that these houses have not been able to respond to floods that occur, including Fahiluka Village in Malaka Tengah District, Malaka Regency. The characteristic of Malaka Regency settlements is traditional houses in the form of stages with wooden walls and thatched roofs. Traditional stilt houses are also included in flood disaster response housing, but stilt houses have almost disappeared due to modern houses that are built directly in contact with the ground. This study aims to design a flood-responsive building model by utilizing modern building materials but still adhering to local wisdom. The results of the calculation and modeling of the flood that will occur with a return period of 25 years, obtained a maximum flood height of 2.5 meters. Building materials use reinforced concrete construction on the elements of the building structure and the shape of the building resembles a local building model and the function of the building space is adjusted to the needs of the community, the area of ​​the house designed is 54 m2. The design of the building with a stilt house model is expected to be one of the solutions in minimizing losses due to the overflow of the flood community that cannot be avoided in the Fahiluka village area.

Abstract

The Barito watershed, as one of the largest watersheds on the island of Kalimantan, has an upstream area that is close to the equator, while the downstream area is far from the equator. This makes it interesting to see climate variability, especially rainfall that occurs in the Barito watershed. The extreme rainfall indices R20mm and R50mm are used to see the spatial variability of rainfall events, while R1X and RX5 are used to see the temporal variability of rainfall that occurs in the Barito watershed. This research shows that the frequency of rainfall events from meteorological stations, PERSIANN satellites and GPM satellites occurs most frequently in the Upper Watershed area. However, rainfall trends have not shown significant results in the last 21 years between the upstream, middle and downstream watershed areas. This is influenced by the sloping and flat conditions of the watershed, resulting in rainfall intensity tending to occur evenly throughout the watershed. The results of the IDF analysis show that there are similarities between the rainfall intensity measured at the meteorological station and the PERSIANN satellite, which gives varying intensity values ​​over a short duration of less than 50 minutes.

Abstract

Rainwater Harvesting System (RWHS) is a simple concept for utilizing water resources, by collecting rainwater that falls in the roof and channeling it into a reservoir. Non domestic water needs in school buildings are needed in large quantities considering the large number of water users. With the RWHS concept, it is hoped that it can provide an alternative solution for using rainwater at SMA Negeri 1 Taebenu. Basen on the results of the water balance analysis at SMA Negeri 1 Taebenu, the water deficit was greatest in Juli at 0,61 liters/s. Based on these values, 2 rainwater storage tanks are planned with a capacity of 4,5 m3 each with dimensions of 1,5 x 1,5 x 2 meters. The storage tank is designed to be below groung level due to limited land. Rainwater is only used for bathroom purposes and watering plants, so the design of the reservoir is made simple, just using a dirt filter in the gutter to dispel dirt carried from the roof into the tank.

Abstract

Corrosion can be triggered by a chemical reaction to the materials, establishing reinforced concrete's failure. For a long time, researchers have tried to find out how to prevent corrosion, a main structural construction issue. As a technology of waste material, fly ash has predominance, i.e., it is safer and greener than Portland cement. The finer size of fly ash can be an advantage in filling the concrete materials well. This research is about using fly ash as supplementary material on reinforced concrete beams and the galvanostatic method to accelerate corrosion. This research will compare the shear strength after corrosion of each normal beam and fly ash as a supplementary beam. A shear test of fly ash and a normal reinforced beam has been applied. Results showed that fly ash beams have 14% higher compressive strength and 3% higher shear strength with 14% smaller crack width than normal beams after corrosion. It also has a 3,5 times lower rate and 62% level of corrosion than normal beam

Abstract

One type of ceiling often found in commercial buildings today is gypsum board. Slowly, the ceiling of the house made directly from wooden ribs and plywood began to decrease, and in general, local artisans in the Oetalu area, East Penfui, Kupang Regency, are not yet skilled in installing gypsum ceilings and do not even know how to do it. What often happens is that foreign artisans from Java or Sulawesi do gypsum ceiling work. This is a problems for empowering and developing local artisans' skills. In addition to the problems mentioned above, to become a professional artisan in construction, you must be certified by a certification body and the public works department. The qualifications of gypsum ceiling artisans are at class/level 3, and their classification is gypsum ceiling artisans with the number TA013. Ownership of a craftsman's competency certification is an obligation for construction workers as regulated in the Construction Services Law. After that, a training activity was carried out with lectures and practical training for three days, starting from purchasing materials, assembling steel frames, and installing gypsum boards, and ending with finishing. The results of this training activity are that the training participants, in this case, members of the local artisans group, are skilled in gypsum ceiling work and are ready to become gypsum ceiling workers, ready to take the craftsman certification test organized by the association or public works department. There was a significant increase in knowledge and skills among local artisans in gypsum ceiling installation work.

Abstract

This study aims to determine the availability of Tilong Reservoir inflow related to climate change. Water availability can be seen from the high inflow into the reservoir, obtained using the Mock model to simulate the inflow. The modeling results using the Mock model in the historical period are then compared with the results of future projections using GCM CanESM2 data from SSP119 to SSP585 scenarios. The historical period is modeled using rainfall from 2000 to 2019, while the projection period is divided into two periods, namely the 2030s (2020-2039) and 2050s (2040-2059). The projection results show that the highest increase in rainfall will occur in the SSP245 scenario for the 2030s and 2050s. The highest increase in future rainfall occurs in June, while the highest decrease occurs in August. With the increase in rainfall, there will also be an increase in inflow into the Tilong Reservoir, especially in December, which is more than 100% for each SSP scenario. In addition, an increase in water availability can also be seen by an increase in the dependable discharge, especially at SPP245, where there was an increase in the highest dependable discharge of 64.23% in the 2030s and 76.80 in the 2050s. The increase in dependable discharge is seen to positively impact the water availability of the Tilong Reservoir. However, it is necessary to pay attention to the reservoir’s operational pattern so that the existing water can be used optimally.

Abstract

The area of Ibu Kota Negara (IKN) in East Borneo is a strategic area that is projected as the new capital city of Indonesia therefore it requires water resources infrastructure to support development of IKN.  IDF curve analysis of the IKN watershed is expected to be able to estimate the amount of rainfall intensity with various return times to design various types of water structures such as drainage, culverts, and flood canals. Rainfall data in the form of daily data is a consideration for conducting IDF curve analysis using the Mononobe equation and the Sherman equation. The distribution of rainfall of the IKN watershed follows the Log-Normal distribution and produces design rainfall values with various return times such as 2, 5, and 10 years. The trend of rainfall intensity of the IKN watershed shows that rainfall intensity decreases as the duration of rainfall increases. The Sherman equation is known to give higher rainfall intensity values than the Mononobe equation at short durations of less than two hours while for durations of more than two hours, the opposite occurs. The maximum rainfall intensity is 419.67 mm/hour at a return period of 100 years at a duration of 5 minutes or 0.083 hours. The minimum intensity is found at a duration of 5 hours with a return period of 1.1 years amounting to 7.74 mm/hour. While the results of the analysis with the Sherman approach, with the same return period and duration, obtained a maximum value of 231.42 mm/hour and a minimum value of 10.88 mm/hour.
