Abstract

Penataran train decreased the number of passengers by 77.13% in April 2020, which resulted in a reduction in travel frequency and change origin-destination during the COVID-19 pandemic. This study aims to determine the characteristics of the Penataran train passengers and obtain policy recommendations about service standards and travel requirements based on respondents' choices using descriptive statistics. Questionnaires were distributed to 417 Penataran train passengers during new adaptation period. This study indicates that the frequency of trips during the new adaptation period is lower than before the pandemic. Only 10.55% of respondents give the reason that the risk of transmitting COVID-19 on the Penataran train is lower than other transportation. The maximum seating capacity is reduced to 50% according to respondent's perceptions. Wearing a mask, keep a distance, and wearing long-sleeved clothing can still be carried out because they are considered necessary as requirements for passenger travel. The GeNose C19 test letter is not recommended to be used as a document requirement because most respondents with low income do not want additional costs.

Abstract

Swamp area is usually seen at the debouchment that is close to the sea. Swamp area can be used for farming area if it has a proper water management system. However, water management at the swamp area is hard to do and can be potentially become over drained in some areas. The aim of this study is to locate the potential areas that are able to occur over drained at Petung Swamp Irrigation System and able to find solutions of the problems. The first step to do is doing survey to know the condition of the channel, finding hydrological data, and tidal data. The hydrological data are intended to get modulus drain discharge. The next step is running data with HecRAS application to get the result of water channel profile of all channels. After that, analyzing the groundwater level could be done and meet the conclusion whether the channel is having over drained or not. The result of this study is the areas of Petung Swamp Irrigation that mostly having over drained condition are at the headwaters because the tide cannot reach the upper areas. The areas also have no floodgates, so the water journey couldn’t be occurred and not evenly distributed.

Abstract

Bindu River Ecotourism is a tourist attraction that has natural potential as a place of recreation in the Denpasar City area. Apart from the potential offered by Bindu River Ecotourism, there are still problems that exist in Bindu River Ecotourism including river water which has a lot of sediment, the lack of public awareness to care about the surrounding environment, and the lack of exposure by the public makes only the surrounding community aware of it. If zoning is not carried out in its development, the natural potential of the Bindu River Ecotourism area that has been arranged can be reduced, for this reason, zoning is needed in its development to determine areas in the Bindu River Ecotourism area that are in accordance with the land use and development potential. Based on the delineation and the existing potential, the Bindu River Ecotourism area is divided into a conservation zone and a recreation zone. For the conservation zone, it can be developed into several more zones in the upstream part, it can be developed into a zone for the development of the function of protecting water resources, a zone for the development of the function of protecting flora and fauna as well as limited recreational functions. While the recreation zone can also be developed into several more zones. The upstream recreation zone can be developed into a recreation function development zone and the downstream recreation zone can be developed into an educational function development zone.

Abstract

This study aims to examine the sediment distribution models and the stream sediment distribution due to mud disposal of Porong River. It examines how the sediment distribution models and deposition, the distribution of stream sediment due to mud disposal along with its impacts on the river's capacity, and whether the mud disposal has a harmful impact on the water quality. The data used were based on topographic and Bathymetric data of Porong River, cross-sections of the river, and terrain sediment distribution patterns. The study conducted field and secondary data analysis, hydrological analysis, oceanographic analysis of Mura River and river hydraulic analysis. The study concludes that to maintain its capacity and prevent negative impacts, it is necessary to protect the cliffs and embankments along the segment of the river. To protect the community pond area, overburden and/or river dredging activities along with the segments from the branch to the estuary of the river are needed. Furthermore, it is also necessary to add artificial inputs such as submersible Kribs that are arranged on piles to deal with problems of river sediments in the mouth of Porong River.

Abstract

Ayunan Village, is located in Abiansemal sub-district, Badung regency, Bali. Bali cattle are germplasm that must be preserved, for that we are collaborating with the Bali Karang Ayu and Karya laksana cattle groups in Ayunan village. The maintenance of Bali cattle in partners is very constrained by capital, feed and management of Balinese cattle maintenance is not carried out professionally because it is managed in a family, traditional way and is not a main source of livelihood. Bali cattle maintenance is only a sideline to fill spare time on the sidelines of farming time. The management of cow dung and manure has not been managed properly, which should still be managed into organic fertilizer, sold to farmers so that it can increase the income of farmers, so the solution we offer is to provide assistance and consultation as well as demonstration plots regarding good and correct management of Balinese cattle rearing. to increase Bali cattle production. The results of this community service activity can increase production, productivity as well as produce organic fertilizer from cow dung that can be sold so as to increase the income of Balinese cattle farmers in the two Bali cattle groups that we partner with.

Abstract

Water is a basic need for humans, yet often the quality and quantity become cronstrained as happened in Mojoagung District, Jombang Regency. During the dry season, the potential for water reserves available for use is rainwater that has been stored. Based on laboratory tests, the quality of the stored rainwater is below the quality standard due to its high KMnO4 (Calium Permanganate) content. Hence we need a simple filter to improve the water quality. Researchers have conducted experiments with the filter composition of zeolite, activated charcoal, activated sand, sterile cotton, and aquarium filter. The results of the filtration process showed a significant decrease in potassium permanganate. The filtration results from the filter with the composition of zeolite, activated charcoal, activated sand, sterile cotton, and an aquarium filter sequentially 5 cm, 10 cm, 15 cm, 4 cm, and 2 cm succeeded in reducing potassium permanganate levels from 11.73 to an average of 2.12 mg. /l. The best filter due to experimental activities will be integrated with rainwater harvesting structure system which has been discussed along with related social community and stakeholders.

Abstract

This paper focuses on analyzing the bearing capacity of large diameter drilled shafts that are fully embedded in the claystone and sandstone layers. The foundations used are the drilled shafts for the Pulau Balang bridge pylons built across the Balikpapan bay. Three bored pile foundations with a planned diameter of 2 meters by 60 meters were used. The bearing capacity of the foundation in the field was carried out using the Osterberg cell test. The bearing capacity of the upper side of the foundation is 32.77, 27.26, and 114.46 MN, and the lower parts are 26.98, 27.16, and 50.25 MN, respectively. The results show that the method closest to the upper part of the OC test is the method suggested by Kulhawy and Phoon, with a value of C = 0.5. As for the lower part, the closest approach is the combination of the Kulhawy and Phoon and the Rowe and Armitage methods. The combinations of methods that approximate the total bearing capacity of the field are the Kulhawy and Phoon (1993) and Rowe and Armitage (1987) methods for the dominant claystone layer, and the O'Neil and Reese (1993) and Rowe and Armitage (1987) methods for the main sandstone layer.

Abstract

Park and Ride (P&R) is a form of transportation demand management closely related to commuting activities. Several developed countries, such as the UK, Canada, China, and Hong Kong already implemented P&R with a high level of effectiveness and success in overcoming the congestion problems in the city center, low use of public transportation, and air pollution. However, in developing countries, the various positive impacts of P&R still have not been able to encourage commuters' intentions to use these facilities. The level of P&R use at Sidoarjo Station is still relatively low (44.3%). Behavioral is one of several keys to the success of P&R that depends on intention and ability. The intention is the result of knowledge, social, and infrastructure that can support the use of public transport and P&R. This study aims to identify factors that can influence commuters' intentions to use P&R at Sidoarjo Station based on the theory of planned behavior using SEM analysis. The results showed that P&R and public transportation conditions as perceived behavioral control were the most influential factors on commuter intentions. The conditions of public transportation (including availability and location) and the quality of P&R facilities are also essential considerations for commuters using P&R.

Abstract

The increasing demand for energy causes the depletion of fuel fossil. To overcome this, it is necessary to utilize biomass and biomass waste. The purpose of this study was to simulate the effect of bio-pellet density on temperature, rate and pressure of combustion made from a mixture of gelam wood and rice husk. The method uses ANSYS simulation with literature review. The results showed that the increasing composition of rice husks had an effect on the decreasing combustion rate, this was due to the calorific value of the pellets making up the material. Where the lower calorific value of rice husk has an effect on the rate of combustion. Pellets that have a large density affect the rate of combustion so that it extends the burning time. The density of pellets is influenced by the pressure of pellet molding, the greater the pressure makes the fuel denser and has a large density. The highest combustion air pressure occurs at 100% gelam composition and the lowest at 100% husk composition. This shows that the addition of rice husk composition reduces the combustion pressure and vice versa applies to the addition of gelam composition.
