Abstract

The increasing numbers of people and buildings that continue to grow and tend to be uncontrolled in the settlement causing some negative impacts one of them is the consistency of land allotment. This has resulted in some impacts such as ineffective utilities and environmental infrastructures, no mitigation system, and the unavailability of space for public spaces and other supporting facilities that supposed to be available within a settlement. Kampung Arab is one of a densely populated settlements located in the middle of business center area of Manado City, occupies the Mahakam riverbank. The limited space available in Kampung Arab has caused the settlements tend to be slummed and doesn’t have public open space as one of the residential support facilities. In addition, this settlement expands riverbanks so the functions of riverbanks become disturbed, and these settlements are often at risk of flooding. The purpose of this research is to analyze the function of Mahakam riverbanks against flood risk and to analyze the possibility of public space and pedestrian ways availability at the location of Mahakam riverbanks around the Kampung Arab settlement. The research method is qualitative descriptive method. Primary data were obtained through field observation, documentation, and interviews. The research is located in Kampung Arab settlement which occupies the banks of Mahakam River. Further analysis is done: 1) analysis of existing settlement of Kampung Arab to the Mahakam River related to: building’s orientation, river border, activity and behavior of society 2] analysis of public open space availability and its former elements, 3] analysis of settlement utility system and at the final stage conducted an analysis related to community activities and behavior. Expected results through this research are: improving function and quality of Mahakam River, restoring the function of riverbanks and public open space availability as social interaction space.

Abstract

The developments that occur in Manado city, have an impact on changes in existing urban ecosystems and land use. Mapanget sub-district is an area adjacent to the suburbs, when viewed from the ecosystem typology of the land use with plantations, but due to developments in the city center, land changes and land use in the Mapanget district have changed the typology of existing urban ecosystems. The purpose of this study was to analyze land changes and land use in Mapanget sub-district in order to determine the typology of urban ecosystems. The method used is descriptive. To be able to analyze land changes and land use Arc Gis 10.3 software was used with supporting data, namely the 2002-2018 satellite imagery map, 2007-2016 land use map. Based on the results of the analysis, the changes in land use from 2002 was 86.95% reduced to 74.26%. Built land in 2002 was increased from 13.05% to 25.74%. The use of residential lands significantly increases from a land area of 394.09 ha to 733.05 ha. Research shows that the typology of urban ecosystems in Mapanget sub-district consists of absorption typology for around 1395.62 Ha (26.96%), composite ecosystems for approximately 40.54 Ha (0.78%), and production ecosystems around 3740.67 Ha (72.26%). Hence, the typology of production ecosystems is the most dominant changes in land use and more directed to the ecosystem typology of absorption, while land accretion is built at 25.74%.

Abstract

A 7.4 magnitude earthquake have strucked Donggala on September 28th 2018, followed by tsunami and liquefaction which hit Palu, Central Sulawesi, a few minutes later. This event had resulted in damage to buildings, and caused more than 2,000 people were killed and injured. Indonesia already have a building code in form of SNI 1726:2002 which had been updated to SNI 1726:2012. This paper analyses the hazard level caused by the 2018 Donggala earthquake compared to the existing design spectra, as mentioned in SNI 1726:2002 and SNI 1726:2012. A simple analysis was carried out by comparing Donggala earthquake’s acceleration response spectra with the existing design spectra, at the MPSI accelerograph station. The site class at MPSI station is hard soil (SC). The seismic hazard in Palu and Donggala refers to SNI 1726:2002 is included in the earthquake area 4. The maximum earthquake response factor for earthquake area 4 is about 0.6 for hard soil type (SC). The MPSI station recorded peak ground acceleration of Donggala earthquake around 0.14 g. The acceleration response spectra recorded at the MPSI station showed a peak value of around 0.71 g for the N component. This value is actually still below the design spectra referring to SNI 1726:2012, which the peak value is 0.88 g for SC, but, it exceeded the design spectra of SNI 1726:2002.

Abstract

Land use change occurs in many cities in Indonesia. Population growth causes the expansion of residential area. Without proper planning and design, the development of residential area can increase the runoff volume. The objective of this study is to provide an eco-drainage system design for real estate in Indonesia to minimize the possible increased runoff.The study area in this paper is a bare area of 14,602.26 m2 in Mojokerto Regency, East Java, Indonesia which is planned to be developed into real estate. The design of eco-drainage system consists of installation of 4400 litre of rainwater storage tank and a 1200 m3 of retention pond. The analysis includes the estimation of peak discharge of the selected area using the Rational formula and estimation of evapotranspiration in the retention pond using Thornthwaite method. The result of the analysis shows that 50.2 m2 of roof surface can capture rainwater varies from 0.04 – 18.4 m3/month. The water is used to fulfil the household water needs in the real estate such as for sanitation & waste disposal, gardening, personal washing, cleaning home, and washing clothes along the year except in August and September. While overflow of the tank occurs in January, February, and March. The excess rainfall, which is not captured, flows to the retention pond. It is used for watering public garden using a sprinkling water system. The combination of chosen dimension of storage tank and retention pond can reduce the runoff volume minimum by 48.19% in February in the study area.The proposed design still cannot accommodate all excess rainfall due to the transformation of a bare land into real estate. Therefore, it is recommended to consider another utilization of water in the retention pond.

Abstract

The existing drainage system of roads proposed to manage the quantity of runoff from the road only, while the quality remains uncontrolled. In fact the pollutants and waste originated from the road surface contains hazardous substances. Sustainable drainage system (SUDS) concept offers various structures to solve both quantity and quality problems of surface runoff from roads. One of the potential drainage structure is filter drain or infiltration trench develope along the right side and left side of road. It could be developed by retrofitting the existing drainage channel of the road. The objective of this paper proposes the design model of road drainage based on the concept of a sustainable urban drainage system. The model consists of U-ditch channel, reservoir, an infiltration well. The bottom of U-ditch channel completed with a number of holes to make it porous. The channel filled with aggregate to filter the runoff from the road before flow down into the reservoir beneath. The water is then discharged to infiltration well. The model was developed based on rainfall data and other physical characteristics in Ambarawa City, Semarang Regency, Central Java.The channel dimensions and the depth of aggregate filter were designed base on runoff volume. The relationship among rainfall, runoff volume, area ratio, and drainage dimension are obtained. The results concept of sustainable road drainage is obtained in addressing the quality and quantity of rainwater.

Abstract

The problem of waste is very worrying because it has a direct impact on humans, especially the inclusion of plastic elements in the human body through fish and food exposed to microplastic. One way to overcome the problem of waste is to reduce waste from its source by sorting methods from the source and managed further through the process of recycling or upcycling into new products. Reducing waste from its source by sorting and then saving it in a Waste Bank is one promising breakthrough and can encourage people to actively participate in environmental management. The purpose of this study was to obtain a mapping model of the waste management service area in the city of Manado as needed. The research data was obtained through research on smash applications for waste banks supporting field research through observation and interviews. Data was analyzed by mapping the position of waste banks in the city of Manado. Furthermore, comparing the three garbage banks in Manado city to find a pattern of waste bank management with various indicators. The results of the study indicate that the current mapping of the position of waste banks in Manado consists of the center, the suburbs and outside the city. Furthermore, the results of the comparison of the three garbage banks conclude that the most effective waste bank is a waste bank in a residential area. An effective waste bank is one of the strategies for implementing 3R (Reuse, Reduce, Recycle) in waste management at its source at the community level. The implementation of the waste bank in principle is a social engineering to invite the public to sort out waste for environmental sustainability and public welfare.

Abstract

The Coast Area is an area that has a physical condition where erosion occurs at other times, sedimentation occurs. Both of these conditions can be a problem in coastal areas. This is very closely related to land use in coastal areas. Another problem is that in protecting the beach by the government it is very expensive and cannot be carried out simultaneously throughout the coastal areas, so that people have to wait in uncertain times.In North Sulawesi coastal areas are widely used as settlements, tourist areas and other public facilities. The community has its own ability both in terms of the availability of natural resources and labour, so that it can secure the coast to reduce the risk of damage in its coastal areas.The method of building of non-structural coastal protection can be carried out by people whose construction types can be combined according to the conditions and availability of natural resources in the area.

Abstract

Sedimentation has been an issue for a long periode of time. It affects the river morphology process which is constantly changing from time to time due to its sediment supply system. There are 2 main parameters that strongly affect the morphological process and those are discharge and sediment. When the movement of the sediment occur it will lead to degradation and agradation along the river that will affect the river morphology. Because of those processes, the river dynamic characteristic should be considered in structural design.In North Sulawesi, Tondano River has been known as one of the main river and it has a discharge all year around. With rapid land coverage change, dicharge may increase significantly and hence more sediment could be transported. Moreover, there are increase use of the river resources and more structures built along its sides that appeared to have induced more sediment in transport.This paper presented the corelation between discharge of various flow rates and the amount of sediment being transported at these rates along certain river segments. Slight changes on morphology of the river due to degradation and agradation processes at these segments were also displayed Analysis was carried out to evaluate agradation and degradation processes during various flow rate at the middle section of the Tondano River. Prior to this was the analysis of river discharge. This research has confirmed that indeed the sediment transport occurred at the observed river’s segments was due to the varied discharges. The transport therefore instigated the recurrent changes on the river’s morphology this may pose threats to the stability of river’s structures i.e. by means of scouring progression. Solutions suggested to overcome the problem includes: 1). Non-structural or structural reinforcement on the river bank; and 2). Sediment management to overcome the degradation and agradation processes.

Abstract

Winds, tides and river discharges largely drive coastal currents. The strength of tidal currents, river runoff, meteorological conditions, shoreline configuration, water depth and topography are the factors that affect coastal water circulation. Generally currents are the flowing of water mass caused by wind, difference of density or tide moving. The existence of currents direction to nearshore of Amurang Bay was studied with using computer model tools as the hydrodynamic model by determine currents speed and its direction.The study took place in Amurang Bay as the province of North Sulawesi Indonesia with the geography position around 1012’16.16” N-124027’04.33” E to 1015’43.80” N-124032’01.06”E. The bathymetry and tide data used in this research from Indonesian Coastline Environmental map of year 1995 with scale 1:50.000 from BIG (Badan Informasi Geospasial) with a satellite data from Google earth of year 2018 and LANTAMAL Manado, the wind and current data was obtained from BMKG Bitung. Time simulations are taken from 25 November to 23 December 2016 as a wet season and 25 Mei to 23 Juni 2016 as a dry season. As analytical tools, MIKE3 hydrodynamic mode are used. The currents pattern play an important role in sediment transport process, so the study of the currents pattern become to be important as well. The result of this study indicate that in the wet season the combination of tide wind in surface and bottom layer of sea the currents direction close to nearshore dominant to East with current speed average 0.18 m/s, in dry season the combination of tide wind in surface layer of sea the currents direction close to nearshore dominant to South-East with current speed 0.12-0.24 m/s, in bottom layer the currents direction dominant to South-East with current speed average 0.2 m/s. Some of interesting point in research’s area show that current by tide make the current direction seaward and landward, but tide combination wind change the direction of current. It can be said that the tide influenced to current make the currents direction seaward and landward follow the pattern of tide, but combination tide and wind change its direction.

Abstract

The data for this research is compiled from the records of hourly rainfall between 1993 to 2014 which was generated from several. Automatic Rainfall Stations namely; Ayong-Bumbung Climatology Station, Sangkub-Huntuk climatology station, and Sangkub-Pangkusa Climatology Station. The data was then analyzed using statistical methods. Rainfall distribution pattern is based on heavy rainfall recorded by automatic rainfall measuring device. The rainfall data used here are the ones with rainfall depth of more than 50mm. All the data are then analyzed to obtain the frequency of occurrence of each of the rainfall duration. From the result of frequency analysis, it is then determined that certain rainfall duration represents the general rainfall condition in the research area. Research will show that rainfall pattern on the Northern Coast of Bolaang Mongondow, for heavy storm have a tendency of 7 hour duration, with 22% distribution for the first hour, 28% distribution for the second hour, 19% distribution for the third hour, 15% for the fourth hour, 7% for the fifth hour, 6% for the sixth hour, and 3% for the seventh hour.
