Abstract

Currently, there are many programs from the government related to urban villages. One of them is Kampung Kota Baru Tengah in Balikpapan City, which is the location for the Community-Based Settlement Environmental Management program (KOTAKU Program). The socialization program is carried out with an approach to the informal community. Socialization through community media is the mainstay of the government so that existing programs can be realized properly in society. This study aims to see the similarity of perceptions regarding space as a place to live. Considering that a common perception is one of the first steps to achieving the success of the KOTAKU program, where a common perception of where to live will become the vision of development in residential areas so that people will be more consistent in implementing the KOTAKU program. This study uses Multidimensional Scaling (MDS) analysis, which will then map the perceptions of settlements. The results of the perception mapping formed show that individuals in each community have different perceptions of settlements. Based on perceptions of reconciliation grouping, we found that 51% chose identity as the main reason for staying and 48.5% chose location dependence as the main reason for staying. This perception formed in the community suggests that government strategies for environmental and housing improvement programs are advocated to reflect or strengthen people's sense of identity and place dependability. Strengthening this sense of identity can be linked to any development activity that can reflect local wisdom, while the location dependency aspect can be linked to improving settlement infrastructure.

Abstract

The Manggar Final Processing Site (TPA) is a TPA located in the city of Balikpapan by implementing a sanitary landfill system. In this system, the waste is piled up into a mountain so that leachate generated from the waste will enter the layers below the surface due to rainwater. To detect the presence or distribution of leachate below the surface, an investigation was carried out using the Self Potential (SP) Method. The results of the data processing obtained are isopotential maps. From this map, we can see the distribution of leachate based on the potential difference value. Based on the slicing data from the anomaly, the value of the potential difference between 31 mV and -50 mV is found, which is scattered towards the north. This can be indicated as a leachate anomaly.

Abstract

This study designed a geophone prototype using a piezoelectric sensor based on Arduino Uno. This research aims to create an alternative tool from the geophone that can measure vibrations on the ground. To find out if the geophone sensor that has been designed can work well, namely by knowing how far away the sensor can receive a given vibration source. Geophone design made using a piezoelectric sensor based on Arduino Uno R3. The components used to make the prototype will be connected to the Arduino, with the output as a byte value converted into a voltage. These results were obtained from testing by taking data using a vibration source, namely a dropped load. The testing process is carried out by dropping the vibration source from a height of 55 cm with variations in the distance as far as 20 cm, 30 cm, 50 cm and 60 cm. From the experiments carried out, the prototype made can function to read data from the dropped source. The farther the vibration source is dropped, the smaller the voltage generated. The results obtained from this study are the design of a geophone prototype made on a laboratory scale.

Abstract

The  high carbohydrate content  in  durian seed flour  (DSF) has the potential to be a source of food energy that can replace wheat flour in the world. DSF processing has an impact on color changes that affect  the quality of the product.  Therefore, the purpose of this study is to modify durian seeds to obtain the best properties of durian seed flour through the soaking process. The modification was carried out  in a 0.6%  (w/v)  solution of sodium metabisulfite at a temperature of 30 ºC with a drying  temperature of 50 ºC for 17 hours before grinding and sifting in a size of 80 mesh.   Treatment of immersion time variables in minutes (40, 60, 80, 100, 120) using the Complete Randomized Design (RAL) method with three attempts.  The flour is then being analyzed its physical  and chemical properties.  The best treatment was obtained at soaking time during 120 minutes which had an impact on changes in chemical and physical properties.  The test  results showed that the longer soaking time reduced the moisture content and ash content of durian seed flour, but partially improved the  other parameters tested.  The amount of DSA, DSM  and fat is less affected by soaking time. In conclusion, DSF has the potential to be used as a base for pastries or biscuits due to its low water and protein content.  In addition, based on the residual content of sulfite, the durian seed flour obtained in this study is safe for consumption in accordance with GSFA standards.

Abstract

This study examines the distribution of Peak Ground Acceleration (PGA) in the Ibu Kota Nusantara (IKN) development area, Sepaku Sub-District, East Kalimantan, an area with relatively low seismic activity compared to other parts of Indonesia. However, earthquake risks remain a concern due to the planned relocation of Indonesia's capital. Using the Kanai approach and seismic data from microtremor measurements and two significant earthquakes (Paser Regency, 2022, and Palu, 2018), PGA values ranged from 0.69 gal to 34.29 gal. The results show that the 4.5 magnitude Paser earthquake produced PGA values between 0.69 and 3.17 gal (average 1.8 gal), placing most areas in the low-risk zone. In contrast, the distant 7.2 magnitude Palu earthquake generated PGA values between 2.9 and 34.29 gal (average 15.6 gal), placing several areas in the moderate-risk zone. These findings underscore the significant impact of earthquake magnitude on PGA, with larger, more distant earthquakes causing stronger ground shaking. In conclusion, despite East Kalimantan's low local seismic activity, the study highlights the vulnerability of the IKN area to strong ground shaking from distant, high-magnitude earthquakes. This underscores the need for continued monitoring and preparedness, with tailored earthquake risk mitigation strategies, including reinforced construction standards and geotechnical assessments, to ensure the region's resilience to both local and distant seismic events. These insights are crucial for integrating seismic resilience into IKN's urban planning and the sustainable development of Indonesia's new capital city.

Abstract

Institut Teknologi Kalimantan (ITK) is one of the state universities that is currently actively developing educational facilities and infrastructure. Geologically, ITK is built on the Kampung Baru sedimentary rock formation, which has a low level of soil bearing capacity. This can cause damage to the building if the determination of the foundation depth does not have the right bearing data. The study aimed to determine the subsurface structure in the ITK campus area based on the speed of seismic wave propagation and to determine the distribution of subsurface hard rock layers in the ITK campus development area. The research methods used are field surveys, data acquisition, seismic wave recording data, travel time curves, 2D fast wave propagation models, and interpretation. The research results obtained the value of the first layer wave propagation velocity on tracks 1,2,3,4, and 5, ranging from 128.7 - 201.9 m/s. The second layer on tracks 1,2,3,4, and 5 ranged from 272.4 - 428.0 m/s. The research concludes that it can determine the subsurface structure based on the fast wave propagation value, geological conditions, and outcrop findings, namely the first layer in the form of soil and the second layer in the form of sand clay. Development can be carried out in the passive clay layer by laying the foundation

Abstract

Identified subsurface composition remains one of the important things in development, such as finds out potential that is below the surface, this research in Institut Teknologi Kalimantan Campus (ITK). This study aims to identify distribute potential values and finds out the source of anomalies in the ITK Campus area. This study uses the Self-Potential method with a fixed-base technique. The data obtained in the form of potential difference (delta V) data, base potential data and measurement point coordinates. The data was corrected by daily base variation, daily correction and reference correction. After obtaining a potential value from the correction at each measurement point, the data processing was done using surfer 11 software. The results of data processing were obtained isopotential contour map and qualitative interpretation which could be seen distribution of potential different values. On the isopotential contour map, slicing of two cross sections selected indicates the source of anomaly. Anomalous potential values of 45 mV to -55 mV indicated anomalous sources namely electrolyte potential in groundwater with positive anomaly values negative up to hundreds of mV. And, there was a potential for a liquid flowwith a positive and negative anomaly ≤ 100 mV

Abstract

Microtremor analysis has been done in the Sepaku Sub-District as a part of the New Capital City of Indonesia. This study aims to determine the characteristics of microtremors in the Sepaku Sub-District using Spectrum Analysis and Time-Frequency Analysis (TFA). Data in this study were taken using a seismometer on the 18 measurement points. The data were processed using default analysis from Geopsy software. Spectrum analysis and TFA used Fourier Transform to change time domain data into the frequency domain. Both analysis ways result in the characteristic microtremor data in the research area. The spectrum analysis data obtained shows two frequency ranges with maximum peaks: middle-frequency (5-8.8 Hz) and high-frequency (11.5-17.6 Hz). Afterward, the TFA shows similar results, where the characteristics of microtremor data are divided into two zones. The maximum peak occurs at the middle-frequency range of 5-10 Hz, and the high frequency ranges above 10 Hz

Abstract

Sinabung Volcano is located in the Karo Highlands, Karo Regency, North Sumatra, Indonesia, with a peak of 2460 meters above sea level. This volcano experienced an increase in volcanic activity in the April-October 2021 period, so it is necessary to analyse volcanic seismicity to determine the hypocenter distribution of the volcano. This study aims to determine the hypocenter distribution and classification of volcanic earthquake types based on seismogram recording data of Sinabung Volcano at four stations, namely LKW, BGR, MDD and SGR stations. The method used in this research is Geiger's method with adaptive damping (GAD) to determine the distribution of hypocenters. The results showed that the hypocenter distribution gathered below the crater centre with depths from 0.172 km to 7.139 km. The determination of the hypocenter distribution of volcanic earthquakes is expected to provide information on the depth of the earthquake to determine the movement of magma and the characteristics of events that occur during the pre-eruption process of Sinabung Volcano so that this data can be used for mitigation decision making when there is an increase in the activity of Sinabung Volcano.
