Abstract

In construction problem soils are often encountered, as well as in the border area of North Kalimantan Province, there are problematic soils such as peat soil and expansive soil. Problematic soils have low bearing capacity and high compressibility, therefore it is necessary to make improvements in problematic soils. One of the soil improvements whose application is quite easy and relatively inexpensive to implement is stabilization. This research uses coal waste material (fly ash) as a stabilizer from PLTU Sekayan in Apung village, Kaltara Province. The purpose of this study was to obtain changes in the CBR parameters on peat soil and expansive soil by mixing fly ash with variations in the addition of fly ash by 20%, 40%, and 60%, and through curing for 20, 30, 40, and 60 days. The analysis is presented in graphical form by comparing the original soil that has not been stabilized and the soil that has been stabilized with fly ash. From this research, it was found that the addition of a stabilizing agent in the form of fly ash can increase the CBR value in problematic soils. In the expansive soil CBR test in the laboratory, there was a very large increase in the CBR value, namely from the initial condition of 2,65% to 33.7% with the addition of 60% fly ash and a curing period of 60 days. On peat soil, the initial CBR value was 0,79% to 9.8% with the addition of 60% fly ash and a curing period of 60 days.

Abstract

The difficulty of obtaining embankment material as a road foundation is one of the problems in the construction of road infrastructure. Furthermore, soil with a low bearing capacity value can damage the road structure. Soil improvement with local soil stabilization is an effective solution to reduce construction costs in the procurement of embankment material. However, the soil quality in an area varies and does not always meet the requirements of the embankment material. From this, it can be concluded that there is need for soil improvement, one of which is soil stabilization with polymer. In this study, Cisasawi soil material was mixed with synthetic polymer polyacrylamide (PAM) in concentrations ranging from 0,2%, 0,4%, 0,6%, 0,8%, and 1%, and then atterberg limits and CBR laboratory were determined. At the end,  an observations was made to the effect of adding PAM for plasticity and bearing capacity of soil. The results of the tests show that adding PAM to the original soil can reduce the plasticity value by 22,27% and increase the bearing capacity by 21,0% and 29,2% in unsoaked and soaked condition. According to the findings of this study, the role of PAM can increase the bearing capacity of the original soil, causing the soil to become embankment material.

Abstract

Sampah menjadi masalah yang serius bagi semua negara di dunia, termasuk Indonesia. berdasarkan data BPS tahun 2021 jumlah sampah plastik di Indonesia mencapai 66 Juta ton per tahun, jumlah sampah terbesar kedua adalah plastik sebesar 15,7%. Untuk mereduksi jumlah sampah plastik recycle merupakan salah satu solusinya. Penggunaan sampah plastik sebagai bahan campuran atau sebagai bahan dasar pembuatan paving block adalah salah satu cara pemanfaatan  ulang sampah plastik. Permasalahan dalam penelitian ini adalah bagaimana pengaruh campuran antara plastik PET dan LDPE sebagai bahan dasar ditinjau dari kuat tekannya dan  apakah paving block dengan campuran plastik PET dan Plastik LDPE dapat masuk standar mutu yang dipersyaratkan menurut SNI 03-0691-1996. Metoda yang digunakan dalam pembuatan paving block dengan bahan dasar sampah plastik PET dan LDPE adalah metode eksperimental dan benda uji yang digunakan dalam penelitian ini sebanyak 54 buah dengan variasi campuran PET dibanding LDPE: 100:0%; 90:10%; 80: 20%; 70: 30%; 60:40%; 50:50%. Setiap variasi terdiri dari 3 benda uji, setiap benda uji dilakukan pengujian pada hari ke 7, 14, 28. Dari hasil pengujian diketahui bahwa paving block dengan bahan dasar sampah plastik PET dan LDPE berdasarkan kuat tekannya sesuai dengan SNI 03-0691-1996 dengan nilai kuat tekan rata-rata paling besar berada pada komposisi campuran sampah plastik PET 50% dan 50% sampah plastik LDPE sebesar 26,22 MPa dengan masa perawatan benda uji selama 28 hari dengan kualitas mutu B (kuat tekan rata-rata 20 MPa).

Abstract

Survey and mapping work can basically be done by various methods. Like terrestrial, photogrammetric and extraterrestrial methods, which generally have the same goal of projecting the earth surface into a topographic map at a certain scale. In this study, an exploration was carried out regarding the collaboration between the terrestrial method and photogrammetry in the depiction of topographic maps, which would provide more representative results. The object of this research is the land belonging to the PCNU of Tarakan City, which will be built as a school, where this land has a fairly steep surface relief. This study also provides comparison results from the application of the two measurement methods, which are applied to extreme land. Based on the analysis carried out, several research results were obtained, namely: The average percentage of the X,Y and Z coordinate of the two methods was 12,71% where a significant difference occurred in the altitude or Z component, which was 38,12% while the coordinate component X and Y have a difference value of 0,00%. The shape of the depiction of the soil relief produces an image that is close to the real condition, this can be seen from the contour shape that follows the shape of the soil relief on the sand cliff and tends to be random. The method that is suitable for use in the case of the object of this research is the photogrammetric method, because the steep terrain and irregular soil relief make it difficult to apply the terrestrial method, besides that the terrestrial method with the application of sampling point coordinates is not accurate to produce relief of the ground surface conditions actually.

Abstract

Tarakan is home to the main seaport that serves all districts in North Kalimantan. Tana Tidung Regency is one of the regencies that serve the Tarakan feeder port route. This is supported by the presence of a Sesayap River network. To provide comfort to service users, the high demand for ferry transportation services must be balanced with adequate speedboat service facilities. Data was collected by distributing questionnaires and conducting interviews to determine the level of satisfaction of service users and the attributes that are a priority in improving the performance of speedboat services. The data collection results were analyzed using Importance Performance Analysis (IPA) dan Customer Satisfaction Index (CSI) methods. Then, to follow up on the results of the IPA dan CSI analysis, the Quality Function Deployment (QFD) method was used, a technique used to identify priorities for performance management based on the needs and desires of service users. Based on the results of the IPA analysis, three attributes were obtained as the top priority to require handling/improving their performance; the availability of fire extinguishers, the availability of information on speedboat travel disturbances, and the availability of boarding and alighting facilities for passengers with special needs, children, and pregnant women. The result of the CSI analysis obtained a service user satisfaction index of 63.379 which indicated that the service performance perceived by service users was decreased within the “Quite Satisfied” criteria. While the results of the QFD analysis obtained a priority sequence for improving/handling speedboat performance which was offloading the passengers by being carried out or stretchered, and access was categorized as the first priority, the second and third priorities were the availability of communication tools that were readily used by the captain and crew in the speedboat and notifications in the form of messanges to prospective passengers related to changes in departure schedules, and the last priority was the placement of APARs at 3 points, which was near from the diver or captain, passenger room, and the speedboat engine area.

Abstract

Tarakan City, which is connected to Tanjung Selor by a speedboat, is one of the cities with access to maritime transportation. One form of improving speedboat services is by reviewing fares according to the ability and willingness to pay of the people. This study’s objective was to determine the fare by taking passengers willingness and ability to pay into account. The research’s methodology is based on analyses of vehicle operational costs (BOK), ability to pay (ATP), and willingness to pay (WTP). The research result, average values for the BOK, ATP, and WTP were IDR 182.386,96, IDR 165.128,25, and IDR 126.735,00, respectively. According to the ATP and WTP values, passengers had a higher ability to pay than they were willing to spend. Therefore, it is necessary to analyze the current pricing and improve the services.
