Abstract

SWMM is a rain-runoff simulation model that is used to simulate the quantity and quality of runoff from urban areas. Based on the evaluation using SWMM software at Pesona Citra Cemerlang 2 Housing, it was found that the drainage system in the long sections JU29-O5, JU4-O8, and JU5-O8 could not accommodate rainwater runoff. This is influenced by the dimensions of the drainage channel which cannot accommodate the existing water runoff and thick sediment deposits that cover the drainage channel so that the capacity is reduced, consequently if it rains it will cause puddles of water at several points in Tarakan City. So to overcome the puddle, it is necessary to change the dimensions of the channel and routinely dredge the sediment deposits that cover the drainage channel

Abstract

Berdasarkan beberapa kelemahan yang dimiliki struktur flat plate, maka SNI 03- 1726-2012 membatasi penggunaan struktur jenis ini lebih spesifik, yaitu struktur diklasifikasikan sebagai SRPMM (Sistem Rangka Pemikul Momen Menengah) dan jika digunakan sebagai sistem tunggal, maka kategori desain gempa yang sesuai adalah B dan C tidak dibatasi dan D, E dan F tidak diijinkan, hal tersebut membuka peluang penerapan struktur ini pada daerah-daerah dengan gempa yang relatif minim, misalnya di hampir seluruh pulau kalimantan. Tujuan dari penelitian ini adalah mengetahui selisih penggunaan beton antara struktur pelat-balok dengan struktur flat plate dengan rongga 2 arah (BHS). Metode pelaksanaan penelitian adalah membandingkan volume beton struktur konvensional dengan BHS. Berdasarkan evaluasi hasil perbandingan diketahui bahwa terdapat selisih sebesar 26.0% lebih sedikit pemakaian beton struktur flat plate dengan rongga 2 arah (BHS) daripada struktur pelat-balok konvensional.

Abstract

SNI 1726 is an Indonesian code that regulates earthquake loads that will be imposed on a structure. SNI 1726-2002 never been updated for a long time until 2012 and was renewed again in 2019 to become SNI 1726:2019 due to changes in earthquake points that continue to occur. This study aims to analyze the Earthquake Response Spectrum using earthquake maps in SNI 1726 in 2002, 2012, and 2019, especially in Tarakan City. The earthquake response spectrum map from SNI 1726:2012 and SNI 1726:2019 was taken from the response spectra application published by the Ministry of Public Works and Housing. The results show that the building whose Response Spectrum Graph is SNI 1726 in 2002 is higher than SNI 1726 in 2012 but not bigger than SNI 1726:2019. So that buildings designed based on SNI 1726 in 2002 and 2012 must be studied more deeply in anticipating earthquake loads given SNI 1726:2019

Abstract

Changes in land cover caused by development activities carried out by humans have occurred a lot in Indonesia. It can cause a decrease in the carrying capacity of the environment. Therefore, this study aimed to assess the status of the environmental carrying capacity of the Tanjung Buka Village wetland, geographically located at 117°21'0" - 117°40'0" EL and 2°50'0" - 3°0'0" NL, where the land cover has changed many times due to development activities. The status assessment uses an ecosystem service approach with a simple, weighted approach to mathematical modeling, by using landscape, vegetation type, and land cover parameters. The results showed that: (1) The Tanjung Buka Village wetland ecosystem is dominated by the "very low" category (26,968.70 or 62.31%) of its ecosystem services as a provider of fresh water. It means its carrying capacity is "very low" in the fresh water supply, used continuously. At the same time, Food providers tend to be in the "high" category (20,917.47 ha or 48.33%), which means that in general, the carrying capacity of the Tanjung Buka Village wetland environment is "high" as a food provider that is used continuously. It indicated that the Tanjung Buka Village wetland had changed the land cover, becoming secondary mangroves, secondary swamp forests, ponds, open land, built-up land, mixed gardens, and shrubs, so that its carrying capacity becomes “very low” as a provider of fresh water, but in providing food tends to be “high”.

Abstract

Tana Tidung Regency as a new autonomous region in North Kalimantan in 2007 resulted in increased interactions between regions in support of the supply of food, and other social needs. Tarakan City is an essential region supporting the Tana Tidung Regency. Currently, public the primary transportation from the Tarakan-Tana Tidung is served by two modes of transportation; Ferry Boats and Wooden Boats. Researchers conducted a study to identify the trends and variables that affect the choice of Tarakan-Tana Tidung freight routes to enhance the performance of primary public transportation. Study used variable freight costs per coli, travel time, the timetable for departure, service convenience, and travel time to the Port of Tengkayu 1 or Juata Ferry Port adapted from the study of transportation mode selection by travelling persons. The survey, in the form of a questionnaire to 170 respondents, used the stated preference method and was conducted with multiple regression analysis to obtain the quantitative relationship between a collection of research variables and respondents to obtain utility and probability by modelling the binomial logit. The research results showed that the discrepancy between the Ferry Boats and Wooden Boats was in balance, with 65% of the patrons choosing the Wooden Boat to support the freight activities. All research variables have been influential in the choice of goods transport mode in the most dominant order, namely goods transportation cost per coli variables, travel time, the timetable for departure, service convenience, and travel time to port.

Abstract

Pasir halus bergradasi buruk diketahui rentan terhadap ketidakstabilan, keruntuhan dan likuifaksi. Oleh karena itu, perbaikan diperlukan untuk meningkatkan sifat pemadatan tanah. Studi ini berfokus pada peningkatan sifat pemadatan dan oleh karena itu kekuatan geser pasir bergradasi buruk. Pasir dicampur dengan lempung plastisitas tinggi 30% hingga 55% dan diuji karakteristik pemadatan dan kekuatan gesernya menggunakan Proctor standar dan peralatan tekan bebas. Hasil penelitian menunjukkan bahwa penambahan lempung 30% mengubah perilaku pasir gradasi buruk tak kohesi yang ditunjukkan dengan batas cair 48,08% dan indeks plastisitas (IP) = 11,29%. Plastisitas tanah meningkat dengan penambahan lempung hingga 55%. Uji Standard Proctor yang dilakukan pada campuran tanah menunjukkan penurunan berat isi kering maksimum (MDD) dan peningkatan kadar air optimum dengan penambahan lempung. Namun, hasil uji kuat tekan bebas menunjukkan peningkatan kohesi tak terdrainase dengan meningkatnya persentase lempung dalam campuran.

Abstract

Road construction on expansive soil faces many problems such as deflection, longitudinal cracks, circular cracks and spreading cracks in road construction due to the large nature of swelling and shrinkage. This study aims to identify changes in the mineralogy microstructure and chemical properties of the soil in chemically corrected expansive soils so that solutions for expansive soil improvement are obtained by utilizing local materials based on industrial waste, namely Fly ash and Waste Foundry Sand. The research method is in the form of laboratory experiments, namely Structure Electron Microscope and XRD tests on native soil and soil stabilized with Fly ash and Waste Foundry Sand to analyze mineral structure and chemical changes. The results of the analysis found that the effect of the two types of additives on expansive soils was descriptively significant. The addition of fly ash and WFS to the soil makes the pores and cracks filled with fly ash particles and some form of hydration. After the addition of Fly ash and WFS, ion exchange and pozzolanic reactions from fly ash occur to make the flake and flocculant structure of the soil cement into a crystal or block structure, thereby increasing the compactness and integrity of the soil sample.
