Abstract

Indonesia is the largest nickel producer in the world. but from another aspect, the problem of ex-mining pits, combustion ash waste, nickel slag and others are environmental issues in the nickel mining industry (nikel.co.id, 2020). Currently, the Ministry of Industry through the research and development unit is trying to raise the potential of nickel slag or slag so that it can be used as industrial raw material that is in line with environmental management in the context of a sustainable economic program (antaranews.com, 2020). Based of this study was conducted on the use of nickel slag as a substitute for coarse aggregate in concrete. This research is an experimental study with the objectives of analyzing the physical and mechanical characteristics of nickel slag, analyzing the compressive strength of concrete using nickel slag as a substitute for coarse aggregate, and analyzing the optimal percentage of nickel slag used as a substitute for coarse aggregate. The results of this study indicate that the use of nickel slag as a substitute for coarse aggregate for 20 MPa concrete, and unable to achieve the planned average compressive strength of 20 MPa plus a margin of 12 MPa, resulted in a decrease in compressive strength and did not provide quality improvement. concrete. The application of nickel slag as a substitute for coarse aggregate in structural concrete with a design compressive strength ≥ 20 MPa is not recommended.

Abstract

The objectives of this study are to analyze the characteristics of existing parking and analyze the need for parking spaces, parking characteristics were obtained at the Al Alam Mosque in Kendari City, namely the highest parking volume of 345 units of motorcycles and 374 units of cars, a motorbike parking capacity of 1394 units and a car of 666 vehicles, with a parking index of 90.82% for motorcycles and 191.74% for cars. Meanwhile, the need for parking space with two methods is obtained in a ratio of 1.5-3.5 parking space units (SRP) / 100 m² of land area, then a minimum of 190.38 SRP for LV 2nd class standards, or equivalent to 2379.75 m². By the method, the largest difference between the arrival and departure of the vehicle is the largest accumulation of a given time, obtained then it takes 1266 out of the 1410 SRP available. Meanwhile, for cars, 1277 SRP from the 666 available SRP or equivalent to 7,637.5 m² are needed.

Abstract

Masalah di Kabupaten Kepulauan Taliabu adalah mahalnya biaya konstruksi, banyaknya kegagalan konstruksi yang mana material yang digunakan merupakan material utama yang ada di Kabupaten Pulau Taliabu (BPS, 2020). Oleh karena itu, dilakukan penelitian karakteristik beton menggunakan Agregat Sungai Bobong dan Agregat Sungai Gela di Kabupaten Pulau Taliabu Provinsi Maluku Utara. Studi ini merupakan penelitian eksperimental dengan tujuan untuk mengetahui karakteristik agregat dari Sungai Bobong dan agregat dari Sungai Gela, serta kuat tekan beton yang dihasilkan. Dari penelitian diperoleh karakteristik agregat ex. Sungai Gela lebih baik dari pada agregat ex. Sungai Bobong, terlihat pada berat jenis pasir Sungai Gela lebih tinggi dari pada berat jenis pasir Sungai Bobong yaitu 2,63 gram/cm³ berbanding 2,50 gram/cm³. Demikian pula keausan agregat kasar ex Sungai Gela sebesar 13,48% lebih baik dari keausan agregat kasar ex Sungai Bobong yaitu 44,22%. Dari hasil penelitian didapatkan bahwa kuat tekan rata-rata yang diperoleh menunjukkan bahwa kuat tekan beton dengan agregat Sungai Bobong lebih baik dari pada kuat tekan beton dengan agregat ex Sungai Gela.

Abstract

Evaluasi Saluran Drainase Di Lingkungan Desa Tumbudadio adalah salah satu Desa Di Kecamatan Tirawuta Kabupaten Kolaka Timur yang tak luput dari masalah banjir yang banyak menyebabkan banyak kerusakan. Permasalahan yang terjadi pada desa tersebut yaitu setiap tahunnya selalu tergenang air khususnya pada musim penghujan. Untuk perencanaan pengendalian banjir, pengamanan sungai, dan berbagai bangunan air perlu dilakukan analisis hidrologi untuk mendapatkan besaran banjir rencana. Penulisan tugas akhir ini bertujuan untuk memperoleh besaran banjir rencana dan juga memperoleh kapasitas saluran drainase. Dalam penelitian ini menggunakan metode distribusi normal, log normal, log person III, dan gumbel. Hasil evaluasi debit saluran dengan debit rencana saluran drainase periode ulang 5 tahun diperoleh untuk saluran drainase dengan Qp rencana 1,30 m3/det dan Qmax saluran drainase adalah 0,105 m3.det, sehingga drainase tersebut tidak dapat lagi menampung air hujan dengan baik sehingga dapat menimbulkan banjir di kawasan tersebut.
