Abstract

Due to a series of natural disasters in Indonesia, swift rehabilitation and reconstruction efforts are necessary to repair homes and facilities with earthquake-resistant buildings. In response to this need, the Ministry of Public Works and Housing has developed the Rumah Instan Sederhana Sehat (RISHA) construction, which can be built quickly and is claimed to be environmentally friendly. The RISHA method is expected to reduce carbon emissions generated from the construction process. The choice of building materials plays a crucial role in construction, as the production of these materials requires significant energy and generates carbon dioxide (CO2). Selecting environmentally friendly materials can reduce energy consumption and carbon emissions throughout the building's lifecycle. This study aims to calculate the carbon emissions generated from the construction of houses using the RISHA method. The calculation method uses coefficients from The Inventory of Carbon and Energy (ICE) at Bath University. The study results show that one unit of RISHA house produces a total carbon emission of 18,392.34 KgCO2, with reinforced concrete, lightweight bricks, and cement being the main contributors. Optimization was carried out by replacing the original wall material of lightweight bricks with concrete blocks and the original floor covering material of ceramics with wooden parquet. The result was a 5.49% reduction in carbon emissions, amounting to 17,382.15 KgCO2.

Abstract

Tanaman eceng gondok yang berkembang biak dengan cepat dapat mengganggu lalu lintas (transportasi) air, meningkatnya penguapan, dan hilangnya air melalui daun-daunnya. Selain itu, tanaman eceng gondok yang mati dan terjatuh ke dasar perairan akan berakibat dalam peningkatan percepatan pendangkalan perairan, dan berkurangnya nilai keindahan lingkungan perairan. Oleh karena itu, ada manfaat dari penggunaan eceng gondok, seperti sebagai bahan tambahan untuk campuran beton. Untuk melakukan pengujian laboratorium, ditambahkan eceng gondok yang sudah berbentuk butiran atau serbuk pada beton dalam jumlah nol, satu, lima, dan sepuluh persen. Uji kuat tekan beton dilakukan dengan mutu K-175 selama 7 hari, 21 hari, dan 28 hari. Hasilnya adalah 10,78 Mpa, 10,39 Mpa, 6,35 Mpa, dan 1,92 Mpa pada hari ke-7, sementara pada hari ke-21, nilainya adalah 13,56 Mpa, 12,51 Mpa, 6,54 Mpa, dan 3,08 Mpa. Pada hari ke-28, nilainya adalah 15,01 Mpa, 13,38 Mpa, 7,61 Mpa, dan 3,18 Mpa. Kadar serbuk eceng gondok menurunkan kekuatan tekan beton

Abstract

Pembangunan jalan terus berkembang seiring dengan tuntutan zaman, hal ini terjadi di kampus Unisnu Jepara yang kepadatan lalu lintasnya semakin meningkat seiring dengan bertambahnya jumlah mahasiswa setiap tahun. Akses jalan yang hanya tersedia satu, membuat lalu lintas bertabrakan. Kebutuhan jalan alternatif sangat diperlukan guna mengatasi kemacetan dan ketidak teraturan lalu lintas. Penulis mengevaluasi permasalahan tersebut dengan merencanakan perbandingan perkerasan jalan (kaku, lentur, paving), sebagai bahan pertimbangan. Dalam perbandingan perencanaan ini metode yang digunakan untuk perkerasan kaku dan lentur menggunakan Metode Direktorat Jenderal Bina Marga 2017 dan perkerasan paving menggunakan Metode Analisa Komponen 2002. Berdasarkan analisis yang telah dilakukan dengan pertumbuhan lalu lintas (i) 1% dan umur rencana 20 tahun diperoleh hasil pertama perkerasan kaku tebal pelat beton 175 mm (dapat diakses oleh truk), lapis pondasi atas (kelas A) 125 mm dan lapis pondasi bawah (kelas B) 160 mm. Kedua perkerasan lentur tebal lapis AC WC 40 mm, AC BC 60 mm, AC Base 80 mm dan LPA Kelas A 300 mm. Ketiga perkerasan paving tebal perkerasan paving 80 mm (dengan frekuensi terbatas pada pick up, truk dan bus), lapis pondasi awal 100 mm, lapis pondasi akhir 236 mm. Sedangkan berdasarkan rekapitulasi hasil analisa didapat biaya struktur perkerasan kaku senilai Rp 2.718.646.898, biaya struktur perkerasan Lentur senilai Rp 2.112.631.770 dan biaya struktur perkerasan Paving senilai Rp. 902.412.387. Sehingga dapat diketahui bahwa perkerasan paving blok lebih hemat, namun struktur perkerasan paving blok sangat tidak nyaman untuk kendaraan dengan kecepatan tinggi dan kendaraan berat.

Abstract

This study assesses the effectiveness of lime in stabilizing soil and focus on the prospects of using eggshell powder as an economic and environmentally friendly alternative to lime. To ascertain the impact of different degrees of eggshell powder, particular at 0.5 g, 1g, 1.5g and 2g equivalent to 0.5%, 1%, 1.5% and 2% the weight of the soil respectively; and to replace up to 50% of the lime within the stabilization handle. This study proves that all treated tests shown relatively better result than untreated soil, that must satisfactory to ensure the stabilization strategy. Without a doubt, when lime is substituted with 25% of eggshell powder in the concrete formulation where favorable strength characteristics were obtained, it established that this level of substitution may well be carried out feasibly in practical use. This ponder supports the sensible treatment of accumulating eggshell powder to advance soil compactness and recommends discovering more deliberately wakeful development rehearses through utilizing waste products. The research finds reveal ways in which cost can be reduced and the soil natural appearance lost with traditional methods of soil stabilization can be minimized.

Abstract

The modulus of elasticity or modulus of stiffness is a metric that indicates the stiffness of a mixture based on the stress and strain relationship. One very important component that influences the performance of asphalt pavement is the stiffness modulus. A lower stiffness modulus value makes it easier to experience deformation, which causes the pavement to crack easily when subjected to heavy loads. Asphalt concrete mixtures with high stiffness modulus values ​​will be stiffer and more resistant to deflection. This study is experimental with the aim of obtaining an asphalt concrete mixture that is able to withstand loads without changes. In this study, the asphalt concrete mixture was composited with coconut fibers with the aim of determining the effect of coconut fibers in increasing stress and tensile strain as well as the stiffness modulus of the mixture. This type of test is carried out using an ITS test equipment to obtain stress, strain and stiffness modulus values.

Abstract

Soft soil is caused by cohesion, a low internal friction angle and high compressibility. If not recognized and investigated it can cause instability and long-term decline that cannot be tolerated. One of the treatments that occurs in soft soil is light backfilling with foam mortar. The aim of this research is to carry out an analysis of the stability of embankments using lightweight materials at the location of bridge embankments in order to predict how much of an impact there will be in reducing settlement and increasing embankment stability. Analysis was carried out using the Finite Element Method with the help of the Plaxis 2D program. The method used in this research is descriptive qualitative, namely research by collecting primary and secondary data from the parameters and variables studied and then analyzing them to draw conclusions. In the results of the analysis using Plaxis Softwere using foam mortar treatment with an embankment slope of 1: 1.5, the results showed that the decline in 1 year was 4 cm (meeting the design criteria), the decline in 10 years was 2.8 cm (meeting the design criteria), apart from that the safety factor using foam mortar was also greater than the design criteria, which means the stability of the slope is safe.

Abstract

Stabilisasi tanah merupakan salah satu upaya dalam memperbaiki karakteristik tanah ekspansif dengan menambah bahan pozzolan untuk meningkatkan kekuatan mekanis tanah. Penelitian ini bertujuan untuk megetahui keefektifan tipe semen Portland Composite Cement (PCC) dan semen mortar dalam meningkatkan kekuatan mekanis tanah ekspansif menggunakan uji Unconfined Compression Test (UCT). Pengujian UCT dilakukan dengan prosentase semen PCC dan semen mortar 0%, 4%, 8% dan 12%. Hasil pengujian karakteristik tanah asli menunjukan nilai berat jenis (Gs) 2,595, (LL) 58,54% dan (IP) 24,85%. Tanah asli dikategorikan sebagai tanah ekspansif karena memiliki nilai LL dan indeks plastisitas yang tinggi (PI > 20). Berdasarkan hasil pengujian UCT dengan bahan stabilisasi menunjukan bahwa semen mortar lebih efektif digunakan untuk meningkatkan kekuatan mekanis tanah (qu dan Cu) dibandingkan semen PCC pada prosentase paling optimum 8%. Sedangkan penambahan prosentase semen PCC dan semen mortar sebesar 12% menyebabkan nilai qu dan Cu menurun. Semen mortar lebih efektif dibandingkan dengan semen PCC dikarenakan semen mortar mengandung bahan tambahan pasir halus serta material aktif seperti silika dan aluminia, kandungan tersebut dapat meningkatkan reaksi hidrasi dan pozzolanik yang mengurangi plastisitas tanah ekspansif dan meningkatkan karakteristik mekanisnya.
