Abstract

Concrete has become one of the most important building materials for the real estate and civil construction industry. This study aims to create new innovations in the world of constructions namely by utilizing materials available in nature namely beach sand as fine aggregate with the addition of Sikacim Concrete Additive to concrete mix. In addition, this study is intended to determine what if beach sand is used as fine aggregate and Sikacim Concrete Additive as an additive to the shear strength value of concrete. With variations of BTN, BTPP (30%, 50%, 70%), and BTPP (30%, 50%, 70%) + Sikacim Concrete Additive (0,8%) by weight of cement. The samples used were beams with dimensions of (60 cm x 15 cm x 15 cm) with a total of 21 specimens. Shear strength testing can be done if the concrete is 28 days old. The shear strength value obtained of BTN is 1,08 MPa, BTPP 30% is 0,91 MPa, BTPP 50% is 0,78 MPa, BTPP 70% is 0,73 MPa, BTPPS 30% is 1,21 MPa, BTPPS 50% is 1,04 MPa, dan BTPPS 70% is 0,96 MPa. The optimum shear strength value was obtained at the BTPPS 30%.

Abstract

ABSTRACT Jratunseluna river area is 9,576.01 km² wide crossing 10 regencies and 2 cities, one of which is Grobogan Regency. The River System in Jratunseluna river area consists of 4 systems: Semarang Barat, Dolok-Panggaron, Jragung-Tuntang, and Serang Lusi Juana (Seluna). There are 2 (two) main riversi in the Seluna River system: Lusi and Serang Rivers, both of which cross Blora, Grobogan, Kudus, and Demak Regencies. The research was conducted in Lusi Rivershed (DAS) in Klaten Hamlet, Ngaringan Village, Ngawen Sub District, Grobogan Regency. This research aims to find out physical condition of Lusi River, inundation height, total discharge, and inundation area on the existing cross-section of Lusi River and to find out safety factor in strengthening Lusi River slope. River gydrolic analysis was conducted based in direct procedure with software HEC-RAS version 5.0 help and the method used in the analysis was slope stability with Bishop’s wedge method. The result of field survey shows that river bank damage occurs in Lusi Rivershed due to flood, erosion, and condition of land proning to landslide in the riverbed. Meanwhile, the result of analysis using HEC RAS 5.0 with plan discharge Q 10 years shows inundatio heigh of 1.10 m, and total discharge/ total Q of 450.34 m³/s, and for the inundation area of 1478.35 m² and safety factor value in strengthening Lusi River slope using gabions in Klaten Village, Ngaringan, Wirosari, Grobogan, Central Java, the value of 1.2787 was found without gabions, 1.3115 with gabions, and 1.3800 for alternative gabion 3. Keywords: River, flood and landslide managemen

Abstract

Berbagai bahan alternatif diuji guna menghasilkan beton yang bermutu tinggi dengan material yang lebih ekonomis. Pada penelitian ini dilakukan pengujian dengan bahan alternatif ramah lingkungan menggunakan limbah plastik berjenis LDPE sebagai bahan tambah dalam campuran beton. Penelitian ini bertujuan untuk mengetahui karakteristik kuat tekan beton dengan bahan  tambah plastik tersebut. Dalam penelitian ini akan dibuat benda uji silinder dengan variasi komposisi penambahan limbah plastik LDPE 0%, 2,5%, dan 7,5% dari proporsi semen dengan jumlah sampel yang diuji sebanyak 9 buah Dari penelitian yang sudah dilakukan diperoleh hasil sebagai berikut, pada variasi 1 dengan penambahan 0% plastik memperoleh nilai kuat tekan tertingi 29,82 MPa, variasi kedua dengan penambahan limbah plastik 2,5% memperoleh hasil kuat tekan tertinggi 25,86 Mpa sedangkan untuk variasi 7,5% penambahan limbah plastik memperoleh hasil tertinggi 20,94 Mpa. Hal ini menunjukan bahwa semakin besar penambahan limbah plastik maka semakin menurun nilai kualitas beton nya. Dalam penelitian ini beton tidak memenuhi syarat karena kuat tekan rata-rata diperoleh kurang dari kuat tekan rencana.

Abstract

Sediment is material or fragments of rocks, minerals and organic materials that are carried away and move in the direction of river water flow. Sediment can be divided into base load (bead load) and suspended load. The bottom load moves in a rolling, sliding and jumping manner over the surface of the river bed. In optimizing river function, it is necessary to construct sediment control buildings to reduce sedimentation that occurs along the river. This research aims to determine the volume of open and closed type sediment storage and to compare open and closed type sediment storage. The methods that will be used in this research to determine the volume of sediment are stream flow, flow characteristics (Froude and Reynolds numbers) and sediment volume. The results of the research will show how large the sediment storage volume is for the two forms of sediment storage, for the closed type sediment storage the sediment storage volume is = 0.004898 m³. greater than the volume of open sediment storage (slit), namely (V) = 0.004683 m³ and for the comparison of open and closed sediment storage, the most effective in holding sediment is the closed type sediment storage which has a capacity = 93.1% greater than the storage volume open type (slit) = 72.1%.

Abstract

Pada asesmen bangunan gedung dengan struktur utama beton bertulang, tentunya penentuan kuat tekan beton menjadi faktor utama dalam keakuratan hasil analisis. Uji kuat tekan pada beton inti adalah yang paling akurat, namun pada asesmen struktur gedung eksisting umumnya dibatasi karena faktor operasional gedung, sehingga harus dikombinasi dengan uji tidak merusak (non-destructive test, NDT). Pada gedung tua umumnya proses karbonasi sudah terjadi, dan ketika karbonasi sudah mencapai tulangan baja, akan menginisiasi korosi dan ini menjadi patologis utama pada beton bertulang. Penelitian dilakukan untuk mengetahui kuat tekan beton pada gedung sekolah 3 lantai yang berusia lebih dari 30 tahun, dengan mengambil 10 sampel beton inti yang dibarengi dengan NDT yaitu uji karbonasi, pengukuran cepat rambat gelombang ultrasonik (UPVT) dan palu pantul beton. Dan 30 titik uji lainnya tanpa sampling beton inti. Hasil penelitian menunjukkan kedalaman karbonasi justru meningkatkan kuat tekan dan mengurangi tingkat kesalahan dalam estimasi, dengan:  dan =0,9241.

Abstract

In Aceh Tamiang Regency, Aceh province, various soil characteristics are observed. Expansive clay soil in Bukit Sabun Hamlet, Bandung Jaya Village, Manyak Payed District, Aceh Tamiang Regency, exhibits poor quality, leading to concerns such as cracks, subsidence, and shifting in buildings constructed on this land. The research aims to assess alterations in the physical and mechanical properties of expansive clay soil after incorporating palm oil tankos ash and sugarcane bagasse ash. The analysis is conducted according to the AASHTO (American Association of State Highway and Transportation) classification system. Test results indicate a decrease in water content during the Atterberg limit test. For instance, the Liquid Limit (LL) value of the original soil at 55.55% decreases to 54.89% when mixed with 25% bagasse ash and palm oil ash. Similarly, the Plasticity Index (PI) value reduces from 33.05% to 13.23% after mixing with the same ash combination. Standard proctor testing reveals that the 25% ash mixture yields optimal soil compaction results, indicating a potential breakthrough in enhancing soil stability.

Abstract

The signalized intersection is Jl. Basuki Rahmat-Jl. S. Maruni is an intersection that connects the city of Sorong with Aimas district, where since 2022 after the expansion of the Southwest Papua province it has encouraged the economy and population growth. Where facilities in the city of Sorong really need to be improved considering the increasing volume of vehicles. At the intersection of three with the signal Km. 10 The city of Sorong needs to review its performance, both the geometric conditions of the intersection and the traffic lights that work at the intersection. This is due to the high volume of vehicles from year to year passing through this intersection, considering that the intersection is in the middle of the city The analytical method used is calculating intersection performance using the 1997 Indonesian Road Capacity Manual (MKJI). Based on the analysis results for calculating intersection performance for intersection conditions where the level of service at the intersection is at value E. after carrying out simulations of traffic lights and road widening At one arm of the intersection you can see the change in service level to C, due to the decrease in the delay value.
