Abstract

Fly ash atau abu terbang adalah limbah pembakaran batu bara yang membutuhkan area pembuangan atau penimbunan yang luas. Penimbunan abu terbang dalam jumlah yang banyak dan terus menerus akan menyebabkan terjadinya polusi yang merusak ekosistem di sekitarnya. Pencampuran abu terbang dengan semen Portland untuk membuat sejenis semen Portland Pozzolan dapat memberikan keuntungan ekologi dan membuat dan menghemat sumber daya alam. Penelitian ini menggunakan sejenis semen Portland Pozzolan yang mengandung abu terbang untuk membuat Self Compacting Concrete (SCC). Perbandingan air terhadap semen (W/C) merupakan suatu parameter yang penting dalam campuran beton. Mix desain dengan beberapa variasi (W/C) yaitu 30,35, 40% dibuat untuk mempelajari pengaruh W/C terhadap slump flow dan kuat tekan SCC.Kata kunci: semen Portland Pozzolan, Self Compacting Concrete (SCC), perbandingan air terhadap semen (W/C), slump flow, kuat tekanPermalink: http://www.ejournal.undip.ac.id/index.php/mkts/article/view/3940[How to cite: Tjaronge, M.W., Djamaluddin, A.R., Lemba, N.R. dan Kalesaran, I., 2006, Influence of Water to Cement Ratio (W/C) on Slump Flow and Compressive Strength of Self Compacting Concrete (SCC) Containting Portland Pozzolan Cement, Jurnal Media Komunikasi Teknik Sipil, Volume 14, Nomor 1, pp. 106-111]

Abstract

Handling of coal burning waste of thermal power plant in Lati, Berau district, East Kalimantan province, which is recommended by the department of environmental impact management is to dispose the coal ash into pools flowed water so that coal ash did not fly and cause air pollution. As known that coal ash waste is included hazardous and toxic waste, therefore managing it carefully is a necessity. Sediment or heap of coal ash in the sedimentation pond that is flowing with water is called Pond Ash. This study is conducted by utilizing the pond ash as a replacement material in the concrete mix. The effect of the use of pond ash as partial replacement of sand, fine aggregate in the concrete mix, is studied using cylindrical specimen with a diameter of 100 mm and a height of 200 mm. Specimens were made by taking the ratio of the percentage of pond ash of 0%, 5%, 10%, 15% and 20% of the mixture of concrete with the constant water cement ratio 0.49 which is based on the results of normal concrete mix design. The compressive strength test of concrete was conducted at ages 1, 3, 7, 14, 28 and 90 days. The test results of compressive strength of concrete obtained showed an increase in compressive strength in accordance with the addition of pond ash in the mix. The adding of pond ash in the mix affected the increasing in the compressive strength of concrete, and the optimum strength is obtained in the ratio of 17% pond ash, which increased to 26.08 MPa from 25.05 MPa for concrete with and without pond ash mixes respectively, or increased by 4.12%. This increase is not significant and cannot be used as a reference, however, by the results of this study it can be concluded that the pond ash waste can be utilized for the manufacture of concrete as a partial replacement of sand.

Abstract

Building Information Modelling (BIM) adalah sebuah pendekatan untuk desain bangunan, konstruksi, dan manajemen. Software Tekla merupakan revolusi baru dalam bidang rekayasa struktur yang memiliki beberapa keunggulan dibanding program aplikasi lainnya. Tekla Structures merupakan perangkat lunak Building Information Modelling (BIM) yang memungkinkan untuk membuat dan mengelola data secara akurat dan rinci, serta dapat membuat model struktur 3D tanpa melupakan material dan struktur yang kompleks. Penggunaan BIM di Indonesia masih hanya sebatas menjawab persoalan bagaimana mengefisiensikan kebutuhan tenaga kerja, waktu dan uang. Jika kita berkaca pada bagaimana pengaplikasian metode BIM di negara lain, potensi yang dicapai dari pengaplikasian metode BIM di Indonesia masih jauh dari kata maksimal. Tantangan selanjutnya adalah bagaimana mengenalkan teknologi aplikasi BIM ini dan mendorong penerapan BIM ini ke seluruh pihak stakeholder sektor konstruksi yang terkait. Maka dari itu, kegiatan pengabdian pada masyarakat ini bertujuan untuk memberikan pengenalan tentang Building Information Modelling dan memberikan keterampilan dasar dalam penggunaan aplikasi teknologi BIM dengan software Tekla Structures. Kegiatan ini dilaksanakan di Departemen Teknik Sipil, Universitas Hasanuddin yang dihadiri oleh 35 peserta yang berasal dari kalangan praktisi dan akademisi. Tahapan kegiatan pengabdian meliputi kegiatan sosialiasi ke stakeholder melalui mitra Lembaga Pengembangan Jasa Konstruksi Provinsi Sulawesi Selatan (LPJKP Sul-Sel), pengumpulan data berupa shop drawing, pembuatan modul, pemodelan dan laporan berupa quantity dan gambar kerja.

Abstract

The earthquake in Central Sulawesi in September 2018, accompanied by tsunami and liquefaction, caused very significant infrastructure damage, especially in Palu City. Roads are one of the vital infrastructures that have suffered a lot of damage. Efforts to rehabilitate roads due to the disaster have been carried out and have left quite a lot of old road pavement material. This dredging material needs to be optimized for use, especially in new pavements. Because this can make new materials efficient, especially aggregates in the pavement mixture. The use of new aggregates can be conditioned to a minimum by making efficient use of recycled materials. Namely by determining the type of pavement layer that best suits the gradation conditions of the recycled material. The purpose of this study was to obtain the type of flexible pavement layer that best suits the gradation of post-disaster recycled material based on standard specifications. The method used is sieving analysis of recycled material from several locations in Palu City that were affected by the disaster. The results showed that the use of post-disaster recycled materials, based on the recycled aggregate suitability value, was the AC-WC layer of 78.33%, the HRS-WC layer of 70%, the AC-BC layer of 66.67%, the layer of AC-Base is 41.67% and SMA-Thin layer is 40%. Based on the grading analysis, post-disaster recycled material in Palu City is most suitable for the AC-WC layer type because the addition of new aggregate is the least, resulting in the most optimal use of recycled material.Kata kunci: Recycled Material, Post Disaster Material, Flexible Pavement, Gradation

Abstract

Pemanfaatan material perkerasan jalan pasca bencana di Kota Palu dan penggunaan material lokal yaitu Asbuton Butir Lawele diharapkan dapat bersinergi dengan baik pada campuran Beton Aspal Lapis Aus (AC-WC). Tujuan dari penelitian ini adalah untuk menguji pengaruh penggunaan material daur ulang (RAP) dan asbuton butir terhadap sifat volumetrik campuran AC-WC. Bahan RAP yang digunakan dalam campuran adalah 20% dari berat campuran dan variasi asbuton yang digunakan adalah 0%, 3%, 6% dan 9% dari berat campuran. Berdasarkan hasil pengujian diketahui bahwa penambahan material RAP dan asbuton butir pada campuran AC-WC dapat mempengaruhi sifat volumetrik campuran. Nilai rongga dalam campuran (VIM) dan rongga dalam agregat mineral (VMA) akan meningkat seiring dengan peningkatan persentase asbuton. Sebaliknya, rongga yang terisi aspal (VFB) akan berkurang dengan bertambahnya jumlah asbuton. Sehingga dapat dikatakan bahwa campuran AC-WC yang mengandung RAP dengan penambahan asbuton butir, akan mengalami perubahan volumetrik jika dibandingkan dengan campuran tanpa RAP dan asbuton butir. ABSTRAK Utilization of post-disaster pavement materials in Palu City and Indonesian local materials, namely Asbuton Butir Lawele, are expected to synergize well in Asphaltic Concrete Wearing Course (AC-WC) mixture. This studio aims to examine the effect of recycled materials (RAP) and granular asbuton on the volumetric properties of the AC-WC mixture. The RAP material used in the mix is 20% of the mixture weight and variations of asbuton used are 0%, 3%, 6% and 9% of the mixture weight. Based on laboratory results, it was found that the addition of RAP material and granular asbuton to the AC-WC mixture could affect the volumetric properties of the mix. The value of voids in the mixture (VIM) and voids in mineral aggregates (VMA) will increase as the proportion of asbuton increases. On the other hand, the void filled with asphalt (VFB) will decrease with the increasing number of asbuton. So it can be said that the AC-WC mixture containing RAP with the addition of granular asbuton, will experience volumetric changes compared to the mix without RAP and granular asbuton.

Abstract

The penetration index (PI) of bitumen is one of the parameters to measure the temperature sensitivity of bitumen. The bitumen quality will decrease if the bitumen's resistance to temperature changes decreases. This evaluation was based on previous research that used recycled bitumen from the extraction process. Bitumen modification was done by adding different percentages of recycled bitumen to fresh bitumen. PI values were determined using the Pfeiffer and Van Doormall equation, which shows the relationship between penetration and bitumen softening point. Based on the analysis, it was found that adding recycled bitumen up to 30% can increase the PI of bitumen, but the PI of bitumen will decrease with the addition of RAP. Adding recycled bitumen can reduce the bitumen's resistance to temperature, so a rejuvenating agent is needed to restore the physical properties of bitumen containing a high percentage of recycled bitumen. ABSTRAK Indeks penetrasi (PI) bitumen merupakan salah satu parameter untuk mengukur sensitivitas bitumen terhadap temperatur. Sensitivitas bitumen terhadap temperatur dipengaruhi oleh perubahan viskoelastis bitumen. Kualitas bitumen akan menurun bila ketahanan bitumen terhadap perubahan temperatur juga menurun. Evaluasi ini didasarkan pada penelitian sebelumnya yang menggunakan bitumen daur ulang dari proses ekstraksi. Modifikasi bitumen dilakukan dengan menambahkan bitumen daur ulang dengan presentase yang berbeda pada fresh bitumen. Nilai PI ditentukan menggunakan persamaan Pfeiffer dan Van Doormall, yang menunjukkan hubungan antara nilai penetrasi dan nilai titik lembek bitumen. Berdasarkan hasil analisis diperoleh bahwa penambahan bitumen daur ulang hingga 30% dapat meningkatkan nilai PI bitumen, namun PI bitumen akan menurun seiring penambahan RAP. Berarti bahwa penambahan bitumen daur ulang dapat menurunkan ketahanan bitumen terhadap temperatur sehingga bahan peremaja diperlukan untuk mengembalikan sifat fisik bitumen yang mengandung bitumen daur ulang dengan persentase yang tinggi.

Abstract

Penelitian ini bertujuan untuk mengevaluasi kinerja mortar berkelanjutan yang menggunakan Screened Palm Oil Fuel Ash Passing Sieve No. 325 (S325-POFA) sebagai bahan substitusi sebagian semen. POFA diperoleh dari limbah pembakaran tandan kosong kelapa sawit dan disaring menggunakan saringan No. 325 untuk memperoleh fraksi halus. Variasi campuran dibuat dengan kadar substitusi 0%, 10% dan 20% terhadap berat semen. Uji laboratorium meliputi pengujian workability (flow table), kuat tekan pada umur 7 dan 28 hari, serta analisis estimasi emisi karbon berdasarkan kandungan material. Hasil menunjukkan bahwa penambahan S325-POFA hingga 20% dapat menurunkan workability dan menurukan kekuatan tekan sebesar 4,64% pada variasi 10% S325-POFA dan 8,21% pada variasi 20%. Selain itu, penggunaan S325-POFA berkontribusi terhadap penurunan emisi karbon mortar hingga 19,516% pada 20% S325-POFA, tergantung pada kadar substitusi. Penelitian ini menunjukkan bahwa S325-POFA berpotensi sebagai bahan tambahan semen yang ramah lingkungan untuk mendukung konstruksi berkelanjutan.

Abstract

The Maros-Barru railway is a strategic route to be developed as a public transportation mode that can connect two important areas in the province of South Sulawesi. However, even though the railway infrastructure in this area already exists, the level of train use by the community is still quite low. The demand for this travel need is significant for planning purposes, both facilities and infrastructure, especially transportation. The lack of public interest in trains on the Maros-Barru route is caused by several factors, one of which is the lack of information received by the community regarding the benefits and comfort offered by trains. Socialization of the benefits of rail-based public transportation will be carried out through various communication channels to reach more passengers, and it is hoped that this activity will benefit policymakers in the management and planning of trains in Sulawesi and reduce transportation problems. Before the socialization, there was no value, but after the socialization, a value of 2984 was obtained, which was in the range of 2501-3250, with the criteria Good. This means that this activity is also expected to be a preference for public transportation modes, especially trains, and the transition from other transportation modes to trains.
