<![CDATA[Penggunaan material beton pada perkerasan jalan sudah lazim digunakan yakni sebagai perkerasan kaku. Namun konsekuensi akibat penggunaan lapis perkerasan jalan adalah berkurangnya daerah resapan air akibat tertutup oleh lapis perkerasan tersebut. Dengan semakin berkurangnya daerah resapan terutama pada area parkir dan taman yang akan mempengaruhi penyerapan/infiltrasi air ke dalam tanah yang dalam skala besar dapat menyebabkan genangan air pada suatu daerah. Penelitian ini bertujuan untuk mendapatkan material beton yang memiliki tingkat permeabilitas yang cukup dengan memanfaatkan material yang umumnya menjadi limbah / sampah pada kehidupan sehari-hari Styrofoam dan menjadikannya beton yang ramah lingkungan. Tujuannya mencari nilai prosentase limbah Styrofoam meskipun kekuatan beton otomatis akan berkurang karena peningkatan nilai porositas dan permeabilitasnya dibanding beton konvensional. Metode perencanaan mix design menggunakan SNI 7656-2012 dan benda uji kuat tekan beton berupa silinder diameter 150 mm dan tinggi 300 mm. Hasil pengujian menunjukan bahwa nilai kuat tekan tertinggi didapatkan pada variasi 1 beton normal 21,39 MPa sedangkan yang terendah diperoleh beton variasi 4 (dengan prosentase penggunaan Styrofoam sebesar 30%) dengan nilai kuat 10,19 MPa ]]>

<![CDATA[Mortar salah satu material yang memiliki manfaat yang beraneka ragam dalam konstruksi bangunan. Sejauh ini, mortar konvensional digunakan sebagai bahan plester atau coating pada bangunan. Bahan pengikat utama mortar pada dasarnya masih mengandalkan semen. Pemanfaatan Batu bara pada pembangkit listrik tenaga uap masih menjadi salah satu arus utama sebagai pendukung kebutuhan energi listrik. Penumpukan hasil sisa pembakaran batu bara seperti fly ash dan bottom ash berpotensi mengganggu stabilitas Ekosistem lingkungan. Alkali-Activated mortar dengan mengandalkan larutan alkali activator yang direaksikan dengan material pozzolanic seperti fly ash, Ground Granulated Blast Furnace Slag (GGBFS), Palm Oil Fuel Ash (POFA)ldan lain-lain dapat menjadi salah satu solusi dalam mengurangi limbah fly-ash yang menumpuk. Dalam beberapa riset riset terdahulu idealnya kontrol mutu dari Alkali Activated mortar dapat ditinjiau pada kekuatan mekanisnya seperti kuat tekan dan lentur Dalam artikel ini akan ditinjau bagaimana kekuatan mekanis pada beberapa jenis Alkali-Activated Mortar. Dari studi-studi yang akan dibahas tersebut akan ditarik sebuah kesimpulan berdasarkan data-data pengujian mekanis yan pada akhirnya dapat memberi rekomendasi tentang bagaimana performa mekanis pada Alkali-Activated mortar.]]>

<![CDATA[The need for electricity supply in Indonesia is getting bigger along with the higher population growth. This gives encouragement to stakeholders to expand infrastructure development in the electricity sector. Nationally, the biggest demand for electricity is industrial sector, followed by household, business, and general sectors. In its application, the tower transmission structure has a major role to distribute the electricity needs in general. Transmission tower structure is classified as Truss structure. The truss frame is a structure consisting of a combination of rods forming triangular structures connected to each other, and encumbered in their joints. With the concept of balance of style and design of the existing code can be determined the capacity of tower and the response of the structure when carrying the primary loads, especially wind loads.]]>

<![CDATA[The danger of buckling and instability structures easily occurs on the steel beam structure, it will make the structure fails before it reaches the cross section ultimate capacity.In that case the strength of a beam is not only determined by cross-section ultimate capacity. The instability of the structure causes lateral torsional buckling eventhough there is no torque on the beam. There is one way to support the stability of the beam; by installing lateral support on its side. This research is intended to obtain information about flexural strength by comparing the theoretical results based on SNI 03-1729-2002 and (Indonesian National Standard Draft) RSNI 03-1729.1- 201x with the results of experimental testing and finite element analysis results (using the ABAQUS program). The flexural specimens which are studied are in the long-span with a length of 3.3 meters span test. The loading uses three-point load system. The results of the test show information that flexural strength for the long-span specimen from experimental test results has the smallest difference of 33.18% of the theoretical result. As for analysis with FEM also hasthe same difference of 33.18% with the experimental results. Failure that occurs for long-span specimen is due to lateral torsional buckling failures.]]>

<![CDATA[The increasing human need for motorized vehicles has an impact on the number of trips made by humans using motor vehicles will increase. This condition is seen during peak hours, namely during working hours and returning to work so that research is needed to reduce congestion and accidents that occur. Calculation of performance intersection use MKJI 1997. File of this research that got from survey in two times on one day, those are morning and afternoon. The results of the intersection research for the existing conditions produce a degree of saturation (DS) of 1.07. This value exceeds the limit suggested by MKJI 1997 for unsigned intersections (DS <0.75). some alternatives are used to improve the performance of the intersection. Alternative I is an unsignalized intersection by giving a traffic signal and produces DS = 0.92. Alternative II with geometric widening of road and traffic signal generating value DS = 0.74 and delay 32.16 det / smp. Level of intersection service is at level C which means stable traffic, travel speed and freedom of movement has been influenced by the large volume of traffic so that the driver can no longer choose the desired speed.]]>

<![CDATA[Abstract Earthquake is one of the most frequent disasters in Indonesia. This is due to the location of Indonesia which is located between 3 active plates, namely the Pacific Plate, the Indo-Australian Plate and the Eurasian Plate. While from 2018 to date the biggest and worst earthquake in the Lombok Earthquake that occurred with magnitude reached 7 on the Richter Scale and hammer earthquakes with magnitude 7.4 on the Richter Scale. One of the frequent failures caused by the earthquake is the soft store. Soft story mainly occurs in office buildings, hotels or apartments which generally have a lobby or area that is intentionally made without walls / dividers, either on the ground floor or the upper floors so that inter-floor fuss will be different. In designing and modeling structures, buildings are generally designed with open frame type port without walls. The height of the column can also cause a difference between different floors. This study will compare between the wallless portal model with a higher level at the bottom of the building, the middle of the building and the top of the building, where a high level with smaller stiffness has the potential to be soft (soft story). In this study using ETABS 9.7.2 program with spectrum response dynamic load based on the 2017 earthquake map. Results The structure period of the results of the analysis with the program in the crack cross section condition was obtained at 2.01 seconds. The shape mode for the three PPKBB, PKBT and PKBA building types has met the requirements where in shape 1 and 2 building models are translating towards the x or y axis while in shape 3 mode they are twisted. The required mass participation ratio value is reached at the 90% percentage reached at the 8th shape mode for the PKBB and PKBT buildings. While for PKBA it is reached in the 5th shape mode. Deviation values for the three types of building PKBB, PKBT and PKBA are still within the permit limit. Keywords: earthquake, soft storey, spectrum response]]>

<![CDATA[Beton merupakan material konstruksi yang paling lazim digunakan saat ini. Penggunaan beton secara massal akan berdampak pada lingkungan dengan semakin banyaknya eksplorasi material-material penyusunnya. Maka dari itu diperlukan suatu upaya untuk mengurangi resiko kerusakan lingkungan, salah satunya dengan memanfaatkan sisa limbah plastik. Bubuk fosfor strontium digunakan dengan harapan tercipta beton yang dapat berpendar saat gelap. Namun bubuk fosfor strontium masih belum banyak digunakan untuk campuran beton. Tujuan penelitian ini yaitu mengetahui pengaruh penggunaan limbah plastik dan bubuk fosfor strontium dalam hal kuat tekan beton. Penelitian yang akan dilakukan terdiri dari beberapa tahapan, pertama tahap identifikasi masalah dan bahan material penyusun beton, sehingga dapat diketahui karakteristik dari material tersebut. Tahap kedua yaitu desain campuran (mix design) beton yang menggunakan pedoman SNI 03-2834-2000. Tahap ketiga pembuatan benda uji kuat tekan dan panel beton yang dilakukan di laboratorium. Tahap keempat yaitu pengujian benda uji kuat tekan beton serta analisa hasil pengujian. Hasil pengujian kuat tekan beton terbesar yakni pada kondisi beton normal dengan nilai kuat tekan 26,03 MPa pada usia 28 hari dan yang terendah pada variasi 5 sebesar 12,83 MPa pada usia 28 hari.]]>

<![CDATA[Infrastructure development is increasing every year making the need for concrete materials increases. Using alternative materials can reduce the scarcity of material and environmental damage caused by taking and dredging the material. This research is to find out how much influence the recycled material has on the compressive strength of no fines concrete. The variations used are recycled materials of 0%, 25%, 50%, 75% and 100%. Mechanical testing conducted is a compressive strength test to determine the compressive strength of no fines concrete at the age of 7, 14 and 28 days. The ratio of cement and aggregate used is 1: 4 with FAS 0.5. This research uses 15 x 30 cm cylindrical molds with 45 test specimens. The test results show the highest compressive strength value of non-sand concrete occurs at 0% recycled material by 10.47 Mpa and the lowest compressive strength on non-sand concrete 100% recycled material is 8.39 Mpa. The percentage of absorption of no fines concrete shows that the more recycled material is used, the smaller the value of water absorption. The highest absorption value in no fines concrete is 0% recycled material, which is 5.93% and the smallest value is in the variation of no fines concrete 100% recycled material recycled material that is equal to 4.99%.]]>

<![CDATA[Using replacement materials in recent years is often used in research activities and also in construction activities. Reclaimed Asphalt Pavement (RAP) is an alternative material for use as a pavement material because it reduces the use of natural aggregates and new asphalt binders, which are needed to make asphalt mixtures. This research used a variation of RAP 0%, 25% and 35%. The test in reasearch is the Marshall test to determine the value of the optimum asphalt content and Marshall immersion. The mold of the test object used was a 3 x 4 inch cylinder with a total of 54 specimens. The results of the material characteristics test feel the 2018 highways specification standards. For the value of the Optimal Asphalt Content obtained for each variation is 5.4% for Rap 0%, 5.6 for Rap 25% and 6% for RAP 35%. In the marshall immersion test, the stability value of the remaining marshall after 24 hours of immersion was 91.4% for)% RAP, 90.7% for RAP 25% and 90.1% for RAP 35%. Keywords: AC-WC, RAP, Optimal Asphalt Content, Marshall Immersion]]>
