Abstract

The most current Indonesia National Standard on earthquakes SNI 03-1726-2012 is designed to anticipate the latest earthquake events in the past decade. This standard as well as the former SNI 03-1729-2002 incorporates the guidance for Ordinary Moment Resisting Frame Systems(SRPMB)andSpecial Moment Resisting Frame Systems (SRPMK). This study evaluates the performance steel frames based on the two standards for high, and intermediate seismic regions with a variation in soil conditions. The aim of this study was to obtain the most appropriate structural steel system for high and intermediate earthquake regions. The analysis was performed with the aid of a structural analysis program, and approached as a two-dimensional case. The responseof earthquake loads was analyzed by the dynamic response spectrum modal analysis on 8, 10 and 12 storey buildings. The Semarang area was chosen for the intermediate seismic response, while Banda Aceh functioned a prototype for the high seismic area. Three soil types were taken into consideration; hard, medium and soft soil. The study showed that the nominal of the earthquake load in the area of Banda Aceh was approximately equal to 164% of the nominal earthquake load in Semarang. For the variations in soil type it was found that for the Semarang as well as the Banda Aceh region, the nominal earthquake loads on a steel structure based on the SRPMB was approximately equal to 228,6% to the SRPMK. Further it was concluded that the SRPMK steel stucture was able to reduce the earthquake load by approximately 87,5% as compared to the SRPMB steel structure that resulted in an earthquake load reduction of 71,4%. It was therefore advised to use the SRPMK in designing steel structures for areas in high seismic regions, whiles for the medium seismic regions the both the SRPMB and the SRPMK method will yield in an optimum design.

Abstract

Pada tugas akhir ini, penelitian aspal diambil mengenai perbandingan kualitas Hotmix aspal dengan sample aspal minyak tua yang diolah secara konvensional dari daerah Kabupaten Grobogan dan aspal Pertamina penetrasi 60/70. Pedoman utama dalam penelitian aspal ini adalah berdasarkan SNI 8135 : 2015 dan RSNI M-01-2003. Dari hasil penelitian diperoleh aspal Pertamina penetrasi 60/70 memiliki nilai penetrasi 71, titik lembek aspal 52 ˚C, titik nyala dan titik bakar 286 ˚C, daktilitas 110 cm, kelarutan aspal dengan CCL4 99,33%, dan berat jenis bitumen 1,043 gr/cc, sedangkan aspal sumur minyak tua memiliki nilai penetrasi 390, titik lembek aspal 36 ˚C, titik nyala dan titik bakar 51 ˚C, daktilitas 0 cm, kelarutan aspal dengan CCL4 92,67%, dan berat jenis bitumen 1,0177 gr/cc. Sehingga aspal Pertamina penetrasi 60/70 memenuhi syarat aspal penetrasi 60/70, sedangkan aspal sumur minyak tua tidak masuk ke dalam standart spesifikasi aspal penetrasi 200/300. Nilai penetrasi yang tinggi, nilai daktilitas yang rendah, dan nilai kelarutan aspal dengan CCL4 yang rendah dipengaruhi oleh prosentase senyawa C11H12D6O yang rendah, sehingga untuk meningkatkan kekakuan aspal sumur minyak tua perlu dilakukan penambahan prosentase senyawa C11H12D6O. Nilai Kalium pada aspal sumur minyak tua yang rendah mengakibatkan titik lembek aspal rendah, sehingga aspal sumur minyak tua perlu ditambahkan Kalium untuk meningkatkan nilai titik lembek. Nilai titik nyala dan titik bakar aspal sumur minyak tua yang rendah dipengaruhi oleh banyaknya senyawa pengotor yang mudah terbakar seperti oksigen, parafin, dan minyak, maka perlu dilakukan pemisahan kandungan senyawa pengotor pada aspal sumur minyak tua. Pada pengujian Marhsall, dengan menggunakan aggregat halus dan aggregat kasar sama yang memenuhi syarat berat jenis agregat, penyerapan agregat, abrasi agregat, dan Impact Test diperoleh kadar aspal optimum untuk aspal Pertamina penetrasi 60/70 sebesar 5,7%, sedangkan aspal sumur minyak tua tidak ditemukan kadar aspal optimumnya. Oleh karena itu, aspal sumur minyak tua lebih cocok untuk lapis pondasi jika dilakukan penambahan nilai prosentase senyawa C11H12D6O, sehingga nilai penetrasinya maksimal 200.

Abstract

Soedarto Roundabout is an icon of Engineering Faculty Complex in Diponegoro University. Tis roundabout becomes a potential location for traffic violations, as it is shifted from the existing junction. Some travellers use it as a shortcut route therefore the traffic performance decrease. Thus, it is necessary to design some alternatives to increase the performance and traffic order. This study aims to identify the traffic characteristics in roundabout area, design some alternatives of intersection management, and determine the best alternative proposal. The quantitative method used in performance analysis of roundabout and the surrounding road network is based on Indonesian Highway Capacity Manual (MKJI, 1997). The qualitative method used is the Analytic Hierarchy Process (AHP) Method. The result shows that traffic order level in this area is quite low, due to many violations caused by the shortcut movements. The number of violation increase in off-peak time. The Degree of Saturation value (DS) of Soedarto Roundabout is 0.88, and the DS of Peternakan Intersection is 0,93. Three alternatives of intersection management in Soedarto Roundabout Area are the change of roundabout and median geometric into priority intersection, chanelization, and roundabout blocking. The quantitative analysis shows that the performance of the third alternative is quite good, with the DS of weaving area between Soedarto Roundabout and Peternakan Junction is 0.70, and the DS of Peternakan Junction is 0.83 (after extended). Thus, the qualitative analysis using AHP shows that the third alternative is the best.

Abstract

ABSTRAKMortar merupakan campuran semen, pasir, dan air dengan proporsi tertentu. Pada umumnya bahan ikat campuran yang digunakan adalah semen. Unsur utama pembentuk semen itu sendiri adalah silika, alumina, dan kalsium. Kandungan silika dan alumina pada semen dapat pula diperoleh dari fly ash sedangkan kandungan kalsium dapat diperoleh dari tanah putih. Dalam penelitian ini akan dibuat mortar yang menggunakan campuran fly ash, tanah putih, dan pasir yang akan diteliti mengenai kuat tekan mortar tersebut. Variasi perbandingan fly ash dan tanah putih dengan persentase masing - masing sebesar 0%-100%, 25%-75%, 50%-50%, 75%-25%, dan 100%-0% dalam campuran mortar. Bentuk benda uji yang digunakan berbentuk kubus berukuran 5 cm x 5 cm x 5 cm. Mortar dibuat dengan metode adukan manual. Hasil penelitian menunjukkan adanya pengaruh persentase tanah putih dan fly ash terhadap kuat tekan mortar. Kuat tekan tertinggi pada umur 28 hari ditunjukkan oleh varian mortar dengan persentase fly ash dan tanah putih 50%-50%, yaitu sebesar 2,218 kg/cm2. Nilai kuat tekan mortar yang menggunakan fly ash dan tanah putih tersebut masih sangat rendah, sehingga campuran fly ash dan tanah putih tidak dapat digunakan sebagai pengganti semen bahan konstruksi.
