From year to year the Portland cement ( PC ) are known to have the price up and down. The Portland cement ( PC ) is used as a filler for asphalt mix is very limited , so it sought an alternative to the use of filler . The existence of abundant ash bagasse in sugar mills Indonesia is still not utilized properly . For now bagasse ash in Indonesian factories only used as fertilizer for sugarcane . This study aims to investigate the performance of hot mix asphalt ( HOT MIX ) LATASIR type - B ( HRSS - B ) with bagasse ash as filler material substitution using a variation of the collision. Specimens are made comprised of three major groups , namely : the test specimen using cement and bitumen of penetration 80/100 ( PC ) , the test object using bagasse ash and bitumen of penetration 80/100 with ( U.S. ) and the test object using the ash residue cane with a variation of the collision and penetration bitumen 80/100 with ( U.S. ) . Total specimen made amounted to 45 , for each type of mixture made 15 test specimens . For ( PC ) Levels of asphalt used is at 6.90% , 7.90% , 8.90 % , 9.90 % , and 10.90 % . Specifications are used to follow the standard Ministry of Settlements and Regional Infrastructure in 2001 using the Marshall method. Filler levels for each of the mixtures was 8.13% and 7.40% OBC generated . For ( AT ) levels fiiler used is 5.00 % , 10.00 % , 15.00 % , 20.00 % , and 25.00 % OBC for each - each mixture was 7.40% and the resulting levels of filler optimum bagasse ash of 7.10 % . Characteristic strength of the mixture based on the value of the stability conditions of the OBC and optimum filler levels . Carrying capacity of filler cement ( PC ) in a mixture of filler OBC 7.40% 8.13% yield and stability of the value of 720 kg , the carrying capacity of bagasse ash ( AT ) in a mixture of 7.40% OBC and filler 7.10% yield stability values 823.35 kg , while carrying a mixed impact on OBC 45 7.40% 7.10 % filler and produce value stability 840.66 kg.

This research is to know  there are any influences of variation modifier to marshall like Stability, Flow,  Marshall Quotient, and Air Void. And ideal variation mixture of Asbuton by using Pertamax as modifier.by using rate pave oil 2%, 2,2 %, 2,4%, 2,6%, 2,8%, and 3% ,  made object test counted 3 x 6 test object ( for statistical test) which in form of volume weighing cylinder 1200 grams. variation of Modifier total which used in this research are 3,75%, 3,85%, 3,95%, 4,05%, 4,15%, and 4,25% and for the each of - variation modifier use 3 test object. Stability of Marshall will reach under conditions at usage of total modifier 3,83% and will reach conditions of maximal at usage of total modifier 4,68%. From variation of modifier fulfilling conditions of  SNI-06-2489-1991 Lasbutag Cold Mix for the Stability , Flow, Air Void and Marshall Quotient which have been known, can be calculated ideal modifier for the Lasbutag Cold Mix that is ± 4,10%.Keyword : Pertamax, Lasbutag, cold mix

KORELASI ANTARA TEMPERATUR PEMADATAN PADA CAMPURAN ASPAL BETON HASIL DAUR ULANG TERHADAP STABILITAS MARSHALLCorrelation Between Compaction Temperature In Mixed Asphalt Concrete Recycling of Stability of MarshallAlik Ansyori AlamsyahJurusan Teknik Sipil Fakultas Teknik – Universitas Muhammadiyah MalangAlamat korespondensi : Jalan Raya Tlogomas 246 Malang 65144Email : alik.syah@yahoo.comAbstractRoad improvement by adding an additional layer that will result in continuous thicker pavement layer thickness and material required dwindling. Besides, with the amount of dredging mix pavement roads that are not used in some places add to the waste pile. With treatment using pavement recycling technologies (recycling) is an alternative to overcome this problem because it has several advantages such as pavement can restore and maintain strength and overcome the geometric dependence of new materials. The addition of new material and additional material or material scratch mark on the old pavement is an alternative to increase the carrying capacity of the material scratchmark. The study was conducted at the Laboratory of University of Muhammadiyah Malang Highway. The quality of asphalt concrete mixtures with the addition of recycled asphalt can only be known through the Marshall test results (stability, melting plastic, the results for the marshal, and the cavity in the mix). Used asphalt is asphalt with a penetration of 80/100 is a variation of temperature to be used is 130°C, 12°C, 110°C, 100°C, 90°C and 80°C. From the results of the research can be seen that the decrease in the solidification temperature will decrease stability, Marshall Quotient for the entire binder content. For Flow values at a temperature of 130 ° C compaction - 80 ° C showed an increase.Keywords : Temperature Compaction, Asphalt Concrete Recycling resultsAbstrakPeningkatan jalan dengan cara penambahan lapis tambahan yang terus menerus akan mengakibatkan tebal lapis perkerasan semakin tebal dan bahan yang diperlukan semakin menipis. Disamping itu dengan banyaknya campuran perkerasan dari hasil pengerukan jalan yang sudah tidak terpakai menambah tumpukan limbah dibeberapa tempat. Dengan penanganan yang menggunakan teknologi daur ulang perkerasan (recycling) merupakan suatu alternatif untuk mengatasi masalah ini karena memiliki beberapa keuntungan seperti dapat mengembalikan kekuatan perkerasan dan mempertahankan geometrik jalan serta mengatasi ketergantungan akan material baru. Penambahan bahan baru dan atau bahan tambahan pada material bekas garukan perkerasan lama merupakan salah satu alternatif untuk meningkatkan daya dukung dari material bekas garukan. Penelitian dilakukan di Laboratorium Jalan Raya Universitas Muhammadiyah Malang. Kualitas campuran aspal beton hasil daur ulang dengan penambahan aspal baru dapat diketahui melalui hasil uji Marshall (stabilitas, kelelehan plastis, hasil bagi marshall, serta rongga dalam campuran). Aspal yang digunakan adalah aspal dengan penetrasi 80/100 sedang variasi temperatur yang akan digunakan adalah 130 °C, 120 °C, 110 °C, 100 °C, 90 °C dan 80 °C . Dari hasil penelitian dapat dilihat bahwa penurunan temperatur pemadatan akan berakibat turunnya stabilitas, Marshal Quotient untuk seluruh kadar aspal. Untuk nilai Flow pada temperatur pemadatan 130 °C – 80 °C menunjukkan peningkatan.Kata Kunci : Temperatur Pemadatan, Aspal Beton Hasil Daur Ulang.

Sentani Airport serves public using air transportation with increasing people mobility conditions because Jayapura is the National Activity Center, so it causes frequent accumulation of passengers in the terminal area especially during peak hours. To determine the effectiveness of the terminal in accommodating the flow of passenger movement, it is necessary to evaluate the terminal design of Sentani Airport. The method used is to calculate the number of PWS with passenger distribution patterns, calculate the standard area of terminal capacity using references from SNI 03-7046-2004 and SKEP 77/VI/2005, calculate the terminal LOS with IATA standards, measure the airport service standards based on PM 178 of 2015, processing passengers’ perceptions with IPA and QFD methods and forecasting with simple linier regression. From the analysis, Sentani Airport terminal gives passengers mobility with low service performance value, so it is rated as less optimal. In addition, the limited availability of several facilities causes the passengers feeling less comfortable. Thus, it is necessary to re-design the passenger terminal area and re-management the facilities according to Angkasa Pura standards.
