Abstract

ABSTRACT   Flood is known as a disaster that usually comes suddenly, and therefore, people are not prepared. As a result, it causes a dead loss, both human and material. In order to anticipate flood, some dikes have been built. Bengawan Solo dike has changed through time. Damages along the dike have been identified and followed-up by conducting some improvements to make it function well. However, since the repairs are carried out based on the occurrence of landslide or burst, there are many portions of the dike that are damaged but receive no rehabilitation. In fact, in some portions of the dike crossing densely populated settlements, there are many buildings cutting through the outside part of the dike base. Furthermore, portions of the dike in that area have been transformed to street with uncontrolled load. For example, it is found that some vehicles loading construction materials passing on the dike. But, in fact, this sort of loading has not been predicted in the planning. Hence, it is important to foreknow the benchmark of dike performance to assess the performance of dike before landslide or burst occurring. This research was conducted to the Jurug-Mojo portion of Bengawan Solo dike. It is 1.317 m long and is divided into 13 portions, each of which is 100 m long. The parameters applied in this research were cross-section, dike elevation and data about land, while the variables were debit, gravity acceleration, water surface elevation, soil pore index, shearing force, specific weight, and friction angle. There were 3 (three) methods proposed to assess the benchmark of the dike performance, including reliability assessment, dike surface assessment (PCI Mmethod) and dike stability assessment (Bishop Mmethod). The findings of the research are as follows. The maximum debit that can be embanked by the dike is 1,489 m3/s; the reliability index is 0.675; the PCI index is 59.4 (good); the dike stability index before overtopping is 2.771 (stable); the dike stability index when overtopping is 1.075 (unstable), the water stability index when lowering 1 m is 1.775 (stable). Keywords: dike, reliability index, stability, PCI (Pavement Condition Index)

Abstract

AbstractStiffness modulus of asphalt concrete mixture is one of the most important parameters for the flexible pavement design that is very susceptible from temperature and time loading. The stiffness modulus here may be defined as a measure of the load spreading ability of material. The stiffness of asphalt mixture can be measured through various laboratory researches and empirical methods. Various laboratory researches have been employed to measure this property of asphalt such as indirect tensile modulus test, ITSM.The aims of this research were to achieve the viability of using asphalt 60/70 pen with different temperature on strength and stiffness modulus on thin layer HMA (4 cm) compared to Asphalt Concrete Wearing Course (6.8 cm). The other purpose is to get to know the effect of the using thin layer HMA (4 cm) in different climate region. All of the asphalt concrete mixtures of thin layer HMA and AC-WC which were used in this research based on Marshall Mix design according to Indonesian standard (Bina Marga 2010). The laboratories tests which have been conducted in this research were: indirect tensile strength (ITS), unconfined compressive strength (UCS) and indirect tensile stiffness modulus (ITSM) at temperature 10°C, 20°C, 40°C and 60°C.In comparison with the results of indirect tensile strength test, indirect tensile stiffness modulus test and unconfined compressive strength test, it is noticed that the strength and stiffness modulus of thin layer hot mix asphalt was affected by the temperature which the temperature degree might increase to decrease or the way around. From the results of ITSM test for HMA and AC-WC showed that starting from the temperature 20°C to 60°C there is no significant value of stiffness behavior at them. However, there is slight different value at temperature 10°C mixture respectively. Keywords: Thin layer, AC-WC ,

Abstract

AbstrakKerusakan jalan yang terjadi di beberapa ruas jalan menimbulkan kerugian yang sungguh besar terutama bagi pengguna jalan seperti waktu tempuh yang lama, kemacetan, kecelakaan, dan lain-lain. Selain itu kendaraan yang melaju dalam kecepatan lambat memancarkan emisi yang lebih besar, dan emisi yang besar berpengaruh pada kesehatan manusia.  Penelitian ini mengkaji seberapa besar pengaruh kerusakan jalan terhadap kecepatan kendaraan dan selanjutnya berpengaruh pada emisi kendaraan bermotor. Tahapan penelitian ini meliputi penilaian kondisi perkerasan yaitu dengan metode PCI, kemudian dari hasil penilaian kondisi perkerasan dipilih enam lokasi dengan kondisi perkerasan yang berbeda (excellent, very good, good, fair, poor, very poor) dan dihitung kecepatan rata-rata kendaraan pada lokasi tersebut. Dan tahap selanjutnya dihitung nilai emisi pada enam lokasi tersebut dengan menggunakan softwer mobilev. Hasil penelitian ini menunjukkan bahwa pada jalan dengan kondisi excellent, kecepatan rata-rata kendaraan adalah 65,38 km/jam dan emisi CO sebesar 20818,63 g/jam/km, emisi CO2 sebesar 1632864,82 g/jam/km, emisi NO2 sebesar 476,39 g/jam/km, emisi Particulate Mass sebesar 168,078 g/jam/km, Emisi SO2 sebesar 4,262 g/jam/km. Dan pada jalan dengan kondisi very poor, kecepatan rata-rata kendaraan adalah 29,09 km/jam, emisi CO sebesar 21393,74 g/jam/km, emisi CO2 sebesar 1671812,447 g/jam/km, emisi NO2 sebesar 488,74  g/jam/km, emisi Particulate Mass sebesar 172,238  g/jam/km, Emisi SO2 sebesar 4,359  g/jam/km. Dapat disimpulkan bahwa terjadi penurunan kecepatan rata-rata sebesar  55% pada jalan dengan kondisi very poor dibandingkan dengan jalan kondisi excellent dan terjadi peningkatan emisi gas buang kendaraan rata-rata sebesar 2,49 % pada jalan dengan kondisi very poor dibandingkan dengan jalan dengan kondisi excellent. Maka dari itu sangat perlu menjaga kondisi jalan agar tetap dalam kondisi excellent. Kata kunci: kerusakan jalan, kecepatan kendaraan, emisi gas buang kendaraan

Abstract

AbstractSelf-compacting concrete (SCC) is a flowing concrete mixture that is able to consolidate under its own weight. Many countries have the problem of shortage of conventional cementing materials. Recently there is  considerable  efforts  worldwide  by  utilizing indigenous and waste materials in concrete. One of  such  materials  is  the  rice  husk  which  under controlled burning. Rice Husk Ash (RHA), produced after the burning of Rice husks (RH) has high reactivity and pozzolanic property. The use of RHA in this experiment is expected to determine the effect of RHA on Self Compacting Concrete. The use of Rice Husk Ash of Self Compacting Concrete as a matrix cannot increase the compressive strength of the SCC. Highest value obtained at RHA 0% of 27.18 MPa and RHA 20% of 22.08 MPa. Silica (SiO2) content in RHA of 82.59% (due to uncompleted burning) showed insufficient standard value required to produce optimal CSH bond on concrete,  which is silica content of at least 85% to increase the strength of concrete. Temperature reaction increases due to the increasing of calcium oxide. This condition makes more calcium hydroxide released by cement when cement reacts with water. With the higher of calcium hydroxide so that the adhesion of cement will be reduced and makes the structure weaker and then cause a lower compressive strength. Keywords: SCC, fly ash, RHA, consistency, compressive strength

Abstract

Proyek Konstruksi merupakan bentuk kegiatan yang berlangsung dalam jangka waktu terbatas, dengan sumber daya tertentu, untuk mencapai hasil dalam bentuk bangunan atau infrastruktur. Dalam pelaksanaan proyek konstruksi sering terjadi keterlambatan yang disebabkan oleh pihak-pihak yang terlibat. Keterlambatan proyek konstruksi dapat didefinisikan sebagai terlewatnya batas waktu penyelesaian proyek dari waktu yang telah ditentukan dalam kontrak, atau dari waktu yang disetujui oleh pihak terkait dalam penyelesaian suatu proyek. Keterlambatan proyek akan menyebabkan pembengkakan biaya serta hilangnya peluang untuk mengerjakan proyek yang lain. Oleh karena itu, penelitian ini dilakukan dengan tujuan untuk mengetahui faktor-faktor penyebab, dampak, dan cara mengatasi keterlambatan proyek yang dilakukan dengan menyebarkan kuisioner kepada 30 kontraktor yang berperan penting dalam proyek-proyek besar di Rosalia Indah Group. Dampak keterlambatan proyek dapat diindikasi menggunakan indikator biaya, waktu, dan pembayaran yang terlambat. Metodologi penelitian yang digunakan adalah deskriptif kuantitatif. Validitas dan reliabilitas data dianalisis diuji dengan SPSS (Statistical Product and Service Solutions). Kemudian hasil analisis dilakukan dengan menggunakan metode AHP (Analytical Hierarchy Process) supaya didapatkan bobot dari hasil survey kuisioner. Berdasarkan hasil analisis, diperoleh prosentase prioritas kriteria 5 faktor keterlambatan proyek di Rosalia Indah tertinggi yaitu: terjadinya perubahan desain oleh owner, perubahan spesifikasi pada saat proyek masih berlangsung, adanya pekerjaan tambahan, pelaksanaan jadwal proyek yang tidak sesuai, dan kekurangan tenaga kerja.

Abstract

AbstractHot arid region is a region when it is characterized by a severe lack of available water and has a high temperature like Australia and Africa. In this condition, hot mix asphalt (HMA) thin surfacing is chosen for road preservation. This study is aimed to study about modified asbuton for hot mix asphalt by thin surfacing overlay.For bitumen modified, researcher used three types of asphalt (asphalt penetration 60/70, retona blend 55 and polymer SBS) specimen which be add with 5%, 5.5%, 6%, 6.5% and 7% for each sample with thickness of 30mm. Moreover, for the temperature test, it was tested at 20oC until 60oC. The test showed that polymer SBS can be used as a binder for alternative industrial asphalt in flexible pavement at hot and arid region. Polymer SBS is good material that has same sensitivity in the different temperature. Result of marshall test showed that Polymer SBS more stable than asphalt penetration 60/70 and retona blend 55. Polymer SBS also has the highest density. Retona blend 55 has the better result for the test average that was conducted in this study.Keyword: HMA, thin surfacing, asbuton, bitumen, hot and arid.
