In planning a highway bridge girder using prestressed concrete, it must pay attention to two design categories, namely strength and service. Problems have arisen since the existence of earthquake resistance regulations for road bridges, so planners must calculate the amount of deflection and stress that occurs in the upper structure due to earthquake loads, which must be smaller than the deflection and voltage permits required by regulations. All of that was also greatly influenced by the accuracy of the predicted loss losses for prestressed concrete girders. The purpose of this study was to conduct a study which could be a solution for how to actually treat a good design, for the I-Girder design of prestressed concrete used as a highway bridge girder in the event of inaccurate prediction of loss of pressure during an earthquake, resulting in two design categories strength and service ability can be considered all well. The methodology of this study is to make as a starting point the prestressed concrete I girder whose dimensions are capable of being a highway bridge girder with a span of 30 m to 40 meters with standard loading for loading BM 100. For span bridges that have 100% prediction accuracy, use as a basic benchmark of deflection and stress values that occur for the type of combination of loads that have earthquake loads, then with the same span, varied values of inaccurate predictions lose pre-stress and analyzed deflection and stress values that occur for types of load combinations that have earthquake loads varied earthquake regions 1,2, 3 and 4, for medium soil types. The results of the study show that the greater the percentage of inaccurate prediction of loss of pressure, the greater the deviation ratio of deviations both deflection, upper fiber stress and lower fiber stress occur in the field. Which, if the prediction of losing pre-pressures is smaller than the actual one, then the level of the deviation ratio of the allowable deviation increases as well as vice versa. Also, predicting pre-suppression voltage loss that is located on the side greater than the actual loss of pressure that occurs will be on the part of the party that is harmful to the ability of service and the permissible power, when an earthquake occurs.

Polycarbonate is thermoplastic polymer group. It is easily formed using heat. Plastic has many advantages, namely thermal resistance compared to other types of plastic, resistant to impact, and very clear. The purpose of this research is to replace steel in reinforced concrete with polycarbonate and it is expected to contribute a good flexural strength on the porous concrete slab. The test specimen is 40x40x5 cm and the variation widths of polycarbonate are 2 cm, 4 cm, and 6 cm. Polycarbonates are arranged in the x direction and y direction, such as the reinforcement in concrete slab. The distance between the pores in concrete slab is 8 cm. Once the concrete aged 28 days, the next step is testing the flexural strength. The results show the concrete compressive strength is 24.699 MPa. The biggest average flexural test is in porous concrete slab with diameter of reinforcement is 6 mm. Meanwhile, for porous concrete slab without reinforcement and porous concrete slab with polycarbonate have flexural strength which is almost the same. This is because there is no bond between polycarbonate and concrete, so that the adhesion between them is very small and virtually non-existent. In addition, the results show that there is no contribution of polycarbonate flexural strength in concrete slab. Polikarbonat adalah suatu kelompok polimer termoplastik yang mudah dibentuk dengan menggunakan panas. Plastik ini memiliki banyak keunggulan, yaitu ketahanan termal dibandingkan dengan plastik jenis lain, tahan terhadap benturan, dan sangat bening. Tujuan penelitian ini adalah mengganti material baja pada beton bertulang dengan polikarbonat dan diharapkan dapat memberikan kontribusi kuat lentur yang baik pada pelat beton berpori. Ukuran benda uji adalah 40x40x5 cm, dimana variasi ukuran lebar polikarbonat adalah 2 cm, 4 cm dan 6 cm. Polikarbonat disusun dalam arah x dan arah y, seperti penulangan pada pelat beton. Selanjutnya dilakukan pengecoran. Jarak antar pori pada pelat beton adalah 8 cm. Setelah beton berumur 28 hari maka dilakukan pengujian kuat lentur. Hasil penelitian menunjukkan kuat tekan karakteristik beton adalah sebesar 24.699 MPa. Hasil kuat lentur rata-rata yang paling besar terjadi pada pelat beton berpori dengan tulangan diameter 6 mm, sedangkan untuk plat beton berpori tanpa tulangan dan dengan polikarbonat hasil kuat lenturnya hampir sama. Hal ini dikarenakan tidak adanya lekatan antara lembaran polikarbonat dan beton, sehingga daya lekat polikarbonat terhadap beton sangat kecil dan bisa dikatakan tidak ada. Selain itu, hasil menunjukkan bahwa tidak adanya kontribusi kuat lentur polikarbonat pada beton berpori.

The increasing population in Jember district has caused the higher needs of transportation facilities in Jember, particularly on train as a public transportation. The increase can be seen by the number of passengers in Daop 9 Jember. By 2015, the number of train passengers in Jember Station which originally amounted 640.000 passengers increased to 800.000 passengers by 2016 (increase about 20%). PT. KAI is planning to develop Jember Station in order to provide convenience and better service for train passengers. Jember Station development will result in changes of traffic flow around the station, so that traffic simulations due to this station development need to be done. Traffic simulations were done by creating scenarios of traffic flow around Jember Station, until the intersection performance of this area can be known. In this study, the method used to collect traffic volume data and inventory is by direct survey on field. In the calculation of intersection performance and traffic simulation, the method used is MKJI (Indonesian Highway Capacity Manual) 1997. After the analysis was conducted, the obtained intersection performance data in road network around Jember Station was very diverse. On signalized intersection, the highest intersection performance was located in SMPN 2 Jember intersection from eastern intersection in Bedadung street with Level of Service (LoS) F. Whereas on unsignalized intersection, the highest intersection performance was located in Hotel Nusantara intersection with Level of Service (LoS) C. Then, in order to obtain a better intersection performance in road network around Jember Station after development, a traffic management was done with : setting the traffic flow, installation of traffic signs on the road network, and also resetting the traffic light in signalized intersection. After the traffic management was conducted, there was a better level of service on both signalized and unsignalized intersection around Jember Station, which means the recommended traffic scenarios are proper to be implemented. Jumlah penduduk yang meningkat di Kabupaten Jember menyebabkan kebutuhan akan sarana transportasi di Jember semakin tinggi, khususnya pada transportasi umum jenis kereta api. Peningkatan yang terjadi terlihat dari jumlah penumpang di Daop 9 Jember. Pada tahun 2015 jumlah penumpang kereta api di Stasiun Jember yang semula berjumlah 640.000 penumpang meningkat menjadi 800.000 penumpang pada tahun 2016 (meningkat sekitar 20%). PT. KAI berencana untuk melakukan pengembangan stasiun Jember agar dapat memberikan kenyamanan dan pelayanan yang lebih baik bagi penumpang kereta api. Pengembangan Stasiun Jember ini akan mengakibatkan perubahan arus lalu lintas di sekitar stasiun, sehingga simulasi-simulasi lalu lintas akibat pengembangan stasiun perlu dilakukan. Simulasi lalu lintas dilakukan dengan membuat skenario arus lalu lintas di sekitar Stasiun Jember, hingga akhirnya dapat diketahui kinerja simpang pada daerah ini. Dalam penelitian ini, metode yang digunakan untuk pengambilan data volume lalu lintas dan inventarisasi yaitu dengan cara survei langsung di lapangan. Pada perhitungan kinerja simpang dan simulasi lalu lintas, metode yang digunakan yaitu metode MKJI (Manual Kapasitas Jalan Indonesia) 1997. Setelah dilakukan analisis, data kinerja simpang yang didapat pada jaringan jalan di sekitar Stasiun Jember sangat beragam. Pada simpang bersinyal, kinerja simpang paling tinggi terdapat pada Simpang SMPN 2 Jember dari kaki simpang timur atau pada Jalan Bedadung dengan tingkat pelayanan (LoS) F. Sedangkan pada simpang tak bersinyal, kinerja simpang tertinggi terdapat pada Simpang Hotel Nusantara dengan tingkat pelayanan (LoS) C. Kemudian, untuk mendapatkan kinerja simpang yang lebih baik di jaringan jalan Stasiun Jember setelah pengembangan, dilakukan manajemen lalu lintas yaitu : pengaturan arus lalu lintas, pemasangan rambu-rambu lalu lintas pada jaringan jalan, serta pengaturan ulang traffic light pada simpang bersinyal. Setelah dilakukan manajemen lalu lintas tersebut, didapat tingkat pelayanan yang lebih baik pada simpang bersinyal dan simpang tak bersinyal disekitar stasiun Jember, yang berarti skenario lalu lintas yang direkomendasikan layak untuk diterapkan di lapangan.

Asphalt is a pavement material that works as an aggregate binder and filler Natural polymer in the form of cellulose from banana stem leaves has the potential to be used as an alternative material added on asphalt to increase the quality of asphalt itself. The reason for the use of cellulose from banana stem is because it is easy to get and can reduce waste of banana stem. The design of the specimens used pure asphalt pen 60/70 mixed with banana stems fiber powder. Percentage of additive material were 0%; 0.1%; 0.2%; 0.3%; and 0.4% of the asphalt weight. The specimens made for each physical asphalt test were three samples. The results of the analysis and discussion found that the additional banana stems fiber powder on the pure asphalt produced an increase in physical characteristics of asphalt. The optimal percentage of adding banana stems fiber powder was obtained at 0.1% percentage since all test values fulfilled the 60/70 asphalt requirement. The additional banana stems fiber powder of 0.1% resulted in a decrease in penetration value from 70.7 (0.1 mm) to 67.4 (0.1 mm), ductility value from 146 cm to 102.3 cm, weight loss from 0 , 14% to 0.09%, and the specific gravity from 1.042 to 1.037. The additional banana stems fiber powder with asphalt resulted in an increase of softening point from 44.2 º C to 44.7 º C, the viscosity value from 300.99 cst to 320.80 cst. Aspal merupakan bahan perkerasan jalan sebagai bahan pengikat dan pengisi antar agregat, sehingga aspal harus memiliki kemampuan dalam mempertahankan sifat fisiknya terhadap kelenturan dan kelekatannya. Polimer alam berupa selulosa dari pelepah batang pisang memiliki potensi dijadikan alternatif bahan tambah pada aspal untuk meningkatnya kualitas dari aspal. Pertimbangan penggunaan selulosa dari batang pisang dikarenakan mudah didapatkan dan dapat mengurangi limbah batang pisang dan menjadi bahan yang bermanfaat. Metode yang dilakukan untuk membuat aspal jenis baru ini dengan mempersiapkan bahan tambah berupa pelepah batang pisang menjadi serbuk serat. Rancangan benda uji menggunakan aspal murni pen 60/70 yang dicampur dengan bahan aditif dari serbuk serat pelepah batang pisang. Prosentase bahan tambah sebesar 0%; 0,1%; 0,2%; 0,3%; dan 0,4% dari berat aspal. Benda uji dibuat masing–masing sebanyak tiga sampel untuk setiap pengujian sifat fisik aspal. Hasil analisis dan pembahasan didapatkan bahwa penambahan serbuk serat batang pisang pada aspal murni menghasilkan peningkatan terhadap karakteristik sifat fisik aspal. Prosentase optimal penambahan serat batang pisang didapat pada prosentase 0,1%, karena semua nilai pengujian memenuhi persyaratan aspal 60/70. Penambahan serbuk serat batang pisang sebesar 0,1% mengakibatkan penurunan nilai penetrasi dari 70,7 (0,1 mm) menjadi 67,4 (0,1 mm), nilai daktilitas dari 146 cm menjadi 102,3 cm, kehilangan berat dari 0,14% menjadi 0,09%, dan berat jenis dari 1,042 menjadi 1,037. Penambahan serbuk serat batang pisang dengan aspal mengakibatkan kenaikan titik lembek dari 44,2ºC menjadi 44,7ºC, nilai viskositas dari 300,99 cst menjadi 320,80 cst. Penambahan serbuk serat batang pisang pada aspal mengakibatkan penurunan nilai penetrasi dan nilai daktilitas serta meningkatkan nilai titik lembek aspal sehingga aspal lebih tahan pada temperatur yang lebih tinggi.
