Jembatan Penyeberangan Orang (JPO) dengan bentang panjang dan JPO dengan lantai bertingkat, mulai banyak di bangun di kota-kota besar di Indonesia. JPO dibangun sebagai sarana penghubung dari satu bangunan ke bangunan lainnya, sekaligus berfungsi sebagai jembatan penyeberangan lalu lintas yang berada di bawahnya. Bentuk struktur yang langsing membawa konsekuensi, bahwa struktur JPO rentan terhadap masalah getaran. Masalah munculnya getaran pada struktur JPO pada saat orang melewati jembatan, akan menyebabkan ketidak-nyamanan bagi pengguna jalan. Getaran yang muncul pada JPO dapat diakibatkan oleh karena frekuensi getar alami dari struktur JPO yang terlalu besar, atau terjadinya resonansi yang diakibatkan karena frekuensi getar beban yang melewati JPO mendekati frekuensi getar alami dari struktur. Pada perencanaan struktur JPO, asumsi bahwa beban pejalan kaki merupakan beban statik dengan hanya satu arah komponen beban kearah vertikal, adalah tidak tepat. Beberapa penelitian telah membuktikan bahwa beban orang yang bergerak merupakan beban dinamik yang mempunyai tiga komponen arah beban, yaitu arah vertikal, longitudinal, dan lateral. Dari hasil penelitian diketahui bahwa, beban pejalan kaki yang bersifat dinamik pada struktur JPO 2 Lantai, akan menyebabkan deformasi struktur 1,55 kali lebih besar Â dibandingkan dengan deformasi yang didapat dari analisis statik. Hal ini kiranya perlu diperhatikan di dalam perencanaan struktur JPO, agar didapatkan perencanaan yang memenuhi syarat kekuatan dan kekakuan, sehingga tidak menyebabkan terjadi permasalahan getaran pada saat digunakan.Â

Lithium demand increases as it is widely used as raw material for rechargeable battery, alloy for airplane, andfuel for fusion nuclear reactor. Lithium is an extremely reactive element, that it is never found as free element innature. Lithium compounds are found in earth crust, with very small concentration (20 â€“ 70 ppm) and totalcontent of more than 20 million tons. The biggest lithium reserve is in seawater (0,14 â€“ 0,25 ppm) andgeothermal water (7 ppm) with total amount of 230 billion tons. There is no industry applies the technology torecover lithium from seawater. Having a vast sea area and abundant geothermal sources, Indonesia needs todevelop a technology to recover lithium from both sources. This research is aimed to recover lithium fromgeothermal water. The experiment was conducted using synthetic and geothermal water with lithiumconcentration range of 220 â€“ 400 ppm, temperature range of 20 â€“ 40Â°C, and mixing time range of 1 â€“ 4 hours.The experiment was designed with 2 level factorial design. The results show that the most influencing variable ismixing time, while significant interaction amongst variables is not observed. Further experiment usinggeothermal water from Bledug Kuwu with initial lithium concentration of 400 ppm and temperature 30Â°Cresulted in optimum mixing time, i.e. 3 hours with 92,5% of the lithium could be recovered

Sintang Residence is a region which has susceptible region of natural disaster mainly landslide and flood.As the result of that vulnerability, it is needed to do the research to determine zonation of susceptibility ofdisaster. Zonation of landslide is based on four parameters such as slope, annual rainfall, geology factorsand land use. Zonation of flood is based on monthly/daily rainfall, land use, topographic condition andflood terrains. Based on secondary data and primary data, Sintang residence can be divided into threesusceptibility landslide zones, i.e. intermediate, low and very low susceptible landslide zones. Susceptibleflood zones are divided into three zones i.e. high, intermediate and low susceptible flood zone. Landslidesin that area are happened due to some factors; among other things are the rocks weathered, high slopedirection and no retaining wall. Flood is happened mostly due to the position of residences which straightforward or less height toward river water level and that location near with the rivers. Flood occupied theresidences mostly pass terrain edge river or pass by Sub River or rubbish ditch that ended in the mainriver. The purposes of mitigation those disasters based on the land use

Several methods for evaluating the effect of site specific condition of soil layers against earthquakes are presently available. Site Specific Analysis (SSA) and Horizontal-to-Vertical Spectral Ratio (HVSR) are two methods commonly used for estimating the amplification factor of soil layers above bedrock. SSA can be performed using subsurface shear wave velocities and dynamic soil properties (density, shear modulus and damping). The HVSR is a simple method for estimating the site amplification factor. Based on the time and budget requirement HVSR is more efficient and effective compare to SSA method.This paper presents result of SSA and HVSR methodscomparison for estimating the amplification factor of soil layers. Two boring locations and six single station seismometer tests were perform within Tembalang District Area.
