Abstract

 This research discussed the effect of scouring on the stability of the slope on the Bujangga street STA 00+000 sd STA 00+075. A landslide had occurred in the development of a road located on the Bujangga riverside. The road is the result of widening which was previously only 2 lanes with a width of 8 m to 4 lanes with a width of 20 m. Landslides occured at STA 00+000 up to STA 00+075. At the STA the road experiences a landslide in the direction of the river to the elevation of the road surface down as deep as ± 2m. This research type is survey. Data was collected with documentation of post-landslide soil investigations, investigation of landslide conditions in the field, and sheet-pile slip simulation using the finite element method with helping the PLAXIS V.7.2 program. Data analysis with descriptive and back analysis to input soil parameters produces deformation and landslide mechanism that is relevant to actual conditions in the field. As a result of scouring of the river there is a reduction in passive pressure on the outside of the sheetpile which results in a decrease in the value of the safety factor of the road including other buildings such as settlements. This is indicated by the results of modeling and simulation above which gives the value of FS=1.2602 without scouring and FS=1.045 after scouring. The scouring of the river can be concluded that on a long-term scale the location is a landslide prone location.Keywords: Landslide Analysis, Finite Element, Road Development, Riverside  Penelitian ini membahas pengaruh scouring terhadap stabilitas lereng pada kelongsoran Jalan Bujangga STA 00+000 sd STA 00+075. Pernah terjadi kelongsoran pada pengembangan jalan yang berlokasi di pinggiran sungai Bujangga. Jalan tersebut merupakan hasil pelebaran yang sebelumnya hanya 2 lajur dengan lebar 8 m menjadi 4 lajur dengan lebar 20 m. Kelongsoran terjadi pada STA 00+000 sampai dengan STA 00+075. Pada STA tersebut jalan mengalami kelongsoran ke arah sungai hingga elevasi permukaan jalan turun sedalam ± 2m. Penelitian ini berjenis survey. Data dikumpulkan dengan dokumentasi penyelidikan tanah pasca longsoran, investigasi kondisi longsoran di lapangan, dan simulasi kelongsoran sheetpile menggunakan metode elemen hingga dengan bantuan program PLAXIS V.7.2. Analisis data dengan deskriptif dan back analysis hingga parameter tanah input menghasilkan deformasi dan mekanisme kelongsoran yang relevan dengan kondisi actual di lapangan. Akibat dari scouring atau gerusan sungai terjadi pengurangan tekanan pasif pada sisi luar sheetpile yang berakibat penurunan nilai faktor keamanan dari jalan termasuk bangunan lain seperti pemukiman. Hal tersebut ditunjukkan oleh hasil pemodelan dan simulasi di atas yang memberikan nilai FS=1.2602 tanpa scouring dan FS=1.045 setelah adanya scouring. Adanya gerusan pada bibir sungai dapat disimpulkan bahwa dalam skala jangka panjang lokasi tersebut merupakan lokasi rawan bencana longsoran.Kata Kunci: Analisis Longsoran, Elemen Hingga, Pengembangan Jalan, Pinggiran Sungai

Abstract

Indonesia merupakan salah satu negara yang memiliki intensitas gempa yang tinggi. Oleh karena itu, dalam perencanaan struktur bangunan perlu adanya studi yang lebih mendalam tentang analisis dan perencanaan struktur tahan gempa. Penelitian ini bertujuan untuk mengetahui hasil analisis bangunan 41 lantai yang ditinjau di 4 kota Indonesia berdasarkan SNI 03-1726-2012 dengan program komputer. Penelitian ini merupakan penelitian berbasis komputer, dimana bangunan 41 lantai untuk analisis dinamik spektrum respons ragam. Studi kasus bangunan dilakukan pada empat kota di Indonesia yakni Aceh, Kolaka, Yogyakarta, dan Padang. Hasil penelitian menunjukkan bahwa pada peninjauan bangunan dengan analisis dinamik ragam respons spektrum, nilai base shear dan displacement tidak begitu berpengaruh pada besarnya intensitas gempa jika dijadikan perbandingan dengan kota lain akibat lebih besarnya beban lain dibandingkan beban gempa

Abstract

The development of infrastructure in archipelago countries often faces difficulties and challenges due to the lack of fresh water. Hence, in some cases, the usage of seawater is favourable, in particular for concrete making. Little studies have been conducted on comparing the seawater, and freshwater concretes, especially on microstructure analysis. The objective of this study was to reveal the compressive strength, elasticity, and microstructure of concrete using seawater and freshwater as the mixing water. The methodology of this study was mix design, making test specimens, curing test specimens, and microstructure analysis. The tests of concretes were conducted for each sample with variations of 1, 3, 7, and 28 days and the mechanical behavior were tested using compressive strength and elasticity as parameters. At the same time, the microstructure was examined using an X-Ray Diffraction (XRD). The results showed an increase in compressive strength and elasticity of seawater and freshwater concretes at all variations with insignificant differences observed between the two types of concretes. It was also discovered that the formation of Friedel's salt (3CaO.Al2O3.CaCl2.10H2O) in the seawater concrete was not in the freshwater concrete. In conclusion, the differentiation of microstructure did not significantly affect the compressive strength and elasticity between seawater and freshwater in mixing concrete.

Abstract

Water is a natural resource that is crucial for the survival of all living beings, including humans. The quality of water is an important factor that can have a significant impact on human health. To ensure the well-being of the community, water quality testing was conducted at 2 drilled wells that are being used by residents of Anaiwoi Village. Based on the water quality testing results, it was found that the pH value at point 1 was between 4,6-4,8, while at point 2, it was between 4.6 - 5.9. Unfortunately, the pH values at both points were below the Environmental Health Quality Standards. On the other hand, the Total Dissolved Solid (TDS) parameters at both points were found to be within the Environmental Health Quality Standards. This is because the TDS values obtained were less than 300 mg/L or less than 300 ppm.

Abstract

Medical waste is produced in hospitals by a variety of means, including solid waste, gas, and liquid. Therefore, it is necessary to support the analysis of the production of solid medical waste at RS SMS Berjaya District of Kolaka. The purpose of this technical support is to find out the monthly quantity of solid medical waste as well as the solid medical waste disposal system carried out at SMS Berjaya Hospital. Use both qualitative and quantitative descriptions. The accompanying results showed that the solid medical waste produced from medical activities in each room during the observation was a source of non-acute infectious garbage. Class II and III hospital facilities produce the highest percentage of medical garbage 23.13 kg/day (46.26%), and the smallest unit of medical waste in each room is 2.59 kg/ day (5.18%). And in the Infectious Object Garbage, the largest in Class II & III facilities is 1.32 kg/day (29,53%). And Nifas/Perinatology facilities are much smaller than 0.4kg/day (8.95%). SMS Berjaya Hospital has a solid, well-implemented medical waste management system.
