Abstract

Sinduadi urban settlements with rapid population growth as a result of the growth of property, shopping, industry, campus and tourism businesses have the potential to create slum areas. Based on the 2016 Sleman Regent Decree in RT 011 RW 026 Kutu Dukuh have an area of 1.23 hectares of slums. To decrease size of slum areas, it is necessary to study calculations in accordance with applicable regulations. The purpose of the study was to identify the parameters determining the slum, calculate slum scores, reduction in slum area and slum level at the end of 2018. Data were taken from survey results and the Sleman KOTAKU Program document. From the analysis of slum measurements with 19 parameters the value is 23 (light slum category) measured based on PUPR Regulation No. 2/2016 which uses 7 aspects and 19 parameters, such as the limitations of building conditions, roads, clean water, waste management, drainage and the unavailability of hydrants. The initial calculation results show a score of 23 consisting of the unavailability of drainage value of 3, a waste management system that does not conform to the technical standard of value 5, the non-maintenance of waste management facilities and infrastructure of value 5, and the unavailability of a fire protection facility of value 5. For handling investment is required in the form of paving roads ( 853.5 m2), rainwater infiltration wells (18 units), drainage channels (154.5 m1), public hydrants (HU) clean water (10 units) and 3R waste (39 kk) which become the final score of 14 (< score 19) which means not slum.

Abstract

The foundation has a function to hold the load in the form of axial load, lateral load and moment. The axial load on the pile foundation is supported by the pole end resistance and pile friction, while the lateral load on the pile foundation is supported by the relation of the blanket area along the pile with the ground in the lateral direction. Lateral load causes lateral deflection in which the magnitude of deflection must not exceed the permissible lateral deflection limit of 2.54 cm. The determining factors in lateral deflection are the type of pile foundation, soil type, and the magnitude of the force that occurs. The foundation of a single pile in which the number of one pile when embedded in clay soil needs to be investigated for the magnitude of lateral deflection that occurs, this is due to the changing nature of the clay when under the influence of high or low water content. The foundation of the pile uses a concrete head with the condition of a free end with a cylindrical shape with a diameter of 60 cm that is not solid with a wall thickness of 10 cm and a compressive strength of concrete of 60 MPa. Clay soil data uses soil drilling test data in Wirosari, Grobogan, Central Java. The planning method used is the finite element method (PLAXIS) and the finite difference method (p-y curve and the ALLPILE program) with lateral load variations of 10 kN, 15 kN and 20 kN given to the top end of the pole with the principle of giving trial and error loads. The results of the calculation of the lateral deflection of the pile on the p-y curve method with finite difference resolution, the ALLPILE program, and the PLAXIS program respectively with a lateral load of 10 kN are 0.0629 cm; 1.21 cm; 0.27 cm, lateral loads of 15 kN are 0.0943 cm; 2.13 cm; 0.4051 cm, and a lateral load of 20 kN is 0.1258 cm; 3.14 cm; 0.5402 cm. Thus the lateral deflection load limit is 15 kN, so as not to exceed the permissible lateral deflection limit of 2.54 cm. The recommended method used is the ALLPILE program to better get the level of security from the lateral deflection of the pole when applied in the field.

Abstract

Pile bearing capacity, is an important parameter in infrastructure design. The pile driving process, especially in saturated clay soils, results in an increase in pore pressure which affects the bearing strength capacity of the pile foundation immediately after erection. By knowing the com-parison of various ways to calculate the bearing capacity of a pile foundation, especially in clay soils, various influencing parameters can be studied and to be taken in determining the bearing ca-pacity of a pile foundation. The test is carried out by comparing the value of the pile bearing capacity of a laboratory scale pile model with the results of the calculation of the pile bearing capacity using the static analysis method based on the results of the test parameters of the soil. The clay soil con-ditions in the test are limited to saturated conditions. The reading of the change in pore water pres-sure is carried out using a pressure transducer during the pile driving process. Based on the pile loading test results in the laboratory, the pile bearing capacity results were 0.31 kN, while the bearing capacity results based on the static analysis method were 0.75 kN. The difference in pile bearing carrying capacity is caused by excess pore water pressure that appears around the ground during the driving process.

Abstract

Salah satu pusat kegiatan yang perlu analisis dampak lalu lintas adalah gedung pertemuan. Namun, standar tarikan perjalanan belum ada dan akan memberi dampak pada ruas jalan di sekitarnya. Oleh karena itu penelitian ini memiliki tujuan untuk mengetahui besaran tarikan perjalanan serta dampak lalu lintas yang terukur akibat adanya gedung pertemuan pada ruas jalan dan simpang tak bersinyal di Kota Palu. Penelitian dilakukan pada gedung Mary Glow (MG) sebagai salah satu gedung pertemuan terbesar di Kota Palu. Perhitungan tarikan perjalanan menggunakan analogi dari Gedung MG sebelumnya. Survei tarikan perjalanan dilakukan dengan menghitung traffic movement per 15 menit di pintu masuk Gedung MG dan simpang tak bersinyal selama event dan tidak ada event kemudian dibandingkan. Kinerja ruas jalan dan simpang tak bersinyal berdasarkan MKJI 1997. Hasil penelitian menunjukkan bahwa besaran tarikan perjalanan dapat ditentukan berdasarkan kendaraan yang keluar-masuk area gedung pertemuan dengan menggunakan analogi terhadap kapasitas gedung. Kasus pembangunan Gedung MG untuk lima tahun mendatang menunjukkan bahwa pengoperasian gedung pertemuan dapat menurunkan tingkat pelayanan secara signifikan pada simpang tidak bersinyal yaitu dari tingkat pelayanan C menjadi D, sedangkan pada ruas jalan tidak signifikan yaitu tingkat pelayanan tetap B.

Abstract

Sedimentasi waduk menjadi salah satu masalah kompleks yang harus ditangani secara tepat. Banyak upaya pemeliharaan waduk yang dilakukan agar umur teknis waduk dapat bertahan sesuai perencanaan, salah satu diantaranya adalah pengeluaran sedimen dari dalam waduk dengan cara flushing. Flushing atau penggelontoran sedimen dalam jumlah yang masif menjadi salah satu solusi yang ditawarkan untuk mengurangi sedimen yang terlanjur mengendap guna mencapai efektivitas dan efisiensi pembuangan sedimen dari dalam waduk. Waduk Mrica merupakan salah satu waduk di Indonesia yang rutin melakukan flushing sebagai upaya pemeliharaan. Flushing Waduk Mrica melalui drawdown culvert (DDC) sudah dilakukan sejak tahun 1992 namun volume aktif waduk semakin menurun setiap tahunnya. Tujuan dari penelitian ini untuk mengevaluasi kinerja flushing dengan menghitung nilai flushing feasibility dengan mendasarkan pada praktik atau pelaksanaan flushing Waduk Mrica selama ini serta berdasarkan kriteria dan rumus pendekatan. Hasil analisis menunjukkan bahwa nilai efektivitas tertinggi adalah pada tahun 2014 dengan nilai 0,059 untuk Metode Morris & Fan dan Metode Qian, dan 0,067 untuk Metode Lai & Shen. Sedangkan untuk Metode Ackers & Thompson menghasilkan nilai 0,858. Hasil perhitungan feasibility study menunjukkan bahwa flushing yang dilakukan Waduk Mrica pada tahun tertinjau belum dapat dikategorikan layak dikarenakan kriteria Sediment Balance Ratio with Full Drawdown tidak terpenuhi. Penelusuran waduk menunjukkan bahwa adanya konsistensi nilai head loss coefficient dengan range nilai 3,98 sampai dengan 4,14 pada penggelontoran sedimen di Waduk Mrica. Sehingga dapat disimpulkan bahwa flushing dapat mencapai feasible dan efektif bila dilakukan pada saat inflow mulai naik, durasi melebihi 13 jam, dan debit flushing mencapai 280 m3/s.

Abstract

The retention basin at the Faculty of Engineering Gadjah Mada University was built as a flooding control into the Code river and improving the water quality. The water entering the basin, especially in the dry season, is characterized as greywater due to the dense settlements around the university. The purpose of this study was to determine the effectiveness of reaeration process using a Microbubble Generator (MBG) to increase DO, with the aim of this leading to an improved water quality. The MBG aerator with submersible pumps was installed at a depth of 40 cm from the water surface and placed in the middle of the pond. The aerator was permanently turned on. In situ monitoring of DO was carried out using a seri Lutron WA-2017SD DO meter. The increasing DO correlated with the changes of the surrounding weather which impact on water and air temperature. At the time of DO data collection, the water temperature ranged from 24.5oC - 27oC and the change in DO measured at the inlet and outlet of the reservoir was in the range 0.3 - 1.1 mg/l, with the DO directly surrounding the aerator reaching up to 2.4 mg/l from the inlet. With the DO increased, the concentration of pollutant organic loads can be reduced and the nitritation and nitratation processes has taken place properly so that it has reduced the pollutant load before the water enters the Code river.

Abstract

Selama ini penentuan kelas hambatan samping jalan dan kapasitas ruas jalan hanya didasarkan pada frekuensi kendaraan masuk/keluar sehingga nilai derajat kejenuhan yang diperoleh tidak dapat digunakan untuk menggambarkan dampaknya terhadap gangguan perjalanan. Studi ini difokuskan pada penilaian dampak manuver belok kanan terhadap kelancaran dan keselamatan perjalanan sehingga penilaian kinerja didasarkan pada derajat kejenuhan, tundaan dan risiko kecelakaan. Risiko adalah fungsi dari peluang terjadinya kecelakaan dan konsekuensi yang dapat ditimbulkannya. Peluang tersebut diukur melalui nilai faktor keselamatan dan konsekuensinya ditentukan berdasarkan prakiraan kecepatan kendaraan saat benturan antara kendaraan arus mayor dan masuk/keluar SPBU. Ditemukan bahwa walaupun rasio arus belok kanan akibat manuver kendaraan masuk/keluar SPBU relatif rendah, namun 1) berdampak pada tundaan perjalanan yang cukup tinggi 2) peluang kecelakaan cukup tinggi karena sejumlah pengendara melaju dengan kecepatan di atas 50 km/jam 3) celah penyeberangan kritis rerata adalah sekitar 20 m sehingga dengan pilihan kecepatan tersebut potensi kecelakaan fatal mendekati 80%.
