Abstract

ABSTRACT The rainfall-runoff modeling is needed to fill in the data or make the data longer. Some method can be used for forecast rainfall processing or runoff like sacramento or artificial neural network (ann). The ann is one of artificial intelligent that is an artificial representation of human’s brain which always try to simulation learning process of its. This model is a black box model, so implementation did not need complect science between many aspects in rainfall-runoff happened process. The case study on the upstream of citarum river basin (saguling dam). The data used are a rainfall data (11 rain station) , inflow and sediment rate of month during 19 years from 1986 up to 2004. Rainfall data is input and inflow rate is target output. This research use sacramento and reduced gradient method. The result for training step sacramento’s method the correlation is 81 % and reduced gradient’s method the correlation is 99 %. For testing sacramento ‘s method the correlation is 83.22 % and reduced gradient’s method alternative 2 with four hidden node gives the correlation is 65.57 %. For the next step especially the artificial neural network method still need improvement so that the artificial neural network can be used for modeling of rainfall runoff process.

Abstract

ABSTRACT One of soil foundation improvement methods to anticipate the problem of settlement is to use tire-used (pneusol). This is a preliminary study and aims to determine the reduction of vertical displacement or settlement on saturated clay reinforced with tire-used. Tire-used material generally has a density of between 8 and 10 kn/m3 and is usually classified as a material lightweight tire. Laboratory model test used 4 (four) models, model with and without tire-used and some variations of foundation model size (rollag). Ratio of the diameter of tire-used and rollag size is 0.60. Results are compared with the data obtained by plaxis program. Analysis of the plaxis program assumed that plane strain triangle element type; 6 (six) nodes element; mohr – coulomb criteria; and soil foundation in undrained condition. Results of the experimental model at laboratory works show that the tire-used can reduce the settlement of soil foundation up to 20% at maximum normal stress. However, the value of settlement obtained by experimental model at laboratory works could not be compared with the plaxis program results.

Abstract

ABSTRACT Produced pretty much every day of domestic wastewater from settlements , especially eating and drinking activities conducted by residents ranging from morning till night . Type of waste , waste volume and intensity of the waste will pollute the environment if the waste is discharged directly into the exhaust duct without any prior processing . Plus the process waste water discharges directly to the exhaust duct has been running long enough to worry about adding soil saturation liquid contaminants that would add to pollution such as odor or stench . This research will try to analyze the data from the laboratory test results of waste water from the fish pond and try to analyze if done trickling filter wastewater treatment . Keywords : effectiveness , waste water treatment, trackling filter ABSTRAK Setiap harinya dihasilkan cukup banyak limbah cair domestik yang berasal dari permukiman terutama aktivitas makan dan minum yang dilakukan oleh para penghuni mulai dari pagi hari hingga malam hari. Jenis limbah, volume limbah dan intensitas limbah akan mencemari lingkungan jika limbah tersebut dialirkan langsung ke saluran pembuang tanpa ada proses pengolahan terlebih dahulu. Ditambah lagi proses pembuangan limbah cair secara langsung ke saluran pembuang sudah berjalan cukup lama dikhawatirkan menambah kejenuhan tanah terhadap cairan pencemar yang akan menambah pencemaran lain seperti bau tidak sedap atau bau busuk. Penelitian ini akan mencoba menganalisis data hasil pengujian laboratorium dari limbah cair yang berasal dari kolam ikan dan mencoba menganalisisnya jika dilakukan pengolahan limbah secara trickling filter. Kata kunci: efektivitas, pengolahan limbah cair, trackling filter.

Abstract

ABSTRACT Have been investigated the impact of the retempering at concrete compressive strength. Retempering is adding water to the concrete mixture which already began to stiffen in the hope that the concrete is still workable. Research was done at concrete with the quality of k 225, slump value of 60-180 mm, which is in retempering with water, and concrete in retempering with water and cement. Retempering was done on concrete that has been delayed casting within 60 minutes, 120 minutes, 180 minutes and 240 minutes. The result in concrete at retempering with water decreased compressive strength, along with the addition of water. While the concrete is in retempering with water and cement with water-cement ratio (w/c) is constant, the relative compressive strength of concrete is not much different from the reference. The difference is about 4% of the compressive strength of concrete reference. ABSTRAK Telah diteliti dampak retempering terhadap kuat tekan beton. Retempering adalah penambahan air ke dalam campuran beton yang sudah mulai kaku dengan harapan beton tersebut masih dapat dikerjakan. Penelitian dilakukan pada beton dengan mutu k 225, nilai slump 60 – 180 mm, yang di retempering dengan air, dan beton yang di retempering dengan air dan semen. Retempering dilakukan pada beton yang telah didiamkan dalam waktu 60 menit, 120 menit, 180 menit dan 240 menit. Hasilnya pada beton yang di retempering dengan air mengalami penurunan kuat tekan, seiring dengan penambahan air. Sedangkan pada beton yang di retempering dengan air dan semen dengan faktor air semen (fas) konstan, kuat tekannya relatif tidak jauh berbeda dengan beton referensi. Perbedaannya kurang lebih 4 % dari kuat tekan beton referensi. Kata kunci : beton, retempering, kuat tekan, slump.

Abstract

ABSTRACT A city development is indicated by population growth and more complete facilities compare to rural area. Depok is one of city with massive development nowadays with high economic potential. In 2010, depok population is 1.675.213 peoples, this number has increase by 31.65% compare to 2000 (1.145.091 peoples), the average population growth is 3.64% per year. In line with high population growth and changing on people dynamic, most of green open space area (rth) has shifting the function into used spaced with many buildings is develop nowadays for residential (house, apartment), office building, restaurant, etc. For supporting population growth, one of the most important factor need to consider is the availability of reserved water for supporting people’s daily life. The main objective of this study was to determine the potential capacity of rain water sources to the spatial plan of depok city in 2010. Some of water source for covering all depok area are kali, situ & ground water. Currently, the usage of ground water is more dominant (used by 82.5% of total population). Based on the research result, potential source of rain water in depok is sufficient because the annual rainfall duration is very high (1106 – 4579 mm), resulting on the surplus value of dependable flow in each districts, except in beji district during dry season, in september and oktober. Keyword: rain water sources, rainfall, spatial plan.
