InÂ the process of planning, design and management of water resources system, a long term data on hydrology is needed in order to obtain good analysis and final result. In Indonesia, usually it is very difficult to get a complete and appropriate data on hydrology at certain locations. To cope with the constrains and lack of data on hydrology as is mentioned above, experts on hydrology tend to solve the problems with the following methods: Stochastic analysis, Correlation and regressions analysis, and Simulation analysis on the watershed. In this paper, the phenomenon of the distribution of annual rainfall to monthly rainfall will be discussed utilizing stochastic analysis (i.e. temporal disagregation model), by presserving their statistical characteristics. The output of this model, which is quite reliable and can be use, among other, as a sound base for development of water resources and flood control.Permalink: http://www.ejournal.undip.ac.id/index.php/mkts/article/view/3926[How to cite: Wahyuni, S.E., 2005, Distribusi Data Tahunan Menjadi Data Bulanan, Jurnal Media Komunikasi Teknik Sipil, Volume 13, Nomor 3, pp. 106-116]

Time series analysis applied to hydrological data is generally used to forecast the in coming series of data such that use can make use of the information to manage, control, and anticipate the posible occurence of natural phenomena. This paper applied time series analysis to discharge data at Kali Kunto, Central Java. The data shows that the annual discharge at Kali Kunto tends to follow an ARMA (1,1) to ARMA (2,2). The appropriate ARMA model can be obtained through calibration stage. Keywords: time series analysis, discharge patternPermalink: http://ejournal.undip.ac.id/index.php/mkts/article/view/3908[How to cite: Wahyuni, S.E., 2005, Menentukan Pola Debit Rata Rata Tahunan, Jurnal Media Komunikasi Teknik Sipil, Volume 13, Nomor 2, pp. 50-56]

Stochastic models are models to generate new data series based on historical data and have similar statistical parameter with statistic historical data. Methods of forecasting are developed base on statistic and mathematic science. The historical data are observed data or sample data. The limited data is become main constrain for extrapolation of data. The mean error of generated data should be lower than 5%, its mean data of generated have the validation rate on 95 %. Three samples location for study are Catchment of Bengawan Solo in Bojonegoro, Catchment of Serang in Kedungombo - Grobogan and Catchment of Citarum in Cirata - Bandung. The synthetic data and then is used to calculate the statistic parameter. Error of generated data is measured with relative error. The relative error is result of divided and subtract statistic parameter of generated data and the statistic parameter of historical data longest and statistic parameter of generated data. The result of data length analysis is relative error and historical length of the data. The analyzed result indicate that historical data are studied have representative historical data about 30 years length of data.Keywords: stochastic, historical data, synthetics data, representative data length and relative errorPermalink: http://www.ejournal.undip.ac.id/index.php/mkts/article/view/2093[How to cite: Gunawan, S., Wahyuni, S.E. dan Suharyanto, 2006, Kajian Panjang Data Historis yang Representatif pada Model Stokastik, Jurnal Media Komunikasi Teknik Sipil, Volume 14, Nomor 2, pp. 129-141]

Flood is a condition where areas that normally are not inundated by water such as settlements, and other public facilities become stagnant. The impact of flood disasters is very detrimental both morally and materially as delays in transport lines which impact on the pace of the economy. Semarang city is one of the areas in Indonesia are prone to flooding. The condition worsened with a decrease in the land throughout the year reached 0.7 to 11.2 cm / year. Starting from Ivory Pucang weir, river silting baboon suffered due to sedimentation, thereby reducing the capacity of water drainage caused flooding in the area around the river. This study using HEC-HMS software to analyze the flood discharge with a return period of 2, 5, 10, 25, 50 and 100 years. From some of the return period flood discharge plan, for further analysis taken flood discharge plan with a return period of 100 years. The program has been calibrated using the flood discharge at the dam hourly Pucang Ivory. HEC-HMS addition, this study also uses the HEC-RAS software to analyze the profile of the river water level and produce a flood inundation area of flood discharge plan with a return period of 100 Pathe obtained from the processing of data for flood inundation in the area Sayung, Kab. Demak, so the need to improve cross-section.

As Jakarta developed into a metropolitan city, flood problems become the center of attention for its citizens and the government of Jakarta. Ciliwung River is one of the significant contributors to flood discharge in Jakarta. Flood control in Jakarta area requires a very hard effort, considering the geological conditions which is an area of the basin and hydrological conditions are very vulnerable to inundation because bypassed by many rivers from upstream. Changes in land use that was once empty land converted to settlements, housing, and the building also has occurred both in the upstream and downstream along the rivers that pass through Jakarta. After an evaluation of watershed and watershed Krukut Sunter which is around Ciliwung watershed, it was found that there were streams of the watershed around the exit and entry into the Ciliwung watershed. These rivers flood contributed by ± 25% of the Ciliwung watershed resulting in widespread inundation in Jakarta increases. One of the efforts to control flooding in Jakarta is the construction of weirs Katulampa which serves as an early information system to flooding Ciliwung will enter Jakarta. From the evaluation of the function obtained Katulampa weir water level to Alert 1 is 200-250 cm to estimate flood discharge using HEC-HMS at 733 m3 / s. Data on the water level in the dam Katulampa estimates that approximately 9-10 hours later flood will arrive in Jakarta. The ability of the dam to divert water when it reaches Alert 1 of 7% of the flood discharge through the doors retrieval. In order to optimize the function of the weir and re-plan the weir, the initial step is the hydrological analysis with the result that be discovered gauge the dependable discharge, needs water discharge and flood discharge. In the Katulampa weir planning dependable discharge used is the discharge with probability 80%. Water needs value to fulfill the irrigation water requirement is 1.87 liters / sec / ha or water needs discharge for water irrigation is 6.03 m3 / sec. Flood discharge by the method of HEC-HMS for the return period of 25 years at 733.90 m3 / sec is used as the basis to design the main building weirs. Katulampa weir using high lighthouse beacon round with effective width of 2.5 m and 95.43 m. Bags of mud along the channel with a width of 62.5 m at 4.75 m channel basis. Katulampa weir construction planned at a cost of ±4,193,000,000.00 billion rupiah, and planned implementation time ± 168 working days.

The aim of this activity is to describe the teaching of TRI NGA (Understanding, Ngrasa, Nglakoni) students in developing creative values through the Strengthening the Integrated Pancasila Student Profile (P5) Project with SBDP content at SDN 3 KTWN. The subjects of this activity were 22 class IV students at SDN 3 KTWN for the 2022-2023 academic year, consisting of 10 male students and 12 female students. ˚This empowerment activity uses the phenomenological method, namely a community service method that describes phenomena that occur in the field in a real and concrete way through data mining using observation, questionnaires, interviews and documentation techniques. The instruments used in this research were observation sheets, questionnaires, lists of questions, and activity documentation. The data analysis technique in this presentation is carried out using qualitative descriptive techniques referring to the Miles and Huberman analysis technique which consists of the stages of data collection, data reduction, data presentation and drawing conclusions. Project activities are carried out in five stages, namely 1) Introducing students to plastic, 2) Analyzing the conditions of the surrounding environment, 4) Analyzing the dangers of plastic waste, 3) Real action: how to overcome the plastic problem, 5) Work Title P5. The research results show that Tamansiswa TRI NGA teaching is able to develop students' creative values through the Pancasila Student Profile Strengthening Project (P5) which integrates SBDP content in class IV of SDN 3 KTWN
