Semarang is a beach city that is potential for sea water intrusion process happened. Correlation to the sustainable development programs in our country especially environment-conservations aspect, it is important to be known, and need to be monitored and controlled.Contamination in land water is a serious probleme, becouse it makes water quality decrease. Sea water intrusion is one of contaminant resources to the land water that cause hight concentration of salt. It is identified by concentration level of chloride (Cl) that come from sea water by mass transportation process of chloride (Cl) to the land water, and so the volume of land water that is fullfill in quality standard limited. Focus of the research is identifying distributions of factor that cause sea water intrusions happened to the land water in inner aquifer in Semarang area. Method of research, by determining of monitoring wells of ESDM service as sample points, continued to measuring concentrations of chloride (Cl) continuously and identifies factor causes the intrusions. To describe the distributions is used the ArcGIS application programs, and to know correlations of chloride’s concentrations to time changes is used correlations statistics test. The result of research showed that sea water intrusions which are identified the chloride (Cl) concentrations and exceeded the quality standard (PERMENKES No. 492/MENKES/PER/IV/2010), in 1992 only one of them, that is monitory wells on STM Perkapalan, north of Semarang. And in 2013, the intrusions happened in 6 (six) areas, those are monitory wells on STM Perkapalan, PRPP, Pelabuhan Tanjung Mas, Simpang Lima, PT Panca Jaya and LIK Kaligawe located in areas of : Kecamatan west of Semarang, nort of Semarang, middle of Semarang and Gayamsari. Factors which cause sea water intrusions are : the increase of populations effects the water reserve decreases to be about 125,7 .106 m3, Land water head changes that caused by descending (sinking) of land , changings of land water surface level from sea level make the distributions of intrusion go to short -east direction, and there is correlation between Chloride’s concentrations level changes to the times changes by the constant of correlations about R = 0,704 to R = 0,997.

The Epanet model in clean water pipelines is intended for time efficiency in calculating hydraulic behaviour. Calibration of the water pipe network is to compare the simulation results of the model to actual field observations and to see that the model that has been made is truly valid and reliable as a tool to determine the hydraulic behaviour of the network system when a change input into the system is given (e.g. the addition of pipelines and number of customer tapping debits). The pipe roughness coefficient (C) is a number that indicates the amount of energy loss due to friction between the flowing fluid and the pipe wall. The increasing age of the pipe will cause the pipe wall roughness to increase, and the energy loss will be even more significant. This research aims to calibrate the pipe network model by adjusting the C value of the actual pipe roughness coefficient according to the installed age. An initial simulation model was carried out by entering the standard pipe C value in the Hazen Williams energy loss equation in the Epanet link/pipe properties. Then a simulation is carried out by modifying the value of C according to the pipe's service life. For 600 mm steel pipe, change the C value from 150 to 87 (pipe age >30 years), HDPE 315 mm pipe changes in C value from 140 to 100 (pipe age >10 years) and 25-50 mm PVC pipe from 140 to 100 (pipe age >10 years). From the simulation results of the Epanet model-field observations, the average compressive height was obtained for five observation nodes.of 2 tails was performed paired sample test the pressure height value of the model-observation. Before modifying the value of C, the paired mean difference test results showed a significant difference between the simulation results of the model on field observations with a model significance value of 0.004, which means <0.005. There is a considerable difference between the simulations and observations, and the model is considered invalid. However, after modifying the value of C according to the actual age of the pipe, a paired sample test T average value of the compression model-observation was 0.098 > 0.005), which means that there is no significant difference between the simulation and observation. This means that the model made is quite valid. Product moment correlation between the model simulation height - field observations, the value of R = 0.967, the relationship is robust between the two results.

Proyek Pembangunan Bendungan Karian merupakan salah satu proyek strategis nasional yang dilaksanakan sejak tahun 2015, memiliki tiga fungsi utama yaitu penyediaan air Rumah Tangga, Kota dan Industri (RKI) untuk Provinsi Banten dan DKI Jakarta, suplesi Daerah Irigasi Ciujung dan pengendalian banjir. Daerah Aliran Sungai Ciberang Kabupaten Lebak sebagai lokasi pembangunan Bendungan Karian mengalami bencana banjir bandang pada Januari 2020, akibat dari pengaruh cuaca ekstrim sebagai salah satu penyebabnya (Yahya, 2020). Hal ini mengakibatkan terputusnya jembatan konstruksi pada outlet terowongan pengelak. Pelaksanaan pembangunan Bendungan Karian direncanakan selesai pada tahun 2019 namun masih berlangsung hingga kini, mengacu kepada kajian ulang dokumen desain pada tahun 2015. Penelitian ini bertujuan untuk mengkaji ulang desain hidrologis bangunan pengelak/cofferdam hulu Bendungan Karian berdasar data hujan terbaru pada DAS Ciberang. Pemodelan dilakukan dengan menggunakan perangkat lunak HEC-HMS yang memiliki kemampuan untuk melakukan penelusuran banjir pada suatu Daerah Aliran Sungai (DAS). Hasil analisis terjadi peningkatan curah hujan rencana pada DAS Ciberang untuk kala ulang 25 tahun dari 180 mm/hari menjadi 210 mm/hari, dan debit banjir rencana dari 664 m3/detik menjadi 793.2 m3/detik, berturut-turut berdasar data periode 1982-2015 dan periode 1982-2019. Semua perubahan data tersebut masih sesuai dengan banjir desain yang digunakan pada desain cofferdam hulu Bendungan Karian Tahun 2015 Sehingga secara aspek hidrologis cofferdam hulu sebagai bagian pengaman pekerjaan konstruksi timbunan bendungan utama pada Bendungan Karian masih memenuhi kriteria desain awal atau aman walau telah terjadi perbedaan 5 tahun data hujan pada DAS Ciberang.

Data availability of on a river discharge is the key to waterworks planning. Unfortunately, not all rivers have long and complete historical data records to support the planning. Therefore, a hydrological model capable of predicting long-term river discharge is needed. There are many hydrologic models that have been developed, ranging from the simplest ones by using empirical black-box model, to complex ones with physical white-box model. This study used ANN application due to its data requirement that is applicable to be met in study area, Sekayam River, a part of Kapuas Subwatershed, namely Kembayan Watershed. Although the available data is relatively minimal, which is only rainfall and evaporation data, the ANN application can predict river discharge that is close to the measurement in the field, with a mean square error (MSE) of 0.25. The results show that ANN application was able to predict river discharge reasonably with climate and rainfall data as the input. Deviation may occur due the broad scope of the research area, Kembayan Watershed, a Kapuas Subwatershed which amounted to 2,290 km2.
