Abstract

Weather observations can be done in two ways, namely weather observations based on weather stations and based on remote sensing such as satellites. One of these weather study data is rainfall measured from the BMKG rain observation post and TRMM satellite observations. To see the pattern of the distribution of rain that has occurred, the two weather observations can be connected as a reference for the distribution of rain. The purpose of this study was to analyze the correlation value of rainfall data between BMKG and TRMM by looking at the comparison graph and analyzing the comparison of statistical parameters. This research was conducted using daily rainfall data from 1998-2018 at four rain stations in West Java Province and taking descriptive decisions in the form of pictures and graphs in the form of daily, monthly and annual data. Based on the analysis results, the largest correlation value is in the annual cumulative with a value of 0,88-0,94, the smaller the number of days, the smaller the correlation value. The BMKG and TRMM rainfall data have relatively the same pattern, but the maximum data have differences so that it reduces the correlation value. In the Statistical Parameter analysis, it can be stated that the difference in the values ??of the statistical parameters is directly proportional to the daily cumulative, that the difference in the median and mean values ??in the BMKG and TRMM data is greater in the data with a larger cumulative. Meanwhile, for linear regression analysis, it was found that the greatest value was the cumulative 1-year value with a coefficient of determination from 0,78 - 0,89.

Abstract

Taman Pendidikan Al-Qur’an (TPQ) Darrul Islam terletak di Dusun Sindangsari, Desa Natar, Kabupaten Lampung Selatan. TPQ ini memiliki siswa sejumlah lebih dari 100 orang, dengan pendidikan formal dari SD hingga SMA. Dengan jumlah siswa yang banyak yang membutuhkan air untuk bersuci dan sanitasi maka kebutuhan air menjadi sangat tinggi. Akan tetapi ketersedian air yang ada tidak mampu memenuhi kebutuhan air yang tinggi. Selain masalah keterbatasan air bersih, masalah yang dijumpai adalah kurangnya kegiatan kreatif yang dapat dilakukan untuk mengalihkan ketidaktertiban siswa ketika menunggu pelajaran dimulai. Untuk mengatasi masalah yang dijelaskan di atas, maka solusi yang ditawarkan adalah pemanfaatan air langit (air hujan) melalui sistem Pemanenan Air Hujan (PAH) yang dapat digunakan untuk memenuhi kebutuhan air akan sanitasi dan bersuci sekaligus dimanfaatkan untuk pengairan tanaman hidroponik yang dikelola oleh TPQ dengan melibatkan siswa. Sehingga siswa akan disibukkan dengan kegiatan kreatif pemeliharaan tanaman hidroponik dan tidak ada waktu lagi untuk melakukan keisengan. Penerapan PAH di TPQ Darrul Islam menjadikan TPQ ini menjadi pelopor konservasi air dan peduli lingkungan bagi masyarakat sekitar dan siswa TPQ. Kata kunci: Hidroponik, Pemanenan Air Hujan, TPQ

Abstract

Dam and irrigation channels are utilized to supply irrigation in Way Jepara area. Way Jeparacannot optimally function because the catchment area is disturbed by illegal logging which mayincrease erosion rate as well as sedimentation to the dam. This research aims to analyze erosionwhich occurs in the catchment area and sedimentation in the dam. Erosion prediction model usedin this study is USLE (Universal Soil Loss Equation). From the analysis it is obtained that totalerosion (A) in the catchment area is 2307.01 ton/year or 156.41 ton/ha/year which is classified aserosion class III or medium. The highest erosion rate, 1552.63 ton/ha/year, occurs in Land UnitNo. 107 near Langkap Mountain which is classified as severe. From the analysis the problemsarose can be categorized into two groups, problem related to catchment area conservation andtechnical l problem directly related to the dam. Solution to the problems should be based onconservation as well as social welfare.

Abstract

Nagara River is a river in South Kalimantan province with extensive swamp area which formsseasonal flood plain and protects downstream area from flooding and salt water intrusion. Theplan for land use change from the swamp area to plantation area involves building dyke on thesides of Nagara River. This research aims to analyze the elevation of Nagara River duringflooding when the swamp area is occupied as an extension of flood plain, compared that resultedfrom the scenario when this area is converted into plantation area which needs dyke on the sidesof the river for flood protection. There are two kinds of scenarios, first only one side of the riverwhich will be build dyke, and second both sides of the river will be built dykes. The analysisinvolved rainfall data analysis using daily module rainfall, design discharge analysis usingRational Method and hydraulic analysis using HEC-RAS software with one-dimensional steadyflow. The result shows that using dyke at elevation +11.00 m, the increase of water level is notsignificant while one side of the river is protected by dyke. An increase of 30 cm of water elevationis obtained using scenario of both sides are protected by dykes. The increase of water level maycause flooding in the area located at the upstream and downstream of the plantation area.

Abstract

A series of floods occurred in several places in Malaysia during December 2006 – January 2007,including the southern state of Malaysia; Johor Bahru. The rain recorded in the city of JohorBahru was 286 mm. To understand this phenomenon and to investigate the design flood of thisregion, a hydrology analysis procedure was taken into account. The hydrology analysis procedureincludes collecting rainfall data, analyzing rainfall data including areal rainfall and rainfallfrequency, developing synthetic unit hydrograph using SUH GAMA I. It is noticed that the lengthof rainfall data collected, i.e. 60 years, is sufficiently long for analysis. From the hydrologyanalysis done in this study, it can be concluded that the rain fell during 2006-2007 flood eventshad nearly 100 years period of rainfall. And the prediction for 100 years period of flood is 16,962m3/s.

Abstract

Way Besai River's catchment area is used as agricultural, tourism, and hydroelectrica power plant (PLTA) purposes. PLTA Way Besai was built for generating electrical power using the height of a waterfall from Way Besai River, however nowadays PLTA Way Besai is having a decrease of electrical power because of the now happening drought. The power decrease reached until 40 MW while it used to have 90 MW power supply causing only a rough 50 MW energy power left to be operated. The metode that is used in estimating the value of sediment discharge is by using the Universal Soil Loss Equation (USLE) method and Measured Sediment Analysis. From the analysis results, the overall value of sediment was attained by merging the value of suspended load and bed load which is 170528,443 m 3 /year. The value of seddiment that is attained from USLE methode is 105520,738 m 3 /year.

Abstract

Water resources in Western Lampung Regency particularly the sub-District Suoh has a lot of po- tential hydropower, which have not been able to optimally utilized as electrical energy. So that one of the optimal effort that can be done is by using microhydro energy. Location of the research is in the Way Sekanda river tributary of the Way Semaka river. Process analysis using primary data in the form of a cross section of the river cross-section of data and flow velocity of Way Sekanda, than secondary data from hourly discharge data from the watershed outlet Way Besai for 11 (eleven) years, the real-time of rainfall in Tugu Ratu village from Septem- ber 2012 to September 2014 and watershed area derived from Geographic Information System. Analysis starts from the formation of spatial data maps of Way Semaka watershed, Way Besai wa- tershed and Way Sekanda watershed using ArcGIS program. Research method includes regional- ization Way Semaka watershed and Way Besai watershed, estimation the dependable discharge (Q 80% ) using FDC method, measured discharge calculation of Way Sekanda river, correlation be- tween discharge FDC method and measured discharge and calculate the electric power which can be generated. The formation of the watersheds were done using spatial data analysis and were found that the area of Way Semaka watershed is 731,0783 km 2 , Way Besai watershed is 415,0393 km 2 , Way Sekanda watershed is 1,48 km 2 . Using measured discharge recorded in Way Besai watershed and the application of regionalization method, the discharge at Way Semaka and Way Sekanda can be estimated.This is evidenced by the amount of discharge calculated by the method of Flow Dur- ration Curve is not much different from the magnitude of the discharge measured in the field. Q80 % with FDC method (Flow Duration Curve) to Way Sekanda River is 0,0312 (m 3 /sec), while the measured discharge in location of Way Sekanda micro hydro power plants (MHP) 0,0314 (m 3 /sec). From the calculation of the electric power in Way Sekanda by using dependable of dis- charge 50% (Q 50% ) of 0,0592 m 3 /s it is obtained the electricity power with an efficiency of 60 % is 2,7479 kW, while the electric power with an efficiency of 90 % is 4,1219 kW. Therefore Way Sekanda River is potential for micro hydro power plants (MHP).
