Abstract Although in 2019 the local government of Tegal city Indonesia had constructed a retention basin at drainage system of Siwatu, Tegal Barat, Tegal city with a catchment area of 226 ha, the areas around the system still experienced flood and inundation. This study belonged to a descriptive qualitative research aimed to evaluate the performances of Siwatu drainage system and Tegalsari retention basin. Data of the study included field data and technical data from institutions. Based on the 15-year rainfall data (2014 – 2018) from Pemali - Comal PSDA Office, Central Java Province, Indonesia, the statistical parameters of Cs: 0.0027, Ck: 1.904, Sd: 15.91, Cv: 0.144 were obtained and so Gumbel method distribution was applied in the study, the return period rainfall of 10 years was 138 mm, the flood discharge for Qr.10 years was 9.63 m3/sec., the addition of long storage was 8×2,50×500 m, and the combination of pump addition was of 1 m3/sec. with the long storage of 8×2.00×500 m. By implementing one of the alternative choices, either flood or inundation could be resolved.

This paper is a result of research concerning hydrological characteristic in the Garang Catchment Area. At present tha catchment area is often facing the problem of flooding in the dense populated area with cause a lot of loos in Semarang City. This research is aimed at studying hydrological harateristic in the Garang Catchment Area. Hydrological data are obtain from direct measurement at the stream gauging stations in the Garang Catchment Area and collected from Balai Hidrologi Office at Pusat Litbang Teknologi Sumber Daya Air in Bandung and from Hydrological Unit of Central Java Province. From this research were known the rainfall depth, their distribution and their return period; runoff coefficient; streamflow volume; dependable flow; flood discharge characteristi; and minimum discharge. From the some occuring flood indicates of the runoff coefficient is about 0.70. The water volume wasted to the sea is about 195 million m3/year. Yearly average of the dependable flow at stream gaunging stations: Garang – Pajangan  is about 2.28 m3/sec; Garang – Patemon is about 0.92 m3/sec and Kreo – Pancur is about 1.26 m3/sec. Yearly mean of annual flood discharge at Garang – Pajangan is about 435 m3/sec. The maximum capacity of river channel is about 485 m3/sec. The flood discharge characteristic are as follows: time of travel of flood is generally one km/hour approximately, rising time is about 3 hours and time of recession is about 6 – 11 hours. The floods, they are generally occur at the night. Flush flood of 1022 m3/sec occured on January 26, 1990 is estimated on 50 year return period, with 15 year return period of rainfall. The range of minimum discharge is about 0.43 – 3.15 m3/sec. The maximum discharge is about 47.2 – 1118 times of the minimum discharge. Design of the dam in Kreo River at Jatibarang and Kripik River at Mundingan, also increasing of the reforestation area in the upstream catchment are an alternative to reduce the Garang River peak flood.

One of the causes of flooding in Makassar City is the management of the water system that is not optimal. It is necessary to arrange a drainage system to overcome flooding in Makassar City. In this study the topography on Catchment area analysis, analysis of hydrology and hydraulics analysis. Modeling the distribution of flood performed using HEC-RAS applications. This research was conducted in the Tallo watershed which consists of the Upper Tallo sub-watershed and the Mangalarang sub-watershed. The results of the analysis of flood discharge in the Tallo Hilir sub-watershed are 523.76 m3/s and in the Mangalarang sub-watershed are 886.82 m3/s. The flood overflow of the Tallo River spread over 6.48 km2 of Manggala District, 0.31 km2 of Rappocini District, 4.24 km2 of Panakukang District, 3.37 km2 of Tallo District, 11.59 km2 of Tamalanrea District and 0.01 km2 of Biringkanaya District. The total area of flood distribution is 26 km2. The solution to overcome the flooding of the Tallo River with an environmentally sound drainage system, it is necessary to plan the construction of a retention pond in Tamalanrea District, with a normal total storage volume of 2.48 million m3 and a maximum capacity of 5.31 million m3. The construction of this retention pond can reduce 17.7 km2 of flood-affected area.

This study aims to compare Soy Milk and avocado juice giving toward cholesterol rate in children with obesity in State Elementary School 1 and 2 of Katerban, Central Java Province, Indonesia. The study used quasi experiment design with non-equivalent control group framework. Samples of the study were 30 children taken by use purposive sampling. Soy Milk and avocado juice effective to reduce cholesterol level in obesity children (p value=0,000, p<0,05), but neither soy milk and avocado juice there’re no one that more effective to decrease cholesterol level (p value=0,902, p>0,05). 60% of respondent were male student age 11 years (36,7%). Father education were high. Soya milk and avocado juice are able to reduce cholesterol rate. Parents must give attention to children’s dietary intake to reduce cholesterol and obesity, also motivate them to do physical activity.
