Self compacting concrete is that can utilize its own weight to be able to flow to fill the room without any compaction process at all. The purpose of this study was to determine the compressive strength of self-compacting concrete with the substitution of rubber seeds as coarse aggregate. The method used in this study is an experimental method (experimental), also discusses the distribution of Slump Flow with the use of rubber seeds, the rate of use of rubber seeds is 3%, 4% and 5% of the weight of the coarse aggregate (split) used. The results of this study indicate the optimum compressive strength at the age of 28 days of concrete with the highest value in code A which is 8.93 MPa with a specific gravity of 2.33 grams/cm³ and a Slump Flow value of 52 cm. From this research, it can be concluded that the less mixing of rubber seeds in concrete composition the higher the compressive strength and the lower the specific gravity, while the Slump Flow value obtained will be lower. Due to the brittle nature of the rubber seeds, the slippery surface of the rubber seeds and the lightweight rubber seeds.
自密实混凝土是可以利用自身的重量，能够流动，以填补房间没有任何压实过程。本研究的目的是确定橡胶种子代替粗骨料的自密实混凝土的抗压强度。本研究采用的方法是实验法(experimental)，也讨论了坍落度流的分布与橡胶籽的使用，橡胶籽的使用比例分别为重量的3%、4%和5%的粗骨料(劈裂)的使用。研究结果表明，混凝土龄期28天的最佳抗压强度在规范A中最高，为8.93 MPa，比重为2.33 g /cm³，坍落度流值为52 cm。通过本研究可知，橡胶籽在混凝土成分中的掺入量越少，混凝土抗压强度越高，比重越低，得到的坍落度流值越低。由于橡胶籽的易碎性，橡胶籽表面光滑，橡胶籽重量轻。

Watershed section upstream is often the focus of watershed management planning because in addition to its, as acatchment, there are alsonbiophsical links to downstream areas. This study aims to determine the level of erosion and sedimentation in Air Betung sub-watershed. Erosion and sedimentation analysis used the formula USLE (Universal Soil Loss Equation) which was influenced by faktors such as, rain erosion index (R), soil erodibility index (K), slope length and slop (LS), management factor values safe and assement of land coversation factors (CP). Based on the result of the analysis with using the USLE method and approached with ILWIS 3.3 showed that value erosion was 54,565.73 tons/ha/year. From the results of measurements in the large sediment field hovering that occured in Betung sub-watershed was 1.26 grams in 2L water with debit 5.25m3/sec
