Abstract — Coral reefs are coastal marine biota biodiversity. Ketapang beach is one of the tourism destinations in the province of Lampung, therefore there are many activities that can be identified damage to the coral reef at the beach area, so that the necessary steps anticipatory one of them is to transplant corals. The purpose of this service activities 1) Knowing the causes of coral reef degradation in Ketapang Beach, 2) Implement saving coral reefs on the coast of Ketapang, Ketapang District of Pesawaran District. The method is performed in the context of community service are 1) Extension to the public on the importance of coral reef ecosystems, 2) Doing tranplastasi coral fragmentation method using acropora seed. Event followed by several stakeholders from the public and the government. This activity can be concluded: 1) The activities of Ketapang beach tourism indicate damage to coral reefs in the region, it is necessary for coral reef conservation efforts with transplant method. 2) The activity of saving coral reefs done by: transplants used is the fragmentation method. And to preserve the coral reef ecosystem, program outreach to the community is also an effort to prevent the destruction of coral reefs. Keywords — Coral Reef, Tranplantation, Ketapang Beach.

Abstract

Kelurahan Jagabaya III merupakan salah satu kelurahan yang padat penduduknya. Dengan kondisi penampang saluran yang belum sesuai maka diperlukan usaha preventif untuk menghindari luapan air dari drainase yang dapat menimbulkan genangan/banjir. Tujuan dari kefgiatan ini adalah pemanfaatan air hujan demi menghindari kerusakan lingkungan baik dari meluapnya drainase,banjir, dan sebagainya, serta memberikan pengetahuan kepada masyarakat mengenai pentingnya pemanfaatan air hujan dan bagaimana cara menerapkannya dalam kehidupan sehari- hari dalam bentuk kegiatan penyuluhan. Lokasi Penyuluhan Pemanfaatan Air Hujan berlokasi di Balai Kelurahan Jagabaya III, Kecamatan Way Halim. Metode pelaksanaan kegiatan meliputi pengambilan data primer, pengolahan data dengan menggunkaan data curah hujan, dan penyuluhan. Kegiatan penyuluhan tersebut diikuti oleh Pemerintah Setempat dalam hal ini Pegawai serta Lurah Jagabaya III, dan masyarakat sekitar. Pengolahan data dengan memperhitungkan curah hujan harian rerata, koefisien tampungan hujan melalui atap dan menganalisa keksesuaian tampungan dengan curah hujan yang ada. Solusi pemanfaatan air hujan yang sesuai untuk Kelurahan Jagabaya III adalah sistem jaringan air hujan yang ditampung dalam tangki air melalui proses filtrasi kemudian diteruskan ke sumur resapan dan kelebihan air yang tidak terserap akan disalurkan ke dalam saluran pembuangan.

Abstract

The main needs of water for various purposes will continue to increase based on thenumber of people who continue to grow and the development of the rate of developmentsin various sectors. On the other hand, the number of infrastructure delivery of water iscurrently still relatively limited, that hasn’t meet the needs of water. The demandsunavoidable, but shall predictable and planned utilization as well as possible. A trendfrequent are the imbalance between supply and demand for water. To achieve a balancebetween the need for water and availability of water in the future , efforts are required tomeet builders infrastructure raw water community.Domestic water needs for Padang Cermin sub-district is 32,46 l / s and Punduh Pidadasub-district is 10 l / s for 2015. For the next 20 years, the demands for water will be71,18 l/s for Padang Pidada sub-district and 71,18 l/s for Padang Cermin sub-district.The availability of water must meet the size of the high demand for water in order tosatisfy their daily needs. Methods used to acknowledge the number of the availability ofwater is the method by F.J. Mock. The calculation on that available minimum dischargein das way selorejo is 78 l / s and das way curup is 97 l / s.From the calculation on above, the availability and needs water at das way curup anddas way selorejo had a surplus of the availability of water because environmentalconditions in kecamatan punduh pidada and kecamatan padang cermin is in goodcondition.Keywords : Water needs, availability of water, Water Supply Building Materials

Abstract

The calculation is done using the rainfall data obtained from BMKG Kotabumi North Lampung,from 1998 until 2011 with time increment in minutes. The Log Pearson III method is used to findthe design rainfall with return period 2 years, 5 years and 10 years. Then the result isimplemented in the Intensity-duration-frequency (IDF) curves. Time of concentration is linked intothe IDF curves to determine rainfall intensity. Based on the calculated rainfall intensity, thedesign discharge for each return period can be calculated using the rational method.The values of design discharge are then inputted as upstream boundary condition in HEC-RAS.Model output are presented in cross and long section to determine at which return period thedrainage capacity is overflowed. Simulation using HEC-RAS were also done to determine thechannel capacity.Based on the results of this research, it can be concluded that rainfall intensities are 52,6918mm/hour, 65,7820 mm/hour and 75,9032 mm/hour, for 2, 5, an 10 year return period respectively.The capacity of the drainage channel is 2.02 m 3 /hour and is expected to be exceeded on 5 yearsreturn period.Key words : Intensity, Rasioanal method, HEC-RAS, capacity

Abstract

          Water is the source for life. Earth is called the blue planet, as water covers three-quarters of Earth's surface. It's just that most of the sea water (salt water).  Generally, the condition springs in Indonesia experienced a decline in the amount and debit, were damaged in the catchment area and the surrounding environment. To determine the existence of water resources, necessary to identify water resources. This research is to identify the sources of springs in knowing the status of water resources.          The primary data collection is done by identifying the condition of land cover in the catchment area, the condition of the springs, the condition of land cover in a radius of 200 m, the performance of the fountain, the critical level of water catchment areas, the critical level of water catchment areas, the critical level of a radius of 200 m, utilization springs, and the dependence of communities on water resources. While the collection of secondary data obtained from BPLHD Kab. East Lampung in the form of water quality data from 12 springs. Spring Water Quality Analysis using WQI Malaysia with graphic works of Dr. GatotEkoSusilo, S.T., M.Sc.          From the calculations, the average value of the 12 WQI water source is 95.1, meaning that all 12 springs are so richly used by people for drinking, bathing, cooking and others. The 12 water spring in the district of Batang Among them there are 5 springs, in the district of Marga Tiga there are 5 springs, in the District of Sri Bawono there is one source of water, and in District Jabung there is one source of water. Keywords: Water, Water Quality, East Lampung Spring Water, Water            Quality Index Malaysia
