ABSTRACTWay Kambas National Park (TNWK) is one of the conservation areas in Lampung Province. The National Park functions to protect, preserve various kinds of animals and conservation. Design based on Eco-Technology is an absolute requirement for the sustainability of the region. This study aims to plan Eco-Technology-based drainage from road construction in the Sumatra Rhino Sanctuary (SRS), Way Kambas National Park, with snake objects. Every infrastructure development, such as drainage, must pay attention to the lives of wild animals such as snakes. Planning starts with calculating hydrological analysis to produce a debit plan with a rational method. Analysis of snake migration is done to determine the behavior and migration of snakes. Based on the calculation results there is no flood point from the planning of cross-section D1-D8 with the width of the channel width (b) = 20 cm, water depth (h) = 14.47 cm, peak width (B) = 220 cm, cross-section = 10Ã‚Â°Ã‚Â and cross-section material used is soil. With the drainage concept, the migration of snakes from one span to another is not disturbed to maintain the balance of the natural ecosystem. The conclusion is that the drainage design obtained is getting sloping, so the drainage conditions are better and friendly to snakes.Keywords: Eco-Technology, drainage, conservation, Way Kambas National Park, snake migrationABSTRAKTaman Nasional Way Kambas (TNWK) merupakan satu diantara kawasan konservasi yang berada di Provinsi Lampung.

Abstract Indonesia has a vast coastal area and is very potential to be developed, one of which is in tourism. In the Lampung area itself, tourism activities are industries that are growing very rapidly. One of them is in South Lampung Regency, which is now starting to emerge new tourist attractions but still not well managed by the government or the local community. One of them is Sekepal Island which is a new tourist destination in South Lampung Regency. This destination is developed and managed independently by the local community. The purpose of this study was to analyze the suitability of coral reef ecotourism in the development of tourism in South Lampung Regency. This study uses the Tourism Completeness Index by Yulianda (2007). Data collection is done by observation, documentation. The scores obtained are then matched with assessment points so that the value of suitability from ecotourism can be obtained. The results of the study show that the coral reef suitability index, including the category, is quite suitable and can be developed in its potential. But in development also must involve the role of the community and the government to run perfectly. Based on the matter, the researchers suggested to the community, especially Totoharjo Village, to involve the Lampung Regency Tourism Office to develop coral reef ecosystems in the future. Then the suggestion for further research is that researchers are advised to conduct more in-depth research into all ecosystems in coastal areas, such as mangroves and coral reefs, and to involve more leaders in their fields in conducting future research.

Mangrove ecosystem existence is important for environment and other organisms because of its ecological and economical values, so that management and preservation of mangrove ecosystem are needed. The purpose of this research was to determine the existing condition of mangrove, both its distribution and its functional transformation in Indah Kapuk Coastal Area. Avicennia marina becomes important as wave attenuation, a form of abrasion antidote. Transect-Square and Spot-Check methods were used to determine the existing condition of A.marina mangrove forests. Autocad program, coordinate converter, Google Earth, Google Map, and Arc View were applied in process of making mangrove distribution map. In western of research location exactly at Station 1 and Station 2, the density value of mangrove was 450 and 825 tree ha-1, respectively with sparse category because they were contaminated by waste and litter. In eastern of research location namely Station 3, Station 4, and Station 5 the mangroves grow well with density value of 650 (sparse), 1,500 (very dense), and 1,200 tree ha-1 (fair), respectively, eventhough the contamination still happened. The mangrove forests around the stations do not function as wave attenuation because there were many waterfront constructions which have replaced the function of mangrove forests to damp the wave. In short, it can be stated that the mangrove's function has changed in a case of wave attenuation. The function of mangrove forests is not determined by mangrove forest density but it is determined by mangrove's free position.

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.

Water problems consist of three types: flood, drought, and water pollution. Floods are recognized as a significant source of threat to human life. One of the flood prevention actions that can be done is to optimize the drainage channels. Drainage can be defined as a technical action to reduce excess water so that the function of the area or land is not disturbed. University of Lampung is one of the locations prone to flooding. Therefore, a research to overcome the flood that occurred at the University of Lampung has been conducted (Case Study: Zone III Rectorate Area - Faculty of Agriculture). The purposes of this research are to analyze the drainage system of University of Lampung and to design drainage system that fulfill flood discharge plan. The research was conducted by survey in the field. The analysis conducted in this study include hydrological analysis and hydraulics analysis using HEC-RAS4.1.0 application. Calculation of discharge plan using rational method.. Based on the analysis results, there are no channels that are not sufficient for flood discharge, but there are some channels that are disconnected and cause the water to not flow. The disconnected channels are located on the channel with the DN5 and DN62 codes. For that, it is recommended to create a channel connecting DN62 channel with DN63, and make a channel on channel DN5 to DN65. The budget required for the repair of this channel is Rp 207,203,725.00 (Two Hundred Seven Million Two Hundred and Three Thousand Seven Hundred Twenty Five Rupiah).Keywords: Drainage, HEC-RAS, hydrology, hydraulics, floods
