Abstract

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

Abstract

One alternative destination agrotourism in Bali is Agrowisata Pesuteraan alam Sutera Sari Segara located in the village Sibangkaja, District Abiansemal. The agrotourism is a potential to be developed in the world of tourismin Bali. Market segmentation is still dominated by 99 percent students are very massive factor in the development of the market in Bali. The purpose of this study was to determine the diversity of the work done by agrotourism, internal and external factors that influence the development of agrotourism, and alternative development strategies and priorities in agrotourism. Respondents in this study were dividedin to two, namely the respondent's internal and external respondents. Internal respondents were employees of agrotourism taken by census and external respondents that visitors and government who have a relationship with agrotourism. The results of research to get 5 alternative strategies witheach priorityi san alternative way of running the promotion of agrotourism by way of advertising and media selection through brochures, synergy between agrotourism and stakeholders by way of synergy between agrotourism with the private sector, the expansion of market segments using market segmentation way, improving the quality of HR by way of provision of qualified work force, and the quality of agrotourism attractions and silk fabric by settin gquality standards. Suggestions that cangive authors in this study is the use of alternative strategies and priorities that are used to further develop agrotourism. Alternative promotion of agrotourism means of advertising that holds the highest value can be used to developth is agrobusiness. Selection of media for advertising such as brochures media is the most efficient and effective way to convey information to tourists or potential tourists.

Abstract

Air merupakan faktor terpenting, apabila tidak dikelola dengan baik dapat menimbulkan kerugian, salah satunya adalah banjir.  Pencegahan banjir dengan mengoptimalkan saluran drainase. Kegiatan ini bertujuan untuk mereview penelitian terdahulu mengenai peren­canaan drainase, khususnya metode yang dipakai untuk menghitung debit banjir ranca­ngan.  Metode yang digunakan antara lain: Metode Rasional, Weduwen dan Melchior.  Pe­ne­tapan masing masing metode bergantung pada data hujan, karakteristik daerah aliran, dan data debit. Berdasarkan review, penetapan metode untuk menghitung debit banjir rancangan didasarkan pada luas daerah tangkapan airnya.  Lokasi penelitian yang memi­liki luas DAS 0,53 ha sampai 97,34 ha menggunakan Metode Rasional, luas Daerah Aliran Sungai (DAS) 392, 1 ha menggunakan Metode Weduwen, luas DAS 77.088,8 ha meng­gunakan Metode Melchior. Kesimpulannya adalah, perhitungan debit banjir rancangan dengan luas DAS kurang dari 300 ha menggunakan Metode Rasional.Keywords: drainage, flood discharge design, rational method, melchior

Abstract

Water balance can be used as a guide to the presence or absence of water in an area. In the concept of the hydrological cycle that the amount of water in a certain area on the surface of the earth is influenced by the amount of water entering (input) and out (put) in a certain period. Balance input and water output somewhere known as water balance. Since water is dynamic, the water balance value changes from time to time so that somewhere there may be surplus or deficit. If the shortage and excess water is in extreme circumstances can certainly cause disasters, such as floods or drought. The disaster can be prevented or mitigated if good management of the land and the environment is carried out. The water balance is a water balance for agricultural land use in general. This balance sheet is useful in considering the suitability of agricultural land, arranging planting and harvesting schedules, arranging irrigation water supply in the right amount and time. It cannot be denied that some areas of Java and Madura have experienced water shortages, of all the water earth 97.5% is salt water, fresh water is 2.5%.This not entirely surface water and ground water. In Kabupaten Jember, especially in the area of underground water sampling (ABT) conducted by drilling wells in community development projects from the results of this study is expected to help and provide solutions to communities in the study area in the form of water buildings for storage of agricultural water reserves.Keywords:Reviewof Craft Balance
