Abstract Analysis is a way to check the availability and irrigation water requirements in an agricultural land. For the purposes of irrigation, enough water is needed to increase agricultural productivity. Performance management of irrigation water at farm level is very varied with irrigation water allocation is less efficient. It is thus this is one major cause actual yields are still low. Then need to arrange for water use and preparation of schedules and appropriate cropping pattern under various conditions. So that would be more effective in using water, expected in the future no water shortage, which in turn will increase productivity pertanian.Yang ultimately to meet national food needs. The research shows that it turns out the availability of water in the reservoir Cipancuh insufficient irrigation water requirements. Keywords : rainfall, dependable flow, cropping patterns and crop species.

Abstract

ABSTRACT Produced pretty much every day of domestic wastewater from settlements , especially eating and drinking activities conducted by residents ranging from morning till night . Type of waste , waste volume and intensity of the waste will pollute the environment if the waste is discharged directly into the exhaust duct without any prior processing . Plus the process waste water discharges directly to the exhaust duct has been running long enough to worry about adding soil saturation liquid contaminants that would add to pollution such as odor or stench . This research will try to analyze the data from the laboratory test results of waste water from the fish pond and try to analyze if done trickling filter wastewater treatment . Keywords : effectiveness , waste water treatment, trackling filter ABSTRAK Setiap harinya dihasilkan cukup banyak limbah cair domestik yang berasal dari permukiman terutama aktivitas makan dan minum yang dilakukan oleh para penghuni mulai dari pagi hari hingga malam hari. Jenis limbah, volume limbah dan intensitas limbah akan mencemari lingkungan jika limbah tersebut dialirkan langsung ke saluran pembuang tanpa ada proses pengolahan terlebih dahulu. Ditambah lagi proses pembuangan limbah cair secara langsung ke saluran pembuang sudah berjalan cukup lama dikhawatirkan menambah kejenuhan tanah terhadap cairan pencemar yang akan menambah pencemaran lain seperti bau tidak sedap atau bau busuk. Penelitian ini akan mencoba menganalisis data hasil pengujian laboratorium dari limbah cair yang berasal dari kolam ikan dan mencoba menganalisisnya jika dilakukan pengolahan limbah secara trickling filter. Kata kunci: efektivitas, pengolahan limbah cair, trackling filter.

Abstract

Abstract Network is a diagram illustrating the relationship of dependence between the parts and the activities used to solve complex mathematical problems to make it more simple and easily observed . Analysis on the network can be done by using appropriate calculation procedures in the operations research methods to produce a system of decision making based on the results of the optimization calculations . Special problems that utilizes network analysis optimization problem of which this is the special problems associated with project management . Network model is a particular model of linear modeling . Network optimization problems with many variables and constraint functions manually can not be done with manually calculation . They need to be calculated with a computer . One of the software associated with the calculation processing network optimization problems is Excel Solver . Excel Solver is software can be installed from MS Excel , which generally already owned by each computer . The focus of the study was to investigate the application of network optimization methods on project management and process the programs to excel solver . Keywords: optimization , network , Excel Solver . Abstrak Jaringan kerja (network) adalah suatu diagram yang menggambarkan hubungan ketergantungan antara bagian-bagian kegiatan dan digunakan untuk membantu menyelesaikan masalah matematika yang cukup rumit agar menjadi lebih sederhana dan mudah diamati. Analisis pada jaringan kerja tersebut dapat dilakukan dengan menggunakan prosedur perhitungan sesuai metode pada riset operasi untuk menghasilkan suatu sistem pengambilan keputusan berdasarkan hasil perhitungan optimasi. Permasalahan khusus yang memanfaatkan persoalan optimasi analisis jaringan kerja ini diantaranya adalah permasalahan khusus terkait dengan manajemen proyek. Model jaringan kerja merupakan model khusus dari pemodelan linier. Untuk permasalahan optimasi jaringan kerja dengan banyak variabel dan fungsi kendala maka penyelesaian secara manual tidak lagi memungkinkan sehingga perlu dihitung dengan komputer. Salah satu software yang terkait dengan pengolahan perhitungan permasalahan optimasi jaringan kerja adalah Excel Solver. Kelebihan Excel Solver dibanding software lainnya adalah karena software ini dapat diinstall dari MS Excel yang pada umumnya sudah dimiliki oleh setiap komputer. Fokus penelitian adalah meneliti penerapan metode optimasi jaringan kerja pada manajemen proyek dan pengolahan program serta datanya dengan excel solver. Kata Kunci: optimasi, jaringan kerja, Excel Solver
