Analyzing these lines one sample content and its concentration could be determined and the analysis is known as Quantitative Spectrographic Analysis. The Quantitative Spectrographic Analysis is carried out in 3 steps, as follows. This consists of gauging a photographic emulsion, to determine the intensity variations in terms of the incident radiation. For the procedure of emulsion calibration an adjustment with square minimum to the data obtained is applied to obtain a graph.

It is possible to determine the density of dark spectral line against the incident light intensity shown by the microphotometer. The values of known concentration of an element against incident light intensity are plotted.

Since the sample contains several elements, it is necessary to find a work curve for each one of them. The calibration curve and hentik curves are compared and the concentration of the studied element is determined.

Directory of Open Access Journals Sweden. Data ini kemudian diproses dengan analisa deskriptif dan analisis regresi. Hasil analisis menunjukkan bahwa tingkat partisipasi masyarakat cukup tinggi. Tingginya tingkat partisipasi ini disebabkan karena kebutuhan komunitas yang tinggi akan pelayanan air. Meskipun demikian masyarakat merasakan pentingnya peningkatan pengelolaaut air oleh UPS-AB khususnya dalam hal: ABSTRACT Polluted river water due to destructed forest, mining and population settlement have created lower quality of up-stream water that households generally consume.

Considering the scarcity of waterinPotable Water Management Unit UPS-AB of Kumpai Batu was founded as community association to participate in the potable water preparation, development and maintenance.

This study was conducted through a field survey on households selected using random sampling method. The variable studied were the availability of UPS-AB, involvement indecision making, involvement in activity, involvement in evaluation and social economic condition of village community.

Data were processed using descriptive an regression analysis. The result showed that availability of UPS-AB involvement in decision making, involvement in activities, involvement in evaluation and social-economic condition of village community positively affected community participation in potable water management. Full Text Available The exploration and production process of oil and its supporting operations always generates waste as by-product.

If they are uncontrolled, it might decrease the environmental quality. Thus, it is necessary to manage and treat the waste in order to meet the regulation standard of quality and quantity. PT XYZ is an energy company, particularly oil and gas production, which its production activity generate a large amount of waste as well as produced water.

Thus, PT XYZ must have facilities or produced water handling plant which could minimize pollution caused by produced water. PT XYZ already has a system of produced water handling with recycling principle. After oil and water separation including water treating at Water Treating Plant WTP, produced water will be used for steam injection.

This is the part of enhanced oil recovery by steam flooding in Duri Field. If the produced water and brine water is over load the capacity of oil enhanced recovery injection, it might be disposed through injection to Disposal Well and there are certain condition that produced water should be discharged into canal.

Water Treating Plant is a facility for treating produced water. Full Text Available Abstrak — Optimasi penggunaan energi matahari perlu ditingkatkan, salah satunya dengan menggunakan kolektor surya.

Namun masuknya air water ingress ke dalam teras reaktor akibat pecahnya tabung penukar panas generator uap, yang dikenal sebagai salah satu kecelakaan dasar desain, dapat mengintroduksi reaktivitas positif dengan potensi bahaya lainnya seperti korosi grafit nyamk kerusakan material struktur reflektor.

Hasil perhitungan memperlihatkan koefisien reaktivitas Doppler tetap negatif untuk seluruh opsi bahan bakar yang dipertimbangkan bahkan untuk posibilitas water ingress yang besar. Efek water cirri-ciri lebih kuat pada model kisi dengan fraksi packing lebih rendah karena lebih banyak volume yang tersedia untuk air yang memasuki teras reaktor. Efek water ingress juga lebih kuat di teras uranium dibandingkan teras thorium dan plutonium sebagai konsekuensi dari fenomena Doppler dimana absorpsi neutron di daerah resonansi U lebih besar daripada Th dan Pu.
