ABSTRAK Waduk Jatibarang merupakan salah satu waduk yang memiliki peran penting di Kota Semarang sehingga kualitas perairannya perlu diperhatikan. Keberadaan fitoplankton di perairan berkaitan erat dengan kesuburan dan kualitas suatu perairan dikarenakan fitoplankton berperan sebagai produsen primer. Tujuan penelitian ini untuk mengetahui kualitas perairan berdasarkan kelimpahan fitoplankton serta melihat sejauh mana korelasi nitrat dan fosfat akan mempengaruhi kelimpahan fitoplankton diperairan. Penelitian dilakukan pada tanggal 27 Maret 2019 di Waduk Jatibarang semarang. Pengambilan sampel dilakukan menggunakan metode purposive sampling di tujuh stasiun dengan tiga titik kedalaman (permukaan, tengah dan dasar perairan) dan tiga pengulangan (pagi, siang dan malam). Pengolahan data menggunakan program SPSS 25 dengan analisis regresi liner berganda. Konsentrasi nitrat yang didapatkan berkisar antara 0,45-9,64 mg/l, konsentrasi fosfat berkisar antara 1,26-4,81 mg/l, kelimpahan fitoplankton berkisar antara 1.667 – 275.833 ind/l. Hubungan antara konsentrasi nitrat dan fosfat dengan kelimpahan fitoplankton tergolong lemah dengan koefisien korelasi (r = 0,378). Nitrat dan fosfat mempengaruhi kelimpahan fitoplankton sebesar 15% dengan koefisien determinasi (r square = 0,150). Tingkat kesuburan di Waduk Jatibarang termasuk dalam kategori mesotrofik hingga eutrofik berdasarkan konsentrasi nitrat, fosfat dan kelimpahan fitoplankton. ABSTRACT Jatibarang Reservoir is one of the reservoirs that has an important role in the city of Semarang so that the quality of its waters needs to be considered. The presence of phytoplankton in waters is closely related to the fertility and quality of a waters because phytoplankton act as primary producers. The purposes of this research are to determine the quality of water based on the consentration of nitrate and phosphate, to calculate the abundance of phytoplankton and also to know the correlation of nitrates and phosphate toward the abundance of phytoplankton. The research was conducted on 27 March 2019 in Jatibarang Reservoir Semarang. Sampling was carried out at seven stations with three depth points (surface, middle and bottom) and three repetitions (morning, day and night). Data processing using SPSS 25 programme with multiple liner regression analysis. The concentration of nitrate gained ranged from 0.45 - 9.64 mg/l, phosphate concentrations ranged from 1.26 - 4.81 mg/l, the abundance of phytoplankton ranges between 1,667 – 275,833 ind/l. The relationship between nitrate and phosphate concentrations with an abundance of phytoplankton is relatively weak with a correlation coefficient (r = 0.378). Nitrates and phosphates affect the abundance of phytoplankton by 15% with coefficient of determination (r square = 0.150). Water’s trophic state in the Jatibarang reservoir belongs to the mesotrophic up to Eutrophic category.

The article investigates the causes, essence, and peculiarities of corruption and the shadow economy, as well as how they are related, in Ukraine in comparison with other Central and Eastern European countries. A correlation‑regression analysis of statistical data revealed a direct correlation connection of different strengths and statistical significance between levels of corruption and the shadow economy in all Central and Eastern European countries. However, the degree to which corruption impacts the variation in the levels of the shadow economy differs significantly in countries across the region. The key conclusion is that in countries with relatively high levels of corruption and the shadow economy, corruption causes a smaller share of the shadow economy than in countries with relatively low levels of these phenomena. Causes of the weak correlation between levels of corruption and the shadow economy in Ukraine were identified. The main corruption and non‑corruption factors of Ukraine’s economy shadowing were determined. It was concluded that policy and measures to counteract corruption and the shadow economy in Ukraine should be aimed at eliminating their root causes rather than manifestations.

Identify the relationship between the aerodynamic loads , weight of the wing structure and its deformations is an important issue in the early stages of the design of transport category aircraft.Existing methods of the weight analysis allow to estimate weight of basic elements of the plane (a wing, a fuselage, plumage, the chassis, wing mechanisation), but forecasting of distribution of these weights along their basic axes is a special problem.The work purpose is working out of a way of forecasting of running weight of a design and fuel distribution on tanks on a wing of the plane of a transport category at stages of outline designing.When determining the load of the weight of the wing structure input data are concentrated and distributed weight values that are determined by special methods of calculation. Insufficient accuracy of distribution of mass loadings can lead to unreasonable surpluses or lacks of durability of a design. Overestimate of weight of a design of a wing increases effect of unloading from own weight that reduces size of settlement weight. Understatement of the wing reduces weight and unloading heavier its design. Using regression analysis methods for processing of statistical data on the aircraft weight peers increases the accuracy of calculations.

The concept of regression was first introduced by Sir Francis Galton in the context of inheritance of stature. Karl Pearson found the regression of son’s height on father’s height to be a biometrical fact. Soon the use of regression technique became too common for a variety of problems. The relationship between variables, if it exists, may be linear or curvilinear. In this chapter, a detailed discussion of linear regression is carried out. The regression analysis is an important statistical tool to find the relationship between different variables that can also be applied to the field of governance.
