THE QUALITY DIFFERENCE OF RAW AND DRINKING WATER IN WINTER AND SUMMER IN THE AREA OF THE TOWN OF PETRINJA
No full textČiste pitke vode na Zemlji ima malo, stoga bi glavni zadatak svakog čovjeka trebao biti da nauči štedjeti i što manje zagađivati vodu. O količini dostupne pitke vode ovisi gospodarski razvoj i bogatstvo neke države i njezinih stanovnika. Porastom broja stanovnika na Zemlji smanjuju se dostupne količine pitke vode. Upravo zbog toga ljudi su prisiljeni pronaći nove, bolje i učinkovitije metode pročišćavanja i analiziranja vode, kako se ne bi narušilo zdravlje ljudi. Praktični dio ovog rada se odnosi na kemijske analize vode rijeke Kupe, koja nakon pročišćavanja dospijeva u vodoopskrbni sustav grada Petrinje i okolnih naselja. Kemijske analize vode rijeke Kupe prije i poslije prerade prikazane su u tablicama, iz kojih je vidljivo o kakvoj kvaliteti riječne vode se radi i o njezinoj sigurnosti za ljudsku uporabu.Clean, drinkable water is scarce on Earth, therefore the main task of every human should be to learn how to conserve water and pollute it as less as possible. The economic development and wealth of a country and it's inhabitants depends on available drinking water. The human population grows each year, but the ammount of available drinking water is getting smaller. Because of that, humans are forced to find new, better and more efficient methods for cleaning and analyzing water, so that it wouldn't harm the human health. The practical part of this paper refers to the chemical analysis of the water from the river Kupa, which after purification reaches the water supply system of the town of Petrinja and surrounding settlements. The results of the chemical analyses of the water drawn from Kupa before and after purification is shown in tables, from which the quality of the water can be determined and its safety for human use
ECONOMIC AND TECHNOLOGICAL MAINTENANCE OF APPLE PLANTATION ON A FAMILY FARM IVIĆ
No full textObiteljskim poljoprivrednim gospodarstvima u zadnje vrijeme pridaje se sve više važnosti. Iako se radi o većinom malim gospodarstvima, njihova uloga postaje sve značajnija u cjelokupnom gospodarstvu Republike Hrvatske. Održavanje nasada na obiteljskim poljoprivrednim gospodarstvima zahtijeva cjelogodišnju brigu o zasađenim jabukama s ciljem ostvarivanja pozitivnog poslovnog rezultata. U ovome će se radu prikazati tehnike i metode održavanja nasada jabuka na malom OPG-u Ivić koje se nalazi na području zapadne Slavonije. Od sadnje do branja i skladištenja uroda, kao i financijski rezultat, dat će se mogući prijedlog za poboljšanje i inovacije u dosadašnjem radu kao i mogući utjecaj za poboljšanje profita i smanjenje troškovaFamily farms have recently become increasingly important. Although these are mostly small businesses, their role is becoming more and more important in the entire economy of the Republic of Croatia. Plantation maintenance on family farms requires year-round care of planted apples in order to achieve positive business results. This thesis presents the techniques and methods of maintaining apple plantation on the small famili farm Ivić located in the area of Western Slavonia. From planting to harvesting and stocking as well as financial results, a possible suggestion will be given for improvement and innovation in the former business and possible impact on profit improvement and cost reduction

No full textCilj rada je analizirati poslovanje konkurentnih poduzeća “Optimum d.o.o.“ i “Zanatpromet d.o.o.“ za trgovinu, proizvodnju i usluge građevinskim materijalom. U radu su korištene horizontalna i vertikalna analiza, financijski pokazatelji pomoću kojih se može pobliže analizirati bilanca i račun dobiti i gubitka tih poduzeća te usporediti njihovo poslovanje. Iz rada se može zaključiti slijedeće: Z1: Horizontalna analiza poduzeća “Optimum d.o.o“ i “Zanatpromet d.o.o“. Pokazuje nam da je “Optimum“ bio uspješniji 2017./2016. god. od “Zanatpromet“ u bilančnim pozicijama, dok je već 2017./2018. god. “Zanatpromet“ bio uspješniji od “Optimum“. Z2: Vertikalna analiza poduzeća “Optimum d.o.o“ i “Zanatpromet d.o.o.“. Iz vertikalne analize može se zaključiti da je “Optimum“ imao u kratkotrajnoj imovini zalihe i potraživanja, dok “Zanatpromet“ većinom ima zalihe. Z3: Pokazatelji likvidnosti poduzeća “Optimum d.o.o“ i “Zanatpromet d.o.o.“. Pomoću pokazatelja likvidnosti može se uvidjeti kako “Optimum“ nije u svakoj godini likvidan te ne može podmiriti svoje obveze. “Zanatpromet“ je bio likvidan u gotovo svim godinama odnosno, podmirivao je svoje obveze. Z4: Pokazatelji zaduženosti poduzeća “Optimum d.o.o“ i “Zanatpromet d.o.o.“. “Optimum“ se financira iz tuđih izvora te ima poteškoća s vraćanjem sredstava, što znači da poslovanje nije toliko uspješno. “Zanatpromet“ financirao iz vlastitih izvora pa je zato poslovanje tog poduzeća uspješnije. Z5: Pokazatelji aktivnosti poduzeća “Optimum d.o.o“ i “Zanatpromet d.o.o.“. “Zanatpromet“ rabi svoju imovinu kako bi ostvario prihod i poslovao efikasnije, za razliku od “Optimum“ koji ipak ostvaruje manje prihode i efikasnost povećava u 2018. god. Z6: Pokazatelji profitabilnosti poduzeća “Optimum d.o.o“ i “Zanatpromet d.o.o.“. Iz pokazatelja profitabilnosti može se zaključiti da su oba poduzeća profitabilna, ali “Zanatpromet“ je uspješniji u svim pokazateljima.The aim of this paper is to analyze the business of competing companies Optimum Ltd. and Zanatpromet Ltd. for trade, production and services in construction materials. The paper uses horizontal and vertical analysis, financial indicators that can more closely analyze the balance sheet and profit and loss account of these companies and compare their operations. From the paper we can conclude the following: Z1: Horizontal analysis of “Optimum Ltd.” and “Zanatpromet Ltd.”. It shows us that “Optimum” was more successful in 2017/2016. from “Zanatpromet” in balance sheet positions, while in 2017/2018. “Zanatpromet” was more successful than “Optimum”. Z2: Vertical analysis of the companies “Optimum Ltd.” and “Zanatpromet Ltd.”. From the vertical analysis it can be concluded that “Optimum” had inventories and receivables in current assets, while “Zanatpromet” nevertheless acquired more inventories. Z3: Liquidity ratios of “Optimum Ltd.” and “Zanatpromet Ltd.”. With the help of liquidity indicators it can be seen that “Optimum” is not liquid in every year and cannot meet its obligations. “Zanatpromet“ has been liquid in all its years, ie, has fulfilled its obligations. Z4: Indicators of indebtedness of “Optimum Ltd.” and “Zanatpromet Ltd.” “Optimum” is financed from other sources and has difficulty returning funds, which means that the business is not as successful. While “Zanatpromet“ was financed from its own sources, the business of “Zanatpromet“ was more successful. Z5: Performance indicators for “Optimum Ltd.” and “Zanatpromet Ltd.” “Zanatpromet“ uses its assets to generate revenue and operate more efficiently, as opposed to “Optimum“ which nevertheless generates less revenue and increases efficiency in 2018. Z6: Profitability indicators of “Optimum Ltd.” and “Zanatpromet Ltd.”. From the profitability indicators it can be concluded that both companies are profitable, but “Zanatpromet” is more successful in all indicators
MICROBIOLOGICAL CONTROL OF FRESH CHICKEN MEAT
No full textZadatak ovog završnog rada bio je napraviti mikrobiološko ispitivanje svježeg pilećeg mesa. Unutar mikrobiologije, polje mikrobiologija namirnica najšire je područje istraživanja. Poznavanje mikrobiologije veoma je važno za osiguravanje odgovarajućih organoleptički ispravnih, zdravih i sigurnih namirnica. Mikroorganizmi su jako bitni u proizvodnji namirnica i u održavanju prehrambenog lanca u prirodi. Mikrobiologija mesa i proizvoda od mesa je posebna grana mikrobiologije, koja se bavi identificiranjem i utvrđivanjem porijekla mikroorganizama na tim namirnicama. Većina prisutnih mikroorganizama može imati određen utjecaj na kvalitetu mesa. Za ovo ispitivanje korišteno je svježe pileće meso: meso peradi u trupovima, porcionirano meso i meso u malim komadima, te iznutrice čija je analiza provedena međunarodnim ISO metodama. Dobiveni rezultati su pokazali da je svježe pileće meso mikrobiološki ispravno. Bakterije moraju biti u dozvoljenim količinama i ne smiju predstavljati opasnost za zdravlje potrošača. Ispitivanje na svježem pilećem meso provedeno je na slijedeće bakterije: Aerobno mezofilne bakterije, Enterobacteriaceae, Staphylococcus aureus, Sulfitoreducirajuće klostridije, Escherichiae coli, Salmonellae spp., Listeria monocytogenes.The task of this final work was to make a microbiological examination of fresh chicken meat. Within microbiology, the field of food microbiology is the broadest area of research. Knowledge of microbiology is very important for ensuring appropriate organoleptically correct, healthy and safe food. Microoganisms are very important in food production and in maintaining the food chain in nature. Microbiology of meat a and meat products is a special branch of microbiology, which deals with identification of the origin of microorganisms on these food. Most of the microorganisms present can have some impact on meat quality. For this test, fresh chicken meat was used: chicken meat in carcasses, portioned meat and meat in small pieces, and offal whose analysis was performed by international ISO methods, The obtained results showed that fresh chicken meat is microbiologically correct. Bacteria must be in the permitted quantities and must not pose a danger to the health of consumers. Bacteria must be in the permitted quantities and must not pose a danger to the health of consumers.

Using location-based Social Networks for optimal placement of tourist facilities: Zagreb case study
No full textIn the last decade, the advance of services and social networks that can store location coordinates and ratings by visitors has had a significant impact on how potential visitors choose their visit destination. The destination can be a landmark, a city, a restaurant, a hotel, etc., and people visiting the destination can be tourists or locals. Also, the data from these services can be used to analyse the location before potential investment in the tourist facility by an investor. Clustering unsupervised machine learning algorithms can be used for that analysis, combining individual municipalities of a city into clusters that have similar properties, making potential investors informed about municipality's properties. In this paper, the main goal is to propose an optimal placement model based on the available information. A prerequisite for this is the analysis of location-based service that can be used to make decisions about the location of a restaurant or bar, and the amount of information available at these service for the city of Zagreb. The proposed model is based on a k-means algorithm that belongs to unsupervised machine learning algorithms. The result of the analysis is the list of municipalities in the city of Zagreb divided into clusters with similar properties. The municipalities are divided into six clusters and that division brings objective knowledge to the potential investor. These results can be used as a basis for decision- making or as a test of expert recommendation. The proposed model can be used for other purposes, depending on the area of interest and the amount of data available on the service
