No full textU radu je je prikazan utjecaj debljine lima (S235) na parametre rezanja. Pokus se provodio na pločicama 80 mm x 80 mm. Prilikom rezanja na plazmi mijenjaju se brzine rezanja i tlak plina kojim režemo kako bi mogli vidjeti utjecaj debljine lima na kvalitetu reza. Kvaliteta reza definirana je kao hrapavost obrađene površine i količina okujine s donje strane reza. Tehnika rezanja plazmom već se upotrebljava dulje vrijeme , a i dalje teži unaprijediti kvalitetu reza uporabom različite tehnike rezanja plazmom.This work present effect of sheet thickness (S235) on cutting parameters. The experiment was performed on 80x80 mm tiles, while we cut on plasma we change the speed of cutting and gas pressure how we cut to impact of thickness on quality of cut. Quality of cut is defined as roughness of surface and amount of damage from the bottom of the cut. The plasma cutting techniques is already being used for a long time, and it is still trying to improve the cutting quality by using different plasma cutting techniques
Methods of managing agricultural mechanization
No full textU završnom radu objašnjena je opća podjela tla koja je bitna kako bi dalje znali odabrati način obrade tla. Tehnike obrade tla mogu biti konvencionalne koje se u Hrvatskoj najviše koriste i nekonvencionalne tehnike koje još nisu toliko poznate, a ljudi se boje isprobavati nešto novo. Zato sam pokušala objasniti prednosti nekonvencionalne obrade tla. Mehanizacija ima ključnu ulogu u poljoprivredi, pogotovo kada gledamo troškove. Troškovi mehanizacije mogu biti fiksni ili radni troškovi. Svaka mehanizacija se tokom radnog vijeka troši, zato je bitno znati izračunati amortizaciju. Svaki način izračuna amortizacije za stroj objasnila sam primjerom. Kako bi od stroja dobili najbolji učinak moramo znati kako ga izračunati i o čemu on ovisi. Na kraju najbitnije je kako što više taj učinak povećati da stroj napravi što je više moguće posla uz što manje gubitke i troškove.The final work explains the general division of soil that is important in order to further know how to choose the soil treatment method. Soil techniques can be conventional, which are commonly used in Croatia and unconventional techniques that are not so well known, and people are afraid to try something new. That is why I tried to explain advantages of unconventional soil treatment. Mechanization plays a key role in agriculture, especially when we look at costs. The cost of mechanization can be fixed or labor cost. Every mechanism wears during the working life, so it is important to know how to calculate the amortization. Every way I calculated the amortization for the machine I explained by example. To get the best performance from the machine, we need to know how to calculate it and what does it depend on . In the end, it is important to know how to increase this performance so that the machine works as much as possible with less losses and costs

Youth enterprises as rural developers
No full textU ovome radu obrađena je tema poduzetništva i poduzetnika te njihova uloga u poljoprivredi. Nakon teorijskog dijela u radu baziranog na poduzetništvu slijedi opis područja na temelju kojega će se analizirati poljoprivreda i predložiti ideja mladog poduzetnika. Iako je selo vizualno u fazi zalaza, ta tvrdnja je kriva jer je selo vitalan faktor razvoja društva u cjelini te je zbog toga potrebno tragati za pokretačima obnove i napretka sela.
Obavljanje poljoprivredne djelatnosti zanimljivo je posjednicima poljoprivrednih površina i državi. Poljoprivrednicima je zanimljivo zbog ostvarivanja državnih poticaja a državi zbog osiguravanja prehrane za stanovništvo i jer neizravno utječe na smanjenje nezaposlenosti. Odluka da se postane poduzetnikom većinom je rezultat osjećaja zasićenja radom zbog poslodavaca koji na adekvatan način ne cijene rad i ne nagrađuju te poduzetnik želi postati „ sam svoj gazda“.This paper deals with the topic of entrepreneurship and entrepreneurship and their role in agriculture. After the theoretical part in entrepreneurship-based work, a description of the area will be used to analyze agriculture and suggest the idea of a young entrepreneur. Although the village is visually at a standstill, this claim is the fault because the village is a vital factor for the development of the society as a whole, and it is therefore necessary to seek for the drivers of the reconstruction and the prosperity of the village.
Carrying out agricultural activities is interesting for the owners of agricultural land and the state. It is interesting for farmers to get state incentives and to the state for securing food for the population and because it indirectly affects the reduction of unemployment. The decision to become an entrepreneur is mostly a result of the satiation of work by employers who do not cost a job in an adequate way and do not reward, and the entrepreneur wants to become "his own boss"
Cost management on the example of company Đuro Daković Aparati d.d.
No full textRazumijevanje računovodstvenog praćenja troškova jako ovisi o poznavanju strukture troškova poduzeća te o poznavanju zakonitosti teorije troškova. Tokom čitavog procesa odvijanja poslovne aktivnosti u poduzeću, troškovi su prisutni, a o njima uvelike ovisi budućnost poduzeća. Budući da evidencija troškova podrazumijeva upravljanje velikim brojem podataka, potrebno je da računovodstvo poduzeća redovito prati troškove koji nastaju u poduzeću. S obzirom da su troškovi pokazatelji financijskih i nefinancijskih transakcija u poduzeću, računovodstveno praćenje troškova podrazumijeva praćenje obavljenih transakcija u tom kontekstu.
Cilj ovog rada je na konkretnom praktičnom primjeru poduzeća Đuro Đaković Aparati d.d. prikazati računovodstveno praćenje troškova i njihovu strukturu.Understanding accounting cost tracking depends heavily on knowledge of the company's cost structure and knowledge of the legality of cost theory. Throughout the entire process of running business activities in the company, costs are present, and the future of the company is largely dependent on them. Since cost accounting implies a large number of data management, it is necessary that enterprise accounting regularly monitors the costs incurred by the enterprise. Given that the costs are indicators of financial and non-financial transactions in the enterprise, accounting cost accounting implies monitoring the transactions performed in that context.
The goal of this academic work was to represent accounting of expenses and their structure on practical example on real business expenses of Đuro Đakovic Aparati d.d
The most important damage and the way of such damage in the manufacture of tomato
No full textRajčica je jedno od najraširenijih povrća u svijetu. Jede se plod odnosno boba. Cvjetovi rajčice su skupljeni u cvatu u obliku grozda. Pripada skupini termofilnih kultura. Minimalna temperatura klijanja sjemena i nicanja jest 11 ˚C do 13 ˚C, a maksimalna oko 35 ˚C. Optimalna temperatura rasta jest 20 ˚C do 25 ˚C danju i 13 ˚C do 17 ˚C noću. Rajčica se koristi diljem svijeta s toga je važno znati neke najbitnije štetnike i bolesti koju ju napadaju. U ovome su radu opisani neki od njih a to su: tripsi, štitasti moljci, gusjenice -lisne sovice, sovice pozemljuše i ostale sovice, te muhe.Tomato is one of the most widened vegetable crops in the world. Tomato fruits are used as food. Tomato inflorescence has a form of a truss. Tomato belongs to the group of warm season crops. The minimum temperature for seed germination and plant emergence is between 11 ˚C and 13 ˚C, and the maximum temperature is around 35 ˚C. The optimal temperature of tomato growth is between 20 ˚C and 25 ˚C by day, and between 13 ˚C and 17 ˚C at night. Tomato is used throughout the world and it is important to know some of the most important pests and diseases that it attacks. Some of these are described in this paper, such as triads, shrubbery moths, caterpillars, lynx straps, snaps and other sutures and flies
Irrigation in ecological agriculture
No full textVoda je najrasprostranjenija tekućina na Zemlji i zauzima tri četvrtine njene površine. Gradivna je tvar svih živih bića, sudjeluje u odvijanju procesa kao što je fotosinteza, koristi se za navodnjavanje poljoprivrednih površina, proizvodnju i pripremu hrane, te u konačnici za piće. Zbog opskrbe biljaka mineralnim tvarima ključan je faktor u ekološkoj poljoprivrednoj proizvodnji koja se zasniva na navodnjavanju i odvodnji vode.
Suvremena tehnologija omogućila je različite vrste sustava za navodnjavanje koji ne zahtjevaju ljudsku radnu snagu i utrošak vremena, uz utrošak najvećeg prirodnog resursa – vode. Također, omogućila je i proizvođačima konvencionalne poljoprivrede vrlo laku manipulaciju sustavima za navodnjavanje koji u tim slučajevima uz raspodjelu vode raspodjeljuju kemijska sredstva, pesticide i gnojiva, čime dolazi do onečišćenja tla, zagađenja podzemnih voda i onečiščenja okoliša. S toga, zbog razvoja čovječanstva, koji je utjecao na onečišćenje okoliša i smanjenu kvalitetu života u sadašnjosti, a i u budućnosti, cilj ekološke poljoprivrede je očuvanje prirodnog ekosustava i krajolika.Water is the most widespread fluid on Earth and occupies three – quarters of its surface. It is basic substance of all living beings, it is participating in processes such as photosynthesis, it is used for irrigation of agricultural land, food production and preparation, and ultimately for drinking. Due to the supply of plants with mineral substances, it is a key factor in organic farming based on irrigation and drainage.
Modern technology has allowed different types of irrigation systems that do not require human labor and time consuming, with the greatest natural resource - water consumption. It has also allowed conventional farming producers a very easy manipulation of irrigation systems, which in these cases distribute chemical agents, pesticides and fertilizers in water dispersion, leading to soil contamination, groundwater pollution and environmental pollution. Therefore, due to the development of humanity, which has had an impact on environmental pollution and reduced quality of life in the present, and in the future, the goal of ecological agriculture is to preserve the natural ecosystem and landscape

Knowledge and human resources management in enterprise
No full textZnanje se u današnje vrijeme smatra osnovnim resursom suvremenih organizacija, temeljnim izvorom moći i korporacijskom imovinom kao nevidljivom imovinom bez koje se teško postiže uspjeh. Znanje i njegova uporaba postaju odlučujući parametri novog tipa rasta i razvoja koji podrazumijevaju mijenjanje strukture proizvoda koji sve više sadrži intelektualnu komponentu. Društvo budućnosti će najsigurnije biti determinirano sposobnošću učenja te sposobnošću proizvodnje i potrošnje znanja pojedinaca, organizacija i društva u cjelini.Knowledge today is considered to be the basic resource of contemporary organizations, a fundamental source of power and corporate property as invisible property without which is difficult to achieve success. Knowledge and its use are becoming the decisive parameters of a new type of growth and development that imply changing the structure of a product that increasingly contains an intellectual component. Society of the future will certainly be determined by the ability to learn and the ability to produce and consume knowledge of individuals, organizations and society as a whole
