Food production is of symbolic and practical importance in sustainable cities. Vegetable gardening in public spaces and community gardens is one of the most important topics to investigate as a possibility of food production in modern cities. The aim of this research is to explore how the application of ˈRhyzo BZˈ fertilizer microparticles could increase the stability and viability of biological and chemical agents for a longer time period with the time-release mechanism during pepper (Capsicum annuum var. macrocarpum L.) cultivation in urban gardens. The cultivation environment was monitored by an agrometeorological station continuously logging the following parameters: air temperature, humidity and pressure, soil temperature and humidity, precipitation, wind speed and direction, and leaf wetness. The optimization process of ˈRhyzo BZˈ fertilizer encapsulation in the biopolymers microcapsules was performed under optimal conditions of concentrations of sodium alginate (2 %) and calcium nitrate(1.5%), for optimal microcapsules enriched production. The experimental urban garden was set up in Zagreb (Faculty of Electrical Engineering and Computing). Planting of pepper seedlings (cultivar ˈSlonovo uhoˈ) was done on May 26, 2021. Harvest of pepper fruits lasted from July 13 to October 12, 2021. After harvest, in samples of pepper fruits some chemical properties were determined (polyphenols and carotenoids. The obtained results showed that the application of ˈRhyzo BZˈ fertilizer microparticles increased the morphological and chemical properties of the fruits cultivated in urban gardens.

Budući da je koncept pametnih domova sve aktualnije područje razvoja i istraživanja, a ujedno sve prisutniji i prihvaćeniji koncept od strane društva općenito, ovaj rad se bavi upravo tim područjem. Temeljna ideja rada razvoj je aplikacije za pametni sat, koja će korisnicima omogućiti još jednostavnije i pristupačnije upravljanje sustavom pametnog doma. Aplikacija je razvijena za operacijski sustav Tizen, kao centralni sustav pametnog doma korištena je platforma OpenHAB, a OpenHAB REST API je sučelje koje se koristi kako bi se omogućila potrebna komunikacija između aplikacije i sustava pametnog doma. In this thesis, concept of the smart homes is presented since the interest in this area is rising exponentially every day as the society is developing interest in newer technologies to make life easier and more efficient. The core idea of this thesis was to develop an application for the smart watch, which will make the user experience of controlling the smart home system easier and more accessible. The application was developed for the Tizen operation system, whereas OpenHAB was used as a central system for the smart home. OpenHAB is an interface which was used to enable the necessary communication between application and smart home system.
