Abstract

Organic farming collects all the imagination of farmers and consumers seriously and is responsible for avoiding chemicals and fertilizers that are toxic to the environment, in order to obtain healthy environmental conditions. In this study raised the concept of organic farming so that farmers who still use conventional ways easier and interested to switch to organic methods. The purpose of this research is to create a set of tools that facilitate the farmers in controlling the production process, so that production becomes more stable and value-added.The method used in this research is qualitative method of observation, in depth interview, and focus group discussion. Based on the observations, it is known that the farmers are traditional farmers, so they are still based on the constellation and the climate where it is not applicable due to climate change, then the absence of good means of information and reminder to assist the population in controlling the stages of planting, fertilization and so on.This research produces a series of tools, applied to the learning process of traditional farmers with a cubism design developed in 1910-1914.The design focuses on the simplification of geometric forms of nature, in which the flow arises from the appearance of boredom of classical streams full of ornaments.

Abstract

The study investigates the influence of operating parameters such as initial pH and distance between electrode on COD and color removal from a laboratory scale batch electrocoagulation reactor using aluminum plate (Al) with a broad cross section of 80x80 mm2 and 2 mm thick as the electrode. Synthetic wastewater Direc Red 12 B® and Direc Black Ex® is used in the study with a volume of 800 mL. The variations of experiments are distance between electrodes (2 cm, 3 cm and 4 cm) and the initial pH (4, 5, 6,7). The samples are taken every 5 minutes for 60 minutes operating time. The results of the study indicate that electrocoagulation optimal condition occurs at electrode distance 2 cm and initial pH 5 with the color removal efficiency 94.5% of the Direc Red 12 B® and 98.3% of Black Direc Ex®, COD removal 91.25% of Direc Red 12 B® and 84.92% of Direc Black Ex®.

Abstract

Higher education institutions can play a role in reducing greenhouse gas emissions through solid waste management. One of the solid waste sources in the campus is a canteen. Surabaya University (Ubaya) is one of the higher education institutions in Surabaya has two canteens that generate waste everyday. In the canteen waste is separated into food waste, food cardboards and plastic bottles. Food waste and food cardboards has not processed yet. A research related to the potential utilization of canteen waste need to be  conducted. The aims of the research are  determining the amount of organic waste generation in Ubaya canteen and calculating the greenhouse gas that can be derived if organic waste is processed into biogas. The scope of calculation was CH4 generation. The research is conducted in the Keluwih Canteen.  The estimation of canteen waste is taken for ten days. The surveys conducted during November 2017. The calculation of green house emission from solid waste was referred to Intergovernmental Panel on Climate Change (IPCC)  2006 guidelines.  The results of the research indicated that the average quantity of food waste is 6,3 kgs per day, 5  kgs per day of food cardboards and  Surabaya University can contribute to reduce green house gas emission (CH4) about 0,85 kg CH4 per day.

Abstract

The increasing of student number over the past four years urged Surabaya University to develop campus facility that could serve as a learning media for the academic community in the campus and the community around campus. The proposed facility was composting area. Composting area construction was necessary because the accretion of students would be followed by the growing of solid waste generation. The estimation of solid waste that  be carried to composting area had not been done before. This research was conducted with the aim of: 1. Estimating the quantity of solid waste generation that disposed to composting area 2. Calculating the greenhouse gas reduction that can be achieved by solid waste composting. Solid waste estimation was done before separation process in the composting area. Research was done by  survey and observation. Survey area was engineering  faculty. Sampling  for solid waste estimation was undertaken at TG building. The results  indicated that 70 % of the solid waste was anorganic waste and solid waste generation was 25-50 kgs daily. Solid waste composting process was set once in a week which composting period was seven days. The calculation of green house emission was referred to IPCC guidelines. The result of calculation was Surabaya University could contribute to reduce green house gas emission (CH4) about 40,5 kg CH4.

Abstract

Fish fry feed mainly on Tubifex worms to ensure its proper growth. From 2 – 15 days after hatching, the fry would be feed Tubifex worms. Thus far, the worms’s supply came from another village so the dependency of Tubifex worms is very high. Tubifex worms had cultured before but the farming was unsuccessful. The harvesting worms hadn’t been able to meet the needs of the fish breeders. One of the causes was the knowledge and skill of Tubifex worms breeders was very low so the failure of Tubifex worms farming was quite high. The community development program was created to overcome the problem. The aims of the program were to ugrade the knowledge and the skill of Tubifex breeders and to improve the quantity and quality of Tubifex worms. There are 3 activities carried out so that the expected goals could be achieved: 1. Workshop of Tubifex worms farming methode 2. Assistance of Tubifex worms farming 3. Providing books or literatures of Tubifex worms farming. The methode of Tubifex farming that was trained to the breeders was a rack culture system. The training material included how to build rack system, water circulation piping and water droplets, preparing worm media and feed, the process of worm quarantine, how to breed Tubifex worm, and the harvesting process. According to the breeders, the system was cheaper and simpler than tray systems that use plastic container, which had been applied before. A rack culture system container was made by utilizing used goods, for example plastic banner and used pond tarps so that the cost could be lower. Farming rack could be made from bamboo or cheap timber that available around neighborhood. The yield of rack system application was able to supply the Pungpungan’s fish breeders more than 30%. The conclusions of this program were 1. Tubifex worms farming using a rack culture system could improve the quantity and quality of Tubifex worms 2. The worms breeder prefered a rack culture system because it was cheaper and easier to apply.

Abstract

The first step that possible for Surabaya University (Ubaya) to realize a sustainability campus was waste production reduction. A research related to solid waste management in Ubaya need to be conducted. The aims of the research were 1. To determinate the economical organic solid waste composition in faculty of engineering 2. Estimating the quantity of economical organic solid waste in faculty of engineering 3. Calculating the greenhouse gas that can be reduced by managing the economical organic solid waste. The scope of calculation was CH4 generation. Research is done by survey of solid waste generation. Survey was conducted at faculty of engineering Ubaya, in TA building until TS building plus faculty of engineering gazebo. The estimation of economical organic solid waste was taken for eight days in September 2016. The calculation of green house emission from solid waste was referred to Intergovernmental Panel on Climate Change (IPCC) 2006 guidelines. The results of the research indicated that the composition of economical organic solid in the faculty of engineering was white paper, brown paper, cardboard, and juice and tea packaging. The average quantity of economical organic waste generated in the faculty of engineering per day were white paper: 5.44 kg, 1.055 kg of brown paper, cardboard 2.51 kg and 0,765 kg of tea and juice packaging. Greenhouse gas (CH4), which could be lowered if the economical organic waste is managed was around 1.14 kg / day.
