REVIEW : PEMANFAATAN TEKNOLOGI GREENHOUSE DAN HIDROPONIK SEBAGAI SOLUSI MENGHADAPI PERUBAHAN IKLIM DALAM BUDIDAYA TANAMAN HORTIKULTURA

Horticulture plant is essential component of agricultural development. It brings benefits products horticulture meet their food needs , aesthetic and to maintain health and environment. Climate change and the limited resources land causing loss for farmers food crops and horticulture. The purpose of drafting this paper is to inform the utilization of technology greenhouse and hydroponics as solutions to deal with climate change in the cultivation of plants horticulture. To get the result harvest season which is satisfying in the cultivation of plants horticulture , need to pay attention to environmental factor growing plants. The utilization of greenhouse in the cultivation of plants is one of a manner to give the environment that were more accessible for the condition of optimum position for the growth of plants. The use of hydroponics in cultivation crop can be implemented in greenhouse to keep the growth of plants optimally and protected from outside influences

Analysis of Chilli Plant Physiology Conventional System, Green House Hydroponic Utilization System Using Fuzzy Logic

The chili (Capsicum Annum L) is one of the vegetable crops that have high economic value. Red hydroponic cultivation is an effort to increase the yield of red chillies by minimizing the use of chemical fertilizers, thus using biological fertilizer on red pepper plant is expected to increase the growth and yield of red peppers. This study aims to determine the physiology of red chili plants with hydroponic system with the utilization of green house. Both physiology studies of red pepper plant with hydroponic system with green house utilization and the three physiological studies of red pepper plant with hydroponic system with green house utilization. The variables observed in this study include plant height (cm), plant width (cm), and number of leaves (strands). The method used conventional chilli plant, hydroponic system is Fuzzy Logic The main discussion is to study the comparison of cultivation of chilli plants with hydroponics and conventional using plant physiology with green house. The results of physiology simulation of red pepper cultivation using plant length, weight of plant weight, hardness of plants, number of leaves, number of flowers, water content produce better hydroponic system growth than conventional system on red pepper plant. In the cultivation of soil media plants require fertilizer is always done watering in times of growth while the hydroponic media require nutrient fertilizer hydroponic kits have been found. This is according to previous research that the parameters of the success rate of a hulticulture cultivation is can be seen from the vegetative and generative plants. The Conclusion of the study of chili cultivation with hydroponics more than conventional physiological review of plant methods of fuzzy logic.

Experimental Study of Municipal Solid Waste (MSW) Landfills and Nonauthorized Waste Damps Impact on the Environment

A purpose was an analysis of waste disposal sites existing in the Leningrad region and a choice of facilities potentially suitable for the removal and utilization of greenhouse- and other gases. In order to achieve the purpose in view, data were collected on the arrangement of non-authorized landfills and waste dumps within the Leningrad region. The preliminary visual evaluation and instrumental monitoring were carried out for 10 facilities. The evaluation of greenhouse- and other gas emissions into the atmosphere as well as of ground water pollution near places of waste disposal was performed. A databank was created for waste disposal sites where it could be possible to organize the work on removing and utilizing of greenhouse gas.
 The conducted examination stated that landfills exert negative influence on the environment in the form of emissions into the atmosphere and impurities penetrating underground and surface water. A volume of greenhouse gas emissions calculated in units of СО2 – equivalent from different projects fluctuates from 63.8 to 8091.4 t in units of СО2 – equivalent. Maximum summarized emissions of greenhouse gases in units of СО2 – equivalent were stated for MSW landfills of the towns of Kirishi, Novaya Ladoga and Slantsy, as well as for MSW landfills near Lepsari residential settlement and the town of Vyborg.

Utilization of Greenhouse (Lean-to Structural Frame) as a Solar Dryer for Drying Lemon Fruits Part I: Drying Process under High Air Temperature.

A solar lean-to greenhouse dryer was designed, constructed and tested for drying lemon fruits at the experiments and researches field, Faculty of Agriculture, MansouraUniversity (latitude and longitude angles, respectively, are 31.04ᵒN and 31.35ᵒE, and 6.72 m mean altitude above the sea level). In this study a new concept has been taken into consideration to maximize the greenhouse effect (thermal trapping) by using architectural form of lean-to greenhouse structural frame. The experimental work was carried out from 21st to 26th of August 2016. The obtained results showed that, using the northern wall reflector caused in increasing both the intensity of solar radiation inside the dryer and the indoor air temperature by 36.30% and 60.90%, respectively. The daily average solar radiation incident outside and inside the solar dryer were 5.188 and 3.383 kWh, respectively with effective transmittance of 65.21%. Using the northern reflector wall increased the daily average indoor solar radiation by 36.12%. The daily average outdoor and indoor air temperatures were 30.1 and 48.4oC, respectively. Accordingly, the solar dryer increased the indoor air temperature over the outdoor by 60.80%. These conditions of solar dryer caused in decreasing the daily average air relative humidity from 67.31 to 28.38% with reduction percentage of 38.93%. Three different shapes of lemon fruits (slices, half and whole lemon) was dried from initial moisture content of 87.04% (w.b.) to the final moisture of 17.30, 17.38 and 17.69% (w.b) within 3, 5, and 6 days, respectively.

Greenhouse Heating With a Fresh Water Floating Collectors Solar Pond: A Feasibility Study

The fresh water floating collectors solar pond was investigated both experimentally and theoretically in a previous work, and it is now matched, by simulation, with the heat load requirements of a greenhouse. Results of the simulation indicate that such a pond is a potential energy source for greenhouse heating. This is especially true when the material properties are such that solar absorption and storage are enhanced. To demonstrate this point, three sets of collectors constructed with materials of different physical (radiation) properties were tested. One set is constructed of common materials which are readily available and are normally used as covers for greenhouses. The second set is made of improved materials which are also available but have a smaller long-wave transmittance. The last set is made of “ideal” material which additionally possesses selective radiation absorption properties. Collectors made of “ideal” materials make a superior solar pond; thus, manufacturing films with improved properties should become a worthwhile challenge for the agricultural polyethylene-films industry. Preliminary economic studies indicate that even with the low oil (< $20/Bbl) prices which exist between 1986-1989, the fresh water floating collectors solar pond provides an economically attractive alternative to the conventional oil-burning heating system. This is especially true in mild climate areas and when the large initial investment is justified by long-term greenhouse utilization planning.
