Abstract

Variation of land use can affect the quality of groundwater and increase the potential for groundwater contamination. Physical environmental conditions that have a low sensitivity to contamination of groundwater, but the use of land which could potentially generate pollutants, such as industrial areas, residential, the agricultural activity can increase the risk level of contamination in the groundwater in the area. The purpose of this study is to develop a groundwater risk to contamination map in the shallow aquifer and to determine priority areas of groundwater quality monitoring in Salatiga Groundwater Basin. Groundwater risk to contamination map was prepared on aspects of land use and the degree of vulnerability of groundwater to contamination using DRASTIC methods and spatially was prepared by using Geographic Information System. Results of the assessment of risk levels obtained worth the risk index 93-204. The risk index values are grouped into five (5) classes of risk: low, low to medium, medium, medium-high, and high. The output of this research can be input for local governments in understanding the possible spread of groundwater contamination as well as choosing the right strategy for the conservation of groundwater resources in the Groundwater Basin of Salatiga.

Abstract

Herbicides increase labor but pollute water sources, destroy soil, and leave toxic residues on agricultural products. Eradication of weeds that are environmentally friendly can be done using bioherbicides, including the allelopathy of Siamese leaves (C. odorata). The research was conducted at the Laboratory of the Indonesian Bean and Tuber Crops Research Institute (BALITKABI) Malang, in April 2017 using a factorial completely randomized design that was repeated three times. The first factor: the concentration of C. odorata extract consisted of: a concentration of 0% (w / v), a concentration of 10% (w / v), a concentration of 20% (w / v), a concentration of 30% (w / v). The second factor: types of commodities, consisting of: soybeans, green beans and rice. The manufacture of simplicia was started with the baking of fresh C. odorata leaves at 65 ?C for 24 hours and then blended. Weighed 60, 40, 20 grams of the simplicia and immersed in 95% ethanol for four hours. Then at each level 200 ml of distilled water was added and filtered with filter paper. The seed testing is done with CD paper which is first moistened with the solution, the seeds are arranged on the CD paper and set up. During germination the moisture of the paper is maintained by giving 10 ml of the extract solution according to each treatment level. The variables observed were radical length (root), plumule length, and number of leaves at 4, 7 and 10 hours. The results showed that C. odorata leaf extract with a concentration of 20% (w / v) and 30% (w / v) was due to bioherbicides which can control weed growth.

Abstract

Conventional crop cultivation systems experience several limitations, including the season, the length of day that does not match the needs of the plant, the availability of water and the narrowing of agricultural land due to population growth. Indoor farming can be a solution to overcome limitations in conventional cultivation. Indoor farming is an indoor farming system with a controllable climate, including light, temperature, evaporation and air circulation. Sunlight is the main light source in nature. Light is an electromagnetic wave that carries a form of energy. Sunlight has many functions for life on earth, one of which is as a source of energy for plants to carry out photosynthesis. Photosynthesis is a biochemical process for the formation of food substances such as carbohydrates carried out by plants. Photosynthesis takes place using chlorophyll, carbon dioxide and water and the help of sunlight energy. Sunlight consists of UV rays, visible rays and infrared rays. Visible light has a wavelength between 400 - 700 nm. Visible light is the light that plants use for photosynthesis. Chlorophyll can absorb red (600-700 nm) to blue (400-500 nm) wavelengths. The quality of sunlight is good for plant growth because it has the entire spectrum needed for photosynthesis. Artificial light from lamps that are used as a substitute for sunlight in order to support plant growth must have the quality according to plant needs. The quality of light from each source is not the same. This is the basis for conducting the study, namely comparing the quality of sunlight and artificial light sources such as lamps. Based on the studies that have been done, the color spectrum of artificial light that approaches the spectrum of sunlight is the white color spectrum. A more efficient substitute for the white color spectrum for plant photosynthesis with the pigment chlorophyll is the blue and red or growlight color combination.

Abstract

Climate change affects the existence of agricultural production from time to time, especially by increasing the concentration of CO2 in the atmosphere which has an impact on increasing temperatures. Temperature as an environmental factor influences plant physiological processes, which in turn affects plant production. In addition, climate change causes high fluctuations between the intensity of rain and drought, giving rise to La-Nina and El-Nino phenomena. This condition is a threat to food security and thus stakeholders are obliged to take concrete actions in the form of mitigating the impacts of climate change. Agroforestry is the first choice of agricultural cultivation technology by promoting trees as ecosystem service providers in the form of microclimate and soil (nutrients and water) which are beneficial for cultivated crops (seasonal). This cultivation technology also increases the potential of suboptimal land in Indonesia, which is quite extensive. Agroforestry systems improve suboptimal land quality and support climate change adaptation and mitigation efforts. Some food crops such as upland rice, soybeans and maize can be cultivated in agroforestry systems. Although the production of food crops in agroforestry systems is relatively lower than in open areas, agroforestry is considered to have the ability to support food security in terms of soil and water conservation, diversification of land use and the adequacy of micronutrients.

Abstract

Climate change that we are experiencing today is triggered by global warming which causes air temperature to rise, drought-land degradation, fluctuating rainfall, floods, landslides, pollution, and rising sea levels. In the agricultural sector, this results in decreased soil fertility, decreased agricultural yields, physiological effects on plants, weed disturbances and attacks by pests. Therefore, the estimation strategy and the provision of adaptive technology include applying plant-invitro culture technology that can adapt to climate change. The problem of this paper is the decrease in productivity and the stagnation of secondary metabolite biomass production in plants. This problem can be overcome by adapting in vitro culture techniques to produce secondary metabolites and plant development. In vitro culture has advantages including it does not depend on climate, altitude, weather and environmental temperature. The aim of this study was to adapt the in vitro plant culture techniques to obtain secondary metabolites and adaptive plant development. The method used is a review of the literature related to in vitro culture techniques that can produce secondary metabolite biomass and the development of various plant varieties. The conclusion of this research is that in vitro culture techniques can produce a variety of secondary metabolites and adaptive plants. The implication of this paper is to obtain a variety of secondary metabolite biomass and various plants that are resistant to climate change.

Abstract

Climate change due to current global warming is something that cannot be prevented and is very influential in the agricultural sector, especially in producing horticultural seeds. In producing seeds, there are additional special stages compared to plant cultivation in general. The existence of pollination in hybrid plants, the selection of physiological ripe fruit for seed production, seed extraction to seed drying are very dependent on the climate. Therefore, it is necessary to have a seed production strategy, namely the knowledge to find out the rainfall for this year and the following year in order to adjust the planting time, determine the planting location according to the variety recommendations, modify cultivation techniques to harvest and save the seeds that will be optimal and produce quality seeds. Furthermore, there are also plant breeding strategies in producing new superior varieties that are productive and resistant to climate change.

Abstract

The fabrication industry plays a large role as a source of agricultural land pollution, especially in areas close to factories. Corn and rice plants are food crops that are needed by the community. Along with increasing environmental pollution, research is needed. The purpose of this study was to determine the effect of plant media contaminated with plant waste on the vegetative growth of corn and rice plants. The research was carried out in the greenhouse and laboratory of the Land Resources of the Faculty of Agriculture of the East Java National Veterans Development University. This research uses a completely randomized factorial design with 2 factors. The first factor is the type of plant which consists of 2 factors (corn plants and rice plants). The second factor is the type of media contaminated with factory waste consisting of 6 levels of treatment (paper mills, pharmaceutical factories, trias factories, leather factories, batik factories and garden lands). The results of the treatment were 12 treatment combinations with 3 replications and using the Least Significant Difference test (LSD) of 5%. The results showed that plant media contaminated with factory waste showed a real interaction with the length of the corn plant + paper factory, corn + pharmaceutical factory, corn + trias factory and corn + batric factory at the age of 4 HST. The types of corn plants respond better at the beginning of plant growth, plant length, number of leaves and root length. Rice types give a better response to the number of leaves, tillers, number of tillers and number of roots. The type of pharmaceutical planting media gives a better effect on the parameters of plant length and number of leaves.
