Wastewater Use

ABSTRACT: The use of wastewater in agriculture has been practiced on an increasing scale over the past decades because of its fertilizing potential and the reduction in demand for surface water and groundwater. However, this practice may bring harm when performed without planning, not respecting the capacity of the soil to recycle organic waste. The most common problems are contamination of surface and groundwater via leaching and runoff, as well as accumulation of nutrients and potentially polluting elements that compromise chemical, physical and biological characteristics of the soil. The biological compartment, represented by the micro, meso and macrofauna, plays an important role in nutrient cycling, decomposition of organic matter, particle movement and transport of materials at different depths, helping to maintain soil physical and chemical characteristics. In this sense, this paper aims to discuss the effect of using different kinds of wastewater in agriculture on soil biology, highlighting strengths and weaknesses, as well as emphasizing the need to conduct investigations that enhance the positive aspects of wastewater use associated with edaphic processes.

O.; ELECTRICAL CONDUCTIVITY OF SATURATED EXTRACTSDETERMINED BY THE REDUCED MAJOR AXIS METHOD USING MIXTURES OF SOIL AND WATER IN A 1:2 RATIO  2  ABSTRACT This experiment was carried out aiming to estimate electrical conductivity of saturated water soil extracts (CEes) using mixtures of soil and water in a 1:2 ratio (CE1:2). Soil salinity was monitored in a field where melon was irrigated with water which salinity level was increasing during the cycle (S1 = 0.6; S2 = 1.9; S3 = 3.2 and S4 = 4.5 dS m-¹). Samples were taken from two consecutive melon cycles at three depths (0-15, 15-30 and 30-45 cm). At 70 days after seeding (DAS) of the first cycle and at 30 and 70 DAS of the second CEes and CE1:2 were determined from compounded samples taken from 15 treatments with three depths each. Data were adjusted for all data and depth using linear regression and the reduced major axis method (RMA). The equation CEes = 8.094 CE1:2 + 0.0149 (R² = 0.9112) obtained using all data through RMA, showed a degree of predictability similar to the linear regression obtained for different depths and dates. Soil electrical conductivity was inversely correlated to the soil:water ratio. KEYWORDS: Cucumis melo, salinity

The habit of Karang Joang people is throwing garbage, inherited from generation to generation. Most of treating’s their garbage are by burning it in the yard, throwing into the garden or the river. The transportation to take garbage that isn’t intensive by city officers and the lack of knowledge in managing the garbage greatly affects the pollution condition of the air, soil and water in the village. This research focuses on the patterns of society in treating organic waste and inorganic. Environmental conditions in the village to make some attention from the city government Balikpapan. Because the village is located in a protected forest manggar should be kept clean. We distributed questionnaires to 500 housewives that are living in 12 areas near the river. We interviewed one of the small shop and 5 housewives about what they buy and how dispose of waste in one day. Approximately 5-7 sachet plastics and around 200-300 grams of organic garbage. And approximately one drum of water is used for one family. Six months after distributing questionnaires and analyzing, we held a workshop with theme on the importance of eco-friendly living, composting of organic garbage, and counseling about bank of garbage program for 32 leaders in the village. Then we try to find solutions about how to build the consciousness and management in solid waste. In this study, some possible solutions have been presented by transfer environmental technologies

Initial Process

Caulerpa lentillifera is a type of green seaweed that is cultivated in tropical and subtropical areas. The objectives of this study were to determine the characteristics of the sulfated polysaccharides from C. lentillifera and evaluate its antidiabetic activity. In the initial process of this study, samples were macerated with ethanol (1:10). Then, the maceration residue was extracted with an accumulator at 75 °C for three hours. The crude extract yield was 4.16% based on weight seaweed. Ion chromatography purification with DEAE-Sepharose resin provided a yield of 14.8% of crude extract. The monomer analysis of C. lentillifera from the crude extract and purified extract revealed that galactose monomers were dominant and glucose was a minor component. The total carbohydrate and sulfate contents of purified C. lentillifera were higher than those of crude C. lentillifera. Bioactivity tests revealed that purified polysaccharides had higher antidiabetic activity against α-glucosidase enzyme than crude ones with IC50 values of 134.81± 2.0 µg/mL. Purified sulfated polysaccharides of C. lentillifera could potentially be used as an antidiabetic medication.

Seaweed Industry

Seaweed industry is important in several countries including Malaysia, Japan, Indonesia, and the Philippines. The seaweed, Kappaphycus is widely used in a variety of food products as an excellent nutritional supplement. There are several stages in producing raw Kappaphycus for industry such as cultivation and harvest. Most of these steps follow a traditional way which has been practiced from one generation to another. As seaweed is part of the main ingredients in many final produce, its processing must incorporate cleanliness and quality aspect. Therefore, a focus on Halal is of utmost importance. Halal is a concept that stresses on shariah law and ensuring the utmost quality which benefits most producers especially in food and supplement products. However, the knowledge of Halal is still limited in marine production including seaweed. The seaweed process has gone through numerous stages yet none of them has been checked on its Halalness aspect. This study is to deliberate on the aspect of Halalness for each stage involved, including cultivation and harvesting. To achieve this, observations and literature search were performed and findings showed that there is lack of hygienic practices in handling seaweed production. Therefore, conjoint initiatives among university-industry-government are needed to enhance the value proposition of the seaweed production as it complies with the concept of Halalness. This will contribute towards the development of Halal ecosystem from seed to harvest of quality seaweed production.
