Treatment of Synthetic Dairy Wastewater Using Disposed Plastic Materials as Trickling Filter Media: Optimization and Statistical Analysis by RSM

Shuokr Qarani Aziz and Sazan Mohammed Ali

Abstract This work was aimed to study the treatment of synthetic dairy wastewater by using the biological trickling filter technique. Synthetic dairy wastewater was prepared in the laboratory by using an organic source of commercially powdered starch. Experiments were designed, conducted, and results were analyzed by using response surface methodology (RSM). The variables were filter media depth, size, and types such as river rocks, disposed plastic caps, and parts of polyvinyl chloride pipe. The responses were chemical oxygen demand (COD), electrical conductivity (EC), turbidity, and colour. Optimum results obtained by RSM for the disposed plastic cap filter media with medium size of 5 cm and 60 cm depth were chosen as optimum conditions. The optimum removal values of COD, EC, turbidity, and colour for disposed plastic cap media were 90.19%, 5.21%, 88.37%, and 84.23%, respectively.

Ulfiah Nurhikmah, Yusran Jusuf

Abstract Forest management area is now very important to be discussed, with some programs issued by the government do not have to make forest governance good. Behind the many existing programs cannot be separated by the conflicts that occur therein. Forest management Unit Jeneberang II became one of the programs issued by the Ministry of Forestry to realize good forest governance in the region of South Sulawesi province. We review transformation conflicts occurring in forest management by creating conflict histograms and analyzing the transformation of each conflict at any time using live interviews and relevant document searches. We found that there was a common conflict known to society called a manifest and a closed conflict called latent. The current threat of conflict is a latent conflict that circulated widely in the area of forest management, such as the possession of land performed by certain parties.

Estimating Grazing Capacity for Desert Rangelands of Wadi Hederbah in Southeastern Egypt

Ahmed H. Mohamed, Mohamed A. El Shesheny, and Hassanein S. Badawy

Abstract Temporal and spatial variability in desert rangelands forage productivity had made estimating grazing capacity and stocking rate complicated procedure particularly under the nomadic pastoralists in developing countries. This experiment was conducted at Wadi Hederbah in southeastern Egypt with the objectives of evaluation rangeland condition, determination of rangeland productivity and evaluation of the nutritive value of the primary plant species, and estimation of rangeland grazing capacity for the area. The study area was mapped using ArcGIS and classified into four sections according to elevation levels. Rangeland vegetation survey was conducted at the study area in the spring of 2014 and spring of 2015 and vegetation attributes were determined. Chemical composition and In Vitro nutritive values of rangeland plant species common on the study area were estimated using common procedures. Appropriate methods were followed to calculate rangeland condition and grazing capacity for the study area and maps of forage productivity, rangeland condition, and grazing capacity were produced for the study area. Results indicated that there were 8 plant species including, Acacia raddiana, Aerva javanica, Alhagi maurorum, Lycium shawii, Maerua crassifolia, Panicum turgidum, Zygophyllum album, and Zygophyllum simplex. Six of them are palatable to the common livestock types in the region, and two were not palatable. Results also showed that Panicum turgidum had the highest dry matter forage production of 85.9 kg DM/ha and 75.25 kg DM/ha for spring of 2014 and spring of 2015, respectively compared with the other plant species. Moreover, Alhagi maurorum, Maerua crassifolia and Aerva javanica had higher (P<0.01) values of ME, IVDMD and IVOMD than that in Panicum turgidum, Acacia raddiana and Lycium shawii. Rangeland condition of the study area ranged between poor to fair rangeland condition. Grazing capacity as dry sheep equivalent for 6 months period for the study area were 377, 114, 253, 144 DSE for section 1 to 4, respectively. Our approach and findings regarding estimating and mapping grazing capacity would have management implication for the sustainable desert and arid rangeland development and management.

A.Erna Sri Mustafa, Arman, Sitti Nurani Sirajuddin, NurdwianaSari Saudi

Abstract The aim of this study is to (1) identify various transaction costs incurred by the farmers and (2) look at the effect of transaction costs from striped buffalo in the market. To achieve these objectives, qualitative and quantitative approaches are used with multiple linear regression analysis tools. The research was conducted from April to July 2019 in the North Toraja Regency by taking a sample of 30 breeders who specialized in selling striped buffalo. The results showed the largest transaction costs incurred by farmers was a brokerage fee of Rp.5,000,000/buffalo/transaction (12.30%) and the least cost is the transportation fee of Rp.2,100,000/month (0.53%). The amount of the brokerage fee is due to the information gap from the lack of education and weak negotiating abilities. The results of the regression analysis showed that brokers significantly affected the market of striped buffalo with a sig value of 0.006.

Molecular identification of oral microflora associated with different health conditions

Mohammed Alassiri, Mohamed Abu-Zeid, Mohammed H. Mutwakil, Mohamed Morsi M. Ahmed

Abstract The current study aims to detect and identify microbes in human saliva microbiota of medical students and employees and correlate species with health conditions, smokers (S), influenza infected (I) and normal group (N). A total number of 100 samples were collected from medical school male students and employees' volunteers at Jeddah, Saudi Arabia in March 2017. The molecular 16S rRNA gene sequencing indicated a broad diversity of bacteria representing two different phyla; Firmicutes such as Staphylococcus and Proteobacteria such as Klebsiella species. High dominance among the identified genera of Staphylococci 30%, followed by Klebsiella 15%, while unculturable species showed 50% dominancy. There was a 100% correlation of the genera Klebsiella with smokers' group. Staphylococci genera which were dominant in the normal and influenza-infected group disappeared completely in the smoker's group. Comparing the morphology data observed with molecular 16S rRNA identities, the results were in agreement with the genera identified. Our study suggests that smoking alters bacterial acquisition and oral mucosal colonization in favor of periodontal pathogens. Awareness should be created for the public on the health implication of smoking and poor oral practice.
