ANALISIS KUALITAS AIR MINUM PADA AIR ALKALI TERIONISASI

Water is needed by humans life, so water quality is a quality requirement of human health. A Few years ago, people are familiar with ionized alkaline water which has a pH of more than 7. Consequently, it is necessary to test the quality of ionized alkaline water following Ministry of Health Regulation (PERMENKES) No. 492 of 2010. Samples were taken from 8 brands of ionized alkaline water in the South Tangerang. The measurement method is procedured with the Indonesian national standard method (SNI). The results of the physical and biological analysis show that 8 brands taken as samples comply with the quality standards with applicable regulations. The result of the chemical show that indicate that 3 samples do not fulfill the PERMENKES requirements, namely pH, pH concentrations ranging from 7.61-8.90 with the required quality standards of 6.5-8.5. Whereas other chemical parameters of Manganese, Iron, Ammonia, Nitrite, Sulfate, Chloride, and Hardness fulfill the specified requirements. The results concluded that only five of the eight brands of ionized alkaline water were suitable for consumption by the applicable regulations.

Greenhouse application of light-drone imaging technology for assessing weeds severity occurring on baby-leaf red lettuce beds approaching fresh-cutting

Aim of study: For baby-leaf lettuces greenhouse cultivations the absence of weeds is a mandatory quality requirement. One of the most promising and innovative technologies in weed research, is the use of Unmanned Aerial Vehicles (or drones) equipped with acquisition systems. The aim of this study was to provide an estimation of the exact weed amount on baby-sized red lettuce beds using a light drone equipped with an RGB microcamera.Area of study: Trials were performed at specialized organic farm site in Eboli (Salerno, Italy), under polyethylene multi-tunnel greenhouse.Material and methods: The RGB images acquired were processed with specific algorithms distinguishing weeds from crop yields, estimating the weeds covered surface and the severity of weed contamination in terms of biomass. A regression between the percentage of the surface covered by weed (with respect to the image total surface) and the weight of weed (with respect to the total harvested biomass) was calculated.Main results: The regression between the total cover values of the 25 calibration images and the total weight measured report a significant linear correlation. Digital monitoring was able to capture with accuracy the highly variable weed coverage that, among the different grids positioned under real cultivation conditions, was in the range 0-16.4% of the total cultivated one.Research highlights: In a precision weed management context, with the aim of improving management and decreasing the use of pesticides, this study provided an estimation of the exact weed amount on baby-sized red lettuce beds using a light drone.

Preliminary study for the creation of a test of pragmatics for Chinese students of Spanish as a foreign language

If the studies of pragmatics of the interlanguage are few, there are still fewer that are carried out for the development of the pragmatic competence assessment in foregin/second language through tests that evaluate pragmatics. There is neither a level test to measure the pragmatic understanding of Spanish nor is there a test specific for students who speak Spanish. The objective of this study is to establish the basis on which the foundations of a future pragmatic test for Chinese students who study Spanish as a foreign language will be established. To achieve this purpose, an ethnographic study that starts from the exemplary generation method and serves to detect the degree of difficulty with which the most common situations of a student’s university life are perceived has been carried out. Due to this preliminary study, in which the same students and some native experts provide us with this information, we can say that the items created and analysed meet the quality requirement, which means that the bases of the pragmatic test are correctly established. All these specifications indicate that and the final questionnaire can now be developed

Development of a Composite from TPS–EVOH–SBR Reinforced with Coconut Fiber

The aim of this research is to obtain a composite made of coconut fiber, thermoplastic starch (TPS), ethylene vinyl alcohol (EVOH), and styrene–butadiene copolymer (SBR), achieving the most significant criteria/attribute determined by users. The tools used were quality function deployment (QFD) and the theory of inventive problem solving (TRIZ). The end result indicated that the quality requirement and most representative attribute for users is the toxicity of the material. Four mixtures were made with different percentages of coconut fiber, TPS–EVOH, and SBR, subjecting them to Fourier transform infrared spectroscopy (FTIR), dynamic mechanical analysis (DMA), and thermogravimetric analysis (TGA). The material obtained complies with the requirements of the Food and Drug Administration (FDA) regarding the nontoxicity of synthetic materials (EVOH and SB) to be used in contact with food (packaging and packaging). The spectra IR of the presence of monomers such as methacrylic acid, 2-hydroxyethyl acrylate, itaconic acid, among others, was not detected due to the humidity of the material. On the other hand, the DMA graphs showed that the mixtures achieved high storage modules (from 1500 to 3000 MPa) at temperatures from −90 to −70 °C, and the TGA thermogram showed that the last material to degrade was SBR at temperatures from 400 to 500 °C.

Employment Prospects of Graduates From Sino-Foreign Cooperative Universities in China

This article aims to examine the employment prospects of graduates from Sino-foreign cooperative universities (SFCUs) compared with those from local Chinese universities. Drawing on the annual employment quality reports released by six SFCUs, the findings indicated that SFCU graduates had distinct advantages in terms of both further study and direct employment. Specifically, the overall employment rate reached 95.84%; over half of the graduates pursued further study abroad in world-class foreign universities, close to one-third continued further studies in elite domestic universities, and one-sixth were employed by transnational or local large organizations. These results suggest that SFCU graduates were equipped with distinct competitive advantages for employment, further supported by an affluent family background and the high-quality requirement for admission. Meanwhile, the findings also raise concerns about brain drain, economic flows, overeducation, reduced entrepreneurial passion, and unemployment dilemma for graduates from lesser known SFCUs.

Variation among Different Growth Stages on Mineral Nutrient Content in Guava Fruits

Guava is one of the most promising fruit crops of India and is considered to be one of the exquisite nutritionally valuable and remunerative crops. We are unaware of any report describing macro and micronutrient dynamics in fruit at different growth stages of guava. For conducting this experiment fruit of variety Allahabad Safeda, L-49, Lalit, Shweta, Arka Kiran, Salithong, Kimchu were collected at different stages like marble, seed hardening and harvest stage for estimation of primary nutrient (N, P, K), secondary nutrient (Ca, Mg) and micronutrient (Fe, Mn, Zn, Cu). As regards the availability of mineral nutrient contents of varieties did not follow definite trend. The nutrient content particularly N, and K were recorded highest at marble stage while as Mg and Ca was accumulated maximum in stone hardening stage and P, Zn, Fe, Cu, Mg and Mn was in harvesting stage. There was least variation was observed in Mg content. Finally, it may be concluded that for the improvement of yields and quality requirement of specific mineral and nutrients is required at different growth stages.
