Soybean (Glycine max (L) Merril) is one of the agricultural commodities to help the food crop of the Indonesian people. Soybeans are one of the commodities that support the implementation of food crop diversification programs and support national food crop security. Increasing soybean productivity in ultisols can be done through liming using eggshell powder. This experiment has been implemented at Jalan Muhammad Hatta, RT 02, RW 08, Pauh, Padang, West Sumatera from October 2020 to March 2021. The purpose is to get the best eggshell powder dose to increase the growth and yield of the soybean on ultisol. The experiment method uses a complete random design (RAL) with 5 levels of eggshell powder treatment 0; 25; 50; 75; 100 g / plant. Data on the observation are analyzed statistically with the F test at a 5% level. If the F count of treatment is greater than the F table, proceed by the test DNMRT at α level of 5% level. The results showed the use of eggshell powder affected the growth and yield of soybean in ultisol to a dose is 25 g /plant.

Bi25FeO40/g-C3N4 composites were synthesized for dechlorination of 2-chlorophenol (2-CP). The characteristic of the obtained products was studied using the X-ray diffraction (XRD), (FESEM) scanning electron microscopy, UV-vis reflectance. The effects of g-C3N4 content, photocatalyst dosage, solution pH, H2O2 on the dechlorination efficiency were investigated, in addition to the reusability of the nanocomposites. The results showed that increasing content of Bi25FeO40 in nanocomposites, from 10 to 30 wt.%, greatly increased the dechlorination efficiency. Bi25FeO40/g-C3N4 20wt.% and initial pH below 6.0 was the optimal conditions for the catalytic dechlorination of 2-CP. About 94.5% of 2-CP were completely removed after 150 minutes reaction at initial pH value of 6.0. The composites were easily separated from the solution by an applied magnetic field. The removal efficiency of 2-CP slightly decreased to 90% when the catalyst was reused in 4 runs. Therefore, Bi25FeO40/g-C3N4 composites can be considered as a promising method for remediation of pollution by 2-CP.

Global climate is warming, and the effects of climate change are associated with many causes; among them are the Greenhouse gas emissions from motor vehicles and factories. The study of exposure to air pollution related to road traffic in Annaba’s region is based on the results of air analyses, which shows that air temperatures are frail, accompanied by a very high humidity due mainly to the presence of the sea and many bodies of water (Fetzara Lake). This can allow the accumulation of certain pollutants such as carbon monoxide and dust (contents of CO and dust exceed the WHO standards), while some pollutants are present in small to negligible quantities such as NO, NO2, and SO. The air quality of Annaba and its surroundings (El Bouni, Sidi Ammar) can be generally described as good. Nevertheless, the existence of strong pollution due to the dust is noted close to the industrial complexes specially El Hadjar.

Tomatoes are one of horticultural commodities which have many benefits for the community, including spices, fruits and vegetables. Tomato cultivation techniques using fruit shade and thinning can be done to overcome the constraints of the mismatch between the quality of products produced by farmers and the quality of products desired by community. Shade has a function to create environmental conditions in accordance with plant conditions, while fruit thinning has a function to maximize the results of photosynthesis so that it can improve the quality of tomatoes. This study aimed to determine the effect of shade and thinning on the result and quality of tomatoes. The study was conducted from January to May 2022 in the Malang, East Java. This research used a Completely Randomized Design with Nested Pattern which consisted of 12 treatments with 3 replications, so that from 36 units of combination treatment. The treatment used was a combination of the use of fruit shade (0,25 and 50%) and thinning intensity (0,3,4 and 5). The analysis of the data used was the F level test of 5%. If the 5% F test had a significant effect, then it was followed by a 5% HSD test. The results showed that the use of fruit shade and thinning significantly affectd the parameters of flower emergence, fruit weight per hectare, fruit weight per fruit, fruit volume, fruit diameter, and no significant effect on the parameters of total dissolved solids.

The results showed that the use of fruit shade and thinning significantly affectd the parameters of flower emergence, fruit weight per hectare, fruit weight per fruit, fruit volume, fruit diameter, and no significant effect on the parameters of total dissolved solids.","PeriodicalId":14038,"journal":{"name":"International Journal of Environment, Agriculture and Biotechnology","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78040672","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A phyA was cloned from Aspergillus niger by reverse transcription polymerase chain reaction. The amplified 1404 bp fragment was cloned in a T/A cloning vector and confirmed by sequencing. The isolated phytase gene showed 99.0 % sequence identity at nucleotide and protein level with Aspergillus niger CBS 513.88 phytase. The amino acid sequence from the phyA cDNA contained the consensus motifs, RHGXRXP and HD which are conserved among histidine acid phosphatases. The phytase cDNA was subcloned in pET28a(+) expression vector and expressed in E. coli. The expression of the gene was confirmed through SDS-PAGE analysis. A 52 kDa protein as per the calculated molecular mass of the translational product of phytase gene was observed in crude lysate of E. coli culture induced with IPTG. The protein was purified using nickel based His-bind resin column and checked on SDS-PAGE. The purified recombinant enzyme showed a single band of 52 kDa protein. The phytase activity of pET-phyA IPTG induced E. coli culture and purified phytase was 383.5 U/ml and 826.33 U/ml, respectively.
