Pembelajaran Sejarah Indonesia Berbasis Peristiwa-Peristiwa Lokal Di Kalimantan Tengah Untuk Meningkatkan Kemampuan Berpikir Kritis
Authors: Hartati Endang
Published: April 2020

Artikel ini membahas pentingnya pengajaran sejarah lokal di sekolah-sekolah yang dikembangkan. Belajar sejarah atau kejadian lokal masih dirasakan sebagai beban oleh para guru. Penyebabnya adalah kurangnya guru kreatif dalam mengembangkan materi sejarah, mereka berfokus pada materi yang tercantum dalam silabus sejarah pengajaran dan minimal atau tidak ada sumber sejarah lokal yang dapat digunakan oleh guru sebagai bahan ajar di sekolah. Makalah ini berfokus pada urgensi belajar sejarah lokal, yang terintegrasi dengan pengajaran sejarah di Indonesia. Lebih banyak penelitian dilakukan secara khusus terhadap karakter dan peristiwa yang terjadi di wilayah Kalimantan Tengah. Dalam penelitian ini, penulis menunjukkan bahwa di Kalimantan Tengah harus ada banyak karakter dan acara lokal yang harus mendapat perhatian serius dari semua pihak untuk dikembangkan dalam pengajaran sejarah di sekolah. Hal ini sangat penting mengingat pengembangan karakter harus dimulai dari kesadaran akan identitas mereka sebagai bagian dari sejarah Indonesia. Oleh karena itu, perkembangan sejarah lokal merupakan bagian dari pengembangan identitas sebagai bangsa Indonesia.

Authors: AJAO Abdullahi , AWE Sunday
Published: April 2020

The present study evaluates the bioremediation potential of indigenous bacterial species isolated from dye-contaminated soil samples from small dyeing outlet located in Ilorin. The water pollution index was estimated based on the physicochemical characteristics and heavy metal concentrations of the raw (Day 0) and treated textile wastewater such as pH, biochemical oxygen demand-5, chemical oxygen demand, total suspended solids and total dissolved solid with mean values of 8.85±0.45 mg/L, 1200±21.3 mg/L, 2440±31.3 mg/L, 1660±17.2 mg/L and 2650±28.1 mg/L respectively, similarly, Lead was the most abundant heavy metal detected in the sample while Cadmium concentration was the lowest with the mean values of 3.52±0.00 mg/L and 2.18±0.00 mg/L respectively. The bacterial strain with highest dye decolorization capacity was screened and identified as Bacillus licheniformis ZUL012.The isolate was consequently used for the bioremediation of the wastewater over a period of 10 days. The results showed an incredible reduction in the physiochemical characteristics and heavy metal concentrations of the textile wastewater in the following ranges (8.85-6.55), (1200-300) mg/L, (2440-518) mg/L, (1660-666) mg/L and (2650-920) mg/L with the highest removal efficiency of 75 %, 78 %, 60%, 65%, recorded for biochemical oxygen demand, chemical oxygen demand, total suspended solid, total dissolved solid, respectively while that of heavy metals such as lead, cadmium, chromium and nickel were 80 %, 60 %, 67 %, 72 % reduction, respectively. Laccase and Azoreductase activities tend to decrease as the pH gradually moved towards acidic condition during the bioremediation process. Toxicity of the treated effluent was assessed using Maize and Bean seed germination test. Conclusively, these research findings can serve as a framework for the outlet design of wastewater treatment plant for local textile outlets.

Imam al-Ghazali mengatakan, tanda-tanda bahwa Allah meninggalkan hambanya adalah apabila ia berbuat sesuatu yang tidak berguna. Dan barang siapa yang menghabiskan umurnya tanpa dipergunakan untuk beribadah kepada Allah, maka pantaslah ia mengalami kesedihan yang lama. Serta barang siapa yang umurnya lebih dari empat puluh tahun tahun sedangkan amal kejelekannya lebih besar dari amal kebaikannya, maka orang tersebut bersiap-siaplah menuju neraka. Dan, parahnya lagi, manusia yang paling menderita siksaan Allah pada hari kiamat adalah orang-orang yang pintar namun ilmunya tidak bermanfaat. Begitu pentingnya pendekatan dalam pembelajaran, agar seseorang berhasil dalam proses pembelajar serta ilmu yang dimiliki tidak sia-sia dan  bisa berguna serta bermanfaat baik untuk dirinya dan juga untuk orang lain.

Published: April 2020

Pendidikan merupakan bagian yang sangat penting dalam kehidupan manusia. Karena hanya dengan pendidikanlah kita mampu untuk menerjemahkan nilai-nilai, gagasan, sikap dan tindakan sosial yang mencerminkan kehidupan yang bermoral dan bermartabat. Tanpa pendidikan kita tidak bisa menjadi manusia yang beradab. Dengan pendidikan manusia dapat mengembangkan segala potensinya untuk menjadi manusia yang cerdas dan beradab. Untuk mewujudkan masyarakat yang beradab, penulis menggunakan teori Perubahan Sosial sebagai pisau bedahnya. Pada teori tersebut akan dijelaskan bagaimana pendidikan dapat mempengaruhi individu dalam masyarakat yang nantinya akan memberikan efek pada perubahan teknologi, perilaku, sistem  sosial, dan norma. Pada intinya teori Perubahan Sosial memberikan asumsi bahwa setiap masyarakat berpotensi untuk berubah, baik perubahan tersebut bersifat positif ataupun negatif. Melalui peran pendidikan inilah diharapkan masyarakat bisa berubah menjadi masyarakat yang beradab.

Xylocopa sonorina Smith, 1874 from Vancouver, British Columbia, Canada (Hymenoptera: Apidae, Xylocopinae) with comments on its taxonomy
Authors: Sheffield Cory , Heron Jennifer , Musetti Luciana
Published: April 2020

Only one species of large carpenter bee,Xylocopa virginica(Linnaeus, 1771), has been recorded from Canada, albeit restricted to southern Ontario and Quebec. However, a single female specimen identified by Hurd in 1954 asX. varipunctaPatton, 1879 from British Columbia is in the C.A. Triplehorn Insect Collection at The Ohio State University (OSUC), suggesting that this species was accidentally introduced into coastal western Canada. As wood-nesters, many large carpenter bees are likely capable of expanding their range great distances by natural and unnatural transport methods while nesting inside suitable substrates, the presumed mode of transport into western Canada, and likely elsewhere. The ease at which the nests are transported has likely contributed to the nomenclatural and distributional ambiguity surrounding this species due to morphological similarities of specimens from North America, Hawaii, and several South Pacific islands.

By comparing DNA barcodes of specimens from the western United States to specimens from Hawaii, we confirm the early opinion of P.H. Timberlake (Timberlake 1922) that specimens long established on the Hawaiian Islands are the sameX. varipunctafrom continental North America. Furthermore, these DNA barcode sequences also match those of specimens identified asX. sonorinaSmith, 1874 from the French Polynesian and Samoan Islands, thus fully supporting the opinion of Groom et al. (2017) that all are likely conspecific. AsX. sonorina, a species described from and likely introduced to Hawaii is the oldest name available,X. varipunctais here placed into synonymy. Additional research will be needed to trace the timing and pathway of introduction and establishment ofX. sonorina; it is presumed that the species is native to the southwestern United States but has been established in Hawaii since the mid-1800s. It is also established in French Polynesia, the Samoan Islands, and likely other south Pacific islands, with additional records of occurrence from Java, New Zealand, and now Canada.
The negative effects of dry eye disease on quality of life and visual function
Authors: O.D Lee W. Guo , AKPEK Esen K.
Published: April 2020

In recent years, dry eye has become a hot topic within ophthalmology and optometry, especially in regards to new frontiers in treatment modalities which include novel devices, procedures, and medications. However, some of the more understudied areas in dry eye involve its impact on quality of life. Although ocular discomfort symptoms are well known to be associated with dry eye, its negative effects on visual function remain underrecognized. This paper reviews these topics within the currently published literature to heighten awareness among clinicians.
Refractive Index of the Human Corneal Epithelium and Stroma
Authors: Patel Sudi , Marshall John , Fitzke Frederick W
Published: April 2020

ABSTRACT

BACKGROUND: The refractive index of the cornea must be determined to optically perfect keratorefractive procedures. There are very few empirical measurements of the human corneal refractive index described in the literature. Throughout its depth, the cornea demonstrates regional variations in physiological properties such as swelling/de-swelling characteristics. These properties suggest there may be a difference in the refractive index between the anterior and posterior corneal surfaces.

METHODS: The refractive index of the human corneal epithelium of 10 eyes was measured, in vivo, using a modified hand-held refractometer. The refractive indices of the anterior and posterior surfaces of the bare stroma of fresh human corneas were measured using a bench model Abbe refractometer.

RESULTS: The mean refractive index of the epithelium, stromal anterior and posterior surfaces were 1.401 (SD ± 0.005), 1.380 (SD ± 0.005), and 1.373 (SD ± 0.001) respectively.

CONCLUSIONS: The refractive index of the cornea is not uniform. The calculated dioptric power of the corneal epithelium is approximately -1.40 diopters (D). The varying refractive index does not significantly affect the total dioptric power of the cornea. The varying refractive index of the cornea has the potential to significantly contribute to the overall optical performance of the eye in relation to refractive surgery. The results should be incorporated into mathematical models, comparing and contrasting the optical performance of the eye before and after surgery. [J Refract Surg. 1995;11:100-105.]

Published: April 2020

Peat can be used as a natural adsorbent due to its humic acid content having various active functional groups such as carboxylates and hydroxyl groups. Peat soil samples obtained from Pelalawan district, Riau province of Indonesia were selected and their adsorption capacities were investigated using Mn(II) solution as a model solution. The raw peat samples were first prepared by drying at 110°C for 12 h. The adsorption experiment was conducted in batch test using Mn(II) solutions for 360 mins at pH of 5.2 as optimum conditions. The peat samples were analyzed using the Fourier Transform Infrared Spectroscopy, Surface Area Analysis and Scanning Electron Microscopy- Energy Dispersive Spectroscopy. The obtained adsorption data were fitted using Langmuir, Freundlich and BET isotherm models. It was found that the adsorption data followed the Langmuir isotherm model with correlation coefficients (R2) ranging between 0.9866-0.9997 and the adsorption capacities were between 11.99-22.94 mg/g.

Published: April 2020

Herein, we report a facile synthesis of zinc oxide-reduced graphene oxide (ZnO-rGO) hybrid materials by two-step method. Firstly, rGO was synthesized by using graphite powder mixed with sodium nitrate, sulfuric acid and potassium permanganate via Hummers method. Synthesized rGO were dispersed in ethanol by ultra-sonication for a designated time period. Then, zinc oxide (ZnO) powder was added into rGO-ethanol solution and transferred into Teflon-lined stainless steel autoclave. The ZnO-rGO was produced by hydrothermal method at 180 °C for 120 and 180 min (here after referred to as ZnO(120)-rGO and ZnO(180)-rGO, respectively). The morphological and crystalline structures of synthesized rGO and ZnO-rGO were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray diffraction (XRD). Synthesized ZnO-rGO was exposed to 100 parts per million (ppm) nitrogen dioxide (NO2) gas at room temperature, 50 °C and 75 °C for testing its sensing performance. The results show that ZnO(180)-rGO hybrid materials exhibit high response to NO2 gas at 50 °C and 75 °C. The electrical resistance of ZnO-rGO sensors decreased when the sensors responded to NO2 gas, indicating a p-type behavior. Moreover, the ZnO-rGO hybrid materials can detect 100 ppm NO2 gas with an operating temperature limit at 50 °C. The results imply that synthesized ZnO-rGO hybrid materials could be used as gas sensing device for ppm-level NO2 detection at low temperature and consume low power.

Published: April 2020

Stainless steel is widely utilized due to its higher corrosion resistance and gloss than ordinary steels. However, the applications of stainless steel are still limited because of its low surface hardness. Graphene is a superb material, which has an intrinsic strength of 130 GPa. In this report, the growth of high quality graphene on S304 stainless steel by chemical vapor deposition using acetylene gas as a carbon source is demonstrated. The surface hardness of stainless steel after growing high quality graphene is investigated by nanoindentation technique. High quality graphene can increase the surface hardness of stainless steel from 1.54 GPa to 10.08 GPa. Moreover, the effect of graphene quality on the surface hardness of S304 stainless steel is studied. High quality graphene grown by CVD using acetylene gas as a carbon source can increase the surface hardness of stainless steel about two times more than low quality graphene grown by using methane gas.

The present work, focused on the Atmospheric boundary-layer airflows and their interactions with obstacles, particularly in relation to urban air quality, therefore two passive control methods are represented in barriers solid LBWs (Low Boundary Walls) and crossings under building, in order to investigate the dynamic impacts in the center urban canyon road. These passive control solutions are designed for reducing the concentrations airflows polluted necessary, while a correct air quality in the urban areas. For these reasons, the passageways under building and LBWs models have been performed with a two dimensional numerical ANSYS-CFX code, rendering it ideal for examining the concentration distribution within street canyons of H1/H2 = 0.5-1-1.5 and the dynamics effects of pollution concentrations of vehicle emissions of sulfur hexafluoride (SF6), which it is taken as a tracer gas within the symmetrical urban street canyon. However the Reynolds-averaged Navier–Stokes equations and the k-ɛ turbulence model are applied in order to close the equations system. The results achieved are evidence about the diminishing of the pollutant concentrations normalized in in the leeward and windward of the urban street canyon

Published: April 2020

This paper proposes a new approach for traffic sign recognition using images captured by a low-cost mapping system. The proposed approach applies the SIFT algorithm to extract keypoint features that are used to evaluate the correspondences between a road image containing one or more plates and the images of traffic signs (templates). The BBF algorithm was used to efficiently evaluate the correspondence between the SIFT features. Finally, we propose a new algorithm to filter only the pairs of keypoints (image-template) that are compatible as well as the orientation and positioning.

The objective of this paper is to provide new research on the linkages between voltage asymmetry, energy efficiency, and resource efficiency to inform policymaking in this area about the possibilities of electricity saving potential. Asymmetry voltage coefficients value in Ukrainian grid were experimentally identified based on assessments of 23 Ukrainian companies during 2016-2018. It was estimated, that 26 % of transformers have asymmetry voltage coefficient of reverse sequence lower than 2 % and 12 % of transformers have asymmetry voltage coefficient of zero sequence lower than 2 %. The estimated resource saving potential for Ukrainian power generating plants is up to 1’978 GWhel/a, which is up to 1.5 % of total electricity produced. Equivalent reducing electricity generation at coal power plants could prevent emissions up to 292.79 t/a of ash emissions; 733 kt/a of CO2 emissions; 5.9 kt/a of SOx emissions; 2.9 kt/a of NOx emissions; 9.03 m3/a of nuclear waste.

Tetracycline wastewater excess active sludge TEAS was studied for the possibility of heavy metal ions adsorption and barrier materials in the landfill. TEAS was characterized by SEM, element analysis, TGA and FT-IR techniques. The characterization of TEAS demonstrated mounts of remaining hypha residues existed in sludge. High-temperature drying of sludge reduced the potential risk of remaining Tetracycline bleaching. The Adsorption thermodynamics study of TEAS to the Cu2+, Ni2+ ，and Cd2+ indicated a spontaneous and endothermic nature of the adsorption process. The best equilibrium data was given by Langmuir isotherm, and the maximum adsorption capacities were 18.484，14.837 and 9.116 mg/g for Cu2+, Ni2+ and Cd2+, respectively. The kinetic data of adsorption were described by a pseudo-second-order equation, indicating their chemical adsorption. The main mechanism of metal biosorption was cation exchanged is expected that TEAS could be used as a promising co-disposal and attenuation material in the landfill to hinder the heavy metal solution into Landfill leachate.

Published: April 2020

Urban open spaces (e.g. urban parks) play a pivotal role in improving the quality of life of city dwellers through accommodating various physical and social activities, while further creating social coherence for sustainable development. Due to the shortage of open green spaces in the city, caused by rapid urbanization in developing countries, some big, long-standing urban public spaces such as district parks have been retained, and improved to serve as the main public space for local people. However, such spaces commonly provide outdated, low quality facilities that discourage people from using the park. To satisfy users’ needs, local governments have launched campaigns to improve parks based on the ideas of domestic or foreign designers. The purpose of this research is to explore different behaviors of residents in an open space in Da Nang (Vietnam) which can support the future development and improvement of local open space in accordance with environmental behavior theory. User behaviors were identified and categorized based on their activities in the open space, collected using the place-centered behavior mapping method. Results of the statistical analysis revealed that this open space could be divided into three types, each of which had four dimensions: public facilities setting; openness; accessibility; and recreational facilities. The findings showed some aspects that need to be considered during the development process of open space as follows: 1) increasing the quantity and quality of public amenities; 2) separating accessible space and/or buffer space from already used space inside the park, particularly in the entrance zone; 3) providing space adjacent to the lake; and 4) removing obstacles (e.g. walls around the park) to give a clearer view from inside the park to the streets outside and vice versa. Also, the calculation model of evidence-based designs provides input data for re-planning or creating public space/parks to help designers, planners and authorities improve or design better open spaces in the future.
Important pharmacogenomic aspects in the management of HIV/AIDS

Published: April 2020

In managing HIV/AIDS with highly active antiretroviral agents, the historical therapeutic aim remains to maintain the plasma concentrations at a level above the half maximal inhibitory concentration (IC50) required for 50% inhibition in viral replication. Concentration dependent toxicity is often observed in patients with elevated drug exposure and high peak plasma levels in lieu of accurately calculated drug dosages. Similarly low plasma concentrations are frequently witnessed in individuals receiving adequate dosage regimens. Pharmacogenetic variations in drug metabolizing enzymes may contribute to this phenomenon. Over the last decade, knowledge about the role of pharmacogenetics in the treatment and prediction of ARV plasma levels have increased significantly. However, the extent of these genetic variations remain largely unknown in the South African population, which has sparked a renewed enthusiasm for local pharmacogenetic studies.

Background: The Ward Based Outreach Team (WBOT) is an organised team approach to a healthcare system based on the principles of epidemiology, primary health care, preventive medicine and health promotion. Globally, it has become a primary care response to many health challenges such as universal health coverage. The beneficiaries are community members, also referred to as households.Methods: The study assessed the awareness of the WBOT and the services offered by the programme in the Tshwane health district of South Africa. This was a cross-sectional survey conducted in all seven sub-districts of the health district. The health district is further sub-divided into 150 health wards. Eighty-five health wards were randomly selected for the study. Using the sample size calculator, with a confidence interval of 5% and confidence level of 99%, the sample size of participants was 654. However, during the data collection process there was over-sampling of up to 764. Participants were recruited by convenience sampling. Data were collected between October 12 and December 3, 2015, using a pre-piloted, structured questionnaire administered by 14 trained field workers.Results: The study obtained 6 288 responses from the 764 participants. The responses were grouped into two sections, ‘Yes’ and ‘No’. A summary of the responses showed that the number of ‘yes’ responses, the number of participants who were aware of the WBOT and the services offered by the programme were higher than the number of participants who were unaware of the programme. The figures were 5 590 (88.8%) ‘yes’ responses and 698 (11.1%) ‘no’ responses.Conclusion: In summary, the awareness of the WBOT and the services offered by the programme in the Tshwane health district, South Africa is evaluated to be 88.8%.
