Authors: Gustiani Sri , Simanjuntak Tiur , Risnawati Risnawati , Rahma Munaja
Published: August 2019

This research is to know teachers’ perceptions on methods of teaching English for classes with mixed-English proficiency students: primary, elementary, intermediate, and advance levels.  These methods were some differentiated instructions taught in training to teachers of English as a community service activity which conducted to the teachers of English at Lembaga Bahasa (LB) Bagus Palembang. In this training, the participants learned the methods because they did not get the knowledge in their pre-service teacher training. They only had teaching methods for classes with one level of English proficiency. After they completed the training, they were monitored during the methods application in order to find their perceptions on teaching such class. The data were gathered via observations in the class during the monitoring. The observation data were, then, matched to the data from semi-structured interviews to know the participants’ perception on the methods in their classes.  The research revealed that the methods were proven to increase students’ participation in class with notification to high proficiency ones. However, it was not possible to suggest other best practices for dealing with all students in that class because not all practices work in a mixed-English proficiency class.

Hiperrealitas Sosok Suami Tenaga Kerja Wanita (TKW) Dalam Sinetron Dunia Terbalik Di RCTI
Authors: Astagini Nuria , Nurhidayah Fitriyah
Published: August 2019

Bagi sebagian perempuan Indonesia, bekerja menjadi Tenaga Kerja Indonesia (TKI) luar negeri adalah salah satu cara untuk membantu keluarga keluar dari kemiskinan. Sayangnya perjuangan kaum perempuan yang bekerja sebagai TKI ini kadang tidak didukung oleh suami dan keluarga mereka. Banyak suami TKI yang menyalahgunakan kepercayaan dari istri –istri mereka, menelantarkan keluarga; bahkan menggunakan uang kiriman dari sang istri untuk berbagai perilaku menyimpang. Melalui sinteron “Dunia Terbalik” yang ditayangkan di RCTI ini kita diajak untuk melihat sosok suami TKI yang sangat bertolak belakang dari suami TKI pada umumnya. Sinetron ini menggambarkan suami yang dengan ikhlas menerima tugas sebagai “bapak rumah tangga”. Hal inilah yang disebut Jean Baudrillard sebagai hiperrealitas, dimana simulasi dari realitas menciptakan realitas baru atau hiperralitas yang menyelubungi realitas yang sebenarnya. Para suami diperlihatkan ikhlas menggantikan peran istri dan meletakkan kekuasaan mutlak di tangan istri. Hiperrealitas yang diperlihatkan pada sinetron ini dapat menjadi titik awal yang memunculkan konsep kesetaraan gender, serta berkontribusi untuk menghapuskan stigma negatif yang melekat pada kalangan TKI serta keluarga mereka.Kata Kunci : hiperrealitas, gender, peran, TKW, sinetron, stigma, negatif

Published: August 2019

The study was conducted to determine the possible ameliorative activity of coconut oil on the toxic effects of untreated refinery effluents on the ovaries of Norwegian rats. Three experimental groups of 10 rats each were used for the study; all animals had feed and water ad libitum. Group 1 was untreated and served as the control group, Group 2 was treated with 2 ml of untreated refinery effluent daily PO and group 3 was treated with 2 ml of untreated refinery effluent and 2 ml of coconut oil daily PO for 9 weeks. Every 3 weeks 2 rats in each group were euthanized with chloroform and ovarian tissues were surgically harvested; tissue concentration of heavy metals was assayed and histology was carried out. Treatment was discontinued at nine weeks and rats in group 2 and 3 were designated groups 4 and 5; allowed a 21 days resting period after which they were euthanized, ovaries surgically harvested and assayed as well. Results indicate that changes in ovarian tissue concentration of Chromium and Lead in the treated groups were of statistical significance (P ≤ 0.05) compared to control. Results also showed that rats treated with coconut oil as abatement had normal histological architecture. Coconut oil had ameliorative effects on the ovary of rats intoxicated with refinery effluent and the ovaries returned to normal activities within 21 days post exposure.

Authors: Epuh E. E. , Sanni K. A. , Orji M. J.
Published: August 2019

Productivity through groundwater is quite high as compared to surface water, but groundwater resources have not yet been properly exploited. The present study is used to delineate various groundwater potential zones for the assessment of groundwater availability in Lagos metropolis using remote sensing and GIS and hydrogeophysics techniques. Landsat 8, SRTM, geological, soil, and rainfall data were used in the study to prepare various thematic maps, viz., geomorphological, slope, soil, lineament density, rainfall and land use maps. On the basis of relative contribution of each of these maps towards groundwater potential, the weight of each thematic map have been selected and assigned to each map. Hydrogeophysics investigation using Vertical Electric Sounding (VES) was applied to validate the remote sensing and GIS results. All the thematic maps have been registered with one another through ground control points and integrated using the weighted overlay method in GIS for computing groundwater potential index. Based on the methological approach, the ground water potential zones were delineated. The results showed that there are five categories of groundwater potential zones within the study area in which percentage values were contained in each of the categories thereby making major portion of the study area “high” and “moderate” prospect while a few scattered areas have “low” prospect. The very high potential areas are mainly concentrated along the River Alluvium while the “very low” prospect are majorly where there is sand and clay. The best groundwater potential zone is in the southern part due to the presence of fractures, swamp soils which have high infiltration ability and the presence of waterbody which is chiefly accountable for the groundwater recharge in any area. The VES data showed the depth of the aquifer for good water and the polluted aquifer within the study area.

Published: August 2019

The volume of traffic generated by land-use pattern varies during different periods of the day but there is usually a predictable pattern of such traffic volumes. Most often, the structure of urban land-use fails to provide easy and convenient traffic movement, which in the case of the study area is usually that of vehicles and pedestrian traffic. The fact is that Minna is presently experiencing rapid urban growth. Both the authorities and citizens seem to simply ignore this and its impact on human existence. The research is based on Road Traffic Network Analysis in Minna, to develop a road network map and determine the causes of Traffic Congestion in Kpakungu specifically. Quickbird satellite imagery was used in analyzing and mapping out the existing road network within the study area. Field survey aspects involving measuring of roads, traffic count, coordinates captured were also undertaken. It was discovered that the causes of the traffic pressure in the study area was as a result of the relocation of Federal University of Technology, Minna to its permanent site in Gidan Kwanu and the relocation of National Examination Council(NECO) Headquarter. Majority of the traffic pressure in the area were as a result of vehicles coming from Maikunkele, Bosso, Maitumbi, Minna central, Dutsen Kura, Chanchaga, Tunga, Sahuka-kahuta and BarikinSale going to Bida, Gidan-Kwanu or NECO office. It was concluded that alternative roads should be provided for vehicle diversion to limit the congestion of traffic on the road.

This study evaluated soil organic carbon stock and its relationship with some soil micro- bial, physical and chemical properties. The soils were Alagba, Orlu, Ahiara and Kulfo series located in two (2) locations within Edo State namely; Nigeria Institute for Oil Palm Research (NIFOR), Benin City, (latitude 06.33’ to 06.47’N; longitude 05.37’E to 05.46’E) and Rubber Research Institute of Nigeria (RRIN), Benin City, (latitude 06.08’N to 06.11’N; longitude 05.34’E to 05.38’E). With the aid of soil maps, in each of the soil types, random auger samples were collected at a soil depth of 0-30 cm. Similarly, core samples were taken from the same point where auger boring was made. The results obtained from the study indicated that there were significant differences between the various soil types and soil properties. The study revealed that most of the soils were dominated by sand in Texture. The results further revealed that there were considerable variations among the soils in soil organic carbon stock contents. For example, NIFOR location had mean values ranging from 14.76 g/kg to 86.16 g/kg. While that of RRIN ranged from 26.28 g/ kg to 104.6 g/kg. Total bacteria count ranged from 16.07 cfu/g x 103 (Kulfo soils) - 24.20 cfu/g x 103 (Alagba soils) and Total fungi count ranged from 10.00 cfu/g x 103 (Kulfo soils) - 15.00 cfu/g x 103 (Alagba soils) respectively as recorded for NIFOR soils (location 1). While, pH value ranged from 5.4 (Ahiara soils) - 6.2 (Orlu soils), Soil organic matter ranged from 38.38 g/kg (Kulfo soils) - 55.08 g/kg (Alagba soils). Total bacteria count ranged from 16.00 cfu/g x 103 (Ahiara soil) - 26.00 cfu/g x 103 (Alagba soil) and Total fungi count ranged from 10.00 cfu/g x 103 (Ahiara soil) - 22.00 cfu/g x 103 (Orlu soil) respectively as recorded for RRIN location.
Enhancing maize (Zea mays l.) growth and nutrient uptake via application of water hyacinth (Eichornia crassipes [Mart.] Solms) compost and inorganic nutrients
Authors: C.T Atere , A. olayinka
Published: August 2019

A soil culture experiment was conducted in the screenhouse to assess the growth response of maize to water hyacinth compost application rates and their residual effects. Water hyacinth (Eichhornia crassipes [Mart.] Solms) compost, namely, 2.5 t ha-1(W1) and 5.0 t ha-1 (W2) with and without fortification with fertilizer, F [N (25 kg ha-1 as urea) and P (26 kg ha-1 as SSP)] were mixed with portions of 5 kg soil and used to grow maize. At eight weeks after planting in each of two con- secutive cropping, plant heights, biomass dry weight and their nutrient contents were determined. Soil was also sampled from each pot for chemical analyses. Compared with the control, available P and exchangeable K were increased (p<0.05) by W2F (27%) and W2 (43%), respectively. Similarly, W2F and W2 increased SOM by 86 and 107% (p<0.05), respectively, while W2F, W2 and W1F increased exchangeable Ca between 8 and 10% (p<0.05). Treatments W2F, W2 and W1F increased plant heights by 35–40% while W2 and W2F increased the dry matter yield by 72 and 75% (p<0.05), respectively. Further, sole compost or its organo-mineral form increased the tissue contents of N (98–141%), and K and Mg (103–280%). The tissue content of Ca was also increased (p<0.05) by W2F. Residual effects of the soil amendments were also significant on most tested soil and plant parameters. It was concluded that soil nutrient status, maize agronomic and nutrient uptake parameters were improved by the application of water hyacinth compost with and without inorganic N and P. The rate of 5.0 t ha-1 of the sole compost and its organo-mineral form proved superior in enhancing maize growth and soil nutrient status.

Different tillage practices are being employed by the farmers of Jigawa state, and as such, there is a need to determine its influence on some physical and chemical properties, so that farmers will base their choices on scientific facts rather than assumptions. An experiment was conducted to investigate the effects of three tillage practices (TP) on soil properties in Federal University Dutse, Teachings and Research farm, Jigawa State. The TP adopted are conventional tillage (CT), reduced tillage (RT) and zero-tillage (ZT). Samples were collected at a depth of 0 -20 cm for the chemical and other physical properties determination, while core samplers were used for bulk density (Bd) determination. All data collected were analyzed using Statistical Analysis Software (SAS and analysis of variance (ANOVA) was used to determine the significant tillage effect on the parameters measured at 5% level of significance and the means were separated using Least Significance Difference (LSD). The results showed that the soil texture of the study area was sandy loam. ZT differed significantly from other TP with higher Bd value of 1.51 Mg m-3, lower porosity (42.7%), and lower moisture content (10.3).

Abstract - PT. Perkebunan Nusantara IV Air Batu (PTPN IV) is a government-owned oil palm plantation that is engaged in the production of palm fruit, oil palm plants will grow well and produce optimally if the plant is protected from disease. However, there is an imbalance where every year palm oil needs increase, while oil palm production decreases. This is due to lack of understanding of plantation assistants on the types of diseases found in oil palm plants which can cause continuous damage to oil palm plants. The Bayes method is one method that is suitable for selection, because the Bayes method is a good method in machine learning based on training data using conditional probabilities as the basis. With this expert system it is expected that plantation assistants can find out the type of disease and its solution quickly so that the problem of decreasing oil palm production can be overcome. The results of the research in the form of an expert system diagnose the disease of oil palm plants using the Android-based bayes method thus, this application can be used to analyze diseases using cellular phones.

Published: August 2019

Abstract - Along with the development of communication technology human needs in the use of technology are increasing, especially in data storage. One way to improve security for data is by using cryptographic methods. RSA Algorithm (Rivest Shamir Adleman) is one method in the branch of cryptography, where RSA is a type of asymmetric cryptography that uses 2 keys, namely public and private keys. The problem of increasing the security of the public key and private key in RSA (Rivest Shamir Adlema) is that the Linear Congruential Generator (LCG) method is needed, LCG is used to generate a set of random numbers to n, where a set of random numbers will be taken that have a number value prime. One method for generating prime numbers is The Sieve Of Eratosthenes algorithm, The Sieve Of Eratosthenes algorithm is a classic algorithm for determining all prime numbers until the n-number is specified. The way the The Sieve Of Eratosthenes method works is to eliminate numbers that are not prime numbers, resulting in a collection of prime numbers. The prime number generated by the The Sieve Of Eratosthenes algorithm will be used for the public key and private key in the RSA criterion. Keywords - RSA, LCG, The Sieve of Eratosthenes.
