Published: October 2020

The aim of this research was to gain deeper understanding concerning English teacher's difficulties in designing lesson plan based on the 2013 Curriculum. This qualitative case study employed observation, interview and document analysis. The instruments of collecting data consisted of observation checklists, an interview guide and field notes. The subject was one English teacher at SMP Negeri X Singkawang who has implemented the 2013 Curriculum. This research revealed that English teacher encountered difficulties in designing lesson plan based on 2013 curriculum on three stages. In pre design stage, the teacher found the difficulties in term of inability to formulate and design lesson plan due to limited time constraints. In whilst design stage, the English teacher experienced difficulties in assessment with many variables. In post-design stage, the English teacher coped with students’ reluctance in the teaching learning proces since the learning process was not appropriate with the lesson plan and lacked of facilities at school. It is recommended that the teacher should put more efforts to improve professional competencies by participating in activities such as training and workshop and accelerate knowledge improvement, creativity and technology to be able to apply the 2013 curriculum effectively.

Published: October 2020

Digital storytelling (DST) is one of the helpful educational tools in the teaching and learning process. Nonetheless, there is a scarcity of systematic reviews to enlighten how it was applied and what was done in this area. This paper performed a systematic review of five articles on using DST to foster English speaking skills among learners. This research established continuous interest in the background of South-East Asian countries, including learners at the pre-school till tertiary education levels. DST has been used in the humanities and social sciences as either a stand-alone teaching or in conjunction with other teaching techniques. The review classified two directions (ideal and reflective) as well as six outcomes: affective, intellectual, educational, technical, linguistics, and communal. Hence, this study synthesizes and discusses further two issues: affective motivating passion and a creative, imaginative, and resourceful platform. It is hoped this study able to discuss potential explanations for these issues and offer insights for future studies.

Authors: Akangoziri O. , Okoli C. N. 
Published: October 2020

This study examined comparison of the Multiple logistic regression, Linear discriminant analysis and Quadratic discriminant in estimating the infant birth outcome and misclassification error rate of birth outcomes with factors of infant mortality in Anambra State, Nigeria. The birth outcomes of interest were the Neonatal death, Still birth and Alive. Secondary source of data were obtained from the records department of General Hospital Onitsha from 2007-2016. The data comprises of Status of infant birth, Mothers parity, Age of mother, Weight of baby, Mothers Education Status, Number of Bookings before gestation and Gestation Age. The data analysis is performed using R-software. The result of the findings from the multiple logistic regression showed that Mothers Education Status (MES) and Booking contributed significantly on the logistic model while factors of Parity, Sex, Age of Mother (AOM), Year, GA and Birth Weight (BW) were found to be insignificant on birth outcomes. Also observed that the misclassification error rate for birth outcome for the said approach is found to be 0.5992 (59.92%). More so, findings of the study equally showed that the prior probabilities of the groups for the linear and quadratic discriminant analysis were 0.228503, 0.40168 and 0.36981 for Alive, Neonatal death and Still birth respectively. Further findings revealed that the Mothers Education Status and Bookings Status have the greatest impact for first and second linear function respectively. In addition, the result of the misclassification error rate for birth outcome using the linear discriminant analysis is 0.5931 (59.31%). The misclassification error rate for birth outcome based on quadratic discriminant analysis is 0.5956 (59.56%). Based on the findings of this study, linear discriminant approach is the best alternative in estimating misclassification error rate of infant birth outcome followed by quadratic discriminant analysis and the least is multiple logistic regression. The findings clearly confirmed that the linear discriminant analysis is the best with misclassification error rate of 59.31%.

Published: October 2020

Palm oil is one of important Indonesia's export commodities. In 2017, the export value of palm oil and its derivatives (excluding oleochemicals and biodiesel) penetrated US $ 22.97 billion. The bright prospect of the palm oil commodity in the world vegetable oil trade encouraged the Indonesian government to develop an integrated palm oil industry. On the other hand, some downstream petrochemical products have begun to experience difficulties in raw materials, including Polyurethane. Polyurethane is a polymeric material from polyols and isocyanates which are widely used as packaging. Polyol itself is a polyether produced from the petroleum fraction. The polyol industry can be developed in the industrial tree branch of glycerol / glycerin in the large palm oil industry tree. Glycerin is generally the most end product of the palm oil fractionation industry, after cooking oil, margarine, shortening, and soap. In addition, glycerin is also a by-product of fatty acid esterification during biodiesel production. The value chain analysis carried out in the palm oil industry chain shows that polyol production has added new pathways that can extend the palm oil downstream industry chain. Analysis carried out on the main chain and the combined oil palm industry chain has been successfully used to map the polyol industry value chain on the palm oil track. The extension of the palm oil industry value chain on the polyol industry pathway can unite the industry with the chain of production of the petrochemical industry, in this case polyurethane, which at least can help substitute raw materials. A more detailed analysis of the perceptions of the role of the polyol industry in two directions, namely the palm oil industry chain with the polyurethane industry shows that there is a very large intersection of interests. Almost all perceptions of the role of key value chain activities in the polyurethane industry can be covered by the role of the value chain main activities in the palm oil polyol industry. Both value chains can be said to complement and complement each other. The production of polyester polyols can be absorbed by the needs of the polyurethane industry.

Authors: Resi Aseanto 
Published: October 2020

Soil investigation has an important role before building a building. The carrying capacity of the soil obtained from the results of soil investigations is very influential on the shape and dimensions of the foundation itself. In the PT.Asahi Forge Indonesia Project, the SPT test data is out of sync with the actual piling results related to embedded pile penetration. The design plan for piles with a length of 7 m based on the N-SPT test turned out that in the field, the piles achieved a bearing capacity at a depth of 9 meters. The final project aims to analyze and compare the carrying capacity of a single pile based on static methods and N-SPT test on the Pile Driving Analyzer. The method used in this research is the study method of laboratory test results and N-SPT. Work steps include; preparation, literature study, data collection, carrying capacity analysis, and comparison of analysis results. The results of the analysis of the carrying capacity of the piles based on the static method by the (Vijayvergiya & Focht, 1974) method amounted to 549,201 kN; The (McClelland, 1974) Method of 426,292 kN; The U.S Army Corps Method is 459,545 kN and the Tomlinson (1977) Method is 474,191 kN. While the results of N-SPT were bearing piles bearing capacity with the Mayerhof (1956) method of 738,645 kN and the Schmertmann (1967) Method of 451,327 kN. Based on these results, the N-SPT test based on the Mayerhof (1956) Method of 738,645 kN was the closest to the PDA test results of 755,116 kN. The comparison of the results of the analysis between the static test, N-SPT and PDA test is 19: 24: 30. This means that the carrying capacity of the static pile and PDA test has a difference of 37% while between the N-SPT and PDA test has a difference of 20%.
