Abstract

Concrete has many functions, and is also an important role in maintaining building stability and strength. By using plastic fiber as a lightweight concrete mixture material, it is expected to increase the compressive strength of the lightweight concrete, and also to reduce the negative impact of waste plastic bottles. In this study also added differences in FAS for each specimen 0.5 and 0.6. With the difference in variation in each lightweight concrete specimen, it is expected to be able to know the performance of concrete from the different variations of PET and FAS. The use of PET and FAS mixtures in lightweight concrete produces the lightest Concrete at 9% PET mixture of fine aggregate weight. In full there are two results, FAS 0.5 = 11045 gr, and FAS 0.6 = 10981  gr. But for the maximum weight of test specimens it cannot be said to be structural lightweight concrete because it does not meet the minimum weight requirement of 1850 Kg / m3. The Slump test on the specimen shows that the highest Slump test is in FAS 0.6 with 9% PET mixture, with slump height reaching 135 mm or 13 cm, and 125 mm or 12.5 cm in FAS 0.5 9% PET mixture. Cylinder absorbance showed that the average maximum absorption of FAS specimens was 0.5 = 1,268% and FAS 0.6 = 1,212%. The value of the lightest concrete compressive strength is the most optimum in the variation of 3% PET specimens in FAS 0.5 and variation of 6% PET specimens in FAS 0.6. that is 25 Mpa and 19 Mpa. And for the SPSS test states that there is a significant difference in the differences in the variation of PET and FAS test objects.

Abstract

This article completes the circle of presenting the process of the constant growth of objects and systems and the topics to complete it consist of the visible matter violent disintegration and its re-creation inside the Universe. A constant process of the visible matter disintegration is presented as the end of the process, the proportions of which are gigantic, and the creation of the visible matter as the beginning of it. The disintegration of particles disturbs the balance of the Universe's wholeness; despite the enormous loss of the visible matter, the Universe is constantly growing. After having postponed it for a while, this article discusses the age of objects and the Universe as a consequence of the process of the constant matter growth. The acquired results are completely different from those, offered by the renowned experts of the time.

Abstract

This study was conducted to investigate the effect of using aggregates artificial that is clay soil as partial substitution for coarse aggregates in concrete by determine the mass of concrete and its effect on the compressive strength. The proportion of aggregate artificial in design mix is 0%, 10%, 20%, and 30% with w/c ratio 0.3 and 25 MPa in strength design. The study used cylinder sample at test age 28 and 56 days. The weight of aggregates artificial is 12.97 kg and 13.05 kg for 0% subtitution, 12.07 kg and 12.12 kg, 10% subtitution, 11.45kg and 11.58kg (20%) and 10.95 kg and 11.17 kg, 30% subtitution. The test result in 0 % used aggregates artificial obtained strength concrete is 25.67 MPa and 25.95 MPa, 23.40 MPa and 23.87 MPa (10% used aggregates artificial), 18.02 MPa and 18.49 MPa (20% used) and 15.29 MPa and 15.85 MPa (30% used aggregates artificial). The results indicated that the higher the percentage in ALWA, the less the weight of concrete. Variation in aggregates artificial percentages affected the compressive strength, but in concrete ages, it did not have effect. However, the strength of the concrete may decrease, but still can be used as a structural concrete with a lighter weight of concrete.

Abstract

An inventory of tree biodiversity was carried in Ekiti State University, Ado-Ekiti, Nigeria, which is an institution where ecological and economic roles of trees are disseminated. The study involved the use of a stratified sampling technique to carry out a survey of trees species in the University. The campus was divided into four strata - Road side (A), Car parks (B), Office area (C), Student halls/ religion area (D) - and each stratum was further sub-divided into sub-strata. All the trees within each sub-stratum were identified to species level with their scientific, local and family names and they were counted and recorded. The relative frequency, relative density and relative abundance of the identified species were determined. Similarities indices and indices of diversity were determined on the tree species sampled among the strata. The results obtained revealed that a total of 27 tree species, belonging to 17 families were sampled in the campus. The family Caesalpiniaceae has the highest number of species. Some of the identified tree species were found in multiple and dual strata while some occurred in only one stratum. A total of 838 tree individuals were obtained. The most frequently occurring species were T. grandis, G. arborea and P. longifolia with 298, 181 and 149 individuals respectively. The indices of similarities among the strata were low. However Strata A and B as well as A and C appeared to be similar in tree composition. Strategies that would improve and maintain tree composition in the University campus were proposed

Abstract

Malaria-curing trees species were identified among the urban tree species previously identified in Ijesa Region of Nigeria. 25 communities were randomly selected from the region and used for this study. In each community, four adults who have lived in the community continuously for at least 10 years were purposively selected and interviewed on the medicinal values of the urban trees in the region through the use of a semi-structured questionnaire matrix. The ethnomedicinal recipes of the identified malaria-curing tree species were documented. Results obtained revealed that respondents were conscious of the medicinal values of the urban trees. 11 out of the 34 indentified tree species were used for malaria control. The malaria-curing trees were 344 out of 2156 urban trees sampled in the region. This was considered low in view of their medicinal value thus stressed the need to encourage urban tree cultivation among the populace. The malaria plant-based medicine was prepared using simple technology that mostly involved boiling in water. Thus their preparations are attainable by everybody. The extractions of most of the identified species were mostly non-annihilative but extractions predatory and annihilative extractions occurred in four species. Sustainable strategies to improve on urban tree cultivation were proposed.

This research was conducted at the Experimental Garden of the Faculty of Agriculture, Amir Hamzah University, Medan, Medan Estate Village, Percut Sei Tuan District with a height of ± 25 meters above sea level, which was conducted from May to July 2020. This study used a factorial Randomized Block Design with two factors studied, namely the first factor was the concentration of bio fertilizer Impro Tanotec (H), which consisted of 4 levels, namely H0 (0 ml/l water), H1 (1,5 ml/l water), H2 (2,5 ml/l water), H3 (3,5 ml/l water), and the second factor is the concentration of foliar fertilizer Growmore (D) which consists of 4 levels, namely D0 (0 gr/lwater), D1 (1 gr/l water), D2 (2 gr/l water), and D3 (3 gr/l water). Parameters observed included plant height (cm), number of leaves, number of stalks, root length (cm), and fresh weight per plant. (gr). The results showed that the concentration of bio fertilizer had a very significant effect on plant height at the age of 20, 40, and 60 days after planting, the number of leaves at the age of 20, 40, and 60 days after planting, the number of stalks at the age of 40 and 60 days after planting, root length, and fresh weight per plant, but did not significantly affect the number of stalks at the age of 20 days after planting. The best bio-fertilizer concentration was obtained in the H3 treatment (3.5 ml/l water). The concentration of foliar fertilizer had a very significant effect on plant height at the age of 20, 40, and 60 days after planting, the number of leaves at the age of 20, 40, and 60 days after planting, the number of stalks at the age of 40 and 60 days after planting, and the fresh weight per plant, had a significant effect on root length, and had no significant effect on the number of stalks at the age of 20 days after planting. The best foliar fertilizer concentration was obtained in D3 treatment (3 gr/l water). The interaction between the concentration of bio fertilizer and foliar fertilizers had a significant effect on the number of leaves at the age of 40 and 60 days after planting, where the best treatment combination was obtained in the H3D3 treatment (bio fertilizer concentration 3.5 ml/l water and foliar fertilizer concentration 3 gr/l water).

Abstract

Closure of nasal defect remains a challenge for surgeons. There are several ways to do nasal reconstruction, including donor site for nasal reconstruction due to its vascularity that is superior to other areas. Methods: This is a case report of a 75-year old male patient with Squamous Cell Carcinoma on his left nostril who underwent wide excision. This action left a 4-cm defect, whilst the nasal septum remained intact. This defect closure was using V-Y advancement full thickness nasolabial flap in one step. This defect closure was using V-Y advancement full thickness nasolabial flap in one step. Results: The defect closure was performed with tum over local (nasobialis) flap from the left side of the nasal cartilage. The superiority of this flap, it is able to be performed bulking, so that closure with turn over local nasolabial flap has been a sole option in nostril reconstruction for decades, which gave very good cosmetic results. After being followed for 1 month after surgery, the flap was viable, the contour was well formed, the scar was minimal, and there was no respiratory disruption. The patient was satisfied by the results. Conclusion: Nasolabial turn over local flap can be used as an option to close a relatively wide nostril

Abstract

Little is known about traditional bone setting (TBS) practise in Aceh, Indonesia despite of its common utilisation. The aim of this study was to explore the characteristics of TBS practise in Aceh, Indonesia. Thirty-nine participants from ten regencies in Aceh were interviewed from January to December 2019. Most of the participants were male (82.1%), and aged between 31-50 years old (79,5%). Half of the participants were elementary school graduates (51,3%). More than half (59%) of participants had been practicing bone setting for 5-10 years, and many of them (48.7%) used traditional massages combined with splints and herbal mixtures. None (0%) of the participant obtained legal permission to practice bone setting. More than half (71.8%) obtained the knowledge of TBS from their ancestral heritage, only one participant obtained it through apprenticeships. We concluded that TBS practices in Aceh were unregistered, and the practitioners were mostly untrained. There is a need to provide training and permits for TBS practise to ensure patients’ safety.

Abstract

Dengue Hemorrhagic Fever (DHF) patients in Indonesia reached 129,650 cases with a death toll of 1,071 people in 2015. DHF puts an economic burden on the community and government. This study aims to determine the difference in real cost tariffs and INA CBG's for DHF in a hospital in Sidoarjo, East Java. This cross-sectional study applied a descriptive design, conducted from January to December 2019. The data in this study consisted of characteristic data and differences in real hospital tariffs and INA CBG tariffs for DHF in the hospital treatment room. 625 hospitalized cases were included in this study. This hospital underwent a deficit (loss) of 30% from the difference between the total INA CBG's package tariffs and the total real hospital tariffs in 2019. There is a negative difference between the real hospital tariffs and the tariffs according to INA CBG's in the treatment of dengue fever in a hospital in Sidoarjo which produces losses for the hospital.

Abstract

Premature babies are a serious problem worldwide, with 15 million births annually and more than one million dying from premature complications. Respiratory distress syndrome (RDS) is the most common cause of morbidity and mortality in neonates (44%), almost >70% require a breathing apparatus. Nasal Continuous positive airway pressure (NCPAP) is the recommended breathing apparatus for the management of RDS, but not all of them are successfully treated with NCPAP. This study aims to determine the factors that influence the success of using NCPAP in infants aged 28-34 weeks with RDS. This study is an analytical observational study with a prospective design in infants born at Hasan Sadikin Hospital Bandung in August to November 2018 with a gestational age of 28-34 weeks and experiencing RDS. Subjects who met the inclusion and exclusion criteria had NCPAP installed and evaluated. A total of 83 research subjects found the NCPAP success rate was 45.8%. Respiratory distress syndrome was more common in male infants 57.8%. Maximum baby weight 1500 grams53(63.9%), mean gestational age 32 weeks. Gestational age, antenatal steroid administration and grade of RDS based on chest X-ray were factors that significantly influenced the success of using NCPAP (p<0.05). After controlling for gestational age, administration of antenatal steroids and the degree of RDS, there was a significant relationship between the success of NCPAP and the administration of antenatal steroids ORadj 4.67 (p=0.043) and the degree of RDS with the success of NCPAP ORadj 21.25 (p=0.001). The degree of RDS based on chest X-ray and antenatal steroid administration were factors that significantly affected the success of NCPAP.
