PENGARUH CAPITAL STRUCTURE TERHADAP PROFITABILITAS UJI MODEL KUADRATIK PADA PERUSAHAAN SEKTOR AGRIKULTUR YANG TERDAFTAR DI BEI PERIODE 2012-2016

This study aims to analyze the effect of capital stucture towards profitability using return on assets (ROA) as a proxy in agriculture sector companies listed in Indonesia Stock Exchange (BEI) in the period 2012-2016. This research uses quantitative approach with quadratic regression analysis model. This study uses sample of firms which are listed on agriculture sector in IDX on 2012- 2016. The number of final samples used in this study were 15 business entities with 75 observations. The study findings suggest that the TD variables have positive and significant effect towards profitability, while the TD2variables have negative and significant effect towards profitability in agriculture sector companies BEI on the period 2012-2016

On Hopf's Lemma and the Strong Maximum Principle

In this paper we consider Hopf's Lemma and the Strong Maximum Principle for supersolutions to a class of non elliptic equations. In particular we prove a sufficient condition for the validity of Hopf's Lemma and of the Strong Maximum Principle and we give a condition which is at once necessary for the validity of Hopf's Lemma and sufficient for the validity of the Strong Maximum Principle.Comment: 27 pages,4 figure

Magnitude and Causes of Visual Impairment and Blindness Among Children Attending Paediatric Eye Clinic at Muhimbili National Hospital, 2010

The number of blind years resulting from blindness in children is alarmingly high. Blindness in children can have a significant impact on their performance at school as well as their social interaction and future employment as visually impaired children have a long lifetime of blindness ahead of them. The consequences of visual impairment and blindness in children are an important public health issues with greater impact in developing countries, where 80% of the blindness in children occurs. The control of blindness in children is considered a high priority area within the World Health Organization’s VISION 2020 initiative. However many developing countries do not have the accurate information about the magnitude and causes of visual impairment and blindness in children, from which the scope and priorities for prevention and treatment can be identified. To date the established pediatric eye clinic which works as a tertiary eye centre does not have baseline data on the magnitude and causes of visual impairment and blindness in children. To determine the magnitude and causes of visual impairment and blindness in children attending pediatric eye clinic at Muhimbili National Hospital, Dar es salaam Tanzania 2010. A cross-sectional study was conducted between June and December 2010. A total of 232 children aged 15 years and below attending pediatric eye clinic at the Muhimbili National Hospital were enrolled. Interview and physical examination was done. The visual acuity of 201 children was assessed by quantitative methods while that of 31 children was assessed by light fixing and following Method. Among the 201 children assessed by quantitative methods 8% had visual impairment and 4.0% were blind. Of the 62 eyes evaluated by light fixating and following method, 8 (12.9%) eyes were not able to fixate and follow light. There were multiple causes of visual impairment and blindness among the affected children. Ocular trauma was the predominant cause of both uniocular visual impairment and blindness causing 15, 29.4% and 17, 34.7% respectively. Amblyopia due to congenital cataract was the leading cause of bilateral visual impairment accounting for 31.3% while cortical blindness was the main cause of bilateral blindness responsible for 50.0% of bilaterally blind children. Abnormalities of the optic nerve emerged as an important cause of visual impairment and blindness which affected 7(43.8%) visually impaired children and 2 (25.0%) blind children. Visual impairment and blindness in children is high among the children attending the pediatric eye clinic at Muhimbili National Hospital with younger children being more affected with blindness than the older ones. Corneal scaring due to measles and vitamin A deficiency were not seen as the causes of visual impairment and blindness in these children. Efforts towards prevention of ocular trauma among children and improvement of antenatal and natal care so as to reduce birth asphyxia and consequently cortical blindness should be emphasized.\u

META-ANALITIK COLLABORATIVE GOVERNANCE DALAM PEMBANGUNAN BERKELANJUTAN

Collaborative governance dianggap sebagai solusi dari capaian tujuan pembangunan berkelanjutan karena melibatkan berbagai pihak yang akan membantu prosesnya. Studi ini bertujuan untuk menganalisis tren pembahasan collaborative governance dalam pembangunan berkelanjutan di lingkup global yang terindeks dalam database Scopus dengan rentan waktu 2013-2023 menggunakan analisis bibliometrik dengan memanfaatkan software VosViewer dan Biblioshiny dalam proses pengolahan data dan visualisasi data. Hasil pencarian data menghasilkan 623 dokumen dengan artikel jurnal sejumlah 445 yang dianalisis. Publikasi mengenai collaborative governance dalam pembangunan berkelanjutan terbanyak dilakukan pada tahun 2022 dengan 91 publikasi. Sementara paling sedikit pada tahun 2014 dan 2023 dengan 19 dan 18 publikasi.  China dan United States menjadi negara yang paling produktif mempublikasi. Wageningen University & Research dan Chinese Academy of Sciences menjadi Universitas terbanyak menghasilkan publikasi. Metode bibliometrik dapat digunakan untuk menganalisis tren pembahasan collaborative governance dalam pembangunan berkelanjutan di lingkup global. Akan tetapi, perlu dukungan dataset serta sistem komputasi yang lengkap. Hasil analisis penelitian ini menunjukkan terdapat peningkatan tren publikasi.   Kata Kunci: Bibliometrik, Collaborative governance, Pembangunan Berkelanjutan.Collaborative governance dianggap sebagai solusi dari capaian tujuan pembangunan berkelanjutan karena melibatkan berbagai pihak yang akan membantu prosesnya.
