Strength and water absorption rate of concrete made from palm oil fuel ash

Concrete is one of the most important materials for construction industry. The material in the mixture of concrete includes cement, sand and coarse aggregate. Production of cement causes the air pollution from the emission of carbon dioxide to the air. This research studies the replacement of cement with palm oil fuel ash (POFA) in the concrete mixture. The objective of this research is to investigate the compressive strength of concrete and water absorption rate of concrete made from POFA and to compare the strength and absorption rate between conventional concrete and concrete made from POFA. This is to indicate whether the compressive strength and absorption rate are equivalent to the strength of conventional concrete. The methodology used in this research is experimental method and the palm oil fuel ash was taken from palm oil mill in Cha’ah, Johor, Malaysia. The results of this research are the specimens which contain 20% POFA has a compressive strength and water absorption rate comparable to conventional concrete

Kedudukan Hukum Badan Usaha Milik Desa Sebagai Pendiri Dan Pemegang Saham Unit Usaha Berbentuk Perseroan Terbatas

Pasal 7 Ayat (1) dan Pasal 8 Peraturan Menteri Desa PDTT No. 4 Tahun 2015 tentang Pendirian Pengurusan dan Pengelolaan dan Pembubaan BUM Desa menjelaskan bahwa BUM Desa dapat mendirikan unit-unit usaha yang berbentuk badan hukum. Namun Pasal 7 Ayat (1) Undang-Undang No. 40 Tahun 2007 tentang Perseroan Terbatas menyebutkan bahwa yang dapat menjadi subjek pendiri ialah perseorangan dan badan hukum sedangkan faktanya BUM Desa dalam peraturan perundang-undangan terkait tidak ada norma yang menyebutkan bahwa BUM Desa merupakan suatu badan hukum. Sehingga oleh karena itu menimbulkan kekaburan norma pada Pasal 7 Ayat (1) Peraturan Menteri Desa PDTT No. 4 Tahun 2015. Penelitian ini bertujuan untuk menganalisis (1) kedudukan hukum BUM Desa sebagai subjek dalam persyaratan sebagai pendiri dan pemegang saham atas unit usahanya yang berbentuk Perseroan Terbatas ? (2) akibat hukum dari unit usaha yang berbentuk Perseroan Terbatas yang didirikan apabila BUM Desa yang terlibat sebagai subjek pendiri dan pemegang saham membubarkan diri. Penelitian ini menggunakan metode penelitian hukum normatif. Penelitian ini menggunakan statue approach dan conceptual approach. Dalam menyelesaikan isu hukum peneliti menggunakan metode interpretasi hukum. Hasil penelitian menyatakan bahwa BUM Desa merupakan suatu badan usaha yang berbadan hukum karena didirikan dengan konsep badan hukum. BUM Desa merupakan suatu badan usaha berbadan hukum yang didirikan oleh Pemerintahan Desa sehingga memiliki kedudukan hukum menjadi subjek hukum dalam pendirian dan pemegang saham unit usaha berbadan hukum karena Peraturan Menteri Desa PDTT No. 4 Tahun 2015 secara tidak langsung juga menganggap BUM Desa mampu untuk melakukan perbuatan hukum tersebut. Akibat hukum dari unit usaha berbentuk Perseroan Terbatas apabila BUM Desa membubarkan diri ialah terjadinya perubahan pemegang saham karena dengan pembubaran BUM Desa maka peneliti berpendapat bahwa BUM Desa juga mengundurkan diri sebagai pemegang saham.  Kata Kunci: BUM Desa, Badan Hukum, Perseroan Terbatas, DesaAbstract Article 7 Paragraph (1) and Article 8 of Permendesa PDTT No. 4 of 2015 on the Management and Distribution of the BUM Desa explained that BUM Desa was able to establish business units in the form of legal bodies. However Article 7 Paragraph (1) of Law No. 40 of 2007 on Limited Liability Company states that the sole subject matter of the constituents are individuals and legal entities whereas in fact BUM Desa in the relevant legislation does not have a norm that states that BUM Desa is a legal entity. It therefore raises the ambiguity of the norm in Article 7 Paragraph (1) of the PDTT Proposal No. 4th of 2015. This study aims to analyze (1) the legal status of BUM Desa as a subject in the requirements as a founder and shareholder of its business unit in the form of a Limited Liability Company? (2) the legal consequences of a business unit in the form of a Limited Liability Company established if the BUM Desa involved as the founder and shareholder subject to dissolve. This research uses normative legal research methods. This study uses a statue approach and conceptual approach. In solving legal issues, researchers use the method of legal interpretation. The results of the study stated that BUM Desa is a legal entity because it was established with the concept of a legal entity. BUM Desa is a legal entity that was established by the Village Government so that it has a legal position to become a legal subject in the establishment and shareholders of a legal entity business unit because PDTT Permendesa No. 4 of 2015 also indirectly considers BUM Desa to be able to carry out these legal actions. The legal consequence of the business unit if BUM Desa dissolves itself is a change in shareholders because by the dissolution of BUM Desa, the researchers are of the opinion that BUM Desa is also resigned as shareholder.   Keywords: BUM Desa, Legal Entity, Limited Liability Company, Village

Exports and Economic Growth Nexus: The Case of Pakistan

This paper re-investigates the exports and economic growth nexus for Pakistan. The paper employs cointegration and multivariate Granger Causality Test [Toda and Yamamoto (1995)] to study the long-run and short-run dynamics among exports, imports, and real output growth over the 1960–2003 period. Results strongly support a long-run relationship among imports, exports, and output growth. Feedback effect between import and output growth and unidirectional causality from export to output growth was found. Nevertheless, the results do not confirm any significant causality between imports and exports.Exports, Economic Growth, Pakistan

Komunikasi Orang Tua Dan Pembentukan Kepribadian Anak

Education is, essentially, a lifetime experience. Education begins as early as childhood, and family become an early place to start. Parent's communication plays important role in education, especially in shaping children's personality. The roles of parents their children education aren't only limited on providing material resources needed to pay education cost. Parents also have to add and keep updating their knowledge continuously. The other key to strengthening education is by providing a healthy, harmonious, and safe environment for their children growth. This should be parents' role, too, in shaping their children's personality

Parkinson disease gait classification based on machine learning approach / Hany Hazfiza Manap

The aim of this thesis is to develop a Parkinson gait recognition technique that is able to evaluate and distinguish gait deviations experienced by Parkinson Disease (PD) patients from normal pattern. The research can be divided into two phase namely gait analysis of PD as compared to normal subjects, followed by gait classification using machine learning approach. Firstly, two types of statistical test are conducted which are independent t-test and Pearson’s correlation test. Raw gait database which consist of four basic gait features, five kinetic gait features and also twelve kinematic gait features are acquired from prior walking experiments of both PD and normal subjects. Based on statistical analysis conducted, significant different between PD and normal gait pattern are observed for four features, which are the step length and walking speed from basic features, maximum extension of hip from kinematic feature and maximum horizontal push-off force from kinetic feature. Hence these significant features are appropriate to be utilized for recognition of PD gait. Next, Principal Component Analysis (PCA) is used as feature extraction for each gait features from basic, kinetic and kinematic parameter followed by normalization based on intragroup as well as inter-group. To evaluate the effectiveness of each gait features category, Artificial Neural Network (ANN), Support Vector Machine (SVM) and Naive Bayes classifier (NBC) are chosen as classifier. Results obtained demonstrated that for ANN classifier, fusion of basic and kinematic gait features due to intra-group normalization attained performance with 100% of accuracy outperformed others. As for SVM with polynomial kernel function, the finest performance specifically 100% accuracy is attained based on basic gait features from intra-group normalization whilst NBC achieved the best accuracy of 93.75% due to fusion of kinetic and kinematic gait features with intra-group normalization. Overall, the results obtained proven the ability of the machine classifiers in classifying gait pattern of PD from normal gait pattern with basic spatiotemporal seems to be the most reliable feature for this purpose due to its superb performance that achieved during classification by the three classifiers
