Abstract

Airfoil is an aerodynamic form intended to produce a lift force with the smallest drag force. When an airfoil is passed through a fluid flow that causes interaction between the air flow and the surface, variations in velocity and pressure will occur along the top and bottom surfaces of the airfoil, as well as the front and back of the airfoil. The difference in pressure between the upper and lower surface of the airfoil is what causes the resultant force in the direction perpendicular to the direction of fluid flow, this force is called the lift force (lift). In this experiment NACA 0012 airfoil experiments have been carried out using simple wind tunnel. Experiments were conducted with the aim to determine the effect of the angle of attack on the performance of the NACA 0012 airfoil which then analyzed the lift force of the NACA 0012 airfoil. The variation of the angle of attack used was 0 °, 3 °, 6 °, 9 °, 12 °, and 15 ° and used wind speed of 21.5 m / s. The greatest lift force is obtained at an angle of attack of 9 ° with a value of 0.981 while the largest lifting coefficient with a value of 0.106. The greater the angle of attack the greater the airfoil lift force, but for symmetrical airfoil stall at an angle that is too large

Abstract

Credit markets are not always balanced because of unbalanced information and other causes. There are two credit channels that influence the transmission of monetary policy from finance to the real sector, namely bank credit channels that are more concerned with the behavior of banks that are more selective in credit selection because of asymmetric information.This study aims to determine the effect of credit that consists of investment credit, working capital credit and consumption credit to the inflation rate through Gross Domestic Product (GDP) in Indonesia. The overall data used in this study is secondary data from the result of systematic recording in the form of time series from 2007 to 2016 obtained from the Central Bureau of Statistics, Bank Indonesia Report and Indonesian Banking Statistics. Data were analyzed by using multiple regression with Ordinary Least Square (OLS) approach. Based on the results of the research, simultaneous credit has a positive and significant effect on inflation through GDP and partially found that investment credit and working capital credit have positive and significant effect to inflation through GDP, while consumption credit has positive and insignificant effect.

Abstract

Allah SWT memberikan legalitas kepada umat manusia untuk memahami makna dan isi kandungan AI-Quran , yang dikenal dengan kajian tafsir. Salah seorang mufassir yang menaruh perhatian dan memiliki kualifikasi terhadap hal itu adalah ai-Aiusi dengan karya momentalnya Tafsir Ruh al• Ma'ani. Sebagai sebuah karya dibidang tafsir, dalam penafsirannya al-Alusi menggunakan metode tahlil, yaitu menjelaskan tentang arti dan maksud ayat ayat al-Qur'an dari sekian banyak seginya dengan menjelaskan ayat-ayat demi ayat sesuai urutannya di dalam mushaf, munasabah serta kandungan ayat-ayat tersebut sesuai dengan keahlian dan kecenderungan ai•Aiusi. Di samping itu, al-Alusi juga menggunakan metodemuqqarin, karena al-Alusi mengkombinasikan antara metode ar-ra'yu dengan al-matsur. Artinya beliau menyebutkan beberapa ayat atau al- hadis,kemudian melihat beberapa tafsir dari penafsiran para mufassir terhadap ayat tersebut baik dari ulama salaf maupun khalaf, baik jenis tafsir manqul maupun ijtihad, kemudian berusaha untuk menarik kesimpulan yang lebih tepat dan menghindarkan yang dianggap kurang tepat. Sedangkan dalampenjelasannya ,al-Alusi memasukkan perspekitif sufistik sebagai upaya untuk menguak makna batin (esoteris), karena itu corak penafsirannya cendrung kepada Tafsir (aliran) lsyari/Sufi

Abstract

Insects are part of the forest ecosystem that plays an important role in the sustainability of the ecological functions of the forest plantations. The purpose of this study was to analyze the effect of thinning on insect communities and determine the types of insects which has potential to be bioindicators in order to assess the success of thinning in forest plantations. This research was conducted on forest plantation at the part of Forest Management Unit (BKPH) Cikawung and West Gede, Forest Management Resort (RPH) Ciguha, Forest Management Unit (KPH) Sukabumi Perum Perhutani Regional Division III West Java and Banten. The plot used in this research is a circular plot with a radius of 17.95 m. The traps used are malaise traps that is spread on thinning blocks at thinning intensity of 20%. The type of stand of thinning plots is Pinus merkusii in the age class 3. The obtained insects later identified to the morphospecies level. The results of the study show that thinning affect changes in environmental conditions and insect composition. In thinning blocks, there was decrease in the number of insect compositions by 11 families, 4 genera and also decrease of 3 morphospecies. Overall, thinning activities have no effect on changes over species richness index and evenness index of insect species. Diptera is a type of insect that can be used as a bioindicator, it states based on the consideration of ease in obtaining information related to taxonomy and biological properties, ease of identification, role of the ecosystem, pressure status and abundance parameters. Keywords: bioindicator, ecological assessment, forest disturbance

Abstract

Kitab suci Al-Qur’an memuat seluruh aspek kehidupan manusia termasuk politik. Oleh karena itu, kegiatan politik yang seharusnya adalah sejalan dengna syari’ah Allah SWT seperti yang telah ditetapkan dalam kitab pedoman hidup seluruh umat manusia itu. Namun pada kenyataannya keberlangsungan mekanisme politik saat ini telah menjauh dari nilai-nilai yang sudah tertulis dalam al-Qur’an dan yang telah pernah teraplikasi dalam suatu komunitas digjaya peradaban akhlak Islam masa lalu yaitu komunitas Madinah yang dibangun oleh Rasulullah SAW. Untuk itu, pada saat ini diperlukan kajian reflektif dan tafsiran kontekstual kontemporer terhadap ayat-ayat yang mengatur perpolitikan dalam Islam.

Abstract

Yogyakarta as one of the regions in Indonesia that have been given special rights by the central government so that the form of government is different from other regions. Not only in the field of government, but in other aspects to the regional spatial planning. This research wants to give an overview of the special spatial planning in Yogyakarta as stipulated in the regional regulation. For the method used in analyzing the results of this study using descriptive quantitative research methods. The findings in this study are about Yogyakarta City Privileges which is one of the strategic spaces owned by the Duchy Land Space Unit and Duchy Land Space Unit. In managing the spatial plan mentioned above in Perda No. 2 of 2010 which was then enacted, the enactment of this Act is expected to assist the rights of the community and, in fact, is still not going well. Various factors that make this still happen exist because of development that is not following applicable laws. Development malls and hotels are irregular. Like the Sleman city mall, the construction was done before the regulation took effect. Keywords: Local Regulation, Spatial Planning, Privileges

Abstract

This study aims to determine the effect of leadership style and organizational climate on the performance of lecturers at Batanghari University, Jambi. This study uses a quantitative approach with the form of correlational research which explains the relationship of each independent variable with the dependent variable, either individually or collectively, and makes predictions for the dependent variable on each independent variable. With the regression equation Y = 3,120 + 0.453 X1 + 0.494 X2 + 0.010 X3 From the above equation, it can be seen that if the leadership style can be more effective by one unit, the lecturer performance will increase by 0.453; Likewise with the organizational climate, if the organizational climate is better by one unit, the lecturer's performance will increase by 0.494, something that is not much different from motivation, namely if the motivation is increased by one unit, the performance will increase by 0.010. This means that leadership style, organizational climate and motivation have a positive correlation with lecturer performance. Therefore, it is expected that these three components (X1, X2 and X3) can be optimally improved. The results of simultaneous hypothesis testing show that the value of F count is 33.110 at the level of freedom of 95 and α = 5% greater than F table 2.02439. or sig F 0.000 <0.05, this means that simultaneously or collectively, leadership style, organizational climate and motivation have a significant effect on lecturer performance at the University of Batanghari Jambi.
