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: Dengue Haemorraghic Fever disease (DHF) is dangerous contagious disease which is caused by dengue virus which is brought by Aedes aegypti mosquito. Controling DHF depends on the control of the mosquito and its larvae. One of alternative larvacide that can control Aedes aegypti larvae is larvacide with active ingredient pyriproxyfen as Insecth Growth Regulator (IGR) which does not influece the hygiene of water, safety and does not increase the resistancy. The purpose of the study is to study and calculate efficacy of an IGR pyriproxyfen against Aedes aegypti larvae which was only collected from East Banjarmasin. The research is an experimental research that used seven kind dozes of IGR: follows 0,1 ppm, 0,05 ppm, 0,01 ppm, 0,008 ppm, 0,005 ppm, 0,003 ppm, and control. Each doze used four replications. The research results showed that IGR was effective to kill more than 70% larvae after seven days. The results of probit analysis were 0,001 ppm ana 0,065 ppm to kill 50% and 90% larvae. Keywords: Dengue Haemorraghic Fever, pyriproxyfen, Aedes aegypti ABSTRAK: Penyakit Demam Berdarah Dengue (DBD) adalah penyakit menular berbahaya yang disebabkan oleh virus dengue yang dibawa oleh nyamuk Aedes aegypti.

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

The purpose of this study was to determine the effect of heating on the welding process of SMAW (Shielded Metal Arc Welding) in terms of hardness and microstructure of welded metal. Much welding has been done by preheating but below the temperature used below the initial martensitic temperature which reaches 452 ° C, this data is sourced from research by S.Zheng et.al and Y. Huang et.al. For this reason, an experiment was carried out with heat temperatures above a martensitic temperature of 500 ° C. The results show that in the Weld Metal area the pearlite structure appears larger, the effect of current strength on HAZ width is directly proportional, the greater the current strength, the wider HAZ, and hardness are affected by the rough grains of martensite

Abstract

Dalam proses penggantian disc pad brake dibutuhkan alat khusus untuk menekan piston ke dalam kaliper. Untuk kaliper tipe single piston Teknisi menggunakan SST (Special Service Tool) yang sudah ada di bengkel AUTO 2000 Radio Dalam sehingga pengerjaannya lebih mudah. Sedangkan untuk kaliper tipe double piston, Teknisi menekan piston ke dalam kaliper menggunakan dua buah obeng hal ini dapat menyebabkan kerusakan pada disc rotor, disamping itu pengerjaan membutuhkan waktu yang lama, dan dapat menyebabkan terjadinya kecelakaan kerja. Menurut penulis, proses di atas kurang efektif. Untuk itu dibuatkan SST AL01 dan SOP (Standard Operating Procedure) baru demi memudahkan Teknisi dalam melakukan penggantian disc pad brake tipe double piston. Cara kerja alat ini dapat menekan kedua sisi piston rem secara bersamaan sehingga pengerjaan tersebut menjadi lebih mudah dan cepat. Alat ini dapat meningkatkan efisiensi waktu penggantian disc pad brake tipe double piston sebesar 26.31 % dan alat ini tidak hanya dapat digunakan untuk double piston melainkan untuk single piston juga.
