Abstract

The use of energy increases related with the increasing of human population on earth, it is increases because human needs energy to move. Fossil energy is the energy that still become a primmadonna. The limited of energy resources in the middle of the increasing human energy needs from year to years (growth of energy consumption in 2004 amount 4.3%) Biodiesel is one of the biomassa fuel that can replacing fuel oil. Biodiesel can be produces from Jelantah oil that has a same type of biomassa. Jelantah oil can be con verted into biodiesel by using the transesterification that reacts the reacts the oil molecules with the alcohol and the catalyst to obtain methyl esters. One of the heating methods that can be used to convert oil into biodiesel is the microwave method. This microwave heating method utilizes the wave emission absorbed by the sample temperatures, so the teperatus can be higher than the surface temperature of the partition wall. There are several factors of making biodieses that can affect the heating process. The effect of the reaction time can be seen from the percent yield of biodiesel obtained. From the result of the research, the reaction time used 5, 10, 15 with the fixed temperature 55◦c, the optimum results are obtained at 15 minutes because the contact between subtances will be more higher so can reach the higher conversion. the process variable is the amount of NaOH catalyst observed in this experiment., the best conditions, the maximum yield of used wastewater biodiesel is 74.45% obtained using a mole ratio of 1: 6 wet / methanol oil at 60 ° C with a reaction time of 10 minutes and a 1.5% NaOH catalyst.

Abstract

Femoral neck fracture is an intracapsular hip fracture. Hemiarthroplasty is one of the treatment options that replaces femoral aspect of hip joint with a prosthesis, while leaving the acetabulum intact. The treatment’s goal is to return the patient to premorbid capacity. Harris Hip Score (HHS) is an assessment for the outcome of hip surgery which contains: pain, functional capacity, deformity and range of motion (ROM). The purpose of study is to determine relation of BMI and Harris Hip Score (HHS) in patients with femoral neck fracture after hemiarthroplasty. This study is analytic-observational study with cross-sectional design conducted in June-September 2014 in Orthopedic’s Polyclinic of General Hospital dr. Zainoel Abidin Banda Aceh. Respondents in this study is 26. Comparative assessment of outcome was analysed by Kruskal-Wallis test with Mann-Whitney test as Post-hoc analysis and correlative assessment was analysed by Spearman test. Comparative assessment present significant relation of BMI (p = 0,006; r=0.458) with Harris Hip Score (HHS) in patients with femoral neck fracture after hemiarthroplasty.

Abstract

Hypoxia-inducible factor-1 alpha (HIF-1α) is a transcription factor that plays a crucial role in cellular responses to hypoxia, such as in the development of intimal hyperplasia, a common complication in arteriovenous fistula (AVF) creation. While the application of umbilical cord mesenchymal stem cells (UC-MSCs) has shown promise in various regenerative medicine applications, including tissue repair and angiogenesis, the effect of UC-MSCs on HIF-1α level in the AVF has not been tested. Therefore, the aim of this study was to evaluate the effect of UC-MSCs administration on HIF-1α levels in the AVF animal model. An experimental study was conducted on 28 local male rabbits (Lepus domestica) using a post-test-only design. The rabbits were divided randomly into four groups: normal rabbit group (negative control), placebo-treated AVF rabbit group (positive control), AVF rabbits treated with in-situ UC-MSCs injection (one dose, 106 UC-MSCs/kg body weight), and AVF rabbits treated with intravenous UC-MSCs (one dose, 106 UC-MSCs/kg body weight (BW). HIF-1α level was measured using ELISA method after 28 days post- treatment. All data were analyzed using the one-way analysis of variance (ANOVA) and continued with the Duncan’s post-hoc test. The data indicated that the levels of HIF-1α were different among all four groups (p<0.001). The post-hoc analysis revealed that the HIF-1α levels in both UC-MSC treated groups were significantly lower compared to untreated AVF rabbits(p<0.05). This study suggests that UC-MSCs could be a promising therapy to prevent and reduce intimal hyperplasia in AVF.

Abstract

Purpose: of the study is to provide knowledge and comparative analysis of witness rules in the burgerlijk wetboek/civil procedural law in Indonesia and Islamic civil procedural law as well as to provide a comparison of witness arrangements in the burgerlijk wetboek/civil procedural law in Indonesia and the burgerlijk wetboek/Islamic civil procedure law. Result: Civil procedural law makes witnesses not perfect evidence. However, for the religious court in the case of divorce, the witness seems to have the same power as a letter, even thought in principle it is different. Contribution: This condition seems to make civil procedural law in the Islamic religious court the same as the law stipulated in the Quran&Hadith. Where as civil procedural law in Indonesia is the same between state and religious courts.

Abstract

Permasalahan inflasi harta bukan hanya terjadi di era sekarang ini, beberapa abad yang lalu permasalahan inflasi juga sering terjadi hal ini bisa dilihat dari pemikiran salah satu tokoh dalam Islam yaitu Imam al-Maqrizi. Tulisan ini bertujuan untuk mendeskripsikan secara detail terkait tinjauan histori tentang inflasi di dalam ekonomi Islam dan juga mendeskripsikan faktor-faktor yang mempengaruhi terjadinya inflasi di dalam Islam khususnya dalam pemikiran Imam al-Maqrizi. Penelitian ini menggunakan metode penelitian kepustakaan, karena data yang digunakan sudah siap adanya, pendekatan yang digunakan dalam penelitian ini adalah pendekatan sejarah dengan tujuan untuk mengungkapkan semua aspek inflasi yang ada dalam pemikiran Imam al-Maqrizi terkhusus dalam kitabnya Ighathah al-Ummah Bi Kashf al-Ghummah. Hasil penelitian menunjukkan bahwa permasalahan inflasi keuangan tidak hanya terjadi di zaman sekarang ini, akan tetapi juga terjadi pada zaman dahulu, karena secara histori Imam al-Maqrizi yang lahir pada abad ke 14 M telah menceritakan tentang inflasi keuangan di dalam banyak karyanya. Imam al-Marizi menyimpulkan setidaknya ada dua alasan utama kenapa terjadi inflasi keuangan, yang pertama disebabkan karena faktor alam atau dia sebut dengan faktor alamiah, di mana karena kondisi tertentu apakah bencana alam atau yang lainnya membuat suatu produk bisa menjadi langka dan membuat harganya menjadi meningkat secara drastis. Kedua karena faktor pemerintahan atau dia sebut dengan faktor dari manusia, faktor ini bisa diakibatkan karena terjadinya korupsi yang merajalela, atau kesalahan dalam pengelolaan administrasi dalam sebuah negara, dan bisa juga karena faktor pajak yang begitu tinggi, bahkan imam al-Maqrizi juga menyinggung salah faktor utama terjadinya inflasi karena meningkatnya sirkulasi keuangan dalam suatu negara yang memang sering terjadi dewasa ini di negara Indonesia
