Authors: Allien Vipin , Kumar Hemantha , Desai Vijay 
Published: February 2020

Abstract
This paper describes the optimal selection of chopped strand mat glass-fiber-reinforced unsaturated polyester resin (CGRP) polymer matrix composite (PMC) by considering the strength and stiffness of various composite samples. The two-, four-, six-, eight- and ten-layered CGRP-PMC samples were prepared by using a hand-layup method. Then, the natural frequency and damping ratio of the CGRP-PMC samples were determined through experimental free vibration analysis using DEWESoft software. The density, tensile strength, flexural strength, impact strength, absorbed energy, inter-laminar shear strength, and fracture toughness results of the CGRP-PMC samples were considered as attributes for the selection of the optimal composite using multi-attribute decision making (MADM) techniques. The six-layered CGRP-PMC material was selected as the optimal PMC based on the results of MADM techniques.

Published: February 2020

Abstract
This study investigated the in-situ formation of TiC–Al2O3 and TiB2–TiC–Al2O3 composite coatings on the surface of austenitic 304 stainless steel by the use of 3TiO2-4Al-3C and 3TiO2-4Al-B4C powder and argon arc cladding technology. The effects of pulse frequency 0–200 Hz on microstructure and mechanical properties of coating are studied. Microstructural study of coatings showed that the high cladding temperature triggered the self-propagating high-temperature synthesis of reinforcement phases TiC, Al2O3, and TiB2 at the surface of 304 stainless steel. The use of pulsed current instead of direct current reduced the hardness of the coating by increasing the dilution. Also, in both groups of coatings, no significant difference was found between the hardness distribution over the coating layer in the specimens coated with pulsed currents at frequencies of 10 and 200 Hz.
Burn-through of a Novel Coal Gasification Burner

Abstract
A novel tip of a fuel gasification burner, designed-to-SLM (Selective Laser Melting) and made by SLM, was introduced by the client. This component failed prematurely by cracking at the cooled tip. The metallurgical cause of the failure was overheating due to blocked cooling passages, probably as a result of contaminated cooling water, leading to corrosion in the non-stainless piping systems upstream of the burner. Corrosion products, mainly iron oxides, spalled off said non-stainless components, causing blockages in the intricate cooling cavities of the AM-built burner tip. This lead to excessive thermal overload, reaching the melting temperature of the alloy at the burner tip. As a result, the subject burner tip failed by TMF cracking. Neither manufacturing nor design flaws were identified in the course of this failure investigation. It is speculated that the subject component will perform well if cooled properly. The root cause of the failure is the operation of the cooling water system of the subject burner that allowed loose corrosion products to form and to enter the burner tip.
PENERAPAN ASAS PERSONALITAS KEISLAMAN DI PENGADILAN AGAMA PONTIANAK DALAM PERKARA PERKAWINAN BAGI PASANGAN YANG BERALIH AGAMA
Authors: Rahmawati Etika 
Published: February 2020

Asas Personalitas Keislaman adalah asas utama yang melekat pada Undang-Undang Peradilan Agama yang memberikan makna bahwa pihak yang tunduk dan dapat ditundukkan kepada kekuasaan di lingkungan Peradilan Agama adalah hanya mereka yang beragama Islam. Dapat dikatakan bahwa Keislaman seseoranglah yang menjadi dasar kewenangan Peradilan Agama dan dengan kata lain, seorang penganut agama non-Islam tidak tunduk dan tidak dapat dipaksakan tunduk kepada kekuasaan Peradilan Agama. pemberlakuan Asas ini selalu dikaitkan dengan perkara perdata (bidang tertentu), seperti bidang perkara yang berkaitan dengan hal Perkawinan, baik dalam hal perceraian, pembatalan dan sebagainya. Dalam studi kasus Putusan MA No. 726K/SIP/1976 terdapat suatu pelanggaran asas personalitas keislaman dalam perkara pembatalan perkawinan yang mengakibatkan adanya perbedaan sudut pandang antar dua lembaga peradilan yaitu Pengadilan Agama dan Pengadilan Negeri. Berdasarkan putusan tersebut perlu ditelusuri lebih lanjut mengenai penerapan asas personalitas keislaman di lingkungan Pengadilan Agama Pontianak khususnya yang berkaitan dengan perkara perkawinan bagi pasangan yang beralih agama. Metode yang digunakan dalam penulisan ini adalah pendekatan yuridis normatif (Doctrinal Research) dengan spesifikasi penelitian yang bersifat deskriptif analitis. Tujuan dari penulisan ini agar masyarakat dapat mengetahui tentang asas personalitas keislaman dengan melihat latar belakang asas personalitas keislaman dalam aspek Hukum Islam dan keberadaan beberapa teori sebelum pemberlakuan asas personalitas keislaman ini, seperti teori Receptio In Complexu yang memiliki keterkaitan dan saling berhubungan dengan asas personalitas Keislaman, sehingga dapat dilihat penerapan asas personalitas keislaman yang ada di lingkungan Pengadilan Agama Pontianak telah diterapkan sesuai dengan ketentuan Peraturan Perundang-Undangan di Indonesia atau masih ada pelanggaran yang terjadi pada asas personalitas keislaman di Indonesia.

Pendingin ruang yang menggunakan sistem kompresi uap dengan menggunakan alat penukar kalor sehingga terjadi perubahan panas dan tekanan yang berada pada tekanan rendah dan tekanan tinggi yang stabil, dalam sistem ini menggunakan bahan pendingin (refrigerant) yang bersirkulasi menyerap panas dan melepas panas, serta terjadi perubahan dari tekanan rendah ke tekanan tinggi. Sirkulasi tersebut berulang secara terus-menerus dan jumlah refrigerant yang digunakan tetap dan hanya bentuk dari refrigerant saja yang berubah. Subjek penelitian ini adalah mesin pendingin jenis splite dengan kapasitas 1 PK yang banyak di gunakan di gedung kecil atau ruangan. Sedangkan untuk objek penelitian ini terdapat pada system pendingin air conditioner (AC) yang mempunyai karakteristik yang unik, panas dari engine serta kondisi-kondisi lainnya yang mempengaruhi design dan masalah pada sistem air conditioner (AC). Dari hasil penelitian dapat disimpulkan bahwa semakin tinggi putaran kompresor maka COP akan menurun, meningkatnya putaran kompresor menyebabkan temperature dan tekanan refrigerant yang keluar kompresor akan semakin meningkat, sehingga kerja kompresi yang dilakukan juga semakin besar. Hal ini berkebalikan dengan temperatur dan tekanan refrigerant yang masuk ke evaporator. Temperature dan tekanan refrigerant yang masuk evaporator akan semakin rendah dengan meningkat putaran kompresor, hal ini menyebabkan efek refrigrasi yang dihasilkan semakin rendah.Kata Kunci : Pengkondisian udara, kompresor, evaporator

Investigation of the influence of the flow structure on the accuracy of flow measurement before a hydrometric structure in an open channel
Authors: Kusher Anatoly 
Published: February 2020

The reliability of water flow measurement in irrigational canals depends on the measurement method and design features of the flow-measuring structure and the upstream flow velocity profile. The flow velocity profile is a function of the channel geometry and wall roughness. The article presents the study results of the influence of the upstream flow velocity profile on the discharge measurement accuracy. For this, the physical and numerical modeling of two structures was carried out: a critical depth flume and a hydrometric overfall in a rectangular channel. According to the data of numerical simulation of the critical depth flume with a uniform and parabolic (1/7) velocity profile in the upstream channel, the values of water discharge differ very little from the experimental values in the laboratory model with a similar geometry (δ < 2 %). In contrast to
the critical depth flume, a change in the velocity profile only due to an increase in the height of the bottom roughness by 3 mm causes a decrease of the overfall discharge coefficient by 4…5 %. According to the results of the numerical and physical modeling, it was found that an increase of backwater by hydrometric structure reduces the influence of the upstream flow velocity profile and increases the reliability of water flow measurements.
