Abstract

Friction Stir Welding process, which is a solid state welding tool utilizing friction with the workpiece to soften the material is spliced into a choice in aluminum welding. Selection of the proper tool will produce welds with excellent mechanical properties. The research objective is to determine the effect of different forms of pins on mechanical properties and microstructure joint of the friction stir welding process. Friction stir welding process by means of a rotating tool to penetrate into the work piece and friction will soften the material. The connection formed by the merging of soft metal on both sides with a pressure tool. The process of friction stir welding aluminum 5083 - H112 using milling machines and tool with a tapered pin grooves, a cylinder pin grooves or a triangular pin groove and using 1500 rpm tool rotation , the welding speed of 29 mm/min, 0° tool tilt angle, and the depth of plunge 4.8 mm indicate the process is going well . Mechanical testing indicates hardness value using is 85 HV and impact value is 0.24 J / mm2 using a tapered pin groove higher than the cylindrical pin groove and a triangular pin groove. The highest tensile strength used a tapered pin groove of 172 MPa is still lower than the base metal tensile strength of 331 MPa because there was defect in the weldment. Microstructure observation showed changes into a finer grain in the weld nugget compared Thermomechanically area Affected Zone, Heat Affected Zone and the parent metal. Friction  Stir Welding process aluminum 5083 - H112 using a tapered pin grooves tool provide better results than that using a cylinder pin grooves or a triangular pin groove.Keywords : solid state, FSW, milling, probe, Weld NuggetABSTRAKAluminium mempunyai sifat mampu las lebih rendah daripada baja karena adanya lapisan oksida yang terbentuk ketika teroksidasi dengan udara luar.

Abstract

ABSTRACTNutrition problem contributes to the death rate of toddler. In Aceh Province during 2013,  there are 855 toddlers suffering malnutrition and only 14,04% of them recovered, 2,46% died and there are still 714 more toddlers under treatment.Qualitative descriptive research with observational design through action research approach using  Geographical Information System (GIS) are carried out in the city of Banda Aceh where the sample of children with malnutrition are obtained from the result of nutrient status monitoring, weighing routine data in posyandu, investigation of the health facilities and the report from society. The collected dependent data variables are children with severe malnutrition and malnourished children, the residence location of the research subjects, the work place of the nutrient management employee, the community health center (puskesmas) and serving fasilities of children with severe malnutrition by Global Positioning System (GPS).The distribution pattern and regions prone to children with malnutrition are concentrated in Kecamatan Kuta Raja, Kecamatan Meuraxa and Kecamatan Ule Kareng. In those districts, the number of children with severe malnutrition is above 0,6% and the number of malnourished children is also above 1,5% of the minimum tolerance number of children set by the City Health Department of Banda Aceh. The percentage of the weighed children to the number of target (D/S) for those districts is in between 53,7% to 69,5%. The number of recovered children after being treated is 7,2%, while 0,9% are died and 9,9% of the children with severe malnutrition are dropped out.  The number and the distribution of nutrient management employee are not sufficient and they are not well trained with 21,2% of the posyandu are active. In the other hand, the number and the distribution of puskesmas and hospital are fairly equally distributed throughout Banda Aceh. The development of severe malnutrition children monitoring management information system creates the information of improvement of children with severe malnutrition, distribution map of nutritional cases, the distribution of human resources and the health facilities, and produces a report of success coverage of nutritional program indicator.The distribution pattern and regions prone to malnutrition are distributed in the coastal area and in the city border which are slum and poor region. The regions also suffer low quantity and quality of nutrient officer, limited operational infrastructure, and only few posyandu are active . The severe malnutrition children monitoring management information system can help through evaluating the improvement of the children’s recovery and it can also produce various information needed. Keywords: Spatial information system, improvement monitoring, toddler, severe malnutrition

Abstract

ABSTRACT: This research is motivated by teachers who rarely use learning models in every learning process because of the teacher's lack of understanding of learning models that can make it easier for teachers to implement the learning process in the classroom. This research is classified as a school action research, with four main steps, namely: planning the action, implementing the action, observing (observation), and reflecting, involving nine teachers as a sample at SMP Negeri 01 Muara Bungo. The results of the study can be concluded that using learning models in the teaching and learning process can increase teacher motivation and student learning. This is evident in the first cycle of all teachers (nine people) including the assessment of learning outcomes in the lesson plans of implementing their learning models even though the sub-components (techniques, instrument forms, questions), scoring guidelines, and answer keys are incomplete. If percentage, 56%. each teacher gets a score of 1 and 3 (not good and good), three people get a score of 2 (good enough), and one person gets a score of 4 (very good). In the second cycle the nine teachers included the assessment of learning outcomes in the RPP for the application of the learning models even though there were teachers who were still wrong in determining the technique and form of the assessment. Seven people got a score of 3 (good) and one person got a score of 4 (very good). If in percentage, 78%, there is an increase of 22% from cycle I.

Abstract

Pemeliharaan ternak sapi di Kota Mataram menghadapi beberapa permasalahan, antara lain: masih bersifat peternakan rakyat, belum berorientasi bisnis, dukungan terhadap penerapan iptek di bidang pakan masih rendah, dan terbatasnya permodalan. Dalam rangka membantu memecahkan berbagai masalah tersebut perlu dilakukan kegiatan “Diseminasi Teknologi Pembuatan Pakan Sapi Bali Berbasis Kulit Buah Kakao (KBK)  fermentasi di Kelompok Ternak Sapi “Bahtera Damai” Dusun Sembalun Kelurahan Tanjung Karang Kecamatan Sekarbela Kota Mataram. Tujuan program  Diseminasi  adalah untuk melatih anggota peternak dalam membuat pakan berbasis KBK fermentasi dengan menggunakan inokulum air kelapa (Inukulum non komersial), mengolah limbah kandang dengan metode biokonversi menjadi kompos dan mengoptimalkan pemanfaatan biogas sebagai salah satu sumber energi untuk penerangan serta keperluan memasak. Metode yang diterapkan adalah  metode pendekatan PRA (Participatory Research Appraisal), metode action research dan metode demonstrasi/uji coba yang dilaksanakan secara persuasive yaitu melakukan praktik  pembuatan pakan sapi Bali berbasis KBK fermentasi. Hasil kegiatan menunjukkan bahwa Pakan sapi Bali dalam bentuk KBK fermentasi dapat memberikan pertambahan bobot badan harian (PBBH) sebesar 0,568±0,246kg/ekor/hari lebih tingi dibandingkan dengan PBBH sapi Bali dengan pakan konvensional dicampur jerami jagung sebesar 0,376±0,251 kg/ekor/hari. Pertambahan bobot badan harian  yang tinggi akan diikuti dengan bertambahnya bobot potong dan pada akhirnya persentase kakrkas dan produksi daging akan meningkat.

Abstract

Drug abuse, namely drugs, is a threat to the sovereignty of the nation and the state of drug eradication requires the role of all parties to narrow the movement of drug dealers who are still trying to market these illegal goods in indonesia. The regulation on narcotics crime and death penalty is very important in regulating the law for perpetrators of narcotics crime for the benefit of the sovereignty of the nation and state.In Indonesia today, the imposition of criminal sanctions in the form of capital punishment by a judge for perpetrators of narcotics is one of the policies adopted in Law No. 35 of 2009 on narcotics and cannot be separated from the criminal law norms adopted by criminal law so far, for example in Article 10 of the Criminal Code. Another thing in other parts of the world there is a significant development of narcotics users by taking depenalization actions against users aimed at replacing prison sanctions which are sometimes applied other criminal sanctions such as Social Work sanctions. The research method used is empirical juridical meaning is to identify and conceptualize the law as a real and functional social institution in a patterned life system. Meaning is to identify and conceptualize the law as a real and functional social institution in a patterned living system.

Abstract

Marriage based on the provisions of Allah and His Messenger will make a happy household in this world and the hereafter based on sharia. The development of current trends in communication, information and technology can disrupt the noble value of marriage if it is misunderstood and misused. The real negative impact that occurs in society is the increasing number of women who become pregnant outside of marriage due to promiscuity. This study aims to examine the law of pregnant marriages in terms of three legal perspectives; Mazhab Fikih, Compilation of Islamic Law (KHI) and Maqāshid Shariā'h. This research is literature research with a literature approach. This type of research is library research with a document study approach where primary and secondary data are obtained from books, journals, books and references that discuss pregnant marriages. The results of this study found that the Ulama Mazhab Fikih discusses the act of pregnant marriage in Fikih and there is khilafiyyah related to the provisions and conditions for pre-marrying women who are pregnant outside of marriage and after marriage. The Compilation of Islamic Law (KHI) which regulates pregnant marriages in article 53 has fulfilled the five main objectives of sharia (adh-Dharūriyyah al-Khamsah); maintaining religion, soul, intellect, offspring/honor, and property after being reviewed with Maqāshid Sharī'ah.

Abstract

Abstrak Tertulis dalam Pasal 197 UU Kesehatan Nmor 36 Thn 2009: Barangsiapa dengan sengaja memproduksi ataupun menjual zat yang dikendalikan ataupun alat kesehatan tanpa izin yang sesuai, melanggar hukum, sebagaimana dimaksud dalam Pasal 106 Bagian 1, diancam dengan pidana penjara paling lama 15 Th penjara dan denda paling banyak Rp1.500.000.000,00. Meskipun demikian, kejadian peredaran gelap sediaan farmasi berupa obat tanpa izin edar terus dilaporkan di wilayah metropolitan Medan. Mengapa kami melakukan riset ini: untuk menjelaskan penyebab peredaran obat-obatan ilegal di Medan tanpa izin yang sesuai dan menguraikan langkah-langkah yang diambil untuk mengatasi kekhawatiran penegak hukum terkait peredaran obat-obatan ilegal di kota Medan . Buku, majalah, Hukum Pidana, dan UU ditinjau untuk informasi, dan wawancara dengan responden dan informan dilakukan untuk studi lapangan. Temuan riset ini menunjukkan bahwa Penegakan hukum yang tidak efektif merupakan masalah utama di Kota Medan yang bermasalah dengan peredaran obat ilegal. Faktor ekonomi dengan mencari keuntungan yang besar, kurangnya kesadaran hukum dari pelaku dan masyarakat, faktor sosial dan lingkungan sosial serta upaya yang dilakukan dalam penanggulangan kejahatan ini dengan cara sosialisasi dan memberikan pemahaman kepada warga dan pelaku yang mengedarkan sediaan farmasi, serta BPOM melakukan pemeriksaan dan pengontrolan obat. Upaya penegak hukum untuk menjatuhkan putusan berdasarkan UU yang berkaitan dengan sediaan farmasi, termasuk penahanan dan sanksi moneter, tidak berbeda dengan yang dilakukan untuk melakukan delik. Disarankan kepada pihak yang berwenang dalam menangani delik peredaran sediaan farmasi berupa obat tanpa izin edar agar dapat ditindak secara tegas dan tetap memperhatikan peraturan perUUan yang berlaku agar dapat memberikan memberikan efek jera bagi para pelakunya.Kata Kunci : Penegakan Hukum, Tindak Pidana., Sediaan Farmasi, Tanpa Izin Edar
