Field studies carried out in this practical work activity were by visiting directly to the production department of PT. Ciptaunggul Karya Abadi. The data used in this study were obtained from data regarding uncertainty during the tapping process if it is intended to make internal threads of different sizes that occur in the Taiwan Tapping Machines M32 semi-automatic tapping machine and also the interview method conducted directly. The data that has been obtained is then continued by designing a fishbone diagram. From the results of the study, based on the results of the analysis using the fishbone diagram method about broken pins on the tapping machine, there are 4 influencing factors, namely: material, method, machine, and human. Of these 4 factors, the biggest influence on the broken pin on the Taiwan Tapping Machines M32 type tapping machine is the manpower and method. This is because the operator has only worked for less than a month, there is no retraining and the SOP (Standard Operational Procedure) is not posted on the machine work area.</em></strong></p> Reynaldi Harliansyah, Deri Teguh Santoso Copyright (c) 2022 Reynaldi Harliansyah; Deri Teguh Santoso https://creativecommons.org/licenses/by-sa/4.0 https://ojs.unpkediri.ac.id/index.php/JMN/article/view/17905 Sat, 21 Jan 2023 00:00:00 +0700 Analisa Pengaruh Kecepatan Putaran Terhadap Visual Lasan Dengan Menggunakan Metode NDT ( Non Destructive Testing ) Pada Proses Friction Welding https://ojs.unpkediri.ac.id/index.php/JMN/article/view/17938 <p><em>In the current era, human thinking about the use of technology is increasingly widespread and growing. Currently, welding has been used in many material applications with a variety of different methods. When viewed widely, welding has been used in joining rods in metal building construction and machine construction. In detail, welding is a metallurgical bond at a metal or alloy metal joint which is carried out in a melted or liquid state in a local joint using heat energy. Various methods and developments have been carried out to obtain welding alternatives with fairly good results and are environmentally friendly, one of these methods is friction welding (friction welding) solid-state welding without the use of filler metal where the welding process occurs due to the incorporation of the wrong rotation rate. one workpiece with the compressive force exerted by the other workpiece against the rotating end of the workpiece. The purpose of this study was to determine the variation of friction welding on the visual results on steel37 by varying 3 diameters 8mm, 12mm, 16mm. This study uses an experimental method to see the visual results of the welding process. The results showed that testing using penetrant testing on specimens obtained the best results at a diameter of 16mm, having a 3mm indication of the length of the penetrant at a rotation speed of 1140 rpm with a time of 114 seconds.</em></p> Purbo Suwandono Copyright (c) 2022 Purbo Suwandono https://creativecommons.org/licenses/by-sa/4.0 https://ojs.unpkediri.ac.id/index.php/JMN/article/view/17938 Sat, 21 Jan 2023 00:00:00 +0700 Pengaplikasian Elemen Pemanas Pada Mesin Pelet Kapasitas 40 Kg/Jam https://ojs.unpkediri.ac.id/index.php/JMN/article/view/18119 <p><strong>Di Indonesia ikan lele </strong><strong>adalah salah satu</strong><strong> jenis ikan konsumsi yang </strong><strong>cukup disukai masyarakat. Ikan lele adalah salah satu pilihan budidaya ikan yang memiliki peluang besar, namun ada beberapa permasalahan yang dihadapi oleh pembudidaya. Biasanya permasalahan yang dihadapi adalah harga pakan yang tinggi dan hasil penjualan yang relatif murah. Pakan ikan lele yang harganya cukup mahal membuat para pembudidayaikan lele banyak yang gulung tikar. Karena pembudidaya belum bisa membuat mesin pakan sendiri. Dari </strong><strong>&nbsp;permasalahan tersebut, penulis mencoba menggali dan mengobservasi para pembudidaya terhadap apa saja permasalahan yang ada di pembudidaya. Dari permasalahan yang ada di pembudidaya penulis mencoba merancang mesin pembuat pelet yang bertujuan untuk mengatasi permasalahan yang ada di pembudida. Mesin pembuat pelet biasanya mengeringkan pelet hasil dari mesin dengan blower. Penulis mencoba merancang alat pengering pelet yang menggunakan elemen pemanas agar waktu yang digunakan untuk pembuatan pelet menjadi lebih efisien. Alat pengering ini menggunakan elemen pemanas plat <em>stainless steel</em> yang memiliki daya 220 V 350 W . Berdasarkan perhitungan yang ada pada rencana serta rancangan alat pengering yang menggunakan elemen pemanas ini bisa mengeringkan pelet sebesar </strong><strong>40 kg/jam.</strong></p> Alif Putra Fadhilah, Hesti Istiqlaliyah Copyright (c) 2022 Alif Putra Fadhilah; Hesti Istiqlaliyah https://creativecommons.org/licenses/by-sa/4.0 https://ojs.unpkediri.ac.id/index.php/JMN/article/view/18119 Sat, 21 Jan 2023 00:00:00 +0700 Perancangan Mesin Pembersih Pipa dari Oli Anticorit di PT. SPINDO Unit 6 https://ojs.unpkediri.ac.id/index.php/JMN/article/view/18169 <p>PT. Steel Pipe Industry of Indonesia, Tbk. (SPINDO) is one of the industries <br>engaged in the manufacture of steel pipes for various needs, ranging from furniture, <br>construction, automotive, etc. In the process of making steel pipes, there is a special <br>treatment to slow down the corrosion rate, one of which is by dipping the pipe into <br>anticorit oil. Some of the customers asked for special treatment on the galvanized iron <br>square pipe to be cleaned of anticoritic oil. The problems that occur in PT. SPINDO <br>unit 6, namely the process of cleaning pipes from anti-rust oil is still carried out by <br>wiping the pipe surface so it takes a long time, which is 30 seconds/pipe. The purpose <br>of this design is to determine the components, engine working mechanisms, and <br>designs used in pipe cleaning machines from anticorit oil. With this design, it is hoped <br>that it can become an illustration in the manufacture of anticorit oil pipes for cleaning <br>machines for the speed up process.</p> Edwin Fitkirana, Heru Arizal Copyright (c) 2022 Edwin Fitkirana, Heru Arizal https://creativecommons.org/licenses/by-sa/4.0 https://ojs.unpkediri.ac.id/index.php/JMN/article/view/18169 Sat, 21 Jan 2023 00:00:00 +0700 Analisis Kalor Bioetanol Berbahan Dasar Sabut Kelapa https://ojs.unpkediri.ac.id/index.php/JMN/article/view/19006 <h3><em>Bioethanol is an alternative fuel that can be used as a substitute for fuel.

Masalah yang timbul seiring dengan perkembangan teknologi bahan komposit polimer tersebut adalah bagaimana memanfaatkan bahan-bahan yang sumber ketersediaannya cukup banyak yang mampu diregenerasikan untuk mengantisipasi krisis bahan terutama jenis plastik polimer, dimana tersedianya sumber bahan dipengaruhi oleh sumber minyak bumi yang tidak bisa diperbaharui. Dari sinilah timbul satu ide atau gagasan, bagaimana memanfaakan serat alam sebagai bahan penunjang atau bahan pengganti komposit yang terbuat dari polimer. Serat alam yang dipilih adalah serat bagasse, karena serat ini banyak ditemukan di sekitar kita sebagai salah satu jenis limbah. Permasalahan yang diangkat dalam penelitian ini adalah, untuk mengetahui seberapa besar kekuatan tarik serat setelah mendapat proses treatment berupa proses alkali menggunakan cairan NaOH 5% dengan waktu perendaman 0, 120, dan 180 menit. Setelah proses treatment, serat kemudian diuji kekuatan tariknya. Diharapkan hasil dari penelitian ini dapat dimanfaatkan sebagai temuan atau referensi dalam rekayasa material terutama komposit, serta dapat membantu mengurangi limbah.</strong></p> Hesti Istiqlaliyah, Ah.

Kinerja proses drilling pada material Komposit KFRP bisa diukur dengan karakteristik kualitas seperti kekasaran permukaan, <em>burr height</em>, kebulatan, konsumsi daya, gaya tekan dan delaminasi. Penelitian ini bertujuan untuk mengetahui pengaruh variasi variabel bebas sudut ujung pahat dan kecepatan makan terhadap variabel respon kebulatan. Rancangan percobaan menggunakan metode full faktorial yang berupa orthogonal array L<sub>9</sub> dengan replikasi sebanyak dua kali. Variabel bebas yang divariasikan adalah sudut ujung pahat (100°, 118°, 140°) dan kecepatan makan (50 mm/menit, 115 mm/menit dan 180 mm/menit). Variabel respon yang diamati adalah kebulatan. Proses drilling dilakukan menggunakan mesin CNC Milling. Pahat yang digunakan adalah twist drill HSS Nachi diameter 10 mm. ANOVA digunakan untuk mengetahui variabel-variabel bebas yang memiliki pengaruh signifikan terhadap variabel respon yang diamati. Hasil penelitian menunjukkan bahwa sudut ujung pahat dan kecepatan makan berpengaruh signifikan terhadap respon kebulatan.</strong> <strong>Peningkatan sudut ujung pahat dan kecepatan makan akan meningkatkan penyimpangan kebulatan, sehingga agar diperoleh profil kebulatan yang baik, maka perlu menggunakan sudut ujung pahat yang kecil serta kecepatan makan yang rendah.</strong></p> Am Mufarrih, Agus Harijono, Utsman Syah Amrullah, Nanang Qosim, Zakki Fuadi Emzain Copyright (c) 2022 Am Mufarrih https://creativecommons.org/licenses/by-sa/4.0 https://ojs.unpkediri.ac.id/index.php/JMN/article/view/19472 Sat, 21 Jan 2023 00:00:00 +0700 Rancang Bangun Mesin Pengering Lantai Basah Berbasis Remote Control https://ojs.unpkediri.ac.id/index.php/JMN/article/view/17861 <p><strong><em>The drying is a process of reducing to remove a certain amount of water in a material or place contains water.
