Abstract

The objective of research is to determine the effect of welding current on the hardness, tensile strength, and microstructure from GTAW welding with ER70S2. This research used ST 41 low alloy steel material containing C = 0,16 %, Si = 0,23 %, Mn = 0,69 %, S = 0,031 %, P=0,019 %, yield point 40 kg/mm2, tensile strength 52 kg/mm2, dan elongation 32 %. ST 41 steel welding is carried out with current variations of 90 A, 110 A and 130 A with GTAW welding methode. Types of variation of the notch use are ][, V and X. The specimens was subjected to hardness, tensile strength, and metallography. Based on the result of hardness test with the factor elimination method in obtaining the angle ][ notch with current 90 A, V notch with current 90 A, and X notch with current 110 A. Tensile test results of the three materials, the highest tensile strength at the X notch with current 110 A is 416,8 N/mm2. The lowest tensile strength is obtained at welds with ][ notch is 360.73 N/mm2. From result of metallograph that we get if X notch with current 110 A is more stable, than ][ notch with current 90 A and V notch with current 90 A.

Abstract

The amount of rubber seed waste in Indonesia is highly yielded as a side product from a large amount of rubber trees plantation. The rubber seed was not processed become the usefull application yet,  thus it becomes a high volume of waste in each year. An initiative should be done to turn it as a practical material. The rubber seed is potential for natural composite along with the increasing attention toward natural composite application.This work aims to produce natural fibre composite based on rubber seed and characterize it's mechanical properties. In this work, the rubber seed natural composite produced by using the hand lay-up method. Polyester resin YUCALAC BQTN-157 was used as the matrix with the addition of 1% MEKP (Methyl-Ethyl-Ketone- Peroxide) as the catalyst. Mechanical properties of the composite were examined by using a tensile and bending test. Additionally, the water absorption test was performed according to the ASTM D 570. The result showed that the tensile and bending strength decrease with increasing the filler composition, which is added in the composite. The composite, which has the filler composition of 40% was generate the highest tensile strength. In contrast, the lowest tensile strength appeared at the composite with a filler of 60%. The bending strength trend also behaves similarly with the tensile strength as the filler composition increased. Water absorption ability of composites displays the acceptable value as it shows within the range of 2.22-2.96%.

Abstract

Mesin injection molding yang dirancang pada penelitian ini dilengkapi dengan bentuk yang minimalis sehingga dapat mendukung industri kecil dalam pengolahan limbah plastik menjadi produk bernilai guna. Material yang digunakan dalam pemrosesan plastik pada umumnya ialah jenis polimer yang sulit teruraikan sehingga digunakan jenis biopolimer Poly Lactic-Acid (PLA) pada penelitian ini dimana dapat mudah terurai oleh lingkungan. Limbah bubuk kopi yang dapat mencemarkan lingkungan kemudian dilakukan inovasi dengan dicampur PLA yang diaplikasikan menjadi particulate composite. Penelitian ini bertujuan untuk dapat merancang mesin injection molding dan pengaruh temperatur injeksi mesin terhadap hasil produk particulate composite dari PLA dan limbah bubuk kopi. Penelitian ini dimulai dengan penentuan dimensi elemen injeksi yaitu pada plunger dengan diameter 3,5 cm dan panjang 12 cm. Barrel dengan diameter dalam 3,5 cm dan tebal 3 mm dan nozzle dengan diameter keluaran 5 mm. Dilakukan simulasi dengan memperoleh tegangan yang terjadi pada pelat dudukan elemen injeksi sebesar 210 N/mm2 dan faktor keamanan yang diperoleh sebesar 12. Gaya minimal yang dibutuhkan untuk menginjeksikan material yang dilelehkan ialah sebesar 10 N. Dalam penelitian ini didapatkan hasil yang terbaik pada kondisi temperatur injeksi 170 ºC dengan hasil cacat produk yang paling rendah

Abstract

In the world of work, the quality of employees is very concerned about supporting smooth work. Companies definitely choose prospective employees who have the qualities that the company expects. because of this, universities are required to develop soft skills that are balanced with hard skills. In addition to the quality of graduates, universities must also know the needs of companies and adjust to DUDI (world of work and industry). This will have an impact on graduates who will enter the world of work. The better the name of the college, the greater the opportunity for college graduates to join the company.Keywords: Quality of Graduates, Satisfaction, and Company Needs.

Abstract

Usaha pengolahan sampah sebagai upaya untuk dapat meminimalisir dampak negatif dan meningkatkan nilai kemanfaatan dari sampah terus digalakan. Kelompok tani Sumber Rejeki di Kecamatan Balikpapan Utara Kalimantan Timur fokus terhadap pertanian organik dengan mengolah sampah menjadi berbagai jenis pupuk padat dan cair. Proses pengolahan dilakukan secara manual sehingga berdampak terhadap kualitas dan kuantitas pupuk yang dihasilkan. Pelaksanaan program pengabdian masyarakat ITK terhadap mekanisasi proses pengolahan sampah organik dilakukan untuk mampu menghasilkan produk pupuk berkualitas baik dengan kapasitas mampu memenuhi kebutuhan petani. Proses mekanisasi diwujudkan dengan membuat alat pengolah pupuk organik (APPO) mampu menghaluskan bahan organik dengan kekerasan tinggi seperti ranting pohon, pelepah kelapa, hingga sabut kelapa. Alat Pengolahan Pupuk Organik telah dirancang dengan sistem rotari dilengkapi mata pisau menyudut. Pengujian terhadap unjuk kerja alat tersebut dilakukan terhadap bahan serabut kelapa dan pelepah pisang yang merupakan bahan pembuatan pupuk organik. Hasil pengujian menggunakan APPO diperoleh bahwa hasil pemotongan yang lebih halus dengan waktu yang lebih singkat, sehingga berdampak terhadap peningkatan kualitas dan kapasitas produksi pupuk kelompok tani Sumber Rejeki.

Abstract

Improving community expertise through motorbike maintenance training is carried out as a form of community service. This was done to help improve the quality of human resources (HR) in the community of Batu Ampar Region, North Balikpapan. The final target of each activity provided basic ability to compete in terms of skills and the opportunity to open new job opportunities. Human resources are the subject or object of development, covering the entire human life cycle, from conception to the end of life. Therefore, developing the quality of human resources is very important, especially in small things. Based on the cycle above, there needs to be an effort to provide alternative solutions that can improve quality, one of which is regarding vehicle maintenance knowledge. Community service activities carried out by ITK Mechanical Engineering and SAA (Student Automotive Association). The general activities carried out are divided into 3, such as basic automotive workshops, basic automotive practices, and free service. After being provided with material about motorbike maintenance, the community is equipped with motorbike maintenance practices with the hope that the community can independently open a repair shop (independent repair shop).
