Abstract

Potensi tanaman sayuran sangat terpenting di daerah-daerah saat ini. Terutama yang dilakukan di kota-kota yang luas dengan tanah yang luas. Permasalahan yang terjadi adalah penanaman benih sayuran dilahan yang luas, dan akan menimbukan tenaga besar, maka untuk itu di perlukan teknologi penyemai benih (seeder). Penyemaian benih sayuran yang dilakukan di Indonesia saat ini umumnya masih secara manual. Penyemaian manual dilakukan dengan meletakkan benih satu-persatu ke lubang tray semai. Tujuan dari penelitian ini adalah untuk mendapatkan mesin penyemai dengan performa yang lebih baik dan lebih memudahkan petani dan untuk dapat melakukan penyemaian. Penelitian ini mengunakan diagram alir dengan metode pengambilan data mengevaluasi performa dan penambahan alat pembuka alur. perencanaan alat pembuka alur di gambar dengan software auto cad dan alat pembuka alur terdiri dari sprocket, poros, pelindung poros, mata pisau pembuat alur. Alur yang di hasilkan memiliki kedalaman lebih kurang 20 cm dengan lebar 5 cm, alat pembuka alur ini akan di pasangkan dengan mesin penyemai benih yang telah di modifikas dengan mengilangkan sebuah poros yang meneruskan dari putaran pully ke poros roda, sehingga langsung dari poros pully ke poros roda. Mengevaluasi performa dan mendapatkan kecepatan rata sesudah dimodifikasi 3????⁄???? dari sebelumnya hanya 1,2 ????⁄????, dan alat pembuka alur memiliki daya 0,14 hp, torsi 0,67 nm. Hasil yang didapatkan alat pembuka alur dapat memudahkan pekerjaan petani dan mengurangi kerugian akibat benih yang tercecer sewaktu penyemaian manual dan meningkatkan kecepatan produksi penyemaian benih yang di lakukan oleh mesin penyemai benih

Abstract

Bahan baku serat nenas merupakan salah satu jenis kekayaan sumber daya alam yang belum dapat di manfaatkan secara optimal, sehingga perlu dilakukan penelitian pengembangan teknologi komposit serat alam dengan memanfaatkan serat daun nenas dan resin polyester. Adapun tujuan penelitin ini adalah untuk mendapatkan pengaruh variasi karbon aktif terhadap kekuatan tarik dan bending pada material komposit serat daun nenas dan matriks polyester, untuk mendapatkan struktur mikro terhadap penambahan karbon aktif pada komposit serat daun nenas dan matriks polyester. Pada penelitian ini cetakan terbuat dari kaca dengan ketebalan 8mm, panjang 150 mm, dan lebar 100 mm, metode yang digunakan pada pembuatan sampel menggunakan metode lay out dengan temperature ruangan dan susunan serat searah, dengan variasi susunan 30% serat daun nenas + 69% matriks + 1% karbon aktif, 30% serat daun nenas + 68,5% matriks + 1,5% karbon aktif, 30% serat daun nenas + 68% matriks + 2% karbon aktif, dan 100% resin polyester. Hasil dari penelitian yang telah saya lakukan di dapat kekuatan bending yang tertinggi pada penambahan karbon aktif 1% dengan nilai 33,29 N/mm2, dan pada hasil uji tarik di dapat nilai tertinggi pada penambahan karbon aktif 1% dengan nilai 16,75 N/mm2. Sedangkan pada pengujian foto makro di dapatkan diameter dan jarak yang tertinggi pada penambahan karbon aktif sebesar 1,5%. Pengaplikasian pada penelitian adalah untuk pembuatan polytank air pada rumah tangga.

Abstract

Repeated welding caused by welding defects in the weld joint will result in changes in the mechanical properties of the weld joint, especially in the Heat Affected Zone (HAZ). Significant changes will occur when welding on steel materials that have undergone special treatment during the manufacturing process, such as quenched and tempered S690Q steel. S690Q steel is a structural steel with high yield strength with quenched and tempered conditions. The research was conducted by doing repeated welding as a simulation of the repair process using the GMAW process. Macro observations as well as tensile, bending, hardness, toughness tests were carried out on cross sections of welded joints. From the results of all the tests carried out the results meet the requirements of the BS EN ISO 15614-1 standard, but the results of the hardness test can identify significant changes in mechanical properties in the HAZ, especially in the bottom or root pass and hot pass areas. The average hardness value decreased from 334.07 HV at the top (face) to 209.55 HV and 198.88 HV at the bottom (hot pass and root pass) on the left side of the HAZ. While on the right side of the HAZ, the hardness value is 337.40 HV to 254.34 HV and 208.64 HV. Keywords: HAZ, S690Q, Structural Steel, Quenched and Tempered Steel

Abstract

Natural plant extracts show excellent performance in inhibiting steel corrosion. Steel has a relatively weak resistance to corrosion when in a corrosive environment. The use of natural plant extracts as green corrosion inhibitors is able to provide good performance with high inhibition efficiency. Experimental methods such as gravimetric analysis, potentiodynamic polarization, and electrochemical impedance spectroscopy are commonly used to investigate corrosion inhibition based on corrosion activity. A comparative literature review of this work is important for the development and utilization of green inhibitors. Experimental studies still do not clearly reveal the mechanism of adsorption and inhibition of molecular inhibitors at the atomic level. For this reason, future developments are very important to study theoretically at the atomic level of the main components of natural plant extracts as corrosion inhibitors, so that it is hoped that there will be a clear and systematic understanding of the mechanism of corrosion inhibition in steel.

Abstract

With the decreasing of world oil reserves, energy savings programs have started across the entire world. Recently, Indonesia has now become one of the importing countries for crude oil. Biomass gasification sustainability, especially in Indonesia, is very guaranteed because of the abundant availability of biomass in Indonesia. The goals of this study are examine the 5 kW diesel generator performance against various load with diesel fuel and diesel fuel plus syngas (synthetic gas) from sawdust. This research was carried out at Renewable Energy Laboratorium of Engineering Faculty UNTIRTA. The author performed this research using 5,2 kW total load of halogen lamp. In this research the load used was only at 3.2 kW because of the "not optimal condition" of the diesel generator resulting in not optimal engine rotation. Diesel generator power value at low loading point was increased. Whereas, at high loading point was decreased.
