Abstract

In a three-phase system, the difference in the angle between the phases and the phase sequence of the system is very important to ensure the system functions normally and does not cause damage to the three-phase equipment connected to the system. Trigonometric formulas in multiphase systems are used to obtain the angle difference between the phases and the sequence of phases in the system. The trigonometric formula was tested in a simulation using MATLAB software, then applied to an Arduino Mega-based system. In the simulation, the data are two voltages vs. time with a certain phase angle difference, then using the trigonometric formula in the MATLAB program, the data is recovered from the phase angle difference and the direction of rotation of the two voltages. Based on the valid MATLAB simulation test results, the program algorithm is embedded in an Arduino Mega-based system equipped with 2 voltage sensors and a 2.4-inch TFT LCD. The Arduino Mega-based system has succeeded in detecting and visualizing in the form of a graph the angle difference between the phases and the direction of rotation of the three-phase system.

Palm oil mill is a palm oil and palm kernel processing industry which is a semi-finished product. The palm oil industry is currently growing rapidly in line with the demand for large quantities of CPO and Kernal and their derivatives. In its operation, it is always faced with various risks, from the field to the processing plant. These risks will cause losses to the factory, especially in the form of financial. From the results of field observations obtained 13 kinds of supply chain risks, namely damaged trucks, FFB not up to standard, damaged FFB, insufficient FFB, network error, FFB damaged in the sorting field, boiling problems, problematic polisyndrom, abnormal steem, abnormal processes. /stops, viber cyclone plugs and leaks pipe. Therefore, it is necessary to identify, measure and manage risks to reduce losses caused by supply chain risks. The method used in this study is the MAFMA (Multi Attribute Failure Mode Analysis) method. The MAFMA method is a development of the FMEA method. The results showed that the risk level value contained 4 critical risks on the part of the factory, namely FFB less with a risk level value of 0.096, FFB not according to standards with a risk level value of 0.085, network error with a risk level value of 0.083 and the process running abnormally. /stop with a risk level of 0.073. These 4 critical risks are the priority to be handled. The handling carried out is planning for the right FFB procurement, providing guidance on the harvesting process, stabilizing the network by providing copper rods and planning machine scheduling.

Abstract

This paper presents the characterization of LM6 aluminum alloy with varying copper addition. LM6 is a soft, light-weight and corrosion resistant metal. Due to these characteristics, the material was selected to be added with copper to identify improved properties. The amount of copper addition was varied from 0%wt with intervals of 3%wt for every alloying run. Vibration casting, or vibration molding, was conducted. The vibration process is said to give a better result in terms of the alloy's grain size and arrangement. Mechanical testing and microstructure analysis were performed to prove the theory. Specimens with various amounts of copper were successfully produced and tested. The LM6 alloy specimen casted without copper and with vibration casting at 20 Hz had the highest tensile strength and percentage of elongation, while the LM6 alloy specimen casted with 9%wt of copper without mechanical vibration casting had the best mechanical properties based on the overall results and criteria. The percentage of copper addition that produced the optimum properties was found to be 9%wt of copper without vibration molding (hardness 46.2HRB, 125 MPa).

Abstract

Judul: Analisa pengaruh variasi kompaksi terhadap kekerasan sponge iron hasil reduksi dari pasir besi Kabupaten Aceh Selatan Title: Analysis of the effect of compaction variations on the hardness of the reduced sponge iron from iron sand, South Aceh RegencyTelah di lakukan penelitian tentang karakteristik sponge iron dari bahan  baku pasir besi dan paduannya, yang berasal dari daerah Manggamat Simpang Dua kecamatan Kluet Tengah kabupaten Aceh Selatan. Sponge iron dibuat dalam bentuk pellet dengan pencampuran yang terdiri dari pasir besi (Fe) sebanyak 500 gr, karbon (C) sebanyak 2 gr, dan zat perekat sebanyak 1 gr. Pembuatan pellet terdiri dari lima variasi tekan yaitu 50  kg⁄cm2, 60  kg⁄cm2, 70  kg⁄cm2, 80  kg⁄cm2 dan 90 kg⁄cm2, yang direduksi dengan gas asitelin pada suhu pembakaran 1200℃ dengan waktu penahanan 45 menit. Hasil pengujian komposisi dengan menunjukkan kadar Fe setelah direduksi sebesar 59,38 %, dengan kadar karbon (C) 0,97%  yang membentuk hematit dengan fasa Fe2O3 (besi oksida). Hasil kekerasan material sponge iron tertinggi rata-rata pada 287,35 HV pada penekanan 70 kg⁄cm2 yang menunjukkan nilai tekan (kompaksi) optimum pada pellet pasir besi. Hasil penelitian menunjukkan bahwa pasir besi yang diperoleh dari daerah Aceh selatan dapat di produksi menjadi supply bahan baku produksi baja di Aceh. The properties of sponge iron produced from iron sand and its alloys from the Manggamat Simpang Dua region in South Aceh are discussed in this research. Sponge iron is produced in pellet form by combining 75 percent iron sand (Fe), 20 percent carbon (C), and 5 percent bentonite adhesive. Pellet manufacturing consists of five press variants, namely 50, 60, 70, 80, and 90 kg/cm2, which are reduced by acetylene gas at a burning temperature of 1200°C with a holding period of 45 minutes. The reduced to spongy pellets exhibited a dominating hematite (Fe2O3) phase fraction pattern of 59.8 percent and a magnetite phase (Fe3O4) of 40.2 percent, with a weight percentage of Fe of 66.57 percent and C of 2.30 percent. The greatest sponge iron material hardness results on average at 287.35 HV at a pressure of 70 kg/cm2 with a void size of 0.4 mm, showing the optimal compressive value (compaction) on iron sand pellets. It may be inferred that iron sand collected from the South Aceh region can be used as an alternate raw material in the steel manufacturing process.

Abstract

CV.X, merupakan perusahaan pembuat kandang baterai (Kandang ayam) yang berlokasi di Binjai-Sumatera Utara. Produk-produk yang dihasilkan beranekaragam dengan bahan baku utamanya adalah kawat hitam dan menggunakan proses produksi yang sangat sederhana mulai dari mengolah kawat gulung hingga menjadi produk jadi kandang baterai. Pemesanan bahan baku dilakukan sesuai prediksi peramalan produksi yang dilakukan perusahaan. Dalam berproduksi perusahaan menggunakan perkiraan yang tidak didasarkan pada suatu perhitungan matematis, untuk itu dilakukan penelitian mengenai perhitungan peramalan produksi untuk tahun 2010-2011. Peramalan merupakan suatu kegiatan memperkirakan atau memprediksikan kejadian dimasa yang akan datang tentunya dengan bantuan penyusunan rencana terlebih dahulu, dimana rencana ini dibuat berdasarkan kapasitas dan kemampuan permintaan/produksi yang telah dilakukan di perusahaan. Bagian awal dari suatu proses pengambilan keputusan adalah melakukan peramalan, baik peramalan permintaan ataupun peramalan produksi, dimana sebelum melakukan peramalan harus diketahui terlebih dahulu persoalan yang terjadi guna mendapatkan keputusan yang optimal sesuai dengan kebutuhan. Dalam penelitian ini peramalan dihitung dengan maksud mendapatkan prediksi/perkiraan produksi untuk periode yang akan datang sesuai dengan kebutuhan dan kapasitas produksi sehingga produksi dilakukan secara efektif,efisien secara optimal. Tujuan penelitian adalah meramalkan permintaan produksi periode juli 2010-Juni 2011. Metode peramalan yang digunakan adalah metode time series yaitu metode siklis dan eksponensial. Hasil penelitian menunjukkan bahwa perhitungan peramalan produksi untuk periode Juli 2010-Juni 2011 sebanyak 1224 Ton. Metode peramalan yang digunakan adalah metode siklis dimana pemilihan dilakukan atas dasar perbandingan metode yaitu metode eksponensial, hasil pengujian hipotesis menunjukkan bahwa Ftabel = F(α,V1,V2) =F(0.05,9,10) = 3.02, F hitung ≤ Ftabel sehingga metode siklis yang terpilih dengan standar kesalahan lebih kecil dari metode eksponensial.

Abstract

Dalam menjalankan suatu proses produksi, perusahaan akan selalu dihadapkan dengan masalah biaya, baik biaya langsung maupun biaya tidak langsung, salah satunya adalah biaya mesin. Untuk menghasilkan suatu produk diperlukan mesin yang mendukung terlaksananya proses produksi. Bag filter merupakan alat pengumpul debu yang sering digunakan di pabrik semen. Bag filter dapat menyaring 99% debu halus yang bercampur udara panas. Suatu mesin yang beroperasi memerlukan biaya tahunan yang meliputi biaya perawatan, biaya sumber tenaga, biaya tenaga kerja dan lain-lain. Selama biaya tahunan masih lebih kecil dari nilai produksi, maka mesin itu masih berada dalam batas umur ekonomis, tetapi bila biaya tahunan sudah melebihi nilai produksi maka mesin itu tidak lagi ekonomis dipergunakan, walaupun secara teknis masih dapat dipergunakan.Tujuan dilakukan penelitian ini adalah, menentukan umur ekonomis mesin bag filter(BF-01) dengan menggunakan metode biaya tahunan rata-rata. Hasil penelitian diperoleh bahwa total biaya tahunan rata-rata minimum adalah pada tahun pemakaian ke-8 (delapan) yaitu pada tahun 2017 sebesar Rp 5.533.375, artinya umur ekonomis mesin berada pada tahun ke-8. Maka, apabila mesin bag filter masih tetap digunakan dalam jangka waktu panjang, akan mengakibatkan biaya produksi semakin tinggi, hal ini sangat berpengaruh bagi keuntungan perusahaan.
