Sesuai dengan standard ISO 45001 bahwa karyawan harus berpartisipasi dalam melakukan pencegahan kecelakaan. Untuk itu perusahaan telah menetapkan Program Hazob (Hazard Observation) untuk mengidentifikasi bahaya dan melakukan tindakan koreksinya. Penerapan Program Hazob masih dengan metode konvensional, mengisi lembar form, sehingga tidak efektif, efisien dan tidak berintegrasi dengan sistem lain. Transformasi digitalisasi diperlukan dengan merubah bisnis proses pelaporan dari konvensional ke aplikasi website atau mobile Apps. Hasil dari penelitian ini terjadi peningkatan kinerja operasional keselamatan kerja dengan program Hazob (i) pengisian form secara manual bertransformasi ke system digitalisasi aplikasi website dan mobile Apps; (ii) leading indikator pelaporan hazob meningkat menjadi 1.364 dari seluruh lokasi. Ini bermakna, bahwa perusahaan telah mengidentifikasi bahaya sejumlah tersebut dalam kuran waktu 3 bulan, dan melakukan tindakan koreksi sebelum terjadi kecelakakan. Data persentasi kontribusi menunjukan bahwa semua pihak bagian di perusahaan berkontribusi untuk melakukan pelaporan hazob. Hal ini menunjukan komitmen semua tingkatan untuk melakukan pecegahan kecelakaan. Angka terbesar pada tingkatan karywan ( 63 %) berkontribusi ; (iii) dampak implementasi berupa tingkat penurunan angka kecelakaan dengan Lagging Indikator sebagai berikut : LTIR = 0 (Nol), TRIR, yang sebelumnya 0.87 di bulan juni, turun menjadi 0 (nol) dari bulan Juli sampai September 2020, dan IFT, turun terus setiap bulan dan di bulan September di angka 12.33.

Abstract

The purpose of this research is to simulate the coal distribution process using a conveyor and water regulation in the boiler whose program is made using PLC-based CX-Programmer software. The first method used in the conveyor work process is to install several lights and 2 motors on each conveyor as many as 5 conveyors are connected with a timing belt as an indicator that the conveyor is working. The second method used in the simulation of water regulation in the boiler is almost the same as the conveyor system, namely by installing several motors and lights as indicators of the boiler working, as well as adding a high/medium/low sensor to adjust the water level. The conveyor and boiler systems work automatically using PLC devices that have been programmed through the CX-Programmer. In the 3-phase (reverse-forward) motor load test, the following data were obtained: PLC input voltage is 224 Volts, V line voltage is 396 Volts, motor input voltage is 398 Volts, and motor current is 1,6 Ampere. The result of this research are used as additional measurable equipment in the energy conversion laboratory which previously amounted to 2 test equipment into 3 test equipment.

Abstract

ABSTRACT Yogyakarta metal SMEs are required to continue to innovate and develop technology to be able to adapt to market demands. Metal IKM is under the auspices of the Yogyakarta Metal Technical Implementation Unit (UPT). Metal UPT is responsible for carrying out research and studies on metal quality as well as studies on the development of metal product design technology. A large number of products from abroad makes metal SMEs must be able to compete in the market. Metal SMEs must be able to provide superiority to their products, one of the advantages that is built is presenting cookware designs, especially frypan works so that they have a competitive advantage. This study aims to determine the attributes and technical responses of the Wok Frypan-type handle product and to create a product prototype. Product technical attributes and responses were searched using the QFD method based on consumer desires. To overcome the problem of contradictions in QFD, the TRIZ method is used. The research resulted in a prototype design based on 11 attributes and 12 technical responses to the wok frypan-type Handel product. Keywords: Handle, QFD, TRIZ, Wok frypan.

Abstract

AbstactPT Petrokimia Gresik is a fertilizer manufacturer assigned by the Government to produce and distribute subsidized and non-subsidized fertilizers. The NPK 3 unit is the place where production be held. However, within March - June 2019 there was significant amount of decreasing fertilizer production caused by Rotary equipment malfunction. This occurrence caused unscheduled shutdown. PT Petrokimia Gresik experienced loss in many breakdown units. The objection of this study is to determine the factors causing the breakdown of 18C3101-2 blower engine in NPK 3 unit and to create the most effective solution to be applied while overcoming the 18C3101-2 blower engine breakdown in the NPK 3 unit. Problem of this study is what caused a breakdown of the 18C3101-2 blower engine in the NPK unit. This research applies the Root Cause Analysis (RCA) method. The result shows that using the Fishbone Diagram approach figuring out the main problem caused troubleshooting of 18C3101-2 blower engine due to a clogged spray nozzle, the main cause of a clogged spray nozzle was the initial setting of spray nozzle pipe installation inefficient. Keywords: Rotary equipment, unschedule shutdown, Root Cause Analysis (RCA).

Abstract

Many factors influence a student's success in the academic world. One of them is the role of the lecturer in providing direction or guidance on the problems experienced by students while on campus. Lecturers who act like this are called academic advisors. Lecturers in the formation of student behavior are strongly influenced by the ability of lecturers to communicate. Persuasive communication is an effective communication technique in shaping behavior because by using this communication, students can do something they want without feeling burdened and afraid. Forming behavior is an activity of communication and social interaction between lecturers and students to convey their knowledge in small and large groups. In learning activities, there are teaching techniques so that learning objectives can be achieved. Persuasive communication, in this case, is effective enough to influence or shape behavior.

Abstract

In recent years, the behavior of foreign currency exchange rates (FOREX) has attracted a lot of attention from policy makers, investors, academics and regulators because due to its rapidly changing prices. FOREX predicting based on sentiment analysis has attracted a wide variety of research in finance and natural language processing. The availability of news, social media networks, and the rapid development of natural language processing methods result in better predictive performance. However, new studies related on Rupiah (Rupiah is legal money circulating in Indonesia) sentiment and its correlation with other FOREX are still rare and interesting to study.The purpose of this study is to (1) assess the accuracy of predicting Rupiah sentiment using social sentiment analysis and (2) to investigate the correlation between Rupiah sentiment and IDR currency exchange rate. The methodological approach used for this study is based on social sentiment analysis on Twitter and Pearson correlation.The result of this study is (1) from the seven models that we compared, the Decision Tree (DT) and Random Forest (RF) algorithm models have the best accuracy to avoid misclassification based on AUC. The accuracy measured by F1-score has values of 92.13% for both DT and RF, and (2) Rupiah sentiment has a strong positive correlation with USD (P-value: 0.017, r-value: 0.421) and SAR (P-value: 0.016, r-value: 0.419) exchange rate. On the other hand, Rupiah sentiment has a low significant negative correlation with AUD (P-value: 0.051, r-value: -0.403) and EUR (P-value: 0.079, r-value: -0.479). Rupiah sentiment also has a low but positive correlation with MYR (P-value: 0.073, r-value: 0.180) and is not significant with SGD (P-value: 0.119, r-value: -0.348) although it has a positive correlation. The strong positive correlation represents that the more positive Rupiah sentiment on Twitter, the stronger IDR exchange rate against another foreign currency, and vice versa.
