Abstract

Salah satu proyek yang dijalankan oleh PT. Lutvindo Wijaya Perkasa adalah proyek Pembangunan Jembatan Sei Merangin. Keterlambatan penyelesaian proyek merupakan kondisi yang sering terjadi dan tidak diinginkan. Upaya mengatasi keterlambatan dilakukan dengan optimalisasi waktu dan biaya pengerjaan proyek menggunakan metode Program Evaluation and Review Technique (PERT) dan Time Cost Trade Off (TCTO). Optimalisasi dilakukan dengan menghitung produktifitas pekerja dan biaya lembur pekerja akibat penambahan waktu jam kerja selama 1 jam dan 3 jam. Berdasarkan hasil perhitungan menggunakan PERT dengan penambahan 1 jam kerja dan 3 jam kerja, proyek dapat diselesaikan selama 207 hari dengan percepatan waktu 3 hari dan 188 hari dengan percepatan waktu 22 hari. Sedangkan menggunakan TCTO dengan penambahan 1 jam kerja dan 3 jam kerja, proyek dapat diselesaikan selama 174 hari dengan percepatan waktu 36 hari. Berdasarkan penelitian, metode TCTO lebih efisien dalam perkiraan waktu penyelesaian proyek dan biaya optimal dibandingkan metode PERT. Kata kunci:  biaya, optimum, PERT, TCTO, waktu

Abstract

Transportation activities contributed significantly to air pollution, one of which was a parameter of dust. Workers were exposed to dust in the work environment can lead to accumulation of dust particles in the lungs. Officers street sweeper was a high-risk workers exposed to dust while working, especially in Protocol 3, 4 and 6 of Semarang where approaching the location of the measurement sample ambient air quality that exceeds the threshold value. The purpose of this study was the relationship working duration against lung function disorder on a street sweeper in Protocol 3, 4 and 6 Semarang. This type of research was observational research with cross sectional approach. The population was Street Sweeper in Protocol 3, 4 and 6 of Semarang, amounting to 61 people with a sample of 38 people with purposive sampling method. Results of univariate analysis found an average of forced vital capacity (FVC%) of 84.515%, the average forced expiratory volume in the first second (FEV1%) of 82.875% and an average  of 90.230%. Bivariate analysis of the relationship between the working duration and  lung function disorder  used Chi Square test show p-value of  0,034 (PR = 4.371; 95% CI = 1.074 to 17.79). The conclusion was significant association between the work duration and lung function disorder on street sweeper  in a street sweeper in Protocol 3, 4 and 6 Semarang.  The Suggestions in this study is expected to be a consideration for the relevant agencies in general and the Cleanliness and Landscaping Departement can be used as a reference for the implementation of programs related to the effects of exposure to dust on the street sweeper.

Abstract

Teknologi pengenalan ucapan saat ini telah mengalami perkembangan yang cukup pesat. Teknologi ini memungkinkan suatu perangkat untuk mengenali dan memahami kata yang diucapkan dengan cara digitalisasi kata dan mencocokkan sinyal digital tersebut dengan pola tertentu yang tersimpan dalam suatu perangkat. Pada proses ektraksi parameter suara peneliti menggunakan metode Linear Predictive Coding (LPC). Dari proses parameter suara di hasilkan nilai normalisasi 4160 buah dengan asumsi bahwa waktu yang dibutuhkan untuk pengucapan satu kata dibutuh waktu kurang dari 0,5 detik.  Jumlah frame yang dihasilkan sebanyak 50 buah frame dengan data sebanyak 240 byte data dan jarak antar frame sebanyak 80 byte data dengan overlapnya 160 byte data. Dari proses analisis LPC dilakukan penyimpanan data untuk digunakan sebagai inputan atau masukan diproses pada jaringan saraf tiruan untuk melakukan proses pengenalan. Seratus delapan puluh sampel suara dari sepuluh pembicara yang berbeda digunakan sebagai input proses pelatihan jaringan saraf tiruan. Dua puluh sampel suara dari sepuluh pembicara yang berbeda digunakan sebagai input proses pengujian data baru. Hasil pengujian proses pengenalan suara menunjukkan keberhasilan 75%.Kata kunci : Pengenalan Ucapan, Metode Linear Predictive Coding (LPC), Algoritma Propagasi Balik

Abstract

ABSTRACTThe purpose of this study is to determine the effect of role stress, financial compensation and work motivation on job satisfaction. This research was conducted at Rural Bank in Denpasar. The population  in this research  is all employees  of BPR in Denpasar  City. The sampling technique used accidental sampling obtained on 80 samples used in this research. The results of this study indicate that there is a negative and significant influence between role stress on work  motivation.  The  existence  of  positive  and  significant  influence  between  financial compensation to motivation work is a negative and significant influence between role stress and  job  satisfaction.   The  existence  of  positive  and  significant  influence  of  financial compensation on job satisfaction. The existence of positive and significant influence between work motivation on job satisfaction. The value of direct influence is greater than the value of indirect influence this means that the motivation variable does not mediate the influence of role stress  on job satisfaction.  The value  of direct  influence  is greater  than  the value of indirect influence this means that the motivation variable does not mediate the influence of role stress on job satisfaction. For the company should know what factors that influence the achievement of job satisfaction. Based on the results of financial compensation research and work  motivation  positively  affect  the  job  satisfaction,  should  provide  compensation  in accordance  with  what  is  done  by  employees  /  employees.  This  will  trigger  employee motivation to work better again in the future. When sufficient financial compensation and the achievement  of a good work motivation  will suppress  the role of stress that is owned by employees, the situation will lead to good employee satisfaction.

Abstract

In distribution activities, travel time is influenced by several factors, such as vehicle conditions, traffic conditions and road conditions. Uncertain traffic conditions cause the travel time can not be defined with certainty (uncertain). If several variables are in a uncertain condition then a deterministic approach is not appropriate. Fuzzy approach, can be used to overcome uncertainty conditions. In this study, the optimal route for chicken egg delivery using the fuzzy Multiobjective Cyclical Inventory Routing Problem (FMOCIRP) model with time and cost is expressed by triangular fuzzy numbers. Model completion using Winqsb software. An optimal shipping route is obtained with a total cost of Rp 114,000 and a total delivery time of 132 minutes. The first optimal delivery route is distributor, retailer 1, retailer 2, retailer 3 and back to the distributor. The second route is distributor, retailer 5, retailer 4 and back to the distributor.
