Abstract

Auskultasi merupakan teknik untuk mengukur suara jantung. Suara jantung didengar dengan penggunaam stetoskop yang dihasilkan dari getaran setelah penutupan dan pembukaan suara jantung. Pengukuran suara jantung dilakukan di area katup aorta dan pulmonary. Frekuensi suara jantung berada di frekuensi 20-500 Hz. Suara pertama yang didengar adalah suara jantung pertama S1 terjadi pada awal sistole ventikular dan suara S2 terjadi pada akhir systole ventikular. Pada penelitian ini frekuensi yang didapatkan dalam kalkulasi transformasi fourier pada frekuensi 250-300 Hz

Abstract

o reveal the workers comfort in doing the job activity on the loom, it is necessary to know standard output produced by the workers during a workday, the energy consumption required in work activities that can increase productivity and examine the complaints and sense of fatigue on the weaving machine operators. Results of processing of standard working hours operating time to complete 60 meters of plastic sacks subjectivity takes 69.79 minutes. And heart rate (physiological performance) before work will be conducted comparisons of the energy when the operator works with estimated energy expenditure 2.3 kcal / min from the results of this comparison is the average energy expenditure has been insufficient demand service or standards issued by Lehman. This is caused by conditions that are not too many movements such as ergonomic work and the workload that must be borne by the body especially the legs, hands, arms and shoulders.

Abstract

In Indonesia, one of the companies that produces and supplies fuel is PT Pertamina (Persero). Pertamina continues to develop new service standards to ensure consumers get the best service. SPBU (Public Fuel Filling Station) is a private party working together as a means to distribute products produced by Pertamina. This study aims to determine the effect of service quality on customer satisfaction at local gas stations and to determine the most dominant factor influencing customer satisfaction at local gas stations, using 68 respondents of this study using linear regression methods and t test. Linear regression with equation Y = 3.263 + 0.192X. Based on the results of calculations from the statistical t test between service quality variables on customer satisfaction, obtained t value of 1.787 and t table value of 2.00 This means t arithmetic <t table (1,787 <2.00), meaning that there is no influence on service quality to customer satisfaction, which means that Ho is accepted and Ha is rejected. so, in this case it can be concluded that there is an influence of service quality on customer satisfaction with a significance value of 0.078> 0.05, then Ho is accepted and Ha is rejected, it means there is no influence of Variable X (quality of service) on customer satisfaction (variable Y) so, in this case it can be concluded that there is no significant effect of service quality on consumer satisfaction at the Lala gas station.

Abstract

Ambon city, which mostly consists of hilly areas, is an area that is very highly susceptible to the occurrence of debris mass movements, both in the form of debris flows and landslides (debris flows, erosions, and slope failures). In the city of Ambon, rivers are passed such as Way Ruhu, Way Batu Merah, Way Tantui, Way Tomu, Way Batu Gajah and Way Batu Hang. The purpose of this paper is to plan the check dam building for Way Batu Merah – Ambon City. The method used is Hydrological Analysis: hydrology as the basis for planning the Q25 Check Dam Building, which consists of rainfall analysis and the basis for calculating the planned discharge used in planning, using the Sabo Technical Center method. From the calculation results, it is obtained that the planned Q25 flood discharge of the Way Batu Merah River is 516.43 m / year with a return period of 25 years, the sediment volume can be accommodated 22,102 m / year and controlled by the Check Dam 56,050 m / year, then with a sediment discharge of 60,685 m³ / year . By comparing the amount of sediment that enters the Check Dam with the capacity of the Check Dam, it is dredged again for 3.5 years.

Abstract

Persaingan yang semakin ketat terjadi di dalam dunia otomotif khususnya produk sepeda motor, karena produk ini merupakan alat transportasi darat yang paling dominan banyak dimiliki dan dibutuhkan oleh masyarakat. Memang tidak mudah menjadi yang terbaik, selain harus menyediakan kualitas terbaik juga ada faktor pola perilaku konsumen yang tidak mudah ditebak, apalagi di Indonesia yang terdiri dari banyak pulau, sehingga memiliki ragam pola perilaku yang berbeda pula. Bengkel merupakan salah satu faktor utama bagi masyarakat dalam memenuhi kebutuhannya akan layanan perbaikan dan perawatan kendaraan yang mereka miliki. Untuk mengetahu kepuasan pelanggan dalam pelayanan maka penulis membuat penelitian dengan tujuan untuk mengetahui tingkat kepuasan konsumen terhadap kualitas pelayanan yang diberikan oleh Bengkel Kurnia Motor dan untuk mengetahui faktor pelayanan apa saja yang perlu di tingkatkan Bengkel Kurnia Motor untuk meningkatkan kualitas pelayanannya. Dari hasil pembahasan pelayanan sangat berpengaruh terhadap kepuasan pelanggan dilihat dari uji korelasi sebesar r hitung 1,0 > r tabel 0,387, maka dapat disimpulkan bahwa ada hubungan atau korelasi antara variabel pelayanan dengan variabel kepuasan, maka perlu faktor perbaikan pelayanan diantaranya membuat ruangan tuggu yang aman, menyediakan tempat parkir dan memberi garansi kepada pelanggan.
