Abstract

The demand for higher bandwidth is increasing along with developments in communication technology. To solve this problem, many parties use optical cables as the backbone of communication network cabling, especially in large data centers. Projects such as FTTH (Fiber to the Home) and FTTB (Fiber to the Building) have also been undertaken to provide better service to customers. In recent years, to take advantage of the future benefits of optical cables, Fiber to the Desk (FTTD) has begun to be recommended specifically for enterprises, financial institutions, and federal agencies. This is because FTTD can provide high security and high data transmission speed. This article will provide a more detailed guide on implementing FTTD and its benefits and designing FTTD using the Cisco Packet Tracer application.

Abstract

The frequency setting is VSD (variable speed drive) or inverter. In controlling the speed of a 3-phase induction motor using a VSD or inverter, the PWM (pulse width modulation) method is used. PWM is a method of manipulating the signal width, which is described by pulses in one period. In collecting data, the methods used are observation, interviews, documentation, and literature studies. The data obtained in the observation are the values of frequency, voltage, and current at the output of the VSD, which goes to the source of the 3-phase induction motor. The results obtained from setting the motor speed by setting the frequency at 25 Hz are 1500 rpm, 30 Hz is 1800 rpm, 35 Hz is 2100 rpm, 39.1 Hz is 2346 rpm, and 40 Hz is 2400 rpm. By adjusting the input frequency to a 3-phase induction motor using a VSD or inverter, it can be concluded that the higher the frequency, the faster the rotation speed of the pump motor, and the resulting water discharge in sucking water will also be greater.

Abstract

Muhammadiyah Ponorogo General Hospital is one of the private hospitals in Ponorogo Regency. At this time the Muhammadiyah Ponorogo General Hospital has received Plenary accreditation from the Indonesian Hospital Accreditation Institute (LARSI). The problem that is often faced by hospitals is that there is a lot of waste that occurs in the service process at the Eye Polyclinic of RSU Muhammadiyah Ponorogo. The most critical level of waste for eye polyclinic services is waiting with a weighting value of 4.00, waste inventory with a value of 3.16, waste overproduction with a weighting value of 3.00, waste defects with a weighting value of 2.91 , waste inappropriate processing with a weight value of 2.66, waste unnecessary motion with a weight value of 2.58, waste transportation with a weight value of 1.41, and waste underutilized abilities of people with a weight value of 2.25. The initial activity time before the repair was 14,677 seconds or 244 minutes (4 hours) and after the repair was reduced to 6,577 seconds or 109 minutes (1 hour 61 minutes). The highest waste is waiting, namely doctors often do not come on time and there is a lack of nurses or pharmacists in the pharmacy with a Risk Priority Number (RPN) score of 252 and 224. Recommendations for improvement that can be proposed are adding doctors to the eye poly department to reduce doctor delays because there are surgery schedules that often collide with the schedule for opening eye poly services and adding medical personnel to the pharmacy department, to reduce queues you can use a drug delivery application that can be accessed by patients without having to queue again at the hospital.

Abstract

CV XYZ is a small and medium company engaged in garment business and headquartered at Jalan Abdurrahman no. 49 RT 15 RW 06, Pabean, Sedati, Sidoarjo. Various types of clothing are produced, such as red and white uniforms as one of its main products. CV XYZ in determining the cost of goods produced is only based on the assumption of the use of materials, tools and wages without considering the details. This situation makes it impossible for the company to know the actual cost of goods produced. This study aims to analyze the determination of production costs that can be used as a basis for effective assessment. The calculation of raw material costs, labor costs, processing costs and electricity costs according to the full cost method shows that production costs have increased compared to the company's provisions. The production cost of the women's red and white uniform is Rp 106,320 and the men's red and white uniform is Rp 108,134. Meanwhile, the price difference obtained for the women's white uniform is Rp 1,320 and the men's red and white uniform is Rp 3,134.

Abstract

The objective of this research is to determine the factors that influence consumer purchasing decisions to buy beverages online on marketplaces. The variables used are product, price, promotion, location, service quality, marketplace usability, and trust. The sample consists of 150 respondents. The Likert scale is used as the data collection model, and statistical analysis is conducted using multiple linear regression. After analyzing the data, this research has obtained results indicating that product (X1), price (X2), promotion (X3), location (X4), service quality (X5), marketplace usability (X6), and trust (X7) have a significant impact on buyer's decisions with a magnitude of 0.732 (73.2%), which means that all variables contribute and affect consumer purchase decisions by 73.2%, while the remaining 26.8% is attributed to other factors beyond the scope of this study. The results of the F-test analysis show that collectively, all variables significantly impact consumer purchasing decisions. The t-test analysis indicates that the research hypotheses for variables X1, X2, X6, and X7 significantly influence consumer purchase decisions, while variables X3, X4, and X5 do not significantly affect consumer decisions

Abstract

The effect of water is very large on the agricultural sector, because with sufficient water the needs of plants are fulfilled so that plants can grow well and can increase agricultural yields. One way to meet the water needs of plants is to design irrigation canals properly to avoid water shortages. The irrigation system in the Kumbung area already has a technical irrigation system and the channel planned is an open channel with a trapezoidal cross section. The area of ​​the tertiary plot in the kumbung area was 146.53.

Abstract

Pacal Dam as one of the infrastructures that has an important role in the life of the people of Bojonegoro Regency. Pacal Dam is one of the providers of water resources in meeting the needs of the surrounding community in irrigation and agriculture aspects. In addition, the Pacal Dam is also a water conservation medium which is one of the efforts to reduce surface runoff originating from the upstream of the river so that flooding does not occur downstream. Therefore, in planning, it is necessary to accurately calculate the stability of the weir. Spiral stability calculations are carried out to determine whether the weir is stable enough to withstand the external forces that occur. Factors that can affect stability include the weight of the weir, active and passive earth pressure forces, and the resulting uplift. In the stability analysis of the Pancal Dam, it was found that under normal conditions the SF (safety factor) result was 1.6082822, while in flood conditions the SF result was 1.55237, where the SF value was > 1.5 so it can be concluded that the weir planning has been able to withstand the overturning moment caused by water pressure, soil, and uplift pressure in flood conditions.
