Abstract

Rural tourism is rapidly gaining recognition worldwide as a catalyst for sustainable regional development, especially in countries seeking to diversify their economies and breathe new life into rural communities. This paper presents a comparative analysis of rural tourism development strategies implemented in China, Turkey, Russia, Kazakhstan, and several Southeast Asian nations, each of which has crafted innovative, context-sensitive models to promote tourism beyond urban centers. These countries demonstrate how effective rural tourism is not the result of isolated projects, but of well-integrated policies that connect culture, nature, economy, and community. This study synthesizes these global experiences into a set of practical, adaptable lessons for Uzbekistan, where rural regions are rich in heritage, crafts, and landscapes, yet remain underutilized in the national tourism agenda. Drawing on qualitative comparative methodology and policy evaluation tools, the article identifies key enablers of rural tourism success: state leadership, inclusive planning, financial incentives, community engagement, and diversified tourism offerings.

Abstract

OPQ is a company that specializes in providing construction materials such as ready-mix concrete, precast concrete, concrete bricks and crushed stone. With 4 different compositions and high demand, it is not uncommon for problems to occur, namely late delivery. This research aims to increase work efficiency by minimizing makespan to reduce idle time which will impact delays in product delivery to customers. The results of production scheduling using the NEH method produce smaller makespan results and faster production process completion times compared to the scheduling method used by the company. The NEH method produces a makespan of 2.29 with the job sequence P3-P4-P2-P1. The method used by the company obtained a makespan of 3.01 with a partial work sequence of P2-P3-P4-P1. This can prove that the calculation results using the NEH method can minimize makespan and this method can be used by companies as a reference for scheduling the production process to overcome the problems being faced by the company.

Abstract

XYZ is a company engaged in assembling agricultural machinery, namely four-wheeled tractors. The components of the four-wheeled tractor itself consist of the front wheels, rear wheels, engine, engine cover, chassis/frame, steering floor, steering seat, fenders, pedals and roof. For parts that will be assembled, the painting process is carried out within the company itself. Therefore, during the painting process, several problems arise, namely differences in color, paint thickness and paint strength. The painting process at this company has not yet reached zero defects, because several defects were still found in the fenders, floor (steering floor), and engine cover. Situations like this can result in increased production costs and decreased product quality, which ultimately reduces profitability. The aim of this research is to find out the main factors that cause defects in painting parts and make appropriate suggestions/improvements to reduce and prevent defects in the painting process. The method used is the Six Sigma method and the FMEA (Failure Mode Effect and Analysis) method. Six Sigma in technical methods is oriented towards a statistical approach to calculating product defects. The goal is to reduce process variance by eliminating defects that interfere with customer satisfaction. FMEA is a technical analysis which, if carried out correctly and at the right time, will provide great value in helping the decision making process. The research results show that the average DPMO value for tractor product production on weekdays from January 1 2023 to April 30 2023 is 107618.46 with an average sigma value of 2.74. The recommendation for improvement from the FMEA method is that the cause of the defect with the highest RPN value is painting that does not comply with the SOP of 576. The proposed improvement for the cause of this defect is supervision of painting employees.

Abstract

Everyone uses transportation as a means of getting to different locations. There are three categories for the actual modes of transportation: air, sea, and land. People typically use ground transportation, such buses, cars, and bicycles, for daily errands and commutes to the office since these modes of transportation are more convenient and quick to use. The electric bicycle is one of the vehicles that is currently being developed. The development of electric bicycles is necessary since they are simple and comparatively inexpensive to produce. Naturally, an electric bicycle needs a motor to propel it. A DC motor needs a voltage that enters the field coil in the same direction in order to generate mechanical energy. Electromotive force is produced by the armature coil while magnetic force is produced by the field coil. When the armature coil current interacts with the magnetic field, it produces the torque (T) that powers the motor. A DC motor has windings, and the quantity of windings in the motor can change its torque and output. The author of this study employs a DC motor, and alterations are planned to the windings through both an increase and a decrease in winding count. The objective is to ascertain how a 250W electric motor's torque and power are affected by the number of windings. According to the study's findings, the torque and power obtained at the start of the standard winding test were 0.55 and 5.7, respectively, when the RPM reached 100.4. When the rpm hits 77.8, adding coils results in a torque of 0.55 and a power of 4. When the rpm reaches 131.3 and the torque is 5.5, the power is 7.5 after the coils are reduced. Thus, the rpm and power generated decrease with the number of windings. Both the resulting rpm and the power released are inversely proportional to the reduced winding.
