Abstract

Abstract  Cycle Time is a matter that must be considered in production time, a good Cycle Time will support the targets that must be met, even if Cycle Time decreases, production will also increase and company turnover will also Increase. In the case study of PT Arisamandiri Pratama, one of its productions is in the form of AC parts, namely capillary pipes which still use a manual rotating table to rotate the pipe to be welded so that it is unable to reach the target of 800 parts / hour with an average Not Good product of 93 parts / day. The design of an inverter-based electric rotary table can reduce cycle time, but how much frequency will affect the results of a welding, not that the faster the welding process the better, the faster the welding will affect the vibration of the table machine which will have an impact on the welding results. By experiment the inverter frequency setting is expected to get a frequency value with maximum speed but no vibration on the rotation table, the frequency used is between 700 Hz to 1500 Hz with an interval of 100 Hz. The experimental results show that the best frequency is 1000 Hz, with a rotation speed of 16 rpm with a production capacity of 935 parts / hour with Not Good products of 59 parts / day or a decrease in Not Good products by 42.1% per day

Abstract

This research aims to identify the ways in which the urban regulations of Padang Beach have affected the ways in which street sellers do business. The author carried out this study by employing descriptive qualitative methods. Interviews and documentation are the means of data collection employed in this study. After completing the data reduction, data presentation, and conclusion drawing steps of the data analysis process, conclusions were drawn. This study draws on Blackman's theory of urban policy, which focusses on public service provision and access improvement in metropolitan areas. According to the study's findings, both enabling and limiting variables impact the implementation of street vendor arrangements from an urban policy standpoint. The problems faced in structuring street vendors are regulations and institutions, availability of land for developing facilities, empowerment and supervision and partnerships and the role of the community. So, to fix issues with street vendor management in the Padang Beach region, we need a more holistic and coordinated approach.

Abstract

Sustainable fertilizer practices are needed in the context of resource degradation, climate change and population growth. Farmers' decisions to adopt sustainable agricultural practices are influenced by economic, psycho-social and technological availability aspects. This research aims to explain the factors that influence farmers' decisions to adopt sustainable fertilizer practices. The research model uses the basic Technology Acceptance Model (TAM) and adds the socio-cultural dimension of farmers. The research was carried out by taking the case of shallot farmers' decisions regarding the use of fertilizer. The research was carried out using a survey approach of 111 shallot farmers taken using proportional sampling in the shallot production center of Brebes Regency, Central Java, Indonesia. Data were analyzed using Structural Equation Modeling-Partial Least Square (SEMPLS). The research results found that farmers' attitudes towards adopting sustainable fertilizer practices were influenced by factors such as perceived usefulness, perceived ease of use, and social influence, while farmers' intentions to adopt sustainable fertilizer practices were influenced by farmers' attitudes and habits. The conclusions of this study have implications for technological development and socio-cultural aspects to scale up sustainable fertilizer practices.
