PENERAPAN DIAGRAM KENDALI MAXIMUM MULTIVARIATE CUMULATIVE SUM (MAX-MCUSUM) PADA PENGENDALIAN KUALITAS PRODUK KACANG (Studi Kasus: Produk Kacang Garing di PT XY)

Now, Statistical quality control be a particular concern to large companies.PT XY is one of the largest nut company in Indonesia that has implemented the quality standards of a product. Max-MCUSUM control chart becomes a tool that is graphically used to monitor and evaluate whether the process is under control or nut. Based on Cheng and Thaga (2005), Max-MCUSUM control chart takes precedence over detecting small shift based on average and variability in industry data. The quality characteristic of Kacang Garing will be variables, namely broken nut skin, bean seed 1, and foam nut skin. Max-MCUSUM control chart is controlled with the control limit (h) from ARL (Average Run Length) simulation of 370 is 429,69. ARL is an average of samples that need to be decribed before it goes out of control. The research continued with multivariate capability process with MCp worth 0,905 and MCpk worth 1,355. Those value indicates that Kacang Garing has met the quality specification stipulated by PT XY. Broken nut skin becomes the most dominant cause based on pareto chart and carried out analysis by using fishbone chart so that is known the main factor causing broken nut skin are machine, material, and method.

Detecting Early Signs of Overtourism: Bringing Together Indicators of Tourism Development With Data Fusion

Tourism is a powerful economic driver for communities, but there are dangers of overtourism in tourism-dependent destinations. The study proposes an approach to detect early signs of overtourism by integrating census and industry data with residents’ perceptions of tourism benefits. The indicators include industry performance, its economic impacts, and indirect measures related to quality of life. The public perceptions are collected through surveying four different tourism-dependent communities in Florida. We found that in general local residents are highly positive about the tourism industry benefits to their communities, yet many respondents would like the tourism levels reduced. Especially concerning are negative sentiments toward tourism among the younger population groups and racial minorities. The findings are interpreted as early signs of overtourism.

NEW PRODUCT DEVELOPMENT OPPORTUNITIES IN REZEKNE

The tourism industry was one of the fastest growing industries in Latvia until the pandemic was declared in 2020, which brought the entire industry to a halt. Before the pandemic, travel trends were already moving towards the type of experience offered by hostels, and consumer demand had grown in the past years. Moreover, the industry data show that the number of travellers who use hostels is growing. There are several lodging opportunities in Rezekne, but there is no economical option, which would be a hostel. The research aim is to study the theoretical aspects of a new product and analyse the opportunities for the creation of a hostel – a new tourism product in Rezekne. The methods used in the research are monographic, synthesis, statistical analysis methods, and a survey. The research allowed making recommendations for the creation of a new tourism product – a hostel – in Rezekne. The results of the research and survey showed that hostel-level accommodation is needed in Rezekne.

Multi-Attribute Assessment of Waste-to-Energy Technologies for Medical, Industrial, and Electronic Residual Wastes

There is a global need for residual waste management to prevent environmental and health hazards and reduce its volume for disposal to sanitary landfills. A waste-to-energy (WtE) facility can provide solutions by converting energy from waste to generate electricity. In this study, a method of selecting the most appropriate WtE technology for residual wastes from medical, industrial, and electronic sectors was formulated and implemented through multi-attribute decision analysis. The preference of the investigators with technical knowledge from different fields of expertise were considered in ranking the most important parameters in the study. From the comparison of seven waste conversion technologies and four power generation technologies, the pyrolysis-Brayton plant was found to be the most suitable WtE technology for residual waste. Using empirical, literature, and industry data, a pyrolysis-Brayton WtE power plant was simulated at capacities of 1, 3, and 10 tons per day (tpd) for the three waste sectors. The results of the study show that a WtE plant can reduce the volume of residual wastes up to 90% and generate electricity up to 1.2 MW for 10tpd plant simulations. The flexibility and small footprint of the pyrolysis-Brayton set-up is suitable for installment in clustered locations. Pilot demonstration is recommended for future studies.

Recovery and Restoration of Biloxi Marsh in the Mississippi River Delta

The State of Louisiana is leading an integrated wetland restoration and flood risk reduction program in the Mississippi River Delta. East of New Orleans, Biloxi Marsh, a ~1700 km2 peninsula jutting 60 km north toward the State of Mississippi is one of few Delta wetland tracts well positioned to dissipate hurricane surge and waves threatening the city’s newly rebuilt hurricane flood defenses. Both its location on the eastern margin of the Delta, and its genesis as the geologic core of the shallow water St. Bernard/Terre aux Boeuf sub-delta, which was the primary Mississippi outlet for almost 2000 years, make Biloxi Marsh attractive for restoration, now that the Mississippi River Gulf Outlet deep-draft ship channel has been dammed, and 50 years of impacts from construction and operation have abated. Now, the cascade of ecosystem damage it caused can be reversed or offset by restoration projects that leverage natural recovery and increased access to suspended sediment from the Mississippi River. Biloxi Marsh is (1) geologically stable, (2) benefiting from increased input of river sediment, and (3) could be restored to sustainability earlier and for a longer period than most of the rest of the submerging Mississippi Delta. The focus of this review is on the Biloxi Marsh, but it also provides a template for regional studies, including analysis of 2D and 3D seismic and other energy industry data to explore why existing marshes that look similar on the ground or from the air may respond to restoration measures with different levels of success. Properties of inherent durability and resilience can be exploited in restoration project selection, sequencing and expenditure. Issues encountered and investigative methods applied in the Biloxi Marsh are likely to resonate across initiatives now contemplated to sustain valuable river deltas worldwide.

Obsolescence of Capital and Investment Spikes

The prospect of capital obsolescence inhibits investment. Investors thus become more optimistic when the obsolescence of their capital slows down. We propose a model with no fixed costs of investment, and random technological progress that induces obsolescence of capital in place. Spikes occur precisely when technological progress slows down. Moreover, the more variable the progress, the larger are the spikes. Cross-industry data show that where price of capital declines are more variable, investment spikes are larger.

Analisis Pengaruh Tingkat Konsentrasi Pasar Terhadap Efisiensi Industri Pengolahan Besar Dan Sedang Di Jawa Timur

This study aims to investigate the effect of market concentration on industrial efficiency. Large and medium processing industry data in East Java and the Stochastic Frontier Analysis (SFA) approach were used to investigate the impact of market concentration on the efficiency of the industry. The results of the study indicate that market concentration in the processing industry in East Java leads to oligopoly. The variable of firm size (FSize) and the level of market concentration (CR4) have a negative effect on the level of technical efficiency of large and medium industries in East Java.

Economic and social impact of Malaysian higher education: stakeholders' perspectives

PurposeThis study examined the economic and social impact of Malaysian universities on their communities from stakeholders' perspectives. It analysed whether university stakeholders' spending, human capital (HC) and knowledge exploration (KE) will impact aggregate income (AI), quality of life (QOL) and business growth (BG) in surrounding communities.Design/methodology/approachA survey was conducted among 540 university stakeholders from the southern, northern and eastern regions of Malaysia, representing the alumni, community and industry. Data were subjected to factor analysis using structural equation modelling (SEM).FindingsResults showed that universities impacted communities' economic development and wellbeing, thereby fulfilling their community-related role.Originality/valueThis study addressed universities' role in communities' economic growth and social development. Universities' contributions towards communities can be improved through the proposed model, which suggests ways to maximise their impact. A more detailed study of a particular university is needed to identify other factors that can strengthen universities' impact, even at national and global levels.

Time spent playing video games is unlikely to impact well-being

Video games are a massively popular form of entertainment, socialising, cooperation, and competition. Games’ ubiquity fuels fears that they cause poor mental health, and major health bodies and national governments have made far-reaching policy decisions to address games’ potential risks, despite lacking adequate supporting data. The concern-evidence mismatch underscores that we know too little about games’ impacts on well-being. We addressed this disconnect by linking six weeks of 38,030 players’ objective game-behaviour data, provided by six global game publishers, with three waves of their self-reported well-being that we collected. We found little to no evidence for a causal connection between gameplay and well-being. However, results suggested that motivations play a role in players’ well- being. For good or ill, the average effects of time spent playing video games on players’ well-being are likely very small, and further industry data are required to determine potential risks and supportive factors to health.
