ROLE OF FARMERS GROUPS IN INCREASING SUSTAINABLE RICE PADDY FARMING BUSINESS IN LUBUK BAYAS VILLAGE OF PERBAUNGAN SUBDISTRICT

Farmer groups as a forum for organization and collaboration between members have a very important role in the life of the farming community, because all activities and problems in farming are carried out by groups simultaneously. With the existence of farmer groups, farmers can jointly solve problems which include the fulfillment of agricultural production facilities, technical production and marketing of products. Seeing this potential, farmer groups need to be fostered and empowered further in order to develop optimally. In increasing rice production, it is necessary to preserve the production environment, one of which is through the use of organic fertilizers. Various forms and materials of organic fertilizer can be applied depending on the availability at the farm location. In an effort to improve sustainable farming, The things that are applied are increasing productivity in farming activities and the use of superior seeds, the use of fertilizers, pesticides and the application of cooperation for the manufacture of fertilizers so that group members do not need to buy fertilizer. The existence of institutions/KUD in a village is very helpful for farming communities because these institutions can also take capital loans for farmers so that farmers are able to provide good production facilities, which so far farmers have only relied on outside capital, which is not certain whether they can afford it. continue to cooperate with farmer groups.

The future of Swiss run-of-river hydropower production: climate change, environmental flow requirements and technical production potential

Run-of-river (RoR) hydropower is essential in Alpine energy production and highly sensitive to climate change, due to no or limited water storage capacity. Here, we estimate climate change impact on 21 RoR plants in Switzerland, where 60% of the annual electricity is produced by hydropower (30% by RoR). This is one of the first comprehensive, simulation-based studies on climate change impacts on Alpine RoR production, including effects of environmental flow requirements and technical production potential. We simulate three future periods under three emission scenarios (RCP2.6, RCP4.5, RCP8.5). The results show an increase of winter and a decrease of summer production, which in conjunction leads to an annual decrease. The simulated impacts strongly depend on the elevation and the plant-specific characteristics. A key result is that the climate induced reduction is not linearly related to the underlying streamflow reduction, but is modulated by environmental flow requirements, the design discharge and streamflow projections. Stronger impacts are expected if climate change affects streamflow in the range that is usable for production. This result is transferable to RoR production in similar settings and should be considered in future assessments. Future work could in particular focus on further technical optimisation potential, considering detailed operational data.

High- and Ultra-High-Purity Aluminum, a Review on Technical Production Methodologies

Aluminum and aluminum-based alloys have been used for many years. In view of the increase in material purity requirements of advanced technology products, research regarding high-purity aluminum has gained significant attention in recent years. In this review, we seek to describe the fundamental purification principles and the mechanisms of various segregation techniques used to produce high-purity aluminum. Moreover, we aim to provide an overview of high-purity aluminum production, with particular emphasis on: (a) principles on how to produce high-purity aluminum by layer- and suspension-based segregation methods; (b) discussion of various influencing process parameters for each technique, including three-layer electrolysis, vacuum distillation, organic electrolysis, suspension-based segregation, zone melting, Pechiney, Cooled Finger, and directional solidification; as well as (c) investigations of fundamental working principles of various segregation methods and corresponding reported end-purification for the production of HP-Al. Eventually, the end-reported product purity, and advantages and disadvantages of various purification methods and technologies are summarized. By analyzing and comparing the characteristics of different methods, we put forward suggestions for realizing efficient and environmentally friendly production of high-purity aluminum in the future.

Identifying competencies for future graphic design graduates in Malaysia: A Delphi study

Traditionally, graphic design (GD) education focuses on the training of technical production skills to prepare graduates for entry-level employment. However, due to the new challenges and the expanding opportunities of emerging practices, GD graduates are expected to master a wide range of additional competencies beyond traditional scope. The study aims to identify the competencies required by future GD graduates in the context of Malaysia. A two-round modified Delphi technique was used to gain consensus from a panel of experts consisted of design educators and industry practitioners regarding the competencies needed by the graduates for effective work performance. A total of 108 competencies were generated. All accepted competencies were ranked ‘very important’ and ‘extremely important’ by at least 75 percent of the respondents in Round Two. These competencies could be classified into 29 subdomains under five components, i.e., cognitive competence, functional competence, personal competence, ethical competence, and meta-competencies. The findings of this study are useful for enhancing the education and employability of graphic designers as they provide a common vocabulary to relevant stakeholders about the standards of performance for new entrants to the GD profession.

Development of beef cattle breeding in the Republic of Tatarstan

The objective possibility of increasing beef production due to the development of beef cattle breeding is determined by natural and economic factors, both in Russia and the Republic of Tatarstan, the presence of huge areas of natural forage lands and cultural pastures, which allow for full-fledged feeding of cattle throughout the calendar year with a full-fledged balanced feed diet. The material and technical production base in the agricultural sector of the Republic of Tatarstan at this stage fully meets the requirements of technological approaches to expanding the number of beef breeds of cattle (cattle) in this region, both in large agricultural enterprises, farmers, households and individual agricultural entrepreneurs. At the present time, the Republic of Tatarstan clearly shows the trend of long-term development of the beef cattle industry. However, in the current situation, the main share of beef in the Republic of Tatarstan is produced by agricultural organizations and representatives of small agricultural businesses engaged in the breeding of dairy and meat cattle. In the context of the introduction of innovations in the organization of agricultural production, industrial crossing of dairy cows with purebred bulls of meat breeds is used as one of the directions for the growth of beef production.

Hubungan Antara Komunikasi Dalaman Dan Penglibatan Pekerja

This study was aiming on examining the relationship between internal communication and employee engagement. Specifically, this study identified the level of organizational and supervisory communication and the level of employee engagement. In Johor Bahru, a total of 169 employees in only one factory participated in the study, representing their various departments including department of accounts, technical, production, and administration. Therefore, data was being analyzed using descriptive statistics and correlation analysis. The result indicated that perceived internal communication has positive relationships but weak in employee engagement. Also, descriptive analysis revealed that both internal communication and employee engagement level were high.

The complexity of barriers to biogas digester dissemination in Indonesia: challenges for agriculture waste management

In the global south, the use of firewood and LPG as dominant energy sources for cooking contributes to socio-ecological issues. Alternatively, biogas is considered a clean energy source generated from organic waste. However, in Indonesia, until 2018, only less than 2% of households utilized biogas for cooking fuel. This research aims to explore the landscape of biogas governance in Indonesia, its fragmentation, and its relation with biodigester dissemination. This study found that there is fragmentation within small-medium scale national biogas programs in Indonesia. Seven national government biogas programs have similar governance arrangements and characteristics; scattered in different departments within the ministry, using the grant approach with two main vendors, often overlapping with local government programs, and not providing proper monitoring and evaluation mechanism, as well as proper training for users. Meanwhile, the biogas program by a non-government organization utilizes a semi-commercial approach; collaborating with multiple stakeholders (governments, local construction partner organizations, cooperatives, and private sectors-companies and banks); and has standardized training and after-sale services. Within those biogas programs, there are multiple barriers along the supply chain process of biodigester dissemination. These barriers relate to the governance aspect of biogas programs. Fragmented governance affected the capability of each program to tackle barriers in biogas digester dissemination. Besides, heavy subsidy on LPG by the government reduced attraction to biogas. This study shows technology adoption barriers beyond the user/individual aspects. It shows interaction among different factors such as policy, the governance of technology transfer, technical production issues, and socio-cultural problems.
