Authors: Handayani Catur Budi , Purwati Catur Suci
Published: August 2024

Slaughterhouses are known as places to produce meat for human consumption. On the other hand, slaughterhouses produce livestock waste, one of which is rumen. The rumen's high nutrient and microbial content provide an excellent opportunity for its use as liquid organic fertilizer for plant growth and development. However, evaluation of rumen addition concentration during the manufacture of liquid organic fertilizer is still scarce and needs to be carried out. Therefore, this research aims to obtain a suitable rumen addition formulation for making liquid organic fertilizer. Rumen waste was varied in 4 concentrations, namely 20%, 40%, 60% and 80%. Supporting ingredients, such as laos, ginger, turmeric, galangal, and rice washing water, are mixed with the rumen, which is then incubated for 15 days to obtain liquid organic fertilizer. Analysis of total nitrogen content, C/N ratio, total phosphate, total potassium, total microbes, and physical characteristics was carried out to evaluate the quality of liquid organic fertilizer. The results showed that the addition of 80% rumen was able to play a role in producing liquid organic fertilizer with high total nitrogen (2.35%), low C/N ratio (6.05), high total phosphate (1.19%), and high total potassium (1.75%). Furthermore, liquid organic fertilizer made with the addition of 80% rumen contains high total microbes (5.5 x 1010 CFU/mL), is bright brown, yellowish in color, and has an earthy aroma. This research indicates that adding 80% rumen can produce good quality liquid organic fertilizer. This information can be the basis for further research regarding the rumen potency as an ingredient of organic fertilizer.

Published: August 2024

This study explores the dynamics of local communities in Pancasari Village, Buleleng, Bali, as they transition from traditional agriculture to the emerging camping sector. This transformation has led to significant economic, social, and environmental changes within the community. Economically, the shift has generated new employment opportunities, increased household incomes, and stimulated local businesses, thereby enhancing the village’s economic resilience. However, challenges such as potential inflation, uneven distribution of benefits, and increased vulnerability to external economic shocks have also arisen. Socially and culturally, the move to camping has altered traditional roles and lifestyles, facilitated cultural exchange and the introduction of new ideas but also posing risks of cultural dilution and commodification. Environmentally, the camping sector promotes sustainable tourism practices, yet it also brings negative impacts like habitat loss and increased waste. This study employs a qualitative research methodology, including interviews, observations, and document analysis, to understand these dynamics comprehensively. The findings highlight the need for sustainable planning and inclusive development strategies to address economic challenges, robust environmental management to mitigate negative impacts, and effective policy and governance frameworks to ensure equitable benefit distribution and stakeholder coordination. The study concludes that while the transformation to the camping sector presents significant opportunities for economic growth and cultural exchange, it also requires careful management to ensure long-term community well-being and sustainability. By understanding these dynamics, policymakers and stakeholders can better support the community through this transition, promoting balanced and sustainable development in Pancasari Village.

Der Wert der Gleichheit
Authors: Wintermantel Vanessa
Published: August 2024

Die größte Gefahr des autoritären Populismus für die liberale Demokratie besteht darin, dass er die politische Gleichheit aller Bürger*innen zu verneinen versucht. Häufig wird die liberale Demokratie mit ihren Institutionen und Verfahren gleichgesetzt. Was die liberale Demokratie im Kern auszeichnet – dass sie ihren Bürger*innen den Status als freie und gleiche Mitglieder des politischen Gemeinwesens gewährt – gerät so manchmal in Vergessenheit. Dabei ist es gerade dieses demokratische Grundprinzip, das autoritäre Populist*innen in Deutschland und darüber hinaus heute angreifen.

The chiefs and people of the Klikor Traditional Area in the Volta Region of Ghana celebrate the Fiasidi tradition, an annual religious and cultural festival. A yearly ritual performance known as Tagbayiyi (pilgrimage to the sacred grove) is a part of the Fiasidi tradition. Despite the abundance of research relative to the human and cultural rights aspects of the Fiasidi tradition, there is a glaring lack of research on the aesthetic elements reflected in the Tagbayiyi ritual performance. The study investigated the aesthetic aspects of the Tagbayiyi ritual by highlighting its visual and performing arts to gain a deeper understanding of the Anlo-Ewe cultural identity. The study employed a qualitative ethnographic design to interact and access the viewpoints of the participants. A total of fifteen (15) participants, comprising high priests, tradition keepers, ritual functionaries, and supplicants in the Klikor Traditional Area were sampled using a homogenous type of the purposive sampling approach. The study found that the Tagbayiyi exhibits aesthetic elements such as indigenous costume regalia, sacred stools, local beads, priestly emblems, rhythmic and graceful musical dances among others, which symbolically represent the sociocultural identity of the Klikor people. The study, therefore, recommends that the leadership of Klikor (high priests, council of elders & ritual functionaries) should liaise with the Ghana Museums and Monuments Board, Ghana Tourism Authority, National Commission on Culture, and other cultural institutions to preserve and promote the rich aesthetic elements showcased during Tagbayiyi rite for the benefit of the current and future generations of Klikor.
Validation procedure for numerical model of hydraulic inflatable dam under pulse load
Authors: Iliev Veselin , Nikolov Nikolov
Published: August 2024

Hydraulic inflatable dams are cylindrical dams, formed by load bearing rubberized fabrics, placed across streams to raise the upstream water level when inflated. During operation, they are exposed to the water flow and its static and dynamic characteristics. While the behavior of these structures under static load is well studied, the dynamic load is still under investigation. This is particularly emphasized when the water flow is in the form of wave causing pulse load. Such behavior is difficult to being studied analytically and usual method here is a numerical simulation. This article presents a validation procedure for a model for numerical simulation of a hydraulic inflatable dam under pulse load, caused by water wave. The used software is ANSYS CFX. The experimental equipment and experimental procedure are described for short, two-side fixed dam in a rectangular bed. Visual and numerical criterions are proposed in order to estimate the adequacy of the model.

Some aspects of translation skills acquisition in a specialized context
Authors: Koteva Galina
Published: August 2024

The concept of translation competence is a term covering the various skills and knowledge that a translator needs to have in order to translate functionally. It has been proposed as an umbrella term to cover the needs of translation business and is based on the technical skills, conceptual skills and interpersonal skills which a translator should have in order to choose the best way to solve transla- tion problems. In this paper a questionnaire of translation competence questions concerning student perceptions was used as an empirical data collection tool in quantitative research. The questionnaire consists of three sections each of them aiming at finding the students’ attitudes to their translation skills. The results can be used to enhance the curriculum design of the subject of English as a foreign language in which engineering students should master translation skills. A model devised for professional transla- tors is used with non-professionals students where the primary purpose of teaching translation skills is to measure and assess the acquisition of linguistic competence.
Priority estimation of quality indicators in hazardous wastes management
Authors: Borisov Dimitar
Published: August 2024

Hazardous Waste Management is a complex task involving multiple target parameters. Each one of them has a certain meaning, but it is not sufficient to determine the optimal management of hazardous waste. The optimal values of the different target parameters are obtained at different values of the plurality of control parameters. Some approaches reduce the task to one main target parameter, and others are presented as regional constraints, but this is not always possible. Optimal decisions in multicriteria optimization problems in quality control greatly depend on priorities and weight coefficients Wj, adopted for the various quality characteristics. There are no strictly formalized methods for estimation of importance, priority and weight coefficients. Two questionnaires with 10 quantitative indicators are developed. Priorities and weighting factors are determined by ranking the quality indicators. Coefficients of concordance have been calculated and their significance has been estimated.

Temperature-diffusion analogy in fracture analysis of ceramic products during the drying process
Authors: Iliev Veselin , Zheleva Mihaela
Published: August 2024

This article presents an approach, combining fracture mechanics and temperature-diffusion analogy, to assess the initialization of cracking and the crack propagation in the drying process in the production of ceramic products. The correspondence between humidity and temperature in the resolving equations of the two processes is used as a basis for the temperature-diffusion analogy. These equations were solved using the “Transient Thermal” and “Static Structural” modules of the ANSYS Workbench software. The mechanical properties of the material necessary for the realization of the solution (coefficient of thermal conductivity and diffusion coefficient) are taken from literature sources. From the model temperature solution, results were obtained for the temperature distribution, which shows the picture of the moisture content in the real drying process. Results for deformations and mechanical stresses in the material have also been obtained. By introducing a crack and applying the apparatus of fracture mechanics, the values of the stress intensity factor at different crack orientations were obtained. The obtained results can be used to optimize the drying process and reduce product defects.

Application of the liquid-liquid extraction method and subsequent icp-ms detection for speciation analysis of arsenic in wastewater samples
Authors: Stefanov Eduard , Georgieva Stela
Published: August 2024

The current paper describes a method for determining As(III) and As(V) concentrations in wastewater samples. The approach is based on the extraction of As(III) from water samples using a non-polar organic solvent in a 10-12 M HCl medium. The extract contains As(III), while the raffinate contains As(V). Distilled water can be used to re-extract As(III) from the organic solvent. ICP-MS was used to analyze As concentrations in the reextract and the raffinate. The average recovery of arsenic by the proposed method is 99.6 %. It was calculated as the sum of As(III) and As(V) concentrations. The collected data demonstrated high repeatability. The standard addition procedure demonstrated the selectivity and accuracy of the employed method. The relative error of recovery of the standard As(III) addition is about 2 %, which is similar to the RSD found under repeatability conditions.

The research was conducted using qualitative research methods, namely interviews and internet sites. Data results obtained through interviews. The research results show: LGBT is a sexual deviation, which cannot be denied, Christians also fall into it. LGBT behavior is an abominable act in the eyes of God. This creates negative things in people's lives and health. Parents play a very important role in educating children, providing correct sex education that is in accordance with God's Word. This LGBT group has the right to repentance in Jesus. Because that is why Jesus came into the world to save humans from sin. The church also has a very important role in providing assistance to LGBT groups.
Prinsip Pengembalaan Berdasarkan 1 Petrus 5:1-4 Dan Impilikasinya Bagi Pelayan Gembala Masa Kini
Authors: Josep Lumbantoruan  , Adi Suhenra Sigiro
Published: August 2024

The pastor is a leader for the congregation who thinks about the spirituality of the congregation and also the physical needs of the congregation he serves. Therefore, the pastor's service to the congregation is a holistic service. If the congregation served by a pastor has problems in terms of spirituality or life needs, the pastor must be willing to carry out visits and counseling. Considering that the responsibility of pastoral care is quite large, being a pastor must be a calling in life. However, it is very ironic that there are still pastors today who do not serve the congregation totally. This article is a qualitative method by examining God's servants or Shepherds as leaders. The principles of shepherding are based on 1 Peter 5:1-4, namely serving without seeking one's own interests, serving voluntarily, serving with enthusiasm and providing an example to the sheep or congregation.

A new low-sugar yogurt with carrot jam was developed by reflecting consumers’ demands of yogurt and the characteristics required for the development of new yogurt. To examine the storage stability of yogurt containing carrot jam, the yogurt was stored in a refrigerator at 4°C for 21 days, and changes in pH and titratable acidity were examined at 3-day intervals. Nine nutrient contents of yogurt were analyzed to compare the sugar content of the control and carrot jam-added yogurt. Considering the health functionality of new yogurt, when questioned about the appropriate amount of sugar content in yogurt, numerous respondents indicated that they wanted the sugar content to be reduced by about 1 to 5% (73.3%) compared with existing products and that the taste should remain similar to existing products (32.2%). The pH and titratable acidity of yogurt with 4% carrot jam were measured during storage, and it was found that the yogurt had excellent storage properties up to the twenty-first day of production. According to the result for the nutrient contents of yogurt with 4% carrot jam, it was found that the total carbohydrate content, including the dietary fiber content of carrots, was 9.3% while the sugar content was 4.7% which was lower than the sugar content of the control group of 7.0%. Considering the above results, it is expected that the consumption of Jeonnam regional specialties will be promoted through commercialization research on yogurt with carrot jam, which can meet consumers’ health needs and perceptions toward the new yogurt.
