The present study was conducted to investigate the effect of color (white and blue-green) of LED lighting on the productive, carcass and behavior traits of Cobb broiler chickens. Total of 200 one- day-old unsexed chicks were used, and divided into two pens/groups (100 birds of each with 25 birds of each replicate), at stocking density of 8.7 bird/ square meters. First pen used for LED white color and second pen for LED blue- green mix color light. The results showed that the birds exposed to blue-green light had significant higher (P≤0.01) BW, DBWG and FC values of the whole experimental period compared to those exposed to white color. However, the light color had no significant effect on FCR and MR measurements with average values 1.44 and 0.50%, respectively. The birds exposed to blue-green light had significant higher pre-slaughter live BW and carcass weights (P≤0.01) compared to those exposed to white color. The birds exposed to blue-green light had higher insignificant dressing percentage compared to those exposed to white color. The weekly behavior results showed highly significant differences (P≤0.01) among weeks for aggressiveness and immobility activities, while it being insignificant for pecking activity. The correlation value between immobility and five-week BW of birds reared under blue-green light was the only significant value (0.42) among all studied values. In conclusion, the results indicated that Cobb broilers were calmer under blue-green light compared to those reared under white light, which contributed in more better performance traits.

Published: May 2023

As “terras de herança” do Médio Jequitinhonha se constituíram a partir de relações que articularam processos e modalidades hegemônicas de apropriação do espaço às formas locais colonizadas de produção dos “territórios sociais”. A exposição às experiências históricas de expropriação e a exiguidade de seu território conformaram um quadro de intenso agenciamento sobre a disposição e a transmissão da terra, compondo uma gramática local de costumes sucessórios orientados para a garantia da reprodução social das famílias. Estas localidades compreendem, hoje, domínios espaciais de pertencimento reconstruídospoliticamente no campo silencioso e cotidiano da gestão de seus recursos. O ensaio procura examinar as práticas costumeiras de gestão dessesterritórios, sobretudo, suas estratégias sucessórias assentadas sob um conhecimento prático, costumeiro e localizado cujas expressões tomama forma de disposições éticas e afetivas assimiladas ao discurso genealógico e à memória coletiva, registros que asseveram a legitimidadede seus direitos territoriais.

Published: May 2023

Traffic jams are common in developing countries. This is generally caused by traffic density, road conditions, and the driver's personality. This phenomenon can be simulated using a mathematical model, allowing it to be seen how these factors affect traffic conditions. The goal of this study is to simulate the effect of traffic density and road conditions using the Lighthill-Whitham-Richard (LWR) model. This model is used to describe macroscopic traffic flow conditions, which are affected by traffic density and speed. The Greenshield model with the influence of road condition parameters added is used for the speed. In numerical solutions, the Upwind method is used to evaluate midpoint values. The simulation results demonstrate the model's ability to describe traffic conditions that are affected by traffic density and road conditions. The level of traffic density is inversely proportional to road conditions and traffic speed.

Published: May 2023

The United States (US) is one of beef exporting countries in Japan. The high level of demand for beef in Japan was followed by a decrease in the volume of US beef from Japan during 2017-2020 period caused by import barriers in the form of tariffs faced by US beef. These tariff barriers arise because the US does not have a trade agreement with Japan. This study aims to discuss the efforts made by the US through negotiating tariff barriers with Japan regarding beef exports. This study uses the concepts of economic diplomacy and trade theory as the basis for research analysis. The research method used in this research is descriptive qualitative with data collection through documentation study. The results of this study indicate that the US effort in negotiating tariff barriers with Japan is to form a bilateral trade agreement, namely the US-Japan Trade Agreement (USJTA) which uses the stages of decision-making in economic diplomacy in its formation. Through this effort, the US successfully lowered its beef import tariffs in Japan and leveled its beef competitive level with the CPTPP member countries. In the formation of the USJTA, various actors are involved, both state and non-state actors. Efforts to negotiate tariff barriers on beef exports by the US and Japan succeeded in increasing US beef exports after the establishment of the USJTA began to be implemented on January 1, 2020.

Published: May 2023

The issue of humanitarianism in international relations is a vital topic to probe deeper. Activist groups, individuals, and institutionalized groups or organizations, such as the United Nations International Children's Emergency Fund (UNICEF), have been carrying out humanitarian actions in Papua. UNICEF has been around for a long time in Papua, running several programs, including children's education program in Papua. However, education in Papua remains relatively low due to high rates of illiteracy and school dropouts, and poor literacy. This research explains that international organizations working in the humanitarian field can carry out the basic principles of humanitarianism, specifically, how UNICEF's programs adhere to these principles during the Covid-19 era. Direct interviews and secondary data collection were conducted in this qualitative descriptive research. The results show that UNICEF, as an international humanitarian organization, managed to uphold four basic principles in carrying out its role, particularly in improving the quality of education in Jayapura City. However, the Covid-19 pandemic has posed such obstacles to UNICEF related to donors, program implementation, and personnel that the practiced humanitarian principles became blurred and somewhat questionable. While the best practice promotes faithful adherence to the basic principles of humanity, it is undeniable that almost all organizations cannot exist without assistance from third parties which would ignore the principle of impartiality.

Analyzing the Rationality of Ethiopia in Dealing with China’s Support in Infrastructure Development
Authors: Hairisa Ahda Ayudia , Farid Muhammad 
Published: May 2023

This article analyzes the rationality of Ethiopia in cooperating with China in restoring the Addis Ababa-Djibouti railway project using rational choice theory in foreign policy making. Despite having several alternative ports and other parties to support the project, Ethiopia has chosen the fund from China to support its railway project. The similarity between China and Ethiopia regarding political values is one of the factors in choosing China to work with. The Ethiopian People’s Revolutionary Democratic Front (EPRDF) seems to be unapproachable by Western political values that are influenced by the internal condition of the state and tend to emphasize democracy. Therefore, it tends to work with China. Other than that, depending on Djibouti’s port as the most viable seaport in the region to access the sea as a landlocked country has driven Ethiopia to restore the railway as quickly as possible. By considering the Chinese loan system, which did not have many qualifications to lend money, Ethiopia could quickly restore the railway and not miss out on the opportunity to grow its trade through developing its infrastructure.

Published: May 2023

The practice of child labor is included in the form of violations of human rights so that it requires special attention and is handled seriously. The ILO as an international organization with a focus on child labor issues in the world certainly plays an important role in dealing with phenomena related to child labor, not only on a global scale but also on a national scale of its member countries, including Indonesia. This article aims to find out how the role of the ILO in dealing with the problem of child labor in Indonesia (2017-2021) uses Clive Archer's theory of the role of international organizations as an analytical tool. The method used is a qualitative method and is explained through descriptive analysis. The results of this study explain that in dealing with child labor in Indonesia, the ILO has acted as an instrument, an arena, and an actor. Through these three roles, the ILO has been able to carry out its role quite effectively so that the practice of child labor in Indonesia can be minimized.

This study aims to determine the effect of feeding fodder obtained from diversified dry land farming on daily weight gain, chest girth, shoulder height, and body length of male fattening Bali cattle. This study used a double Latin square design (LSD) with 4 treatments, namely T0 = local feed of farmers in Timor (farmer model). T1 = Diversified farm feed (T1 + mulato grass), T2 = T1 + legume Clitoria tarnatea, T3 = T2 + horticulture by-product using 4 periods as replicates. The livestock observed were eight male Bali cattle aged eight months to one year and weighed 97-121 kg (average 108.5 kg). The results showed that the feeding fodder obtained from the diversified farming had a significant effect (P<0.05) on daily body weight gain but not significant (P>0.05) on the linear body size measurements (chest girth, shoulder height, and body length). Considering the economical and convenient features, T2 feed treatment provided a greater contribution of 21.74% compared to control.

Published: May 2023

The oral examination is one of the traditional assessment methods which is considered to have low validity and reliability. However, several medical schools in Indonesia use structured oral examination as a part of the assessment systems, such as faculty of medicine Universitas Jenderal Soedirman. Structured oral examination is expected to have positive impact on student learning motivation. This research was conducted to explore students’ perception on the impact of structured oral examination on their learning. The research was a qualitative research with phenomenology approach. In-depth interviews were conducted with 5 students who were selected based on different gender and year of study. The results of this research indicated that students were motivated to learn better for structured oral examination since they had to face the examiner directly, they should understand the learning material in order to be able to do the examination and they must present the answers in a structured manner so that the examiner understood them. The issue of subjectivity became one of the triggers for students to study better. The methods used by students in preparing for structured oral examination were attending lectures and group discussions well, studying in groups and using audiovisual media to increase understanding. The negative impact of structured oral examination was the anxiety that arouse when students were about to take the examination. The large number of possible materials to be tested caused students to lose their focus on learning. Students realized that they should have good preparation to take the structured oral examination. Based on the results, it could be concluded that structured oral examination had a more positive impact than negative impact on student learning process.

A CASE REPORT: TRANSFORMATION OF ERYTHRODERMIC PSORIASIS TO CUTANEOUS T-CELL LYMPHOMA
Authors: Putranti Ismiralda Oke , Rahardjo Amelia B , Primanita Citra , Karsono Lilik , Widikusumo Arundito 
Published: May 2023

Background: Erythrodermic psoriasis (EP) is a severe type of psoriasis, a chronic inflammatory disease characterized by general erythematous condition with thick scale all around the body. The treatment of EP consists systemic medications like cyclosporine or methotrexate and biologic agents, which lately suggested related to the development of cutaneous T-cell lymphoma (CTCL) in severe psoriasis patients.
Case Report: A 45-year old, Javanese male was diagnosed previously with EP that transformed to CTCL. His previous history, he was histologically confirmed as psoriasis vulgaris since 2014 and was treated regularly with methotrexate. After 5 years, he gradually suffered several episodes of erythrodermic condition and was diagnosed with erythrodermic psoriasis with unusual pruritic hyperkeratotic plaques and ulcers on his trunks without any general lymph nodes enlargement. Peripheral blood smear showed Sezary cell and histopathology result confirmed CTCL. He was treated with combination of radiotherapy, phototherapy and topical regiments with a good result and acceptable.
Discussion: Several studies suggested that severe psoriasis had increased the susceptibility of CTCL, especially with the use of cyclosporine, methotrexate or biologic agents as the treatment. In this case, methotrexate might play role in the development of CTCL or enhanced the transformation of EP to CTCL. Combination of localized radiation therapy, NBUVB and topical therapy gave a quiet good result for the skin condition and increased patient’s quality of life.
Conclusion: Erythrodermic psoriasis might transform or develop to CTCL which in this case was probably related to the use of methotrexate.
