Economy of the Russian Federation for 2024–2025 and factors of its growth
Authors:   Financial University, Moscow, Russia, Tregub I.V.
Published: March 2024

The subject of the study is the influence of monetary and economic policies pursued by the Government of the Russian Federation on ensuring the economic stability of the country. The purpose of the work is to forecast real GDP growth due to the current wage policy, increasing household savings and supporting other demand factors based on correction and regression analysis, which makes it possible to find out between the characteristics under consideration and, if there is one, to calculate the measure of dependence using mathematical tools. To do this, it is proposed at the first stage to create an econometric model linking the growth of consumption and economic growth of the Russian Federation, at the second stage - to create and describe a model that allows us to consider the influence of the average nominal wage, the volume of lending to the population, the volume of savings and the level of inflation on the level of consumption in Russian Federation. The scientific novelty of the study lies in obtaining current data that allows us to identify the necessary level of the above factors to achieve the economic development planned by the Russian Ministry of Economic Development and growth of real GDP. As a result of the study, it was concluded that such a factor as the inflation rate is insignificant for analyzing the current economic situation in Russia. When developing effective measures to achieve the desired level of economic growth, according to the constructed model, the level of average nominal wages and the volume of household deposits are of greater importance. The effectiveness of the use of monetary measures used by the Bank of Russia to stabilize the economy has been confirmed.

Critical Review of Stack Ensemble Classifier for the Prediction of Young Adults’ Voting Patterns Based on Parents’ Political Affiliations
Authors: Elo Godwin , Ghansah Benjamin , Kwaku Kwaa-Aidoo Ephrem
Published: March 2024

Aim/Purpose: This review paper aims to unveil some underlying machine-learning classification algorithms used for political election predictions and how stack ensembles have been explored. Additionally, it examines the types of datasets available to researchers and presents the results they have achieved.

Background: Predicting the outcomes of presidential elections has always been a significant aspect of political systems in numerous countries. Analysts and researchers examining political elections rely on existing datasets from various sources, including tweets, Facebook posts, and so forth to forecast future elections. However, these data sources often struggle to establish a direct correlation between voters and their voting patterns, primarily due to the manual nature of the voting process. Numerous factors influence election outcomes, including ethnicity, voter incentives, and campaign messages. The voting patterns of successors in regions of countries remain uncertain, and the reasons behind such patterns remain ambiguous.

Methodology: The study examined a collection of articles obtained from Google Scholar, through search, focusing on the use of ensemble classifiers and machine learning classifiers and their application in predicting political elections through machine learning algorithms. Some specific keywords for the search include “ensemble classifier,” “political election prediction,” and “machine learning”, “stack ensemble”.

Contribution: The study provides a broad and deep review of political election predictions through the use of machine learning algorithms and summarizes the major source of the dataset in the said analysis.

Findings: Single classifiers have featured greatly in political election predictions, though ensemble classifiers have been used and have proven potent use in the said field is rather low.

Recommendation for Researchers: The efficacy of stack classification algorithms can play a significant role in machine learning classification when modelled tactfully and is efficient in handling labelled datasets. however, runtime becomes a hindrance when the dataset grows larger with the increased number of base classifiers forming the stack.

Future Research: There is the need to ensure a more comprehensive analysis, alternative data sources rather than depending largely on tweets, and explore ensemble machine learning classifiers in predicting political elections. Also, ensemble classification algorithms have indeed demonstrated superior performance when carefully chosen and combined.
Problematics of Inter-Regional Cooperation in Indonesia
Authors: Fauzan Muhammad , Indiahono Dwiyanto , Ardhanariswari Riris
Published: March 2024

This article aims to identify the problems of implementing inter-regional cooperation from the widest possible autonomy perspective. This becomes important because cooperation between regions seems to run well shortly after policies in the form of laws and government regulations are enacted. However, in regional cooperation, many problems lurk and can lead to the failure of cooperation between regions. This research is legal research using a statute approach, a conceptual approach, and a historical approach. This research method and approach are appropriate to explain the problematic phenomenon of cooperation between regions in Indonesia based on Law No. 23 of 2014 concerning Regional Government. Based on the results of preliminary research, several problems arise in the implementation of regional cooperation, especially cooperation between regions, including the following: First, cooperation between regions whose object is related to income sharing often experiences difficulties in its implementation, especially in determining the amount of income/profits for each region; Second, the emergence of regional egoism, especially in the cooperation between the Parent Region and the regions resulting from the expansion; Third, the lack of data and information about the object of cooperation that has the potential to be better if implemented through cooperation between regions that are geographically close together; Fourth, the lack of initiation to carry out cooperation between regions due to the mindset of each region to deal with internal affairs only; and Fifth, no institution/agency specifically handles inter-regional cooperation.
Why Did the Adoption of Constitutional Deferral Lead to Unintended Consequences of Freedom of Association in Indonesia?
Authors: Omara Andy , Viri Kristina , Rahman Faiz
Published: March 2024

A constitutional deferral is an approach utilised by constitutional drafters so that the drafters do not regulate things in detail in the constitution. This approach is believed to provide more opportunity for the constitutional framers to achieve consensus in drafting a constitution. In the end, this helps a constitution last longer. Constitutional deferral also offers some flexibility for the legislative and the judiciary in interpreting the text of the constitution in the future, which may accommodate the original intentions of the constitutional drafters. This paper argues the opposite. In Indonesia, adopting constitutional deferral causes an uncertain future of freedom of association. This paper aims to address two central questions. First, why did the framers of the first constitution adopt constitutional deferral in drafting provisions on freedom of association? Second, what are the consequences of implementing constitutional deferral toward freedom of association in Indonesia? Through historical and doctrinal approaches, the paper concludes (1) that the sharp ideological differences among constitutional drafters when drafting provisions on freedom of association forced them to employ constitutional deferral. (2) The use of constitutional deferral opens more possibilities for inconsistent interpretation by the executive, the lawmakers, and the judiciary when they establish law or adjudicated cases related to freedom of association. Through constitutional deferral, these three branches of government limit freedom of association instead of protecting such freedom.
Criminal Legal Protection for Bona Fide Third Parties Over Assets in Corruption and Money Laundering Cases
Authors: Patramijaya Arief
Published: March 2024

Criminal law in Indonesia has yet to guarantee justice and human rights of bona fide (good faith) third parties in protecting their confiscated assets in corruption and money laundering cases. Criminal procedural law is inadequate in providing assessments for bona fide third parties. Therefore, Economics and Anthropology are needed in the investigation stage up to the evidentiary stage during trials. In this research, the main problems are formulated as follows: (1) what is the concept, definition, and scope of the assets of third parties in good faith in the laws and regulations in Indonesia? (2) how is the application of legal provisions regarding the protection of third parties with good intentions in corruption and money laundering? (3) what is the ideal role of the Public Prosecutor and Judge in protecting the property of a third party with good intentions in the criminal justice system? Normative law research conducted in this article showed that (1) the concept and understanding of bona fide third parties in civil law can be adopted in criminal law; (2) the application of legal protection to bona fide third parties over their assets in corruption and money laundering cases still depends on the moral goodness of law enforcement officials; and (3) investigators, prosecutors, and judges play an important role in protecting the human rights of bona fide third parties in corruption and money laundering cases.

Published: March 2024

The era of free trade, including trade in labour services, has been confirmed in the General Agreement on Trade in Services, which guarantees everyone the right to work anywhere, including in Indonesia, without discrimination while complying with Indonesian national laws. However, the entry of foreign workers raises several problems in the social and economic fields as well as security and order regarding the placement of these foreign workers. Regulation over the workers is ineffective because only a few authorities are delegated to the local government. This study aims to determine and measure the effectiveness of supervision of foreign workers by the Department of Manpower and Transmigration of the Central Sulawesi Province and to describe the supervision standards of foreign workers that already exist and should be implemented. The empirical legal research is used to examine the provisions of the supervision of foreign workers through observation, in-depth interviews, and focus group discussions. The data that have been collected are processed, classified, qualified, and then analysed qualitatively. The study found that only a few authorities regulated the duties and functions of supervision. The standard of foreign worker supervision has yet to be specifically regulated, so it still faces obstacles regarding coordination between the authorised agencies.

Published: March 2024

Law No. 11/2006 on the Government of Aceh (Aceh Government Law) has mandated Aceh Qanun No. 11/2018 on ShariaFinancial Institutions. A thorough and integrated regulatory infrastructure must support the Qanun on Sharia Financial Institutions. The Qanun on Sharia Financial Institutions regulates that all Sharia Financial Institutions operating in Aceh must transition from the conventional to the Sharia system. However, in reality, many norms still need to be synchronised with national rules so that Sharia Financial Institutions do not run optimally. This study aims to map and harmonise legal issues and purification of Qanun on Sharia Financial Institutions in the future. The method used is normative juridical with a qualitative approach and uses secondary data. The study found that first, the mapping of Qanun on Sharia Financial Institutions still has articles that overlap and need to be more technical with the inclusion of the year that has passed. In addition, an article includes administrative sanctions that are not implemented. Then, there are ambiguous norms that cause multiple interpretations. Second, Qanun on Sharia Financial Institutions needs harmonisation with higher laws and regulations. In addition, several Governor and Regent Regulations and other technical rules are required to maximise the implementation. Third, purification is needed by revising articles that overlap with the rules above and harmonising them with national regulations in Islamic finance.

Published: March 2024

This research aimed to analyse where the legal politics concerning outsourcing in Indonesia's legal system by scrutinizing its regulation in Book III of the Civil Code and enforcement of the Government Regulation in lieu of Law concerning Job Creation Law Number 6/2023, with its following implication to protect workers at the national level. This research employed doctrinal legal research on legal instruments related to outsourcing with statutory, conceptual, and historical approaches. The research showed that legal politics concerning outsourcing had experienced dynamic congruence with the political configuration when the legislative product on outsourcing was made. The differences emerge where outsourcing is not restricted to certain occupations in Book III of the Civil Code of Indonesia. However, Law Number 13/2003 restricted the definition of outsourcing to occupations not related to core businesses. Law Number 11/2020 and Government Regulation Number 35/2021 fit employers. Both laws govern the legal protection for outsourced employees with the transfer of undertaking to protect employment regarding changing vendors with the condition that the jobs are still available. Meanwhile, the type of work outsourced is unlimited, resulting in a deficit compared to the previous norm.

Published: March 2024

This article explores the limitations of using physical force in educating children in Indonesia. It examines the prevalence of violence by parents and teachers in education. Increased public awareness and concern for children's rights have made the use of violence in education a taboo. This research uses a qualitative method with secondary data using literature and analysing court decisions from the human rights perspective. This study aims to determine the limits of tolerance for violence and corporal punishment. The court decisions have been taken as the data to be analysed from various locations where decisions have been issued were taken into consideration to depict the similarities and differences in deciding matters related to corporal punishment towards children. This article examines historical, cultural, and religious factors that influence the use of physical force, including interpretations of Islamic teachings. This paper also presents arguments for and against corporal punishment as an educational tool. This research sheds light on the complexities surrounding the permissibility of physical force in children's education and the conflicting views in society, providing insight into evolving understandings and legal perspectives on the subject.

Published: March 2024

The purpose of this study is to analyse the act of genocide in the attempt at Judaization in Palestine based on the 1998 Rome Statute and examine the possibility of categorizing the Judaization of Palestine as cultural genocide because Judaization has changed various aspects of Palestinian life and the Palestinian territories themselves. In addition, cultural genocide has been eliminated from its history, but there are still actions that are assumed to lead to it. This research is a type of normative legal research using a conceptual, statutory, case, and historical approach. The results of this study indicate that the Judaization of land and people in Palestine is a crime of genocide, as stated in Article 6 (c) of the 1998 Rome Statute. At the same time, the Judaization of identity and holy places can be categorized as cultural genocide, according to experts. However, the opinions of experts contained in legal works are subsidiary legal sources and, until now, have not been recognized as customary international law. In addition, the Judaization of identity and holy places within the framework of international law can only be viewed as genocidal intent, not cultural genocide.
Does the Reform of the Parliamentary and Presidential Threshold Strengthen the Presidential System in Indonesia?
Authors: Rannie Mahesa , Saraswati Retno , Wisnaeni Fifiana
Published: March 2024

The attempt to purify Indonesia's multiparty presidential system was only reflected after the Third Amendment to the 1945 Constitution. However, it took work to implement it. In practice. Various measures have been taken, including party alliances and introducing voting barriers in parliamentary elections. Therefore, analysing the relationship between electoral thresholds and their ideal proportions in the form of legal-political reforms to strengthen the Indonesian presidential system is interesting. This is in line with the purpose of this study, which is to uncover and analyse the legal politics of electoral thresholds in an attempt to strengthen the presidential system of government in Indonesia. The approach adopted in this study is a theoretical approach with legal, conceptual, comparative and historical approaches. This study concludes that the legitimate political renewal of the electoral vote threshold is not closely related to efforts to strengthen Indonesia's system of multiparty presidential government. The ideal way to reform the legal, political threshold for electoral votes would be to set the parliamentary threshold at 2.5%, but at the same time tighten controls over the parties participating in the election, and the 2.5% threshold serves as President to maintain a balance between the parliamentary and presidential thresholds. In addition, it is also important to strengthen consensus (consensus democracy) among coalition political parties. There is still a desire to abolish the presidential threshold through the People's Representative Council (DPR) instead of the Constitutional Court (MK).
Legal Consequences of Disobedience of Provisional Decision of the Administrative Court
Authors: Winarsi Sri
Published: March 2024

The existence of a legal vacuum in the State Administrative Court (PTUN) procedural law relating to the execution of the PTUN Provisional Decision raises the issue of Judicial Disobedience by state administrative institutions that do not want to carry out the PTUN Provisional Decision. Departing from this, there are two main problem formulations, namely: (1) What are the characteristics of PTUN provisional decisions? and (2) What is the formulation of legal protection against non-compliance with PTUN provisional decisions? Furthermore, this legal research uses a statutory approach, a conceptual approach, and a case approach. Based on an examination of existing legal issues, it can be concluded that provisional decisions are known in PTUN procedural law practice, where provisional decisions are submitted for matters deemed essential (urgent circumstances) by the Plaintiff to the Panel of Judges to be decided in an Interim Decision. Suppose the Party ordered by the PTUN does not implement the PTUN provisional decision. In that case, 2 (two) legal preventive mechanisms and 3 (three) legal repressive remedies can be taken in stages: 1) Sending a letter to the relevant agency, 2) Reporting to the Ombudsman, and 3) Using Criminal Law Mechanisms.

Authors: Mardones Rodolfo E. , Zunino Hugo M.
Published: March 2024

Este artículo está dirigido a caracterizar el discurso de comunidades intencionales. Para cumplir con este objetivo, implementamos un enfoque cualitativo basado en estudios de casos para describir y contrastar el fenómeno de las comunidades intencionales utópicas que tienen lugar en Chile. A través del análisis del discurso, describimos tres iniciativas en torno a los ejes: visión de sí mismos, visión sobre la sociedad, y prácticas dirigidas a crear formas ideales de existencia en común. Nuestros hallazgos muestran que los discursos articulan el conocimiento disciplinario y las prácticas con puntos de vista tradicionales y espirituales. Reconocemos las transformaciones sociales centradas en el cambio personal y el papel desempeñado por la comunicación mediada por Internet, para revelar disputas entre iniciativas comunitarias que sugieren alternativas a lo que es la norma en el contexto social neoliberal de Chile, promoviendo formas de reinvención del individuo, la comunidad y la relación con la naturaleza.

Authors: Fadun Olajide Solomon , Aduloju Sunday Adekunle , Ukpong Mfon Sampson
Published: March 2024

This study was conducted to assess fire risk transfer and its impact on the Nigerian economy over the period 1999 to 2019. It was borne out of the incessant fire outbreaks in the country in recent times which has led to an increase in fire risk premiums in the Nigerian insurance industry. The specific objectives were to investigate the trend of fire risk premium and real gross domestic product (RGDP) and assess the impact of fire risk premium on RGDP in Nigeria. The ex-post facto research design was adopted and the population consisted of all insurance companies covering fire risk as of 2019. Data were sourced from Nigeria Insurance Digest, the Central Bank of Nigeria statistical bulletin and the National Bureau of Statistics covering the selected years. The dependent variable for the study was RGDP while fire risk premium, exchange rate and money supply were independent variables. The trend analysis revealed that fire risk premiums increased at a faster rate than RGDP. while the regression analysis indicated a positive significant relationship between fire risk premiums and RGDP, and negative relationships between exchange rate and RGDP, as well as between money supply and RGDP. It was recommended that fire risk transfer should be encouraged for individuals and organizations to enhance its continued contribution to economic growth.
The Macroeconomic Effect of Oil Sector Crisis in Libya
Authors: Ben-Taher Hasen A.
Published: March 2024

This paper analyses and investigates the impact of the oil sector crisis on the Libyan economy from 2012 Q4 to 2022 Q3, using the Bai-Perron model and a structural vector autoregressive model (SVAR). The findings demonstrate that the multiple structural breaks test statistics approved that nearly all of the study's variables had a structural break at years around political division and political agreement. In contrast to inflation, the results of the impulse response functions (IRFs) indicate that the shock to oil revenue had a considerable negative impact on the money supply and exchange rate. Furthermore, the study reveals that, with the exception of claims on the government with the central bank, shocks to oil revenue are the major contributors to variance decomposition for all variables. The results reveal that oil revenue, in particular, accounts for roughly 16%, 13%, and 16% of the variance decomposition of the money supply, exchange rate, and inflation rate, respectively. As a result, the oil sector crisis is a controlling factor in the explanation of variations in these variables. The study concluded that oil sector revenues have a sensitive impact on the Libyan economy and that the latter has a strong tide with a secure environment and political stability.
Impoverishing effects of catastrophic health out-of-pocket payments in Nigeria
Authors: Opeloyeru Olaide Sekinat
Published: March 2024

Out-of-Pocket (OOP) expenditure on healthcare is a major share of total healthcare expenditure in many developing countries, including Nigeria. Households in different income groups in Nigeria spent a larger share of income mainly on consumption and basic needs, hence, OOP expenditure for health constituted a burden with attendant effects on household well-being. Catastrophic headcount and Overshoot mean positive gap and concentration indexes were used to capture the incidence and severity of catastrophic health expenditure. The poverty headcount, poverty gap, normalized poverty gap, and its mean estimate were used to empirically identify the effect of catastrophic health expenditure using the national poverty line of ₦137,430 per year. Data on 22,110 households with non-zero expenditure were obtained from the 2018/2019 Nigeria Living Standard Survey. The incidence and severity of catastrophic health expenditure were higher for poorest and poor income quintiles using total consumption expenditure and total non-food expenditure at various catastrophic thresholds. The results indicated that about one million Nigerians were pushed into poverty due to OOP expenditure. Widening the coverage of the available social health insurance and implementation of alternative means of healthcare financing would minimize the financial burden on many poorest and poor households.
Informal Learning at workplace in the Middle East: Exploring the role of informal learning levels on Team Performance in Qatar
Authors: Al-Hajri Dana
Published: March 2024

In organisations, informal learning is recognised as one of the major contributors towards learning and development for employees. Over the years, researchers and practitioners continually attempt to understand the relationship between informal learning and team performance, yet this relationship is highlighted to be complex to assert. This study aims to explore the role of different informal learning levels (self-reflection (individual), managerial coaching (dyadic), and knowledge exchange (team)) on team performance in Qatar. Data collection was conducted using quantitative method through deploying the use of questionnaire survey with 47 teams within a selected company in Qatar. The findings showed that understanding the relationship between informal learning and team performance is complex, but using activities at different levels provided a holistic, yet more assertive approach to further understand that relationship. The study found that the team knowledge sharing have the highest values among the informal learning activities while managerial coaching were less practiced. On the one hand, the results derived from the regression tests showed that there is no strong association between informal learning and team performance which indicates that complex relationship between those two variables and how informal learning activities are motivated/demotivated in organisations. The study concluded by proposing an abstract conceptualisation to understand the relationship between informal learning and team performance.

Authors: Mirawati Dian , Karyadi L. Wiresapta , Hayati Hayati
Published: March 2024

The dynamism of farmer groups is influenced by internal factors, namely the farmer group itself, and external factors, namely the role of the Agriculture Extension Worker (AEW). This research was carried out in West Lombok Regency with the criteria of selecting 2 sub-districts in West Lombok Regency which had a larger dry land area compared to other sub-districts, namely Sekotong District and Lembar District; from each sub-district 3, villages were selected with the criteria of having the largest number of farmers, determining selected farmer groups based on criteria. Farmer groups have been registered in the Decree of the Head of the West Lombok Regency Agricultural Service and have been recorded in the agricultural extension system (simluhtan). This research aimed to analyze the role of AEW, the dynamics of farmer groups, and the influence of the role of Agriculture Extension Worker (AEW) on the dynamics of farmer groups in dryland farming areas in West Lombok Regency. The analytical method used was descriptive analysis with a Likert scale by giving a score of 1-5 for each criterion for each indicator. The research results showed that the respondents' assessment of the role of field agricultural instructors as facilitators, educators, motivators, and organizers was in a good category. Farming group dynamics seen from the aspects of group goals, group structure, task functions, group coaching and development, group cohesiveness, group atmosphere, and group effectiveness was in the quite good category, and the relationship/correlation between the role of AEW and the dynamics of farmer groups was very strong.

Authors: Wasie Tilaye Anbes , Shibie Belayneh
Published: March 2024

Field experiments were conducted to identify seed rate enhancing seed multiplication ratio, seed quality and yield on Ibone (174/03) malt barely variety performance in Koga district during 2019 and 2020 irrigation seasons. Three seed classes (breeder, pre-basic and basic seeds) and seed rates (40, 60, 80 and 100 kg.ha-1) were compared. The experimental design randomized complete block in factorial arrangement with three replications. Analysis of variance was showed that the interaction effect of seed class and seed rate was not significant (P>0.05) for the parameters of days to maturity, plant height, spike length, seed yield, seed multiplication ratio and thousand seed weight. The study result depicted that seed rate had brought significant effect on the seed yield and multiplication ratio of malt barely. Results indicated that lower seed rates gave better seed multiplication ratio in the districts. Increasing seed rate from 40 to 80 kg.ha-1 has increased seed yield from 3356.1 kg.ha-1 to 3696.8 kg ha-1 though seed yield difference between seed rates of 60 and 80 kg.ha-1 was statistically non-significant (p>0.05). Increasing seed rate from 40 to 60 kg.ha-1 has continuously improved seed yield from 3356.1 to 3592.1 kg.ha-1 in all seed class in the districts, but the difference was statistically non-significant. In conclusion, seed rates as low as 60 kg.ha-1 can be used at all seed classes to accelerate early generation seed multiplication within the fast track variety release program in Western Amhara Region.

Authors: Madushani Manawaduge Ayesha , Sirisena Anura Indrajith
Published: March 2024

The current whitefly invasion is becoming a growing threat to coconut palms in Sri Lanka and will severely influence coconut production in the country. To effectively manage this problem, it is crucial toidentify the specific species that have invaded the coconut palms in the country to accordingly provide appropriate solutions. The taxonomy of the whitefly is mainly based on the characters of the pupae. Thus, a field survey was conducted in 2023 to identify the key whitefly species that invaded the coconut palms and their host range in Sri Lanka. The colonies of infested whiteflies were collected from coconut palms in different coconut-growing areas of Sri Lanka, and the pupae were slide-mounted and identified up to species level using taxonomic keys. Further, diagnostic characters of each species and host range were documented. The whitefly species found on the coconut palms (Cocos nucifera) were identified as Aleurodicus rugioperculatus, Aleurodicus dispersus, and Aleurotrachelus atratus. A. atratus was discovered only from the C. nucifera. A. dispersus and A. rugioperculatus were reported from 5 and 24 host plant species including the coconut from 5 and 18 different families respectively.

Authors: Susanti Lea , Suketi Ketty , Kurniawati Ani , Setyadjit
Published: March 2024

Salak, or snake fruit, is a tropical fruit with a short shelf life when stored at room temperatures. The fruit’s base, if injured or bruised, can serve as an entry point for microbes, leading to physical and chemical damage to the fruits. This research aims to determine if chitosan and 1-methylcyclopropene (1-MCP) treatment can prolong the shelf life of salak “Pondoh”. The study tested two factors, chitosan (0%, 0.5%, 1.0%, 1.5%) and 1-MCP concentrations (0, 0.5, 1.0, 1.5 µL.L-1). The findings indicate that the application of chitosan and 1-MCP treatments did not significantly extend the shelf life of the fruits on the 15th day of observation. However, 1.0% chitosan combined with 1.5 µL.L-1 1-MCP and 1.5% chitosan combined with 0.5 µL.L-1 1-MCP proved effective in enhancing the fruit’s overall quality and maintained low ethylene production, high water content, and enhanced the organoleptic attributes including ease of peeling, fruit flesh color, texture, aroma, and taste.

Authors: Indriani Yulia , Aziz Sandra Arifin , Melati Maya
Published: March 2024

Indian camphorweed (Pluchea indica Less.) leaves exhibit antioxidant, antibacterial, anti-inflammatory, and antimicrobial activities, indicating significant potential for the pharmaceutical industry. This research aimed to determine the optimal rates of chicken manure for enhancing leaf and total flavonoid production in Pluchea indica. The study took place at the IPB Experimental Station in Bogor, Indonesia,spanning from July to October 2023. A completely randomized block design with a single factor (chicken manure doses) was employed: 0, 2.5, 5, or 7.5 kg per plant. Each treatment comprised three replications, each consisting of 20 plants. The results revealed that the application of chicken manure at 2.5 kg per plant led to significantly taller plants, more leaves, and tertiary branches compared to the control group. Specifically, the 2.5 kg dosage significantly increased the nitrogen content of the 7th leaf and the potassium content of the 3rd leaf. Meanwhile, the application of 5 kg of chicken manure per plant significantly boosted phosphorus content in the 3rd and 7th leaves and potassium content in the 5th and 7th leaves. However, no significant differences were observed in total flavonoid and antioxidant activity across all leaf positions with chicken manure application. Plants receiving 5 kg of manure demonstrated the highest fresh leaf weight (81.64 g) and dry weight (38.27 g), which were significantly greater than those receiving 2.5 kg per plant or no manure. Despite these variations, flavonoid production per plant did not show a significant difference with manure application.

Published: March 2024

Identification of post-harvest physiological deterioration (PPD) tolerance in cassava is crucial, as PPD significantly hampers the cassava tuberous root industry by shortening storage periods post-harvest and diminishing product quality. Characteristics linked to PPD tolerance encompass high carotenoid levels and low dry matter content (DMC). This study aimed to evaluate the PPD responses of six yellow fleshed and ten white-fleshed cassava tuberous roots and determine the source of PPD tolerance. PPD and DMC assessments were conducted using standard methods at three storage periods: 2, 5, and 10 days after harvest (DAH). The k-means clustering analysis revealed six clusters, each corresponding to distinct PPD symptom patterns and tolerance statuses. Cluster 1, comprising three yellow-fleshed and three white-fleshed cassava cultivars, demonstrated PPD tolerance with minimal symptoms up to 5 DAH. Clusters 2 and 3 exhibited a moderate PPD response with elevated symptoms at 5 DAH, comprising three yellow-fleshed and three white-fleshed cassava cultivars. Clusters 4 to 6 displayed a sensitive response to PPD, showcasing a significant increase in symptoms at 5 and 10 DAH, with four white-fleshed cassava cultivars identified within this cluster. These findings underscored the presence of PPD tolerance in both yellow-fleshed and white-fleshed cassava tuberous roots. The correlation between PPD and DMC was significant only at 2 DAH, displaying a moderate positive correlation. Consequently, this study identified three cultivars, “Carvita-25”, “Manggu”, and ““Ubi Kuning””, with high DMC and low PPD incidence at 5 DAH, suggesting their suitability for further breeding programs.

Edible coating is a barrier, thin layer of consumable material to maintain moisture and slow down the respiration process of a product. In order to preserve the quality of red chili, this study aims to find the ideal taro starch concentration to use as an edible covering. Six treatments of taro starch concentration—0, 1, 2, 3, 4, and 5%—were used in experimental research utilizing a completely randomized design (CRD). Hedonic organoleptic testing produced the data. Analysis of variance (ANOVA) is then performed based on the level of panelist preference, and an LSD test is applied if there is a significant difference. The findings indicated that a 5% concentration of taro starch works best as an edible covering material to preserve the quality of red chili

The newest Curriculum stipulates a scientific approach as a characteristic of the national PAUD curriculum. In reality, kindergartens still have not optimized this. Therefore, it is necessary to identify the science process skills of early childhood students so that improvements can be made immediately. This research aims to identify and analyze the science process skills of Group B Students at Kreativa Gebang Kindergarten. This is descriptive research. The research instruments used were video recordings of learning activities, observation sheets for learning activities, and student development assessment reports (LPPA). The data obtained in this research was analyzed using a combination of analysis (quantitative – and qualitative). The results showed: 1) The identified science process skills of Group B students were observing, classifying, and communicating skills; 2) The percentage of achievements in observing skills that were categorized into developing very well (BSB) categories were 41.4%, Classification skills were at 32.8%, and communication skills were at 14%. Based on the data, it can be concluded that the science process skills of group B students at PAUD Kreativa Gebang were still relatively low because the percentage of achievements in the three science process skills that were categorized into developing very well (BSB) categories was below 50%.

Differentiated learning is important in the world of education, because of the diversity of students’ learning methods and students’ different knowledge backgrounds. The aim of this research is that differentiated learning in chemistry material and the teaching and learning process can run effectively and efficiently. Differentiated learning can eliminate students’ fear of material they don’t like, especially chemistry. This research is qualitative research, to see the effectiveness of differentiated learning, the CIPP research model is used. This CIPP model includes context, input, process and product, so it is said to be more comprehensive than other evaluation models. The research data sources are Chemistry Teachers, curriculum representatives, and students at three high schools in Jakarta. Primary data was collected using observation instruments while secondary data was obtained through questionnaires and interviews. The research results show that what happens in the field is that not all teachers apply differentiated learning during the teaching and learning process in the classroom. Through differentiated learning, students tend to be more active and enthusiastic about learning because classroom learning is carried out according to each student’s interests, readiness, and learning style. So, learning activities with a differentiation system are stated to be quite effective
