Performance of Ridge Regression, Least Absolute Shrinkage and Selection Operator, and Elastic Net in Overcoming Multicollinearity
Authors: Saputro Dewi Retno Sari , Wahyu Nugroho Lambang , Widyaningsih Yekti 
Published: February 2025

Multicollinearity is a violation of assumptions in multiple linear regression analysis that can occur if there is a high correlation between the independent variables. Likewise, the variants of multiple linear regression models such as the Geographically Weighted Regression model (GWR). Multicollinearity causes parameter estimation using the Quadratic Method (QM) unstable and produces a large variance. On the other hand, what is expected in the estimation parameters is an estimate with a minimum variance, even though it is biased. Thus, one way to overcome multicollinearity can be to use biased estimators, such as Ridge Regression (RR), Least Absolute Shrinkage and Selection Operator (LASSO), and Elastic Net (EN). In RR, the Least Square Method (LSM) coefficient is reduced to zero but it can’t select the independent variable. However, the parameter model obtained from the Ridge Regression is biased, and the variance of the resulting regression coefficients is relatively tiny. In addition, the RR is increasingly difficult to understand if a huge number of independent variables are used. Meanwhile, LASSO is a computational method that uses quadratic programming and can act out the RR principles and perform variable selection. The LASSO method became known after discovering the Least-Angle Regression (LARS) algorithm. The LASSO method can reduce the LSM coefficient to zero to perform variable selection. LASSO also has a weakness, so EN is used. In this article, the performance of the three methods is compared from the mathematical aspect. The performance of each is written as follows, RR is helpful for clustering effects, where collinear features can be selected together; LASSO is proper for feature selection when the dataset has features with poor predictive power and EN combines LASSO and RR, which has the potential to lead to simple and predictive models.

Purpose: The purpose of this study is to examine the effect of cashless policy on financial sector development in Nigeria specifically it sought to examine the effect of mobile banking automated teller machine and point on sale on financial sector development in Nigeria.
Methodology: The study adopted VAR methodology coupled with the the Philips-Perron test (PPT) to test the stationarity of the variables and ordinary least square (OLS) estimation technique to confirm the robustness of the model, error correction model (ECM) to determine the speed of adjustment, using annual time series data (secondary data) covering the period 2012-2022.
Findings: The findings revealed that there is positive relationship between ATM and financial sector development is as a result of e-transaction through technology acceptance and diffusion of innovation of cashless policy in Nigeria. The result also revealed that point of sale (POS) and mobile banking (MB) had an inverse and significant effect on financial sector development in Nigeria. This insignificant effect can be attributed to poor internet and power supply, inadequate supply of point-of-sale devices and unfriendly deposits money banks mobile applications of some banks in Nigeria. Mobile banking services, despite having an inverse relationship with financial sector development, reduce commercial bank queues due to their ease of use.
Unique Contribution to Theory, Practice and Policy: The study recommends that to promote cashless economy, massive sensitization campaigns and reliable power supply are necessary. Furthermore, the regulatory bodies must address issues such as faulty ATM machines, robbery, limited access and excessive charges.
Green Economy in South Sudan
Authors: Atem Paul Gal 
Published: February 2025

Purpose: The purpose of this study was to examine and contribute to the understanding of the complexities surrounding green economy concept in South Sudan. The study relied much on Malthus theory.
Methodology: The study used qualitative research methodology where an interview guide and focused group discussion were used to gather data which was then coded in themes. A sample of 150 respondents were selected using purposive sampling technique. These included the Members of Parliament, Technical staff from the Ministry of environment and forestry, local government and community members. Members of parliament were chosen because parliament’s role was to allocate funds to government projects and hence a political goodwill for green economy. The researcher further reviewed case studies and articles for a better understanding of the complexities of green economy.
Findings: Key findings showed that although the Ministry of Environment and Forestry had a policy on green economy there was no framework regulation for operationalization of the policy implementation. The study further found out that due to lack of regulations, there was no budget allocation for green economy hence, left to donors and NGOs.
Unique Contribution to Theory, Practice and Policy: The study therefore recommended for stringent regulations to be enhanced and budget allocations for green economy. The study further recommended for the involvement of private investment partners in green economy whose focus was on growing wealth that will support wellbeing. The wealth in this case is not merely financial but includes the full range of human, social, physical and natural capitals as it further promotes equitable distribution of opportunity outcomes, thus reduces disparities between people while giving sufficient space for wildlife and wilderness.

Pengabdian Masyarakat merupakan salah satu pilar Tri Dharma Perguruan Tinggi, disamping dharma pendidikan dan pengajaran serta dharma penelitian. Seperti kita ketahui bersama, pelaksanaan penyembelihan hewan qurban, merupakan kegiatan yang dimulai dari sebelum – proses dan pasca penyembelihan hewan qurban. Ketiga tahapan tersebut merupakan satu rangkaian yang harus dilaksanakan oleh lembaga / panitia yang mengadakan acara penyembelihan hewan qurban. Nah tahapan yang sering dilupakan atau dianggap tidak perlu adalah tahapan pasca pelaksanaan penyembelihan hewan qurban. Padahal pada tahap pasca yang berbentuk evaluasi.
Metode yang digunakan dalam kegiatan ini adalah metode ceramah dan metode praktek. Melalui metode ini guru-guru, masyarakat serta siswa/i langsung mendengarkan apa yang dimaksud dengan perhitungan daging sapi bersih oleh dosen dan bisa dibimbing langsung terkait dengan perhitungan rendemen sapi, hasilnya yaitu Setelah berat bersih sapi dan kambing dijumlah secara keseluruhan dan dikurangi permintaan sebesar 30 %. Hasilnya menjadi daging stok yang akan dibagikan kepada mereka yang berhak menerimanya Namun demikian panitia khususnya TIM MONITORING harus terus memantau perkembangan dan manakala ada yang tidak sesuai antara perhitungan dengan realisasi daging qurban, maka tim monitoring dapat koordinasi dengan bagian perhitungan untuk dilakukan langkah-langkah antisipasi dan mungkin juga perhitungan ulang

This study aims to develop a digital laboratory-based learning media called “Terra Academy Rock and Soil” (TARS) and evaluate its effectiveness on student activeness and learning outcomes. The research used the ADDIE (Analyze, Design, Development, Implementation, Evaluation) development model and was conducted at SMA Negeri 16 Surabaya involving 70 grade X students, divided into experimental and control classes. The use of the TARS digital laboratory in the experimental class resulted in an increase in the average learning outcomes from pretest (71) to posttest (76). Meanwhile, the control class only showed an increase from the average pretest (71) to posttest (72). Based on the results of the independent sample t test in the experimental class, the sig (2-tailed) value of 0.042 <0.05 was obtained, so it can be concluded that there is a significant difference between the average learning outcomes of students in the control and experimental groups, proving that TARS has a more positive impact on student learning outcomes. Although effective, this development has limitations, namely not supporting device types with the IOS operating system, so it needs to be developed further.

Rights and Obligations of Husbands to Wife According to Law No. 1 of 1974 Article 34 and Islamic Law
Authors: Fathoni M Insan , Wanti Siti 
Published: February 2025

The differences in the concepts of rights and responsibilities outlined in Article 34 of Law No. 1 of 1974 and Islamic law create challenges for Indonesian society, especially regarding the roles of husbands and wives within a marriage. This study aims to explore these rights and obligations, comparing how they are defined in both legal frameworks and identifying their similarities and differences. This research is a library-based study using a comparative approach to analyze both perspectives. The findings show that, at their core, both systems prioritize family well-being and harmony. Both emphasize a husband’s duty to provide financial support and protection for his wife. However, the key difference lies in how these responsibilities are implemented and the legal foundations behind them. Islamic law places a strong emphasis on a wife’s obedience to her husband in matters that align with religious and moral principles (ma’ruf), while the law provides more detailed guidelines on the husband's duty to treat his wife well, both physically and emotionally. Ultimately, the rights and responsibilities of a husband toward his wife, as outlined in Article 34 of Law No. 1 of 1974 and Islamic law, center around financial support, protection, and family leadership. To maintain a harmonious household, a husband must understand and fulfill these responsibilities fairly, in accordance with both legal and religious principles.

Published: February 2025

There are certain issues (mustajaddad) that cannot be found empirically from the texts, but the methodological framework is crystallized from the postulates which are qath'i as a form of Islamic law management method called Saddu Dzarî'ah. A mujtahid who initiated the istinbât methodological framework who is famous for his maqâshid is Imam Syafi'i (past a way 204 H). It is unique, when someone justifies that Imam Shafi'i does not recognize Saddu Dzarî'ah. The purpose of writing this thesis is to answer the real view of Imam Shafi'i regarding Saddu Dzarîah. This research belongs to the category of qualitative research based on document (text) studies that focus on Imam Syafi'i's views regarding Saddu Dzarî'ah in the process of finding Islamic law. The research process was carried out using the ushul fiqh and comparative fiqh approaches. The discussion in this study uses the document study method. After conducting an in-depth study and analysis of the book Al-Umm, it was found that Imam Shafi'i acknowledged Saddu Dzari'ah either as a proposition (mashadir Al-Ahkam) or as makharij fiqhiyah.
Issues of Peace and Security in Contemporary Nigeria

Published: February 2025

The issue of insecurity in contemporary Nigeria has become a threat to both internal and international peace and security with ever growing violence and attacks on security forces, civilians, churches, media houses as well as international bodies such as the United Nations. Consequently, we examine the complex issues that have affected the peace and security of contemporary Nigeria. This is done with the aim of finding solutions that can lead to success in fending off insurgency in contemporary Nigeria. Data used for this study was sourced from peace and security bulletin, books, newspapers and related journal articles on security issues. Using ordinary historical analysis, the result shows that the apparatus of peace and security earlier employed by the Nigerian state is inadequate. The findings of this paper identified the individuals as the centrepiece from where the household, community, the local government area, the state and the federation evolve and revolve as peace and security circles of different radii. It posited that peace and security concerns are in circles and actors within each circle are better attuned to concentrate and manage the peace and security challenge therein. This paper thus suggests the need for decentralization of the police and other state owned agencies of internal security management in order to mitigate the upsurge in crime and violence including those emanating from armed robbers, political assassins, ransom kidnappers, oil thieves, and Islamic insurgents among others.
