Determinasi Profitabilitas Perusahaan Perkebunan Kelapa Sawit yang Terdaftar di Bursa Efek Indonesia Tahun 2019 - 2024
Get PDFTopik khusus ini bertujuan untuk menganalis perputaran kas, perputaran piutang, perputaran persediaan, ukuran perusahaan, current ratio, struktur modal yang diproxi dengan debt to equity ratio (DER) dan pengaruh berbagai variable tersebut terhadap profitabilitas yang diproxi dengan return on asset (ROA) pada Perusahaan Sub-sektor Perkebunan Kelapa Sawit yang terdaftar di Bursa Efek Indonesia pada tahun 2019-2024. Teori yang digunakan didalam penelitian ini adalah teori profitabilitas, perputaran kas, perputaran piutang, perputaran persediaan, ukuran perusahaan, current ratio dan struktur modal. Penelitian-penelitian terdahulu dalam penelitian ini diperoleh dari jurnal-jurnal nasional dan internasional yang bereputasi sebagai pedoman untuk memperoleh research gap atau kebaharuan penelitian (novelty). Beberapa research gap yang didapati seperti perputaran kas, perputaran piutang, perputaran persediaan, ukuran perusahaan, current ratio dan struktur modal tidak berpengaruh terhadap profitabilitas perusahaan. Hal ini sejalan dengan phenomena gap bahwa industri perkebunan kelapa sawit merupakan industry non manufacture karena industri perkebunan kelapa sawit sangat tergantung kepada alam dan tanaman kelapa sawit mempunyai life cycle yang memerlukan peremajaan dimana dalam masa peremajaan perusahaan tidak menghasilkan produksi selama 3 tahun dan hal ini sangat mempengaruhi profitabilitas perusahaan. Topik khusus ini merupakan kelanjutan penelian S2 saya yang sebelumnya menggunakan 4 variabel independen yaitu perputaran kas, perputaran piutang, perputaran persediaan dan struktur modal dengan 1 variabel dependen yaitu profitabilitas (ROA) dan pada topik khusus ini untuk novelty penelitian (pembaharuannya) ditambahkan 2 variabel independen yaitu ukuran perusahaan dan current ratio sehingga menjadi 6 variabel independen. Novelty selanjutnya periode data pada topik khusus adalah 2019-2024 sementara periode data sebelumnya 2018-2023
Structural Analysis of Psycological Determinants in Driving Green Purchase Intention and Environmentally Conscious Behavior
Get PDFThis research investigates the relationships among Attitude Toward Behavior (ATB), Behavioral Intention (BI), Environmental Knowledge (EK), Purchase Intention (PI), and Perceived Consumer Effecti-veness (PCE) concerning Ecologically Conscious Consumer Behaviour (ECCB), focusing specifically on individuals aged 15–30 years. A quantitative research design was employed, using a convenience sam-pling method with 475 respondents. Data was collected via a structured survey and analyzed using SEM-PLS. The study assessed both direct and indirect effects to understand the mediating roles of BI and PI. The findings reveal that all tested direct and indirect paths are significant. ATB positively influences BI and PI. BI significantly affects ECCB and PI. EK shapes BI, ECCB, and PI. Finally, PI contributes to ECCB. Mediation analysis indicates that EK, PI, and BI serve as dominant mediators in both single and sequential mediation. This study strengthens the Theory of Planned Behavior (TPB) framework by empirically de-monstrating that positive ATB, EK, and PCE are crucial in shaping ethical consumption patterns among young people. The results highlight the pressing need to promote environmental awareness and empo-wer young consumers through focused educational initiatives and green marketing approaches that translate positive intentions into real sustainable practices
The influence of local economic development in poverty alleviation within Lepelle-Nkumpi Local Municipality, South Africa
Get PDFThe focus of this paper is to evaluate the influence of local economic development (LED) in poverty alleviation in municipalities using Lepelle-Nkumpi Local Municipality as a case paper. LED is essential as it involves identifying and using primarily local resources and skills to ensure or stimulate local economic growth and community development. Municipalities are responsible to ensure the promotion of LED initiatives to alleviate poverty. This paper was motivated by fact that there is lack of promotion of LED projects, high rate of poverty and unemployment and other socio-economic related issues that is occurring in communities within Lepelle-Nkumpi Local Municipality. Although the Municipality is continuing with the implementation of LED strategy but high rate of poverty and unemployment persist. Lack of capacity, incorrect interpretation or implementation of LED and resource constrains are some of the factors that contribute to failure of LED implementation in municipalities even though they are policies or guidelines in place. LED implementation in Lepelle-Nkumpi Local Municipality is constraints by many factors which hinder it to achieving economic development and poverty alleviation. The Municipality have challenges such as lack of budget, political interference in the allocation of LED projects, double dipping of projects, dependency syndrome of LED projects, LED strategies which do not address socio-economic challenges of communities, absence of monitoring and evaluation. Local economic development must contribute effectively on poverty alleviation and should have strong social focus
Accountability of Corruption Perpetrators Who Have Returned Money from Corruption Funds (Case Study of Case No. 49/Pid.Sus TPK/2021/PN Mdn)
Get PDFThis study aims to analyze the criminal responsibility of perpetrators of corruption who have returned state financial losses. Criminal responsibility in corruption crimes is regulated in Article 2 paragraph (1) and Article 3 of Law Number 31 of 1999 concerning the Eradication of Corruption. This study examines a corruption case with defendant Petrus Sabungan Hiras Fredy Aritonang Radjagukguk who was charged with committing a corruption crime with a state loss of Rp5,900,000,000, as decided in Decision Number 49/Pid.Sus-TPK/2021/PN Medan. In this case, the panel of judges at the first instance acquitted the defendant, even though the public prosecutor had filed a cassation appeal which was later rejected through Decision Number 2767 K/Pid.Sus/2022. The research method used is normative legal research with a statutory approach and case studies, which are sourced from primary and secondary legal materials through literature studies. This research is descriptive with qualitative data analysis. The results of the study indicate that the restitution of state financial losses does not eliminate the criminal liability of the perpetrator of corruption, but can only be used as a mitigating factor for the sentence, as stipulated in Article 4 of Law Number 31 of 1999. The court's decision in the a quo case is deemed not to fully reflect the spirit and objectives of eradicating corruption, because the judge's considerations have not optimally assessed the defendant's position, authority, and responsibility in the process of committing the unlawful act

Data Mining with Logistic Regression and Support Vector Machine for Hepatitis Disease Diagnosis
Get PDFHepatitis is a chronic and dangerous disease that can lead to death. Making early predictions to detect hepatitis is very important because many people still underestimate the disease. These predictions can be made by collecting patient data or health examination results, so that preventive measures can be taken faster and better. Early diagnosis of the disease is important for prompt management and treatment. The right stage of diagnosis activities and accurate disease prediction in time can save many patients. The magnitude of this disease problem in Indonesia can be known from various studies, studies, and disease observation activities. In this study, researchers will apply and compare data mining classification methods, namely the Logistic Regression method and Support Vector Machine to diagnose hepatitis disease. Based on the research, it is known that the Logistic Regression method has an accuracy rate of 84.62% and an under the curve (AUC) value of 0.841, then the Support Vector Machine method has an accuracy rate of 87% and an AUC value of 0.865. From the t-test results, it can be seen that there is no significant difference between the Logistic Regression and Support Vector Machine methods, because the value = 0.520>0.05. This shows that the Logistic Regression method has almost the same performance as the Support Vector Machine method. Hopefully the results of this research can help doctors determine a diagnosis more quickly and reduce the possibility of misdiagnosis so that early detection of hepatitis can be carried out more widely, especially in remote areas with limited health facilitie
