Abstract

This research aims to examine the effect of managerial ability and capital structure on firm performance and firm value, with firm size and firm growth as control variable. Research samples were manufacturing  companies   listed on Indonesia Stock Exchange (IDX)  at 2011, 2012, and  2013. This research used Data Envelopment Analysis (DEA) to measure managerial ability, and capital structure were measured by DER. The results of this research showed that more skilled  manager will inrease firm performance as measured by ROA and firm value as measured by share price. Another result shows that higher rate of DER will decrease firm performance as measured by ROA and firm value as measured by share price. Control variable firm size is proved to have significant positive effect on ROA and share price. Firm growth has significant positive effect on ROA, but has no effect on share price.Keywords: Managerial Ability, Capital Structure, Data Envelopment Analysis, Firm Performance, Firm Value, Firm Size, Firm Growth.

Abstract

Based on simulation data from recapitulation of Health Facilities waste or medical B3 waste in Tegal City in 2022, it was recorded as 454 kg of medical B3 waste per day. Recap of data for Health Facilities in areas around Tegal City (Slawi, Brebes, Pekalongan, Pemalang and Batang) recorded 3,336 kg of B3 medical waste per day. This condition has the potential to cause environmental problems if not addressed. This research aims to provide an analysis of the feasibility of investment for handling medical waste. The study used secondary data sourced from the Tegal District Government Health Service and primary data collected through field observations. The research results show that the condition is suitable to continue. Investment funds required are IDR. 28 billion more. The financial feasibility results show an Internal Rate of Return (IRR) using a discount rate of 7.042%. Net Present Value (NPV), for considering the time value of money of 7.042% produces a positive value. The Investment Payback Period does not exceed the loan term. The feasibility results from economic and social environmental aspects also show that this waste management investment can be recommended for regional government implementation.

Abstract

This reseach purposed to investigate the influence of price and product quality, both partially and simultaneously, on purchasing decisions at the Telorindo Store, South Tangerang. The method used is quantitative. The sampling technique used the Slovin formula, with a sample size of 95 respondents. Data were collected using questionnaires, and data analysis techniques using validity, reliability, classical assumption tests, simple regression analysis, multiple regression multiple regression, hypothesis testing, t test, f test, and coefficient of determination. The results of this research show that partially price has a significant effect on purchasing decisions. This can be proven that tcount > ttable (5,110 > 1,987). From the results of simple linear regression analysis, the regression equation Y = 25,863 +0.516Χ1 The regression coefficient value obtained was 0.468, where the value was in the interval 0.400 – 0.599, meaning that the two variables had a moderate level of relationship And product quality has a significant influence on purchasing decisions. This can be proven by tcount>ttable (6,778 > 1,987). And the regression equation value Y = 18,924+ 0.567 This means that the two variables have a moderate level of relationship. Meanwhile, simultaneously price and product quality have a significant effect on purchasing decisions with the regression equation Y = 17,221 + 0.182X1 + 0.462X2, showing a (positive) influence. And the results of the hypothesis test obtained a value of f count > f table (24.382 > 3.10), while the results of the coefficient of determination were 0.346 or 34.6%. It can be concluded that the Price and Product Quality variables have a significant effect on the decision variable. Meanwhile, the remaining 65.4% was influenced by other factors that were not carried out by researchers.

Abstract

Kemiskinan masih menjadi masalah kompleks di berbagai daerah termasuk Sumatera Selatan. Garis kemiskinan diprediksi menggunakan metode interpolasi Newton-Gregory berdasarkan data historis dari Badan Pusat Statistik (BPS) dari tahun 2022–2024. Metode ini dipilih karena mudah digunakan dan mampu memberikan data yang akurat. Penelitian ini menggunakan bahasa pemrograman Python, yang membantu pengolahan data menjadi lebih efisien. Hasil penelitian menunjukkan bahwa metode ini memberikan prediksi yang sangat akurat dengan nilai Mean Absolute Percentage Error (MAPE) sebesar 2,81%. Berdasarkan hasil prediksi menunjukkan bahwa garis kemiskinan di sebagian besar wilayah akan meningkat pada tahun 2024 dan 2025. Ogan Komering Ulu Selatan memiliki garis kemiskinan terendah, sedangkan Kota Palembang memiliki garis kemiskinan tertinggi. Diharapkan penelitian ini bisa menjadi alternatif untuk membantu perencanaan pembangunan berbasis data yang lebih baik.Keywords: Proverty, Newton-Gregory Interpolation, South Sumatera, Prediction, MAPE

Abstract

Penelitian ini menganalisis pengaruh Earning Per Share (EPS) dan Return on Equity (ROE) terhadap harga saham empat bank umum syariah yang terdaftar di Bursa Efek Indonesia (BRIS, BTPS, BANK, PNBS) selama tahun 2019-2023 dengan menggunakan metode kuantitatif asosiatif dan model regresi data panel fixed effect (FEM). Hasil regresi menunjukkan bahwa EPS berpengaruh negatif dan signifikan terhadap harga saham, sedangkan return on equity (ROE) berpengaruh positif dan signifikan terhadap harga saham. Hasil uji F menunjukkan bahwa EPS dan ROE secara simultan berpengaruh terhadap harga saham. Peningkatan ROE mendukung peningkatan harga saham, oleh karena itu, investor harus lebih memperhatikan ROE. Selain itu, manajemen bank perlu meningkatkan efisiensi modal, dan memasukkan variabel tambahan dalam penelitian selanjutnya untuk analisis yang lebih komprehensif.

Abstract

Diabetes merupakan penyakit kronis yang sering terlambat terdiagnosis akibat gejala awal yang tidak spesifik, sehingga deteksi dini penting untuk mencegah komplikasi serius. Penelitian ini bertujuan menganalisis dan membandingkan performa kombinasi Principal Component Analysis dengan K-Nearest Neighbor (PCA-KNN) dan Support Vector Machine (SVM) dalam prediksi risiko diabetes. Dataset yang digunakan berasal dari Kaggle dengan 768 entri dan delapan atribut medis. Tahap praproses mencakup imputasi median untuk nilai nol, normalisasi Z-score, serta reduksi dimensi menggunakan PCA pada model KNN yang menghasilkan lima komponen utama dengan varian kumulatif >80%. Nilai k optimal ditentukan melalui 10-Fold Cross Validation dengan hasil terbaik pada k=16. Hasil evaluasi menunjukkan PCA-KNN mencapai akurasi 76,47%, sensitivitas 90,00%, dan spesifisitas 50,94%, lebih baik dibanding KNN standar. Sementara itu, SVM memperoleh akurasi 72,73% dengan spesifisitas tinggi (84,00%) namun sensitivitas rendah (51,85%). Temuan ini mengindikasikan bahwa PCA-KNN lebih sesuai untuk skrining awal karena sensitivitas tinggi, sedangkan SVM dapat digunakan pada tahap konfirmasi berkat spesifisitas yang lebih baik.
