Abstract

The aim of this study is to obtain the basic wood properties of three lesser known species tengkook ayam (Nephelium sp), madang pirawas (Neolitsea firma) and merambung (Vernonia arborea)). Stem diameter at 1.3 m above the ground and tree height were measured on 3 trees from each species. Later, core samples were collected from all the measured trees. Using the core samples, the basic density (BD), moisture content (MC) and compressive strength with fractometer (fractometer II, IML, German) parallel to grain (CS) were measured. Mean values of BD of tengkook ayam (Nephelium sp), madang pirawas (N. firma) and merambun (V. arborea) were 0.59±0.02, 0.55±0.06 and 0.34±0.06, respectively. Mean values of MC of tengkook ayam (Nephelium sp), madang pirawas (N. firma) and merambung wood (V. arborea) were 22.77±0.10%, 37.10±0.01% dan 61.85±0.06%, respectively. Mean values of CS of tengkook ayam (Nephelium sp), madang pirawas (N. firma) and merambung (V. arborea) were 34.70±11.89 MPa, 32.00±3.39 MPa dan 15.02±4,06 MPa. There is a positive significant correlation between BD and CSPenelitian ini bertujuan untuk mengetahui informasi dasar dari kayu tengkook ayam (Nephelium sp), madang pirawas (Neolitsea firma), dan merambung (Vernonia arborea). Diameter diukur pada ketinggian 1,3 m dari permukaan tanah pada 3 pohon dari masing-masing spesies. Core sample diambil dari pohon yang telah diukur. Menggunakan core sample pengukuran kekuatan tekan dengan fractometer dilakukan dengan memotong core sample menjadi 5 mm interval. Core sample dengan 5 mm interval kemudian diletakkan pada alat fractometer (Fractometer II, IML, Jerman) dan ditekan sampai kayu tersebut retak dengan menggunakan alat tersebut. Hasil penelitian berat jenis dari kayu tengkook ayam, madang pirawas dan merambung secara berturut-turut yaitu 0,59±0,02, 0,55±0,06 dan 0,34±0,06. Hasil penelitian kadar air dari kayu tengkook ayam, madang pirawas dan merambung secara berturut-turut yaitu 22,77±0,10%, 37,10±0,01% dan 61,85±0,06%. Hasil penelitian kekuatan tekan pada kayu tengkook ayam, madang pirawas dan merambung secara berturut-turut yaitu 34,70±11,89 MPa, 32,00±3,39 MPa dan 15,02±4,06 MPa. Hasil yang didapatkan menunjukkan bahwa korelasi antara berat jenis dengan kekuatan tekan yaitu 1. Artinya semakin besar berat jenisnya maka akan semakin besar juga kekuatan tekan yang dihasilkan

Abstract

This study aims to analyze the effect of investment decisions and stock prices on the company value in the infrastructure sector, moderated by profitability. The study uses multiple linear regression to examine the relationships between variables, with secondary data obtained from the financial statements of infrastructure companies listed on the Indonesia Stock Exchange (IDX) for the period of 2018-2021. The independent variables used in this study are investment decisions, measured by the Price Earnings Ratio (PER), stock price, measured by closing share price, and profitability, measured by Return on Equity (ROE). The dependent variable is company value, measured by Price to Book Value (PBV). The results of the study show that investment decisions and stock prices have a positive and significant effect on company value. However, profitability does not moderate the relationship between investment decisions and stock prices on company value. The implications of this study’s findings suggest that infrastructure companies should pay attention to investment decisions and strategies that can influence stock prices, as both have a significant impact on increasing company value. Additionally, although profitability does not moderate the relationship, companies should still maintain profitable performance to ensure the sustainability of healthy operations.

Abstract

Community economic empowerment is widely recognized as a strategic instrument for accelerating the achievement of the Sustainable Development Goals (SDGs), particularly in developing regions. This empirical study examines the role of community economic empowerment management in supporting SDGs achievement in Hulu Sungai Utara Regency, South Kalimantan, Indonesia. Employing a mixed-methods approach, the study integrates quantitative survey data from 120 respondents with qualitative in-depth interviews involving 15 key informants, supported by secondary data analysis and a review of reputable literature. The findings reveal that effective empowerment management characterized by structured planning, access to capital, training effectiveness, institutional coordination, and outcome-based monitoring has a significant positive impact on income improvement, business sustainability, and employment stability. Although Hulu Sungai Utara Regency demonstrates a relatively low poverty rate, managerial and institutional challenges limit the optimal contribution of empowerment programs to SDGs targets. This study contributes empirical evidence from a local Indonesian context and proposes a management-oriented framework for aligning community empowerment initiatives with sustainable development agendas

Abstract

Penelitian ini bertujuan menguji pengaruh intensitas pengungkapan Artificial Intelligence (AI) dalam laporan tahunan terhadap kinerja keuangan perbankan yang diukur menggunakan Return on Assets (ROA) dan Return on Equity (ROE). Intensitas pengungkapan AI diukur melalui analisis isi berbasis lexicon dengan menghitung frekuensi kemunculan istilah AI yang dinormalisasi terhadap total kata laporan (AI mentions per 10.000 kata). Sampel penelitian meliputi tiga bank (BMRI, BBRI, BBNI) periode 2022–2024 (9 observasi firm-year). Analisis dilakukan menggunakan statistik deskriptif, korelasi Pearson, dan regresi OLS pooled. Hasil menunjukkan intensitas pengungkapan AI tidak berpengaruh signifikan terhadap ROA maupun ROE dengan arah koefisien negatif (ROA: β = -0,283; p = 0,575; ROE: β = -3,901; p = 0,322). Temuan ini mengindikasikan bahwa narasi AI pada laporan tahunan belum dapat dijadikan indikator peningkatan profitabilitas akuntansi jangka pendek dan dapat bersifat strategis (signaling/legitimasi atau impression management)
