Judul: Determinan Penyerapan Tenaga Kerja Sektor Manufaktur di Negara-negara ASEAN
Abstrak: The manufacturing sector drives economic growth, and labor is a crucial factor in its production activity. This study analyzes the determinants of labor absorption in the manufacturing sector of ASEAN countries from 2011 to 2021. Using descriptive analysis, we examine the labor absorption situation in the manufacturing sector across 9 ASEAN countries, combining cross-section and time series data spanning 11 years. Employing a panel data regression model (Fixed Effect Model), we find that labor productivity, population growth, and trade openness have a positive and significant impact on manufacturing labor absorption. Conversely, inflation has a negative and significant effect. However, variables such as gross domestic product (GDP) growth and manufacturing value-added do not significantly influence manufacturing labor absorption., Sektor manufaktur memiliki peran penting dalam mendorong pertumbuhan ekonomi, dan tenaga kerja merupakan faktor kunci dalam aktivitas produksinya. Studi ini menganalisis faktor-faktor penyerapan tenaga kerja di sektor manufaktur negaranegara ASEAN dari tahun 2011 hingga 2021. Dengan menggunakan analisis deskriptif, kami mengkaji kondisi penyerapan tenaga kerja di sektor manufaktur di 9 negara ASEAN, dengan menggabungkan data cross-section dan time series selama 11 tahun. Dengan menerapkan model regresi data panel (Fixed Effect Model), kami menemukan bahwa produktivitas tenaga kerja, pertumbuhan penduduk, dan keterbukaan perdagangan memiliki dampak positif dan signifikan terhadap penyerapan tenaga kerja di sektor manufaktur. Sebaliknya, inflasi memiliki dampak negatif dan signifikan. Namun, variabel seperti pertumbuhan produk domestik bruto (PDB) dan tambahan nilai manufaktur tidak berpengaruh signifikan terhadap penyerapan tenaga kerja di sektor manufaktur.

Judul: Determinant of Labor Absorption in Lower Middle-Income Country
Abstrak: Tenaga kerja sebagai salah satu faktor produksi merupakan salah satu hal yang essensial dalam pertumbuhan ekonomi suatu negara. Dengan meningkatnya populasi dari tahun ke tahun, kontribusi sumber daya manusia dalam aktivitas ekonomi menjadi salah satu faktor pembangunan ekonomi. Penelitian ini bertujuan untuk menganalisis determinan dari penyerapan tenaga kerja di negara Lower Middle Income (LMC) selama periode tahun 2011-2020. Metode analisis yang digunakan adalah analisis deskriptif kualitatif untuk menggambarkan terkait kondisi penyerapan tenaga kerja di negara Lower Middle Income (LMC) serta analisis data panel untuk menganalisis faktor-faktor yang memengaruhi penyerapan tenaga kerja di negara Lower Middle Income (LMC) dengan menggunakan data cross section 10 negara LMC dan time series selama 10 tahun dari tahun 2011 hingga 2020. Model regresi data panel yang digunakan ialah Fixed Effect Model (FEM) dengan hasil estimasi menunjukkan bahwa variabel pertumbuhan Gross Domestic Product (GDP), produktivitas tenaga kerja, serta Foreign Direct Invesment berpengaruh positif dan signifikan terhadap tenaga kerja, sedangkan variabel ekspor memberi pengaruh negatif dan signifikan terhadap penyerapan tenaga kerja. Variabel lainnya yakni inflasi berpengaruh tidak signfikan terhadap penyerapan tenaga kerja., Labor as a factor of production is one of the essential things in the economic growth of a country. Population increases from year to year, the contribution of human resources in economic activity is one of many factors that affecting economic development. This research aims to analyze the determinants of employment in Lower Middle Income (LMC) Countries during 2011 until 2020. The analytical method that we used is qualitative descriptive analysis to provide an overview of the conditions of employment in Lower Middle Income (LMC) Countries and we used panel data regression analysis to analyze the factors that affecting employment in Lower Middle Income (LMC) Countries by using cross data. section for 10 LMC countries and time series for 10 years during the period 2011 until 2020. We used Fixed Effect Model (FEM) for panel data regression analysis, the results showing that GDP growth variable, labor productivity, Foreign Direct Investment has a positive and significant effect on labor absorption. Meanwhile, the export variables had a negative and significant effect on labor absorption. Another variable such as inflation had no significant effect on labor absorption.

Judul: Pola Pewarisan Karakter Suara Kicauan Pada Burung Perkutut
Abstrak: Turtledove (Geopelia striata) is a singing birds that has a better melodious voice. The inheritance of this character has not been determined, so that research on the voice inheritance is important. This study was aimed to characterize the voice patterns turtledove. Materials consisted of 12 pairs of parents and their progenies. Twelve of their turtledove was ranked based on their sound quality. The parameters observed included voice patterns, the presence of elements of sound, the type of sound, harmonious sound (frequency and level of sound intensity) and duration of the total sound. Voice analysis was done by using computer software Cool Edit Pro version 2.1. Sound visualization was displayed in waveform shape. Sound intensity level was determined using the formula TI = 10 log I/I0, with the value I0 at 10-12 W/m2. Based on the inheritance analysis sire voices is a better chance in herediting of the voice and the number of beats sound of the middle voice. Dam plays an role in giving voice rhythm modification and sound tip inheritance. Based on the sound analysis, sound quality the voice rank from the highest to the lowest were: ♂AK, ♂ FQ, ♂HHa, ♂ ISS, ♂HRR, ♂ BL, ♂CM, ♂ EQ, ♂GQ, ♂DO, ♂DN, and ♂DP. The frequency value and the highest intensity level displayed by AK turtledove were 929.49 Hz and 91.5 dB, whereas the lowest value displayed by ♂DP were 633.59 Hz, and 67.83 dB. The best rhythm of the turtledove indicated by high frequency with a stable pattern, harmonious the intonation, as well as clear basic voice.
