Abstract

Perkebunan kelapa sawit memiliki peran strategis dalam perekonomian Indonesia, terutama dengan meningkatnya permintaan Crude Palm Oil (CPO). Penelitian ini bertujuan untuk mengoptimalkan produksi CPO di PTPN IV Regional 4 dengan menerapkan pendekatan linear programming metode simpleks. Permasalahan yang dihadapi meliputi biaya produksi dan operasional, kapasitas tangki minyak, jam olah efektif mesin, serta distribusi Tandan Buah Segar (TBS) dari tiga kebun, yaitu Bunut, Batang Hari, dan Lagan. Metode penelitian yang digunakan adalah linear programming dengan metode simpleks, yang diimplementasikan melalui perhitungan manual dan simulasi menggunakan software POM-QM. Data penelitian diperoleh dari sumber primer dan sekunder, termasuk wawancara dengan pegawai PTPN IV serta analisis dokumen produksi tahun 2023. Hasil penelitian menunjukkan bahwa alokasi optimal TBS untuk mencapai produksi CPO maksimal adalah 10.680 ton dari kebun Bunut, 4.050 ton dari kebun Batang Hari, dan 3.752 ton dari kebun Lagan per bulan. Dengan alokasi ini, produksi CPO dapat mencapai 4.320,14 ton per bulan, meningkat 723,14 ton dari rata-rata produksi sebelumnya. Simpulan penelitian mengonfirmasi bahwa penerapan metode simpleks efektif dalam mengoptimalkan produksi CPO, dengan hasil yang signifikan dibandingkan studi sebelumnya.

Abstract

This study aims to analyze the effect of Employee Engagement and Work Life Balance on employee performance through job satisfaction. The variables studied include Employee Engagement and Work Life Balance as independent variables, Employee performance as dependent variables, and job satisfaction as intervening variables. The study was conducted on employees of PTPN VI Kebun Pabatu, Dolok Merawan District, Serdang Bedagai Regency. The number of research samples was 51 people, determined using the Taro Yamane formula. This study uses primary data obtained by using questionnaires distributed to employees. The data analyzed using the path analysis method. The results of the study showed that Employee Engagement did not have a significant effect on Job Satisfaction, while Work-Life Balance had a significant effect on Job Satisfaction. Furthermore, Employee Engagement was proven to have a significant effect on Employee Performance, while Work-Life Balance did not have a significant effect on Employee Performance. This study also found that Job Satisfaction had a significant effect on Employee Performance. In addition, Job Satisfaction was able to mediate the effect of Employee Engagement on Performance, but was unable to mediate the effect of Work-Life Balance on Performance.

Abstract

This research aims to describe the types of errors made by class VII D students of SMP Negeri 7 Palu in solving line and angle problems based on gender. Data was obtained from the results of written assignments and interviews. The research subjects consisted of one male student (AA) and one female student (YS). The results of the research show that there are similarities and differences between male and female students in making written assignments number 1 and 2. Male and female students make the same mistakes in written assignment number 1. The similarities are: 1) Errors of not understanding the concept of the relationship between angles that are supplementary to each other, 2) the error of not understanding the concept of the relationship between the interior and exterior angles of a triangle, 3) the error of not solving the problem according to the instructions, 4) the error of not being coherent in the calculation steps, 5) the error of using arithmetic operation signs, 6) Error calculating the value of a calculation operation. Meanwhile, in written assignment number 2, there were differences in errors made by male and female students. The male students' mistakes were: 1) The male students were correct in doing the questions according to the instructions but not completely or comprehensively, 2) The male students were not careful and rushed in solving the questions. The female student's mistakes in written assignment number 2 were: 1) The female student was correct in choosing the formula but could not apply the formula, 2) The female student solved the problem not according to the procedure ordered. The similarity between male and female students in completing written assignment number 2 is that in the problem solving procedure they can group similar and dissimilar terms in the written assignment.

Abstract

This research aims to obtain a description or portrayal of the conceptual understanding of 8th-grade students in class G at SMP Negeri 3 Palu in solving statistics problems, with a focus on gender differences. This study adopts a descriptive research design with a qualitative approach. The research subjects are 8th-grade students in class G at SMP Negeri 3 Palu. Data were collected through written tests and interviews. The results of this research indicate that male students have a better conceptual understanding compared to female students based on conceptual understanding indicators. Male students can fulfill four out of five indicators, while female students fulfill three out of five conceptual understanding indicators. Both male and female students can articulate the concepts of mean, median, and mode in their own words. They can present data in table form with the correct arrangement. Male and female students can solve mean problems using appropriate algorithms. Male students can classify modes, whereas female students struggle to classify modes accurately. Both male and female students find it challenging to associate the concept of median with the concept of mean.

Abstract

Fenomena phubbing, yaitu kebiasaan mengabaikan orang di sekitar karena terlalu fokus pada ponsel, menjadi masalah serius di lingkungan sekolah, terutama di SMK Abdul Aziz Balung Jember. Perilaku ini dapat mengganggu hubungan sosial antar siswa, mengurangi empati, serta menghambat komunikasi yang baik. Karena kesadaran rendah dan intervensi psikologis yang minim, perlu dilakukan penelitian untuk mengatasi masalah ini. Tujuan penelitian ini adalah mengetahui sejauh mana konseling kelompok dengan keterampilan empati dapat mengurangi perilaku phubbing. Penelitian ini menggunakan metode quasi eksperimen dengan desain kelompok kontrol yang tidak setara. Subjek penelitian terdiri dari dua kelompok, yaitu kelompok eksperimen yang menerima konseling kelompok dengan keterampilan empati, dan kelompok kontrol yang tidak menerima perlakuan apa pun. Alat yang digunakan adalah skala perilaku phubbing yang telah diuji validitas dan reliabilitasnya. Data dianalisis menggunakan uji statistik paired sample t-test dan independent sample t-test. Hasil menunjukkan bahwa rata-rata perubahan skor perilaku phubbing pada kelompok eksperimen adalah 23,13 dengan standar deviasi 2,23, sedangkan pada kelompok kontrol hanya 4,00 dengan standar deviasi 0,53. Perbedaan ini menunjukkan bahwa kelompok eksperimen mengalami penurunan signifikan dalam perilaku phubbing dibandingkan kelompok kontrol. Ini menunjukkan bahwa konseling kelompok dengan keterampilan empati efektif dalam mengurangi phubbing.
