Abstract

This research aims to form a mathematical model in the problem of optimizing the average yield of cassava and soybean yields in West Pasaman Regency based on data from the West Pasaman Statistics Agency from 2007 to 2017 regarding the harvest area and average production of cassava and soybeans. The solution to the average production optimization problem uses the Wolfe's Method of Quadratic Programming. Wolfe method is used using a two-stage simplex iteration. The mathematical model formed is a non-linear equation. The estimation of parameters in the mathematical model uses the least squares method, which is calculated using the Matlab software. Optimization results using the Wolfe Method Quadratic Programming obtained an average of 340.95 kw / ha of cassava and soybeans, with an optimal harvest area of 255.38 ha of cassava and 469.5 ha of soybean harvest area.

Abstract

The purpose of this study is to examine how individual competence and internship satisfaction affect trainees' career motivation at Harris Resort Barelang Batam. This study employed a quantitative approach with a causal-associative research design. Purposive sampling was used to select 80 respondents from the study population, consisting of trainees from Batches 14 and 15 at Harris Resort Barelang Batam. Data were collected using a five-point Likert scale questionnaire. The data were analyzed using multiple linear regression with SPSS version 27, supported by validity, reliability, classical assumption, t-test, and F-test analyses. The findings indicate that internship satisfaction has a positive and significant effect on career motivation (β = 0.161; p = 0.025). In addition, individual competence has a positive and significant effect on career motivation (β = 0.764; p < 0.001). Simultaneously, internship satisfaction and individual competence have a significant effect on career motivation (F = 19.164; p < 0.001). These findings suggest that trainees' motivation to pursue a career in the hospitality industry can be enhanced through satisfying internship experiences and strong individual competence. Therefore, higher education institutions and industry partners should improve the quality of internship programs while supporting the development of trainees' competencies to strengthen work readiness and career motivation in the hospitality industry.

Abstract

Ketimpangan produktivitas antara petani kelapa sawit swadaya dan perkebunan besar masih menjadi tantangan bagi industri sawit nasional. Penelitian ini bertujuan untuk menganalisis efektivitas pelaksanaan kawalan budidaya melalui "Program Makmur" serta memetakan faktor pendukung dan penghambatnya di Desa Sumber Agung, Kabupaten Musi Banyuasin. Menggunakan metode Mixed Methods dengan desain sekuensial eksplanatoris, studi ini melibatkan 69 petani yang. Data dianalisis menggunakan uji Paired Sample T-Test untuk membandingkan produktivitas serta regresi linear berganda untuk mengukur pengaruh variabel kontrol budidaya. Hasil penelitian menunjukkan lonjakan produktivitas yang signifikan, di mana rata-rata hasil panen meningkat dari 1,37 ton/bulan menjadi 1,56 ton/bulan setelah intervensi program. Dari variabel yang diuji, adopsi hasil uji tanah (X2) ditemukan sebagai faktor paling dominan dengan nilai t-hitung 4,643 dan signifikansi 0,001. Secara ilmiah, dominasi ini membuktikan bahwa ketepatan asupan nutrisi berdasarkan status hara riil tanah jauh lebih efektif dalam mendongkrak hasil panen dibandingkan praktik konvensional yang bersifat spekulatif. Secara simultan, kepatuhan prinsip 4T, adopsi uji tanah, dan pendampingan agronomis memberikan kontribusi sebesar 88,2% terhadap peningkatan produktivitas. Faktor pendukung utama mencakup tingginya motivasi petani, usia produktif dan kemudahan akses pupuk berkualitas, sementara hambatan logistik saat musim hujan menjadi kendala operasional utama. Secara praktis, penelitian ini menggarisbawahi vitalnya peran Mobil Uji Tanah (MUT) sebagai instrumen transformasi menuju pertanian presisi bagi petani swadaya. Dari sisi kebijakan, disarankan bagi otoritas terkait untuk memperluas jangkauan Program Makmur dengan memperkuat struktur pendampingan lapangan guna memutus ketergantungan pada cara tradisional dan memastikan kesejahteraan ekonomi jangka panjang bagi sektor perkebunan rakyat.
