Analisis Optimalisasi Produksi Selada pada Berbagai Varietas dan Media Tanam untuk Meningkatkan Profitabilitas CV RB Farm

Abstract

TIFANY CLAUDYA SIALLAGAN. Analisis Optimalisasi Produksi Selada pada Berbagai Varietas dan Media Tanam untuk Meningkatkan Profitabilitas CV RB Farm. Dibimbing oleh DAHRI TANJUNG.

CV RB Farm berada pada tingkat produktivitas tertinggi sebesar 8.321 kg pada tahun 2024 tetapi memiliki potensi kapasitas produksi hingga 17.676 – 26.520 kg per tahun, sehingga keuntungan relatif terbatas dan efisiensi biaya belum optimal. Untuk meningkatkan kinerja usaha, dilakukan pengujian tiga varietas (Captiva, Kriebo, dan Seriti) serta dua media tanam (rockwool dan spons) dalam sistem Nutrient Film Technique (NFT). Analisis yang dipakai menggunakan ANOVA Two Way, uji Duncan Multiple Range Test (DMRT), dan regresi linear berganda guna menilai pengaruh faktor utama maupun interaksinya terhadap bobot panen, waktu panen, dan tingkat kehilangan hasil. Hasil penelitian menunjukkan bahwa varietas berpengaruh nyata terhadap bobot dan waktu panen, sedangkan media tanam memengaruhi waktu panen serta kehilangan hasil. Interaksi keduanya signifikan pada bobot panen dan kehilangan hasil. Kombinasi Captiva–rockwool memberikan bobot panen tertinggi (34.825 g), kehilangan hasil rendah (3,025%), serta peningkatan keuntungan hingga 64%. Nilai R/C ratio meningkat dari 2,16–2,21 menjadi 2,96–3,03, dan B/C ratio dari 1,21 menjadi 2,03.

TIFANY CLAUDYA SIALLAGAN. Production Optimization Analysis of Lettuce across Different Varieties and Growing Media to Enhance the Profitability of CV RB Farm. Supervised by DAHRI TANJUNG.

CV RB Farm reached its highest productivity level of 8.321 kg in 2024, but it still has the potential production capacity of up to 17.676 – 26.520 kg per year. This condition results in relatively limited profits and suboptimal cost efficiency. To improve business performance, three lettuce varieties (Captiva, Kriebo, and Seriti) and two growing media (rockwool and sponge) were tested under the Nutrient Film Technique (NFT) system. The analysis employed Two-Way ANOVA, Duncan Multiple Range Test (DMRT), and multiple linear regression to evaluate the main effects and interactions of the treatments on yield weight, harvest time, and postharvest losses. The results showed that variety had a significant effect on yield weight and harvest time, while the growing media significantly affected harvest time and postharvest losses. The interaction between the two factors was significant for yield weight and postharvest losses. The combination of Captiva–rockwool produced the highest yield weight (34,825 g), the lowest postharvest loss (3.025%), and increased profits by up to 64%. The R/C ratio increased from 2.16–2.21 to 2.96–3.03, while the B/C ratio rose from 1.21 to 2.03.
