Abstract

Limbah industri kelapa sawit yang memiliki potensi untuk dijadikan pupuk organik dan tersedia cukup banyak di Provinsi Riau adalah abu boiler. Penelitian ini bertujuan untuk menentukan dosis abu boiler kelapa sawit terhadap tanaman selada. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) non faktorial terdiri dari 4 perlakuan dan 3 ulangan yaitu: P0 (Kontrol), P1 (176 g abu boiler kelapa sawit), P2 (352 g abu boiler kelapa sawit), dan P3 (528 g abu boiler kelapa sawit). Parameter yang diamati meliputi tinggi tanaman (cm), jumlah daun (helai), dan lebar daun (cm). Berdasarkan hasil ANOVA pada taraf 5%, pemberian abu boiler kelapa sawit pada memberikan pengaruh terhadap tinggi tanaman, jumlah daun, dan lebar daun tanaman selada. Dosis abu boiler kelapa sawit  terbaik pada tinggi tanaman, jumlah daun, dan lebar daun  tanaman selada adalah 352 g/polybag. The industrial palm oil waste with potential to be used as organic fertilizer and abundantly available in Riau Province is boiler ash. This study aims to determine the optimal dosage of palm oil boiler ash for lettuce plants. The research employed a Randomized Block Design (RBD) consisting of 4 treatments and 3 replications, namely: P0 (Control), P1 (176 g of palm oil boiler ash), P2 (352 g of palm oil boiler ash), and P3 (528 g of palm oil boiler ash). Observed parameters included plant height (cm), number of leaves (pieces), and leaf width (cm). Based on the results of ANOVA at a 5% significance level, the application of palm oil boiler ash significantly influenced the height, number of leaves, and leaf width of lettuce plants. The optimal dosage of palm oil boiler ash for plant height, number of leaves, and leaf width was 352 g/polybag.

Abstract

Aims and Methods: Oil palm is a strategic commodity that contributes significantly to Indonesia's economy. The losses of oil palm loose fruits during the harvesting and transportation processes of fresh fruit bunches (FFB) pose a serious challenge for oil palm plantation industry, with potential losses reaching 3–7% of total production. This study aims to analyze the distribution pattern of the losses of loose fruits at three observation points (weed circle, carrying market, and harvest collection point (HCP)) at Agritasari Prima Ltd., calculate the economic loss due to these losses, and identify the causative factors. This study employs a qualitative descriptive survey method with sampling at three plantation divisions on flat terrain, covering 1,260 weed circles, 21 carrying markets, and 144 HCPs.Results: The highest loss distribution occurred at carrying market (47.66 fruits/carrying market), followed with weed circle (10.15 fruits/circle) and HCP (8.14 fruits/site). The total economic loss reached IDR 463,143.83, with the largest contribution coming from the losses at weed circle of 85.44% (IDR 395,808), followed by HCP of 7.86% (IDR 36,307), and carrying market of 6.70% (IDR 31,028.83). The annual economic loss due to the losses of loose fruits on flat terrain at Agritasari Prima Ltd. is estimated at IDR 2,178,282,597.31 (around IDR 2.18 billion per year). Major causative factors comprise poorly maintained weed circles, overloaded wheelbarrows, poor route infrastructure at carrying markets, and suboptimal handling at HCPs.Conclusion: Implementation of regular maintenance programs, standardization of vehicles’ capacity, infrastructure improvements, and digital monitoring systems are recommended to reduce the level of losses of loose fruits and improve oil palm plantation operational efficiency.
