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

This study aims to determine the effect of application frequency of oil palm fronds’ local microorganisms (LMO) on the growth of Eucalyptus grandis CGP 105 seedlings, and to determine the application frequency that produce the best growth on Eucalyptus grandis CGP 105 plants. This study applied Randomized Block Design consisting of 5 treatments and 4 replications, namely P0: without LMO (control), P1: 1 time of application (7 days after planting/DAP), P2: 2 times of application (7 and 14 DAP), P3: 3 times of application (7, 14, and 21 DAP), and P4: 4 times of application (7, 14 , 21, and 28 DAP). The parameters observed were plant height (cm), leaf length (cm), leaf width (cm), number of leaves (strands), and stem diameter (mm). Based on ANOVA results at the 5% level, the application of oil palm fronds’ LMO on Eucalyptus grandis CGP 105 seedlings had a significant effect on all measured parameters. The best application frequency of oil palm fronds’ LMO is P4 treatment, which resulted in the average of plant height of 25.83 cm, leaf length of 7.47 cm, leaf width of 3.54 cm, number of leaves of 13.25 strands, and stem diameter of 2.45 mm. Penelitian ini bertujuan mengetahui pengaruh frekuensi pemberian mikroorganisme local (MOL) pelepah kelapa sawit (Elaeis guineensis Jacq.) terhadap pertumbuhan bibit Eucalyptus grandis CGP 105, serta mengetahui frekuensi pemberian MOL yang menghasilkan pertumbuhan terbaik pada tanaman Eucalyptus grandis CGP 105. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) yang terdiri dari 5 perlakuan dan 4 ulangan, yaitu P0: tanpa MOL (kontrol), P1: 1 kali pemberian (7 hari setelah tanam/HST), P2: 2 kali pemberian (7 dan 14 HST), P3: 3 kali pemberian (7, 14, dan 21 HST), dan P4: 4 kali pemberian (7, 14, 21, dan 28 HST). Parameter yang diamati meliputi tinggi tanaman (cm), panjang daun (cm), lebar daun (cm), jumlah daun (helai), dan diameter batang (mm). Hasil uji ANOVA pada taraf 5% menunjukkan bahwa pemberian MOL pelepah kelapa sawit pada bibit Eucalyptus grandis CGP 105 berpengaruh terhadap semua parameter yang diamati. Frekuensi pemberian MOL pelepah kelapa sawit terbaik adalah perlakuan P4, yang menghasilkan rerata tinggi tanaman 25,83 cm, panjang daun 7,47 cm, lebar daun 3,54 cm, jumlah daun 13,25 helai, dan diameter batang 2,45 mm.

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.
