Abstract

Nutrient uptake efficiency in sugarcane (Saccharum officinarum L.) must be increased using organic matter to restore soil fertility, resulting in greater productivity. The humic substance is a complex organic material that is excellent for overcoming this challenge. This study aimed to determine the effect of the humic acid enriched by liquid urea by-product (PSUC) and liquid NPK by-product (PSNC) application on the growth and productivity of sugarcane. The experiment was conducted from October 2021 to September 2022 on PT RNI plantation land, Jatitujuh, Majalengka. The research was arranged in a completely randomized (CRD) using two different humic acid product prototypes (PSUC and PSNC) with two evaluation times, a screening and a semi-pilot scale. Solid humic at a dose of 15 Kg ha⁻¹ was applied by mixing it with inorganic fertilizers, while liquid humic at a total dose of 15 L ha⁻¹ was applied by foliar spray technique at 1, 2, and 3 months after planting (MAP). The results showed that applying humic acid PSUC and PSNC enhanced sugarcane shoot growth, segmented stem number, and diameter. In addition, it could consistently promote sugarcane yields on the semi-pilot scale up to 19.18% and 24.26% under humic acid PSUC and PSNC treatments, respectively. Therefore, both in the screening and semi-pilot evaluation, the solid and liquid humic acid PSUC and PSNC applied simultaneously are potential organic materials to enhance sugarcane growth and yield.

Abstract

Medium-chain Triglycerides (MCT) merupakan senyawa lemak fungsional yang semakin mendapat perhatian dalam industri pangan dan kesehatan global karena karakteristik metabolik dan fisiologisnya yang unggul. Dibandingkan trigliserida rantai panjang (LCT), MCT lebih cepat diserap dan digunakan tubuh sebagai sumber energi, sehingga diaplikasikan luas dalam diet ketogenik, nutrisi klinis, serta suplemen olahraga. Hingga saat ini, minyak kelapa menjadi sumber utama bahan baku MCT karena kandungan asam lemak rantai sedang (MCFA) yang tinggi, namun keterbatasan suplai dan harga yang tinggi membatasi skalabilitasnya secara global. Kajian ini mengulas potensi minyak inti sawit (PKO) sebagai bahan baku alternatif untuk produksi MCT berbasis kelapa sawit. Selain ketersediaannya yang tinggi di Indonesia (>5 juta ton/tahun), PKO memiliki kandungan MCFA signifikan, terutama asam laurat (C12), serta harga yang lebih kompetitif dibanding minyak kelapa. Dari sisi teknologi, berbagai pendekatan sintesis MCT telah dikembangkan, mulai dari reaksi kimiawi, enzimatik, hingga rekayasa molekuler berbasis mikroorganisme dan mikroalga. Beberapa penelitian juga menunjukkan potensi ekonomi sirkuler dengan memanfaatkan distilat PKO sebagai bahan baku bernilai tambah tinggi. Indonesia memiliki peluang strategis untuk menjadi produsen utama MCT global karena rantai pasok sawit yang terintegrasi, skala produksi besar, dan dukungan kebijakan hilirisasi nasional. Pengembangan teknologi produksi MCT berbasis PKO tidak hanya mendukung daya saing industri sawit, tetapi juga membuka peluang komersialisasi produk turunan sawit bernilai tinggi di sektor kesehatan global.
