Abstract

Pemangkasan pada tanaman teh yang dilakukan di kebun teh produktif menyebabkan sebagian besar atau secara keseluruhan organ fotosintesis tanaman hilang dan diperlukan waktu sekitar 2-3 bulan utuk tumbuh kembali. Pemangkasan dilakukan dengan jenis dan tinggi pangkasan yang bervariasi. Penambahan sitokinin benzil amino purine (BAP) dan giberelin (GA) diharapkan dapat mempercepat pertumbuhan pucuk setelah dipangkas. Tujuan penelitian adalah mempelajari pengaruh pemangkasan serta aplikasi BAP dan GA terhadap pertumbuhan dan hasil pucuk teh. Percobaan dilaksanakan kebun percobaan Pusat Penelitian Teh dan Kina Gambung bulan Agustus 2017-Oktober 2018 menggunakan rancangan split-split plot terdiri dari jenis pemangkasan (pemangkasan bersih dan pemangkasan ajir) sebagai petak utama, tinggi pangkasan sebagai anak petak (40 cm, 50 cm, dan 60 cm), aplikasi BAP dan GA sebagai anak-anak petak (0 ppm, 60 ppm BAP, 50 ppm GA, 60 ppm BAP+ 50 ppm GA). Hasil penelitian menunjukkan bahwa pemangkasan bersih dan 60 ppm BAP + 50 ppm GA menghasilkan pertumbuhan terbaik pada tinggi tunas. Tinggi pangkasan 60 cm dan 60 ppm BAP menunjukkan indeks klorofil daun tertinggi bulan ke-3 sebesar 91.58 (lebih tinggi daripada hasil penelitian sebelumnya yaitu 62.5-75.28), sedangkan tinggi pangkasan 60 cm dan 60 ppm BAP + 50 ppm GA memberikan bobot basah pucuk per perdu tertinggi pada pemetikan produksi. Secara tunggal, tinggi pangkasan 50 cm menurunkan jumlah pucuk burung serta 50 ppm GA mempersingkat lamanya masa dormansi pucuk menjadi 22 hari. Kata kunci: dormansi pucuk, pucuk burung, teh produktif

Abstract

The excessive use of chemical fertilizers can damage ecosystems and reduce soil fertility, negatively impacting crop production. The addition of organic materials to the soil, such as empty fruit bunch (EFB) compost and humic acid, can mitigate these negative effects. The nutrient content in EFB compost can enhance plant growth, while humic acid can improve nutrient absorption by plants. This study aimed to determine the optimal combination of EFB compost and humic acid doses for achieving the best growth of mature phase oil palm in its first year of production. The research was conducted at the Ciparanje Experimental Farm, Faculty of Agriculture, Universitas Padjadjaran, Jatinangor, from February to June 2024, using a randomized block design (RBD) with four treatments and six replications. The treatments tested were: 2.5 kg/plant of NPKMg fertilizer (12:12:17:2); 50 kg/plant of EFB compost; 30 kg/plant of EFB compost + 300 mL/plant of humic acid; and 10 kg/plant of EFB compost + 300 mL/plant of humic acid. The results showed that, in general, there were no significant differences in most growth parameters observed. Significant differences were only found in the number of fronds, particularly at 2 and 4 weeks after treatment (WAT), with the application of 10 kg/plant of EFB compost + 300 mL/plant of humic acid yielding the best results.

Abstract

Coffee (Coffea arabica) is a globally significant beverage whose sensory profile and physiological effects derive from a complex matrix of secondary metabolites. This review presents a comprehensive "lifecycle" perspective of three pivotal classes: the alkaloid caffeine, phenolic chlorogenic acids (CGA), and the diterpenoids cafestol and kahweol. Here, 'lifecycle' defines a metabolite's continuous biochemical trajectory, tracking its genetic origin and ecological function in the plant through structural modifications during fermentation, drying, storage, and roasting. These classes are highlighted because they serve as the primary drivers of bitterness, acidity, and health bioactivities with fundamentally distinct transformational pathways. Following a systematic methodology, this study traces these compounds from biosynthesis to their fate during post-harvest processing. The synthesis reveals that post-harvest interventions cannot create quality but only modulate the bean's inherent chemical potential established by genetics and agronomy. Specifically, fermentation primarily reshapes hydrophilic phenolics (CGA) via hydrolysis to soften astringency, whereas roasting acts as a thermochemical trigger that degrades labile CGA into sensory critical melanoidin precursors and liberates insulated lipophilic diterpenoids. Current literature frequently compartmentalizes pre harvest plant omics and post-harvest food chemistry. This review addresses this gap by integrating these disciplines into a continuous mechanistic model, demonstrating how botanical origins inherently precondition processing outcomes. This holistic perspective offers practical insights for agronomists, processors, and roasters to predict, preserve, and intentionally enhance the sensory and bioactive profile of coffee across the supply chain.
