Abstract

Pemanfaatan kitosan asap cair dalam meningkatkan pertumbuhan cabai rawit merah Capsicum frutescens penting dipelajari karena kebutuhan cabai rawit merah meningkat setiap tahunnya namun tidak disertai dengan peningkatan produktifitas yang seimbang. Penelitian ini bertujuan untuk mengetahui dosis kitosan asap cair yang paling optimal dalam mendukung pertumbuhan cabai rawit merah. Rancangan Acak Lengkap (RAL) faktorial menggunakan empat ulangan dengan pemberian dosis kitosan asap cair sebesar 5, 7,5, 10, 12,5 dan 15% digunakan dalam penelitian. Parameter yang diamati adalah rasio C/N tanah, tinggi tanaman, jumlah daun, berat kering tanaman. Sebelum ditanam selama delapan minggu, biji cabai direndam dalam larutan akuades dan kitosan asap cair. Hasil menunjukkan bahwa penggunaan dosis kitosan asap cair sebesar 7,5% dan 10% menunjukkan pertumbuhan yang paling optimal berdasarkan tinggi tanaman, jumlah daun, berat kering tanaman dibandingkan dosis lainnya.

Abstract

Heterotrigona itama is a stingless bee species that produces high-quality and economically valuable honey. Honey quality assessment can be done through physicochemical parameters according to applicable standards. This study aims to analyze the physicochemical quality of Heterotrigona itama honey from three meliponiculture locations in Sungai Tiung Village, Banjarbaru City and compare it with SNI 8664-2018 and U.S. Patent Application Publication-2011. The study used purposive sampling method by taking samples from Cempaka Madu Kelulut, Cempaka Beton, and Kelulut Kalimantan. Parameters tested included moisture content, total sugar, HMF, reducing sugar, sucrose, acidity, water insoluble solids, ash content, and Pb and Cd metal contamination based on the method in SNI. Data analysis was done descriptively quantitatively. The results showed that all samples had a moisture content of 30-30.33%, total sugar 67.7-68°Brix, HMF 15.3-15.8 mg/kg, reducing sugar 33.88-45.59%, sucrose 7.88-10.58%, acidity 85.33-100 mL NaOH/kg, water insoluble solids 0.35-1.15%, ash content 0.056-0.1%, and Pb and Cd contamination <0.0001 mg/kg. Most parameters met the SNI, while the water content, reducing sugar, and sucrose exceeded the set limits.
