Abstract

The goal of this study was determine the influence of honey harvesting age in the area of the calliandra plant to diastase enzyme activity, hidroxymetilfurfural (HMF) and acidity. The method of this study was experiments (RAL) with 3 treatments and five replication. The observations of this study were P1 (honey harvested in 11 days), P2 (honey harvested in 14 days), and P3 (honey harvested in 17 days). The variable in this study is the activity of diastase enzyme, hidroxymetilfurfural (HMF) and acidity. Data of this study were analyzed with the Range Analysis (ANOVA), if there is a significant difference between treatments, analysis of data was continued with the Smallest Real Difference Test (BNT). The results of this study showed that the honey harvesting age gave significant effect (p<0.01) on diastase enzymes activities, hidroxymetilfurfural and acidity. As a conclusion, honey harvesting age influences the quality of the activity of the diastase enzyme, hidroxymetilfurfural and acidity. The best content of diastase enzyme, was found in P3 treatment that is generated in 17th day of harvesting with the value 11.12 DN due to it was longer in the nest before harvested. The best content of hidroximetilfurfural was found in P3 with the value 4.48 mg/kg and the best content of acidity honey was found in P3 with the value 28.42 NaOH/kg.

Abstract

The purposes of this research were to investigate the difference of harvesting time on honey production, viscosity, moisture and sugar content, as well as identifying the best harvesting time.The material used in this research was honey from Calliandra plantation. The method used was experimental design using Completely Randomized Design (CRD) with 3 treatments and 5 replications. The treatment consisted of harvesting time on day 11 P1on day 14 P2, and on day 17 P3. Data obtained were analyzed by ANOVA and continued by LSD test. The results showed that the treatments had significantly effect (P<0.01) on honey production, viscosity, water and sugar content. On P1, production obtained was 1.59 L/colony/harvest, while 0.72 and 0,26 from P2 and P3, respectively. Moisture of P1, P2, P3 respectively were 22.02, 21.00, 19.48 %, respectively. Viscosity obtained was 11.43, 18.56, and 33.67 P. Sugar content were 69.46%, 70.59%, and 71.67%, respectively. In conclusion, viscosity and sugar content of honey will increase when it is harvested on day 17, but decrease when it is harvested on day 11. However, harvesting time on day 11 is the best choice for farmer due to highest production obtained, but inadequate of standard of water content, viscosity, and sugar content.

Abstract

Tujuan penelitian ini adalah untuk membandingkan aktivitas antioksidan, kadar total fenolik dan kadar total flavonoid propolis dari dua jenis lebah dan lokasi yang berbeda. Materi yang digunakan pada penelitian ini adalah propolis yang dihasilkan dari Apis mellifera dan Trigona sp. yang digembalakan di dua lokasi yang berbeda yaitu Batu dan Mojokerto. Metode yang digunakan adalah analisis deskriptif. Aktivitas antioksidan tertinggi dan terendah ditunjukkan oleh propolis Trigona sp. asal Mojokerto (987.24 µg/g) dan propolis Trigona sp. asal Batu (166.25 µg/g). Kadar total flavonoid tertinggi dan terendah ditunjukkan oleh propolis Apis mellifera asal Mojokerto (1.990 mg/g) dan propolis Trigona sp. asal Mojokerto (1.000 mg/g). Kadar total fenolik tertinggi dan terendah ditunjukkan oleh propolis Apis mellifera asal Mojokerto (21.980 mg/g) dan propolis Trigona sp asal Mojokerto (9.603 mg/g). Propolis Apis mellifera asal Mojokerto memiliki kandungan total flavonoid dan fenoil tertinggi dan propolis Trigona sp. asal Mojokerto memiliki nilai aktivitas antioksidan, total flavonoid dan total fenolik terendah.
