Abstract

The waters of Lubuk Gaung Village, Sungai Sembilan District are areas that are widely used as transportation routes. Activities in these waters will cause environmental pollution, which affects the life of phytoplankton. The purpose of this study was to determine the relationship between the primary productivity of phytoplankton with oceanographic parameters in the waters of Lubuk Gaung Village, Sungai Sembilan District, Dumai. The method used is the survey method to determine the research station and the in situ method for measurement and sampling of oceanographic parameters. The results obtained are Oceanographic parameters from the three research stations, namely Brightness = 30 – 49 cm, Turbidity = 47.4 – 58.4 FTU, TSS = 124 – 209 mg/L, and BOD = 0.408 – 1.224 mg/L. The average value of primary productivity of the waters ranged from 48.07 to 79.69 mgC/m3/day. The value of primary productivity at station II is categorized into Oligotrophic, namely low waters. Stations I and III are categorized into mesotrophic waters, namely medium waters. The relationship between brightness, turbidity, and TSS with primary productivity has a very strong and positive (unidirectional) correlation value. The relationship between BOD and primary productivity has a very strong and negative (opposite) correlation.

Abstract

This study is to determine the relationship between primary productivity and nutrients in the coastal waters of Pelintung Village, Medang Kampai District, Dumai. The research was conducted in March 2022; the method used in this research is survey method and purposive sampling. The research location is divided into 3 station points namely tourist area, secondary vegetation forest area, and near industrial area. The results of the measurement of the highest primary productivity value are found at Station III which is 78.91 mgC/m2/hour which indicates mesotrophic water conditions, while the lowest primary productivity value is at Station II, which is 46.88 mgC/m2/hour which indicates oligotrophic water conditions. The results of the analysis of the concentration of nitrate and phosphate between stations also varied, namely for the nitrate value of 0.04 – 0.05 mg/L which was included in the less fertile category, while the phosphate concentration was 0.042 – 0.048 mg/L which was included in the fertile category in the waters. Furthermore, the relationship between nitrate concentration and primary productivity is a correlation coefficient value (r) = -0.070 which means that there is a weak relationship between nitrate concentration and primary productivity. Meanwhile, the relationship between phosphate concentration and primary productivity is the correlation coefficient (r) = 0.965, which means that there is a very strong relationship between phosphate concentration and primary productivity. So it can be concluded that nitrate and phosphate nutrients can affect the primary productivity of water.

Abstract

Stingless bees are commonly found in Indonesia, either living naturally or managed in cultivation systems. The main factor determining the success of stingless bee farming is the availability and abundance of plants as food sources. This study aimed to determine the number and timing of foraging activities of stingless bees (Heterotrigona itama) for pollen, the influence of environmental factors on the foraging activities of H. itama for pollen, and the types of plants that have the potential to serve as pollen sources. The foraging activity of H. itama was directly observed from 06:00 to 18:00. The environmental parameters measured included temperature, humidity, and light intensity. The survey of potential pollen source plants was conducted around the managed colony boxes and within a 200-meter radius from the colony boxes. The results showed that H. itama foraging activity peaked at 11:00 (bees leaving the nest), 10:00 (bees returning to the nest without carrying pollen), and 11:00 (bees returning with pollen). Spearman correlation analysis indicated that pollen foraging activity was influenced by light intensity. The potential for pollen source plants around the study site was relatively abundant, with 37 plant species identified.

Abstract

Lebah tanpa sengat (Heterotrigona itama) dapat menghasilkan produk berupa madu, polen, propolis, dan royal jelly. Lebah tanpa sengat jenis ini banyak dibudidayakan karena kemudahan dalam mengelolanya, ketersediaan di alam yang masih banyak, dan produksi madunya yang lebih tinggi dibanding jenis lain. Teknik budidaya yang digunakan dapat menggunakan kota sarang sebagai sarangnya. Penelitian ini bertujuan untuk mengetahui volume madu dan berat polen lebah tanpa sengat (Heterotrigona itama) berdasarkan perbedaan ukuran kotak sarang yang tersedia dengan penerapan sistem topping di Hutan Adat Imbo Putui, serta jumlah pot madu dan pot polen yang dihasilkan. Metode penelitian yang digunakan adalah survei dan pengamatan langsung, dengan analisis deskriptif kuantitatif. Hasil penelitian menunjukkan bahwa ukuran kotak sarang 40 × 35 × 10 cm menghasilkan volume madu tertinggi sebesar 126,67 ml dan berat polen
