Abstract

This study aimed to describe the morphological characters and morphometric measurements of worker level from the genus and species of stingless bee colonies in coastal areas. Observation of morphological characters and morphometric measurements used a microscope (stereo model Nikon C-LEEDS equipped with obtilab viewers software camera and image raster). The stingless bee species found in coastal areas belonged to the genus Tetragonula which consisted of Tetragonula sapiens and T. clypearis. T. sapiens was found in two locations, namely the coast of Airlow Hamlet and Negeri Rutong. T. clypearis was found in four locations, i.e., on the coast of Dusun Airlow, Negeri Rutong, Negeri Hukurila and Dusun Seri. Morphological identification was done by identifying ten morphological characters, and morphometric identification was done by measuring fourteen body parts. The results of this study indicated that the morphological and morphometric characters of T. sapiens workers were dominantly black in color with a body size of 3.74-4.25 mm. The first through the sixth abdomen tergites were black. The morphological and morphometric characters T. clypearis had a brownish black body color with a body size of 2.81-3.38 mm, a black thorax covered by six longitudinal hair bands and each separated by five conspicuous glabrous, the first and second abdomen tergites were brownish whereas the third through the sixth were black. Keywords: Ambon Island, morphology, morphometric, stingless bees. ABSTRAK Penelitian ini bertujuan untuk mendeskripsikan karakter morfologi dan pengukuran morfometrik strata pekerja dari genus dan spesies lebah tak bersengat koloni daerah pesisir. Pengamatan karakter morfologi dan pengukuran morfometrik menggunakan mikroskop (stereo model Nikon C-LEEDS yang dilengkapi kamera software obtilab viewers dan image raster). Spesies lebah tak bersengat yang ditemukan di daerah pesisir pantai tergolong dalam genus Tetragonula yang terdiri dari Tetragonula sapiens dan T. clypearis. T. sapiens ditemukan di dua lokasi yaitu pesisir pantai Dusun Airlow dan Negeri Rutong. T. clypearis ditemukan di empat lokasi, yaitu di pesisir pantai Dusun Airlow, Negeri Rutong, Negeri Hukurila dan Dusun Seri. Identifikasi morfologi dilakukan dengan mengidentifikasi sepuluh karakter morfologi dan identifikasi morfometrik dilakukan dengan cara mengukur empat belas bagian tubuh. Hasil penelitian ini menunjukan karakter morfologi dan morfometrik tubuh pekerja T. sapiens dominan berwarna hitam dengan ukuran tubuh 3.74-4.25 mm. Abdomen dan tergite satu sampai enam berwarna hitam. Karakter morfologi dan morfometrik T. clypearis memiliki warna tubuh hitam kecoklatan dengan ukuran tubuh 2.81-3.38 mm, thorax berwarna hitam yang ditutupi oleh enam hair bands longitudinal dan masing-masing dipisahkan oleh lima glabrous yang mencolok, abdomen dan tergite pertama sampai kedua berwarna kecoklatan sedangkan tergite ketiga sampai enam berwarna hitam. Kata kunci: Lebah tak bersengat, morfologi, morfometrik, Pulau Ambon.

Abstract

This study aims to determine the effect of the adsorbents of marble powder and manure rock of laying hens on the percentage of bio-gas content, and to determine the optimization of the adsorbent treatment of manure rock of laying hens and marble powder in producing the percentage of bio-gas content and reducing the amount of bio-gas content other than CH4. The research material used was chicken manure rock and marble powder. The research method used was an experiment with RAL (completely randomized design), which consisted of 4 treatments and 4 replications. The treatment is without using adsorbents; 100% laying hen manure rock; 100% marble powder; and 50% marble powder + 50% manure rock laying hens. The variables observed in this study include the volume and time required for methane gas to flow through the adsorbent, the time required for methane gas to pass through the adsorbent to the gas-holding balloon as a sample, and the gas content in methane gas before purification, the percentage levels of CO2, CH4, O2, and N2. The results showed that the use of marble powder and manure rock adsorbents for laying hens on the percentage of biogas content gave no significant difference (P > 0.05) to the percentages of CH4, O2, and N2 gases, but gave a significant difference (P <0.05 ) to the percentage of CO2 gas of 11.33% was found in the P2 treatment which used 100% marble powder adsorbent. P2 treatment was able to reduce CO2 levels by 59.70%. It can be concluded that the greater the CH4, the better the calorific value and is inversely proportional to CO2.
