Abstract

Stingless bees are an abundant natural resource in various areas of the world. The utilisation of stingless bees is associated with their honey production. Therefore, stingless bees are widely cultivated in the community. The increasing number of cultivators also occurs in Lampung Tengah Regency. However, this increase in the number of cultivators has not been followed by research on the diversity of stingless bees, including based on their morphology. This research was implemented from May to August 2024. Explorative fieldwork was performed in Sido Mulyo, Punggur, Lampung Tengah. According to the findings of the exploration, samples were taken from seven different colonies. The samples were then observed on 11 morphological characters including (1) eyes, (2) forewings, (3) body colour, (4) thorax, (5) abdomen, (6) hammuli, (7) mesonotum, (8) mesoscutetellum, (9) propodeum, (10) hair on posterior hind tibia, and (11) elliptical disc on basitarsus. The observed samples are closest to the characteristics of species in the genus Heterotrigona (samples SK3, SK5, SK6, and SM1) and Tetragonula (samples SK1, SK2, and SK4) on the basis of morphological characters.

Abstract

Robusta coffee (Coffea canephora) genetic diversity is very important for breeding programmes aimed at increasing yield and adaptability. This diversity can be assessed through various morphological characters, especially leaf phenotype characters, which serve as indicators of genetic variation. This research was conducted from May to August 2024. Data collection was carried out by purposive sampling using the exploration and characterisation method of 30 coffee plants in the Traditional Coffee Plantation area, Bogorejo Village, Gedong Tataan District, Pesawaran Regency, Lampung Province. Qualitative character data collection was carried out modifying IPGRI descriptors. Based on the data obtained, there were no significant differences in qualitative characteristics and quantitative characteristics of leaves on 30 coffee plants. This indicates a low genetic diversity in the plantation.

Abstract

Kopi robusta (Coffea canephora) merupakan salah satu tanaman perkebunan yang umum ditanam di Indonesia karena memiliki nilai ekonomis tinggi. Kabupaten Pesawaran menjadi salah satu daerah di Lampung yang banyak mengusahatanikan kopi robusta dalam skala perkebunan rakyat. Isolasi dan amplifikasi gen menjadi langkah awal dalam analisis molekuler untuk mengetahui keragaman gen pada kopi robusta. Penelitian ini bertujuan untuk menganalisis hasil isolasi dan amplifikasi DNA daun kopi robusta dari perkebunan kopi rakyat Pesawaran, Lampung. Isolasi DNA dari 5 sampel daun kopi robusta telah dilakukan mengacu pada protokol kit isolasi DNA dari Geneaid Genomic DNA Mini Kit (Plant). Hasil ekstraksi kemudian diamplifikasi menggunakan primer N-methyltransferase dengan metode Polymerase Chain Reaction (PCR). Visualisasi hasil ekstraksi dan amplifikasi dilakukan menggunakan elektroforesis gel agarosa 1%. Visualisasi atas hasil ekstraksi telah menunjukkan diperolehnya ekstrak DNA yang baik. Visualisasi atas hasil amplifikasi menunjukkan telah diperolehnya fragmen DNA sepanjang 600bp.
