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.

Abstract

Stingless bees are one of the honey-producing groups that are currently in increasing demand. The significant rise in honey demand necessitates research into the variety of stingless bee species that have the potential to produce high-quality honey in large quantities. This study aims to determine the genetic relationship of stingless bees from two colonies in Rajabasa, Bandar Lampung. Samples were collected from two different colonies in Rajabasa, Bandar Lampung. Molecular analysis was conducted, including DNA extraction, amplification, DNA sequencing, and phylogenetic analysis using the 16S rRNA gene. The study assessed homology values, genetic distance, and the phylogenetic map. The results indicated that the individual samples, GB1 and GB2, found in Bandar Lampung, were closely related to the species Heterotrigona itama. This was confirmed by the query value of both samples being 100%, with similarity values of 96.99% and 97.20%, respectively. The genetic distance analysis, visualized in the phylogenetic map, also shows that the two samples are close relatives of Heterotrigona itama.ABSTRAK: Lebah tanpa sengat menjadi salah satu kelompok penghasil madu yang saat ini makin banyak diminati masyarakat. Peningkatan kebutuhan madu yang signifikan, memerlukan penelitian tentang ragam spesies lebah tanpa sengat yang potensial dalam menghasilkan madu yang berkualitas prima dalam jumlah yang melimpah. Penelitian ini telah dilakukan dengan tujuan untuk mengetahui kedekatan genetik lebah tanpa sengat dari dua koloni di Rajabasa, Bandar Lampung. Sampel diambil dari dua koloni yang berbeda di Rajabasa, Bandar Lampung. Analisis molekuler telah dilakukan dengan tahapan ekstraksi DNA, amplifikasi DNA, sekuensing DNA, dan dilanjutkan dengan analisis filogenetik dengan menggunakan gen 16S rRNA. Analisis dilakukan untuk mengetahui nilai homologi, jarak genetik, dan peta filogenetik. Hasil menunjukkan bahwa individu sampel GB1 dan GB2 yang ditemukan di Bandar Lampung mempunyai kedekatan dengan spesies Heterotrigona itama. Hal ini ditunjukkan dengan nilai query keduanya sebesar 100% dan nilai similarity masing-masing adalah 96,99% dan 97,20%. Analisis jarak geneti yang divisualisasi dalam peta filogenetik juga menunjukkan bahwa kedua sampel yang diperoleh merupakan kerabat dekat dari Heterotrigona itama.

Abstract

Lampung, including the Register 31 Pematang Arahan area which is next to the Bukit Barisan Selatan National Park, is known for its high biodiversity, and its coffee production. Gapoktanhut Lestari Sejahtera, consisting of 13 Forest Farmer Groups (KTH), practiced community-based forest coffee under the KPH Kotaagung Utara, Tanggamus, Lampung. To support the development of biodiversity data base for KPH Kotaagung Utara, molecular-based species identification for robusta coffee has been carried out under BLU LPPM Unila grant year 2023 and in collaboration with the Lampung Disease Investigation Center. Robusta coffee leaf samples from six KTH areas (Bumi Mulyo, Sido Makmur 1, Sido Makmur 2, Sido Makmur 3, Mandiri Jaya, and Murah Rejeki) were collected for molecular species confirmation based on the N-methyl transferase genetic marker. Molecular analysis included DNA extraction, amplification, and electrophoresis conducted at the Lampung Disease Investigation Center. Sequencing was based on the Coffea canephora CAF2 genetic marker. Bioinformatics analysis was performed using the Basic Local Alignment Search Tool (BLAST) and Molecular Evolutionary Genetics Analysis (MEGA) software version 6. Identical sequence lengths of samples in 6 KTH are varied in base pair length and nitrogen base sequences, ranging from 163-530 bp, with 5 out of 6 KTH having a genetic distance of 0.000%, while 1 sample had a genetic distance of 0.006%. It indicates that robusta coffee samples from 6 KTH areas are genetically closely related. It is supported by its phylogenetic tree, the coffee species cultivated by Gapoktanhut Lestari Sejahtera is molecularly confirmed to be robusta coffee, Coffea canephora.

Abstract

Pesawaran is one of the areas that has the potential to cultivate stingless bees as producers of honey and propolis. This study was aimed at qualitatively analysing partial amplicons of the 16S rRNA gene from individuals found at the research site. The research was performed from April to September 2023 in an explorative approach. Based on the exploration that has been done in Harapan Jaya Village, Way Ratai District, Pesawaran Regency, individual stingless bees were obtained from 5 different colonies. Individual samples of stingless bees were further extracted and amplified by commercial kits. Each individual from 5 different colonies has successfully obtained its DNA amplicons. Based on qualitative analysis using 1% agarose gel, the size of the partial gene ranged from 400bp to 500bp. This result is in accordance with the data contained in the genbank, where the 16S rRNA gene size is more than 500bp. Therefore, it has been concluded that the size of the partial amplicons of the 16S rRNA gene of individual stingless bees from the 5 colonies that were obtained is actually in range of the size of the 16S rRNA gene of stingless bees that have been recorded in the genbank.
