Abstract

Penelitian ini bertujuan untuk mengidentifikasi serangga penyerbuk pada tanaman kopi (Coffea arabica L.). Penelitian ini dilakukan dari bulan April hingga September 2016 di Kabupaten Dairi. Sampling dilakukan pada enam lokasi yang tersebar pada tiga Kecamatan yaitu Sumbul, Parbuluan, dan Siempat Nempu Hulu. Masing-masing lokasi terdiri dari lima plot, setiap plot berukuran 7 x 7 meter. Sampling dilakukan ketika hari cerah pada pukul 07.00 hingga 12.00 WIB. Serangga yang berhasil ditangkap dimasukkan ke dalam killing bottle yang mengandung etil asetat. Selanjutnya dimasukkan ke dalam kertas papilot dan disimpan ke dalam box plastik untuk kemudian diidentifikasi. Identifikasi dilakukan di Laboratorium Biosistematika Jurusan Biologi Universitas Negeri Medan. Berdasarkan hasil identifikasi diperoleh sebanyak lima belas spesies yang termasuk dalam tiga Ordo, yaitu Lepidoptera Diptera, dan Hymenoptera serta tujuh famili. Lebah madu Apis cerana merupakan spesies yang paling banyak ditemukan. Kata kunci:  Serangga penyerbuk, Kopi, Apis cerana, Diptera, Hymenoptera, Lepidotera

Abstract

Coffee is one of the export commodities of the State of Indonesia, a foreign exchange earner besides oil and gas so that it has an important role in economic activities in Indonesia. The main problem with smallholder coffee plantations is the low productivity and quality to meet export standards. One of the causes is pest attack which also causes economic loss. The coffee berry borer (Hypothenemus hampei Ferrari) is one of the main causes of the decline in coffee production in Indonesia, even in all coffee-producing countries in the world. The purpose of this study was to analyze the attack intensity of the coffee berry borer (H. hampei) on Coffea arabica and Coffea canephora plants in North Sumatra. The research was conducted in Karo, Dairi, Samosir, Humbahas, Taput, Tapsel, Toba, and Simalungun districts spread over fifteen locations. Sampling in this study was carried out exploratively with the Random Sampling method. The results showed that the highest attack intensity of H. hampei on C. arabica was at Paranjulu (56 %) with an altitude of 949 mdpl; and on C. canephora was at Marihat Huta (62 %) with an altitude of 898 mdpl. Huta Galung in Samosir district with an altitude of 1759 mdpl did not find attack intensity H. hampei. The conclusion showed that altitude affected the attack intensity of H. hampei

Abstract

Hypothenemus hampei Ferrari, 1867, is a globally significant pest of coffee (Coffea spp.). Genetic information about H. hampei from various locations, including countries in America, Africa, and Asia (Java, Indonesia), is available. However, the data has yet to be available for Sumatra. This research aims to study the genetic population of H. hampei in coffee plants in Sumatra. In this study, a total of 27 mitochondrial cytochrome oxidase subunit 1 (COI) gene sequences were used to estimate the population genetics of H. hampei in Sumatra, collected from C. arabica, C. canephora, and C. liberica at nine locations. The analysis of the COI gene sequences revealed that they contained 236 base pairs (53.76%) of conserved sites, 203 base pairs (46.24%) of variable sites, 153 base pairs (34.85%) of parsimony sites, and 50 base pairs (11.38%) of informative single sites out of a total of 439 base pairs. Haplotype analysis of the COI gene in H. hampei from Sumatra revealed 10 haplotypes, with a haplotype diversity (h) of 0.649 and nucleotide diversity (π) of 0.004. Genetic differentiation (Fst) of H. hampei is low among populations in Sumatra. Genetic variation within populations is higher, and between populations is low. The genetic distance of 0-0.28%, 27 H. hampei sequences from Sumatra are in the same branch, indicating low genetic variation. This information holds great potential for designing sustainable control strategies to manage this pest species in coffee plants, particularly in the Sumatra region.

Abstract

Kegiatan Pengabdian Masyarakat oleh tim dosen pengabdian masyarakat FMIPA Universitas Negeri Medan ini peningkatan kompetensi guru SMP dalam menerapkan pembelajaran IPA terpadu berbasis masalah. Pembelajaran IPA terpadu berbasis masalah dapat meningkatkan literasi sains siswa. Tujuan pengabdian mengacu pada permasalahan dan analisa situasi pada mitra. Adapun masalah yang dihadapi mitra adalah 1) Proses belajar mengajar masih sangat berfokus pada guru (teacher centered) sebagai sumber utama informasi atau pengetahuan. 2) Media pembelajaran IPA yang kurang optimal dalam meningkatkan literasi sains siswa dan berpikir kritis. 3) Kurangnya kompetensi guru SMP dalam menerapkan pembelajaran IPA terpadu berbasis masalah Pembelajaran IPA yang diterapkan di SMP/MTs saat ini dikemas secara terpadu. Dengan demikian, dalam pembelajaran IPA Terpadu siswa dapat memperoleh pengalaman belajar secara langsung dalam menemukan sendiri konsep yang dipelajari. Pendampingan ini diharapkan dapat meningkatkan kompetensi guru dalam pengembangan pembelajaran, sekaligus meningkatkan keterlibatan dan berpikir kritis siswa dalam pembelajaran

Abstract

Background: Rousettus amplexicaudatus is widely distributed across Indonesia, including the Suruman Cave in South Bengkulu. Due to similarities in morphology within the Rousettus group, identification can be challenging. We conducted a molecular analysis using COI and Cytochrome b genes from mitochondrial DNA to explore its genetic traits. DNA was extracted from the blood tissue of seven individuals from the Suruman Cave population, and gene amplification was performed with 20 bp primers. Sequence data were analyzed using MEGA XI software. Results: As a result, characteristics of the COI gene, which is 897 bp in length, were characterized by a high frequency of base pairs Adenine-Thymine (55.5%) and Guanine-Cytosine (44.5%), with the majority of the DNA sequence exhibiting a high degree of conservation sites (97.8%). The average intrapopulation genetic distance based on the COI gene was 0.77%, with four specific sites for R. amplexicaudatus Suruman Cave. The Cytochrome b gene, which is 635 bp long, is characterized by Adenine-Thymine base pairs of 53.7% and Guanine-Cytosine of 46.3%. Cytochrome b is more conserved than the COI (99.1%). The average intrapopulation genetic distance based on the Cytochrome b gene is 0.3% and has no population-specific sites. Conclusions: Both sequences showed a consistent pattern in phylogenetic tree analysis, which suggests the Suruman population is the group of R. amplexicaudatus. Therefore, these sequences can be proposed as molecular markers for R. amplexicaudatus, particularly when compared to the whole sequences of the COI and cytochrome b.
