Abstract

The study of nocturnal insect diversity was conducted in Bukik Kasang, Padang Pariaman District, West Sumatra from April to May 2019. The pitfall trap was used to collect the active insect on the ground in three different habitats: open area, edge of plantation, and inside the plantation. A total 10 orders, 44 morphospecies, and 180 individual of nocturnal insect was collected. The Order Hymenoptera was the highest in number of morphospecies and individual, and in other hand, the Order Hemiptera was the lowest one. This study is very important to reveal the diversity of insect in Bukik Kasang, due to the increasing of human activities in this area and planning to develope this area as tourist destination.

Abstract

The habitat destruction and land-use changes caused the decline of animal composition in many tropical regions. Here, we study the diversity of herpetofauna in the lowland areas in Sumatera Barat, a midwestern province in Sumatera island, using a visual encounter survey method. The surveyed habitat included rubber plantations, streams, paddy fields, and peat swamps. We observed 338 individuals representing 44 species from 14 families of herpetofauna with almost 90% individuals were amphibians. Overall, the rubber plantations contained a higher number of species than other types of habitat. For amphibians, Ranidae and Dicroglossidae represented the first and the second highest both in the species and individual number. For reptiles, Agamidae and Colubridae or Gekkonidae accounted for the first and the second highest in the individual number while Colubridae and Scincidae consisted of the highest species number. Our data showed that the diversity index was mostly in moderate level except in paddy field. The species composition in rubber plantations were more similar to those of streams rather than paddy field or peat swamp Sago habitat.

Abstract

ABSTRACT. Ants are social insects that have a high diversity and wide distribution, including in mangrove forests. The existence of ant types in mangrove is influenced by human mobilization and ant migration. The ant migration naturally can occur through branches and twigs of decayed wood from mangrove trees that are drift on the ocean currents. The study to understand the distribution of ants across the islands can be done through a study of ant diversity on decayed woods in the mangrove area. This study aims to recognize the diversity of ants which is used decayed wood for nesting sites. This study was conducted in mangrove forest area of Apar Village, Pariaman city. Ants were collected by hand collecting method on every twigs, branched and decayed woods and then keep in vials filled by 70% ethanol. A total 11 species of ants that belong to 10 genera and 4 subfamilies were collected. Formicinae is the highest number of species that found in this study with 5 species, followed by Myrmicinae (3 spp.), Dolichoderinae (4 spp.), and Ponerinae (1 sp.).Keywords: Ants, Decayed woods, Diversity,  Inventory, Mangrove forestABSTRAK. Semut merupakan serangga sosial yang memiliki keanekaragaman yang tinggi dan penyebaran yang luas, termasuk di hutan mangrove. Keberadaan jenis semut di mangrove dipengaruhi oleh mobilisasi manusia dan migrasi semut. Migrasi semut secara alami dapat terjadi melalui dahan dan ranting kayu lapuk dari pohon mangrove yang hanyut terbawa arus laut. Kajian untuk memahami persebaran semut di seluruh pulau dapat dilakukan melalui studi keanekaragaman semut pada kayu lapuk di kawasan mangrove. Penelitian ini bertujuan untuk mengetahui keanekaragaman semut yang memanfaatkan kayu lapuk untuk tempat bersarang. Penelitian ini dilakukan di kawasan hutan mangrove Desa Apar Kota Pariaman. Semut dikumpulkan dengan metode pengumpulan tangan pada setiap ranting, kayu yang bercabang dan membusuk, kemudian disimpan dalam botol berisi etanol 70%. Sebanyak 11 spesies semut yang termasuk dalam 10 genera dan 4 sub famili dikumpulkan. Formicinae merupakan spesies terbanyak yang ditemukan dalam penelitian ini dengan 5 spesies, disusul Myrmicinae (3 spp.), Dolichoderinae (4 spp.), dan Ponerinae (1 sp.). Kata kunci: Semut, Kayu lapuk, Keanekaragaman, Inventarisasi, Hutan Mangrove

Abstract

The ants are one of the insects that dominate all ecosystems, it biomass reaching more than 30% in tropical ecosystems. The ants plays positive or negative roles in ecosystem. The negative role of ants is as a household pests that can have a negative impact on humans. The loss caused by pest ants is causing contamination of food as well as contamination of sterile equipment in hospitals and laboratories. The ant stinging will cause allergies and also become disease vectors due they association with several pathogenic microorganisms. This study was conducted at the Biology Laboratory, Faculty of Mathematics and Natural Sciences, Universitas Negeri Padang, Air Tawar, West Sumatra, from October to November 2021. The ants were collected inside and outside of the laboratory by using the baited trap (peanut butter, honey, and sardines) and hand collection methods. A total of 419 individual ants were found belonging to eight species and three subfamilies. The highest number of individual found in Tapinoma melanocephalum.

Abstract

Anak usia sekolah memerlukan asupan energi dan zat gizi untuk mendukung pertumbuhan dan juga prestasi belajar anak di sekolah. Salah satu sumber asupan energi dan zat gizi bagi anak sekolah bersumber dari pangan jajanan. Anak usia sekolah sebagai generasi penerus bangsa merupakan investasi bagi suatu bangsa. Kualitas anak-anak pada masa sekarang akan menentukan kualitas suatu negara di masa depan. Edukasi keamanan pangan jajanan perlu dilakukan sejak dini secara sistematis dan juga berkelanjutan sebagai salah satu upaya untuk peningkatan kualitas sumber daya manusia. Pemberian nutrisi yang berkualitas, sehat dan sesuai dengan kuantitas yang seharusnya penting untuk menunjang pertumbuhan perkembangan anak usia sekolah agar optimal. Oleh karena itu, perlu adanya edukasi kepada siswa SD untuk meningkatkan pengetahuan terkait keamanan pangan jajanan dan mengetahui arti simbol-simbol pada bungkus jajanan. Kegiatan ini dilaksanakan pada bulan Juli 2022, dan diikuti oleh 206 peserta dari kelas 3 dan 6 SDN 02 Payakumbuh. Hasil evaluasi kegiatan menunjukkan adanya peningkatan pengetahuan siswa terhadap keamananan jajanan dan memiliki keterampilan dalam mengidentifikasi simbol-simbol pada bungkus jajanan. Kesimpulan untuk kegiatan ini sudah efektif dilaksanakan dan dapat mengedukasi siswa SD dalam  mengetahui keamanan pangan jajanan.

Abstract

Changing the function of habitat into a tourism area will have an impact on the diversity of Anuran species. This condition is currently happening in the Talago Nagari Paninjauan Waterfall Area, Tanjung Raya District, Agam Regency, West Sumatra. This study is therefore important for revealing the diversity of Anuran species before the impact to this habitat increase in the future. This study used the VES (Visual Encounter Survey) sampling technique, and information on various localities and the microhabitat of each species was recorded. A total 48 individuals, with 12 species belonging to six families of Anuran was collected. Species diversity in the Talago Waterfall area shows a medium level of diversity, with an index of 2.2653, a medium species richness index of 2.8414. In this area, no dominant species were found with a low dominance index (0.1207). If the level of tourism activity in the Talago Waterfall area increases, it will have an effect in the future by causing habitat disruption and the presence of Anura; thus, related parties must be able to take appropriate action on tourism activities in the area.

Abstract

Pengamatan kromosom merupakan salah satu langkah yang dapat dilakukan agar mendapatkan infromasi dasar mengenai genetik. Informasi mengenai kromosom sangat membantu untuk melihat hubungan kekerabatan, pengungkapan variasi, dan upaya untuk melestarikan suatu spesies. Penelitian pada kromosom ikan air tawar telah banyak dilakukan di Indonesia. Namun penelitian terdahulu yang dilakukan hanya terfokus pada jenis ikan tertentu saja tanpa memperlihatkan perbandingan jumlah dan karyotipe dari masing-masing kromosom ikan air tawar tersebut. Metode yang digunakan adalah studi literatur dari berbagai penelitian terkait kromosom ikan air tawar yang ada di Indonesia. Tujuan dari penelitian ini adalah untuk melihat perbedaan jumlah dan karyotipe masing-masing kromosom pada ikan air tawar. Dari hasil analisa diperoleh jumlah kromosom ikan yang bervariasi mulai dari 36 – 98 kromosom. Selain memiliki jumlah kromosom yang berbeda, juga terdapat perbedaan bentuk ataupun karyotipe kromosom dari masing-masing ikan air tawar. Data hasil penelitian dapat digunakan sebagai bahan referensi untuk melihat perbandingan dari jumlah dan karyotipe dari masing-masing kromosom ikan.
