Abstract

Gamma-ray irradiation on plant seeds can affect plants’ growth and biochemical content. The application of gamma-ray irradiation can improve the quality of plants. This research aims to investigate the effect of gamma irradiation on the germination, growth, and chlorophyll content of sengon. Sengon seeds were irradiated with gamma rays at 0 (control), 25, 75, 125, and 175 Gy dose. Sengon seeds germinated and rared for four months. The study used a one-factor, completely randomized design (CRD). The parameters observed were the germination percentage, seedling height, diameter, and chlorophyll content. The result showed that gamma irradiation treatment can increase seed germination. Seeds irradiated with a dose of 75 Gy had a higher germination percentage than the other doses. Gamma irradiation with a dose of 25-175 Gy had of height and diameter of the seedlings compared to the control. Seedlings irradiated with a dose of 125 Gy had a higher chlorophyll content than other doses. Seedlings irradiated with a dose of 75 Gy had lower chlorophyll content than other doses. Therefore, in further experiment dose of gamma irradiation 25-175 Gy can be used to improve seeds’ viability. To increase the height and diameter of the seedlings, further research is still needed to investigate the effect of other doses on the growth of the seedlings.

Abstract

ampe Marta Cave Tourism is located in Kutai National Park, Kutai Kartanegara Regency, East Kalimantan, and is one of the natural tourism areas with high biodiversity. The tourist route in this area offers natural beauty and a habitat that supports the lives of various butterfly species. This study aims to identify plants that are food sources (nectar) and non-nectar, types of butterflies, and the characteristics of pollen from each food plant. This study uses the transect method, namely taking samples of flowers and butterflies along the route, and the acetolysis method to see the morphological characteristics of pollen. The results of the study showed that there were 19 species from 11 families of nectar-eating plants identified as being utilized by butterflies (imago) as a source of nectar, where Ageratum conyzoides (Asteraceae), Asystasia gangetica (Family Acanthaceae), Leea indica (Family Vitaceae) were the dominant species that were often visited. In contrast, non-nectar feed such as minerals, rotten fruit, and animal feces, where out of 14 butterfly species identified, 11 dominant species sucked minerals on the banks of rivers or mud puddles, two species visited rotten fruit, and one species was seen in animal feces. Nectar feed has the characteristics of large and round-elongated pollen, which is more efficient for sticking to the insect's body. In contrast, the round-elongated oblate shape in Oxalis barrelieri shows strategic differences in the transfer of varying pollen norms, such as echinate and scabrate. The results of this study can be a reference for butterfly researchers to provide an overview of the diversity of nectar-producing plant feed along with its morphological characteristics and non-nectar feed utilized by butterflies on the Sampe Marta Cave tourist route

Abstract

Infeksi cendawan terbawa benih merupakan salah satu faktor pembatas dalam pengembangan hutan tanaman sengon. Cendawan yang terbawa benih bisa menjadi penyebab penyakit dan dapat menurunkan produktivitas. Penelitian ini bertujuan untuk mengkaji pengaruh iradiasi sinar gama terhadap kesehatan benih sengon. Benih sengon diradiasi sinar gama dengan dosis 0, 25, 75, 125, dan 175 Gy. Uji kesehatan benih sengon dilakukan dengan menggunakan metode blotter test. Cendawan yang muncul pada benih diidentifikasi berdasarkan ciri morfologi. Hasil penelitian menunjukkan bahwa terdapat delapan jenis cendawan patogen terbawa benih yang teridentifikasi pada benih kontrol dan yang diiradiasi sinar gama, yaitu Aspergillus flavus, Aspergillus niger, Cladosporium sp., Penicillium sp., Phoma sp., Rhizopus sp., Pythium sp., dan Culvularia sp. Jenis Cladosporium sp., Penicillium sp., dan Phoma sp., mendominasi infeksi dan kontaminasi benih sengon pada setiap dosis iradiasi sinar gama. Perlakuan iradiasi sinar gama dengan dosis hingga 175 Gy belum efektif menurunkan nilai persentase infeksi cendawan terbawa benih sengon.

Abstract

Pelatihan pembuatan pupuk bokashi merupakan salah satu cara untuk mendukung urban farming dan meningkatkan nilai sampah organik di kawasan urban. Pupuk ini memanfaatkan mikroorganisme sebagai activator dalam mempercepat proses fermentasi. Tujuan dari kegiatan ini adalah untuk meningkatkan pengetahuan dan kapasitas masyarakat di kawasan urban. Kegiatan pelatihan ini melibatkan anggota kelompok Kampung KB Suwandi Mandiri sebanyak 25 peserta. Pelatihan dilakukan dengan tahapan pengisian soal pre-test, pemaparan materi, praktik, dan evaluasi dengan pengisian soal post-test. Hasil pelatihan memberikan dampak positif bagi peserta pelatihan dengan meningkatnya pengetahuan peserta dalam pembuatan pupuk bokashi. Peserta juga merasa puas dengan dilaksanakannya pelatihan pada indikator penyampaian materi yang mudah dipahami, kemudahan cara membuat pupuk bokashi, dan keinginan untuk mengaplikasikan pupuk bokashi dengan nilai setuju hingga sangat setuju
