Abstract

Ageratum conyzoides, and Imperata cylindrica  are cosmopolite weeds in agricultural land that can reduce the productivity of cultivated plants. This study aims to analyze the effect of A. conyzoides  leaves biomass and I. cylindrical former plant media on the percentage of germination and growth of mung beans (Vigna radiata). The research was conducted by making 3 (three) replications of each Treatment. Treatment A (application of A. conyzoides  leaf biomass to the planting media), Treatment B (used I. cylindrica planting media), and Control Treatment. Anova test and Tukey HSD test were conducted using R-Studio. The results showed that Treatments (A) and (B) reduced the success of mung bean germination compared to the control (97%), with A at 60% and B at 50%. The changes in leaf number and root length are very noticeable compared to plant height.  The allelopathic effect was stronger in A than B. Biomass of A. conyzoides  and used media of I. cylindrica has the potential to inhibit germination and early growth of mung beans.

Abstract

Kerang lampu merupakan salah satu fauna penyusun ekosistem perairan intertidal. Kerang lampu merupakan anggota filum Brachiopoda, yang juga dikenal sebagai tauge laut. Penelitian ini bertujuan untuk mendeskripsikan fauna intertidal yang berasosiasi langsung dengan kerang lampu di perairan Kalimantan Timur. Pengambilan sampel dilakukan dengan metode purposive sampling di perairan Pantai Pendopo, Kelurahan Teritip, Kota Balikpapan, Kalimantan Timur. Pengambilan sampel dilakukan dengan menggali substrat pada area plot sedalam 5-10 cm menggunakan garpu pancing. Spesimen yang diperoleh kemudian diawetkan menggunakan alkohol 70%. Identifikasi, analisis, dan deskripsi spesimen dilakukan di Laboratorium Biosistematika Fakultas Matematika dan Ilmu Pengetahuan Alam, Universitas Lambung Mangkurat. Analisis jenis substrat (komponen substrat) dilakukan di Laboratorium Ekologi Fakultas Matematika dan Ilmu Pengetahuan Alam, Universitas Lambung Mangkurat. Hasil penelitian menunjukkan bahwa ditemukan delapan spesies fauna intertidal yang berasosiasi langsung dengan kerang lampu. Kedelapan spesies ini berasal dari enam famili yang berbeda, yaitu famili Arcidae, Veneridae, Oxudercidae, Muricidae, Balanidae, dan Holothuriidae.
