Abstract

Research of Analysis of Weeds in Rice Plantations (Oryza sativa) was conducted in April - June 2025, located in Wanasari Village, Semendawai Timur District, East OKU Regency. The purpose of the study was to analyze weed vegetation in rice plantations (Oryza sativa). This study uses survey methods. Sampling using on the plot which is carried out based on a rectangular plot measuring 2 m x 2 m with a total of 5 plots is placed systematically. The results of the study found 9 species from 7 genera and 7 families. The nine species are Scoparia dulcis, Ophiopogon japonicus, Ludwigia peploides, Ludwugia octovalvis, Ageratum conyzoides, Fimbristilys littoralis, Cyperus kyllingia, Cynodon dactylon, and Sida rhombifolia. The highest weed density calculation was in the Cynodon dactylon species with a value of 7.8 ind/m2 and the lowest in the Scoporia dulcius species with a value of 2.65 ind/m2. The highest important value index (INP) was Cynodon dactylon with an important value index value of 25.73%. While the lowest important value index was the Scoparia dulcis weed type with an important value index of 16.08%. Diversity index is included in the moderate category with a value of  2,13.

Abstract

Penelitian di Sungai Tanjung Rambang Kota Prabumulih. Penelitian ini bertujuan mengkaji status mutu air fisik dan kimia pada tata guna lahan permukiman penduduk dan hutan alami. Pengambilan sampel dilakukan menggunakan metode purposive sampling di dua stasiun pengamatan. Hasil analisis menunjukkan bahwa seluruh parameter fisik suhu, TSS, dan kekeruhan pada kedua stasiun masih memenuhi Baku Mutu Air Sungai Kelas II berdasarkan PP No. 22 Tahun 2021. Sebaliknya, parameter kimia air mulai terdegradasi nilai pH di Stasiun 1 5,56 dan Stasiun 2 5,86 tidak memenuhi standar Kelas II (rentang 6–9) karena cenderung asam. Meskipun BOD tergolong rendah < 3 mg/L, konsentrasi COD di Stasiun 2 24,5 mg/L telah mendekati batas maksimum 25 mg/L. Secara keseluruhan, kondisi fisik sungai masih sangat baik, tetapi karakteristik kimiawi air mulai menurun secara spesifik pada indikator derajat keasaman pH.
