Abstract

Penelitian ini bertujuan untuk mengetahui perbandingan keseimbangan lingkungan dilihat dari komposisi jenis plankton, produktivitas primer, kelimpahan, indeks keanekaragaman, indeks dominansi dan indeks saprobik di Embung Potorono dan Embung Imogiri pada April dan Oktober 2021. Penelitian ini dilakukan pada bulan April 2021 sampai Juli 2022. Desain penelitian ini adalah deskriptif eksploratif. Pengambilan sampel dilakukan pada 5 stasiun dengan 5 pengulangan. Hasil penelitian menunjukkan bahwa kualitas perairan di keempat lokasi dan waktu termasuk dalam kategori tercemar ringan. Parameter yang berkontribusi terhadap kualitas air di Embung Imogiri dan Embung Potorono pada April 2021 adalah kedalaman air, curah hujan, dan suhu air yang tinggi. Curah hujan memiliki hubungan yang tidak signifikan dengan kelimpahan jenis yang tinggi namun melalui COD dapat dilihat adanya hubungan yang signifikan antara COD dengan kelimpahan jenis. Parameter yang berkontribusi terhadap kualitas air di Embung Imogiri pada Oktober 2021 adalah bahan organik, nitrat, DO, kekeruhan air dan magnesium yang cukup tinggi. Intensitas cahaya memiliki hubungan yang tidak signifikan dengan indeks dominansi fitoplankton namun nitrat, DO dan kekeruhan air memiliki hubungan yang signifikan dengan indeks dominansi fitoplankton. Parameter yang berkontribusi terhadap kualitas air di Embung Potorono pada Oktober 2021 adalah intensitas cahaya, BOD, COD, kalium dan fosfat. DO berpengaruh terhadap indeks keanekaragaman zooplankton yang dapat dilihat dari hubungan yang signifikan antara DO dengan indeks dominansi zooplankton.

Abstract

Minapadi is a term for the integrated cultivation of rice and fish. This study aimed to: (1) determine the potential of insect pests from the rice field ecosystem as a natural feed source for catfish in a Minapadi system; and (2) analyze the system's effectiveness in naturally controlling insect pest populations in rice. Three experimental plots were established: Plot A combined a rice field with acatfish pond equipped with a light trap; Plot B combined a rice field with a catfish pond without a light trap; and Plot C was a rice field alone, serving as a control. The methodology encompassed land preparation and plot layout, maintenance of rice and catfish, insect sampling, measurement of rice plant growth parameters, assessment of catfish weight and protein content, and statistical data analysis. The potential of insects as feed was indicated by the significant abundance of captured insects, categorized as either pests or natural enemies. Insect abundance across all plots increased weekly during observations. The insect pest diversity index was moderate in the integrated plots (A and B) and low in the control plot (C). The diversity index for natural enemies was moderate acrossall three plots. Statistical analysis revealed that the variation in insect pest abundance and diversity did not significantly influence the protein content levels measured in the catfish. Over all, Minapadi framework demonstrates promise as a component of integrated pest management however supplemental strategies such as light traps may be necessary to enhance control of specific pestpopulations.

Abstract

This study aims to analyze the effect of the combination of pellets and natural feed on catfish protein levels in the minapadi system. The method used was an experimental design with two feeding treatments, which were treatment A (a combination of pellets and natural feed) and treatment B (pellets only). The natural feed consisted of insects available within the minapadi system, while the pellets used were commercial pellets. The study was conducted for 76 days in the rice field area of Donotirto Village, Kapanewon Kretek, Bantul Regency, Special Region of Yogyakarta. Catfish protein content was tested using the Kjeldahl method. The data obtained was statistically analysed using an independent t-test. The average protein content of catfish in treatment A was 16.17%, whereas that in treatment B was 16.89%. The statistical analysis indicated that the combination of pellets and natural feed had no significant effect on the protein content of catfish. These results are presumably influenced by the limited availability of insects during the study, which limited their contribution as natural feed to significantly enhance the protein content of catfish. Theese finding indicates that the utilization of insects within the minapadi system requires improved management and adjustments in cultivation practices to increase their availability. Further studies are therefore necessary to explore alternative natural feed sources as well as modifications to the minapadi system that could enhance insect availability as an additional nutritional resource for catfish.
