Phytoplankton samples were analyzed using diversity index (H'), uniformity index (E), dominance index (C), and important value index (INP). The water quality parameters measured were temperature, air brightness, TDS, salinity, DO, dissolved CO2, pH, and nitrate. Statistical test analysis is t test and PCA. The results highest phytoplankton community structure in ponds near settlements, namely, Bacillariophyceae and there were 17 genera, while those far from settlements highest was Cyanophyceae and there were 11 genera. The diversity index value (H') of ponds near medium to settlements is 2.48 while ponds far from settlements is 1.8 which describes the category of phytoplankton community. The Uniformity Index (E) value ponds near settlements is 0, 242, while ponds far from settlements is 0,242 which describes the uneven distribution of phytoplankton. The value of the Dominance Index (C) which is close to the settlement is 0.274, while pond far from the settlement is 0.476, which indicates there is no dominance of a particular genus. The results of water quality parameters indicate that the condition of the shrimp pond waters is polluted because it exceeds the SNI threshold for aquaculture.Keywords: Community Structure, Phytoplankton, Shrimp PondABSTRAKFitoplankton merupakan salah satu oragnisme mikroskopis yang mempunyai peran sebagai produsen primer dan dapat dijadikan sebagai bioindikator suatu perairan, salah satunya tambak.

The uncontrolled use of pesticides has an impact on environmental pollution, especially aquatic biota such as fish. The purpose of this study was to analyze the acute concentration of the pesticide chlorpyrifos on Goldfish (Cyprinus carpio). The organism that is used as the object of this experiment is the goldfish (Cyprinus carpio) because it is considered that this type of fish has characteristics that are sensitive to all environmental change activities in the aquatic ecosystem and have fulfilled the requirements as one of the bioindicators of waters to changes in the surrounding environment. The research method is experiment with preliminary research, acute toxicity test (LC50), real test (sub lethal). The concentration of treatment in experimental animals included sublethal test K0 (control) 0 ppm, K1 0.25 ppm, K2 0.30 ppm, K3 0.35 ppm, K4 0.40 ppm, K5 0.45 ppm. The upper lethal threshold value was 0.5 ppm and the lower lethal threshold was 0.25 ppm based on the results of the preliminary test. Acute toxicity test ranges from K1 0.25 ppm to K5 0.45 ppm. The results of the acute toxicity test (LC50) at K1 0.25 ppm. There is a relationship between increased mortality of test animals with increasing concentrations of pesticides in the research media. An increase in the concentration of chlorpyrifos pesticide in the media of goldfish test animals has a very strong correlation with the number of operculum movements (opening and closing). The greater the concentration of chlorpyrifos pesticide, the faster the goldfish will experience a decrease in operculum movement.Keywords:Goldfish (Cyprinus carpio), Chlorpyrifos pesticideABSTRAK Klorpirifos digolongkan pada pestisida jenis orghanoposfat, dalam penggunaannya sering diaplikasikan pada kegiatan pertanian.

Metode penelitian dilakukan secara eksperimen menggunakan desain rancangan acak lengkap (RAL).Perlakuan konsentrasi dimulai dari 0%; 10%; 20%; 30%; 40% dengan 4 kali ulangan. Pengamatan yang dilakukan pada penelitian ini diantaranya tinggi tanaman, jumlah daun, panjang akar, bobot basah, bobot kering, dan faktor abiotik. Analisis anova digunakan dalam penelitian ini untuk mengetahui adanya perbedaan yang nyata pada setiap perlakuan kemudian dilanjut uji BNT 5%.

These polymers can produce valuable products such as fermented sugar. This study aims to study the changes that occur in delignified organic material products added with microscopic fungal cultures and different concentrations. This study used an experimental method with a mean comparison of two populations. Consisting of 2 treatments, the first A: 2.5% (11 replications) and the second B: 7.5% (11 replications), so that the total number of repetitions was 22 times. Using a consortium of Trichoderma viride, Aspergillus niger, Hansenula sp, and Candida sp. The media used in the study were Potato Dextrose Borth (PDB) media, Wang media, and papaya fruit extract. Papaya fruit extract also functions as a nutrient source for mushrooms. The pH used is pH 5. The fermentation process of the media added by delignification products of organic material with consortium fungi for 3 days (72 hours). Determination of glucose levels using the sulfuric-phenolic acid method with an ultra violet (UV) and visible light spectrophotometer. The data analysis used was the T-test. Changes that occur in delignification products of organic material when added with microscopic fungal cultures are the addition of glucose and there is a comparison of glucose levels at different concentrations. In treatment A the average glucose level obtained was 15.72375 mg / ml, while in treatment B the average glucose level obtained was 42.475 mg / ml. This proves that the two treatments were significantly different aimed at P>0.05.Keywords: Delignification, Organic Materia, Microbial Fungi (Trichoderma viride, Aspergillus niger, Hansenula sp., and Candida sp.), GlucoseABSTRAKLimbah pertanian disebut juga sebagai bahan berlignoselulosa tersusun oleh tiga polimer. Polimer tersebut dapat menghasilkan produk yang bernilai seperti gula hasil fermentasi. Penelitian ini memiliki tujuan yaitu untuk mempelajari perubahan yang terjadi pada produk delignifikasi material organik yang ditambahkan kultur jamur mikroskopis dan konsentrasi yang berbeda. Penelitian ini memakai metode eksperimental dengan desain perbandingan rerata dua populasi.

Media yang digunakan pada penelitian yaitu media Potato Dextrose Borth (PDB), media Wang, dan extrak buah pepaya. Ekstrak buah pepaya juga berfungsi sebagai sumber nutrien untuk jamur. pH yang digunakan yaitu pH 5. Proses fermentasi media yang ditambahkan produk delignifikasi material organik dengan jamur konsorsium selama 3 hari (72 jam).
