Abstract

Permasalahan yang sering dihadapi dalam industri akuakultur adalah tingginya biaya yang terkait dengan pakan ikan. Pakan merupakan faktor penting yang memengaruhi pertumbuhan dan kelangsungan hidup ikan yang dibudidayakan. Salah satu metode potensial untuk meningkatkan pertumbuhan ikan adalah dengan memasukkan ragi ke dalam pakan mereka. Dalam penelitian ini, digunakan Rancangan Acak Lengkap (RAL) yang terdiri dari empat perlakuan berbeda dengan tiga kali pengulangan. Perlakuan-perlakuan ini dilambangkan sebagai berikut: Perlakuan A (0 ml ragi alami per kilogram pakan), Perlakuan B (10 ml ragi alami per kilogram pakan), Perlakuan C (20 ml ragi alami per kilogram pakan), dan Perlakuan D (30 ml ragi alami per kilogram pakan). Pemberian pakan dilakukan dua kali sehari, dengan dosis pakan setara dengan 5% dari berat badan ikan. Hasil penelitian menunjukkan bahwa pemberian ragi alami yang berasal dari ekstrak buah mentimun ke dalam pakan tidak memberikan pengaruh yang signifikan terhadap parameter bioekologi ikan nila salin. Oleh karena itu, disarankan agar penelitian selanjutnya memperpanjang periode penelitian untuk memastikan efek sebenarnya dari perlakuan dan melakukan analisis uji proksimat untuk mengetahui kandungan protein dalam pakan.

Abstract

Sungai merupakan salah satu sumber kehidupan bagi masyarakat yang tinggal di daerah perkotaan. Banyaknya permukiman di sepanjang sungai sangat memengaruhi kualitas air dari sungai. Penurunan kualitas air ditandai dengan perubahan warna air, bau, dan adanya bakteri Coliform fecal (E. coli). Penelitian ini bertujuan untuk menganalisis kualitas air sungai Sekanak berdasarkan faktor fisika, kimia, dan mikrobiologi. Uji laboratorium yang dilakukan untuk mengetahui keberadaan bakteri Coliform yang merupakan indikator pathogen dalam air. Pengambilan sampel air menggunakan metode purposive sampling, dan uji laboratorium dengan menggunakan metode Most Probable Number (MPN). Hasil analisis mikrobiologi pada sampel air sungai sekanak 1-12 menunjukkan nilai indeks 1100/100 mL, 460/100 mL, 240/100 mL, 75/100 mL, 75/100 mL, 1100/100 mL, 64/100 mL, 1100/100 mL, 1100/100 mL, 1100/100 mL, 1100/100 mL, 2400/100 mL. 12 sampel uji menunjukkan hasil yang tidak memenuhi syarat nilai cemaran Coliform fecal (E. coli) sesuai surat keputusan menteri kesehatan Republik Indonesia Nomor 907 / MENKES / Sk / VII / 2002 menyatakan bahwa air minum harus memenuhi persyaratan dengan tingkat kontaminasi 0/100 mL untuk keberadaan Coliform. Data parameter fisika yang meliputi suhu, dan kekeruhan air, serta parameter kimia berupa pH menunjukkan hasil yang lebih besar dibandingkan baku mutu air sungai pada Peraturan Perundangan Republik Indonesia No.22 Tahun 2021 tentang penyelenggaraan perlindungan dan pengelolaan lingkungan hidup. Hal ini menunjukkan bahwa air sungai tidak memenuhi syarat untuk kebutuhan higiene sanitasi.

Abstract

Practical activities are a learning method that can involve students in constructing their own understanding. A good practicum activity must be guided by a structured instruction sheet or student worksheet that is able to lead students to understanding. The purpose of this research is to produce a worksheet for students of osmosis practicum that is reconstructed using Vee diagrams. The method used in this research is descriptive qualitative method. The results of this study indicate that the LKPD of osmosis practicum that has been analyzed has deficiencies in the purpose or focus of the question made, besides that there are still deficiencies in procedures and data transformation so that it does not lead to the desired conclusion. Reconstruction was carried out using Vee diagrams so that the resulting LKPD for osmosis practicum had all the criteria for the Vee diagram assessment score. Based on the results of the scores obtained on the reconstructed osmosis practicum LKPD, it shows that the LKPD is feasible and can be used in guiding students in osmosis practicum activities. From the results of the reconstruction carried out, it is hoped that the reconstructed products using Vee diagrams can guide students in constructing their own understanding. In addition, in the future, the reconstruction of LKPD using Vee diagrams can be further developed.

Abstract

Linear Alkylbenzene Sulfonate (LAS) is an anionic surfactant with the potential to cause environmental pollution. One effective bioremediation strategy to mitigate this pollution is the use of endophytic bacteria. This study aims to evaluate the resistance ability of endophytic bacteria isolated from the roots of water hyacinth against LAS. The research was conducted as a laboratory-based experimental study using a Completely Randomized Design with five replications for each isolated endophytic bacterium. Bacterial resistance to LAS was tested in a liquid medium containing 10 ppm LAS and incubated for 14 days. The resistance level was determined based on the bacterial optical density (OD) measured using UV-VIS spectrophotometry. The results identified four endophytic bacterial isolates belonging to the genera Bacillus, Streptomyces, Micrococcus, and Neisseria, all of which exhibited resistance to LAS. The highest resistance level was observed in Streptomyces with an average OD value of 0.728 ± 0.11, while the lowest resistance was found in Bacillus with an average OD value of 0.361 ± 0.04.

Abstract

Gastropods act as environmental bioindicators because they are sensitive to changes in the aquatic environment. The purpose of this study was to determine the diversity of gastropod species on Muko Wujo Beach. Determination of sampling points using the purposive sampling method. Samples were taken at two different stations based on human activities. The stages in collecting data on gastropod species include observing gastropods found in a 1x1 m plot, counting the number, and then recording it for identification purposes. In addition, environmental parameters, namely temperature and pH, were measured. Data on gastropod species and environmental parameters were then analysed qualitatively and quantitatively. Qualitative analysis was carried out by describing the morphological characteristics of gastropods, and identification was carried out using the help of scientific articles and internet websites. Quantitative analysis was carried out by calculating the diversity index, dominance index and similarity index of gastropod species. The results showed that 29 types of gastropods were found on Muko Beach, Larantuka District, East Flores Regency, which were divided into 14 families and 7 Orders. The diversity index, dominance index, and similarity index of gastropod species on Muko Wujo Beach were classified as moderate.

Abstract

Rapid development and increasing population growth affect river water quality, including the Ciliwung River. The decline in the water quality of the Ciliwung River is caused by organic waste originating from households, industry, livestock, and agriculture, so efforts are being made to manage the water using phytoremediation. Pistia stratiotes and Salvinia molesta are aquatic plants that can absorb heavy metals in polluted water. This research aims to determine the effectiveness of plants Pistia stratiotes and Salvinia molesta in reducing the Ciliwung River's wastewater level. This type of research is laboratory-scale experimental with RAL in 3 treatments (A, B, and C) and 6 replications. Data were analyzed using the ANOVA test with the DMRT further test. The results of the research showed that the treatment of two types of plants had a significant effect on reducing the level of water turbidity with the greatest reduction rate being found in plants Salvinia molesta. The fastest change in color and reduction in the number of leaves occurs in plants Pistia stratiotes, and the levels of AAS contaminants before and after treatment cannot be detected because the detection limit of the smallest limit test parameter possessed by a tool/instrument for measuring a certain number of analytes is different.

Abstract

Kebon Gedang Block is one of the few areas of natural dye batik craftsmen in Indonesia. The activity of using natural dyes for batik has been carried out from generation to generation. This study aims to analyze the transfer of ethnobotanical knowledge of natural dyes based on age class (KU), analyze ways to regenerate and analyze the policy scheme for retention of ethnobotanical knowledge of natural dyes in the Kebon Gedang Block. The main methods used in this study were semi-open interviews, observation, and documentation. The selection of respondents was carried out by purposive sampling by considering age (years), namely I (30-39), II (40-49), III (50-59), IV (> 60). The results showed that the level of knowledge of natural dyes and retention was highest in KU III because the people were still healthy, strong, and generally still actively following the development of the batik industry. However, KU III is the group with the highest change in knowledge and is feared to be lost. While at other KU levels, the inheritance of knowledge is still going well. The policy of retaining ethnobotanical knowledge of natural dyes can be carried out in several ways, including by creating books, booklet or electronic sites about knowledge of natural dyes, as well as by registering intellectual property rights. This research can record the current state of knowledge so that efforts can be made to avoid losing this knowledge.
