Abstract

Nitrate and phosphate nutrients are important nutrients in waters, but in conditions that exceed the limit will cause problems for the aquatic environment. One of the aquatic environments that has the potential to experience increased nitrate and phosphate content is the DAM Estuary located in Badung, Bali. This study aims to determine the current condition of nitrate and phosphate content in water in the DAM Estuary. Water sampling was carried out at 4 different station. Station 1 represents the inlet of the DAM Estuary, Station 2 and 3 represent the middle part of the DAM Estuary, while Station 4 represents the outlet of the DAM Estuary. Nitrate was measured using Hanna HI 713 Reagent, while Phosphate was measured using Salifert Nitrate KIT Reagent. In addition, temperature, pH, TDS and DO measurements were also carried out in water. The results showed that the nitrate and phosphate content in the water in the DAM Estuary was still below the water quality standard for all classes according to Government Regulation no. 82 of 2001 concerning Water Quality Management and Water Pollution Control. Other water quality parameters also show good conditions in accordance with these regulations.

Abstract

Textile waste consists of insoluble solid particles, salts, dyes and heavy metals and is very difficult to degrade. Chitin derived from shrimp waste has the potential to overcome textile waste in chitin that causes environmental pollution through more economical absorption and easily available raw materials. Factors that improve adsorption performance include pH and temperature. This study was conducted to determine the effect of temperature, pH, and a combination of temperature and pH treatments on the ability of chitin to adsorb textile dye waste. The parameters observed were temperature, pH, combination of temperature and pH, functional groups (FTIR), chitin structure (SEM), and heavy metal test (AAS). Data analysis of statistical test results using two-way Analysis of Variance (ANOVA) followed by Duncan's further test. The ANOVA test results showed that the incubation treatment of temperature, pH, and a combination of different temperature and pH treatments resulted in (p < 0.05). This shows that incubation temperature and pH have an effect (significantly different) on the adsorption of chitin as an adsorbent on dyes. The results of Duncan's test showed that the best chitin adsorption was obtained in temperature incubation at 50°C (A3), incubation at pH 3 (B1), and the best combination adsorption at 50°C and pH 3 of 1,091±0.007a ppm.

Abstract

Perikanan tangkap di Teluk Banten didominasi oleh perikanan skala kecil, dimana intensitas penangkapan dan penggunaan alat penangkapan ikan yang tidak ramah lingkungan diduga menyebabkan degradasi daerah penangkapan ikan. Selain itu, aktivitas daratan memberikan dampak yang negatif terhadap kualitas perairan. Penelitian ini bertujuan menganalisis kualitas perairan dan intensitas penangkapan, serta menentukan tingkat degradasi daerah penangkapan ikan di perairan Teluk Banten. Pengumpulan data dilakukan dengan metode survei dan wawancara. Data kualitas perairan dianalisis secara deskriptif berdasarkan Keputusan Menteri Lingkungan Hidup Nomor 51 Tahun 2004. Data perikanan tangkap yang ramah lingkungan diambil secara langsung dan dianalisis berdasarkan kriteria Code of Conduct for Responsible Fisheries (CCRF). Status degradasi DPI ditentukan melalui pembobotan gabungan kondisi kualitas perairan dan perikanan tangkap yang ramah lingkungan. Berdasarkan hasil penelitian, kualitas perairan Teluk Banten masih dalam kondisi baik untuk kehidupan biota, walaupun parameter kecerahan dan salinitas belum sesuai dengan baku mutu air laut. Alat penangkapan ikan yang beroperasi di perairan Teluk Banten didominasi oleh jenis alat tangkap yang bersifat ramah lingkungan, seperti gillnet, pancing ulur, bagan perahu, dan bubu. Perairan Teluk Banten sudah terjadi degradasi daerah penangkapan ikan kategori ringan yaitu sekitar 58% yang diakibatkan oleh intensitas penangkapan dan penggunaan alat tangkap jaring arad. Pemanfaatan ruang laut untuk perikanan tangkap di Teluk Banten cukup tinggi sekitar 0,43 km2 untuk setiap unit penangkapan ikan.

Abstract

Penelitian ini mengevaluasi efektivitas Aqua Security untuk deteksi dan mitigasi ancaman pada lingkungan kontainer yang menjalankan aplikasi web dan modul Big Data. Arsitektur uji menggunakan Docker dan Kubernetes. Metode meliputi pemindaian image, kebijakan runtime, RBAC, dan pemeriksaan kepatuhan, disertai simulasi serangan serta analisis log. Hasil menunjukkan Aqua mampu mengidentifikasi kerentanan dan aktivitas anomali saat runtime serta memberi rekomendasi kebijakan yang mempercepat respons dan menurunkan risiko pada skenario laboratorium. Keterbatasan penelitian terletak pada skala uji dan variasi beban yang terbatas. Kesimpulannya, integrasi Aqua Security efektif sebagai lapisan deteksi dan mitigasi pada arsitektur kontainer web + Big Data, dan direkomendasikan untuk diuji lanjut pada skala produksi.
