TEMPORAL AND SPATIAL VARIATIONS OF HEAVY METALS IN SHELLFISH IN BANTEN BAY: VARIASI TEMPORAL DAN SPASIAL LOGAM BERAT PADA KERANG DAN KEPITING DI TELUK BANTEN
Get PDFBanten Bay is a busy water area with diverse activities, including capture fisheries, aquaculture, marine and land transportation, and industry, which are estimated to generate significant amounts of heavy metals that enter the water and accumulate in fish and shellfish. Some fishery commodities commonly found in Banten Bay included shellfish, such as blood cockles, green mussels, mud crabs, and blue swimming crabs. The study aims to monitor heavy metal contamination variations spatially and temporally of the shellfish in Banten Bay. Biota samples were taken for 6 months in Cengkok Coastal Waters (March–August 2019) and 3 months in Bojonegara Coastal Waters (August–October 2020). The heavy metal content was determined using an atomic absorption spectrophotometer (AAS). Pb and Cd concentrations in the flesh of the shellfish (blood cockles, green mussels, mud crabs, and blue swimming crabs) from the Cengkok and Bojonegara Coastal Waters ranged from 0.001 to 0.070 ppm and from <0.001 to 0.030 ppm, respectively. All measured heavy metal concentrations met the BPOM (2018) quality standards. Bioconcentration factors were generally <100, indicating low accumulation levels. Blood cockles, green mussels, and mud crabs from Cengkok Coastal Waters were still safe for consumption in normal amounts, while the consumption of swimming crabs was strictly limited to 0.42 kg/week for adults and 0.11 kg/week for children. The same four species from the Bojonegara Coastal Waters were also considered safe for consumption in normal portions.Perairan Pantai Teluk Banten merupakan salah satu wilayah perairan yang cukup ramai dengan aktivitas yang beragam, yang mencakup perikanan tangkap, perikanan budidaya, transportasi, dan industri, yang diperkirakan dapat menghasilkan limbah logam berat di perairan tersebut dan berakumulasi pada kerang dan kepiting. Beberapa jenis komoditas perikanan yang cukup sering ditemukan di Teluk Banten ini adalah kerang dan kepiting yang terdiri atas kerang darah, kerang hijau, kepiting, dan rajungan. Penelitian ini memiliki tujuan mengamati variasi spasial dan temporal kontaminasi logam berat pada kerang dan kepiting di Teluk Banten. Contoh biota diambil selama 6 bulan di Pantai Cengkok (Maret–Agustus 2019) dan 3 bulan di Pantai Bojonegara (Agustus–Oktober 2020). Kandungan logam berat diamati menggunakan atomic absorption spectrophotometer (AAS). Kandungan Pb dan Cd pada daging kerang dan kepiting (kerang darah dan hijau, kepiting, dan rajungan) pada perairan Pantai Cengkok dan Bojonegara, secara berturut-turut berkisar 0,001–0,070 ppm, dan <0,001-0,030 mg/kg. Kandungan logam berat tersebut memenuhi baku mutu BPOM (2018). Faktor biokonsentrasi secara umum bernilai <100, yang tergolong ke dalam kategori akumulasi rendah. Kerang darah, kerang hijau, dan kepiting bakau dari Pantai Cengkok masih aman dikonsumsi dalam jumlah yang normal, sedangkan konsumsi rajungan terbatas hanya 0,42 kg/minggu untuk orang dewasa dan 0,11 kg/minggu untuk anak-anak. Keempat biota yang sama dari Pantai Bojonegara masih aman dikonsumsi dalam porsi yang normal

Pengaruh Kualitas GCG, Ukuran Bank dan BOPO terhadap Fraud pada BPD di Sumatera Periode 2017-2024
Get PDFThis study aims to analyze the effect of Good Corporate Governance (GCG) quality, bank size, and the operating expenses to operating income ratio (BOPO) on the frequency of fraud at Regional Development Banks (BPD) in Sumatra during the 2017–2024 period. The main problem addressed is the high risk of fraud in BPDs, which threatens operational stability and public trust. This research employs a quantitative approach using secondary data obtained from annual reports and GCG self-assessment reports. Panel data regression with the Random Effect Model was used for analysis. The results show that bank size has a positive and significant effect on fraud at the 10% level (p = 0.085), while BOPO also has a positive and significant effect at the 10% level (p = 0.062). Meanwhile, GCG quality has a negative but statistically insignificant effect (p = 0.439). These findings indicate that increasing bank size and lower operational efficiency tend to elevate fraud risk, whereas improvements in GCG have not yet shown a significant impact on reducing fraud. The study highlights the importance of improving operational efficiency and strengthening oversight in large BPDs to mitigate fraud risks in regional financial institutions

Technical Study of the Drainage System Mine Dewatering at the Open Mine at PT Bukit Makmur Istindo Nikeltama
Get PDFThe high rainfall that occurred throughout 2024 caused the capacity of the existing sedimentation pond to be unable to accommodate it, resulting in water overflowing and flooding the mining area. This study aims to examine the existing drainage system using quantitative and qualitative research methods. Based on the 2014-2023 rainfall analysis, Log Pearson III distribution with a 5-year return period, the planned rainfall was 142.25 mm/day, Rain Intensity 23.31 mm/hour for a rainfall duration of 3.08 hours/day. The total discharge entering the main sump was 7,771 m3/day and was discharged through the sump outlet mouth, connected by a ditch to Settlingpond 8. At this research location, there were 3 trapezoidal ditches namely: Ditch I 1.78 m3/sec, Ditch II 1.85 m3/sec, Ditch III 2.2 m3/sec. The calculation results showed that the main sump and ditch could still accommodate the total incoming discharge. The capacity of Sedimentation Pond 8, with a volume of 7,025 m3, is not sufficient to accommodate the total inflow of 8,293 m3/second and a sedimentation rate of 40-50%. Considering that the research area cannot be expanded due to land limitations, it is necessary to increase the height by 5 meters in the three settling pond compartments to enhance sedimentation efficiency. In addition, it is necessary to add 1 Ebara 200 x 150 FS4NA pump in the last compartment to help discharge water with a total discharge of 8,293 m3/day. The benefit of this research is that it is able to provide recommendations for managing the mine drainage system.
