Logam biasanya dilapisi dengan pelapis epoksi resin seperti bisfenol A (BPA). BPA dapat mempengaruhi sistem endokrin dan dapat menyebabkan kerusakan pada berbagai jaringan serta organ. Penelitian ini bertujuan untuk mengetahui kandungan migrasi BPA pada kemasan kaleng sarden dan kornet serta paparannya pada penduduk Indonesia. Sampel yang digunakan adalah kemasan kaleng kosong untuk sarden dan kornet masing-masing 12 buah kemudian dianalisis menggunakan HPLC-UV Vis. Hasilnya menunjukkan bahwa konsetrasi migrasi BPA dalam kemasan kaleng sarden (menggunakan simulan etanol 20%) berkisar antara 0,005 – 0,05 mg/kg. Sedangkan dalam kemasan kaleng kornet (menggunakan simulan etanol 10%) sebesar 0,005 mg/kg. Rerata estimasi paparan perhari migrasi BPA dari konsumsi sarden dalam kaleng tertinggi terdapat pada usia 24-59 bulan yaitu 0,0546 µg/kgBB, sedangkan estimasi paparan perhari migrasi BPA dari konsumsi kornet dalam kaleng tertinggi terdapat pada usia anak 5-12 tahun yaitu sebesar 0,0066 µg/kgBB. Nilai risiko P95 untuk paparan migrasi BPA dari konsumsi sarden dalam kaleng pada seluruh kelompok usia sebesar 2,3883% sedangkan nilai risiko paparan dari konsumsi kornet dalam kaleng pada seluruh kelompok usia sebesar 0,3846%. Nilai risiko tersebut tidak melebihi asupan harian yang dapat ditoleransi sementara (tTDI), yang mengindikasikan bahwa paparan migrasi BPA melalui kemasan kaleng sarden dan kornet akibat mengkonsumsi sarden dan kornet tidak menimbulkan risiko bahaya terhadap kesehatan manusia di Indonesia.","PeriodicalId":34810,"journal":{"name":"Jurnal Keteknikan Pertanian Tropis dan Biosistem","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136024308","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To cope with those problems, melon was cultivated inside the greenhouse. However, there are several parameters influenced to melon quality inside the tropical greenhouse with hydroponic system. There were a few studies on the prediction model development of melon inside the greenhouse in a tropical area, Indonesia. The aim of this study was to develop an artificial neural networks (ANNs) model to predict the melon production inside the greenhouse (fruit weight) using several parameters such as the number of days to fruit formation, number of days to maturity, plant length, fruit width, fruit length, fruit cavity diameter, flesh diameter, branch number, fruit branch number, and leaf number. The result of this study was the ANN model with configurations of 10 input layers, 6 hidden layers, and 1 output layer with R2 was 0.93.

The aeroponic method has a faster nutrient delivery speed than hydroponics and normal plant cultivation. The main objective of this study was to design an aeroponic monitoring and control system for Pakcoy (Brassica rapa. L) using the blynk application as an interface for remote control. The control system used is NodeMCU V3, DHT22 sensor, HC-SR04 ultrasonic sensor and TDS sensor. Plants in the system use a container box measuring 110 cm x 80 cm with 10 nozzles on the inside of the box attached to a ½ inch pipe, with 24 planting holes on the lid of the box with a spacing of 20 cm. The pump will automatically turn on when the temperature in the box is >25oC and will stop when the temperature is =24oC, or when the humidity is <80%. The results obtained during the 30 days of research showed that the average R2 value of the DHT22 sensor was 0.9864 and 0.9864, the HC-SR04 sensor was 0.996 and the TDS sensor was 0.9899. Observations on the growth of pakcoy plants obtained an average height of 13.3 cm for system plants and 13.4 cm for control plants. The average leaf width in system plants was 4.3 cm and 3.6 cm in control plants. the average number of leaves on system plants is 8 leaves and 9 leaves on control plants. The system plant weight was 5.493 gr and that of the control plant was 2.961 gr. The control system that has been made can work well and can be used in aeroponic cultivation of plants.   ","PeriodicalId":34810,"journal":{"name":"Jurnal Keteknikan Pertanian Tropis dan Biosistem","volume":"2013 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135453008","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
