Oxidative stress is caused by regular smoking. If oxidative stress is higher than the level of antioxidants, there is said to be oxidative stress. SOD, CAT and GPx enzymes in the plasma help to reduce the harm caused by oxidative stress. This study aimed to discover if smoking regularly had any impact on the enzymes found in adults. A total of 120 people, with 60 chronic smokers and 60 nonsmokers, took part in the study and each group of 60 had equal numbers of men and women. All donors of blood and plasma had their levels of SOD, CAT and GPx checked using regular spectrophotometric procedures. I carried out the analysis using SPSS software version 26.0. The levels of SOD (1.82 ± 0.29 U/mL), CAT (31.5 ± 4.8 IU/mL) and GPx (3.21 ± 0.52 IU/mL) were lower in smokers compared to non-smokers. The gender levels showed the same effect on the study results as the smoking levels and did not interact with one another. Generally, regular smoking can decrease the amount of this enzyme working in plasma, so the body becomes less able to protect itself from oxidation for both men and women. It indicates that smoking leads to a health issue and advises taking actions to decrease risks for smokers.
 

The demand for electrical energy continues to rise with the progression of time. This growth must be matched by a reliable and cost-effective supply of electricity, requiring power systems that are both dependable and economical. Since the amount of electricity consumed by users cannot be precisely predicted, balancing generation with consumption necessitates accurate electrical load forecasting. This study focuses on load forecasting using the Adaptive Neuro-Fuzzy Inference System (ANFIS) method. The forecast developed targets daily peak loads, which fall under short-term load forecasting. The data used for this forecasting consists of historical daily peak loads from January 1, 2017, to June 9, 2022. The forecasting process involves parameters such as radius, squash factor, accept ratio, reject ratio, and epoch. The forecast accuracy is evaluated using the Mean Absolute Percentage Error (MAPE) metric. The results are then compared with PLN’s load forecasting, which employs the load coefficient method. The ANFIS-based forecasting achieved a MAPE of 1.879%, using networks Jaringan_24 and Jaringan_25. This MAPE value is slightly lower than PLN’s load forecasting MAPE of 1.917%, indicating better accuracy by the ANFIS method.

Permasalahan dalam kerukunan umat beragama menjadi suatu problem yang cukup krusial, hal ini menyebabkan lahirnya pandangan-pandangan terhadap agama menjadi perhatian khusus, lahirnya pluralisme sebagai bentuk keniscayaan dalam keberagaman adat, budaya, maupun kepercayaan, yang selama ini diartikan sebagai sebuah solusi untuk mencapai kerukunan umat beragama. Firanda Andirja seorang ustad dan aktif dalam berdakwah bermanhaj Salafi ternyata menolak paham pluralisme ini,argumen-argumen penolakan beliau ini dideskripsikan dalam karya beliau tafsir Juz ‘Amma dengan menunjukan dalil-dalil yang menurut beliau merupakan pembantah paham pluralisme bahkan beliau menyebutkan pluralisme adalah paham dan aqidah yang berbahaya bagi umat Islam. Tujuan dari penelitian ini adalah ingin meninjau dan menganalisis bagaimana kontruksi pemikiran Firanda Andirja dalam memahami pluralisme, apa saja ayat yang dijadikan landasan dalam menolak pluralisme oleh Firanda, dan bagaimana makna ayat-ayat tersebut dalam kitab tafsir lain. Penelitian ini berjenis kualitatif dengan pendekatan naratif. Hasil dari penelitian ini menunjukan bahwa pemahaman pluralisme dalam tafsir Firanda yang menganggap bahwa pluralisme merupakan aqidah yang berasal dari ideologi Salafi yang beliau anut yaitu cenderung ingin memurnikan ajaran tauhid, ayat-ayat yang Firanda jadikan sebagai dalil pembantah pluralisme seperti Qs Al-Kafirun ayat 6 justru dimaknai sebagai bentuk toleransi oleh mufasir lain.
