Abstract

Sungai Gandong merupakan sungai yang melalui Kabupaten Bojonegoro dengan panjang 45 km. Salah satu sumber air Sungai Gandong berada di Sumber Air “Growgoland” Kecamatan Dander. Penelitian dilakukan untuk menelaah beberapa parameter kualitas air di 6 titik Sungai Gandong ruas Kecamatan Dander sehingga dapat diketahui kondisi dan tingkat status mutu airnya. Parameter yang dianalisis yaitu pH, DO, BOD, COD, TSS, dan nitrat. Status mutu air dianalisis dengan Metode Indeks Pencemaran (IP) yang berpedoman pada Keputusan Menteri Lingkungan Hidup No. 115 Tahun 2003 tentang Pedoman Penetapan Status Kualitas Air. Setelah dianalisis diperoleh Indeks Pencemaran (IP) ≤ 1 yang berarti sungai dalam kondisi baik. Nilai Indeks Pencemaran (Ip) terendah 0.527 di tiitk 0 dan tertinggi 0.907 di titik 3 Sungai Gandong.

Abstract

The low level of students' critical thinking skills negatively impacts the Literacy Development Index. Critical thinking is a solution for developing literacy skills; in other words, if students possess strong critical thinking abilities, the Literacy Index will improve. This study aims to analyze the effect of intensive reading activities using expository texts on students' critical thinking skills. This research employs a quantitative approach with a true experimental design, specifically a pretest-posttest control group design. Data collection methods include observation and tests, analyzed using SPSS version 27. The research was conducted at Madrasah Ibtidaiyah Negeri 2, Bogor Regency, with a sample size of 47 students. The analysis conducted includes: 1) descriptive analysis, which describes research variables through percentages, and 2) t-test to statistically compare the two groups. The results indicate that the experimental group achieved a higher percentage of critical thinking skills than the control group. The post-test scores of the experimental group were significantly higher, demonstrating a positive impact and significant improvement in students' critical thinking skills facilitated by intensive reading techniques using expository texts. This study concludes that learning activities utilizing intensive reading techniques effectively enhance students' critical thinking skills. Consequently, improving students' critical thinking skills will contribute to advancements in the Literacy Development Index.

Abstract

Daun delima (Punica granatum L.) secara tradisional telah banyak digunakan untuk berbagai penyakit salah satunya untuk demam. Berbagai senyawa terdapat dalam daun delima yaitu flavonoid, tanin dan saponin, dimana senyawa flavonoid berfungsi sebagai antipiretik. Metode penelitian ini Eksperimental Laboratorium. Penelitian ini bertujuan untuk mengetahui efektivitas antipiretik dan dosis efektif ekstrak etanol daun delima pada penurunan suhu mencit. Metode penelitian yang digunakan adalah eksperimental laboratorium. Sebanyak 25 ekor dengan berat badan 20- 30 gram dibagi menjadi 5 kelompok perlakuan yang terdiri dari kelompok perlakuan kontrol negatif diberikan na-CMC 0,5%, perlakuan positif diberikan paracetamol dan 3 kelompok perlakuan dengan pemberian ekstrak daun delima dosis bertingkat yaitu 100 mg/g BB, 150 mg/g BB, 200 mg/g BB. Untuk menaikkan suhu rektal, mencit diberikan suspensi pepton 5% secara oral kemudian diukur dengan menggunakan termometer digital setiap 30 menit hingga menit ke 120. Data hasil penelitian dianalisis dengan program SPSS yang dianalisis menggunakan uji ANOVA (Analysis Of Varian) dengan hasil penelitian menunjukkan bahwa daun delima memiliki efektivitas antipiretik. Data yang dihasilkan berdistribusi normal (p>0,05). ekstrak etanol daun delima yang paling efektif sebagai antipiretik yaitu pada dosis 150 mg dan 200 mg/g BB. Kesimpulan penelitian daun delima memiliki aktivitas antipiretik.Kata kunci : Daun Delima, Antipiretik, PeptonPunica granatum L. have traditionally been used for various diseases, one of which is fever. Various compounds are found in pomegranate leaves, namely flavonoids, tannins and saponins, where flavonoid compounds function as antipyretics. This research method is Experimental Laboratory. This study aims to determine the effectiveness of antipyretics and effective doses of ethanol extract of pomegranate leaves in reducing the temperature of mice. The research method used is laboratory experimental. This study aims to determine the effectiveness of antipyretics and effective doses of ethanol extract of pomegranate leaves in reducing the temperature of mice. The research method used is laboratory experimental. Twenty five individuals weighing 20-30 grams were divided into 5 treatment groups consisting of a negative control group given 0.5% na-CMC, positive treatment given paracetamol and 3 treatment groups with graded doses of pomegranate leaf extract, namely 100 mg/day. g BW, 150 mg/g BW, 200 mg/g BW. To raise the rectal temperature, the mice were given orally 5% peptone suspension and then measured using a digital thermometer every 30 minutes until the 120th minute. Pomegranate has antipyretic effectiveness. The resulting data is normally distributed (p>0.05). The most effective ethanol extract of pomegranate leaves as an antipyretic is at doses of 150 mg and 200 mg/g BW. The conclusion of this study is that pomegranate leaves have antipyretic activity.Keywords : Punica granatum, Antipyretic, Pepton
