Abstract

Penelitian ini bertujuan untuk menganalisis konsepsi peserta didik pada materi hidrokarbon. Penelitian ini merupakan penelitian deskriptif yang mendeskripsikan konsepsi peserta didik yang meliputi pemahaman konsep, miskonsepsi, dan tidak paham konsep. Populasi dalam penelitian ini berjumlah 112 siswa yang berasal dari 2 sekolah SMA yakni SMAN 1 Balaesang dan SMAN 2 Balaesang yang berlokasi di Kecamatan Balaesang Kabupaten Donggala, Provinsi Sulawesi Tengah. Pengambilan sampel menggunakan teknik sampling jenuh sehingga seluruh populasi menjadi sampel penelitian. Instrumen yang digunakan adalah tes diagnostik two tier dengan nilai validitas sebesar 0,88 dan nilai reliabilitas sebesar 0,77 dan wawancara. Hasil penelitian menunjukkan bahwa konsepsi peserta didik di SMAN 1 Balaesang untuk kategori paham konsep sebesar 64,4%, untuk kategori miskonsepsi sebesar 23,4%, dan untuk kategori tidak paham konsep sebesar 12,2%. Konsepsi peserta didik di SMAN 2 Balaesang untuk kategori paham konsep sebesar 59,9%, kategori miskonsepsi sebesar 26,1%, dan kategori tidak paham konsep sebesar 13,9%.

Abstract

Increased levels of uric acid in the blood can lead to metabolic disorders such as gouty arthritis, which require effective management. This study aimed to determine the effect of red coconut tembuluk extract (Cocos nucifera var. rubescens) on reducing uric acid levels in mice (Mus musculus). The study employed an experimental research design using a Completely Randomized Design (CRD). A total of 28 mice were used, divided into seven groups with four replications each. The groups consisted of a normal control group (KN), which received food and water ad libitum; a negative control group (K+); a positive control group (K-); and four treatment groups (PI, PII, PIII, and PIV). The negative control group (K+), positive control group (K-), and all treatment groups were induced with lard oil for 14 days to increase uric acid levels. The positive control group (K?) was treated with allopurinol at a dose of 0.026 mg per 20 g body weight. The normal control (KN) and negative control (K+) groups received food and water ad libitum without extract administration. Treatment group PI received 10% red coconut tembuluk extract, PII received 20%, PIII received 40%, and PIV received 80%. The data obtained were analyzed using Analysis of Variance (ANOVA). The results showed that administration of red coconut tembuluk extract significantly reduced uric acid levels in mice induced with lard oil. The most effective concentration in reducing uric acid levels was 80% (PIV), with an average uric acid level of 5.4 mg/dL.
