Abstract

Kelapa sawit atau Elaeis guineensis merupakan bagian dalam komoditas perkebunan yang memiliki prospek yang baik untuk dimanfaatkan. Prospek dari kelapa sawit ini dapat memiliki manfaat yang baik pada pangan dan non-pangan. Minyak sawit merah (red palm oil/RPO) merupakan minyak sawit yang memiliki kandungan karotenoid dan vitamin E yang tinggi, memberikan warna merah khas serta manfaat kesehatan yang potensial. Salah satu parameter kualitas minyak sawit merah adalah kadar kotoran, yaitu jumlah partikel padat atau residu yang tidak larut dalam minyak. Kadar kotoran ini berpengaruh pada kestabilan, kualitas, dan daya simpan minyak. Tujuan penelitian ini adalah untuk mengetahui kadar kotoran pada Red Palm Oil (RPO) yang diuji. Hasil pengujian kadar kotoran pada Red Palm Oil (RPO) menunjukkan kadar kotoran masing-masing sebesar 0,009%, 0,012%, dan 0,011%, yang semuanya berada di bawah batas maksimum yang ditetapkan oleh Standar Nasional Indonesia (SNI), yaitu 0,050%. Hasil uji kadar kotoran pada Red Palm Oil (RPO) yang berada di bawah batas maksimum SNI, yaitu 0,050%, menunjukkan bahwa minyak sawit merah yang diuji memiliki kualitas yang sesuai dengan standar. Kadar kotoran yang rendah ini berkontribusi pada kestabilan produk, dan memperpanjang masa simpan.

Abstract

The increase in cases of coronary heart disease without detailed knowledge of the causes is a serious problem that requires immediate treatment. This study aims to analyze the relationship between causal factors and the incidence of coronary heart disease using the Frequent Pattern Growth (FP-Growth) algorithm. This algorithm is applied to medical data of inpatients at RSUD dr. Fauziah Bireuen to identify patterns of relationships that often arise between risk factors such as age, gender, diabetes, cholesterol, hypertension and uric acid on the diagnosis of coronary heart disease. There were 180 patient medical record data with 17 items used for analysis. The results show the three most significant relationship patterns: the combination of risk factors for diabetes and high cholesterol has a support value of 50% and confidence of 67%, the risk of diabetes in men has a support value of 47% and confidence of 63%, and the combination of cholesterol and hypertension shows a support value of 45 % and confidence 66%. These results are expected to provide better insight into the prevention, early detection and treatment of coronary heart disease, as well as improving health services in hospitals. This research also emphasizes the importance of applying data mining technology in the analysis of complex health data.

Abstract

This research is motivated by the low English speaking ability of students at SMP IT Tahfizh Al Ikram Bengkalis, which hinders their participation in academic activities such as discussions and presentations. Considering the importance of affective factors—namely self-confidence, motivation, and anxiety—in the language acquisition process, this study aims to analyze the relationship between these factors and students' speaking ability. The method used is quantitative with a correlational design, involving 42 eighth-grade students selected through a purposive sampling technique. The research instruments were a standardized questionnaire and a speaking test. The results showed that there was no statistically significant relationship between students' affective factors and speaking ability, even though students' motivation and confidence were at a high level. Based on these results, it is recommended that educators prioritize efforts to reduce speaking anxiety by creating a supportive learning environment and using a variety of speaking activities. Future research is recommended to explore other variables such as linguistic competence, learning strategies, and exposure to English outside the classroom to find stronger predictive factors for speaking ability.
