Authors: Hidayati Dian Chusnul , Al Faraby Said , Adiwijaya Adiwijaya
Published: February 2020

Hadith is the second source of Islamic law after Al-Quran, making it important to study. However, there are some difficulties in learning hadith, such as to determine which hadith belongs to the topic of suggestions, prohibitions, and information. This certainly obstructs the hadith learning process, especially for Muslims. Therefore, it is necessary to classify hadiths into the topic of suggestions, prohibitions, information, and a combination of the three topics which also called as multi-label topic. The classification can be done with the K-Nearest Neighbor, it is one of the best methods in the Vector Space Model and is the simplest but quite effective method. However, the KNN has a lack in dealing with high vector dimension, resulting in the long time computing classification. For that reason, it is necessary to classify Sahih Bukhari's Hadiths into the topic of recommendations, prohibitions, and information using the Latent-Semantic Analysis - K-nearest Neighbor (LSA-KNN) method. Binary Relevance method is also employed in this research to process the multi-label data. This research shows that the performance of LSA-KNN is 90.28% with the computation time is 19 minutes 21 seconds and the performance of KNN is 90.23% with the computation time is 37 minutes 06 seconds, which means that the LSA-KNN method has a better performance than KNN

Diarrhoegenic E. coli (DEC) merupakan kelompok strain E. coli patogenik yang diketahui menjadi salah satu penyebab penyakit diare. Kasus diare masih cukup tinggi di negara-negara yang sedang berkembang seperti Indonesia. Di Kabupaten Tanah Bumbu Kalimantan Selatan khususnya di wilayah kerja Puskesmas Batulicin dan Pagatan memiliki angka kasus diare yang masih fluktuatif. Penelitian ini bertujuan mendeteksi DEC pada sampel feses penderita diare di wilayah kerja Puskesmas Batulicin dan Pagatan dengan pemeriksaan PCR. Desain penelitian Cross Sectional dengan jumlah sampel feses sebanyak 15, dikumpulkan selama 3 bulan (Agustus - Oktober 2018). Sampel feses diperiksa menggunakan PCR untuk mendeteksi keberadaan strain DEC yakni EAEC, ETEC, dan EPEC serta EHEC. Tiga dari lima belas (20%) sampel diketahui positif DEC. Strain ETEC ditemukan pada 2 sampel (0,13%), masing-masing dari Puskesmas Batulicin dan Puskesmas Pagatan, sedangkan strain EPEC dan EAEC ditemukan pada 1 sampel (0,07%) yang sama dari Puskesmas Pagatan. Strain EHEC tidak terdeteksi di semua sampel. Strain Diarrhogenic E. coli yang ditemukan pada penelitian ini adalah EAEC, ETEC, dan EPEC. Namun demikian, belum dapat dipastikan bahwa ketiga strain DEC tersebut merupakan penyebab penyakit diare, perlu ada penelitian lebih lanjut. Masyarakat hendaknya dapat meningkatkan kesadaran akan pentingnya perilaku hidup bersih dan sehat terutama dalam mengkonsumsi makanan dan minuman, sehingga diharapkan mampu menekan angka kasus diare.

World Health Organization (WHO) menetapkan bahwa kriteria anemia menggunakan kadar hemoglobin, di mana pada wanita di bawah 12 g/dL dan pada pria kurang dari 13 g/dL. Tingkat anemia seseorang dipengaruhi oleh makanan yang dikonsumsinya, di mana seseorang mengkonsumsi makanan yang memiliki kandungan Fe rendah akan terjadi anemia. Haemoglobin merupakan bagian dari darah yang mempunyai peranan penting untuk membentuk sel darah merah. Zat besi dibutuhkan dalam proses pembentukan darah. Zat tembaga yang terkandung pada sari kurma dibutuhkan tubuh untuk membentuk sel darah merah. Produksi sel darah merah yang sedikit, rusaknya sel-sel darah merah dan kehilangan darah dapat menyebabkan seseorang menderita anemia. Sari kurma dan buah naga kaya akan zat besi yang bermanfaat untuk membentuk sel darah merah. Tujuan penelitian ini adalah untuk mengetahui pengaruh sari kurma dan buah naga dalam meningkatkan kadar haemoglobin. Populasi dalam penelitian ini sama dengan sampelnya, yaitu 40 pekerja wanita di konveksi Gelora Surakarta, yang dibagi menjadi dua kelompok yaitu 20 orang (kelompok  1) yang diberi sari kurma dan 20 orang (kelompok 2) yang diberi buah naga. Alat yang digunakan dalam penelitian ini adalah alat pengukur kadar haemoglobin dalam darah, chek list. Kesimpulan dari penelitian ini adalah Rata-rata kadar hemoglobin pre test dengan pemberian sari kurma sebesar 10,61 dan rata-rata kadar hemoglobin post test sebesar 11,53 dan rata-rata kadar hemoglobin sebelum dan sesudah diberi buah naga sebesar 10,42 dan rata-rata kadar hemoglobin post test sebesar 10,62.
