Abstract: The purpose of this research to determine differences in understanding two-dimensional geometry concepts of students before and after application of worksheet in second grade students of SDN 7 Kebebu. This research is an pre-experimental research and used one group pretest-posttest design. Data collection techniques used essay tests. The Worksheet and instrument is validated by two experts namelly material expert and linguists used content validity. To determine reliability instrument data was analyzed used Cronbach Alpha formula, liliefors test for normality of data and t test to determine differences in understanding two-dimensional geometry concepts before and after used worksheet. The result of calculation used the t test showed that the sig value of 0,000 0,05 so that Ha is received. It can be conclude that there are significant difference in understanding two-dimensional geometry concept between before and after application of worksheet in second grade students of Elementary School 7 Kebebu.Keywords: worksheet, understanding two-dimensional geometry concept Abstrak: Penelitian ini bertujuan untuk mengetahui perbedaan pemahaman konsep bangun datar siswa sebelum dan sesudah penerapan Lembar Kerja Siswa (LKS). Penelitian ini merupakan penelitian pre-eksperimen dan menggunakan desain one group pretest-posttest. Teknik pengumpulan data menggunakan tes tertulis esai. Lembar kerja siswa (LKS) dan instrumen penelitian divalidasi oleh dua ahli yaitu ahli materi dan ahli bahasa menggunakan validitas isi. Untuk mengetahui reliabilitas instrumen data dianalisis dengan menggunakan rumus Alpha Cronbach, uji liliefors untuk kenormalan suatu data dan uji-t untuk mengetahui perbedaan pemahaman konsep bangun datar sebelum dan sesudah menggunakan lembar kerja siswa (LKS). Hasil perhitungan menggunakan uji-t menunjukkan bahwa nilai sig 0,000 0,05 sehingga Ha diterima. Maka dapat disimpulkan bahwa terdapat perbedaan pemahaman konsep bangun datar yang signifikan antara sebelum dan sesudah penerapan lembar kerja siswa (LKS) di kelas II Sekolah Dasar Negeri 7 Kebebu.Kata Kunci: Lembar kerja siswa (LKS), pemahaman konsep bangun datar

Gajah sumatera merupakan satwa endemik Indonesia yang tercatat ke dalam status yang terancam punah atau kritis. Dalam mempertahankan keberadaan dan kelestariannya maka populasi gajah harus dijaga. Gajah sumatera rentan terhadap berbagai penyakit, salah satunya disebabkan oleh parasit gastrointestinal. Infeksi parasit gastrointestinal merupakan faktor yang mengganggu kesehatan gajah sumatera. Penelitian ini bertujuan melihat keefektifan antelmintik dengan melihat keberadaan jenis endoparasit sebelum dan sesudah pemberian antelmintik pada gajah sumatera di tujuh lokasi Conservation Respon Unit (CRU) dan PKG Saree Aceh. Penelitian ini dilakukan pada Laboratorium Parasitologi FKH USK dan pengambilan sampel feses gajah pada CRU Sampoiniet Kabupaten Aceh Jaya, CRU Alue Kuyuen, Kabupaten Aceh Barat, CRU Trumon, Kabupaten Aceh Selatan, CRU Mila, Kabupaten Pidie Jaya, CRU Serbajadi, Kabupaten Aceh Timur, CRU Das Peusangan, Bener Meriah, dan PKG Saree Aceh. Data yang diperoleh dianalisis dengan Fecal Egg Count Reduction Test (FECRT). Hasil FECRT menunjukkan efektivitas antelmintik yang digunakan dalam mengobati gajah sumatera pada CRU Aceh sangat efektif hingga mencapai 100% terhadap parasit yang menyerang gajah sumatera di CRU dan PKG Aceh. Kata kunci: gajah sumatera, parasit pada gajah, antelmintik Sumatran elephants are endemic to Indonesia which are listed as endangered or critical. In maintaining its existence and sustainability, the elephant population must be maintained. Sumatran elephants are susceptible to various diseases, one of which is caused by gastrointestinal parasites. Gastrointestinal parasitic infection is a factor that interferes with the health of the Sumatran elephant. This study aims to examine the effectiveness of anthelmintics by observing the presence of endoparasites before and before offering anthelmintics to Sumatran elephants at seven locations of the Conservation Response Unit (CRU) and PKG Saree Aceh. This research was conducted at the USK FKH Parasitology Laboratory and took samples of elephant feces at the Sampoiniet CRU, Aceh Jaya Regency, Alue Kuyuen CRU, West Aceh Regency, Trumon CRU, South Aceh Regency, Mila CRU, Pidie Jaya Regency, Serbajadi CRU, East Aceh Regency, CRU Das Peusangan, Bener Meriah, and PKG Saree Aceh. The data obtained were analyzed by Fecal Egg Count Reduction Test (FECRT). FECRT results show the effectiveness of deworming drugs used in treating Sumatran elephants at CRU Aceh is very effective up to 100% against parasites that attack Sumatran elephants at CRU and PKG Aceh. Key words: Sumatran elephant, parasites in elephant, anthelmintic

ABSTRAKSalmonella sp. merupakan bakteri patogen yang dapat menyebabkan penyakit salmonellosis dan berperan penting dalam kasus foodborne disease. Penelitian ini bertujuan untuk mendeteksi keberadaan Salmonella sp. pada jajanan siomay yang dijual di Kota Banda Aceh. Sebanyak 16 sampel (masing masing delapan sampel siomay dan saus kacang) diambil secara acak dari delapan pedagang siomay di kota Banda Aceh. Isolasi bakteri dilakukan dengan menggunakan media pengayaan yang diinkubasi selama 24 jam, pada suhu 37˚C. Identifikasi dilakukan melalui pengamatan morfologi koloni, identifikasi secara mikroskopis, dan uji biokimia. Hasil penelitian menunjukkan bahwa tujuh sampel (43,75%) dari total 16 sampel yang diuji telah terkontaminasi Salmonella sp. Kontaminasi ditemukan sekitar 25% berasal dari siomay, dan 18,75% dari saus kacang.

Makanan yang kerap dijual di pinggir jalan yaitu bakso bakar. Bakso bakar adalah makanan yang proses memasaknya dengan cara dibakar di atas arang. Penelitian ini bertujuan untuk mendeteksi cemaran bakteri patogen yaitu Salmonella sp. yang terdapat pada bakso bakar. Metode penelitian menggunakan metode survey dengan pendekatan cross sectional. Pengambilan sampel dilakukan dengan teknik sampling sensus. Bakso bakar dihancurkan dengan stomacher lalu dibiakkan di media Buffered Pepton Agar (BPW) lalu dilakukan penanaman pada media selektif Salmonella Shigella Agar (SSA). Hasil penelitian menunjukkan bahwa dari 10 sampel yang diperiksa ditemukan empat sampel positif tercemar Salmonella sp. dan enam sampel negatif tidak tercemar Salmonella sp.. Kesimpulan, bahwa bakso bakar yang dijual di Kopelma Darussalam Banda Aceh tercemar Salmonella sp. Kata kunci: Bakso bakar, Banda Aceh, Salmonella sp..
