Penelitian ini bertujuan untuk mengetahui pengaruh yang terbaik serta mengetahui nilai organoleptik daging sapi bali hasil marinasi menggunakan madu trigona. Marinasi daging dilakukan selama 30 menit pada suhu ruang. Rancangan penelitian yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan empat perlakuan dan tujuh ulangan. Keempat perlakuan tersebut adalah daging yang tidak dimarinasi (P0); daging yang dimarinasi menggunakan madu trigona 5 ml (P1); daging yang dimarinasi menggunakan madu trigona 10 ml (P2); dan daging yang dimarinasi menggunakan madu trigona 15 ml (P3). Variabel yang diamati pada penelitian meliputi warna, aroma, rasa, tekstur, keempukan, dan penerimaan keseluruhan yang dinilai oleh 15 orang panelis semi-terlatih. Hasil penelitian menunjukkan bahwa daging sapi bali yang dimarinasi menggunakan madu trigona memberikan pengaruh nyata terhadap warna, aroma, rasa, keempukan dan penerimaan keseluruhan, namun tidak memberikan pengaruh yang nyata terhadap tekstur. Simpulan dari penelitian ini adalah marinasi daging sapi bali yang paling baik adalah menggunakan madu trigona dengan level 10 ml terlihat dari peningkatan nilai aroma, rasa, tekstur, keempukan, dan penerimaan keseluruhan panelis.

The cognitive aspect of arithmetic ability is a necessary aspect for students that deserves attention. This is because arithmetic cognitive ability is a tool that children will use in facing life. In addition, arithmetic cognitive ability is a basic ability for a child to solve everyday problems and is a tool for further education. Snakes and ladders can be adopted as a learning aid for kindergarten children to improve their counting ability. Teachers can consider using snakes and ladders as a teaching method, as it is considered effective for kindergartners who still have a play instinct. The purpose of this research is to understand the effectiveness of the snakes and ladders learning tool in improving children's counting ability. This research was conducted using qualitative and descriptive methodologies. The population and sample were taken from Group B of Aisyiyah Bustanul Athfal Bumi Mulyo Kindergarten with a total of 16 students. Data collection was done through several ways such as observation, interview, and documentation. The data obtained was then analyzed using several steps, namely; data reduction, data presentation, and conclusion drawing. The results showed that the use of the snakes and ladders tool can help improve arithmetic ability in Group B students of Aisyiyah Bustanul Athfal Bumi Mulyo Kindergarten in the 2021/2022 academic year

Background: Neck pain is pain that includes disorders of the nerves, tendons, muscles and ligaments around the neck. One of the causes of neck pain is the wrong position of the body which causes the neck in a certain position for a long time. In the use of cell phones there will be a process of changing the position of the neck, the position of the head will be bow to look at the cell phone screen and maintained for a long time, causing muscle problems which, if left unchecked, can become chronic muscle pain. Objectives: To find out relationship between the bow position when using a cell phone and neck pain. Methods: This study is an analytic-observational study with a cross-sectional design. The sampling technique used simple random sampling technique. The data will be analyze using chi-square statistical test. In which the p-value < 0.05 is significant. Results: There is a relationship between the bow position when using a cell phone to neck pain with p-value 0.045. On the other test, there is no relationship between the duration of cell phone use and neck pain, both in one use (p = 0.509) and in a day (p = 0.729). Conclusion: There is a significant relationship between the bow position when using a cell phone and neck pain. Keywords: neck pain, cell phone, bowing position Latar Belakang: Nyeri tengkuk adalah rasa nyeri yang meliputi kelainan saraf, tendon, otot dan ligamen di sekitar leher. Salah satu penyebab dari nyeri tengkuk adalah posisi tubuh yang salah sehingga membuat leher berada dalam posisi tertentu dalam jangka waktu yang lama. Pada penggunaan telepon seluler akan terjadi proses perubahan posisi leher, yang mana posisi kepala akan menunduk untuk melihat ke arah layar telepon seluler dan dipertahankan dalam waktu yang relatif lama, sehingga menimbulkan masalah otot yang apabila dibiarkan dapat menjadi nyeri otot kronis. Tujuan: Untuk mengetahui hubungan posisi menunduk saat menggunakan telepon seluler dengan nyeri tengkuk. Metode: Penelitian ini merupakan penelitian analitik-observasional dengan desain cross-sectional. Pengambilan sampel dilakukan dengan teknik simple random sampling. Hasil pengukuran akan dianalisis menggunakan uji chi-square. Nilai p < 0,05 dianggap signifikan. Hasil: Terdapat hubungan antara posisi menunduk saat menggunakan telepon seluler terhadap nyeri tengkuk dengan nilai P = 0,045. Pada uji hubungan lainnya tidak ada hubungan antara durasi penggunaan telepon seluler terhadap nyeri tengkuk baik dalam sekali penggunaan (P = 0,509) maupun dalam sehari penggunaan (P = 0,729). Kesimpulan: Terdapat hubungan yang signifikan antara posisi menunduk saat menggunakan telepon seluler dengan nyeri tengkuk. Kata Kunci: nyeri tengkuk, telepon seluler, posisi menunduk

Oxidation reactions on foods and drugs can be inhibit by using antioxidants that binding to free radicals and reactive molecules. The Ambonese banana (Musa paradisiaca) peel and orange (Citrus reticulata) peel have antioxidant activity potency. The aim of this research is knowing the antioxidant activity of combination Ambonese banana (Musa paradisiaca) peel and orange (Citrus reticulata) peel. IC50 for antioxidant activity potency between Ambonese banana (Musa paradisiaca) peel and orange (Citrus reticulata) peel is expected to increase the antioxidant activity if used as combination that can inhibit oxidation reaction. The inhibit concentration of antioxidant activity is indicated by IC50. The compound that has the highest antioxidant activity will show lowest level of IC50. The antioxidant activity test was performed by DPPH method using UV-Vis spectrophotometer on 516 nm and color change of DPPH from purple to yellow when both of them react with antioxidant compound. The results of IC50 of banana peel extract was 114 mcg / mL; IC50 of orange peel extract was22.2 mcg / mL. The greatest inhibition of the combination of both extracts was 73.53% consisting of 25 μL (0,005%) sample of tangerine orange peel extract and 75 μL (0,015%).The biggest inhibition of the combination of both extracts was 73.53% consisting of 25 μL (0.005%) samples of tangerine orange peel extract and 75 μL (0.015%).
