PENGARUH PAPARAN MEDAN MAGNET EXTREMELY LOW FREQUENCY (ELF) TERHADAP DERAJAT KEASAMAN (pH) BUAH TOMAT

ABSTRAKExtremely Low Frequency (ELF) adalah spektrum gelombang elektromagnetik frekuensi 0-300Hz . Penelitian radiasi dari medan magnet ELF berdampak positif bagi bahan pangan karena bersifat non-ionizing. Tomat merupakan buah dengan kandungan gizi yang tinggi, namun memiliki masa simpan pendek yaitu ± 7-8 hari pada suhu diatas C. Alternatif cara memperpanjang umur tomat paparan maget ELF. Tujuan penelitian ini untuk menganailis ada atau tidaknya pengaruh pH tomat. Sampel digunakan berjenis Apel (Lycopersicum Pyriporme). Jenis eksperimen laboratorium dan desain Rancang Acak Lengkap. berjumlah 180 terbagi atas kelompok kontrol (30 sampel) eksperiman (150 perlakuan intensitas 600 µT 1000 selama 30, 60 90 menit. dikerjakan 20 hari. Pengolahan data analisis dilakukan uji kruskal wallis melalui software IBM Statistic SPSS 23. Kesimpulan hasil didapatkan bahwa adanya terhadap sampel ditandai perubahan nilai akibat aktivitas mikroorganisme patogen dalam terganggu. Hal tersebut dibuktikan grafik setiap pengukuran sangat tajam perubahannya dibandingkan cenderung berubah selisih sedikit. Kata kunci: radiasi; extremely low frequency; apel (lycopersicum pyriporme) ABSTRACTExtremely is a spectrum of electromagnetic waves with frequency 0-300Hz. Research Radiation from the magnetic field has positive impact on foodstuffs because it Tomato fruit high nutritional content, but short shelf life days at temperatures above An alternative way to extend tomatoes by exposure radiation. The purpose this study was analyze presence or absence effect tomatoes. sample used apple tomato type research laboratory experiment and completely randomized design research. A total samples were divided into control group samples) an experimental treatment intensity T for minutes. carried out days. Data processing analysis using Kruskal Wallis test Statistical 23 software. conclusion results obtained that marked changes in values due disturbed activity pathogenic microorganisms This evidenced graph each measurement group, are very sharp compared which tends change slight difference.
