PENGARUH PENDIDIKAN KESEHATAN ANTICIPATORY GUIDANCE TERHADAP KESIAPAN IBU MENGHADAPI FASE PUBERTAS PADA ANAK AUTIS USIA SEKOLAH (6-12 TAHUN) DI AUTIS CENTER BENGKULU

Autisme merupakan salah satu dari gangguan perkembangan pervasif. Anak autisme juga akan mengalami fase pubertas. Orang tua khususnya ibu memiliki peranan penting untuk mengarahkan anak autis agar dapat melewati fase pubertas dengan baik. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pendidikan kesehatan anticipatory guidance terhadap kesiapan ibu menghadapi fase pubertas pada anak autis usia sekolah (6-12 tahun) di Autis Center Bengkulu. Desain penelitian yang digunakan adalah pre experimental dengan rancangan one group pre test-post test tanpa kelompok kontrol. Sampel penelitian sebanyak 17 orang. Pengumpulan data menggunakan kuisioner dengan uji statistik McNemar (α = 0,05). Hasil penelitian menunjukkan bahwa terdapat perbedaan kesiapan ibu menghadapi fase pubertas pada anak autis setelah diberikan pendidikan kesehatan anticipatory guidance menggunakan metode ceramah dan demonstrasi (p value < 0,05). Kesimpulan dari penelitian ini adalah terdapat perbedaan kesiapan ibu menghadapi fase pubertas pada anak autis usia sekolah sebelum dan setelah diberikan pendidikan kesehatan anticipatory guidance (p value = 0,016). Disarankan pada penelitian selanjutnya dapat melakukan penelitian mengenai anticipatory guidance menghadapi fase pubertas pada anak autis dengan menggunakan metode, tempat, serta variabel lain yang berbeda.Kata Kunci : Pendidikan Kesehatan; Anticipatory Guidance; Pubertas; Autis; Kesiapan Ib

ANALISIS PENGARUH PAPARAN FISIK PADA SAMPEL GIGI TERHADAP HASIL KUANTIFIKASI DNA FORENSIK MENGGUNAKAN METODE KIT PURIFIKASI DNA KOMERSIAL

Physical exposure to biological samples has an enormous influence on the results of forensic DNA analysis. The lack of molecular research on the effect of physical exposure on dental samples is the reason for the need for further research. This study aims to determine the effect of physical exposure on dental samples on the results of forensic DNA quantification. The parameter used is the concentration value of isolated DNA obtained from real time PCR analysis. The use of real time PCR allows the detection and quantification of specific sequences of DNA samples at the same time to be analyzed. The dental samples used were obtained from different individuals. Teeth are used as identification media because teeth are the hardest part of the body and are chemically the most stable and most resistant to degradation and decomposition. The method in this study is to give three types of treatment to the tested samples in the form of sea water immersion, river water immersion and exposure to free air at room temperature with each treatment consisting of three test samples. All samples were extracted using a Commercial DNA purification KIT with a reagent in the form of a Qiagen KIT (QIAamp® DNA Investigator) then a quantification process was carried out to see the value of the DNA concentration of each sample using real time PCR. The results of DNA quantification of dental samples from each treatment showed that the highest sample concentration value was based on the average of each treatment, namely samples with treatments exposed to free air at room temperature with a concentration value of 1.34 ng/µl, followed by samples soaked using river water with a concentration value of 0.15 ng/µl, while the sample with the lowest concentration is shown by a sample treated with seawater immersion with a concentration value of 0.10 ng/µl. Physical exposure in the form of exposure to free air, exposure to river water and exposure to sea water on dental samples, gave a not too significant effect on the results of DNA quantification produced.Paparan fisik pada sampel biologis memberikan pengaruh yang sangat besar terhadap hasil analisis DNA forensik. Masih sedikitnya penelitian molekuler tentang pengaruh paparan fisik pada sampel gigi menjadi alasan perlu dilakukannya penelitian lebih lanjut. Penelitian ini bertujuan untuk mengetahui pengaruh paparan fisik pada sampel gigi terhadap hasil kuantifikasi DNA forensik. Parameter yang digunakan adalah nilai konsentrasi DNA hasil isolasi yang diperoleh dari analisis real time PCR. Penggunaan real time PCR memungkinkan dilakukannya deteksi dan kuantifikasi sekaligus terhadap sekuens spesifik dari sampel DNA yang dianalisa. Sampel gigi yang digunakan diperoleh dari individu yang berbeda. Gigi digunakan sebagai media identifikasi karena gigi merupakan bagian tubuh yang paling keras dan secara kimiawi merupakan jaringan paling stabil dan paling tahan terhadap degradasi dan dekomposisi. Metode dalam penelitian ini yaitu memberikan tiga jenis perlakuan pada sampel yang diuji berupa perlakuan perendaman air laut, perendaman air sungai dan paparan udara bebas pada suhu ruang dengan masing-masing perlakuan terdiri atas tiga sampel uji. Semua sampel diekstraksi menggunakan KIT purifikasi DNA Komersial dengan reagen berupa KIT Qiagen (QIAamp® DNA Investigator) selanjutnya dilakukan proses kuantifikasi untuk melihat nilai konsentrasi DNA dari masing-masing sampel menggunakan real time PCR. Hasil kuantifikasi DNA sampel gigi dari masing-masing perlakuan menunjukkan bahwa nilai konsentrasi sampel tertinggi berdasarkan rata-rata setiap perlakuan yaitu sampel dengan perlakuan terpapar dengan udara bebas pada suhu ruang dengan nilai konsentrasi sebesar 1,34 ng/µl, diikuti dengan sampel yang direndam menggunakan air sungai dengan nilai konsentrasi sebesar 0,15 ng/µl, sementara sampel dengan konsentrasi terendah ditunjukan oleh sampel yang diberi perlakuan perendaman air laut dengan nilai konsentrasi sebesar 0,10 ng/µl. Paparan fisik berupa paparan udara bebas, paparan air sungai dan paparan air laut pada sampel gigi, memberikan pengaruh yang tidak terlalu signifikan terhadap hasil kuantifikasi DNA yang dihasilkan

Tray Dryer's Performance in the Drying of Banana Slices Using LPG and Wood Stove

An evaluation was carried out on a simple tray dryer of banana slices in the "sale pisang" production. The dryer is designed to use gas fuel and a wood-burning stove as a source of energy. The dryer's performance is analyzed to evaluate its ability to dry the product efficiently and effectively to prevent excessive heat use. The research aims to analyze the temperature distribution in the drying chamber, the profile of the product's moisture content, the drying rate on each shelf, as well as the efficiency of dryers using gas fuel and wood-burning stoves. At an air speed of 0.0176 m3/s, the drying chamber reaches a maximum temperature of 76.2 ℃ using gas and 66.23 ℃ using a wood stove. The use of Liquid Petroleum Gas (LPG) gives an average room temperature of 73.46 ℃, while the furnace gives a less stable pattern with an average temperature of 63.02 ℃. Drying using LPG occurs more quickly with a constant drying rate and a falling rate period of 0.8262%/hour and 0.01504%/hour, higher than using wood fuel which is 0.5482%/hour and 0.0098 %/hour. Within 400 minutes, the product’s moisture content reached 24.64% using LPG and 36.762 using the furnace. The efficiency for heating the drying air is 28.51% and the drying process efficiency is 27% using 8.6 kilograms of LPG as fuel. Meanwhile, using a furnace energy source, the dryer provides a heating efficiency of 15.9% and a drying efficiency of 7.37% with a fuel consumption of 34.12 kg of wood.An evaluation was carried out on a simple tray dryer of banana slices in the "sale pisang" production.
