Abstract

Palm trees are now getting scarce, as many are old and cut down. The absence of technology that can shorten the dormancy of sugar palm is an obstacle that is still faced in the provision of palm seeds. The cause of dormant seed dormancy is the thick skin of the seeds and the unbalanced stimulants and inhibitors present in spurring germination activity. Eliminating the dormancy period is one way for the provision of seeds briefly. This study used RAK method with one factor experiment. From the experiment there were 5 treatments with 5 replications. The treatment is a1: Without treatment (control), a2: Approximate to the bud eye, a3: Given a hole near the bud eye, a4: Beaten with a hammer on the seeds of palm sugar and a5: Soaked in water with an initial temperature of 75o C for 15 minutes. The results showed that the physical treatment to break the dormancy aren gives effect, on percentage parameter germination, sprout sprout 50% growth rate and length radikula. The hole treated treatment was the best treatment in declaring dormancy of palm seeds with the highest percentage of germination percentage of 66% and the fastest 50% sprout time growth rate of 0.64 (4.4 days)

Abstract

ABSTRACTBackground: Stunting was a chronic nutrition problem that still be a concern in the developing nations include Indonesia. The direct cause of stunting was infectious disease and inadequate food intake such as energy and protein deficiency. In Indonesia in 2010, the prevalence of stunting was 35.7%, inYogyakarta as much as 22.5%, in Bantul District in 2012 was 18.08% and in Sedayu Subdistrict was 30.51%.Objectives: To know the history of energy and protein intake as the risk factors of stunting in children of 6-23 months.Methods: This was an observational study with case-control design. The population were children aged 6-23 months who lived in Sedayu Subdistrict, Bantul. The measurement energy and protein intake used a semi-quantitative food frequency questionnaire and determination of stunting used the WHO standard anthro 2005. Samples were selected by total sampling approachment. Data was analyzed by chi-square and logistic regression test.Results: The result of bivariate analysis showed that birth weight and maternal height had significant association with stunting (p<0.05). While energy and protein intake did not associated with stunting. However, there was a tendency that children with less energy and protein intake had higher risk of stunting. Multivariate analysis showed that maternal height was the dominant variable effect on the prevalence of stunting (OR=2.06).Conclusions: Low energy and protein intakes were not risk factors of stunting in children 6-23 months. Maternal height was dominant variable that influenced the stunting incidence.KEYWORDS: energy intake, protein intake, stunting, childABSTRAKLatar belakang: Stunting merupakan masalah gizi kronis yang masih menjadi perhatian di negara berkembang termasuk Indonesia. Penyebab langsung stunting adalah penyakit infeksi dan asupan makanan yang tidak memadai seperti kurang energi dan protein. Di Indonesia pada tahun 2010 prevalensi stunting sebanyak 35,7%, di Daerah Istimewa Yogyakarta sebanyak 22,5%, di Kabupaten Bantul tahun 2012 sebesar 18,08% dan Kecamatan Sedayu 30,51%.Tujuan: Untuk mengetahui riwayat asupan energi dan protein sebagai faktor risiko stunting pada anak usia 6-23 bulan.Metode: Jenis penelitian observasional dengan rancangan case-control. Populasinya seluruh anak usia 6-23 bulan yang ada di wilayah Kecamatan Sedayu Kabupaten Bantul. Pengukuran asupan energi dan protein dengan menggunakan semi-quantitative food frequency questionnaire dan penentuan stunting dengan menggunakan baku standar WHO anthro 2005. Cara pengambilan sampel adalah dengan total sampling. Analisis data menggunakan uji chi-square dan regresi logistik. Hasil: Berat bayi lahir dan tinggi badan ibu menunjukkan hubungan signifikan dengan kejadian stunting (p<0,05), sedangkan riwayat asupan energi dan protein tidak berhubungan dengan stunting (p>0,05). Secara multivariat, tinggi badan ibu merupakan variabel yang dominan berpengaruh terhadap stunting(OR=2,06).Kesimpulan: Asupan energi dan protein yang kurang bukan merupakan faktor risiko kejadian stunting pada anak usia 6-23 bulan. Tinggi badan ibu merupakan variabel yang dominan berpengaruh terhadap kejadian stunting.KATA KUNCI: asupan energi, asupan protein, stunting, anak
