Judul: Determinan Stunting pada Anak Usia 24-59 Bulan di Kelurahan Cimahpar, Kecamatan Bogor Utara
Abstrak: Tujuan penelitian adalah mengetahui determinan kejadian stunting pada anak usia 24-59 bulan di Kelurahan Cimahpar, Kecamatan Bogor Utara. Rancangan penelitian adalah cross sectional study dengan contoh 90 anak. Metode penarikan contoh yang digunakan adalah purposive sampling. Penelitian dilaksanakan pada bulan April-Mei 2016. Variabel yang diteliti pada penelitian ini adalah jenis kelamin, usia, berat badan lahir, besar keluarga, pendidikan ibu dan ayah, pendapatan perkapita, pengetahuan ibu, tinggi badan ibu, pola asuh makan, praktik kebersihan diri, pemanfaatan pelayanan kesehatan, sarana sanitasi, kondisi rumah, frekuensi dan lama sakit ISPA, frekuensi dan lama sakit diare. Hasil analisis regresi logistik menujukkan bahwa tinggi badan ibu <150.1 cm berisiko lebih tinggi memiliki anak stunting (OR=17.227; 95% CI 4.055-73.186); anak yang memiliki frekuensi ISPA yang rendah berisiko menjadi stunting lebih rendah (OR=0.099; 95% CI 0.025-0.386); anak yang memiliki lama ISPA yang rendah berisiko menjadi stunting lebih rendah (OR=0.202; 95% CI=0.055-0.744); semakin tinggi pendapatan perkapita risiko anak menjadi stunting semakin rendah (OR=0.056; 95% Cl=0.005-0.636); ibu yang memanfaatkan pelayanan kesehatan berisiko lebih rendah memiliki anak stunting (OR=0.956; 95% CI 0.921-0.993). Hasil analisis regresi logistik menunjukkan bahwa secara bersama-sama kelima variabel tersebut berpengaruh terhadap kejadian stunting (P=0.000;R2=0.610).

Judul: Pengetahuan, Sikap, dan Praktik Ibu Balita Stunting Usia 24−59 Bulan di Kecamatan Cibungbulang, Kabupaten Bogor
Abstrak: Stunting merupakan salah satu permasalahan gizi kronis di Indonesia yaitu kondisi kurangnya panjang atau tinggi badan balita menurut usianya yang berkaitan dengan pengetahuan, sikap, dan praktik ibu mengenai stunting. Penelitian ini bertujuan untuk mengetahui pengetahuan, sikap, dan praktik ibu mengenai stunting pada balita usia 24−59 bulan. Desain penelitian ini adalah cross sectional study yang dilaksanakan pada bulan November hingga Desember 2019 di Kecamatan Cibungbulang, Kabupaten Bogor. Subjek berjumlah 86 orang ibu yang memiliki balita stunting yang dipilih dengan metode purposive sampling. Hasil penelitian menunjukkan bahwa subjek memiliki pengetahuan dan sikap positif yang kurang mengenai stunting, yaitu 53,5% dan 66,3%. Namun, sebagian besar subjek memiliki praktik yang baik mengenai stunting (91,9%). Terdapat hubungan yang signifikan antara tingkat pendidikan ibu dengan pengetahuan ibu mengenai stunting (p=0,014). Hubungan antara pengetahuan dan sikap ibu mengenai stunting juga menunjukkan hasil yang signifikan berdasarkan uji korelasi Spaerman (p=0,000; r=0,617)., Stunting is one of chronic nutritional problems in Indonesia that is condition of the lack of length or height of toddlers according to their age related to the knowledge, attitude, and practice of mothers regarding stunting. The aim of this study is to determine the knowledge, attitude, and practice of mothers regarding stunting in toddlers aged 24−59 months. This study used a cross sectional study design which was conducted in November until December 2019 in Cibungbulang District, Bogor Regency. The subjects were 86 mothers with stunting toddlers who was selected by purposive sampling method. The results showed that the subjects had poor knowledge and positive attitude regarding stunting, i.e 53.5% and 66.3% respectively. However, most of the subjects had good practice regarding stunting (91.9%). There is a significant relationship between maternal education level and knowledge regarding stunting (p=0.014). The relationship between maternal knowledge and attitude regarding stunting also showed significant results based on the Spearman correlation test (p=0.000; r=0.617).

Judul: Synthesis of Apatite - Chitosan Composite Using Duck Eggshell and Chitosan with Temperature and pH Control
Abstrak: Composite of apatite-chitosan was prepared by using chitosan as polymer matrix. Calcium phosphate was prepared from CaO and (NH4)2HPO4, which the ratio Ca : P had to be 1.67. Chitosan is produced by deacetilase from biopolymer chitin. Duck eggshell (95% CaCO3) as starting material was converted to be calcium oxide (CaO) through calcinations with temperature 1000oC for 5 hours. In-situ and ex-situ methods were prepared from apatite and chitosan (dissolved with acetate acid 2%). Calcium phosphate prepared for bone implantation, but it is too fragile and brittle to be implant into the body. So addition of chitosan can decrease crystalinity and increase mechanic characteristic (tougher). Composite apatite-chitosan was resulted by fast precipitation. Fast precipitation was held in a breaker glass with nitrogen atmosphere, under controlled temperature at 37oC and pH 7, in order to increase amount of hydroxyapatite. Precipitation with CaO which was dropped by (NH4)2HPO4. Hydroxyapatite and chitosan were appearing at samples with in-situ and ex-situ methods which indicating by peak matching of XRD (closed lattice parameter, crystal size), overlapping at FTIR spectra and supporting by SEM picture (homogenous and agglomerated particle). However, it still needs further research to examine biocompatibility osteoconductive degree of sample by in-vivo and in-vitro test.
