Abstract

Angka kejadian gizi kurang di Indonesia tahun 2010 sebanyak 17,9%. Angka kejadian BGM (Bawah garis merah) pada bayi di kabupaten karawang tahun 2012 sebanyak 11,43 %.Kepala Puskesmas Cikampek menyatakan bahwa sebanyak 14 balita di kecamatan cikampek terindikasi menderita gizi buruk. Kurang gizi pada bayi dapat menghambat pertumbuhan dan perkembangannya. Sehingga tidaklah salah bila banyak kecemasan orang tua terfokus pada kenaikan berat badan bayi khususnya dalam tahun-tahun pertama kehidupannya.  Kenaikan berat badan bayi. sangat dipengaruhi oleh asupan nutrisi. Pijat bayi mudah dipelajari dan umumnya dengan beberapa kali latihan para orang tua sudah mahir, disamping murah karena hanya memerlukan minyak/baby oil, juga banyak manfaatnya. Salah satu dari manfaat pijat bayi adalah peningkatan nafsu makan ini ditambah dengan peningkatan aktivitas nervus vagus/saraf pengembara (system saraf otak yang bekerja untuk daerah leher ke bawah sampai dada dan rongga perut) dalam menggerakkan sel peristaltic (sel di saluran pencernaan yang menggerakkan dalam saluran pencernaan. Dengan demikian, bayi cepat lapar atau ingin makan karena pencernaannya semakin lancar.Air susu ibu (ASI) merupakan asupan nutrisi utama pada bayi khususnya bayi dibawah 6 bulan.  ASI diproduksi atas hasil kerja gabungan antara hormone Oksitoksin,  Prolaktin dan Reflek Let Down. Sehingga faktor psikologis ibu dan faktor bayi sangat berkaitan dengan produksi ASI.   Penelitian ini merupakan penelitian analitik dengan jenis penelitian yang digunakan yaitu Quasy experimenntal (eksperimen semu) berupaya mengungkapkan hubungan sebab akibat antara variabel bebas (prediktor) denagn variabel tergantung (efek) dalam periode waktu tertentu. Populasi dalam penelitian ini adalah semua bayi 1-3 bulan di Puskesmas Cikampek Karawang.Pengambilan sampel dengan teknik purposive sampling berdasarkan kriteria inklusi dan eklusi. Untuk menganalisis pengaruh pijat bayi terhadap frekuensi dan durasi menyusu pada bayi 1-3 bulan di Puskesmas Cikampek Kabupaten Karawang dengan menggunakan Uji T test. Hasil penelitian diperoleh data bahwa ada pengaruh antara pijat bayi dengan frekuensi menyusu pada bayi dengan nilai P (0,000) dan tidak ada pengaruh antara pijat bayi dengan durasi menyusu pada bayi ( P value 0,563 ). Diharapkan bidan dapat terus memotivasi ibu untuk melakukan pijat bayi sehingga akan meningkatkan frekuensi menyusui pada bayinya dan memotivasi untuk tetap memberikan ASI Eklusif pada Bayinya.

Abstract

Glucose is a simple monosaccharide containing an aldehyde group and six carbon atoms. Glucose is an intermediate product in biological and chemical conversion. Glucose can made from hydrolysis of biomass such as oil palm leaves. Previously, oil palm leaves are only used as fertilizer and animal feed. Biomass with the main component cellulose is very resistant to hydrolysis by water, therefor a catalyst in the form of acidic or alcalyc is needed. The purpose of this study was intended to examine the use of oil palm leaves as a raw material in the manufacture of glucose. There are two stages in this research, pretreatment and hydrolysis. The pretreatment using acid solvents with low concentrations of 0,5% H2SO4 with the cooking process at 80°C for 1 hour reaction time. The results showed that the acid pretreatment process using 0,5% H2SO4 solvent was able to increase cellulose 2%, hemicellulose 1%, and lignin reduction by 1%. The hydrolysis process is carried out in two stages, first stage is immersion of oil palm leaves with an H3PO4-H2SO4 catalyst ratio of 70:30 for 16 hours at room temperature. Then the second step is adding distilled water and cooked at a temperature variation of 100°C, 120°C and takes 2 hours, 3 hours and 4 hours. The highest glucose yield obtained from the hydrolysis process at 100°C for 4 hours at 26,8376% and the lowest glucose yield obtained from the hydrolysis process at 120°C for 4 hours at 18,1812%Keywords : Glucose, hydrolysis, oil palm leaves

Abstract

Hydroxyapatite (Ca10(PO4)6(OH)2) is the most stable form of calcium phosphate, which is widely used in various medical applications, mainly in orthopedics and dentistry due to it?s similarities with inorganic mineral component of bone and teeth. However, in spite of chemical similarities, mechanical performance of synthetic hydroxyapatite is very poor compared with that of natural bone. It is possible to improve the properties of hydroxyapatite ceramics by controlling important parameters of powder precursors such as particle size, particle shape and agglomeration. Generally, natural or synthesized hydroxyapatite particles have rod-like and spherical-like. Different shapes of hydroxyapatite will affect biological response to human body, and the adaptation of osteoblast with hydroxyapatite. In this work, the synthesis of hydroxyapatite with various shapes has been done succesfully with the aid of precipitation method, by controlling the temperature. Spherical-like hydroxyapatite was synthesized at 30oC, rod-like hydroxyapatite was synthesized at 50oC and 70oC, and needle-like hydroxyapatite was synthesized at 90oC. FTIR analysis showed that the apatite compound has been formed with the absorption of PO4 3- and OH - ion at the wave number 1027.64, 1026.96, and 3301.69 cm-1. XRD analysis showed the similarities with standard hydroxyapatite ICDD 01-074-0566. The degree of crystallinity will be higher as long as temperature increased.Keywords: hydroxyapatite, particle shape, duck eggshells, temperature, precipitation method

Abstract

Corrosion is a decline quality of a metal because of chemical reaction a metal with its environment. The use of inhibitors is one way of corrosion control on metals, especially on the inside of the pipe. Pineapple leaf extract can be used as a green inhibitor. This study aims to utilize pineapple leaf extract as a green inhibitor about concentration of the inhibitor in controlling the corrosion rate by varying the time of the metal immersion. Extraction is done with a ratio of ethanol: distilled water, which is 1: 4. Research variations were corrosive media (0.1 M H2SO4), inhibitor concentrations (0, 2 gr/L) and immersion time (16, 32 and 48 hours). The method used is the weight loss method. The lowest corrosion rate in 0.1M H2SO4 solution is a concentration of 2 gr/L and a 48 hour immersion time of 20,686 mpy. The highest inhibitor efficiency in 0.1M H2SO4 solution concentration of 2 gr/L and time immersion for 48 hours amounted to 85.48%. It can be concluded that more inhibitors on corrosive media are able to produce low corrosion rates with high inhibition efficiency.Keywords: corrosion rate, inhibition efficiency, inhibitor, pineapple leaf
