Influence Oxytocin Massage on Reduce Lactation Problems and Support Infants Growth

Background: Lactation problems often occur in the early postnatal period. One of them is the readiness of the mother in early breastfeeding. Early breastfeeding is one of the effective efforts in providing nutrition for newborns and preventing lactation problems. In 2019, in Indonesia, the percentage of newborns who received early breastfeeding was 75.58%. The success rate of this is closely related to lactation readiness in early postpartum. To support the success of lactation, postpartum mothers need to be given education on methods to stimulate milk production at the beginning of the puerperium with oxytocin massage. Good breast milk production will support the nutritional adequacy of the baby and reduce lactation problems in the early postpartum period. Objectives: the purpose of this study was to determine the effectiveness of oxytocin massage on lactation problems and infant growth. Methods: This study was pre-experimental research using posttest only design and true-experiment using posttest only control group design. The research locations were in the Mother and Child Health Clinic and Midwives Independent Practice (PMB) in Bantul, Sleman, and Gunung Kidul Yogyakarta. Implementation from April until September 2020. The population of this study was all the families of postpartum mothers from the first to the third day and after 1 week an evaluation of breastfeeding. The sampling technique uses total sampling was 80 postpartum mothers on the first-third day of childbirth until the baby was 2 months old. The research instruments were the oxytocin massage checklist, lactation problems, and body length observation sheet. Test analysis using Wilcoxon. Results: The results of this study were that the majority of respondents performed oxytocin massage with a frequency more than 3 times (51%) the first week of postnatal, respondents experienced lactation problems in the first week of postnatal by 16.3% and at the 4th postnatal visit all respondents had no lactation problems. The average increase in the length of the baby's body at the age of 2 months is 8.44. The majority of the baby's body length at the age of 2 months corresponds to age (98.8%). The results of bivariate analysis of oxytocin massage were effective in reducing lactation problems (p=0.000) and supporting infants' growth (p=0.000). Conclusion: Oxytocin massage is effective in reducing lactation problems and supporting infants' growth. Oxytocin massage should be implemented in postnatal care to prevent lactation problems and support breastfeeding.

Isolation and identification of avirulent strains of Bacillus anthracis from environmental samples in Central Java, Indonesia

Background and Aim: Anthrax is a non-contagious infectious disease caused by Bacillus anthracis. The bacteria form spores that are resistant to extreme conditions and can contaminate the environment for decades. This study aimed to detect and characterize B. anthracis found in endemic areas of anthrax in Yogyakarta and Central Java province, Indonesia. Materials and Methods: Soil samples were collected from Gunungkidul regency, Yogyakarta province (n=315) and Boyolali regency, Central Java province (n=100). Additional soil samples (n=10) and straw samples (n=5) were obtained from Pati regency, Central Java province. The isolation and identification of B. anthracis were performed using conventional methods: Morphology of bacteria colony in solid media, Gram staining, capsule staining, spores staining, and motility test. Isolates were further identified using polymerase chain reaction (PCR) against Ba813, lef (pXO1), and capC (pXO2) gene. An avirulent vaccine strain of B. anthracis (strain 34F2) was used as a control. Results: Only four samples grew on blood agar with a ground-glass appearance, white-gray colony (Gunungkidul and avirulent strain) or yellowish (Boyolali and Pati). All were Gram-positive, presented chains, square-ended rods, spores, and were then identified as B. anthracis. Boyolali, Pati, and avirulent strain isolates had slightly different characteristics, including the growth of non-mucoid in the bicarbonate agar medium, and their uncapsulated form. The PCR showed two Gunungkidul isolates which amplified three genes, including Ba813, lef, and capC. Contrarily, the other isolates did not amplify the capC gene. Conclusion: Gunungkidul isolates were identified as virulent strains of B. anthracis while Boyolali and Pati isolates were proposed as avirulent strains. This is the first report of isolation and identification of avirulent strains of B. anthracis in Central Java, Indonesia.

The effect of oxytocin massage during postpartum on baby weight

<p><strong><em>Background:</em></strong><em>The low coverage of exclusive breastfeeding in Indonesia and the world can have a negative impact on mothers, babies, families, and even the country. Research by Rawat, et al (2018) states that one of the causes of failure of the breastfeeding process in primiparous and in the first week of delivery is that the mother finds it difficult to attach when breastfeeding and feels that breast milk is not enough. Another study conducted by Jacobs, et al (2013) also proved that the majority of respondents felt that breast milk production was scant, so they decided to provide formula milk. Meanwhile, research conducted by Madhavi and Manikyamba (2016) found that the reason for not giving exclusive breastfeeding was difficulty in the breastfeeding process. Therefore it is necessary to have a method to stimulate milk production at the beginning of postpartum, one of which is oxytocin massage. </em></p><p><strong><em>Objectives:</em></strong><em>The purpose of this study was to determine the relationship between the oxytocin massage and baby weight. </em></p><p><strong><em>Materials and methods:</em></strong><em>this study was a pre-experimental research using posttest only design and true-experiment using posttest only control group design.

Management of Gogo Rice Production in Realizing the Commercialization of Marginal Land Farming Households in Yogyakarta

The land is an important factor for people whose lives depend on the agricultural sector. The need for land for various uses has resulted in decreasing agricultural land which could have implications for decreasing food production. Alternative options which are expected to increase the potential for food production are the utilization of marginal land. Farmers with marginal land need to manage their production to meet household needs. So it is important to examine the marketable surplus, the level of commercialization, and the carrying capacity of marginal land. The research area was taken by purposive sampling method in Gunungkidul Yogyakarta. The samples taken were upland rice farmer households with the simple random sampling method. The marketable surplus analysis uses a marketable surplus formula, then the percentage is used to determine the level of farm commercialization. The carrying capacity analysis is carried out using the carrying capacity formula. The results showed that farmer households manage rice production by allocating an average of 59.1% for marketed and 40.9% for household consumption. The allocation of marketable surplus is greater than for household consumption, this shows that gogo rice farming households are towards commercially. The marginal land carrying capacity of 0.641 indicates that the land cannot be developed in an expansive and exploratory manner. The implication is in increasing upland rice production on marginal land, namely by an intensification of farming.

Uptake capacity of zeolitic tuff from Gunungkidul, Indonesia for environmental and agriculture application

Zeolitic tuff samples from Gunungkidul Yogyakarta, Indonesia was investigated for mineralogical and chemical composition and its uptake capacity. Five zeolitic tuff samples were obtained from the field and measured for the mineralogical, chemical composition, and uptake capacity by XRD analysis, ICP AES, and BaCl2 method, respectively. The result of mineralogical composition showed that the mordenite type-zeolite was found as significant zeolite mineral, with percentages varying from 24.1% to 38.1% and with an average amount of 34,3%. Chemical analysis revealed that the mordenite contents influenced amounts of SiO2 ranging between 60.06% to 66.06% and Al2O3 from 12.12% to 13.57%, and this Si/Al ratio obtained. The measured uptake capacity or cation exchange capacity (CEC) value varies from 67 meq/100 g to 98 meq/100 g with an average value of 82,4 meq/100 g. The vary of these values most probably was influenced by the differences in the percentage of zeolite minerals and other mineral impurities. Mordenite type of zeolite is thought the most affected of the uptake capacity, while clay minerals contribute to a relatively small influence. The uptake capacity of the five zeolitic tuff studied showed positive correlations with the content of mordenite-type zeolite as well as with the total content of microporous minerals and Si/Al ratio. These materials could be an excellent material candidate in a wide range and scale of agricultural, and environmental applications.
