Abstract

Exclusive breastfeeding is the giving of breast milk (ASI) in newborns to 6 months  babies without being given drinks or other food, breast milk can be given up to 2 years. Coverage of Exclusive ASI in Central Java Province 2017 (54.5%). In Grobogan Regency 2015 (67.67%), 2016 (10.18%), 2017 (11.1%), 2018 (10.38%). The research objective was to analyze the factors that influence exclusive breastfeeding in Grobogan Regency. The research was using cross sectional design. The research sample was 92 respondents that were obtained by cluster random sampling technique. Data collection techniques were interviews, observation, questionnaire. Data analysis in the study used the Chi Square test and logistic regression test. The results found no influence of family support variables (p = 0,000), prenatal guidance (p = 0,000), the role of midwives (0,000), culture (0,000), no effect of venostyle style (p = 0.493) on exclusive breastfeeding in Grobogan Regency. The most influential variables were prenatal guidance with p = 0,000; EXP (B) / OR = 0.040. Health centers in Grobogan Regency need to improve cadre orderliness, increase counseling for mothers and the community.

Abstract

Pneumatic tube system (PTS) is a sample transport medium that is widely used in hospitals. Samples sent using PTS may be shaken due to the varying speed and air pressure in the PTS. The use of PTS can affect the examination of platelet counts and potassium levels. The installation of PTS at the Gadjah Mada University Academic Hospital was carried out in May 2020 in the Yudistira, Arjuna, Kresna and Nakula buildings. Delivery of laboratory samples at RSA UGM every day can be done from buildings with different distances. Every hospital that uses PTS is advised to validate PTS and investigate blood specimens for the possibility of hemolysis and laboratory results. The purpose of this study was to validate the PTS distance as a transport medium for laboratory examinations. This research is an experimental research which is a follow-up study using 30 samples. Samples were taken twice and sent with the PTS from two different distances, namely YD 2 and IGD. The statistical test will use a paired sample t-test. The data will be analyzed with the help of Prima Graph 8 Statistical Software with a significance level of 5%. The results of the analysis showed that there was no difference in the results of the examination of platelets and potassium sent from YD 2 or from the ER.

Abstract

The objective of this research was to identify the most dominant waste, calculate the average cycle time per unit at each work station, and provide suggestions for improving the production process. The approach used was Lean Manufacturing with the tools of Value Stream Mapping (VSM) and Waste Assessment Model (WAM). VSM was used to map the process flow and identify non-value-added activities, while WAM was used to assess the dominance of waste using the Waste Relationship Matrix (WRM) and Waste Assessment Questionnaire (WAQ). The analysis results showed that defects were the most significant waste, contributing 14.57%. The main causes were inconsistencies in boiling temperatures and printing errors. In addition, imbalances in cycle times between work stations were found. Proposed improvements focused on the Future State VSM, in the form of process standardization, temperature control, and rearrangement of work areas. The implementation of this method is expected to improve production efficiency sustainably.
