Background: The welding workshop in Semarang City is spread over several areas in Semarang City. There are several types of work in welding workshops, namely, cutting raw materials, assembling, welding, grinding, sanding, and painting. This study aimed to analyze occupational safety and health risks in the informal welding workshop using the JSA (Job Safety Analysis) AS/NZS 4360:2004 Risk Management method. Method: This research was conducted using semi-quantitative method with descriptive analysis. A cross-sectional research design was used because data (observations, interviews, filling in risk analysis tables, work accidents, occupational diseases, and controls) were collected at a particular time. The study was conducted in Semarang, Central Java, and the population was all informal welding workshops. Result: This study showed that there are 8 types of welding tasks, 21 potential hazards, and 24 health consequences in a welding process. The total score calculated by multiplying "chance" by "severity" shows that 11 health consequences were acceptable risk while 13 others were high risk. Conclusion: The highest score of occupational health hazards was electric shock due to chipped cable, electric shock due to a chipped short circuit, and wet/rain/cloudy work area. Welders are recommended to follow the proper instruction in the welding process, and each workshop must provide a first aid box for its workers.

Posyandu is an integrated health service post where the post is a Community-Based Health Effort (UKBM) held for the community. As a means for the community to obtain basic health services, especially for mothers and children. In its service posyandu there are still deficiencies in services such as registration of services and counseling is still done conventionally, and recording of health services to mothers and children in the process is still using the method of service recorded in a Health Towards Card (KMS). To resolve the above problems required an artificial intelligence-based information technology (artificial intelligence) by using a database or database knowledge (knowledge base). In order for the Posyandu Electronics to run well, human resource readiness is needed to manage. By because it needs a model of information technology through the Electronic IHC as a solution in resolving problems of maternal and child health services. Model utilization of electronic information technology posyandu this will be known association with the use of information technology karekteristi factor K , attitude, performance, and training conducted for health workers and cadres Posyandu. Penelitian a research descriptive dngan capture qualitative data through questionnaires were processed by using structural equation modeling through Amos, Liserel and SPSS. The final result of this study is the creation of a model for the use of information technology through Electronic Posyandu as a means of conducting maternal and child health services to prevent , inhibit and reduce the ratio of maternal and child mortality in Indonesia.
