Abstract

As time goes by, more and more new factories appear producing different products. The manufacturing industry is related to tools that support the creation of a corn and grain processing process. PT. Seger Agro Nusantara is a company processing agricultural products such as rice and corn. One of the tools used at PT. Seger Agro Nusantara (SAN) is a forklift to help reduce worker energy in lifting and moving goods. The problem that often occurs with forklifts is the hydraulics. Hydraulics are the main part of a forklift which functions to move, lift and move goods from one place to another. The advantages and disadvantages of hydraulics are that they can transfer large amounts of power using only relatively small components, operate smoothly, do not cause noise or unimportant vibrations in the machine, can be rotated in the reverse direction (reversible), make it easy to move heavy materials in one lift. , or moving goods up to tons in weight. And the service life is quite long, so you can save on the cost of buying new equipment. Meanwhile, the disadvantage is that it requires intensive and regular maintenance. One method that can be used to find the root cause of a problem is a fishbone diagram. Because the fishbone diagram already knows the problem but doesn't know the cause.

Abstract

The best service includes providing fast service so that customers can arrive quickly. The service here can be in the form of improving the queuing system. Queues can occur if the need for a service exceeds the available demand. One service sector with a queuing system is the Community Health Center. The Community Health Center is a functional implementing unit that is a health development center for fostering community participation in the health sector. So, research was carried out to evaluate the queuing system at the Unter Iwes Health Center registration counter in Sumbawa District to optimize queuing services. The study results show that the queuing system currently used at the registration counter at the Unter Iwes Health Center, Sumbawa sub-district, namely Single Channel-Single Phase, is still optimal, as indicated by a steady state value of less than one. On Monday, it was found that the average queue in the system (????s) was one person, the average queue in the queue (????q) was one person, while the probability that the number of patients in the queue would not occur (????o) was 0%. The average waiting time in the system (????s) is 0.24 minutes, while the average waiting time in the queue (????q) is 0.15 minutes, the server busy level (K) is 64%, and the server unemployment level (W) is 36%.

Abstract

Preeclampsia is a serious pregnancy complication characterized by high blood pressure, potentially leading to organ damage, making early risk prediction crucial to reducing maternal morbidity and mortality. This study aims to develop a preeclampsia risk prediction model using medical and clinical data from 80 patients at Rumah Bersalin Sadan. The data include demographic profiles, blood pressure, weight, maternal age, preeclampsia history, body mass index, number of previous pregnancies, as well as genetic and environmental factors. The dependent variable is the risk of preeclampsia, either as a binary outcome (yes/no) or as a continuous risk score. The predictive model was built using multivariate linear regression and the Random Forest algorithm. The results showed that the Random Forest model achieved an accuracy of 65.22%, with an F-statistic of 7.345 and a very small p-value (1.908e-06), indicating that the model effectively explains data variability. However, the low Kappa value suggests room for improvement through feature refinement, hyperparameter tuning, or exploring other algorithms. Although these findings suggest that Random Forest is a promising method, further evaluation and model optimization are needed to enhance predictive performance and determine whether this method is the most suitable for the dataset used.
