Abstract

World Health Organization (WHO) pada tahun 2020 mengatakan angka kematian ibu (AKI) didunia sebanyak 227.22 per 100.000 kelahiran hidup, penyebab kematian ibu hamil secara langsung salah satunya disebabkan oleh Preeklampsia. Preeklampsia adalah suatu penyakit yang dialami oleh ibu hamil yang ditandai dengan adanya tanda-tanda hipertensi (tekanan darah tinggi), eodema (pembengkakan), dan proteinuria (kadar protein dalam urin meningkat. Pada salah satu rumah sakit swasta di Cikarang kasus preeklamsia setiap tahunnya mengalami peningkatan, Rata-rata persentase peningkatan jumlah  pasien Preeklamsia dari tahun 2020 hingga 2022 sekitar 17,5% per tahun. Hal itu terjadi dikarenakan ibu hamil tidak menyadari ketika dirinya mengidap penyakit preeklamsia.Tanda-tanda awal preeklamsia hampir sama dengan penyakit hipertensi. Penelitian ini bertujuan untuk membuat model diagnosis penyakit preeklamsia. Harapannya model ini bisa sebagai Alat bantu self diagnoses, untuk deteksi awal penyakit preeklamsia agar bisa mencegah terjadinya penyakit Eklampsia yang dapat lebih membahayakan nyawa ibu dan janin. Dalam penelitian ini, beberapa skenario eksperimen diterapkan dengan mengubah jumlah tetangga terdekat (nilai K) untuk mengoptimalkan akurasi model nilai K yang berbeda beda, sehingga didapatkan hasil klasifikasi yang maksimal terdapat pada jumlah nilai K =3 dan K=5 dengan pemabagian data traing dan data testing 90:10 mendapatkan hasil akurasi 97%, sedangkan hasil klasifikasi terendah didapatkan pada pembagian data 50:50 untuk nilai K=9 sebesasr 84%.

Abstract

This research investigates the application of optimal control in the Susceptible, Exposed, Addicted, Recovery, Quit (SEA_1 A_2 RQ) model to address social media addiction. The primary objective is to develop an effective control strategy to reduce the prevalence of social media addiction. The methodology employs Pontryagin's maximum principle to formulate the optimal control problem, incorporating two time-dependent control variables: control (u_1) and treatment (u_2). The optimal control model is numerically simulated using the 4th-order Runge-Kutta method. Comparative analysis of the simulation results, with and without control, demonstrates significant differences in all population groups after four years. The findings reveal that implementing control (u_1) and treatment (u_2) markedly decreases the number of individuals addicted to social media, highlighting the efficacy of the proposed strategy in mitigating social media addiction.Keywords: Optimal control; Social media addiction model; Pontryagin maximum principle. AbstrakPenelitian ini mengkaji penerapan kontrol optimal pada model Susceptible, Exposed, Addicted, Recovery, model Quit (SEA_1 A_2 RQ)  untuk menangani kecanduan sosial media.

Abstract

Peatlands are suboptimal lands that can be improved its quality to be used for agricultural cultivation. One of which is by using red mud and biofertilizer. Red mud, a by-product of bauxite processing, is widely available in West Kalimantan. Red mud has high pH, electrical conductivity, exchangeable sodium and base saturation. Biofertilizers are products containing selected microorganisms that can help enhance plant growth and yield. This study aims to examine the effects of red mud and biofertilizer applications on peat quality improvement and their impact on the growth and yield of hybrid corn. The experiment was arranged in a randomized block design (RBD) with two factors. The first factor was red mud with three dosage levels: control (l0), 6 tons/ha (l1), and 12 tons/ha (l2). The second factor was biofertilizer with three types: control (p0), Mycofer at 10 g/plant (p0), and Provibio at 10 ml/l (p2). The results showed that red mud at a dose of 12 tons/ha significantly affected soil pH, electrical conductivity, plant growth, and hybrid corn yield. The interaction of 12 tons/ha red mud and Provibio biofertilizer significantly increased sodium content and achieved the highest uptake of phosphorus, potassium, calcium, and magnesium.

Abstract

The The A-Star algorithm is one of the most popular shortest route search algorithms due to its effectiveness in finding optimal solutions. This study focuses on modifying the A-Star algorithm to improve its performance in optimizing the shortest route. The study was conducted by comparing the standard A-Star algorithm and its modified version based on the number of iterations required to reach the optimal solution. The assessment was carried out manually and through a computer program using sample data from tourist locations in Blitar as a case study. The results of the analysis in 20 comparative experiments showed that the modified A-Star algorithm was able to minimize the number of iterations by up to 32% compared to the standard A-Star algorithm. This finding indicates that the modifications made to the A-Star algorithm can increase efficiency without reducing the accuracy of the results. This study provides an important contribution to the development of shortest route search algorithms, especially in their application to the tourism sector and navigation systems.

Abstract

Fuzzy Multi-Attribute Decision Making (FMADM) is a helpful method in decision support systems, as it is used to identify the best options among several options that meet the selected requirements. Fuzzy Weighted Product (FWP) is a method found in the FMADM method. The FWP method uses the concept of sorting by multiplying  the criterion rating, whose weight is the power of each of the criterion values. The purpose of this study is to apply the FWP method in determining KJP recipients. The stages in the FWP method started from the decision-making criteria of 191 students which included a lot of parental income, parental employment, vehicle ownership, and many dependents. Furthermore, the data is processed using the fuzzy system  and after that the application of the FWP method to perform further calculations. The stages are determining the weight and match rating, transforming the data, calculating the value of alternative preference (S), and the relative value of alternative (V). The best results are determined by the highest relative preference value. The results can be used for decision-making for KJP recipients at SDN Lubang Buaya 11 Pagi East Jakarta and help overcome underprivileged students in school fees.

Abstract

The community service program in Japanan Hamlet aims to optimize the processing of chili into chili oil products in order to increase the income of the Women Farmers Group (KWT). The local community, who are mostly farmers, often face challenges in utilizing the chili harvest optimally. In order to achieve this goal, this community service activity is carried out through several stages, namely problem identification, solution planning, and program implementation. The methods used in this community service are training and mentoring. The training program includes chili processing techniques, packaging that meets food safety standards, and digital marketing strategies to increase the selling value of the product. The implementation is carried out interactively and based on practice, starting with socialization about the benefits of chili oil and continuing with direct practice. The results of this program show that KWT mothers have increased their knowledge and skills regarding the chili processing process, from selecting raw materials to the packaging stage. In addition, this program also improves the skills of KWT mothers regarding the use of social media and marketplaces as a means of marketing. Despite challenges such as a lack of initial understanding of digital marketing, the solution steps that have been implemented have succeeded in having a positive impact on KWT, which not only gained new knowledge and skills, but also increased their income through value-added products. Through synergy between students, the community, and universities, this activity is expected to provide a significant contribution to the economic welfare of the local community
