Pandan dodol produces an optimal production quantity of 110 pcs with a profit of Rp.10.920.000. and dodol durian produces an optimal production quantity of 125 pcs with a profit of Rp.9.990.000
Penerapan Penerapan Spatial Autoregressive Model (SAR) Untuk Mengetahui Faktor-Faktor yang Memengaruhi Indeks Pembangunan Manusia (IPM)
No full textIndeks Pembangunan Manusia (IPM) merupakan indeks pembangunan manusia yang dipergunakan untuk pencapaian hasil dari pembangunan suatu daerah atau wilayah dalam tiga dimensi dasar yaitu lamanya hidup, pengetahuan atau tingkat pendidikan dan standar hidup layak. Untuk penggunaan variabel-variabel dalam penelitian yang memengaruhi Indeks Pembangunan Manusia yaitu Rata-Rata Lama Sekolah dan Pengeluaran per Kapita disesuaikan di provinsi Lampung pada tahun 2022. Metode operasional yang ada sekarang ini sebagian besar belum menggunakan pendekatan spasial. Pendekatan spasial atau pendekatan keruangan adalah pendekatan yang mengkaji rangkaian persamaan dari perbedaan fenomena geosfer dalam ruang. Di dalam pendekatan keruangan ini perlu diperhatikan adalah persebaran penggunaan ruang dan penyediaan ruang yang akan dimanfaatkan. Belum banyaknya penggunaan pendekatan sepasial sebagai perangkat analisis obyek, sehingga belum dapat memberikan gambaran pola penyebaran. Untuk mengatasi masalah tersebut digunakan suatu metode pendekatan spasial yang memungkinkan pengukuran Indeks Pembangunan Manusia beserta variabel-variabel yang mempengaruhinya ditampilkan dalam bentuk visualisasi untuk memberikan informasi yang mudah dipahami di analisis khususnya dalam hal membandingkan. Berdasarkan hasil penelitian diperoleh bahwa Rata-Rata Lama Sekolah dan Pengeluaran per Kapita Disesuaikan dapat mempengaruhi secara langsung Indeks Pembangunan Manusia di Kabupaten/Kota Provinsi Lampung tahun 2022. Dalam hal ini Indeks Pembangunan Manusia tidak hanya dipengaruhi variabel-variabel bebas namun terdapat efek spasial didalamnya
Faktor-Faktor Yang Mempengaruhi Minat Siswa SMA Untuk Melanjutkan Pendidikan Ke Perguruan Tinggi dengan Latent Class Regression Analysis
No full textInterest is an internal component within an individual that greatly influences his actions. Education is the process of changing the attitudes and behavior of a person or group in an effort to mature a person through teaching or training. The aim of this research is to determine the factors that influence high school students\u27 interest in continuing their education to higher education using the latent class regression analysis method. The latent class regression analysis method can determine the influence of accompanying variables or covariates in the formation of latent classes. The most dominant factors influencing high school students\u27 interest in continuing their education to higher education are needs, facilities and attention. In the first class the influencing factor is need. In the second and third classes the influencing factor is facilities. In the fourth class the influencing factor is attention
Peramalan Jumlah Kasus Tuberkulosis di Rumah Sakit Umum Haji Medan dengan Metode Support Vector Regression-Particle Swarm Optimization
No full textTuberculosis is an infectious disease that is the leading cause of poor health and one of the major causes of death around the world, in 2021 north Sumatra ran sixth as the province with the highest Tuberculosis rate after Provinsi Jawa Barat, Jawa Tengah, Jawa timur, DKI Jakarta, and Banten. This may result from an unhealthy environment, an increase in nutrition events, the appearance of HIV/AIDS. Hence, this study aims to create a forecast model by the method of regression support (SVR) with an optimist Particle Swarm Optimazion (PSO). The initial stage of the study involves analyzing the data of those with tuberculosis that begins by calculating the correlation between data with the underlying factors. Then do the preprocessing to initial data value, selecting the number of features and normalization of data. After the analysis stage, regression calculations are made to compare the value of browsing and actual value using the Support Vector Regression (SVR) method of Support Vector Regression (SVR) with the Particle Swarm Optimization (PSO) so that a good fortune-giving result is obtained. The results of this study were obtained from an analysis with a value of MAPE = 35.85

Solusi Numerik Model SITA Menggunakan Metode Runge Kutta Fehlberg Untuk Memprediksi Penyebaran Penyakit HIV/AIDS Di Provinsi Maluku
No full textThis research aims to predict the spread of HIV/AIDS in Maluku Province using the Runge Kutta Fehlberg method. The mathematical model of the spread of HIV/AIDS disease is in the form of a system of differential equations that includes Susceptible (S) variable, namely individuals who are healthy but vulnerable to being infected with the HIV virus, Infected (I) variable namely individuals who are infected with the HIV virus, Treatment (T) variable namely individuals who receive antiretroviral therapy and AIDS (A) variable namely individuals who contract AIDS disease used as initial values. Values as parameter values are solved numerically using the Runge Kutta Fehlberg method performed as many as 10 iterations with an interval time of using data from Maluku Provincial Health Office and BPS-Statistics Indonesia from 2013 to 2022. Based on the data obtained, the average value of the data is used as the initial value where . The initial values and parameter values are substituted into the numerical solution and simulated using software Matlab as tools. The rate value of each class for the next 10 years is for the class rate of individuals susceptible to HIV infection (S) of 1.757.102 people, for the class rate of HIV-infected individuals (I) of 2482 people, for the class rate of individuals receiving antiretroviral treatment (ARV) (T) of 1516 people and for the class rate of individuals with AIDS (A) of 555 people. This means that the (S) and (T) populations will decrease over the next 10 years while the (I) and (A) populations will increase over the next 10 years
Efektivitas Pendekatan Kontekstual, Open-Ended, dan STEM dalam Pengembangan Kemampuan Berpikir Kritis Siswa: Systematic Literature Review
No full textEffective learning does not only aim to convey knowledge, but also to develop critical thinking skills that are important for students in facing various life challenges. Critical thinking skills enable students to analyze, evaluate and solve problems logically and independently. This article explores how contextual, open-ended and STEM learning approaches contribute to the development of students\u27 critical thinking skills. Using the Systematic Literature Review (SLR) method, this research collected and evaluated journal articles from the Google Scholar database published between 2019 and 2024, focusing on these three approaches. The results of the analysis show that the contextual approach helps students relate the learning material to real situations, which enhances their understanding and application of knowledge. The open-ended approach encourages students to find multiple solutions and improve their analytical skills, while the STEM approach emphasizes the integration of disciplines to facilitate collaborative and creative learning. These three approaches are proven to be effective in improving students\u27 critical thinking skills, which is reflected in their improved ability to identify, analyze and solve problems. This study provides important insights for educators and researchers to develop more effective learning strategies
