Permasalahan yang sering dihadapi oleh seseorang yang telah memasuki masa lanjut usia (lansia) bukan hanya perubahan secara fisik dan kognitifnya saja, namun juga berpengaruh besar terhadap keadaan psikososial dari lansia itu sendiri. Psikososial lansia yang tidak ditangani secara tepat akan mempengaruhi kualitas hidup baik kesehatan fisik maupun kemampuan kognitif lansia. Oleh karena itu, melalui program â€œTensi (Tenda Seni Lansia)â€ ini, diharapkan masyarakat lansia dapat melakukan suatu aktivitas yang bermanfaat dan menyenangkan sehingga kebutuhan psikososialnya dapat terpenuhi dengan baik. Untuk membuktikan keefektifan program, maka digunakan metode penelitian eksprimen dengan memberikan perlakuan pada lansia berupa aktivitas yang menghasilkan karya seni untuk melihat apakah terjadi peningkatan kreativitas dan interaksi antara masyarakat lansia dengan masyarakat diumur yang berbeda-beda. Jumlah sampel dalam penelitian ini sebanyak 8 lansia, penentuan sampel menggunakan teknik purposive sampling dengan kriteria lansia yang mengikuti kegiatan Tenda Seni Lansia. Teknik pengumpulan data dengan melakukan pre dan post test, wawancara dan observasi. Pengujian data pre dan post test menggunakan uji normalisasi dan uji paired t-test. Hasil yang diperoleh dari pengujian uji normalisasi data menunjukkan bahwa rata-rata nilai sampel pra dan pasca perlakuan memiliki perbedaan atau tidak sama. Hal ini berarti program TENSI efektif dalam meningkatkan kreativitas danÂ interaksi sosial antara masyarakat lansia melalui beberapa kegiatan yang terlaksana.Â Kata Kunci: Psikososial, purposive sampling, tenda seni lansia, uji normalisasi, uji paired t-test.

The involvement of teachers in Bone Regency in using information and communication technology (ICT) to prepare teaching materials is very little or even never said, even though computer facilities and infrastructure are available in the computing lab. This activity aims to provide knowledge to Mathematics teachers about online learning Google Classroom and Geogebra. The use of Google Classroom will make learning more effective for teachers and students because learning is no longer limited by space and time, student can explore learning resources easily and utilize information technology properly. Likewise, Geogebra training is expected to overcome the difficulties of teachers in visualizing concept charts in mathematics dynamically. The target audience for community service is mathematics teachers who are members of the Mathematics MGMP in Bone Regency.

Kalman Filter merupakan metode untuk memprediksi nilai suatu peubah di masa yang akan datang dengan mempertimbangkan data-data sebelumnya yang senantiasa di up-date. Metode ini selanjutnya akan diaplikasikan pada data survival penderita penyakit Tuberculosis (TB) dari penduduk Amerika Serikat. Metode ini sangat menarik untuk digunakan karena Tan (2004) hanya memanfaatkan metode state space saja dalam memprediksi nilai peubahnya. Oleh karena itu, pada paper ini akan memanfaatkan metode Kalman Filter dalam memprediksi nilai suatu peubah dari data survival penderita TB di Amerika Serikat.

Methods for Estimating Survival Time of Treatments for Renal Dialysis Sri Astuti Thamrin
Jurnal Matematika, Statistika dan Komputasi Vol. 14 No. 2 (2018): January 2018
Publisher : Department of Mathematics, Hasanuddin University

This papes discusses the theory and application of statistical methods for describing and analyzing survival times of the renal dialysis patients : a) from the first diagnosis until the time of death, and b) on each mode of given treatment. The paper also tries to predict the variables significantly effecting the survival time of renal dialysis patients. The paper makes use of and focuses on the data sets containing patient hospital records, patients’ identity and hospital code centre. To meet the desired aims, the paper uses two prominent methods of survival analysis including the Kaplan-Meier and Cox Proportional Hazard model. The result shows that survival time on the first treatment depends on mode of treatment and it quite low approximately 18 days for median time on hospital outpatient CAPD. Similarly, survival time on the second treatment is quite low about 24 days for the median time on hospital outpatient CAPD. It was also indicated that the survival time of renal dialysis patient depends on the number of treatments, the number of treatment changes, place of treatment, age and the first treatment

Analisis kelangsungan hidup (survival) merupakan suatu prosedur statistik yang digunakan untuk menganalisis data dimana variabel yang diteliti adalah waktu sampai terjadinya suatu kejadian. Salah satu distribusi yang banyak digunakan dalam menangani masalah survival adalah distribusi Weibull. Distribusi ini memiliki parameter skala (scale) dan bentuk (shape) yang mampu menyajikan keakuratan kegagalan dengan sampel yang kecil. Untuk mendapatkan model Weibull survival, kedua parameter tersebut perlu ditaksir. Menaksir parameter dapat dilakukan dengan dua pendekatan yaitu Bayesian dan klasik (frequentist). Tujuan dari artikel ini adalah untuk mengestimasi parameter distribusi Weibull dengan metode Bayesian dan maksimum likelihood. Kedua metode tersebut dibandingkan dan diaplikasikan pada data simulasi survival yang berdistribusi Weibull. Hasil yang diperoleh menunjukkan bahwa estimasi parameter dengan menggunakan metode Bayesian memberikan nilai taksiran yang lebih baik dibandingkan dengan metode maksimum likelihood berdasarkan nilai mean squared error (MSE).

Logistic regression ordinal is a regression model that can explain the relationship between predictor variables in the form of categorical data or continuous data with response variable is more than two categories with a scale of measurement that is level or sequence. In ordinal logistic regression, the frequency of occurrence in each response category is often very different, so it will affect the model's accuracy. Therefore, this study will model ordinal logistic regression with a dispersion of location effects, then applied to the nutritional status data of toddler in 2019 at the Pekkae Puskesmas, Barru Regency. The results obtained show that the ordinal logistic regression model with the dispersion of location effects is better than the usual ordinal logistic regression model for predicting the nutritional status data for toddlers in 2019 at Pekkae Puskesmas, Barru Regency based on deviance values. The factors that influence the nutritional status of toddler based on TB/U are gender, age, and height.
