Abstract

The complexity of managing a project requires good and accurate planning. This is done to overcome the obstacles that arise in the implementation of project work. One of them is the obstacle of late project completion time. Program Evaluation and Review Technique (PERT) is a network model that is able to map the time of completion of activities. PERT is very useful for managing a project because it provides information relating to the completion of a project. The use of PERT method in this study provides the results of the completion time of type 72-storey residential building project based on a critical trajectory of 114 days. Through a statistical approach and assuming the completion of a normally distributed project the realistic time span of completion of the project is between 114 days to 124 days. While the probability of completion of the project during the time frame is between 50% to 99.9%.

Abstract

Untuk mencegah meningkatnya penularan Virus Corona atau COVID-19 pemerintah telah menetapkan bahwa satuan pendidikan yang berada di zona merah, oranye dan kuning dilarang melakukan proses pembelajaran tatap muka. Proses belajar dilaksanakan di rumah melalui pembelajaran jarak jauh (daring). Pada pembelajaran daring siswa dapat berinteraksi dengan guru menggunakan beberapa aplikasi salah satu diantaranya adalah Zoom Meetings. Guru bisa memanfaatkan berbagai fitur yang ada di aplikasi zoom untuk berkomunikasi secara dua arah dengan murid. Zoom merupakan aplikasi yang menyediakan layanan konferensi jarak jauh dengan menggabungkan konferensi video, pertemuan online, obrolan, hingga kolaborasi seluler. Selain itu, Zoom  juga dapat bekerja pada perangkat Android, iOS, Windows, dan Mac.

Abstract

TPM merupakan salah satu metode yang dapat digunakan untuk meningkatkan produktivitas dan efisiensi produksi perusahaan dengan menggunakan mesin/peralatan secara efektif. TPM juga bertujuan untuk meningkatkan efektivitas dengan cara meningkatkan fungsi dan kinerja mesin/peralatan yang digunakan dan mengeliminasi six big losses yang terdapat pada mesin/peralatan. Objek penelitian adalah mesin Moulding. Data yang digunakan data satu tahun terakhir yaitu bulan Juli 2019 - Juni 2020, diperoleh nilai overall equipment effectiveness (OEE) yang berkisar antara 45,49 % - 74,35 %. Nilai OEE terendah pada bulan Desember 2019 yakni sebesar 45,49 % yang mana pencapaian ini sangat jauh merosot dari bulan-bulan sebelumnya dan masih sangat kecil dibandingkan dengan nilai OEE target perusahaan sebesar 85% dimanah menurunnya nilai OEE dipengaruhi oleh faktor yang paling dalam six big losses adalah Idling dan minor stoppages berkisar dari 24,68% - 61,07 % , Reduced speed sebesar 9,09 % - 15,68 % dan Breakdown Loss sebesar 2,21% - 17,48. Sementara empat faktor lain berpengaruh kecil yaitu masih di bawah 10%.. Solusi untuk melakukan perbaikan dengan konsep Total Productive Maintenance (TPM) yang didalamnya meliputi autonomous maintenance.

Abstract

Schizophrenia is a chronic mental disorder that requires long-term treatment and is often accompanied by the risk of relapse. Relapse refers to the return of symptoms after a period of improvement or remission. This study aims to examine the effects of family support, medication adherence, and environmental support on relapse in schizophrenia patients. A quantitative approach was used to test the established hypothesis. Data were collected through a questionnaire that measured the variables of family support, medication adherence, and environmental support. Testing was carried out by analyzing validity, reliability, and R-Square analysis using the PLS (Partial Least Squares) model. The results showed that all instruments were valid and reliable, with Cronbach's Alpha and Composite Reliability values greater than 0.7. R-Square analysis indicated that family support, medication adherence, and environmental support collectively explained 63.3% of the variability in relapse among schizophrenia patients. Hypothesis testing demonstrated a positive and significant relationship between these three variables and schizophrenia relapse. This study confirms that family support, adherence to medication regimens, and positive environmental support can significantly reduce the risk of relapse in schizophrenia patients. Interventions focusing on improving these aspects may contribute to more effective management of schizophrenia and enhance patients' quality of life. ABSTRAKSkizofrenia adalah gangguan mental kronis yang membutuhkan perawatan jangka panjang dan sering kali disertai dengan risiko kekambuhan. Kekambuhan ini merujuk pada kembalinya gejala setelah periode perbaikan atau remisi. Penelitian ini bertujuan untuk mengevaluasi pengaruh dukungan keluarga, kepatuhan minum obat, dan dukungan lingkungan terhadap kekambuhan pasien skizofrenia. Penelitian ini menggunakan pendekatan kuantitatif untuk menguji hipotesis yang telah ditetapkan. Data dikumpulkan melalui kuesioner yang mengukur variabel dukungan keluarga, kepatuhan minum obat, dan dukungan lingkungan. Pengujian dilakukan dengan analisis validitas, reliabilitas, dan analisis R-Square menggunakan model PLS (Partial Least Squares). Hasil menunjukkan bahwa semua instrumen valid dan reliabel, dengan nilai Cronbach Alpha dan Composite Reliability > 0.7. Analisis R-Square menunjukkan bahwa dukungan keluarga, kepatuhan minum obat, dan dukungan lingkungan secara kolektif menjelaskan 63.3% dari variabilitas kekambuhan pada pasien skizofrenia. Uji hipotesis menunjukkan adanya hubungan positif dan signifikan antara ketiga variabel tersebut terhadap kekambuhan skizofrenia. Penelitian ini mengonfirmasi bahwa dukungan keluarga, kepatuhan terhadap regimen obat, dan dukungan lingkungan yang positif secara signifikan dapat mengurangi risiko kekambuhan pada pasien skizofrenia. Intervensi yang berfokus pada peningkatan aspek-aspek ini dapat berkontribusi pada pengelolaan skizofrenia yang lebih efektif dan peningkatan kualitas hidup pasien.

Abstract

Background: Nanofilled resin composites are popular for their aesthetics but are vulnerable to discoloration and surface degradation, particularly in acidic environments. Gochujang, a Korean chili paste, is increasingly consumed and may affect dental restorations. Objectives: To evaluate the effect of gochujang sauce immersion on the color stability and surface roughness of nanofilled resin composite. Methods: Thirty-three Filtek™ Z350 XT A3 samples were divided into three groups (n=11): immediate control, distilled water control, and gochujang treatment. The treatment group was immersed daily in a 1:1 gochujang-distilled water solution (16 h) and distilled water (8 h) for four days at 37°C. Color change (ΔE) was measured with a VITA Easyshade V spectrophotometer; surface roughness (Ra) with a Taylor Hobson Surtonic S-100. Results: Gochujang immersion significantly increased color change (ΔE, p<0.001) and surface roughness (Ra, p=0.009) compared to controls between groups (p<0.05). Conclusion: Gochujang immersion adversely affects both color stability and surface roughness of nanofilled resin composites.

Abstract

Introduction: Giomer is a resin-based restorative material consisting of prereacted glass ionomer (PRG) filler which can release fluoride. Carbonated beverages, popular beverages which contain acids that rich in H+ ions, can diffuse into the resin-based restoration and cause high solubility. Objective: To analyze the effect of immersion in carbonated drinks on water absorption and diametral tensile strength of giomer. Methods: Giomer was packed into a stainless-steel mold to obtain sample with diameter of 6.0±0.03mm and height of 3.0±0.09mm. The samples were divided into 2 groups for water absorption test and 3 groups for diametrical tensile strength test. Ten samples of giomer were soaked in artificial saliva for 4 days as a control group, 10 giomer samples were immersed in carbonated drinks for 6 hours, then replaced with artificial saliva for 18 hours and repeated for 4 days as a treatment group, and 10 samples of giomer were used as immediate group for direct diametral tensile strength test. Samples were incubated at 37°C. Results: Mann-Whitney test showed no significant difference (p>0.05) in giomer absorption between the control group (0.99±0.54%) and the treatment group (2.37±2.62%). One Way ANOVA test showed significant difference (p<0.05) in giomer diametral tensile strength among the immediate group (29.6±3.7MPa), the control group (51.1±3.9MPa) and the treatment group (44.8±5.3MPa). Conclusion: Immersion in carbonated beverages did not show significant difference with artificial saliva for the water absorption ability of giomer. However, the diametral tensile strength of giomer decreased after immersion in carbonated beverages for 24 hours.
