Model Hybrid Fuzzy-Weighted Product Evaluasi Kinerja Honorer

Lia Umbari Putri, Rolly Yesputra, Jeperson Hutahaean
Abstract: Evaluasi kinerja pegawai honorer di instansi publik seringkali bergantung pada penilaian linguistik yang subjektif, sehingga memicu bias penilai dan keterbatasan akuntabilitas. Untuk mengatasi masalah tersebut, penelitian… n ini mengusulkan model hibrida Fuzzy-Weighted Product. Logika Fuzzy diterapkan untuk mentransformasikan istilah linguistik menjadi Triangular Fuzzy Numbers (TFN) dan skor tegas (crisp), sementara metode Weighted Product digunakan untuk mengagregasikan skor tersebut berdasarkan bobot multi-kriteria. Model ini dievaluasi melalui studi kasus yang melibatkan sepuluh pegawai honorer berdasarkan lima kriteria: disiplin, tanggung jawab, kualitas kerja, kerja sama, dan inisiatif. Hasil eksperimen menunjukkan bahwa model hibrida ini berhasil meminimalkan subjektivitas penilai dan menghasilkan perengkingan yang dapat direproduksi secara matematis. Analisis sensitivitas mengonfirmasi stabilitas hasil peringkat akhir, sehingga model Hibrida Fuzzy Weighted Product yang diusulkan ini sangat sesuai untuk digunakan sebagai kerangka kerja utama dalam sistem pendukung keputusan untuk penilaian kinerja di sektor publik.   Performance evaluation of honorary employees in public institutions often relies on subjective linguistic assessments, leading to evaluator bias and limited accountability. To address this, this paper proposes a Hybrid Fuzzy-Weighted Product (Fuzzy-Weighted Product) model. Fuzzy Logic is adopted to transform linguistic terms into Triangular Fuzzy Numbers (TFN) and crisp scores, while the Weighted Product method aggregates these scores based on multi-criteria weights. The model was evaluated using a case study of ten honorary employees across five criteria: discipline, responsibility, work quality, cooperation, and initiative. The experimental results demonstrate that the hybrid model successfully minimizes evaluator subjectivity and delivers mathematically reproducible rankings. A sensitivity analysis confirms the stability of the final rankings, making the proposed Hybrid Fuzzy–Weighted Product model highly suitable as a core framework for decision-support systems in public sector performance appraisal.

Wastewater Quality Test Using The MPN (Most Probable Number) Method To Detecte Total Coliform Bacteria

Ayu, Alfiana, Gultom, Endang Sulistyarini
Abstract: This study aims to Test Wastewater Quality Using the Mpn (Most Probable Number) Method to Detect Total COLIFORM Bacteria. This study uses laboratory analysis, which aims to provide an overview of the microbiological quality… ity of wastewater based on the presence and number of Coliform bacteria. The working principle of the Most Probable Number (MPN) method in detecting total Coliform bacteria in wastewater is carried out semi-quantitatively by detecting microbial growth through lactose fermentation which produces gas or turbidity in selective liquid media. The implementation procedure includes a presumptive test stage using Lactose Broth (LB) media, a confirmatory test with Brilliant Green Lactose Bile Broth (BGLB) media, and determining the final value by matching the combination of positive tubes with the standard MPN table. From the results of laboratory testing on three domestic wastewater samples (1224 AL, 1225 AL, and 1226 AL), it was found that all samples showed negative results with a combination of 0-0-0 tubes in the presumptive test. This indicates that the tested sample does not contain Total Coliform bacteria or has a value of less than 1000 MPN/100 mL, so that its microbiological quality is declared very good and has met the quality standard threshold set by the government through the Minister of Environment Regulation No. 5 of 2014 and PP RI No. 22 of 2021

A Theme–Rheme Analysis of International News Reports on Russia’s LGBT Policy

M. Asril Marpaung
Abstract: This study examines how thematic organization contributes to the construction of state power and social positioning in international news discourse. Drawing on Halliday’s Systemic Functional Linguistics, with a specific… c focus on Theme–Rheme structure, the study analyses a BBC news report published in November 2023 on the Russian Supreme Court’s decision to designate the so-called “international LGBT movement” as an extremist organization. Using a qualitative textual approach, the text is segmented into clauses and analyzed to identify patterns of thematic choice and progression. The findings reveal a consistent foregrounding of institutional actors, such as state authorities and legal bodies, in Theme position when reporting legal actions and policy decisions, while members of the LGBT community and civil society figures are predominantly thematized in clauses expressing reactions, personal experiences, and anticipated consequences. This asymmetric thematic distribution constructs a discourse in which state authority is positioned as the primary agent of action, whereas affected social groups are framed as respondents to institutional power. The study demonstrates that ideological meanings in news discourse may be realized implicitly through grammatical organization rather than explicit evaluative language, and it highlights the value of Theme–Rheme analysis for examining power relations in contemporary international news reporting.

Hypertension is one of the most common noninfectious diseases that affects the elderly. Hypertension is also a leading cause of serious complications such as stroke, heart failure, and kidney disease. Non-pharmacological approaches such as the Mindfulness-Based Stress Reduction (MBSR) method have been proven effective in lowering blood pressure by reducing stress and increasing self-awareness. This study aims to determine the effect of relaxation therapy with the MBSR method on reducing blood pressure among elderly patients with hypertension. This research employed a quantitative approach with a quasi-experimental design. The design used was a pre-test post-test design. The sample consisted of 30 elderly selected using purposive sampling based on inclusion and exclusion criteria. The study was conducted from April 14th to June 3rd, 2025. The intervention given was an MBSR treatment program for two months, eight sessions, including mindfulness meditation, breathing exercises, and relaxation techniques. Blood pressure measurements were taken before and after the intervention. The data were analyzed using the paired t-test. The results showed a significant decrease in systolic blood pressure of P< 0.000 and diastolic blood pressure with P < 0.011 after intervention. The average reduction in systolic blood pressure was 5.13 mmHg, and in diastolic blood pressure was 4.63 mmHg. These findings indicate that the MBSR therapy is effective in helping elderly individuals manage hypertension through stress reduction and enhanced self-awareness
