Pengolahan Limbah Urine Sapi Menjadi Pupuk Organik Cair (POC) dengan Metode Fermentasi Aerasi untuk Mendukung Aktivitas Praktikum di Jurusan Peternakan Politeknik Negeri Jember

Urine sapi merupakan salah satu penyumbang limbah terbesar pada sektor peternakan. Hal ini tentu saja dapat menurunkan kualitas lingkungan sekitar jika limbah yang dihasilkan setiap hari tersebut tidak diolah. Politeknik Negeri Jember memiliki TEFA sapi perah yang juga memiliki hasil samping berupa urine sapi dalam jumlah besar setiap harinya, sehingga diperlukan adanya pengolahan urine sapi. Produk dari salah satu teknologi inovasi dalam pengolahan limbah urine adalah pupuk organik cair (POC). Urine sapi yang dicampur dengan bahan tertentu dapat dijadikan pupuk organik cair setelah melewati serangkaian proses fermentasi. Proses fermentasi aerasi dapat digunakan dalam pembuatan pupuk organik cair.  POC hasil fermentasi metode aerasi memiliki potensi nutrisi yang baik sebagai pupuk, tetapi dari sisi mikrobiologi masih belum aman digunakan, sehingga diperlukan optimalisasi proses fermentasi untuk menekan patogen tanpa mengorbankan kandungan hara

Design and Development of a Motorcycle Brake Fluid Temperature Monitoring System to Prevent The Vapor Lock Conditions

One of the braking system problems in a motorcycle is a vapor lock. Vapor lock can occur when brake fluid, the fluid that helps the brake piston movement, experiences increased heat until it evaporates. Vapor lock can occur when the vehicle has been used due to the high-performance load of the braking system. This research aims to create a brake fluid temperature measuring and monitoring tool. By monitoring the brake fluid temperature, vapor lock conditions can be anticipated. To conduct this research, several materials are required, including K-type thermocouple sensor, Arduino Mega module, RGB bright LED, buzzer, and LCD. The accuracy value of the sensor will be calculated. The results showed that under all conditions, the sensor accuracy had a good value, above 98%. When implemented on a motorcycle, brake fluid temperature conditions are divided into four ranges: 29 °C to 124 °C; 125 °C to 134 °C; 135 °C to 145 °C; and above 145 °C. The results of the implementation on the motorcycle were successful overall, where the condition of each actuator changed when the temperature range of the motorcycle's brake fluid also changed. For example, at the highest temperature, the RGB bright LED lights up Red, the buzzer sounds continuously, and the status message on the LCD is “Bahaya!”

Feature Requirement With Human-Centered Design Approach to Developing A Psychological-Based HIV

HIV cases among adolescents in Indonesia have been on the rise recently. Moderate to severe depressive symptoms are reported to be experienced by adolescents living with HIV, which coincides with this increase in cases. This suggests that it is essential to initiate strategic initiatives to enhance the efficacy of the initial screening process by implementing application-based HIV risk group identification through the use of psychological approaches. Designing a user interface that is appropriately structured and meets user requirements is crucial to ensuring the effectiveness of the application being developed. This investigation involved the assessment of feature requirements by HIV disease counselors and psychologists in accordance with the Human-Centered Design (HCD) methodology. Counselors who specialize in HIV disease contribute to the query elements utilized in the initial screening assessment. Meanwhile, psychologists contribute to the approval of the questions utilized as an initial screening test, which affects the psychological well-being and accuracy of adolescent users. The stages adopted for the implementation of HCD were modified in accordance with ISO 9241-210. This research generated user personas, use case diagrams, and the User Interface (UI) design for the VitaMind application, which is primarily designed for pre-test screening. This is a multiplatform application that comprises both web-based and mobile components. This application design has been tested using the system usability scale (SUS) method and produced an accuracy score of 86.1%. The primary contribution and novelty of this research lies in the application of Human-Centered Design principles to the development of a mental health-focused, pre-test HIV screening application tailored for students. Usability testing, employing the System Usability Scale (SUS) method, yielded results demonstrating a high degree of usability

Development of a Web-Based Self-Health Screening Kiosk for The Participants of Chronic Disease Management Program (PROLANIS)

Current PROLANIS screening workflows at primary healthcare facilities remain predominantly manual and complex, characterized by lengthy registration processes, laboratory examinations, medical consultations, therapeutic exercises, health education sessions, and pharmacy visits. These inefficiencies result in prolonged patient queues, duplicate documentation, delayed data aggregation, and excessive workload for healthcare personnel, ultimately compromising program effectiveness and participant satisfaction. This study addresses these challenges through the development of a web-based self-health screening kiosk utilizing a Research and Development (R&D) approach with a prototyping model. System evaluation focused specifically on user interface/experience (UI/UX) feasibility, rather than clinical effectiveness, involving six PROLANIS officers from Sidorejo Lor and Sidorejo Kidul Community Health Centers using a structured assessment instrument. Results yielded an average score of 4.0 (out of 5), indicating good design consistency, responsiveness, and functionality, though improvements remain necessary in ease of use and visual layout. The prototype demonstrates potential to enhance PROLANIS efficiency but requires broader clinical validation and system integration testing

Speech fluency and accuracy as indicators of academic speaking proficiency

Previous studies on the assessment of academic speaking skills in English as a Foreign Language (EFL) context have predominantly emphasized fluency and accuracy as key performance criteria, yet limited attention has been given to empirically examining their suitability as indicators of overall academic speaking proficiency, particularly at the university level. Addressing this gap, the present study aims to investigate the extent to which fluency and accuracy function as key indicators in assessing university-level EFL students’ academic speaking proficiency. A quantitative research method with a correlational design was employed, involving 60 students enrolled in an Academic Speaking course who were selected using purposive sampling. Data were collected through recordings of academic presentation tasks and analyzed using an assessment rubric based on the Common European Framework of Reference (CEFR). The results revealed a significant positive correlation between levels of fluency and accuracy and overall academic speaking proficiency scores. These findings provide empirical evidence of the suitability of fluency and accuracy as indicators in academic speaking assessment. The study highlights the importance of integrating assessment rubrics that place greater emphasis on fluency and accuracy in the teaching and evaluation of academic speaking skills

Broiler Response To Different Energy Levels Within The Same Protein Levels On Feed Intake, Body Weight Gain, And Feed Conversion

Abstract: to examine how different energy levels in the same protein affect feed intake, body weight gain, and feed conversion. The study used treatments in the form of differences in metabolizable energy levels at the same protein level, namely 19%. The feed treatments were as follows: T1 = 2800 kcal/kg, T2 = 2900 kcal/kg, T3 = 3000 kcal/kg, and T4 = 3100 kcal/kg. A total of 100 one-day-old unsexed broiler chickens were divided into four treatments, each of which was repeated five times. The feed treatment was administered from 1 to 35 days of age. The experimental design used a completely randomized design, followed by Duncan's test. The research parameters were feed intake, weight gain, and feed conversion. The results showed that increasing metabolic energy reduced feed intake and feed conversion (p<0.05) and increased weight gain (p<0.05). Feed intake was lowest at an energy level of 2900 kcal/kg, while weight gain was highest at an energy level of 3100 kcal/kg. Broiler performance was optimal at a protein level of 19% and a metabolizable energy level above 2900 kcal/kg

ESP in Indonesian vocational high school: A need analysis of office administration students

Although English instruction in Indonesian vocational high schools is formally framed as ESP, teaching materials and practices often remain generic and poorly aligned with students’ occupational needs. Addressing the limited ESP needs-analysis research on Office Administration programs, particularly in regional contexts, this study examines the English learning needs of vocational high school students in South Kalimantan, Indonesia. Employing a descriptive needs-analysis design, the study involved 70 Grade X students selected through total population sampling. Data were collected using a validated questionnaire based on established ESP and needs-analysis frameworks and were analyzed using descriptive statistics. The findings indicate that students primarily require English for workplace oral communication, yet their proficiency remains at a basic level, with significant deficiencies in speaking, listening, and vocabulary mastery, as well as grammar-related difficulties in writing. These results reveal a clear mismatch between students’ communicative goals and their current language competence. The study highlights the necessity of ESP-oriented English instruction that prioritizes communicative tasks, job-related vocabulary, and functional grammar relevant to administrative contexts. The findings offer empirical guidance for curriculum design and instructional material development in vocational education
