Abstract

The purpose of this study was to determine employee performance in Child-Friendly Integrated Public Spaces, Kebon Jeruk District, West Jakarta, residents' satisfaction in Child-Friendly Integrated Public Spaces, Kebon Jeruk District, West Jakarta. and the role of Employee Performance on Citizen Satisfaction in Child- Friendly Integrated Public Spaces, Kebon Jeruk District, West Jakarta.This research method is a qualitative description through interviews with informants as key informants who explain or describe the effect of employee performance on citizen satisfaction in Child-Friendly Integrated Public Spaces, Kebon Jeruk District, West Jakarta. And through Focus Group Discussion (FGD) which is a group interview that emphasizes interaction on the topics discussed. This study also describes testing the validity of the data, the validity of the data or the credibility of the data, namely in observation, perseverance, discussion and study as well as analysis of the satisfaction of these residents.The results of the study showed that there was a value gap in the views of officials who were interviewed and discussed with community groups who were also interviewed by researchers. So the need for a researcher's perspective and confirms that performance is a substantial factor in creating maximum work. Thus the role of performance on citizen satisfaction in the Child-Friendly Integrated Public Space, Kebon Jeruk District, West Jakarta, is very important. Not only encouraging the creation of new values in understanding citizen satisfaction.

Abstract

Drinking water distribution work at PT. XYZ as a supporting part of the construction industry, involves a series of processes that have the potential to be dangerous and have high risks for workers. To ensure worker safety and health, identifying potential hazards and risks is important. The Job Hazard Analysis (JHA) method is an effective solution for carrying out this identification. This study aims to carry out the process of identifying potential hazards and risks and their control in the work of delivering drinking water supplies at PT. XYZ, using the JHA method. This approach allows systematic analysis of each step of the work, so that potential hazards can be clearly identified and the level of risk can be evaluated in depth. The results of the JHA analysis can be used as a basis for formulating effective control strategies to prevent accidents and injuries in the work environment. Based on the study results, the level of risk obtained at each stage of work before implementing controls varies but ranges between H12 or M9. After implementing risk control the residual risk value obtained is reduced to range between L2 to M6. The lowest residual risk value, namely L2, was obtained for the danger of negligence when checking vehicle oil from the previous value of M9 and the highest residual risk value of M6 was obtained for the danger of slippery floors when washing the vehicle from the previous risk value of M9.

Abstract

Dalam kegiatan praktikum di Laboratorium Manufaktur Politeknik Negeri Batam terdapat beberapa mesin bubut konvensional yang beroperasi. Namun dalam pengoperasinnya, terkadang terjadi masalah dengan proses produksi karena kerusakan mesin yang signifikan sehingga menyebabkan proses belajar menjadi terganggu. Tujuan studi ini adalah untuk mengidentifikasi komponen utama penyebab kerusakan pada salah satu mesin bubut konvensional dengan menggunakan metode Failure Mode and Effect Analysis (FMEA) dengan cara menghitung Risk Priority Number (RPN) dan memberikan rekomendasi. Dengan menghitung nilai RPN dapat diidentifikasi risiko kerusakan tertinggi dari komponen mesin bubut tersebut sehingga prioritas perawatan yang dibutuhkan dapat diketahui. Berdasarkan analisis, nilai RPN terbesar diperoleh sebesar 192 oleh gearbox mesin bubut, kemudian eretan pemutar sumbu x sebesar 36 dan kopling transmisi roda gigi sebesar 32. Karena seluruh komponen tersebut memiliki nilai RPN < 200, maka mitigasi risiko yang perlu dilakukan adalah dengan melakukan corrective maintenance namun untuk mencegah kerusakan mesin bubut sebelum terjadi dan memperkecil risiko gangguan pada praktikum, diperlukan peningkatan strategi yang lebih tepat pada preventive dan predictive maintenance.

Abstract

Kesalahan nilai pada pembacaan sensor tekanan dalam sistem ekskavator merupakan masalah yang sangat krusial dalam operasional alat berat. Kesalahan pembacaan tersebut akan berdampak terhadap nilai input pada sistem lainnya seperti pada sistem kontrol hidraulik dan menurunnya efisiensi operasional. Tujuan penelitian ini untuk mengidentifikasi penyebab, dampak, dan solusi pemulihan terhadap malfungsi sensor pada alat berat Komatsu PC130 milik PT. Rimba Prima Mas. Dengan menggunakan metode observasi, wawancara, dan analisis berbasis wiring diagram maka penelitian ini ditemukan bahwa kerusakan konektor wiring harness akibat faktor eksternal sehingga dampak yang ditimbulkan mencakup distribusi tekanan hidraulik yang tidak stabil dan penurunan performa alat berat. Solusi yang diterapkan yaitu dilakukan penyambungan sementara (temporary) untuk mendukung operasional mendesak dan terbukti efektif dalam memulihkan fungsi sensor dan sistem kontrol. Temuan ini juga menekankan pentingnya pemeliharaan preventif, perlindungan wiring harness, serta peningkatan kesadaran operator untuk mengurangi risiko kerusakan serupa di masa mendatang.

Abstract

This study investigates the effectiveness of a multimodal approach in improving students’ English reading comprehension at SMPN 10 South Tangerang during the 2025/2026 academic year. Involving 42 eighth-grade students, the research aimed to determine whether integrating various modes of learning—such as text, images, audio, and video—could enhance reading comprehension more effectively than traditional text-based instruction. A pre-experimental one-group pre-test and post-test design was used to measure students’ progress before and after the implementation of multimodal learning. Data were analyzed using a paired sample t-test to identify significant differences between the two tests. The results indicated a notable improvement, with the mean score increasing from 70.48 on the pre-test to 79.76 on the post-test, representing a gain of 9.28 points. The significance value (Sig. 2-tailed = 0.000) confirmed that the improvement was statistically meaningful. These findings demonstrate that multimodal instruction enhances comprehension by presenting information through multiple sensory channels, supporting diverse learning preferences, and creating a more engaging and interactive learning environment. The study concludes that the multimodal approach is an effective method for teaching reading comprehension in junior high school and recommends broader application in English classrooms to strengthen students’ motivation, understanding, and overall learning outcomes.

Abstract

Penelitian ini bertujuan mengimplementasikan Forward Kinematics pada robot lengan 4-DOF untuk pembuatan kopi otomatis. Prototipe menggunakan Arduino Uno, PCA9685, servo MG996R/MG90S, relay, dan pompa air mini. Gerakan diprogram dengan teach mode dan disimpan di EEPROM dengan kontrol open-loop. Metode Forward Kinematics dengan parameter Denavit-Hartenberg digunakan untuk menghitung posisi end effector dan divalidasi melalui pengukuran fisik pada 30 titik uji. Hasil menunjukkan error rata-rata 1,36 cm dengan tingkat keberhasilan 83% dan waktu eksekusi rata-rata 29,47 detik per siklus. Penelitian ini membuktikan metode Forward Kinematics dengan parameter DH efektif untuk validasi akurasi posisi robot lengan open-loop pada aplikasi F&B, serta prototipe dapat meningkatkan otomasi produksi skala kecil di industri F&B.
