EVALUASI PERSYARATAN TERMAL BERDASARKAN REGULASI TENTANG KUALITAS UDARA

Dalam tulisan ini, akan disajikan suatu hasil evaluasi kualitas ruang kelas berdasarkan kondisi termalnya. Baku mutu tentang kondisi termal ruangan yang diacu dalam tulisan ini adalah suatu regulasi persyaratan kenyamanan termal. Metode yang digunakan dalam evaluasi adalah pengukuran langsung di dalam ruang kelas yang sedang digunakan dalam kegiatan belajar-mengajar. Analisis dilakukan berdasarkan perbandingan antara hasil pengukuran lapangan dengan baku mutu. Kesesuaian akan menjadi dasar untuk mencari peluang tindakan perbaikan yang dapat dilakukan pada ruangan tersebut. Sebaliknya, ketidaksesuaian yang terjadi akan menjadi dasar rekomendasi tindakan koreksi yang dapat dilakukan. Hasil evaluasi ini bersifat unik karena merupakan hasil pengukuran lapangan pada ruang kelas yang efektif dipergunakan. Kondisi cuaca secara umum, kondisi struktur bangunan, serta aktivitas dalam ruangan menjadi faktor yang dipertimbangkan dalam analisis. Hasil analisis menunjukkan bahwa ruangan dengan karakteristik struktur tidak permanen, memiliki kondisi udara yang tidak sesuai dengan karena temperatur ruang berada 2,5°C s.d 7,3°C diatas persyaratan. Sementara itu, kondisi kelembaban masih dalam batas yang diperbolehkan oleh persyaratan

PELATIHAN HARGA POKOK PRODUKSI UNTUK MENINGKATKAN PENGELOLAHAN USAHA

Peran Usaha Mikro Kecil dan Menengah (UMKM) memiliki kontribusi yang sangat penting terhadap perekonomian Indonesia yaitu perluasan kesempatan kerja. Dalam menciptakan usaha bukan hanya diperlukan kemampuan berproduksi tapi juga kemampuan dalam mengelolah usaha tersebut. Laporan harga produksi adalah salah satu informasi yang berguna bagi wirausaha dalam menjalankan usahanya. Menentukan harga pokok produksi diperlukan agar memiliki pengetahuan dalam mengelolah biaya. Umumnya masyarakat Desa Koper belum mempunyai memiliki pengetahuan dalam menghitung harga pokok produksi. Berdasarkan kondisi tersebut, team PKM dari Universitas Pamulang melakukan pelatihan laporan harga pokok produksi. Dari hasil evaluasi didapat bahwa terjadi peningkatan pengetahuan peserta PKM tentang harga pokok produksi serta yang berkaitan dengan hal tersebut. Diharapkan setelahnya dapat dipraktekan dalam menjalankan UMKM sebagai bahan pertimbangan penentuan harga jual serta keputusan lain

Real-time wireless temperature measurement system of infant incubator

The internet of things (IoT) has allowed for ubiquitous measurement. Infant incubator temperature is one of crucial parts that need to be measured, especially for the stability and uniformity temperature. Based on the interpretation of IEC 60601-2-19, we proposed measurement method using IoT with the message queue telemetry transport (MQTT). In the 10,000 packet, the result shows the quality of service (QoS) level 2 of the system has the highest delay, however it has the lowest packet loss data than the other QoS. For 1 hour, the uniformity result and stability can fulfill the standards. Uniformity of 32°C, the lowest difference is point C with 0.32 °C, and the highest difference is point B with 0.75 °C. Uniformity of 36 °C, the lowest difference is point B with 0.27 °C, and the highest difference is point C with 0.79 °C. The stability of 32 °C and 36 °C is 0.32 °C and 0.44 °C, respectively. Moreover, the Kruskal Wallis test shows the highest difference average from point M is point A and B. It occurred because of the point A and B located far from the heater part, so the point A and B colder than point C

Advanced Control for Quadruple Tank Process

In the realm of control systems, the last three decades have witnessed significant advancements in Model Predictive Control MPC), an advanced technique renowned for its ability to optimize processes with constraints, handle multivariate systems, and incorporate future references when feasible. This paper introduces an innovative offset-free MPC approach tailored for the control of a complex nonlinear system—the Quadruple Tank Process (QTP). The QTP, known for its deceptively simple yet challenging multivariate behavior, serves as an ideal benchmark for evaluating the efficacy of the proposed algorithm. In this work, we rigorously compare the performance of the PID and MPC controller when applied to both linear and nonlinear models of the QTP. Notably, our research sheds light on the advantages of MPC, particularly when confronted with constant disturbances. Our novel algorithm demonstrates exceptional capabilities, ensuring error-free tracking even in the presence of persistent load disturbances for both linear and nonlinear QTP models. Compared to the PID control, the proposed method can reduce the overall set point tracking error up to 32.1%, 27.6%, and 38.54% using the performance indices ISE, ITAE, and IAE, respectively, for the linear case. Furthermore, for the nonlinear case, the overall set point tracking error reduction is up to 93.4%, 94.9%, and 91.5%. This work contributes to bridging the gap in effective control strategies for nonlinear systems like the QTP, highlighting the potential of offset-free MPC to enhance control and stability in a challenging process industry involving automatic liquid level control
