Abstract

Spektrometer fotoakustik laser CO2 digunakan sebagai alat bantu diagnosis penyakitdengan cara mengukur konsentrasi gas aseton (C3H6O) pada pasien penderita diabetes mellitus tipe 2 dan kontrol ( relawan sehat). Sebagai wadah tempat penampung sampel gas hembus napas setiap pasien, digunakan sampel bag merk SKC yang terbuat dari bahan Tedlar polyvinyl fluoride film dengan ketebalan 3 mm dan volume maksimal 1 L. Pengukuran dilakukan pada garis laser 9P32. Konsentrasi gas aseton tertinggi pada pasien DM tipe 2 adalah (1050 ± 8) ppb dan yang terendah adalah (540 ± 6) ppb. Secara kuantitatif, hasil yang diperoleh membuktikan bahwa spektrometer FA laser CO2 konfigurasi intrakavitas bisa digunakan untuk mengukur konsentrasi gas aseton dalam sampel hembusan napas manusia dengan tingkat sensitivitas yang tinggi (ppb), yang dibuktikan dengan terukurnya perbedaan konsentrasi aseton antara relawan pasien DM dan relawan sehat.

Abstract

Efficient project delivery is a critical requirement for rural road rehabilitation programs, yet empirical evaluations of implementation efficiency remain limited. This study analyzes the time and estimated cost efficiency of the Papring Hotmix Road Rehabilitation Project in Kalipuro District, Banyuwangi, using a descriptive quantitative case study approach based on weekly and monthly project documentation. Project performance was measured by comparing baseline planning with field realization, supported by calculations of time efficiency, deviation analysis, and cost implication estimation derived from work-weight distribution. The project was completed in 55 days, significantly faster than the 120-day planned duration, resulting in a time efficiency of 54.17% and a maximum positive deviation of +76.32% at completion. Major work components: AC-WC (65.616%), AC-BC (18.249%), and aggregate base layer (12.436%), were executed intensively between Weeks 4 and 7, enabling a shortened execution period that suggests potential savings in indirect project costs such as overhead, labor, and field operations. Acceleration was driven by effective technical scheduling, early resource mobilization, optimized labor deployment, and strong contractor–consultant coordination. The findings highlight the importance of structured progress evaluation for improving scheduling and cost control in rural road rehabilitation projects. Future work should incorporate financial realization data and risk-productivity modelling to strengthen efficiency assessment in accelerated infrastructure delivery.
