Evaluasi Risiko Keselamatan Kesehatan Kerja Lingkungan Aktivitas Departemen Produksi Dan Maintenance Mold Menggunakan Pendekatan HIRADC. Dibimbing oleh NURUL JANNAH. Penelitian ini bertujuan merumuskan rekomendasi pengendalian risiko kecelakaan kerja pada Departemen Produksi dan Maintenance Mold di industri manufaktur furnitur plastik. Aktivitas kerja pada kedua departemen memiliki potensi risiko tinggi karena melibatkan mesin berat, mold, dan alat kerja berbahaya, yang telah menyebabkan insiden seperti luka potong, cedera mata, dan luka jepit. Penelitian menggunakan metode Job Safety Analysis (JSA) dan Hazard Identification, Risk Assessment and Determining Control (HIRADC) dengan matriks risiko AS/NZS 4360:2004 berdasarkan parameter likelihood dan severity. Data diperoleh melalui observasi, wawancara, serta dokumen perusahaan. Hasil penilaian risiko digunakan untuk menyusun rekomendasi pengendalian berdasarkan hierarki pengendalian risiko. Luaran penelitian meliputi dokumen JSA, HIRADC, rekomendasi pengendalian risiko, peta hazard, dan pembaruan denah evakuasi. Kata kunci: HIRADC, JSA, kecelakaan, pengendalian, risiko.; This study aims to formulate recommendations for controlling occupational accident risks in the Production and Mold Maintenance Departments of a plastic furniture manufacturing company. Work activities in both departments have a high potential for occupational accidents because they involve heavy machinery, molds, and hazardous work equipment, resulting in incidents such as cuts, eye injuries, and pinch injuries. The study employs the Job Safety Analysis (JSA) and Hazard Identification, Risk Assessment and Determining Control (HIRADC) methods, using the AS/NZS 4360:2004 risk matrix based on the likelihood and severity parameters. Data were collected through observations, interviews, and company documents. The risk assessment results were used to develop risk control recommendations based on the hierarchy of risk controls. The outputs of this study include JSA and HIRADC documents, risk control recommendations, a hazard map, and an updated evacuation map.

Kondisi tersebut menyebabkan beban hidrolis dan beban pencemar yang masuk ke beberapa unit pengolahan sehingga proses pengolahan tidak berlangsung secara optimal. Penelitian ini bertujuan mengevaluasi kondisi eksisting IPAL domestik serta menyusun redesign sistem pengolahan menggunakan pendekatan Integrated Fixed Film Activated Sludge (IFAS) yang mengombinasikan pertumbuhan biomassa tersuspensi dan biomassa melekat untuk meningkatkan retensi biomassa. Penelitian dilakukan melalui observasi lapangan, pengumpulan data operasional, analisis kualitas air limbah, serta perhitungan desain berdasarkan debit aktual sebesar 18,6 m³/hari. Evaluasi dilakukan terhadap kondisi eksisting unit pengolahan, karakteristik air limbah, kapasitas unit, dan kesesuaian sistem terhadap kondisi underload sebagai dasar penyusunan redesign.; The domestic wastewater treatment plant (WWTP) at the Head Office of PT Pertamina (Persero) is experiencing an underload condition due to decreased building activity, resulting in a wastewater flow rate lower than the design capacity. This condition causes reduced hydraulic and pollutant loads entering several treatment units, resulting in suboptimal treatment performance. This study aims to evaluate the existing domestic WWTP and develop a redesign of the treatment system using the Integrated Fixed Film Activated Sludge (IFAS) approach, which combines suspended-growth and attached-growth biomass to increase biomass retention. The study was conducted through field observations, operational data collection, wastewater quality analysis, and design calculations based on an actual wastewater flow rate of 18.6 m³/day. The evaluation covered the existing treatment units, wastewater characteristics, unit capacities, and system suitability under underload conditions as the basis for the redesign.

Penelitian bertujuan menganalisis dampak lingkungan proses produksi es rasa buah mangga menggunakan metode Life Cycle Assessment (LCA) dengan batasan sistem gate to gate sesuai ISO 14040:2016 dan ISO 14044:2017. Penilaian dampak dilakukan menggunakan metode CML-IA Baseline dan Cumulative Energy Demand (CED) pada perangkat lunak OpenLCA. Hasil penelitian menunjukkan nilai dampak Acidification Potential sebesar 48,44 kg SO2 eq, Eutrophication Potential sebesar 29,38 kg PO4³? eq, Global Warming Potential sebesar 6.663,25 kg CO2 eq, Ozone Layer Depletion sebesar 2,18 × 10-4 kg CFC-11 eq, CED Non-Renewable sebesar 1.4454,22 MJ-eq, dan CED Renewable sebesar 745,18 MJ-eq. Unit proses cold storage merupakan kontributor terbesar pada hampir seluruh kategori dampak.; The ice cream processing industry is one of the food sectors with the potential to cause environmental impacts due to its high consumption of energy and raw materials, as well as its refrigeration processes. This study aims to analyze the environmental impacts of the production process of mango-flavored fruit ice using the Life Cycle Assessment (LCA) method with a gate to gate system boundary in accordance with ISO 14040:2016 and ISO 14044:2017. The impact assessment was conducted using the CML-IA Baseline and Cumulative Energy Demand (CED) methods in OpenLCA software. The results showed an Acidification Potential impact of 48,44 kg SO2 eq, Eutrophication Potential of 29,38 kg PO4³? eq, Global Warming Potential of 6.663,25 kg CO2 eq, Ozone Layer Depletion of 2,18 × 10-4 kg CFC-11 eq, Non-Renewable CED of 14.454,22 MJ-eq, and Renewable CED of 745,18 MJ-eq.

UMKM Kampung Batik Cibuluh Bogor belum memiliki pengolahan air limbah batik. Kulit mangga yang mengandung pektin berpotensi dimanfaatkan sebagai biokoagulan alami untuk menurunkan kadar pencemar. Penelitian ini bertujuan menganalisis karakteristik kimia biokoagulan kulit mangga serta menilai efektivitasnya dalam menurunkan konsentrasi pencemar. Biokoagulan dibuat melalui ekstraksi pektin menggunakan asam sitrat 7% kemudian dianalisis menggunakan Fourier Transform Infrared Spectroscopy (FTIR). Penelitian dilakukan dengan 5 variasi dosis melalui uji jar test dan diaplikasikan dalam bentuk bubuk. Hasil analisis FTIR mengidentifikasi gugus hidroksil, metil, garam asam uronat, karboksilat, dan fingerprint polisakarida sebagai karakteristik khas pektin. Biokoagulan menurunkan TSS dan kekeruhan dengan efektivitas 55% dan 3% pada dosis 175 mg/L, sedangkan TDS mencapai efektivitas 27% pada dosis 200 mg/L. Penurunan TSS belum memenuhi baku mutu 40 mg/L sehingga diperlukan optimasi dosis.; Batik wastewater contains pollutants including Total Dissolved Solids (TDS), turbidity, Total Suspended Solids (TSS) that can damage the environment. The Batik Cibuluh Village SME in Bogor has not yet implemented batik wastewater treatment. Mango peel containing pectin can be utilized as a natural biocoagulant to reduce pollutant concentrations. This study aimed to analyze the chemical characteristics of mango peel biocoagulant and evaluate its effectiveness in reducing pollutant concentrations. The biocoagulant was prepared through pectin extraction using 7% citric acid and analyzed using Fourier Transform Infrared Spectroscopy (FTIR). The study was conducted using five dosage variations through a jar test and applied in powder form. FTIR analysis identified hydroxyl, methyl, uronic acid salt, carboxylate, and polysaccharide fingerprint groups as characteristic features of pectin. The biocoagulant reduced TSS and turbidity, with effectiveness values of 55% and 3%, respectively, at 175 mg/L, while TDS reached 27% at 200 mg/L. TSS reduction did not meet the 40 mg/L standard, requiring dosage optimization. Thu, 01 Jan 2026 00:00:00 GMT http://repository.ipb.ac.id/handle/123456789/179537 2026-01-01T00:00:00Z
