Abstract

Kebisingan merupakan masalah lingkungan yang memiliki dampak negatif pada kehidupan sehari-hari. Di lingkungan kerja, kebisingan dapat menyebabkan risiko occupational noise-induced hearing loss. Salah satu sumber kebisingan di area bandara adalah kebisingan pesawat yang dapat memengaruhi kesehatan dan keselamatan para pekerja. Penelitian ini bertujuan untuk menganalisis tingkat kebisingan yang disebabkan oleh aktivitas bandara kepada pekerja dan merekomendasikan upaya pengelolaan kebisingan tersebut. Studi kasus dilakukan di Bandara Pondok Cabe yang dioperasikan oleh PT. Pelita Air Services untuk kegiatan sewa pesawat secara non-rutin. Hal ini memungkinkan untuk mengetahui perbedaan kebisingan yang ditimbulkan setiap jenis pesawat kepada pekerja. Pengukuran kebisingan di area kerja dilakukan menggunakan 4 (empat) buah sound level meter berdasarkan metode Nilai Equivalen, mengacu pada Keputusan Menteri Negara Lingkungan Hidup Nomor 48 Tahun 1996. Hasil pengukuran dibandingkan dengan Nilai Ambang Batas (NAB) yang ditetapkan dalam peraturan tersebut. Pengukuran dilakukan secara simultan di 4 (empat) lokasi, yaitu Appron Hanggar 2, Appron Hanggar 3, area Indopelita, dan di area kantor Hanggar 2. Tipe pesawat yang diukur adalah S76C++, BELL 412, dan ATR 72. Hasil pengukuran menunjukkan tingkat Leq10 di area Appron berkisar antara 81,61 dB(A) hingga 93,02 dB(A), sementara di area kantor berkisar antara 63,90 dB(A) hingga 70,78 dB(A). Hasil pengukuran kemudian dibandingkan dengan Nilai Ambang Batas (NAB) dalam peraturan yang berlaku. Berdasarkan hasil pengukuran, diketahui bahwa pekerja di area Appron terpapar kebisingan di atas batas NAB yang ditetapkan. Oleh karena itu, disarankan upaya pengendalian kebisingan pada tingkat primer, sekunder, dan tersier. Selain itu, perlindungan pendengaran dengan tingkat pengurangan kebisingan (Noise Reduction Rating/NRR) > 30 dB(A) diperlukan untuk memastikan kesehatan dan keselamatan para pekerja. Penelitian ini diharapkan dapat memberikan pemahaman yang lebih baik tentang masalah kebisingan di lingkungan kerja dan memberikan rekomendasi pengelolaan yang dapat membantu menciptakan lingkungan kerja yang lebih aman dan sehat, khususnya di lingkungan bandara.

Abstract

Turbidity is one of the main water quality parameters in drinking water quality. One way to reduce turbidity levels is by filtration. The filtration unit in the water treatment plant must use appropriate media so that the processed raw water meets World Health Organization (WHO) standards. WHO states that the turbidity of processed water before disinfection is 1 NTU. This research was conducted to know the efficiency of filtration processing with various media in reducing the concentration of turbidity in raw water. This study used three types of media, namely 50% silica sand with a mesh size of 12-16 and 50% silica sand with a mesh size of 8-12 (C), 100% silica sand with a mesh size of 12-16 (K), and 100% silica sand in mesh size. 8-12 (B). Porosity value for each sample C, K, and B is 0.412; 0.423; and 0.388. The detention time at maximum discharge for samples C, K, and B was 3.6, respectively; 3.76; and 3.45 minutes. The flow rates used for media samples C, K, and B were 4125 L/s and 2500 L/s, respectively. The removal efficiency produced by the highest turbidity was obtained in medium C with values of 90.8% and 89.9%, respectively. Meanwhile, media B gave the lowest turbidity removal efficiency, namely 86.3% and 86.4%. The results of all variations of the media used have met WHO standards, where the processed results have produced turbidity concentrations of 0.25 - 0.32 NTU.

Abstract

Asrama DLH Jagakarsa has a communal wastewater treatment plant (WWTP) that produces sludge that has not been treated. Asrama DLH residents directly apply the sludge from the communal WWTP as fertilizer for plants. Fecal sludge contains organic substances that provide nutrients to plants. However, there is a possibility that it still contains pathogenic bacteria and metals that can be harmful to plants. This research aims to utilize the fecal sludge from Asrama DLH Jagakarsa WWTP as organic fertilizer with additional ingredients in the form of humic acid. During fertilizer manufacturing, the bacteria and metals are removed. The analysis used includes the composting process conditions analysis, characteristics tests to determine the content of feces and fertilizers, and analysis of the application to plants. Analysis of the conditions in the composting process is the analysis of the pH value of organic fertilizers. Characteristic tests include soil variation (V1), WWTP sludge (V2), and organic fertilizer (V3). Analysis of the application of plant growth was carried out by testing the variation of soil 100% (P1), soil 80% + 20% fecal sludge (P2), and soil 80% + 20% organic fertilizer (P3). The laboratory analysis includes the analysis of nitrogen, phosphorus, potassium (NPP), and water content which will be compared with the quality standard of the Decree of the Minister of Agriculture Number 261 of 2019. The plant that is used as an indicator of the success of organic fertilizer in plant growth is the kale plant. The best value was obtained in the variation of organic fertilizer (V3), namely the NPP content and water content, respectively, which were 4.52%, 2.57%, 0.05%, and 19.84%. This shows that organic fertilizer increases NPP elements and plant growth.

Abstract

This study concerns the design of a waste management system using the Material Flow Analysis (MFA) method in the city of Tasikmalaya. TPA Ciangir is the only landfill in Tasikmalaya, and its storage capacity has reached its maximum, necessitating improvements in waste management. The aim of this design is to determine an appropriate waste management system that can be implemented in Tasikmalaya. Based on observations and interviews, waste collection at TPA Ciangir in Tasikmalaya is conducted in small amounts, leading to a significant amount of household waste not being collected daily, resulting in waste accumulation and minimal transport to waste processing facilities. According to Permen PU Number 3 of 2013 and SNI 19-2454-2002, waste collection from the source should be conducted at least once every two days. Therefore, an evaluation and redesign of the waste management system based on technical aspects are needed. The best system selection will be carried out using the Analytical Hierarchy Process (AHP) method, which will then be recommended for application at TPA Ciangir in Tasikmalaya. Based on the calculations using the AHP method, scenario 3 scored the highest, at 1.676, using composting processes, RDF, and TPST-3R. From the design results, a total waste reduction of 81% was achieved, aligning with the government's target of a 70% waste reduction by 2020.
