“…TGA and DSC analyses showed that baking soda exhibited 3% weight loss at a decomposition temperature of 134.2°C ± 0.9°C, with a melting temperature (T m ) of 173.2°C ± 2.0°C. The decomposition reaction of sodium bicarbonate in the range of 100°C°C to 180°C (373–453 K), shown in Equation , was both time‐ and temperature‐dependent

Volatile compounds produced during the fermentation of kimchi result in a sour taste and unpleasant odor. Here, we evaluated the utility of sodium bicarbonate (baking soda) as a natural deodorant in kimchi packaging. Baking soda decomposed into sodium carbonate, which showed superior deodorizing effects at 180°C, and aroma patterns were altered after deodorizing treatment with baking soda and heat-treated baking soda. Moreover, the numbers of off-odor compounds were decreased when using baking soda or heat-treated baking soda. In addition, the acetic acid removal rate increased with heat treatment of baking soda. Notably, the external shape and color of baking soda particles were not affected by heating. It was observed that an increase in the content of baking soda in the low-density polyethylene (LDPE)/baking soda composite films enhanced deodorizing effects. Finally, sensory evaluation confirmed that odor decreased with increased baking soda content. The findings demonstrate the potential value of baking soda and LDPE/baking soda composite films in kimchi packaging and reduction of off-odors.

“…Sumber zat berbau busuk mencakup produksi industri (misalnya, produksi asam fosfat, pupuk nitrogen, kertas, dan lainnya) (Boumnijel et al, 2016), instalasi pengolahan limbah, (Lewkowska et al, 2016;Zhou et al, 2016), tempat pembuangan sampah kota (Lucernoni et al, 2016), produksi ternak dan unggas (misalnya, kandang ayam, lumbung, dan lainnya) (Van der Heyden et al, 2015), proses pengolahan limbah, misalnya proses pembuatan kompos (Wang et al, 2015). Limbah yang dihasilkan dalam proses pembuatan es krim yang dikategorikan sebagai industri pengolahan makanan merupakan salah satu yang menghasilkan gas berbau busuk (Lee et al, 2013;Qamaruz-Zaman et al, 2015;Qamaruz-Zaman & Milke, 2012). Menurut Asmadi dan Suharno (2012), hampir semua jenis limbah cair industri pangan dapat diolah dengan sistem lumpur aktif.…”

The growing number of industries in Indonesia causes industrial waste to increase. Substances with upleasant smell from industrial waste can pollute the environment. Currently, not many people process and utilize industrial waste in the form of sludge left over from the WWTP process. The biofilter method will be very effective in handling air pollution because it has several advantages, among them are an easy and simple process, low investment and operational costs, and a relatively long operational time. The study began with the manufacture of incubation equipment and biofilter columns, testing the feasibility of the biofilter and incubation column, selecting fillers based on the results of a literature review, sampling fillers, preparing fillers, preparing samples of ice cream waste sludge from the ice cream industry in the Jababeka area, followed by analysis proximate sludge, analysis of ammonia gas in sludge with various variations of sludge weight and time, biofiltration process using coconut shell charcoal in order to obtain optimal variations in coconut shell charcoal size, then biofiltration using coconut shell charcoal briquettes with added zeolite content variations to determine the most effective filler material to remove odors. The results show that coconut shell charcoal with a particle size of 100 mesh is the most optimal biofilter filler for removing ammonia gas with an efficiency of 75% compared to a particle size of 20 mesh and 60 mesh which has an ammonia gas removal efficiency of 64% and 68%. Biofilter IV has the highest efficiency in removing ammonia gas, which is 90%. Keywords: Black soldier fly maggot, Biofilter, Coconut shell charcoal. Zeolite, Odor remover ABSTRAK Semakin banyaknya industri di Indonesia menyebabkan limbah industri semakin meningkat. Zat yang berbau dari limbah hasil industri dapat mencemari lingkungan. Saat ini belum banyak yang mengolah dan memanfaatkan limbah industri berupa sludge sisa proses IPAL. Metode biofilter akan sangat efektif dalam penanganan pencemaran udara karena memiliki beberapa keuntungan, diantaranya proses yang mudah dan sederhana, biaya investasi dan operasional yang rendah, serta waktu operasional yang relatif dapat bertahan lama. Penelitian diawali dengan pembuatan alat inkubasi dan kolom biofilter, pengujian kelaikan kolom biofilter dan inkubasi, pemilihan bahan pengisi berdasarkan hasil kajian literatur, sampling bahan pengisi, preparasi bahan pengisi, preparasi sampel sludge limbah es krim dari industri es krim di wilayah Jababeka, dilanjutkan dengan analisis proksimat sludge, analisis gas amonia pada sludge dengan berbagai variasi bobot sludge dan waktu, proses biofiltrasi menggunakan arang tempurung kelapa agar didapatkan variasi ukuran arang tempurung kelapa yang optimal, kemudian biofiltrasi menggunakan briket arang tempurung kelapa yang ditambahkan variasi kandungan zeolit untuk mengetahui bahan pengisi yang paling efektif menghilangkan bau. Hasil penelitian didapatkan bahwa arang tempurung kelapa dengan ukuran partikel 100 mesh adalah bahan pengisi biofilter yang paling optimal untuk menghilangkan gas amonia dengan efisiensi sebesar 75% dibandingkan dengan ukuran partikel 20 mesh dan 60 mesh yang memiliki nilai efisiensi penghilangan gas amonia sebesar 64% dan 68%. Biofilter IV memiliki nilai efisiensi paling tinggi dalam menghilangkan gas amonia yaitu sebesar 90%. Kata kunci: Black soldier fly maggot, Biofilter, Arang tempurung kelapa, Zeolit, Penghilang bau

“…Buffer systems used in spray air freshening products to neutralize odors may include for example, citrate or carbonate buffers. Neutralization of acid and amine odors to pH in the range of 5-8 by pH buffering converts these MOVOC to non-volatile salts, reducing or eliminating the odor [83].…”

Malodors, odors perceived to be unpleasant or offensive, may elicit negative symptoms via the olfactory system’s connections to cognitive and behavioral systems at levels below the known thresholds for direct adverse events. Publications on harm caused by indoor malodor are fragmented across disciplines and have not been comprehensively summarized to date. This review examines the potential negative effects of indoor malodor on human behavior, performance and health, including individual factors that may govern such responses and identifies gaps in existing research. Reported findings show that indoor malodor may have negative psychological, physical, social, and economic effects. However, further research is needed to understand whether the adverse effects are elicited via an individual’s experience or expectations or through a direct effect on human physiology and well-being. Conversely, mitigating indoor malodor has been reported to have benefits on performance and subjective responses in workers. Eliminating the source of malodor is often not achievable, particularly in low-income communities. Therefore, affordable approaches to mitigate indoor malodor such as air fresheners may hold promise. However, further investigations are needed into the effectiveness of such measures on improving health outcomes such as cognition, mood, and stress levels and their overall impact on indoor air quality.
