Cabai rawit merah (Capsicum frutescens L.) merupakan salah satu produk hortikultura Indonesia yang memiliki nilai ekonomi tinggi. Namun, cabai rawit merah memiliki umur simpan yang singkat dengan penurunan kualitas yang sangat cepat. Penelitian ini dilakukan untuk memperpanjang umur simpan dan menjaga kualitas cabai rawit merah menggunakan metode pengembusan gas ozon dengan dosis tertentu, dilanjutkan dengan penyimpanan pada beberapa jenis kemasan. Gas ozon dengan dosis 1, 3, dan 5 ppm digunakan sebagai agen disinfektan untuk mencegah pertumbuhan bakteri pada cabai rawit merah. Kemasan bermaterial PP, LDPE, dan PET digunakan sebagai wadah pengawetan. Sampel disimpan selama 14 hari untuk dilihat perkembangan kualitasnya. Kualitas cabai yang dianalisis adalah total bakteri mesofil aerobik (TBMA), kandungan capsaicin, penurunan massa, dan organoleptik pada penyimpanan jam ke 1, 72, 168, dan 336. Penggunaan gas ozon dengan konsentrasi 3 ppm yang dilanjutkan dengan penyimpanan pada kemasan PET memberikan hasil yang terbaik dalam memperpanjang umur simpan serta mempertahankan kualitas cabai rawit merah. Masa simpan cabai rawit merah dapat diperpanjang hingga 7 hari dibandingkan cabai rawit merah tanpa ozonasi. Pada aspek pengujian TBMA, didapatkan hasil kandungan bakteri yang lebih kecil hingga 89% dibandingkan sampel tanpa ozonasi. Penurunan massa juga dapat ditekan hingga 35,5%. Kualitas cabai rawit merah untuk aspek kandungan capsaicin tidak dipengaruhi baik konsentrasi ozon maupun kemasan penyimpanan.

Cayenne pepper (Capsicum frutescens L.) is one of Indonesia's horticultural products that has high economic value. However, red cayenne pepper has a very short shelf-life and quality loss. This research will discuss the ozonation of red cayenne pepper to extend the shelf life and maintain quality. The method used is the spraying of gaseous ozone on red cayenne pepper with a certain dose, followed by storage in several types of packaging. Gaseous Ozone with concentration of 1,3, and 5 ppm will be utilized as a disinfectant to keep microorganisms from contaminating horticultural products. As preservation containers, PP, LDPE, and PET packing materials will be utilized. The quality of the chilies to be analyzed were total aerobic mesophyll bacterium (TBMA), capsaicin content, weight loss, and organoleptic including observation of color, aroma, and texture. The use of ozone gas with a concentration of 3 ppm, followed by storage in PET packaging, provides the best results in extending the shelf life and maintaining the quality of red chili peppers. The shelf life of red chili peppers can be extended up to 7 days compared to non-ozone-treated red chili peppers. In terms of TBMA testing, a smaller bacterial content was found, up to 89% lower compared to samples without ozonation. Mass reduction can also be suppressed up to 35.5%. The quality of red chili peppers in terms of capsaicin content is not affected by both ozone concentration and storage packaging.

Ozon adalah gas dengan sifat oksidatif yang kuat yang dapat diproduksi dengan lucutan listrik dalam reaktor Dielectric Barrier Discharge (DBD). Penggunaan teknologi ozon sangat diminati karena kelebihannya dan aplikasinya di berbagai industri. Selain itu, produksi ozon dalam reaktor DBD juga memiliki potensi untuk menghasilkan produk samping nitrat sehingga bisa dianalisis potensi penggunaan reaktor DBD tersebut. Penelitian sebelumnya terkait sintesis ozon di reaktor DBD dengan penggunaan katalis memberikan hasil yang beragam. Penelitian ini menggunakan katalis berbasis silika gel dalam reaktor DBD. Penelitian ini melakukan uji produktivitas ozon dengan memvariasikan kondisi operasi dalam pembangkitan ozon di reaktor DBD. Setelah mendapatkan kondisi operasi terbaik, dilakukan pembangkitan ozon dengan katalis berbasis silika gel. Uji produktivitas nitrat tanpa menggunakan katalis dan dengan menggunakan katalis silika gel juga dilakukan. Penelitian ini bertujuan untuk menguji pengaruh variasi kondisi operasi dan katalis silika gel terhadap produktivitas ozon serta mengetahui kinerja produksi nitrat di reaktor DBD. Kondisi operasi terbaik untuk produksi ozon didapatkan di laju alir gas umpan 3 L/m dan tegangan listrik  15 kV pada reaktor 1 serta laju alir gas umpan 3 L/m dan tegangan listrik 4,4 kV pada reaktor 2, dengan hasil tertinggi 191,5 mg/jam. Produksi nitrat di reaktor yang digunakan menghasilkan konsentrasi hingga 34,53 ppm pada pH 10 dan 22,57 ppm pada pH 6.7 di larutan. Hipotesis awal mengantisipasi bahwa penggunaan katalis silika gel dapat meningkatkan produksi ozon, akan tetapi penggunaan katalis berbasis silika gel justru menurunkan produksi ozon dan nitrat dengan penurunan hingga 9-92% karena terpicunya dekomposisi ozon serta nitrogen oksida pada reaktor DBD.

Ozone is a highly reactive gas produced through electric discharge in a Dielectric Barrier Discharge (DBD) reactor. Its advantages have made ozone technology highly sought after across various industries. In the DBD reactor, ozone production can also lead to the generation of nitrate as a by-product, necessitating further analysis. Previous studies on ozone synthesis in DBD reactors using catalysts have yielded mixed results. This study will employ silica gel catalyst in a DBD reactor. The study aimed to test ozone productivity by varying operating conditions. Ozone generation was carried out using the silica gel-based catalyst. Nitrate productivity tests were also conducted, both without a catalyst and with silica gel catalyst. The study sought to examine the effect of operational variations and the silica gel catalyst on ozone productivity, as well as assess nitrate production in the DBD reactor. The optimal operating conditions for ozone production were achieved at a feed gas flow rate of 3 L/m and an electric voltage of 15 kV in reactor 1, and an electric voltage of 4.4 kV in reactor 2. These conditions resulted in the highest yield of 191.5 mg/hour. Nitrate production in the reactor yielded concentrations of up to 34.53 ppm at pH 10 and 22.57 ppm at pH 6.7. The initial hypothesis suggested that the use of silica gel catalysts would increase ozone production. However, the utilization of silica gel-based catalysts actually decreased ozone and nitrate production by up to 9-92% due to ozone and nitrogen oxides decomposition in the DBD reactor.

"The book presents results of CLUVA (CLimate Change and Urban Vulnerability in Africa), a large European Commission funded research project (2010-2013). The project aimed to develop a better understanding of the risks and impacts of climate change related hazards to African cities, assess their vulnerability to these risks, and identify innovative strategies for planning and governance to increase their resilience. For the first time, a systematic and groundbreaking study of this kind was applied in an inter- and trans-disciplinary approach. CLUVA was unique in that it combined: a top-down perspective of climate change modeling with a bottom-up perspective of vulnerability assessment; quantitative approaches from engineering sciences and qualitative approaches of the social sciences; a novel multi-risk modeling methodology; strategic approaches to urban and green infrastructure planning with neighborhood perspectives of adaptation. The book broadly follows the approach taken in the CLUVA project. First, the combined pressures of urbanisation and climate change on the African continent and the potential impacts these will have on cities are illustrated. Then, the vulnerability of three main elements of the urban system is explored: built structures and infrastructures, urban ecosystems and people. Rich material from five case studies is provided for in-depth discussion of the factors that make these elements vulnerable to climate change, while alternatives for increasing their adaptive capacity are outlined. Another section is dedicated to the role of urban planning and governance for climate change adaptation, which is approached from diverse perspectives. Finally, the different dimensions of the CLUVA project are synthesised to develop an outlook on future coping strategies for urbanisation and climate change in African cities. Leading researchers in the fields of vulnerability and urban planning have been invited to contribute complementary chapters. Thus, the book should be of wide interest to scholars in the field of urban vulnerability and climate change."
