Abstract

Necessary approaches are needed to reduce the impact of rejected exported Indonesian seafood due to chemical contamination. This study aims to prioritize food and chemical pairs in the rejected fishery products. The rejection data from three major export destinations: the United States, the European Union, and Japan in 2017-2019 were used. Combinations of food and chemicals were developed and screened, followed by constructing a risk matrix to prioritize the pairs based on health and economic impact. Based on the health impact, a tuna–histamine pair was considered medium risk along with other commodities pairing with heavy metals. Tuna is the most exported seafood and suffers from the most loss; hence it has the highest score for severity and likelihood of economic impact. The combination of health and economic-based prioritization suggested that tuna–histamine was the top priority for immediate mitigation. The second priority consisted of shark–mercury, swordfish–mercury, octopus–cadmium; mahi-mahi–histamine was the third priority. This prioritization can assist risk managers in determining the order of commodities be acted upon based on health and economic considerations to enhance global market access.

Abstract

Ochratoxin A (OTA) is a nephrotoxic and carcinogenic mycotoxin that can be found in coffee. This study aimed to obtain the processing steps commonly applied by coffee shops in Indonesia, calculate the level of OTA in coffee bean and ground coffee, and the risk estimate of OTA exposure from ground coffee in Indonesia. The processing steps were determined through an online survey while the level of OTA in coffee was calculated from available references. The consumption level of ground coffee was determined from the Indonesia total diet study report and the exposure assessment was carried out by deterministic approach. The risk estimates were expressed as % risk towards provisional tolerable weekly intake (PTWI) and margin of exposure (MOE). Based on the survey of coffee shops (n=20), ground coffee is commonly processed using dry method consisting of cherries sorting, sun drying, roasting and grinding. Ground coffee was the most common coffee consumed by adults. Based on references from countries with climate similar to Indonesia, the level of OTA in coffee bean ranged from 0.033 to 168 μg/kg with an average of 12.25 μg/kg and 0.018-55 μg/kg in ground coffee averaging at 5.60 μg/kg. The individual exposure to OTA from drinking coffee is 0.014-0.744 ng/kg bw/day. The risk estimates shows that risk of ochratoxin A from ground coffee consumption is low, with risk percentage of <100 % provisional tolerable weekly intake (PTWI) and a MOE of higher than 10000 for all age groups. The study suggested that adults (19-55 years) have higher exposure and risk than the other age groups.

Abstract

Ozone produced using plasma technology can act as an antimicrobial agent that could be applied in a sterilization process. A Double Dielectric Barrier Discharge (DDBD) machine has ability to produce ozone in sufficient amount for microbial inactivation. The objective of this study is to characterize the ozone distribution expressed as dissolved ozone in distilled water and coconut water produced using a DDBD machine. The information can be useful for industries to design a commercial sterilization process. The results shows that an oxygen flow rate of 0.2 L/min produces the highest ozone concentration, i.e. 3440 mg/L. In addition, the capacity of the machine is relatively similar to all off oxygen flow rate, i.e., 41.28-43.2 g/hour. The oxygen flow rate of 0.2 L/min produces the highest dissolved ozone concentration, i.e. 0.42 mg/L distilled water. This oxygen flow rate is followed by its best kinetic model based on its linear portion during dissolved ozone penetration. A zero order model could describe this penetration process well, including its best k value of 0.0292 mg/L per minute with the highest dissolved ozone concentration among other oxygen flow rates. Besides, distilled water could represent dissolved ozone penetration in coconut water. Ozone gas and dissolved ozone concentration have possitive corellation with R-square value of 0.8934.

Abstract

Bakteri patogen pangan bukan pembentuk spora dapat memasuki kondisi nongrowing ketika berada dalam kondisi yang tidak mendukung pertumbuhannya, seperti kondisi nutrisi rendah, pH rendah, dan suhu rendah. Salah satu bentuk nongrowing bakteri adalah kondisi VBNC (viable but nonculturable). Bakteri dalam kondisi VBNC tidak dapat membentuk koloni pada media agar yang rutin digunakan untuk enumerasi bakteri, meskipun demikian bakteri ini masih memiliki viabilitas (integritas seluler), dan mampu melakukan aktivitas metabolik yang ditandai dengan kemampuan mengekspresikan protein, respirasi, dan adanya aktivitas enzimatik intraseluler. Dalam kondisi VBNC tersebut, bakteri khususnya patogen, yang terdapat di dalam pangan akan menimbulkan bahaya kesehatan. Hal ini mengkhawatirkan, karena metode pengkulturan yang digunakan mengendalikan keamanan pangan diduga tidak mampu mendeteksi bakteri patogen pangan yang berada dalam kondisi VBNC. Estimasi jumlah bakteri patogen pada pangan yang lebih rendah dari sebenarnya, dan kegagalan mengidentifikasi bakteri patogen pada sampel pangan saat dikulturkan pada media agar cawan, menimbulkan bahaya bagi kesehatan, apabila pangan tersebut dikonsumsi. Oleh karena itu, keberadaan kondisi VBNC bakteri patogen pangan perlu dipelajari lebih lanjut.

Abstract

Foodborne pathogens bacteria may enter a nongrowing state under unfavorable conditions for their growth, such as low nutrient, low pH, and low temperature. One of the nongrowing states of bacteria is a viable but nonculturable (VBNC) state. Bacteria in this VBNC condition can not form colony on agar medium daily used for enumeration of bacteria, despite, these bacteria still have viability (cellular integrity), and able to do metabolic activity like the ability to express protein, to respirate, and to do intracellular enzymatic activity. Under the VBNC state, bacteria especially the pathogens which are present in food will raise a health risk. This is worrying, because the culture method used to control food safety is thought unable to detect foodborne pathogens that are in VBNC state. Estimation of the number of pathogenic bacteria in food that is lower than the actual number, and the failure to identify foodborne pathogenic bacteria in food samples when cultured in agar plates, raise health concerns, if the food is consumed. Therefore, the presence of VBNC state in foodborne pathogenic bacteria needs to be studied further.

Abstract

Tempe is a nutritious, healthy, and affordable food. Tempe production is simple, but less hygienic under traditional production, therefore can have inconsistent quality, safety, and reduce consumer interest. In Indonesia, Good Manufacturing Practices (GMP) implementation is a basic requirement for food industries, including tempe industries, in producing safe food products. It is yet unknown the availability of GMP tempe, especially in Jabodetabek area and how it relates to consumers' willingness to purchase. This study aimed to determine the availability of GMP tempe in Jabodetabek and to analyze the knowledge, perceptions, and willingness of Jabodetabek consumers to purchase GMP tempe. The research method included observing the GMP-applying tempe availability and surveying consumers' knowledge and willing-ness to purchase GMP-applying tempe using google form questionnaire. Data analysis used descriptive and Spearman correlation test. The results showed that GMP-applying tempe was available in almost half (38%) of market sample in Jabodetabek. GMP-applying tempe was available in small number (1%) of traditional markets and most (72%) supermarkets. Most of the respondents (54%) were used to consuming good quality tempe. Almost all respondents (78%) understood the advantage of GMP-applying tempe. Most respondents (67%) were willing to purchase GMP-applying tempe with a maximum price increase of 20% from regular tempe.

Abstract

Carbon dioxide (CO2) is one of the greenhouse gases that causes global warming with the highest concentration in the atmosphere. Mangrove forests can absorb CO2 three times higher than terrestrial forests and tropical rainforests. Moreover, mangrove forests can be a source of Indonesian income in the form of a blue economy, therefore an accurate method is needed to investigates mangrove carbon stock. Utilization of remote sensing data with the results of the above-ground carbon (AGC) detection model of mangrove forests based on multispectral imaging and vegetation index, can be a solution to get fast, cheap, and accurate information related to AGC estimation. This study aimed to investigates the best model for estimating the AGC of mangroves using Sentinel-2 imagery in Benoa Bay, Bali Province. The random forest (RF) method was used to classified the difference between mangrove and non-mangrove with the treatment of several parameters. Furthermore, a semi-empirical approach was used to assessed and map the AGC of mangroves. Allometric equations were used to calculated and produced AGC per species. Moreover, the model was built with linear regression equations for one variable x, and multiple regression equations for more than one x variable. Root Mean Square Error (RMSE) was used to assess the validation of the model results. The results of the mangrove forests area detected in the research location around 1134.92 ha, with an Overall Accuracy (OA) of 0.984 and a kappa coefficient of 0.961. This study highlights that the best model was the combination of IRECI and TRVI vegetation indices (RMSE: 11.09 Mg/ha) for a model based on red edge bands. Meanwhile, the best results from the model that does not use the red edge band were the combination of TRVI and DVI vegetation indices (RMSE: 13.63 Mg/ha). The use of red edge and NIR bands is highly recommended in building the AGC model of mangrove forests because they can increase the accuracy value. Thus, the results of this study are highly recommended in estimating the AGC of mangrove forests, because it has been proven to be able to increase the accuracy value of previous studies using optical images.

Abstract

Pemberian pakan komplit yang mengandung limbah pertanian kepada ternak akan meningkatkan utilitas bahan pakan terutama limbah pertanian. Pengawetan dengan cara silase bisa menjadi solusi saat pakan sulit ditemukan di musim kemarau. Silase yang ditambahkan additif akan meningkatkan kualitas fermentasinya. Penelitian ini bertujuan untuk mengkaji pengaruh yang ditimbulkan dari pakan silase pakan komplit dengan aditif fermented juice lactic acid bacteria (FJLB) yang berbeda terhadap imbangan energi dan nitrogen ternak domba lokal. Sebanyak 12 ternak domba lokal jantan dengan bobot badan awal 17,67 ± 1,7 kg (umur 12 bulan) disusun dalam rancangan acak lengkap.  Ransum terdiri dari jerami padi, bungkil kedelai, jagung, dedak padi, pollard dan mineral mix yang disilase menjadi pakan komplit selama 3 minggu. Perlakuan dalam penelitian ini antara lain yaitu T1= Silase tanpa aditif FJLB, T2= Silase dengan aditif FJLB dari Pennisetum purpureum, T3= Silase dengan aditif FJLB dari Pennisetum purpupoides, dengan 4 ulangan tiap perlakuan. Analisis data menggunakan uji ANNOVA. Hasil penelitian menunjukkan bahwa konsumsi energi dan energi tercerna pada T2 lebih rendah dibandingkan dengan control dan T3. Pemberian FJLB memberikan nilai kecernaan energi, energi termetabolisme, dan energi metana yang sama di semua perlakuan. Penambahan aditif FJLB menurunkan konsumsi protein kasar, namun aspek protein kasar tercerna, kecernaan protein kasar, protein kasar termetabolisme, dan allantoin menunjukkan nilai yang sama dengan kontrol. Dapat disimpulkan bahwa perbedaan penambahan aditif FJLB pada silase pakan komplit masih memberikan deposisi energi dan protein yang sama.

Abstract

Standar cemaran mikroba pada pangan olahan di Indonesia termuat dalam Peraturan Kepala Badan POM tahun 2009 No. HK.00.06.1.52.4011 tentang Penetapan Batas Maksimum Cemaran Mikroba dan Kimia Dalam Makanan dan Standar Nasional Indonesia (SNI) komoditas pangan. Dalam implementasinya, terdapat beberapa permasalahan dan kriteria yang tidak dapat dipenuhi karena terlalu ketat dan metode analisis yang tidak tersedia. Kajian ini bertujuan untuk membandingkan pemenuhan standar cemaran mikroba dalam pangan di Indonesia dan beberapa negara lain di dunia terhadap kaidah kriteria mikrobiologi pangan yang dikembangkan Codex serta mengkaji kriteria cemaran mikroba pada pangan prioritas dan memberikan rekomendasi kriteria cemaran mikroba. Pengkajian dilakukan dengan membandingkan dan menganalisis kriteria mikrobiologi Indonesia dengan 10 standar negara lain yaitu Australia dan Selandia Baru, Eropa, Filipina, Malaysia, Canada, Hong Kong, India, Jepang, Singapura dan Afrika Selatan berdasarkan Codex Principles for The Establishment and Application of Microbiological Criteria for Foods (CAC/GL 21-1997) yang sedang dalam proses revisi pada step 5/8. Studi kasus dilakukan pada beberapa jenis pangan prioritas berdasarkan permasalahan dan kriteria. Hasil kajian menunjukkan bahwa Australia dan Selandia Baru, Eropa, Canada dan Filipina telah mengikuti kriteria Codex, sementara Indonesia, Malaysia, Hong Kong, Jepang, Singapura dan Afrika Selatan tidak. Hasil kajian juga menunjukkan bahwa standar mikrobiologi air minum dalam kemasan, kopi instan dan pangan steril komersial perlu revisi. Untuk tujuan verifikasi proses produksi dan penerimaan lot, direkomendasikan untuk menetapkan satu batas maksimum ALT. Penetapan kriteria mikrobiologi kopi instan tidak relevan, kecuali OTA. Persyaratan bagi pangan proses steril komersial dapat dilakukan dengan pemenuhan kecukupan proses sterilisasi komersial atau uji inkubasi untuk menetapkan mikroba pembusuk.

Abstract

Kontaminasi mikroorganisme pada produk pangan kerap disebabkan oleh lingkungan pengolahan yang buruk serta proses pengolahan yang tidak higienis. Program Pemantauan Lingkungan (Environmental Monitoring Program) disingkat EMP, merupakan sebuah program yang dirancang untuk memverifikasi implementasi dan efektivitas program sanitasi serta pencegahan kontaminasi bahaya yang berasal dari lingkungan. Di, Indonesia, pedoman penyusunan EMP terdapat dalam Peraturan Kepala Badan Pengawas Obat dan Makanan Nomor HK.03.1.23.12.11.10720 tahun 2011 tentang Pedoman Cara Produksi Pangan Olahan yang baik untuk Formula Bayi dan Formula Lanjutan Berbentuk Bubuk. Sementara itu, pedoman EMP untuk jenis pangan lainnya belum tersedia. Penelitian ini bertujuan untuk memperoleh profil dari pedoman EMP, dengan melakukan kajian terhadap 17 pedoman EMP yang diterbitkan oleh Codex, berbagai negara serta asosiasi pangan internasional.  Selain itu penelitian ini bertujuan untuk memperoleh gambaran dokumen standar operasional EMP yang ada pada industri pengolahan pangan di Indonesia, dengan cara melakukan survei dengan menggunakan kuisioner. Hasil kajian pedoman EMP menunjukkan terdapat  11  komponen yang selalu ditemukan pada setiap pedoman yaitu  (1) penilaian risiko  (2) tujuan EMP (3) mikroorganisme target (4) lokasi pengambilan sampel (5) jenis sampel (6) titik dan jumlah sampel (7) tata cara pengambilan sampel (8) frekuensi pengambilan sampel (9) metode analisis sampel (10) manajemen dan analisis  data (11) tindakan perbaikan untuk hasil di luar batas. Pada penelitian ini 11 komponen tersebut dikategorikan sebagai komponen wajib penyusun pedoman maupun dokumen standar operasional EMP. Berdasarkan hasil survei terhadap industri pangan di Indonesia (n=37), sebanyak 64,.86% (24/37) responden menyatakan dokumen standar operasional EMP yang dimilikinya memuat 11 komponen wajib, serta sebesar 35,13% (13/37) responden menyatakan tidak memuat 11 komponen wajib tersebut.
