Ikan asin adalah metode untuk pengawetan makanan menggunakan kombinasi penggaraman dan pengeringan matahari. Di kalangan masyarakat, pembuatan ikan asin banyak menggunakan bahan kimia berbahaya seperti formalin. Penambahan bahan berbahaya mempengaruhi kualitas terutama keamanan. Makanan yang aman didefinisikan sebagai makanan yang terbebas dari cemaran biologi, kimia, mikrobiologi, yang dapat mempengaruhi kesehatan. Karbon aktif diduga bersifat polar yang mampu mengadsorpsi formalin. Tujuan penelitian ini adalah untuk mengetahui pengaruh pemberian karbon aktif dalam mengurangi cemaran formalin pada “jambal roti”. Rancangan percobaan yang digunakan untuk percobaan yaitu Rancangan Acak Lengkap (RAL) 2 faktorial, dengan faktor pertama yaitu konsentrasi karbon aktif 0, 3, dan 6% serta perlakuan kedua yaitu lama perebusan selama 5, 10, dan 15 menit. Penelitian ini dimulai dari pembuatan “jambal roti” dengan penambahan formalin dan perebusan dengan karbon aktif kemudian dianalisis uji kadar formalin, NaCl, protein, dan air. Hasil penelitian menunjukkan bahwa konsentrasi karbon aktif dan lama perebusan memberikan pengaruh yang signifikan pada kualitas jambal roti. Semakin tinggi konsentrasi karbon aktif dan lama perebusan maka semakin berkurangnya kadar formalin pada jambal roti. Hasil terbaik penelitian ini adalah karbon aktif 6% dan lama perebusan 15 menit. Menghasilkan formalin 3.21 ppm, NaCl 9.40%, protein 42.00%, dan air 30.02%. Kata kunci: Karbon Aktif, Formalin, Jambal Roti, Lama Perebusan. ABSTRACT                 Salted fish was a method for food preservation using combination of salting and sun drying. Among the people, the manufacture of salted fish use hazardous chemical material such as formaldehyde. The addition of hazardous substances affects the quality especially the safety. Safe food define as food that free from biological, chemical, microbiological contaminants that can affect health. Active carbon suspected to be polar which able to adsorb formaldehyde. The purpose of this research was to determine the influence of active carbon in reducing formaldehyde in salted fish “jambal roti”. The research used completely randomized design (CRD) with 2 factors, the first factor was the concentration of active carbon 0, 3, and 6% and the second was the boiling time (for 5, 10, and 15 min). This research was started from making “jambal roti” with the addition of formaldehyde and boiling with active carbon then analyzed for formaldehyde content, NaCl, protein, and moisture. The result showed that the concentration of active carbon and boiling time had a significant effect in quality salted fish “jambal roti”. The higher the concentration of active carbon and boiling time the more formaldehyde in “jambal roti” were removed. The best results of the research was 6% active carbon and 15 min of boiling time. Resulting 3.21 ppm of formaldehyde, 9.40% of NaCl, 42.00% of protein, and 30.02% of moisture. Keywords: Active Carbon, Formaldehyde, Jambal Roti, Boiling Time

Providing the population with quality and safe food, in particular meat, is one of the main tasks facing agricultural producers. An important role is assigned to pig breeding, since pigs are characterized by high fertility and precocity [1, p. 25]. The aim of the work was to assess the productive qualities ofpure-bred and hybrid sows when crossing with purebred boars. The studies were conducted in the pig farm "Slavyanka". Productive qualities of sows were assessed by multiple pregnancy, large young, milk production, weight of the nest at birth and on the 30th day at weaning, as well as by the level ofpigs’ safety. These studies showed that hybrid sows outperformed purebred sows (13.70±0.40) in multiple pregnancy (14.6±0.04 piglets). The milk content of purebred sows was lower by 4.73 kg or 10.50 % than that of two-breed hybrids. The mass ofpiglets’ nest at birth in crossbred sows when crossing with Pietrain boar outperformed the mass ofpurebred sows’ nests by 3.4 kg, or 17,60%. The output of business piglets was almost the same and amounted to 13.01 heads have hybrid sows and 12.05 heads purebred. Safety of piglets was, respectively, 90% and 87%. Two-breed hybrids significantly outperformed purebred sows by nest weight at weaning by 14.3%, the average weight of one pig by 9.42%. Thus, studies have shown that crossbred sows crossed by terminal boar of Pietren breed, outperformed purebred ones on many para-metres.

Due to extreme water scarcity Jordan is integrating reclaimed water resources in the national water management system. This paper describes the recent framework conditions for reclaimed water use in agriculture in Jordan, with a focus on the central and southern Jordan Valley. The possible impacts of lower quality irrigation water on soil, groundwater, crops and human health are considered while appropriate guidelines and monitoring proposals are being developed. Testing of the guidelines and implementation of the monitoring systems have started with the final purpose of integrating them into the Jordanian standard and legal system and thus ensuring safe food for consumers and protection of the environment.

Background and Objectives: In this work, yellow and green varieties of Cucumis melo fruits belonging to different cultivars were studied. In detail, three Sicilian cultivars of winter melons tutelated by TAP (Traditional agro-alimentary products) labels were considered, whereas asun protected the Calabrian winter melon was studied too. With the aim to compare the selective uptakes of inorganic elements among winter and summer fruits, the “PGI Melone Mantovano” was investigated. The purpose of this work was to apply the obtained results i) to guarantee the quality and healthiness of fruits, ii) to producers defend, iii) to help the customers in safe food purchase. Method: All samples were analyzed by ICP-MS and the obtained results, subsequently, were subjected to Cluster analysis (CA), Principal component analysis (PCA) and Canonical discriminant analysis (CDA). Results: CA results were generally in agreement with samples origin, whereas the PCA elaboration has confirmed the presence of a strong relation between fruit origins and trace element contents. In particular, two principal components justified the 57.32% of the total variance (PC1= 40.95%, PC2= 16.37%). Finally, the CDA approach has provided several functions with high discrimination power, confirmed by the correct classification of all samples (100%). Conclusions: CA, PCA and CDA could represent an integrated to label to discriminate the origin of agri-food products and, thus, protect and guarantee their healthiness.

There is a general need to facilitate citizens’ understanding of the global sustainability problem with the dual purpose of raising their awareness of the seriousness of the problem and helping them get closer to understanding the complexity of the solutions. Here, the design and application of the participatory simulation game Global Sustainability Crossroads is described, based on a global state-of-the-art energy–economy–environment model, which creates a virtual scenario where the participants are confronted with the design of climate mitigation strategies as well as the social, economic, and environmental consequences of decisions. The novelty of the game rests on the global scope and the representation of the drivers of anthropogenic emissions within the MEDEAS-World model, combined with a participatory simulation group dynamic flexible enough to be adapted to a diversity of contexts and participants. The performance of 13 game workshops with ~420 players has shown it has a significant pedagogical potential: the game is able to generate discussions on crucial topics which are usually outside the public realm such as the relationship between economic growth and sustainability, the role of technology, how human desires are limited by biophysical constraints or the possibility of climate tipping points.

Grounded in a design-based research approach, the aim of this article is to determine whether scientific evaluations help to (a) identify and fix problems in educational interventions and (b) eventually foster a more effective and positive evaluated intervention. Therefore, data from a longer-term evaluation of short digital simulation games about the European Parliament for civic education in schools were used. The data included three cycles of interventions with pre- and post-evaluations starting with the first prototype in 2015/2016 (n = 209), the second cycle in 2017/18 (n = 97), and the last one in 2019/20 (n = 222). After each evaluation, major problems and critiques regarding the simulation game were discussed with the developers, and changes were implemented in the game design. The four most important problems, the processes by which they were improved and the reactions of the participants in the following evaluations are pointed out in the article. A comparison of the last and first evaluation cycle showed an overall improvement of the simulation game regarding its effectiveness in transferring EU knowledge and the participants’ general satisfaction with the simulation game. This study underlines the value of the design-based research approach for developing educational interventions and can be useful for further work on civic education measures and the implementation of digital simulation games.
