The paper presented observes the study results from a period of six years in terms of losses of mineral nitrogen and available forms of phosphorus and potassium in the cultivation of wheat and maize on sloping terrains (on calcic chernozem soil type) under the influence of water erosion processes. The impacts of four different types of technology (conventional technology performed along the slope; conventional technology applied across the slope; surface mulching; and minimum tillage with vertical mulching) on nutrient losses were tested. On average, the annual losses of mineral nitrogen, available forms of phosphorus and potassium in wheat production along the slope utilizing conventional technology were 6.0 kg·ha−1y−1, 1.6 kg·ha−1y−1, 5.9 kg·ha−1y−1, and 11.3 kg·ha−1y−1, 2.1 kg kg·ha−1y−1, 10.8 kg kg·ha−1y−1 in maize production. The lowest losses in these elements occurred with minimal employment of tillage system, as they reached values of 2.3 kg·ha−1y−1; 0.6 kg·ha−1y−1, 2.0 kg·ha−1y−1, respectively, in wheat production, and 1.7 kg·ha−1y−1, 0.3 kg·ha−1y−1, 1. kg·ha−1y−1, respectively, in maize production.","PeriodicalId":43089,"journal":{"name":"Acta Technologica Agriculturae","volume":"25 1","pages":"113 - 121"},"PeriodicalIF":1.4,"publicationDate":"2022-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43258630","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Digital side mirror technology is one of the latest topics in the field of advanced driver assistance systems which is developing rapidly. This study evaluates the applicability of digital side mirror technology in the car interior, based on drivers’ feedbacks. The research was conducted in the form of a questionnaire to determine the drivers’ reactions and affinity to new technology, based on personal experience gained in simulated traffic and also in real traffic situations. The data obtained from this research were then subjected to Pearson’s Chi-squared test to evaluate the drivers’ dependence and comfort with the digital side mirror technology. Subsequently, mainly statistically significant dependencies in the preferences of individual drivers were sought due to their personal and anthropometric parameters. The results published in this study can be used mainly to understand the process by which drivers form an opinion on new technology which may be key to their further stance on the technology and may also affect the commercial success of digital mirror technology during their involvement in serial production.","PeriodicalId":43089,"journal":{"name":"Acta Technologica Agriculturae","volume":"49 9","pages":"122 - 130"},"PeriodicalIF":1.4,"publicationDate":"2022-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41276955","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Untuk meningkatkan potensi daerah tersebut, maka penelitian eksplorasi pengolahan biji kopi yang dihasilkan menjadi penting untuk dilakukan. Salah satu proses pengolahan kopi yang penting yaitu proses penyangraian. Penyangraian merupakan proses pembentukan rasa dan aroma pada biji kopi. Tujuan penelitian ini untuk mengetahui perubahan kandungan kafein dan sifat fisik kopi robusta yang dihasilkan oleh petani lokal setempat. Terdapat tiga variasi suhu dan waktu penyangraian yang digunakan dalam penelitaian ini. Untuk pengamatan suhu penyangraian dilakukan pada suhu 190oC, 200oC, 210oC dan durasi lama penyangraian digunakan pada 10, 15, dan 20 menit. Hasil penelitian menunjukkan kombinasi temperatur 190oC dan lama penyangraian 10 menit memiliki kadar kafein terendah yaitu sebesar 3,18%. Selain itu, diketahui berdasarkan uji Duncan faktor lama penyangraian memiliki pengaruh sangat nyata terhadap jumlah kadar air dan densitas curah pada biji kopi. Sedangkan melalui pengamatan uji fisik diketahui bahwa semakin besar suhu dan semakin lama durasi penyangraian dapat mengakibatkan biji kehilangan kadar air juga semakin besar maka massa pada bijipun berkurang","PeriodicalId":43089,"journal":{"name":"Acta Technologica Agriculturae","volume":"69 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2022-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85533863","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
