Abstract The application of technology for water erosion control plays an essential role in development of sustainable agricultural systems. 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.

Abstract The automotive industry is experiencing an era of technological innovations from conventional passenger cars, trucks to agricultural machinery. 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.

Abstract When using complex spatial patterns for transportation, the straight screw conveyors have a series of obvious disadvantages. This paper presents a design of a flexible screw sectional working body that allows increasing the functional and operational characteristics of screw conveyors used in the transportation of bulk agricultural materials. A mathematical model of the dynamic system of a flexible screw conveyor has been established, and dynamic starting torques have been calculated at the rated load of loaded screw, and when the system is braking. Analysis of the results obtained shows that, with significant damping coefficients, the start-up transition process occurs smoothly, and the load reaches its rated value without torque and speed fluctuations. It has been established that fast braking significantly increases the dynamic loads that may exceed the maximum critical torque of the electric motor (by 50–70% on average) and the rated load torque (by 2.5–3 times).

Abstract The paper presented deals with the accuracy of three selected devices based on acceleration measurement: accelerometer – XL meter, the global position measurement device by VBox and the constructed 5th wheel, which allows a very accurate measurement of distance along with speed and acceleration of the vehicle. The accuracy of recordings was tested during various driving conditions when all the three measuring devices were attached to the vehicle. Measurements showed that GPS-based measuring devices level off and even surpass accelerometers when used in locations with a good view of the sky. The 5th wheel provided the most representative results, as the difference between average and real standard deviations of the measured distance were 0.78%, 1.38%, 3.48% for the 5th wheel, VBox GPS and XL meter, respectively. The accuracy of the 5th wheel and VBox can be considered very high when taking into account the fact that dynamic actions were monitored. The paper purpose is to point out the significance of measuring device selection in assessing the distance travelled by the vehicle.

Sampah organik merupakan sampah yang mudah mengalami pembusukan (dekomposisi). Masalah sampah kerap kali menjadi bahan perbincangan di semua kalangan, namun sampai saat ini belum ada langkah kerja yang bisa diambil. Hal tersebut di butuhkan kerjasama yang nyata antara masyarakat dan pemerintah untuk mewujudkan kebersihan dan keindahan lingkungan yang di inginkan bersama. Tujuan dari penelitian ini adalah melakukan rancang bangun mesin pencacah sampah, melakukan uji kinerja serta menghitung analisa ekonomi. Metode penelitian diawali identifikasi masalah dan penyempurnaan rancangan mesin pencacah sampah. Mesin ini memiliki panjang 110.5 cm, lebar 41 cm, dan tinggi 109.5 cm. Mesin yang dipakai menggunakan engine diesel sebesar 6 HP dengan kecepatan putar 2600 Rpm. Rangka alat ini menggunakan besi siku berukuran 50 x 50 mm.

Setiap tahun Kota Payakumbuh mengalami peningkatan penggunaan air bersih, hal ini dapat dilihat dari terjadinya peningkatan jumlah pelanggan PDAM disetiap tahun. Terjadi peningkatan sebesar 9.335 pelanggan selama Sembilan tahun, atau rata-rata meningkat seribu pelanggan setiap tahunnya. Seiring dengan bertambahnya jumlah masyarakat pengguna air bersih maka hal ini dikhawatirkan dapat mengakibatkan terjadinya potensi penurunan debit air bersih. Pada bagian lain pertumbuhan jumlah penduduk setiap tahunnya juga menyebabkan penggunaan lahan terbangun yang terus meningkat. Untuk mengantisipasi penurunan potensi air bersih ini maka dilakukan analisis daya dukung lahan dan daya tampung air Kota Payakumbuh. Penelitian ini menggunakanan metode Analisis Driver, Pressure, Impact dan Respons serta Study literatur.Hasil dari analisis, perlunya peningkatan luas dan kualitas daerah tangkapan air,Meningkatkan tutupan vegetasi pada lahan-lahan terbuka, pengembangan tata kelola lahan basah,Peningkatan pengawasan dan pemantauan tutupan lahan.

Kabupaten Jember memiliki beberapa wilayah yang berpotensi dalam pengembangan kopi, salah satunya di Desa Banjarsengon Kecamatan Patrang yang memiliki luas lahan 65 hektar. 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

Untuk menghindari kesalahan dalam menetapkan penerima Beasiswa Program Indonesia Pintar (PIP) diperlukan sebuah metode yang cocok untuk memutuskan siswa yang berhak menerima beasiswa PIP tersebut. Tujuan penelitian adalah menentukan siswa penerima beasiswa PIP menggunakan metode Analytic Network Process (ANP) yang diimplementasikan menggunakan sistem penunjang keputusan open source (superdecission). Data diperoleh secara langsung pada SMPN 1 Batang Anai melalui tanya jawab dengan bagian keuangan menggunakan kuisioner. Kriteria yang menjadi pertimbangan dalam pengambilan keputusan adalah 1) pekerjaan orang tua, 2) pendapatan orang tua,3) rata-rata nilai raport, dan 4)jumlah tanggungan. Dengan menentukan nilai perbandingan masing-masing kriteria, menetapkan nilai rata-rata, dan menentukan bobot akhir dengan perhitungan menggunakan superdecission, maka dapat ditentukan 5 orang siswa penerima beasiswa PIP secara berurut adalah 1) OR1 (35%), 2) OR3 (35%), 3) OR5 (35%), 4) OR2 (27%), dan 5) OR6 (27%).
