Abstract

This study discusses the understanding of public policy efforts toward improving the quality of democracy in the digital era. We chose the design of this study as a qualitative design by relying on secondary data in the form of published journals and books, and websites that actively discuss public policy issues in the technology era as part of efforts to increase democracy. The data we collect from some sources will then be analyzed under a phenomenological approach, attempting to understand a question from several existing data. The process involves a data coding system, data interpretation, and carefully evaluating the data to understand relevant to answering the problem. Based on the data we have discussed, we conclude that the understanding of public services towards improving the quality of democracy in the digital era is a public service arranged in such a way by relying on data or electronic government, where every agency has digital services. This is done to transform government services using technology ready to serve its citizens without boundaries and time

Abstract

Since the world's covid outbreak, each country has issued a response policy, including prevention and treatment. One of the preventions carried out by Indonesian youth is to carry out special tests with much attached policies and tell the stories of various parties. The authors believe that today's television is full of practices between health conflicts and conflicts of interest of the parties. To prove these assumptions and allegations, we conducted an instant data search on the application of health journals and also social crises in Indonesia, and we found that the data was then taken by a phenomenological approach and then analyzed with data coding, in-depth analysis, rigorous evaluation and also concluding passing through the data. Various high interpretations to obtain valid and accurate data in answering the problems of this study. Based on the available data, then the discussion we found that the understanding of the physical test, which is a government policy has found that the issue of pollution is a problem where we found several interests and conflicts that occurred so that until now it remains an unsolved problem. Hopefully, this data will be valuable input for efforts to improve and provide the first service to understand the meaning of the PCR test in Indonesia.

Microgreen merupakan tanaman hijau yang dipanen pada usia muda yang dihasilkan dari benih sayuran dari berbagai jenis sayuran yang biasa dikonsumsi oleh masyarakat umum. Pemeliharaan tanaman microgreen yang tidak membutuhkan lahan luas menjadi salah satu solusi teknik budidaya tanaman modern. Tanaman lobak memiliki kandungan nutrisi yang lebih tinggi jika dikonsumsi dalam bentuk microgreen. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh kombinasi perlakuan pre-sowing dengan fertigation regime dan menentukan kombinasi perlakuan yang menghasilkan produktivitas microgreen terbaik. Rancangan percobaan yang digunakan dalam penelitian ini adalah Rancangan Acak Kelompok (RAK) dengan dua faktor yaitu perlakuan pre-sowing dan fertigation regime dengan 3 kali ulangan. Hasil dari penelitian yang telah dilakukan yaitu kombinasi perlakuan pre-sowing dan fertigation regime berpengaruh nyata terhadap berat basah dan berat kering microgreen, dan tidak berpengaruh nyata terhadap tinggi tanaman dan kandungan klorofil tanaman microgreen lobak. Kombinasi perlakuan pre-sowing direndam dengan fertigasi setiap hari memiliki rata-rata tertinggi pada setiap variabel yang diamati yaitu tinggi tanaman 9,49 cm, jumlah kandungan klorofil 45,99 SPAD, berat basah 108,70 gram, dan berat kering tanaman 9,70 gram. Berdasarkan hasil penelitian, kombinasi perlakuan pre-sowing direndam dengan pemberian fertigasi setiap hari pada microgreen lobak merupakan perlakuan yang menghasilkan produktivitas microgreen terbaik. ABSTRACT Microgreen are green plants that are harvested at a young age which are produced from vegetable seeds from various types of vegetables commonly consumed by the general public. Maintenance of microgreen plants that do not require large areas of land is one of the solutions for modern plant cultivation techniques. Radish plants have a higher nutritional content when consumed in the form of microgreen. The purpose of this study was to determine the effect of the pre-sowing treatment combination with the fertigation regime and to determine the treatment combination that produces the best microgreen productivity. The experimental design used in this study was a randomized block design (RBD) with two factors, namely the pre-sowing treatment and the fertigation regime with 3 replications. The results of the research that has been done are that the combination of pre-sowing treatment and fertigation regime has a significant effect on fresh weight and dry weight of microgreen, and has no significant effect on plant height and chlorophyll content of radish microgreen plants. The combination of pre-sowing treatment soaked with fertigation every day had the highest average for each variable observed, namely plant height 9.49 cm, total chlorophyll content 45.99 SPAD, fresh weight 108.70 grams, and plant dry weight 9.70 grams. Based on the results of the study, the combination of pre-sowing soaked treatment with daily fertigation of radish microgreens was the treatment that produced the best microgreen productivity.

Abstract

Abstrak Salah satu satuan ukuran getaran, gelombang listrik, atau getaran yang dihasilkan per detik ialah frekuensi. Elemen mesin yang memindahkan tenaga dari satu poros ke poros lainnya melalui sabuk yang disebut katrol dapat menimbulkan getaran. Pulley meneruskan gerak dan mengubah arah putaran searah dengan gaya yang diberikan. Tujuan dari penelitian ini yaitu modifikasi rasio pulley untuk memperoleh frekuensi yang lebih rendah dan untuk memperoleh nilai frekuensi pada maing-masing kombinasi diameter pulley pada alat meja getar. Sebelum dimodifikasi alat ini menggunakan 2 pulley dan menghasilkan getaran yang besar sehingga membuat produk pertanian memar di bagian kulit, lalu dimodifikasi dengan menambahkan 2 pulley untuk menurunkan nilai frekuensinya. Parameter yang diamati yaitu memperhitungkan kecepatan keliling pada masing-masing pulley, memperhitungkan jumlah putaran belt, pengaturan kecepatan dari pulley ke pulley. Hasil penelitian menunjukan bahwa diperoleh frekuensi yang lebih rendah dengan menggunakan 4 kombinasi diameter pulley, dimana pulley A berukuran 5cm dengan putaran 1496 rpm, pulley B berukuran 20cm dengan putaran 374 rpm, pulley C berukuran 7cm dengan putaran 374 rpm, pulley D berukuran 30cm dengan putaran 87,27 rpm. Nilai frekuensi yang dihasilkan oleh 4 pulley yaitu 0,105 Hz lebih rendah dibandingkan dengan 2 pulley yaitu 3 Hz, pengujian ini dilakukan dengan box kayu yang diisi produk pertanian yaitu kentang bibit yang dijalankan selama 120 menit. Hasilnya, kentang bibit hanya mengalami pergeseran ke kanan dan kiri dan ada pula yang terbalik tetapi tidak mengalami kerusakan fisik. Abstract Frequency is the number of vibrations that occur in one second or the number of electrical waves or vibrations produced every second. Vibrations can be produced by machine elements whose function is to transmit power from a shaft to another using a belt called a pulley. The pulley works in the direction of the applied force, sending motion and changing the direction of rotation. The aim of this research is to modify the pulley ratio to obtain a lower frequency and to obtain frequency values ??for each combination of pulley diameters on the vibrating table tool. Before being modified, this tool used 2 pulleys and produced large vibrations that caused agricultural products to bruise the skin. Then it was modified by adding 2 pulleys to lower the frequency value. The parameters observed are calculating the circumferential speed on each pulley, calculating the number of belt revolutions, setting the speed from pulley to pulley. The research results show that a lower frequency is obtained by using 4 combinations of pulley diameters, where pulley A measures 5cm with a rotation of 1496 rpm, pulley B measures 20cm with a rotation of 374 rpm, pulley C measures 7cm with a rotation of 374 rpm, pulley D measures 30cm with a rotation 87.27 rpm. The frequency value produced by 4 pulleys, namely 0.105 Hz, is lower than with 2 pulleys, namely 3 Hz. This test was carried out with a wooden box filled with agricultural products, namely seed potatoes, which was run for 120 minutes. As a result, the seed potatoes only experienced shifts to the right and left and some were tipped over but did not experience physical damage.
