Youth have an essential role in the nation. Youth are considered pioneers of change; therefore, youth leadership and talents must be cultivated to the maximum. However, many challenges must be done by the government in developing it. Polytechnic of Land Transportation Bali is one of the universities that have the responsibility of developing leadership attitudes and youth talents. This research will examine the challenges and opportunities of leadership and talent development of Polytechnic of Land Transportation Bali cadet graduates. The research method used is descriptive qualitative research with literature study data collection techniques. The result of this study is that people in Indonesia have a traditional mindset to reduce the potential possessed by youth. Certain leadership and talents will be underestimated. However, it can be overcome by holding a leadership and talent program at the Polytechnic of Land Transportation Bali. The graduates were given character building before completing their education at the Polytechnic of Land Transportation Bali.

The agronomic characteristics of Robusta coffee plants are influenced by several factors, one of which is altitude. Robusta coffee can grow optimally at an altitude of 400-1,000 meters above sea level with a temperature of 21-24 °C. Pejawaran sub-district is known as a mountainous area with a height of 900-1600 m above sea level. This research was conducted in July to September 2019 in the coffee garden of Sarwodadi Village, Pejawaran District, Banjarnegara Regency. The selection of research sites was carried out by conducting a survey where 3 altitudes were selected that had a greater number of coffee plants. The research sites include 1,100 m asl, 1,200 m asl and 1,350 m asl, plant samples taken are 10% of the total plant population. Variables observed included chlorophyll a, chlorophyll b, stomata opening, stomata density, plant height, stem diameter, number of productive branches, number of bunches per plant and yield per plant. The results showed that the altitude of 1,100 m asl has chlorophyll content, the number of bunches per plant and yield per plant is better than the other heights of 20.95 mg / g, 8.64 mg / g, 113 and 6.64 kg. The chlorophyll content of a and b is positively related to the number of bunches. Stomatal openings are significantly positive for the number of productive branches. Plant height was negatively related to productive branches and number of bunches. Stem diameter is positively related to the number of bunches. The number of productive branches is positively related to the results.

827 Purwanto et. al. : Perubahan karakter biokimia dan fisiologi tanaman kacang hijau pada berbagai kondisi cekaman kekeringan Purwanto • B.R. Wijonarko • Tarjoko Perubahan karakter biokimia dan fisiologi tanaman kacang hijau pada berbagai kondisi cekaman kekeringan Changes in biochemical and physiology characters of mungbean in drought stress conditions Abstract. This study aims to examine the physiological and biochemical responses of mungbean plants to drought stress. The research was conducted at the Screen House Exfarm, Faculty of Agriculture, Jenderal Soedirman University, Purwokerto, from March to October 2018. Experiment used Randomized BlockDesign with factorial treatment. The first factor was the level of soil moisture, consisted of level of 100% field capacity as control, 75% field capacity, and 50% field capacity. The second factor was the superior varieties of mungbeans, consisted of Vima 2, Vima 3, and Kutilang varieties. The results showed that drought stress up to 50 percent of field capacity had shown a decrease in the character of leaf area and dry weight of plants, but it had not affected the prolin content of mungbean plants.

The aims of this research was to study the net assimilation rate, growth and yield of rice with the application of PGPR in different rate of nitrogen fertilizer. The experimental was conducted in experimental farm of Agriculture Faculty of UNSOED Purwokerto. The research was arranged in Randomized Block Design with three replications. The first factor is PGPR consortium, and the second factor is dosage of nitrogen fertilizer. The observed variables were plant height, number of tillers, plant biomass, leaf greenness, plant biomass, net assimilation rate, relative growth rate and yield. Data were analyzed using ANOVA followed with DMRT test for mean comparison between group. The results showed that PGPR consortium inoculation and nitrogen fertilization have effect on root growth, leaf greenness, and plant biomass. The PGPR consortium R08 isolate + R11 isolate and nitrogen fertilizer at dose of 1.36 g plant−1 gave highest net assimilation rate of 5.87 g dm−2 week−1. The highest grain yield was achieved at nitrogen fertilizer dose of 2.72 g plant−1 at 36.17 g per hill.

Pada tanaman radish pupuk KNO3 berfungsi untuk membantu meningkatkan proses pembentukan umbi dan mulsa berfungsi untuk menghindari kehilangan air melalui penguapan dan menekan pertumbuhan gulma. Penelitian ini bertujuan untuk mengetahui (1) pengaruh pemberian beberapa taraf dosis pupuk KNO3 yang menghasilkan respons terbaik tanaman radish, (2) mengetahui respons tanaman radish akibat aplikasi mulsa, (3) mengetahui respons tanaman radish akibat pemupukan KNO3 berbagai dosis yang diaplikasikan pada lahan dengan mulsa dan tanpa mulsa. Penelitian ini dilaksanakan di Laboraturium Lapang Terpadu Fakultas Pertanian Universitas Lampung, Kota Bandar Lampung pada bulan Mei hingga Juni 2012. Rancangan lingkungan yang digunakan adalah Rancangan Kelompok Teracak Sempurna dengan tiga ulangan. Rancangan perlakuan disusun secara faktorial (5 x 2). Faktor pertama adalah dosis pupuk KNO3 (K) yang terdiri dari 5 taraf, yaitu 0 kg ha-1 (K0); 75 kg ha-1 (K1); 150 kg ha-1 (K2); 225 kg ha-1 (K3); dan 300 kg ha-1 (K4). Faktor kedua adalah aplikasi mulsa (M) yang terdiri dari dua taraf yaitu tanpa pemberian mulsa (M0), dan mulsa plastik hitam perak (M1). Hasil penelitian menunjukkan bahwa dosis pupuk KNO3 sampai dosis 300 kg ha-1 belum ada yang menghasilkan respons terbaik tanaman radish. Aplikasi tanpa mulsa memiliki respons/hasil yang lebih baik dibandingkan dengan menggunakan mulsa untuk tanaman radish. Pada dosis KNO3 yang sama, tanpa menggunakan mulsa didapatkan produksi tanaman per petak yang lebih tinggi dari pada menggunakan mulsa.
