<p>ABSTRACT</p><p>Mandarins (Citrus  reticulata)  is  one  of  the  important  fruit  commodity  in Indonesia. The problems  that  often  arise  in  the  development  is  the availability  of  healthy  seedlings  and  in  large numbers. The purpose of this research was to determine the effect of Benzyl Amino Purines (BAP) onthe success of budding and bud  growth  on the plant  mandarins  Borneo  Prima and  Garut  Dataran Rendah.  This  research  was  conducted  at  the  Pasir Kuda  Experimental  Farm,  Ciomas,  Bogor  in January  to  May  2013.  This experiment  was arranged in  a randomized complete block design with two factors of the scions varieties (Borneo Prima and Garut Dataran Rendah) and the concentration of  BAP  (0, 5, 10, and 15 ppm),  repeated 3  times  so there were 24  experimental units. The research data was analyzed statistically using F test at 5% and continued with DMRT test at 5%. The results showed that the application  of BAP  at  low concentration on  the scions  of the  two  varieties do  not give significantly different results in the variable of success of budding and growth of plant shoots.</p><p>Keywords: bud, cytokinin, nutrition, rootstock, scion</p><p> </p><p>ABSTRAK</p><p>Jeruk  keprok  (Citrus  reticulata)  merupakan  salah  satu  komoditas  buah yang  penting  di Indonesia. Permasalahan yang sering muncul dalam pengembangan jeruk keprok adalah ketersediaan bibit  yang  sehat  dalam jumlah  banyak.  Tujuan  penelitian  ini  adalah  untuk  mengetahui pengaruh pemberian  Benzil  amino  purin  (BAP)  terhadap  keberhasilan okulasi  dan  pertumbuhan  tunas  pada tanaman  jeruk  keprok  Borneo  Prima dan  Garut  Dataran  Rendah.  Penelitian  ini  dilaksanakan  di Kebun Percobaan Pasir  Kuda,  Ciomas,  Bogor  pada  bulan  Januari  sampai  bulan  Mei  tahun 2013. Penelitian disusun dalam rancangan kelompok lengkap teracak (RKLT) faktorial dengan dua faktor yakni varietas batang atas (Borneo Prima dan Garut Dataran Rendah) dan konsentrasi BAP (0, 5, 10, 15 ppm),  diulang 3 kali sehingga terdapat 24 unit percobaan. Data hasil percobaan dianalisis secara statistika dengan uji F pada taraf nyata 5% dan dilanjutkan dengan uji lanjutan DMRT pada taraf nyata  5%  untuk  nilai  yang  berbeda  nyata.  Hasil penelitian  menunjukkan  bahwa  pemberian  BAP dengan konsentrasi rendah pada dua varietas batang atas jeruk keprok  tidak memberikan hasil yang berbeda nyata pada peubah keberhasilan okulasi dan pertumbuhan tunas tanaman.</p><p>Kata kunci: batang atas, batang bawah, nutrisi, sitokinin, tunas</p>

To reduce fluctuations in the supply and price of shallots, the release of shallot varieties is necessary because shallots are an important vegetable crop in Indonesia and as an effort to increase the productivity of shallots in Indonesia. The availability of high-yielding and disease-resistant shallot varieties will ensure long-term output. This research aims to test the productivity of the newly released variety, SS Sakato, in three different locations in Indonesia. This variety was developed by the Center for Tropical Horticultural Studies in a participatory plant breeding scheme with farmers from 2014 to 2017. The research was conducted in Solok, Kuningan, and Bogor from September 2020 to July 2021. The results showed that the SS Sakato variety grew well in all locations. According to the variety description, SS Sakato had the potential for tuber yields of 17.52-28 tons/ha, whereas productivity in the three research locations was 27.62-29.44 tons/ha (Bogor), 26.66-29.42 tons/ha (Solok), and 18.20-21.33 tons/ha (Kuningan). This indicates that the SS Sakato variety is adaptable and can be used as a national variety in Indonesia to increase shallot production and farmers' incomes.

This study to analyze the effect of workload on turnover intention, workload on job satisfaction, competence on job satisfaction, competence on turnover intention, training on job satisfaction and job satisfaction on turnover intention. Data was collected through interviews using a questionnaire. Respondents in MNC Media division news gathering employees numbered 202 people. The analytical method used in this study is Structural Equation Modeling (SEM) which is processed using AMOS 22. The results of this study indicate that workloads have a significant effect on decreasing job satisfaction. Besides that the workload increases the desire to get out of work or company. Training has the effect of increasing job satisfaction from employees towards their employment. Employee competencies are known to have a positive influence on satisfaction but negative on turnover intention. While job satisfaction has a positive influence on turnover intention, the lower the job satisfaction, the higher the desire to get out.

Perakitan varietas melon unggul baru memerlukan materi genetik yang beragam. Ekspresi keragaman genetik memerlukan lingkungan yang mendukung, salah satunya adalah ketersediaan air bagi tanaman. Penelitian ini bertujuan: (1) mempelajari pengaruh varietas (V), perlakuan irigasi (I), interaksi VxI terhadap karakter melon, (2) mengestimasi komponen ragam dan heritabilitas arti luas karakter melon, (3) mengestimasi produktivitas air dan penggunaan air tiap tanaman melon. Percobaan dilakukan di rumah kaca Kebun Percobaan Cikabayan, Departemen Agronomi dan Hortikultura, Fakultas Pertanian IPB, Darmaga, Bogor, pada bulan September-November 2017 menggunakan rancangan tersarang dengan dua faktor dan lima ulangan. Lima varietas melon (‘Honey Dew’, ‘Honey Blonde’, ‘Brilliant’, ‘Athena’, dan ‘Serenade’) ditempatkan secara acak pada tiap ulangan di dalam tiap taraf perlakuan irigasi (784 L, 1,127 L, dan 1,407 L). Varietas berpengaruh nyata terhadap karakter diameter batang, panjang daun, lebar daun, umur berbunga jantan, umur berbunga hermafrodit, panjang buah dan padatan terlarut total. Perlakuan irigasi tidak berpengaruh nyata terhadap semua karakter tanaman, namun interaksi VxI berpengaruh nyata pada karakter umur panen. Karakter padatan terlarut total dan panjang daun memiliki nilai heritabilitas arti luas >50%. Produktivitas air irigasi adalah 153.7 kg ha-1 mm-1 dan total penggunaan air untuk tiap tanaman pada perlakuan irigasi P1, P2, dan P3 masing-masing adalah 38.58 L, 50.78 L, dan 73.19 L.
