Judul: Penerapan Standar Operasional Produksi Untuk Meningkatkan Pertumbuhan, Produksi Dan Kualitas Pisang Tanduk (Musa Sp., Aab Group)
Abstrak: The objective of this research was to determinate effect using cultivation technique in growth, yield, and quality of ‘Pisang Tanduk’. This research was conducted on May 2010 until October 2011 in Kopo, Cisarua Bogor. Quality observation was conducted at Postharvest Laboratory Departement of Agronomy and Horticulture, FAPERTA IPB. Treatment tested were traditional cultivation technique, production operational standard of banana monoculture and production operational standard of banana intercropping. Banana production operational standards that used were a modification of the production operational standard of ‘Rajabulu’ Banana (PKBT, 2007). The results showed that cultivation techniques is significantly affected in growth and production of banana. Implementation production operational standard of banana can increased optimum growing. An examination of bunch weight, hands weight and fruit weight found that they generally greatest in implementation production operational standard of banana. Cultivation techniques also significantly affected on the fruit length and diameter of banana. Chemical quality is not significantly affected by cultivation techniques except for total soluble solids. Cultivation vegetable within banana planting is one alternative to increase revenue to farmer with R/C ratio 2.00. Vegetable planting did not affect banana growth and yield.

Judul: Postharvest Character Study of Tanduk Banana (Musa paradisiaca, Group AAB) for Optimization of Heat Unit as a Measurable Harvest Criterion
Abstrak: Pisang, selain menjadi bahan pangan, memiliki arti yang penting bagi Indonesia karena memiliki nilai budaya dan sosio-ekonomi. Pisang memiliki keunggulan sebagai komoditas yang relatif mudah dan murah untuk dibudidayakan. Buah pisang mudah diolah dan dikonsumsi oleh rumah tangga. Penelitian ini dilaksanakan untuk menilai ketepatan umur panen berdasarkan hari setelah antesis (HSA) yang dikonversi ke satuan panas sebagai kriteria panen terukur untuk pisang Tanduk. Percobaan dilaksanakan di Kebun Percobaan Sukamantri, Bogor, Jawa Barat pada ketinggian 550 meter di atas permukaan laut sejak bulan Januari 2020 hingga Mei 2020. Pengujian kualitas pascapanen pisang Tanduk dilaksanakan di Laboratorium Pascapanen, Departemen Agronomi dan Hortikultura, Fakultas Pertanian, Institut Pertanian Bogor hingga bulan Agustus 2020. Penelitian ini dilakukan dengan rancangan acak lengkap dengan 5 ulangan untuk menguji 5 umur panen: 50, 55, 60, 65, dan 70 HSA. Umur panen tersebut setara dengan akumulasi satuan panas: 965, 1067, 1134, 1201, dan 1297 ˚C hari. Hasil percobaan menunjukkan bahwa perbedaan umur panen tidak mempengaruhi umur peram, kualitas fisik, dan kualitas kimia buah pisang Tanduk, kecuali susut bobot buah., Banana, aside from being a food ingredient, is important to Indonesia because it has cultural and socio-economic value. Banana has the advantage of being a commodity that is relatively easy and inexpensive to be cultivated. The fruit is not difficult to be processed and consumed by the household. This research is done to evaluate the accuracy of harvest using days after anthesis (DAA) converted into heat unit as the measurable harvest criteria for Horn banana. The experiment was carried out in Sukamantri Experimental Plantation, Bogor, West Java at an altitude of 550 m above sea level from January 2020 to May 2020. Postharvest quality testing of Horn bananas was carried out in Postharvest Laboratory, Department of Agronomy and Horticulture, Agricultural Faculty, IPB University until August 2020. This research was conducted in a completely randomized design with 5 replications to test 5 harvest ages: 50, 55, 60, 65, and 70 DAA. Those harvest ages are equivalent to the accumulated heat unit of: 965, 1067, 1134, 1201, and 1297 ˚C day. Experimental results show that difference in harvest age did not affect storage life, physical qualities, and chemical qualities, except for fruit weight loss.

Abstrak: The solution of Schrodinger equations with plasma Coulomb potential in spherical coordinat results solution wave function and energy plasma particle. Electron probability density at Debye length with thermal effect same as ion, which indicates plasma in neutral state. Electromagnetic waves perturbation of an electric field given to result wave function perturbation system. The probability density of plasma particle due to electromagnetic waves perturbation is the largest when an electromagnetic waves frequency 1.41 times the plasma frequency .
