Evaluasi Keragaman Kacang Bogor (Vigna Subterranea (L.) Verdcourt) Hasil Induksi Mutasi Kolkisin
Get PDFKacang bogor atau Bambara berasal dari Afrika, kemudian berkembang ke kawasan Amerika, Asia, dan Australia. Kacang bogor menjadi tanaman legume terpenting kedua dan merupakan tanaman pangan terpenting kedua setelah jagung dan kacang tanah di tingkatan petani subsisten di Mpumalanga Afrika. Tanaman kacang bogor memiliki kandungan lemak yang rendah, tetapi tinggi akan kalori membuat kacang bogor menjadi salah satu alternatif makanan untuk orang yang sedang diet lemak. Permasalahan yang menghambat peningkatan komoditas ini adalah belum dikenalnya tanaman ini di masyarakat menjadi salah satu kendalanya. Selain itu masih sedikitnya penelitian terhadap tanaman ini menjadi kendala berikutnya. Salah satu upaya untuk meningkatkan keragaman pada tanaman kacang bogor ialah dengan mutasi. Mutasi ialah perubahan dalam struktur gen baik yang terjadi secara spontan maupun secara buatan dengan menggunakan agensia fisik maupun kimia (Nasir, 2001) senyawa kimia yang dapat digunakan untuk menginduksi mutasi adalah kolkisin.
Tujuan penelitian ini ialah untuk mempelajari keragaman karakter kacang bogor hasil induksi kolkisin generasi CT-0 dan mempelajari penampilan karakter kacang bogor hasil induksi kolkisin generasi CT-0. Hipotesis penelitian ini ialah terdapat terdapat karakter yang beragam pada kacang bogor hasil induksi kolkisin generasi CT-0 dan terdapat karakter kacang bogor yang memiliki penampilan lebih tinggi dibandingkan dengan kontrol.
Penelitian ini dilaksanakan pada bulan Maret 2017 hingga Agustus 2017. Penelitian ini dilaksanakan di lahan percobaan Fakultas Pertanian, Universitas Brawijaya di Kelurahan Jatimulyo, Kecamatan Lowokwaru, Kota Malang. Penelitian Laboratorium dilaksanakan di Laboratorium Pemuliaan Tanaman, Fakultas Pertanian, Universitas Brawijaya. Bahan yang digunakan dalam penelitian ini antara lain kolkisin, media tanah, air, pupuk urea, SP36, KCl, pupuk kandang, pestisida dan benih kacang bogor galur GSG 2.1.1. Alat yang digunakan dalam penelitian ini antara lain gunting, spidol, kertas label, papan impraboard, ember, cangkul, cutter, micropipette, sarung tangan, masker, meteran, penggaris, timbangan analitik serta kamera digital. Penelitian ini menggunakan metode single plant. Konsentrasi kolkisin yang digunakan 0 ppm (kontrol), 100 ppm (P1), 300 ppm (P2) dan 500 ppm (P3). Waktu perendaman benih yang digunakan 3 jam (W1), 6 jam (W2) dan 9 jam (W3). Total tanaman yang digunakan sebanyak 144 tanaman. Parameter tanaman yang diamati antara lain tinggi tanaman (cm), jumlah daun (helai), Panjang akar (cm), Jumlah bunga, Umur berbunga (HST), Jumlah polong per tanaman, Bobot polong per tanaman, Jumlah biji per tanaman, Bobot biji per tanaman (gram) dan Umur panen (HST). Data yang diperoleh akan dianalisis menggunakan uji t, untuk mengetahui berbeda atau tidaknya individu akibat perlakuan dengan individu tanpa perlakuan.
Dari hasil analisis menunjukkan bahwa terdapat perbedaan nyata pada karakter lebar biji, panjang biji, lebar polong, panjang polong, lebar polong, jumlah biji serta jumlah polong akibat kombinasi perlakuan kolkisin dengan waktu perendaman. Perlakuan control memiliki kategori koefisien keragaman rendah, sedangkan kombinasi perlakuan kolkisin dengan waktu perendaman memiliki koefisien keragaman kategori rendah sampai tinggi

Analisis Insentif Terhadap Kinerja Pegawai Tetap dan Pegawai Perjanjian Kurun Waktu Tertentu
Get PDFCompetition between businesses that are increasingly intense, requires every company to be able to improve the quality of Human Resources (HR). Performance is still a concern for organizational and company stakeholders, because performance is the output displayed by each employee. One of the factors that affect the performance of an employee is the provision of incentives. The purpose of this study was to analyze the effect of providing incentives for jobholders on performance, to analyze the effect of providing incentives for PKWT employees on performance, and to analyze the effect of differences in the provision of incentives for permanent employees and PKWT. Data was collected through distributing questionnaires to employees of PT. Bukit Dhoho Indah Kediri, either directly or indirectly. The population used is 23 jobholders and 27 PKWT employees at PT. Bukit Dhoho Indah. The methods used to collect data are the documentation method and the questionnaire method. Data analysis in this study used simple regression analysis with the help of SPSS version 2.0. Testing of instrument data includes validity test, reliability test, F test and t test. The results of this study indicate that the provision of incentives has a significant effect on jobholders and PKWT employees, and the results of the t-test analysis show that PKWT employees have a value of 0.681 greater than jobholders with a t-test value of 0.478

Correlation between Facial Skin Damage Due to UV Exposure and Facial Skin Porphyrin Level: Study on Students of SMA Kalam Kudus II Jakarta, Indonesia
Get PDFBackground: UV exposure causes physical and chemical damage. UV causes damage to the skin barrier physically due to the heating process. Meanwhile, chemically, UV causes the formation of oxidants which are responsible for the process of oxidative stress. Damage to skin cells causes loss of the body's natural barrier against various threats from microorganisms. Propionibacterium acnes is one of the commensal bacteria on the skin, which will produce products in the form of porphyrins. This study aimed to determine the correlation between UV-induced skin damage and porphyrin levels in SMA Kalam Kudus II Jakarta, Indonesia.
Methods: This study was an analytic observational study with a cross-sectional approach. A total of 92 research subjects who were students of SMA Kalam Kudus II Jakarta, Indonesia, participated in this study. Facial skin porphyrin levels and levels of facial skin damage due to sun exposure (UV damage proportion) as measured by a skin analyzer. UV damage and porphyrin assessments according to the T Zone and V Zone regions and obtained the average results from the 3 regions. Correlation analysis was performed with the help of SPSS software.
Results: The higher the percentage of skin damage due to UV correlated positively with the higher the percentage of porphyrin levels, with a value of r = 0.529.
Conclusion: There is a positive correlation between UV-induced skin damage and porphyrin levels in students of SMA Kalam Kudus II Jakarta, Indonesia
