Abstract

Cabai hias sebenarnya sudah cukup lama dikenal oleh masyarakat Indonesia. Namun, produksinya masih rendah karena kendala rasa yang tidak begitu pedas. Oleh karena itu, diperlukan suatu upaya peningkatan keragaman cabai hias untuk mendapatkan genotipe baru cabai hias baru yang tidak hanya cantik namun memiliki rasa yang pedas. Salah satu kegiatan untuk meningkatkan keragaman genetik cabai adalah dengan persilangan.  Penelitian dengan judul "Peningkatan Keragaman Genetik Cabai Hias dengan Persilangan Diallel" bertujuan untuk (1) mengetahui tingkat keberhasilan persilangan antar tetua, (2) mempelajari rekombinasi karakter pada pasangan persilangan,  serta (3) mendapatkan informasi penggunaan tetua yang tepat dalam menghasilkan varietas baru cabai hias. Penelitian dilakukan di Kebun Percobaan Program Studi Agroekoteknologi. Penelitian ini menggunakan dua varietas cabai pedas (Katokon dan Pelita) serta satu varietas cabai hias Ayesha IPB dan tujuh genotipe cabai hias (TR3, TR19, TR23, TR23B, TR25H, dan TR25U) yang merupakan koleksi cabai hias milik Universitas Trilogi,. Pengamatan yang dilakukan adalah persentase keberhasilan persilangan antar tetua, karakter kualitatif dan kuantitatif hasil persilangan. Hasil penelitian menunjukkan bahwa keberhasilan persilangan dari 1.757 kali persilangan yang berhasil memasuki masa panen hanya 29 buah, dengan persantase tertinggi mencapai 6.9% pada pasangan tetua K x TR19 sedangkan terendah 1.2% pada tetua TR19 x A dan P x TR19. Perakitan varietas cabai hias telah berhasil dilakukan dengan menunjukkan beberapa karakter yang diharapkan. Selain itu, diperoleh juga informasi bahwa rata-rata varietas dan genotipe cabai mampu dijadikan sebagai tetua betina.

Abstract

Penggunaan krim tabir surya berbahan dasar senyawa sintetik pada sebagian orang dengan jenis kulit sensitif dalam jangka waktu lama dapat menimbulkan alergi serta iritasi kulit. Untuk mengatasi hal tersebut salah satu usaha yang dapat dilakukan adalah dengan modifikasi krim tabir surya dengan bahan alami yang mempunyai aktivitas antioksidan sehingga diharapkan lebih aman dan efektif melindungi kulit dari radikal bebas. Katekin merupakan salah satu senyawa yang telah dilaporkan memiliki aktivitas antioksidan, oleh karena itu penelitian ini bertujuan untuk mempelajari efektivitas krim tabir surya yang mengandung senyawa katekin gambir dan teh hijau yang ditentukan dengan nilai sun protection factor. Formulasi krim tabir surya masing-masing dibuat dengan konsentrasi katekin 0,215% b/b. Karakterisasi krim tabir surya meliputi uji organoleptis, homogenitas, pengukuran pH, dan daya sebar. Selain itu, krim juga diuji stabilitasnya dengan cycling test dan centrifugal test. Nilai Sun Protection Factor dianalisis menggunakan metode spektrofotometri dengan pengenceran etanol 96%. Kalkulasi nilai SPF dilakukan dengan metode Mansur. Dari uji organoleptis terlihat bahwa warna dari setiap krim tabir surya sama dengan warna bahan yang digunakan. Penambahan katekin tidak memberikan pengaruh nyata terhadap nilai pH krim tabir surya. Daya sebar dari basis krim maupun krim yang mengandung senyawa katekin tidak berbeda nyata dan ketiga krim tersebut termasuk sediaan krim yang stabil serta tidak memiliki pemisahan fase emulsi. Nilai SPF dari krim tabir surya yang mengandung senyawa katekin gambir maupun teh hijau tidak jauh berbeda dengan nilai SPF dari basis krim dan krim tabir surya komersial.Kata Kunci : Camelia sinensis, Uncaria gambir, katekin, spektrofotometri, SPF, tabir surya Camelia sinensis, Uncaria gambir, katekin, spektrofotometri, SPF, tabir surya

Abstract

Biodelignification is a preliminary process of removing lignin from lignocellulosic materials using microorganisms. In the textile industry, the enzymes produced by fungi are used to degrade synthetic dyes in waste, soil bioremediation, biodegradation of phenol pollutants in the environment, and pulp and paper processing. (Mosier. Et al., 2005). Indigenous fungi are fungi that have the ability to degrade organic compounds and make them a source of nutrients for metabolism and life (Raju, et al., 2007). Fungi were chosen as one of the organisms for Biodelignification because they are able to degrade toxic components by means of transformation, namely changing the hazardous chemicals that are formed in the soil (Sullia, 2000). Fungi can survive in various environments on different media including soil. Wastes with various organic compounds are difficult to degrade due to their polymer shape, and only a small amount can be hydrolyzed due to their composite and complex structure. Some indigenous fungi that live in the soil have the ability to break down various organic compounds including lignin and cellulose. This fungus produces ligninase, which is an enzyme that can break down lignin and cellulase compounds (Yang et al., 2005, Guang et al., 2006). This research was conducted to obtain fungal isolates that have the ability to degrade lignin. Isolation is taken from soil sources contaminated with textile waste, isolated using lignin selective media with tannic acid as the sole C source. The method used in this research is descriptive exploration method in field sampling and experimental method for laboratory observations, namely the isolation and culture of fungi by dilution method, then identification of fungal genus is carried out by the Moist Chamber method, while the properties and morphology are described descriptively based on literature guide Introduction To Food-Borne Fungi (Samson et al., 1995). The results obtained 11 isolates of fungi that have ligninolytic abilities. Genus Aspergillus, sp. has the highest ligninolytic ability by producing a clear zone diameter of 3.45 cm on the 3rd day.

Abstract

Sweet corn is a horticultural commodity that has a high carbohydrate source. The need for this commodity continues to increase every year, while the production results produced by farmers have not been able to meet those needs. Efforts need to be made to increase the production of sweet corn, one of the efforts that can be done is to utilize mechanical technology, the use of mutation techniques in corn plants to assemble the genetic traits of varieties through mutations with radiation. This research aims to get the best treatment between sweet corn lines and gamma ray irradiation dose on yield components. This research was carried out in PT. Pertani, Telukjambe Karawang District start in May 2019 until September 2019.The research method used was an experimental method using factorial randomized block design. There are two factors consisting of 20 treatments. The first factor is sweet corn strain consisting of 5 lines, namely MS-09, MS-010, MS-011, MS-012 and MS-014. The second factor is the dose of gamma ray irradiation which consists of 4 levels, namely M0 (0 gy), M1 (100 gy), M2 (200 gy) and M3 (300 gy). Each treatment was repeated 2 times so that in total there were 40 experimental units. The effect of the treatment was analyzed by variance and if the F test level of 5% was significant, then to find out the best treatment continued with a further DMRT (Duncan Multiple Range Test) test at the 5% level. There is an treatment effect between sweet corn genotype and gamma ray irradiation dose, the best effect is on the treatment of G7M1 (strain MS-010 and irradiation dose 100 gy) in all parameters of observation, weight of cob with kelobot (192.02 gr), weight of cob without cob (133.12 gr), length of ear with cob (192.12 gr) 26.19 cm), the length of the ear without cob (17.35 cm), and the diameter of the ear without cob (4.16 cm).
