Judul: Mutasi Induksi Fisik Pada Coleus Spp. Dengan Iradiasi Sinar Gamma
Abstrak: Tanaman Coleus spp. merupakan tanaman yang dikembangbiakkan secara vegetatif. Mutasi induksi dengan iradiasi sinar gamma merupakan salah satu cara dalam meningkatkan keragaman genetik. Mutasi dapat meningkatkan keragaman genetik karena sifatnya yang spontan dan acak. Pemuliaan mutasi pada tanaman yang diperbanyak secara vegetatif telah menghasilkan tanaman-tanaman yang menarik terlebih pada tanaman hias. Tujuan dari penelitian ini untuk (1) mengidentifikasi respon keragaan vegetatif dan perubahan kualitatif tanaman Coleus spp. hasil iradiasi sinar gamma, (2) mengidentifikasi keragaman genetik tanaman Coleus spp. hasil iradiasi sinar gamma pada generasi MV2 dan MV3, (3) mendapatkan tanaman mutan Coleus spp. hasil iradiasi sinar gamma serta (4) mengetahui pengaruh iradiasi sinar gamma terhadap aroma, rasa dan kadar total flavonoid tanaman Coleus amboinicus Lour. Penelitian ini menggunakan Rancangan Acak Kelompok Lengkap (RAKL) faktor tunggal dengan tiga ulangan. Iradiasi sinar gamma diberikan terhadap 360 stek pucuk tanaman masing-masing dengan perlakuan iradiasi tunggal dan iradiasi terbagi. Iradiasi dilakukan di BATAN (Badan Tenaga Nuklir) Jakarta, Indonesia. Semua tanaman yang diradiasi di tanam di lapang. Perbanyakan tanaman Coleus spp. di generasi MV1 digunakan untuk generasi MV2 dan perbanyakan tanaman di MV2 digunakan untuk generasi MV3. Hasil penelitian menunjukkan bahwa pemberian iradiasi sinar gamma terhadap Coleus spp. menghasilkan variasi keragaan karakter vegetatif dan perubahan sifat kualitatif tanaman. Iradiasi sinar gamma dengan dosis tertinggi memperlihatkan rataan terendah pada karakter tinggi tanaman, jumlah daun, jumlah ruas, jumlah cabang, lebar daun dan panjang daun. Pemberian iradiasi sinar gamma pada Coleus spp. menghasilkan keragaman genetik yang tinggi pada karakter jumlah daun dan jumlah cabang. Induksi mutasi fisik dengan iradiasi sinar gamma pada Coleus spp. menghasilkan 16 variasi tanaman mutan berdasarkan perubahan warna dan corak daun. Coleus amboinicus Lour. menghasilkan 2 mutan yaitu pada tanaman A40.6 dan A35.12. Coleus blumei ungu/hijau menghasilkan mutan terbanyak mencapai 11 mutan yaitu pada tanaman A40.1, A40.8, A40.4, A40.12, A45.3, A50.5, T20+20.5, T20+20.7, T25+25.5, T22.5+22.5.8 dan T25+25.8. Coleus blumei merah menghasilkan 3 mutan yaitu pada tanaman A50.6, A50.12 dan T25+25.12. Pemberian iradiasi sinar gamma mempengaruhi perubahan aroma, rasa dan kadar total flavonoid pada tanaman Coleus amboinicus Lour. Kadar total flavonoid yang dihasilkan berkisar antara 0.09-0.29%, kadar total flavonoid tertinggi diperlihatkan pada tanaman A40.6 yaitu sebesar 0.29%.

Judul: Peningkatan Keragaan Coleus (Coleus sp.) melalui Induksi Mutasi Fisik dengan Iradiasi Sinar Gamma
Abstrak: The objectivse of this study were to see the effect in applicating several doses of gamma-ray irradiation (15, 30, 45, and 60 gray (Gy)), to obtain Lethal Dose 50 (LD50) values, and to gain new coleus performances in relatively short time. The study was conducted inside green house located at cikabayan experimental field, Bogor Agricultural University, Darmaga, Bogor on May to June 2013. The results showed that application of several doses of gamma irradiation on coleus were significantly different in character of height, number of leaves, and number of stem segment. Increasing the dose level of gamma irradiation given tend to inhibit the growth of the plants. Based on the result of the study, LD50 for yellow/green, green/brown, variegated green/brown of Coleus blumei, and Coleus amboinicus Lour were 48.66, 65.2, 52.81, and 37.62 Gy respectively. Coleus amboinicus Lour irridiated at a dose level of 45 Gy produced different leaf shapes compared to control.

Judul: Impact Of water policy on poverty reduction and women roles in water management In Zimbabwe
Abstrak: Water management is a key factor in the battle to remove the scourge of extreme poverty and to build secure and prosperous lives for people in the developing world. The water sector in Zimbabwe is complicated by the large number of actors; it is interwoven within various ministries. The research used secondary data and review of literature to evaluate how the current water policy has contributed towards marginalising women and the poor. It looked at how actors can also marginalise or put other actors at risk thereby undermining their role through prioritisation of certain projects, stakeholder participation and usage policy. From a descriptive analysis it is found that women are further relegated and marginalised. The poor are further impoverished through marginalisation and vulnerability. The policy environment favours business and state interests against those of grassroots actors and women. It recommends the establishment of home grown pro- poor water management strategies.
