The results of this study shows that the level of nutrition knowledge is fair (40%) and the majority have normal nutritional status (96.9%). Most of the energy adequacy level examples are categorized highly deficit, while protein adequacy is normal. Iron and vitamin C adequacy are insufficient, whereas vitamin A adequacy is categorized sufficient. 68.75% of samples chose a positive perception of body image.

Judul: Chilli Veinal Mottle Potyvirus (ChiVMV) the causal agent of mottle diseases on Chilli Pepper (Capsicum annuum L.): isolates diversity and its control strategy through induction of somaclonal variation.
Abstrak: Chilli veinal mottle potyvirus adalah salah satu virus utama yang menyerang tanaman cabai. Walaupun keberadaannya di Indonesia tergolong baru, namun penyebarannya dapat ditemukan hampir disetiap pertanaman cabai. Infeksi ChiVMV dapat mengakibatkan penurunan hasil 50% hingga 100%. Untuk mengatasi terjadinya ledakan penyakit, menggunakan varietas yang tahan terhadap virus merupakan salah satu alternatif. Namun sampai saat ini belum diperoleh varietas cabai tahan ChiVMV. Bila sumber gen ketahanan terhadap virus masih terbatas, maka salah satu upaya peningkatan sumber gen ketahanan tersebut dapat dilakukan melalui induksi keragaman somaklonal yang dikombinasi dengan induksi mutasi.
