Judul: Hubungan Status Gizi Anak Usia Masuk Sekolah Dasar dengan Status Gizi Anak Balita dan Keadaan Sosial Ekonomi Keluarga
Abstrak: Status gizi dihitung menurut persen terhadap nilai baku antropometri WHO (1983), dengan menggunakan tiga macam indikator yaitu berat badan menurut umur, tinggi badan menurut umur dan berat badan menurut tinggi badan. Keadaan ekonomi keluarga diukur menurut jumlah pengeluaran keluarga perkapita sebulan. Analisa data diarahkan untuk melihat apakah prevalensi status gizi anak usia masuk sekolah dasar dapat digunakan untuk menggambarkan prevalensi status gizi anak balita. Kemudian juga ditinjau apakah nilai rata-rata status gizi anak usia masuk sekolah dasar dapat digunakan untuk menggambarkan nilai rata-rata status gizi anak balita. Selain itu ditinjau juga apakah status gizi anak usia masuk sekolah dasar berhubungan dengan keadaan sosial ekonomi keluarga. Untuk itu analisa hubungan dilakukan dengan uji khi kuadrat, analisa sensitifitas dan spesifisitas serta analisa regresi dan korelasi.

Judul: Pola sebaran bobot badan anak usia sekolah sebagai indikator status gizi
Abstrak: Status gizi sebagai indikator tingkat kesejahteraan masyarakat dapat digambarkan dengan pengukuran antropometri. Hasil pengukuran baru dapat disimpulkan bila dimiliki suatu rujukan baku, sehingga dapat dihitung proporsi anak dengan kategori gizi kurang, baik dan lebih serta diadakan perbandingan sebaran data antara populasi rujukan dengan populasi amatan. Tujuan penulisan karya ilmiah ini adalah untuk mengetahui bentuk pola sebaran mendekati ideal untuk indikator bobot badan terhadap umur, kemudian membandingkannya dengan pola sebaran yang dianggap berlaku berdasarkan standard NCHS serta mengadakan penilaian untuk standard NCHS ini. Data yang digunakan adalah data bobot badan anak usia sekolah, yang merupakan data sekunder dari hasil penelitian Jurusan Gizi Masyarakat dan Sumberdaya Keluarga Fakultas Pertanian IPB bekerja sama dengan Direktorat Bina Gizi Masyaraket Departemen Kesehatan RI pada bulan Juli tahun 1988. Pengesahan dan penyuntingan dilakukan terhadap data pengamatan awal. Diagram kotak garis dan diagram..dst

Judul: Telosma mosaic virus associated with mosaic disease of patchouli plant: identification and control approach
Abstrak: Patchouli oil (patchouli alcohol) produced by patchouli plant (Pogostemon cablin Benth.) is one of the raw materials of high value multifunctional perfume. However, in the process of cultivation and development of this commodities are attacked by plant pest organisms, especially diseases. Some important diseases of patchouli, which is now spread in Indonesia, namely budok, bacterial wilt, diseases caused by nematodes and viruses. This study aimed (1) to map the presence of mosaic disease on patchouli plantation in patchouli production centers of Indonesia, (2) to measure product reduction of patchouli plants due to mosaic disease, (3) to identify viruses associated with mosaic disease, (4) to identify aphid species found colonizing patchouli plants in the field, (5) to molecularly characterize viruses associated with mosaic disease on patchouli, (6) to analyze the genetic diversity among Telosma mosaic virus (TeMV) isolated from patchouli, (7) to determine the host range of TeMV, (8) to determine the relationship of the aphids colonizing patchouli plants with mosaic disease, and (9) to obtain virus-free patchouli seedling by apical meristem culture method and hot water treatment. The results show that the mosaic disease was found in all patchouli production areas of Java and Sumatra and two species of aphids, i.e. Aphis gossypii Glover and Brachycaudus sp. were found colonizing patchouli plants in all survey locations. Due to the mosaic disease, reduction of fresh herbs weight, dry herbs weight, oil content and the patchouli alcohol of patchouli in the first harvest was reached 35%, 40%, 9% and 5%, respectively. Based on the serological test, Potyvirus was found predominantly associated with the mosaic symptoms. Further identification based on nucleotide sequence of coat protein gene revealed that the species of Potyvirus is Telosma mosaic virus (TeMV). Host range and aphid transmission evaluation confirmed the association of Potyvirus with mosaic disease. This paper is the first report of occurence of TeMV in Indonesia. This virus will be easily to spread to any areas because patchouli plants are propagated by stem cuttings. In this study, a technique was also developed to produce virus-free cutting using apical meristem culture and hot water treatment on stem cutting. The patchouli plant has been propagated from apical meristem culture of 0.5-1 mm in sizes yielded 33.3-90.9% virus-free plants. Submersion of patchouli stem cutting in hot water of 50-60⁰C for 10-30 minutes could not eliminated TeMV. Apical meristem culture technique is potential to produce virus-free cutting of patchouli.
