Judul: Penentuan Penciri Keragaman Konsumsi Pangan Rumah Tangga Rawan Pangan Dengan Metode Chaid Dan Exhaustive Chaid
Abstrak: Keragaman konsumsi pangan merupakan salah satu faktor yang menentukan status gizi individu juga masyarakat. Keragaman pangan individu dipengaruhi oleh karakteristik rumah tangga. Penelitian ini bertujuan untuk menentukan penciri keragaman pangan pada rumah tangga rawan pangan di Kabupaten Bogor. Metode yang digunakan adalah Chi-Squared Automatic Interaction Detection (CHAID) dan exhaustive CHAID. Metode CHAID merupakan analisis non parametrik yang dapat digunakan untuk melihat keterkaitan antar peubah yang memiliki peubah respon kategorik. Output dari analisis CHAID adalah pohon klasifikasi. Dasar pengambilan keputusan metode CHAID menggunakan nilai khi-kuadrat. Metode exhaustive CHAID merupakan pengembangan dari metode CHAID. Hasil penelitian menunjukkan bahwa karakteristik rumah tangga yang menjadi penciri keragaman konsumsi pangan pada rumah tangga rawan pangan adalah agroekologi, status pekerjaan ibu, dan jenis pekerjaan kepala rumah tangga. Peubah yang menjadi penciri keragaman konsumsi pangan pada metode CHAID tidak berbeda dengan metode exhaustive CHAID. Perbedaan terletak pada jumlah kelompok yang dihasilkan pada jenis pekerjaan. Jenis pekerjaan pada metode CHAID terbagi menjadi 3 kelompok sedangkan pada metode exhaustive CHAID terbagi menjadi 4 kelompok. Hal ini terjadi karena koefisien pengali Bonferroni pada metode exhaustive CHAID telah dilakukan penyesuaian sehingga menghasilkan penduga dengan tingkat kepercayaan yang lebih besar.

Abstrak: Household dietary diversity can be measured using Desirable Dietary Pattern (DDP), Household Dietary Diversity Score (HDDS), and modified HDDS. The general objective of this research is to compare several methods for assessing household dietary diversity. The specific objectives of this research were to identify characteristics of households, household food expenditure, and household dietary diversity; analyze correlation between household food expenditure and characteristics of households; and analyze correlation between household food expenditure and household dietary diversity based on DDP, HDDS, and modified HDDS. This research was cross-sectional study and used 118 households in Citayam and Babakan Village. This research was a part of research project “Validation of Modified HDDS (Household Dietary Diversity Score) for Recipient Household of Food Diversification Program in Bogor District” that was leaded by Dr Ir Yayuk Farida Baliwati, MS. Almost households in Citayam and Babakan Village was categorized as small household (59.32%). Fathers and mothers had low education level (36.44%, 44.92%). Fathers and mothers were categorized as middle adult (58.48%, 64.41%). Almost fathers worked as trader (25.42%) while mothers worked as housewife (73.73%). Almost households had high food expenditure level (50.85%). Household dietary diversity was high based on HDDS (95.76%) and modified HDDS (81.35%) but very low based on DDP (50.85%). Spearman correlation test showed that there were positive correlation between household food expenditure with education level of fathers (p=0.022 r=0.210), mothers (p=0.010 r=0.236), and total household members (p=0.003 r=0.275). Household food expenditure had positive correlation with household dietary diversity based on DDP (p=0.006 r=0.250) and HDDS (p=0.008 r=0.242). But household food expenditure didn’t correlate with household dietary diversity based on modified HDDS. Variation of dietary diversity based on DDP just could be determined by food expenditure about 3.9% (p=0.018 r2=0.039) but variation of dietary diversity based on HDDS could not be determined by food expenditure (p=0.061 r2=0.022). So, there was no recommendation method for assessing household dietary diversity.

Judul: Utilization of bone marrow mesenchymal stem cells for therapeutic model of epilepsy
Abstrak: Epilepsy is a chronic neurologic disease, caused by abnormal electrical activity in the brain. Uncontrolled medication using the currently available antiepileptic drugs may result in low quality of life. Bone marrow mesenchymal stem cell (bMSCs), one source of stem cell that is multipotent, can be given as an alternative treatment for intractable epilepsy. This research was aimed to (1) analyze the effect of chemical substance that can damaged the brain, to make a suitable animal model for epilepsy, (2) study of the culture bMSCs, and induced to become neurons in vitro neuron progenitor cells, before it can be transplanted to the animal model, (3) observe the effect of different dosages of bMSCs, and comparing the 2 routes of administration, through an intravenous line or a direct intracerebral approach. This study used 46 Spraque Dawley rats, aged 2 months which were divided to 7 groups consisted 6 rats each (1) negative control group, were given only 1ml NaCl 0.9% intravenous, (2) development of animal group model, 3 rats were given lidocaine 90mg/kg, 3 rats injected with bicuculine 8mg/kg, 1 rat was sacrificed each at the point of 24 hours, 3 days and 7 days after treatment, (3) positive epilepsy group, injected with bicuculine 8mg/kg intraperitoneally, and 3 rats were sacrificed each after 3 weeks and 6 weeks, (4-7) epilepsy group, after injected with bicuculine 8mg/kg intraperitoneally, at day-7 received bMSCs injection, each using 3x2x105 cell intravenous, 1x5x106 cell intravenous, neuron progenitor at 1x2x106 cell intravenous and neuron progenitor at 1x2x105 cell intracerebral. The result of this study showed that bicuculine injection, as a GABA-antagonist, was better when applied to create an epilepsy animal model. The most severe irreversible damaged occurred after the 7th day of treatment. The amount of cells of bMSCs culture at the 4th and 5th passages was sufficient to be transplanted, and the induction of neuron progenitor with basic fibroblast growth factor and epidermal growth factor was seen by noticing the change of the fibroblasts to neurons. The activity of bMSCs to regenerated neurons could be seen that injection of bMSCs 3x2x105 results the highest number of survived neurons. There was no systemic effect of bMSCs. From this study concluded that bMSCs improved regenerate the damage of hippocampal area caused by seizure in epilepsy model animals. A low dose, intravenous administration, given repeatedly every 2 weeks gives a better respon compared to a bolus with high dose intravenous and , intracerebrally. bMSCs treatment was better than progenitor neuron treatment.
