Judul: Studi Kejadian Sistiserkosis Pada Babi yang Dijual di Pasar Jibama Kabupaten Jayawijaya Papua.
Abstrak: Taeniasis/cysticercosis due to T. solium infection is one of the most serious public health problem in Jayawijaya Regency-Papua. This survey was carried out to study prevalence of cysticercosis in pigs that were slaughtered and sold in Jibama Market of Wamena-Jayawijaya. Association between the porcine cysticercosis prevalence and pig farming practices and environmental sanitation in pig producer districts was also examined in this survey. Results of the survey showed that 77.1% of pigs slaughtered in Jibama Market was infected by Cysticercus cellulosae. Such high prevalence of cysticercosis in pig meat market may play important role in taeniasis transmission among people in Jayawijaya, as this study also revealed that most of peoples consumed raw (4.8%) or undercooked meat (44.8%). Majority of families in villages owned pigs (65.7%) which were free ranged pigs. This traditional farming system provide an opportunity for pigs to pick up T. solium eggs/gravid proglottids shed through feces of the infected peoples. Habit of local people (86.1%) to defecate in backyards due to lack of latrine facilities is of important in contamination of T. solium eggs/gravid proglottids in environment. This study also found significance association between prevalence of porcine cysticercosis and farm management system and possession of latrine facilities.

Judul: Considerable study of epidemiology porcine cysticercosis and risk characterization of pork meat by burning stones at Jayawijaya Regency Papua
Abstrak: Jayawijaya Regency is a hyperendemic area of human cysticercosis in Indonesia. Disease caused of metacestoda of Taenia solium. Therefore very limited data of porcine cysticercosis are available. This study was divided into three stages, the first to assess the spread of porcine cysticercosis in Jayawijaya Regency, second to characterize the risk of burning stones (barapen), the last was examined the level of knowledge and behavior about the source of tapeworm infection. A total of 111 pigs were tested serologically to detect the presence of circulating parasite antigen using monoclonal antibody-based sandwich enzyme-linked immunosorbent assay (MoAb-ELISA). Fourty five samples (40.54%) were found positive by MoAb-ELISA, and the highest prevalence occurred from the District of Asolokobal (92.86%), followed by Musatfak (75%), Kurulu (65.22%), Bolakme (33.33%), Asologaima (31.82%), Homhom (18.18%), Hubikosi (14.29%), Jibama market (14.29%), and the lowest prevalence from Wamena Kota (5.88%). Free-range pig husbandry system (OR=4.63; P<0.01) and uncooked pork feed (OR=3.65; P<0.05) were important risk factors for porcine cysticercosis. Asolokobal District are highly vulnerable to cycticercosis. Barapen is one of culture in Jayawijaya. The research was conducted to study the relationship between barapen method and infecting humans with cysticercosis/taeniosis. Field observations indicate a barapen is divided into three parts, namely, stone and wood burning, roasting pork and eat together. The highest hot stones temperature is 300 °C and lowest 170 °C. The roasting pork take more an hour with a temperature of 60 to 90 °C. The temperature of the stone (65.66 °C) and pork (83.33 °C) removed from the barapen process were highly. The pork was cooked only spread on the grass. Opportunity to get cysticercosis in Wamena is currently puting the food that cooked on the grass. Health education were done at 41 housewives in Wamena. Overall there is an increasing public knowledge of cysticercosis after the intervention through counseling about cysticercosis is 75.28% to 100%. Differences in knowledge there is very high at the time of education is given between 58.54% and 76.61%. After one week of the results obtained do counseling is an increase in the knowledge that is not too high (36.59%). Behavioral people after an education increase of 21.39%. Health education is conducted continuously to reduce the prevalence of cysticercosis/taeniosis in Jayawijaya. The needed for counseling regarding methods of handling food hygiene, an anthropology approach about pig husbandry system and pattern of cook pork feed.

Judul: Katalis Zink Ferit Tersubstitusi Cu untuk Oksidasi Benzil Alkohol
Abstrak: Katalis berperan dalam menurunkan energi aktivasi. Katalis ZnFe2O4 dan ZnFe2O4 tersubstitusi Cu disintesis menggunakan metode kopresipitasi untuk digunakan dalam oksidasi benzil alkohol. Katalis dicirikan dengan spektrofotometer inframerah (FTIR) dan difraktometer sinar-X. Spektrum FTIR menunjukkan puncak serapan dari ikatan Zn-O dan Fe-O masing-masing pada rentang 559‒575 cm-1 dan 419‒447 cm-1. Difraktogram menunjukkan terbentuknya fase tunggal Zn0.6Cu0.4Fe2O4 pada katalis ZnFe2O4 tersubstitusi Cu 20%. Benzil alkohol dioksidasi dengan sistem refluks. Konversi benzil alkohol meningkat dengan meningkatnya suhu. Kadar benzaldehida yang dihasilkan dengan katalis ZnFe2O4 tersubstitusi Cu 20% lebih tinggi dibandingkan dengan katalis ZnFe2O4 yang tidak tersubstitusi dan yang tersubstitusi Cu 60 dan 80%. Hal tersebut menunjukkan bahwa katalis ZnFe2O4 tersubstitusi Cu 20% memiliki kinerja yang lebih baik dalam oksidasi benzil alkohol menjadi benzaldehida dengan kadar benzaldehida 8.763%.
