Pengujian Konsumsi Listrik Dan Suhu Dalam Lemari Pendingin Skala Rumah Tangga Pada Kondisi Riil

Tulisan in melaporkan hasil pengujian terhadap suatu sampel lemari pendingin yang ditempatkan pada sebuah rumah tangga untuk meneliti suhu di dalam lemari pendingin dan konsumsi energinya. Rumah tangga yang dijadikan lokasi pengujian berpenghuni 4 orang dengan pendapatan total berkisar Rp. 3–5 Juta/bulan. Lemari es yang diuji ini merupakan lemari es kedua yang ada di rumah tersebut. Selama pengujian seluruh anggota keluarga dibebaskan untuk menggunakan lemari pendingin sebagaimana layaknya sesuai buku petunjuk pabrikan. Pengujian ini amat menarik mengingat pengujian lemari pendingin selama ini selalu dikondisikan, baik tegangan listrik, suhu ambien, kelembaban udara maupun cara pengoperasiannya. Hasil pengujian menunjukkan adanya perbedaan konsumsi energi yang besar dibandingkan dengan hasil pengujian terkondisikan pada sampel yang sama. Demikian juga dengan unjuk kerjanya yang dipresentasikan oleh suhu rata-rata pada masing-masing kompartemen dalam lemari pendingin. Terdapat selisih suhu sebesar + 5oC antara kedua sistem pengujian ini

The seasonal survey of copepodes density and distribution in the southern parts of the Caspian Sea

To investigate the distribution of Copepodes in the southern basin of the Caspian Sea, in 1991 and 1992, 16 station along the shore and 8 stations in depths below 100 meters were set up. In all station two suborders, Viz, Calonoida and Cyclopoida, at different stages of life cycles were observed. Results show the Copepodes density decreases as the distance from shore increases, the density is also higher in the eastern and western parts than the central part of the sea. Calonoida and Nauplius density in all station were higher than Cyclopoida. While the maximum density of Nauplius occurred in the surface, the highest density of Cyclopoida and Calonoida was observed in deeper parts

Inhibitory effect of citric acid on rancidity of frozen catfish (Silurus glanis)fillets

The effect of aqueous solution of citric acid (CA) on the lipid stability of the European catfish (Silurus glanis) fillets during frozen storage (up to 6 months) was investigated. Rancidity development was measured by several biochemical indices (free fatty acids, peroxides and TBA) and complemented by the measurement of expressible moisture and sensory evaluation (flesh odor, consistency and flesh appearance). The CA treatment led to some lower free fatty acids (6.43% oleic acid in total lipid at month 6), peroxides (7.98meq oxygen/kg lipids, at month 6) and secondary compounds formation (2.16mg malondialdehyde/kg fish sample). Lower peroxide, thiobarbituric acid-reactive substance (TBA), free fatty acids (during 0,3 and 6 months frozen storage), and expressible moisture (month 6) values were obtained from CA-treated fish fillets than the untreated (blank control) ones (P<0.05)

Analisis Faktor yang Mempengaruhi Produksi USAhatani Jagung Serta Efisiensi Teknis di Kabupaten Kupang

Corn (Zea mays L.) is a potential agribusiness commodity in meeting food needs. In the national economy, corn is the second largest contributor after rice in the food subsector. One potential area for corn production is Kupang Regency which has a lot of marginal lands (dry land). This study aims to determine the factors that influence the production and technical efficiency of corn farming in Kupang Regency. This study, using the Cobb-Douglas production function method, is a functional form of the corn production function in the study area and the Stochastic Frontier method is estimated using the Ordinary Least Square (OLS) and Maximum Likelihood Estimation (MLE) methods. The results showed that all the variables in the significant model were soil, seeds, Urea, KCL, SP36, pesticides and had signs that matched expectations. The study also found that farmers were technically efficient with an average of 75 percent and factors that had a significant influence on increasing technical personnel, namely age, formal education and income

KAJIAN LITERATUR CANINE PARVOVIRUS PADA ANJING

Canine parvovirus merupakan penyakit infeksius yang menyerang saluran pencernaan, disebabkan oleh canine parvovirus tipe 2 (CPV-2). Karakteristik virus parvo yang sangat stabil memungkinkan virus ini tetap berada di lingkungan. Infeksi Canine parvovirus dapat terjadi secara langsung maupun tidak langsung. Penyakit parvovirus pada anjing terdiri dari 2 tipe gejala klinis, yaitu tipe miokarditis dan Enteritis. Diagnose dilakukan berdasarkan anamnesa, gejala klinis, pemeriksaan patologi anatomi dan pemeriksaan diagnosis laboratorium berupa tes kit, Enzyme linked immunosorbent assay (ELISA), polymerase chain reaction (PCR), Fluorescent antibody technique (FAT). Terapi yang diberikan berupa pemberian terapi cairan dan pemberian antibiotik untuk mencegah infeksi sekunder

Determination of Aluminium and Physicochemical Parameters in the Palm Oil Estates Water Supply at Johor, Malaysia

The study was to determine the concentration of aluminium (Al) and study the physicochemical parameters (pH, total dissolved solids (TDS), turbidity, and residual chlorine) in drinking water supply in selected palm oil estates in Kota Tinggi, Johor. Water samples were collected from the estates with the private and the public water supplies. The sampling points were at the water source (S), the treatment plant outlet (TPO), and at the nearest houses (H1) and the furthest houses (H2) from the TPO. All estates with private water supply failed to meet the NSDWQ for Al with mean concentration of 0.99 ± 1.52 mg/L. However, Al concentrations in all public water supply estates were well within the limit except for one estate. The pH for all samples complied with the NSDWQ except from the private estates for the drinking water supply with an acidic pH (5.50 ± 0.90). The private water supply showed violated turbidity value in the drinking water samples (14.2 ± 24.1 NTU). Insufficient amount of chlorination was observed in the private water supply estates (0.09 ± 0.30 mg/L). Private water supplies with inefficient water treatment served unsatisfactory drinking water quality to the community which may lead to major health problems

DESKRIPSI MORFOLOGIS NEMATODA SALURAN PENCERNAAN KAMBING KACANG (Capra hircus aegagrus) DI KOTA KUPANG-NUSA TENGGARA TIMUR

Local Goats (Capra hircus aegagrus) is a type of small ruminants and is a home-grown in Indonesia which is very susceptible to attack by diseases caused by gastrointestinal parasites, especially in developing countries, causing losses to infected animals and economic losses to farmers. This study aims to know the morphology and total of eggs and adult worms, in the digestive tract in Kupang City- East Nusa Tenggara. This study uses work methods including total calculation and identification of worm eggs using the McMaster method, aiming to calculate the number of worm eggs and used to identify the morphology of worm eggs, total testing and morphology of adult worms in the digestive tract aims to determine the number of adult worms in the digestive tract, Semichenetic Acetic Camine staining aims to confirm and clarify the type from the results of identification of adult worms found in goat intestines after it is determined the dominant type of adult worms in the digestive tract of local goats. The results showed that there were three types of worm eggs found from 20 local goats, namely Trichuris sp as many as 5, Strongyloides sp as many as 63, and Strongyloid sp as many as 304 and there were three categories of infection, namely infection-free category in two goats (TTGT = 0), mild infections in three goats (TTGT = 300-400 or ranged from 1-499), and moderate infections in 15 goats (TTGT = 500-2850 or ranged from 500-&gt; 5000). The results of the total study of adult worms in the digestive tract from four local goats found one type of digestive tract worms, namely Trichuris sp as many as 120 of the two goats (numbers 2 and 4). Trichuris sp as the most dominant type of worm in the digestive tract of local goats in Kupang City, East Nusa Tenggara
