Abstract

Beberapa jenis bawang putih dapat dijumpai di pasaran, yaitu : bawang putih yang baik, bawang putih yang ditumbuhi kapang, dan bawang putih ‘abangan’. Penelitian terhadap tiga jenis bawang putih ini menunjukkan kadar air sebagai berikut : bawang putih yang baik 61,24 %, bawang putih yang ditumbuhi kapang 69,58 %, dan bawang putih ‘abangan’ 11,27 %. Penelitian mikrobiologis menggunakan Direct Plating menemukan 11 jenis kapang pada bawang putih yang ditumbuhi kapang dan 3 jenis kapang pada bawang putih ‘abangan’. Keberadaan kapang yang didominasi oleh genera Aspergillus menyebabkan tingginya resiko mengkonsumsi bawang putih tersebut, karena dapat dihasilkannya mycotoxin berupa Aflatoksin oleh kapang dari kelompok Aspergillus ini.

Abstract

Produksi susu sapi yang melimpah tidak diikuti dengan permintaan yang tinggi dari  masyarakat sehingga banyak produk susu sapi yang tidak termanfaatkan. Susu sapi yang masih segar maupun yang sudah rusak memiliki kandungan kasein yang cukup tinggi. Kasein termasuk polimer alami sehingga dapat dimanfaatkan sebagai bahan utama pada pembuatan cat emulsi. Pada pembuatan cat emulsi, faktor yang harus diperhatikan adalah kestabilan emulsi. Maka, penelitian ini bertujuan untuk mengetahui pengaruh jumlah pengemulsi (1 gram, 2 gram, 3 gram, dan 4 gram) yang digunakan terhadap karakteristik cat yang meliputi ukuran partikel, waktu kering, viskositas, daya rekat, dan kekerasan. Hasil uji statistik (Uji F) menunjukkan bahwa jumlah pengemulsi memiliki pengaruh terhadap karakteristik cat yang meliputi ukuran partikel, waktu kering, viskositas, daya rekat, dan kekerasan. Hasil penelitian dengan menggunakan uji statistik (Uji F) menunjukkan bahwa jumlah pengemulsi berpengaruh nyata terhadap karakteristik viskositas, ukuran partikel, waktu kering, dan tingkat kekerasan, serta jumlah pengemulsi berpengaruh sangat nyata terhadap karakteristik daya rekat cat. Cat emulsi berbasis kasein dan kapur tohor dengan penambahan bahan pengemulsi CMC sebanyak 4 gram memiliki kualitas yang terbaik, yaitu nilai kekerasan 4 H, daya rekat 97,5%, waktu kering 38,5 menit, ukuran partikel 8,75 mikron, dan viskositas 450 d.Pa.s.   The abundant cow's milk production is not followed by high demand from the public so that many cow's milk products are not utilized. Cow's milk that is still fresh or that has been spoiled has a fairly high casein content. Casein is a natural polymer so it can be used as the main ingredient in the manufacture of emulsion paints. The factor that must be considered in the manufacture of emulsion paint is the stability of the emulsion, thus this study aims to determine the effect of the amount of emulsifier (1 gram, 2 gram, 3 gram, and 4 gram) used on the paint characteristics which include particle size, dry time, viscosity, adhesion, and hardness. Statistical test results (Test F) showed that the amount of emulsifier has an influence on the characteristics of the paint which includes particle size, drying time, viscosity, adhesion, and hardness. The results of the study using statistical tests (Test F) showed that the amount of emulsifier had a significant effect on the characteristics of viscosity, particle size, dry time, and level of hardness, and the amount of emulsifier had a very significant effect on the characteristics of paint adhesion. Casein and quicklime based emulsion paint with the addition of 4 grams of CMC emulsifier has the best quality, namely 4 H hardness, 97.5% adhesion, 38.5 minutes dry time, 8.75 micron particle size, and 450 viscosity. d.Pa.s.

Abstract

Mosquitoes are group of insect with an impact to human health. Female mosquito has a habit of blood feding for maturing their eggs after mating. Mosquito-borne diseases might be transmitted during their blood sucking activity. Filariasis is a mosquito-borne diseases which has plagued Indonesia since long time and can still be found in the east part of Indonesia. Therefore mosquitoe population control had been an important issue in Indonesia.. Larvacides application is one of the most effective method to control mosquitoes spread by cutting their life cycle. Larvicides can be either synthetic or natural. One of the natural materials that can be used as larvicide is papaya leaves. This study objective was to compare the effectiveness of papaya leave and temephos 1% in killing mosquito larvae. This type of research is experimental with purposive sampling technique.

Abstract

Cabbage (Brassica oleracea var. capitata) is commonly consumed in raw as lalapan (secondary dish) in daily meal. Lalapan is raw vegetables which is commonly consumed in Javanese people as secondary dish. Consumption of raw vegetables has a potential for helminth infection. This research is an experimental study. In this study, three methods of washing cabbage by using running water, submerged water, and submerged brine were carried out. Different treatments aim to find out more effective methods in preventing the transmtion of parasitic helminths through cabbage vegetables. In the washing method using running water, it is hoped that worm eggs will be washed away along with the dirt in the cabbage vegetable strands. In the washing method using submerged water, it is hoped that worm eggs can be detached from the strands of cabbage vegetables and float on the surface of the water used for washing. Meanwhile, in the washing method using submerged brine, it is expected that the worm eggs will fall and settle at the bottom of the washing container. Chi-square test result in p value = 0,273 between washing method using submerged water and submerged brine, which can be interpreted as there is no difference in contamination results between the washing method using submerged water and submerged brine. Running water gave the best result with no contamination found in cabbage leaves.
