Abstract

Deterioriation of palm oil fortified with vitamin A and provitamin A could be caused by the presence of oxygen and light exposure. The purpose of this study was to determine the effect of the initial peroxide value (PV) in palm oil (1.99, 3.98, and 9.95 meq O2/kg oil) and light intensity (15000, 10000, and 5000 lux) on the rate of oxidation and the shelf life of palm oil fortified with Red Palm Oil (RPO) equal to 45 IU vitamin A. The RPO contained β-carotene as provitamin A in the amount of 504.67 ppm. The PV and free fatty acid (FFA) content were observed as the parameters of oil deterioriation during storage. The results showed that the rate of PV was influenced by light intensity, while the rate of FFA formation were more influenced by the amount of initial PV in the oil. Based on the palm oil standard quality for PV (SNI 7709: 2012), the shelf life of palm oil with the lowest initial PV at ambient temperature was 9.5 days, while that with the highest PV was 1.32 hours. The deterioration rate of RPO fortified palm oil due to light exposure was also compared with its deterioration rate due to heat and the deterioration rate of palm oil fortified with vitamin A. The shelf life of vitamin A fortified palm oil stored in the dark was 90.67 days, while RPO fortified palm oil was 68.12 days. This shelf life results showed that RPO had a potency as provitamin A fortificant for palm oil as long as it is stored in a closed container in the dark.

Abstract

Corn (Zea mays) is one of the strategic commodities for a food-producing carbohydrates after rice. Beside that, corn is also used as animal feed, extracted oil, made of flour, and industrial raw materials. Obstacles encountered in increasing the productivity of corn are limited farmers in the allocation of factors of production, so that productivity is not optimal. This research obtain to determine the factors affecting productivity and efficiency of production factors on corn farming in District Lubuk Pinang Mukomuko. The method used is a survey method. Locations were selected purposively in Lubuk Pinang district Mukomuko. This research was conducted in June-August 2016. The sampling technique using proportional random sampling. Data analysis techniques to identify factors that affecting the productivity of corn used Cobb-Douglass production function and to analyze the efficiency of production factors used allocative efficiency. The results showed that with all the factors of production used very significant effect on the productivity of corn, while individually the factors of land, seeds, urea and Phonska very significant effect, whereas the amount of pesticides and labor not significant effect to the productivity of corn. The use of production factors pesticides and labor inefficient , while the use of land area, number of seeds, fertilizers urea and phonska under efficient.

Abstract

The events have been held in farmer Group Manggala Curup Village and farmer Group Melati Siguring Village, Sub-district North Curup, District Rejang Lebong. Most of farmers in Curup Village and Seguring Village, Sub -district North Curup, plant vegetable plants in monoculture and do not us e a good quality of seed. Farmers have good potential to improve the result and the income with avoiding crop failures or the plummeted of market price. These things will be able to be covered by other plants that can be obtained with intensive use of land by using multiple copping to vegetable plants that have high economy and use of good quality of seeds. The purpose of doing training are (1) farmer group has knowledge about intensification of land using multiple cropping and good quality of seeds (2) farmers are able to be producer of seeds in order to decrease the cost incurred in the next growing season and increace the income. The methods that will be used in training are (1) counselling and education about the agriculture of multiple cropping, good quality of seed, and the way to get good quality of seeds (2) production of demonstration plot (demplot) trial to apply multiple cropping and good quality of seeds. (3) Mentoring system of farmer group. The result of the activity is being able to improve insight of farmer, in the terms of intensification land by using multiple cropping and good quality of seeds. Besides that, farmers can produce their own seeds to the next growing season. The income of farmers in multiple cropping systems of vegetable plants will be higher if it is compared with monoculture system.Keywords: vegetable plant, multiple cropping, good quality of seed

Abstract

Kanker adalah sekelompok penyakit yang timbul apabila sebuah sel atau sekelompok sel lepas dari kontrol yang mengatur pertumbuhan. Ganggang hijau (Spirogyra sp.) merupakan salah satu tanaman obat yang digunakan sebagai obat tradisional untuk pengobatan kanker. Ganggang hijau (Spirogyra sp.) mempunyai kandungan zat aktif berupa melatonin dimana melatonin merupakan senyawa yang sudah diteliti para peneliti dunia sebagai obat antikanker dan antioksidan. Penelitian ini bertujuan untuk mengetahui pengaruh ekstrak etanol ganggang hijau (Spirogyra sp.) terhadap ekspresi COX-2 pada sel T47D. Ganggang hijau diekstraksi dengan menggunakan alat Soxhlet dengan pelarut etanol 96%. Penelitian ini menggunakan 3 kelompok yaitu kontrol sel, pemberian ekstrak etanol ganggang hijau konsentrasi 247,668 μg/ml dan 123,834 μg/ml. Untuk memastikan adanya ekspresi COX-2 dilakukan uji imunositokimia secara tidak langsung. Pengamatan dilakukan menggunakan mikroskop cahaya untuk melihat dan menghitung persen ekspresi COX-2. Hasil yang didapatkan menunjukkan terdapat perbedaan yang bermakna penurunan ekspresi COX-2 pada tiap kelompok.. Jadi dapat disimpulkan bahwa ekstrak etanol ganggang hijau (Spirogyra sp.) mampu menurunkan ekspresi COX-2 pada sel T47D.

Abstract

Gua dapat membentuk lorong-lorong yang rumit. Lorong yang terbentuk tersebut hasil proses yang panjang dalam skala geologi. Kenampakan yang ada saat ini berasal dari kondisi regional yang membentuknya. Tiap kondisi bentangalam memiliki bentukan lorong gua yang berbeda-beda. Identifikasi secara terperinci dilakukan dengan melihat kondisi lorong gua secara detail serta melihat secara keseluruhan. Kajian ini bertujuan untuk mengetahui pola lorong yang berkembang pada gua-gua di Kabupaten Malang. Metode pengumpulan data menggunakan data primer berupa unit-unit gua. Gua yang didata sebanyak 48 peta gua yang selanjutnya akan dilakukan analisis dengan pembagian, diantaranya curvilinear passage sebanyak 22 sampel, linear passage sebanyak 12 sampel, ceruk sebanyak 5 sampel, dan sumuran sebanyak 9 sampel. Analisis dilakukan dengan pendekatan kuantitatif dengan menggunakan softwere ArcGis, Spss, dan XLSTAT.  Dari hasil perhitungan dan identifikasi tersebut, memberikan gambaran mengenai pola yang berkembang di karst Kabupaten Malang yang memiliki 3 kondisi yaitu curvilinear, linier passage dan sumuran. Adanya tiga kondisi tersebut akan memiliki karakteristik yang berbeda, curvilinear akan membentuk zona vadose, epifreatik, dan freatik. Linier passage memiliki kondisi vadose dan epifreatik, sedangkan sumuran membentuk kondisi vadose.
