PENENTUAN TOTAL FENOLIK DAN UJI AKTIVITAS ANTIOKSIDAN PADA BIJI DAN KULIT BUAH PINANG YAKI (Areca vestiaria Giseke)ABSTRAK Telah dilakukan penelitian untuk menentukan kandungan total fenolik dan menguji aktivitas antioksidan pada biji dan kulit buah pinang yaki. Ekstrak biji dan kulit buah pinang yaki diperoleh dengan maserasi tanpa sokletasi dan maserasi setelah sokletasi. Total fenolik diuji dengan metode Folin-Ciocalteu dan uji aktivitas antioksidan dengan metode DPPH. Hasil penelitian yang diperoleh, kandungan total fenolik Maserasi Biji Setelah Sokletasi, Maserasi Kulit Setelah Sokletasi berturut-turut memiliki nilai sebagai berikut : 85,92 mg/kg, 3,16 mg/kg. sedangkan aktivitas antioksidan Maserasi Biji Setelah Sokletasi, Maserasi Kulit Setelah Sokletasi berturut-turut memiliki nilai sebagai berikut : 88,16%, 54,11%. Kata kunci : Antioksidan, Areca vestiaria Giseke, DPPH, Total Fenolik   TOTAL PHENOLIC COMPOUNDS AND ANTIOXIDANT ACTIVITY OF THE SEED AND SKIN OF PINANG YAKI (Areca vestiaria Giseke) FRUITS ABSTRACT This research has been conducted to measure the total phenolic compounds and the antioxidant activity of the seed and skin of pinang yaki fruits. The samples of the seed and skin were prepared separetely by maceration and soxhlet extraction followed by maceration. Folin-Ciocalteu method was used to measure the total phenolic compounds of while DPPH (1,1-diphenyl-2-pikrilhidrazil) method was used to measure the antioxidant activity. The total phenolic compounds of the seed by soxhlet extraction followed by maceration, skin by soxhlet extraction followed by maceration and were 85,92 mg/kg, 3,16 mg/kg respectively. The antioxidant activity of the seed by soxhlet extraction followed by maceration, skin by soxhlet extraction followed by maceration and were 88,16%, 54,11% respectively.

Telah dilakukan penelitian untuk mengetahui kualitas VCO sebagai minyak goreng yang dibuat dengan menggunakan metode pengadukan dengan adanya penambahan kemangi (Ocimum sanctum) serta perbandingannya dengan VCO tanpa penambahan kemangi. Parameter kualitas yang diuji yaitu bobot jenis, bilangan peroksida, dan asam lemak bebas (FFA). Hasil penelitian menunjukkan bahwa penambahan kemangi tidak memberikan pengaruh yang baik terhadap kualitas VCO karena kualitas VCO kontrol lebih baik dibandingkan VCO kemangi pada semua tahap penggorengan.A research had been conducted to determine the quality of VCO as cooking oil, prepared by mixing method, which was added with basil (Ocimum sanctum) and to compare it with VCO without basil. Parameters tested were specific weight, peroxide number, and free fatty acid. The results showed that the addition of basil did not give a good effect on the VCO quality which was reflected in the lower quality of basil-added VCO than that of VCO without basil at each frying stage.

Kualitas Virgin Coconut Oil (VCO) yang dibuat pada Metode Pemanasan Bertahap sebagai Minyak Goreng dengan Penambahan Wortel (Daucus carrota L.) ABSTRAK Telah dilakukan penelitian untuk mengetahui kualitas VCO yang diolah dengan metode pemanasan dengan adanya penambahan wortel (VCO-wortel) sebagai minyak goreng serta perbandingan kualitasnnya dengan VCO tanpa penambahan wortel (VCO),  minyak sawit komersial dan minyak kelapa komersial. Parameter kualitas yang akan di uji yaitu  kadar air, asam lemak bebas, bobot jenis dan bilangan peroksida. Hasil penelitian menunjukan VCO-wortel dan minyak kelapa komersial mempunyai  kualitas yang lebih baik pada sebelum serta setelah penggorengan pengujian dilakukan terhadap kentang beku sebanyak tiga kali. Hasil diuji statistik dengan Anova. dibandingkan dengan  VCO dan minyak sawit komersial. Walaupun nilai asam lemak (FFA) bebas dan bobot jenis minyak kelapa komersial lebih baik daripada VCO-wortel  namun tidak ada perbedaan yang signifikan sehingga pembuatan VCO  wortel dapat memberi pengaruh yang baik terhadap kualitas VCO sebagai minyak goreng. Kata Kunci : Asam lemak bebas, Bobot jenis dan bilangan peroksida, VCO-Wortel THE QUALITY OF VIRGIN COCONUT OIL ( VCO ) MADE IN GRADUAL HEATING METHODS AS THE COOKING OIL WITH ADDITION CARROT (Daucus Carrota L.) ABSTRACT Research has been conducted to determine the quality of the VCO is processed by heating method with the addition of carrots ( VCO - carrots ) as well as comparison kualitasnnya cooking oil with VCO without the addition of carrots ( VCO ) , a commercial palm oil and coconut oil commercial. Quality parameters will be tested the moisture content , free fatty acid , peroxide type and weight. The results showed VCO - commercial carrot and coconut oil has a better quality before and after frying tests conducted on frozen potatoes three times . Results were tested statistically by Anova. compared with VCO and commercial palm oil . Although the value of fatty acids ( FFA ) and free weights commercial coconut oils are better than VCO - carrots but no significant difference thus making carrot VCO can give a good effect on the quality of the VCO as a cooking oil . Keywords : Free fatty acids,  Weight and type of peroxide, VCO-Carrots

The data revealed that based on the property of quality, the best product was bakasang produced using salt 20-30% at 70°C which was fermented for 15 days.
