Abstract

ABSTRACT Aromatherapy candles is the alternative application of aromatherapy by inhalation, i.e inhalation of aroma produced by several drops of essential oils. Aromatherapy candles when burnt produce scent that has theurapeutic effect. The objective of this research was to study the effectivity of nutmeg fruit flesh essential oils with different concentrations (1%, 2%, and 3%) to consumer’s preference on aromatherapy candles (wick position, preference on colour, texture, aroma of the candles both before and after burning). Consumer’s preferences were determined by organoleptic test on 20 untrained panellists. The results showed that the higher concentration of the nutmeg fruit flesh essential oils up to 2%. The higher is the preference on the aromatherapy candles. Nutmeg fruit flesh essential oils are classified as hard in aromatherapy therefore with the concentration of 3% the panelist’s preference on aromatherapy candles decreased due to its very strong aroma. Keywords: Aromatherapy candles, flesh of nutmeg fruit, consumer’s preference, essential oil. ABSTRAK Lilin aromaterapi adalah alternatif aplikasi aromaterapi secara inhalasi (penghirupan), yaitu penghirupan uap aroma yang dihasilkan dari beberapa tetes minyak atsiri. Lilin aromaterapi akan menghasilkan aroma yang memberikan efek terapi bila dibakar. Tujuan dari penelitian ini adalah untuk mempelajari efektifitas minyak atsiri daging buah pala pada beberapa konsentrasi (1%, 2%, dan 3%) terhadap kesukaan konsumen pada produk lilin aromaterapi yang dihasilkan (letak titik sumbu, kesukaan terhadap warna, tekstur, aroma lilin sebelum dan setelah dibakar). Penentuan kesukaan konsumen menggunakan uji organoleptik dengan 20 panelis tidak terlatih. Hasil penelitian menunjukkan bahwa semakin tinggi konsentrasi minyak atsiri daging buah pala sampai konsentrasi 2% menyebabkan kesukaan panelis terhadap lilin aromaterapi semakin tinggi. Minyak atsiri daging buah pala tergolong minyak hardly (keras) dalam aromaterapi, sehingga pada konsentrasi 3% menurunkan kesukaan panelis terhadap lilin karena aromanya sangat kuat. Kata Kunci: Lilin aromaterapi, daging buah pala, kesukaan konsumen, minyak atsiri.

Abstract

ABSTRACTUtilization of nutmeg flesh is still limited; thus, processing it into nutmeg-sheet jam is aimed to improve its added value. However, nutmeg flesh has astringent and bitter taste caused by the tannin level which may impact the processed products. To overcome this problem, a combination of nutmeg flesh and dragon fruit was carried out. The purpose of this study was to determine the exact proportion of nutmeg and dragon fruit juice to produce a nutmeg-sheet jam that is preferred by consumers. This study used a one-factor Randomized Complete Design, namely the proportion of nutmeg flesh juice and dragon fruit juice consisting of three treatment levels, namely: P1 (100%:0%), P2 (75%:25%), P3 (50%:50 %). The organoleptic testing on nutmeg-sheet jam products used the hedonic test conducted by 30 semi-trained panelists. The results show that different ratios of nutmeg flesh juice and dragon fruit juice significantly influence the consumers’ preference for color, appearance, taste, aroma, texture, and overall acceptance. The nutmeg-sheet jam with a proportion of 75% nutmeg juice and 25% of dragon juice was the most preferred product by the consumers. The selected product has 28.72 mg vitamin C /100 g of ingredients and pH 4.2.Keywords: nutmeg flesh, dragon fruit, nutmeg-sheet jam, consumers’ preferenceABSTRAKPemanfaatan daging buah pala masih terbatas, sehingga pengolahan daging buah pala menjadi selai lembaran merupakan usaha untuk meningkatkan nilai guna. Namun, daging buah pala memiliki rasa sepat dan rasa getir yang disebabkan oleh adanya kadar tannin yang akan berdampak pada produk olahannya. Untuk mengatasi permasalahan ini, maka dilakukan kombinasikan daging buah pala dengan buah naga. Tujuan penelitian ini adalah menentukan proporsi sari buah pala dan sari buah naga yang tepat yang dapat menghasilkan selai lembaran yang disukai oleh konsumen. Penelitian ini menggunakan Rancangan Acak Lengkap satu faktor, yaitu proporsi sari buah pala dan sari buah naga yang terdiri dari tiga taraf perlakuan yaitu: P1 (100%:0%), P2 (75%:25%), P3 (50%:50%). Pengujian organoleptik terhadap produk selai lembaran menggunakan uji hedonik oleh 30 panelis. Hasil penelitian menunjukkan bahwa rasio sari buah pala dan sari buah naga yang berbeda memberi pengaruh nyata terhadap tingkat kesukaan konsumen pada atribut warna/kenampakan, rasa, aroma, tekstur dan penerimaan keseluruhan (over all). Selai lembaran dengan penambahan rasio sari buah pala 75% dan sari buah naga 25 % merupakan produk yang paling disukai oleh konsumen dengan kandungan vitamin C 28.72 mg/100 g bahan dan pH 4.2.Kata kunci : daging buah pala, buah naga, selai lembaran, preferensi konsumen

Abstract

Morphological identification and population of fruit fly (Bactrocera sp.) (Diptera: Tephritidae) in chili fields, SavanajayaVillage Buru District. Fruit fly (Bactrocera sp.) are pests that damage horticultural crops, one of which is chili and has thepotential to reduce the production quality and quantity. The aim of this research was to identify and obtain populationnumbers of fruit fly species in the chili fields in Savanajaya Village, Buru District. This study used diagonal sampling methodwith fruit fly traps placed randomly at each sub location of sampling, traps were modified Steiner ’s Trap type. Each trap wasconsisted of 1.5 mL of methyl eugenol on cotton ball, the treatment was repeated three times. Observations were at 3, 6, 9 and12 days after application (daa). The identification results showed that the fruit flies species that trapped were Bactroceradorsalis (Hendel) and Bactrocera umbrosus (Fabricius). The highest number of fruit fly was trapped at 6 daa with an averageof 110.67 to 134.03 or 48.51 to 58.73% from total catch, in addition the lowest catch was at 12 daa with an average of 29.67 to64.67 or 12.99 to 28. 34%. The average number of trapped population was 914.62 individuals.
