One of the major constraints in chili production system in Indonesia is the fruit fly attack on chili fruits. These pests often lead to crop failure if not treated seriously. One way used to suppress the pest population is the use of Methyl Eugenol attractant compound (Petrogenol 800 L). The study was conducted to determine the effect of methyl eugenol dose and catching time difference on fruit flies that were caught. The study took place in Waimital Village, Kairatu Subdistrict, West Seram District. The research was conducted in an experiment using a Randomized Block Design (RAB) with 5 treatments, namely: (A) 0.5 ml of methyl eugenol, (B) 1 ml of methyl eugenol, (C) 1.5 ml of methyl eugenol, (D) 2 ml methyl eugenol, (E) 2.5 ml of methyl eugenol, placed in a each trap. Observations were conducted when the insects were active at 10.00 (06.00-10,00 period) and when the insects were inactive at 18:00 hours (11:00 to 18:00 period) on the number of fruit fly imagoes that were captured. The results showed that the effective methyl eugenol dose to catch Bactrocera dorsalis was in treatment C (1.5 ml, with 32.53 fruit flies caught per day or 97.67 fruit flies catches during three days of observation. The highest number of catch for 3 days was at 2,5 ml, with 118.60 fruit flies caught.

Utilization 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

Fruit flies (Diptera: Tephritidae) are important pests of horticultural crops with the intensity of their attacks can achieve 100%.  The control by quarantine regulations and the use of attractants will be more successful when the information about the species that attack horticultural crops has been known clearly. This study aimed to identify the species of fruit fly that attack pepper (Capsicum annum), bitter melon, guava and guava bol and to know the number and sex ratio of fruit fly pests. The method used was the survey methods, by taking/collecting pepper, bitter melon, guava and guava bol which contained fruit fly attack symptoms, maintained until it was discovered in the imago, later it was identified. Based on the results of the study, we found that fruit flies that attack the chili was B. papaya, in bitter melon was B. cucurbitae, in bool guava fruit and guava was B. Albistrigata. The number of fruit flies in chili was 21, in bitter melon was176, 89 in bol guava, and in guava was 90. Sex ratio in chili fruit flies (1:1), bitter melon (1:1), guava bol (1:1) and guava (2:1).

One of the obstacles in efforts to increase rice productivity is the damage caused by the attack of the rice stem borer. Annual yield loss caused this insect pests is quite high, reaching 10-30%. The attack of stem borer has long been encountered and is a problem in rice producing areas on Buru Island, such as in Savanajaya Village. This study aimed to obtain data on the types of pests, population levels and the intensity of damage in five rice varieties due to stem borer attact and to determine the varieties that had the lowest population and damage intensity in the Saavanajaya Village, Waeapo District, Buru Regency. The method used was a survey method that focused on five varieties of rice cultivated by farmers, to obtain population data and the intensity of damage. The results showed that the type of pest that attacked the five rice varieties of IR-64 variety in Savanajaya Village was the white rice stem borer (Scirpophaga innotata), with the highest larval population (per cluster) of 1.27 individuals and the intensity of damage 5.20%, followed by Cigeulis variety with a larval population of 1.17 individuals and damage intensity of 4.70%, the Ciherang variety with a larval population of 1.07 individuals and damage intensity of was 4.25%, the Mekongan variety with a larval population of 1.1 individuals and damage intensity of 4.15%, and the lowest was the Membramo variety with a larval population of 1.03 larvae and damage intensity of 4.12%. The damage intensity of at the study site, although different between varieties, could all be classified into the category of mild attack.

Kehilangan hasil setiap tahun yang disebabkan oleh serangga hama ini padi cukup tinggi, bisa mencapai 10-30%. Serangan hama penggerek batang telah lama ditemui dan menjadi masalah di daerah produsen padi di Pulau Buru, seperti di Desa Savanajaya. Penelitian ini bertujuan untuk mendapatkan data jenis hama, jumlah populasi serta intensitas kerusakan pada lima varietas padi akibat serangan hama penggerek batang serta menentukan varietas yang memiliki populasi dan intensitas kerusakan terendah di Desa Savanajaya, Kecamatan Waeapo, Kabupaten Buru. Metode yang digunakan adalah survey yang difokuskan pada lima varietas padi yang diusahakan petani, untuk mendapatkan data populasi dan ntensitas kerusakan. Hasil penelitian menunjukkan bahwa jenis hama yang menyerang lima varietas padi varietas IR-64 di Desa Savanajaya adalah penggerek batang padi putih (Scirpophaga innotata), dengan populasi larva (per rumpun) tertinggi 1,27 ekor dan intensitas kerusakan 5.20%, diikuti oleh varietas Cigeulis dengan populasi larva 1,17 ekor dan internsitas kerusakan 4.70%, varietas Ciherang dengan populasi larva 1.07 ekor dan intensitas kerusakan 4.25%, varietas Mekongan dengan populasi larva 1.1 ekor dan intensitas kerusakan 4.15 %, dan yang terendah varietas Membramo dengan populasi larva 1.03 ekor dan intensitas kerusakan 4.12%.

ABSTRAKPengembangan pestisida nabati untuk menekan  populasi hama sudah menjadi salah satu cara yang efektif.  Pemberian bubuk gagang cengkih terhadap pertumbuhan populasi (Callosobruchus chinensis L penting untuk diteliti. Pestisida ini bersifat mudah terurai (biodegradable), sehingga tidak mencemari lingkungan dan relatif aman bagi manusia dan ternak karena residunya mudah hilang. Penelitian ini bertujuan untuk Mendapatkan dosis bubuk gagang cengkih (Syzygium aromaticum) yang efektif untuk mengendalikan kumbang (Callosobruchus chinensis L.) dalam simpanan kacang hijau. Penelitian ini menggunakan Rancangan Acak Lengkap dengan dosis bubuk gagang cengkih terdiri dari 5 perlakuan yaitu: kontrol, 10 g, 15 g, 20 g, 25 g.
