Judul: Effect of Storage Temperature and Soaking in Methyl Jasmonate on Fruit Quality of Kecapi Fruit (Sandoricum koetjape (Burm. f.) Merr.)
Abstrak: Buah kecapi (Sandoricum koetjape (Burm. f.) Merr.) masih melakukan aktivitas metabolisme setelah dipanen karena termasuk buah klimaterik. Penyimpanan suhu dingin dapat mengurangi aktivitas metabolisme, namun kecapi termasuk salah satu buah yang sensitif terhadap suhu dan akan mengalami gejala chilling injury saat disimpan di suhu rendah yang tidak tepat. Penelitian ini bertujuan mengetahui suhu simpan dan lama perendaman methyl jasmonate yang sesuai untuk menjaga kualitas buah kecapi selama masa penyimpanan. Penelitian ini menggunakan rancangan acak lengkap dua faktor yaitu suhu simpan (27,94 °C dan 3,03 °C) dan lama perendaman dalam 0,1 mM methyl jasmonate (10 menit dan 30 menit). Hasil penelitian menunjukkan gejala chilling injury sudah terlihat di minggu pertama penyimpanan baik di perlakuan kontrol maupun di buah yang sudah diberi perlakuan methyl jasmonate. Buah yang disimpan di suhu dingin dan diberi perlakuan perendaman methyl jasmonate memiliki kualitas fisik buah lebih baik dibanding perlakuan lainnya. Nilai rata-rata peningkatan susut bobot pada perlakuan tersebut sebesar 11,48% dan 11,80% selama masa penyimpanan., Kecapi fruit (Sandoricum koetjape (Burm. f.) Merr.) still carries out metabolic activity after being harvested because it is a climacteric fruit. Cold storage can reduce metabolic activity, but kecapi is one of the fruits that is sensitive to temperature and will experience chilling injury symptoms when stored at inappropriately low temperatures. This study aims to determine the appropriate storage temperature and soaking time for methyl jasmonate to maintain the quality of kecapi fruit during the storage period. This study used a completely randomized design with two factors, storage temperature (27,94 °C and 3,03 °C) and soaking duration in 0,1 mM methyl jasmonate (10 minutes and 30 minutes). The results showed that chilling injury symptoms were visible in the first week of storage, both in the control treatment and fruit that had been treated with methyl jasmonate. Fruit stored at cold temperatures and soaked in methyl jasmonate had better physical fruit qualities than other treatments. The average value of the increase in weight loss in these treatments was 11,48% and 11,80% during the storage period.

Judul: Effects of Differences in Storage Temperature and Concentration of Methyl Jasmonate on the Quality of Kecapi Fruit (Sandoricum koetjape (Burm.f.) Merr.)
Abstrak: Kecapi atau santol merupakan buah tropis yang memiliki banyak manfaat namun saat ini sudah jarang ditemui keberadaannya. Buah kecapi memiliki masa simpan hingga 7 hari pada suhu ruang. Perlakuan pascapanen untuk memperpanjang masa simpan yaitu dengan penyimpanan suhu dingin dan aplikasi metil jasmonat untuk mengurangi chilling injury. Penelitian ini bertujuan untuk mendapatkan suhu simpan dan konsentrasi metil jasmonat yang sesuai terhadap masa simpan dan kualitas buah kecapi. Penelitian ini menggunakan rancangan acak lengkap (RAL) faktorial, dengan dua faktor yaitu suhu simpan yang terdiri atas suhu dingin (11-12 °C) dan suhu ruang (28 °C). Faktor kedua berupa konsentrasi metil jasmonat yang terdiri atas kontrol (0 mM), 0,1 mM dan 1 mM. Hasil penelitian menunjukkan bahwa kombinasi antara perlakuan suhu dingin dengan konsentrasi 0,1 mM metil jasmonat memiliki hasil terbaik dalam menjaga kualitas fisik (bobot buah, diameter, panjang dan kekerasan buah) dan kualitas kimia (PTT dan ATT), serta dapat memperpanjang masa simpan hingga 1 minggu penyimpanan., Kecapi or santol is a tropical fruit that has many benefits, but nowadays it is rarely found. The kecapi fruit has a shelf life of up to 7 days at room temperature. Postharvest treatments to extend the shelf life is to use cold storage and application of methyl jasmonate to reduce chilling injury. This research aimed to obtain the appropriate storage temperature and concentration of methyl jasmonate for the shelf life and quality of the kecapi fruit. The experiment used a factorial completely randomized design (CRD), with two factors namely storage temperature which consists of cold temperature (11-12 °C) and room temperature (28 °C). The second factor is the concentration of methyl jasmonate which consists of control (0 mM), 0,1 mM and 1 mM. The results showed that the combination of cold temperature treatment with a concentration of 0,1 mM methyl jasmonate had the best results in maintaining physical quality (fruit weight, diameter, length and fruit hardness) and chemical quality (PTT and ATT), and can extend the self life up to 1 week of storage.

Judul: Query Expansion based on Bilingual Dictionary Using Conditional Probability
Abstrak: Query expansion is a technique that can be used to bridge vocabulary gaps between queries and documents in the collection. With query expansion, user will be helped to formulate queries well so that user will optimize the search result. In this study, the expansion term was resulted from the translation of bilingual dictionary. Subsequently, several terms of expansion were elected based on the closeness of its relationship with the original query. This research showed that conditional probability can be used to select expansion term in bilingual translation method query expansion. The result of 1000 documents was more than 97% relevan document can be retrieved by this system. The more expansion term used, the larger number relevan document was retrieved.
