Abstract

Jambu biji ‘Crystal’ memiliki masa simpan yang singkat dan mudah mengalami kerusakan. Masa simpan buah jambu biji ‘Crystal’ hanya berkisar 2 – 7 hari. Upaya pascapanen yang dapat dilakukan untuk meningkatkan masa simpan adalah denganaplikasi Aminoethoxyvinylglycine (AVG), pengemasan dengan plastic wrapping, dan penyimpanan suhu rendah. Penelitian ini bertujuan untuk mengetahui pengaruh aplikasi AVG, plastic wrapping, suhu simpan, dan interaksi antara aplikasi AVG,plastic wrapping dan suhu simpan terhadap masa simpan dan mutu buah jambu biji ‘Crystal’. Penelitian ini dilaksanakan di Laboratorium Pascapanen Hortikultura, Fakultas Pertanian, Universitas Lampung pada bulan September – Oktober 2014.Penelitian ini menggunakan Rancangan Teracak Sempurna (RTS) dengan tiga ulangan. Rancangan penelitian ini disusun secara faktorial 2 x 2 x 2. Faktor pertama adalah AVG (dengan dan tanpa AVG), faktor kedua adalahplastic wrapping(dengandan tanpa plastic wrapping), faktor ketiga adalah suhu simpan (suhu ruang 26,87 °C dan suhu rendah 21,53 °C). Hasil penelitian menunjukkan bahwa aplikasi AVG tidak mampu meningkatkan masa simpan, kekerasan, susut bobot, °Brix, asam bebas, dan kemanisan pada buah jambu biji ‘Crystal’. Aplikasi plastic wrapping mampu menekan susut bobot, tetapi tidak mampu meningkatkan masa simpan, mempertahankan kekerasan, °Brix, asam bebas, dan tingkat kemanisan buah jambu biji ‘Crystal’. Penyimpanan suhu rendah tidak mampu meningkatkan masa simpan, kekerasan, susut bobot, °Brix, asam bebas, dan kemanisan pada buah jambu biji ‘Crystal’ dan tidak terdapat interaksi antara AVG, plastic wrapping dan suhu rendah dalam meningkatkan masa simpan dan mempertahankan kekerasan, susut bobot, °Brix, asam bebas, dan kemanisan pada buah jambu biji ‘Crystal’.

Abstract

Guava ‘Crystal’ is one of the leading export product of guava. Postharvest problem that occur on guava ‘Crystal’ is the rapid process of ripening and the development of brown spots, so the shelf-life is shorter and causes a decrease in fruit qualities. Damage to fruit can be solved by soaking the fruit in a solution or by coating the fruit, so the rate of respiration and transpiration can be slowed. The material used for soaking the fruit was a plant growth regulators of benziladenine (BA). This research was aimmed at (1) studying the effects of the addition of BA into chitosan coating on the quality and shelf-life of guava ‘Crystal’, and (2) obtaining the best concentration of BA added to the chitosan coating to maintain the quality and prolong the shelf-life of guava ‘Crystal’. The results showed that (1) the addition of 2.5% chitosan coating was significantly able to prolong the fruit shelf-life of guava ‘Crystal’ of 2.83 and 6.12 days longer than control and acetic acid 0.5%, (2) the addition of BA concentrations of 25, 50 and 100 ppm shortened significantly the fruit shelf-life of guava ‘Crystal’, but did not influence its qualities, and (3) the using of 0.5% acetic acid as a solvent in 2.5% chitosan did not cause a bad affect, but soaking in 0.5% acetic acid as a main solution adversely affected the fruit qualities and shelf-life of guava ‘Crystal’.

Abstract

One of the common problems that can be easily found in educational institutions in general, and Islamic boarding schools in particular, is the poor handling of organic and inorganic waste. If waste is handled correctly, it will not only minimize environmental pollution but can also be a source of fundraising. Ulul Albab Islamic Boarding School (UA IBS), which is located in the village of Banjaragung, dist. Jatiagung, reg. South Lampung, Lampung province, Indonesia, was the target partner in organic and inorganic waste management assistance activities. This initial assistance activity, in the form of counseling, was the initial part of the Assistance Program for Organic and Inorganic Waste Management at UA IBS. The main objective of this extension activity was to increase the knowledge of UA IBS managers and residents about integrated organic and inorganic waste management. The method of carrying out this activity was a face-to-face discussion on the concept and technique of integrated waste management to produce a value-added product in the form of compost. The results of this counseling activity were evident from the response of the manager, asatidzah, and students who enthusiastically participated in the activity and increased their knowledge about integrated organic and inorganic waste management to become value-added products.

Abstract

Button mushrooms (Agaricus bisporus) have become an attractive agricultural product due to their high nutritional value and use as food. However, since it has a low shelf life, further storage condition needs to be studied. This research investigated the quality changes of button mushrooms under different storage conditions. The mushrooms were stored both in cold and room temperature. The treatments used are different packaging materials such as Styrofoam, polyethylene, and edible coating, where the unpacked mushroom is used as control. Observed parameters are sensory, water content, and weight loss. Button mushrooms with edible coating at cold and room temperature storage were determined as the best treatment that resulted in the lowest decrease in weight loss and water content. Based on this study, the recommended storage condition for button mushrooms is using edible coating in cold temperatures.
