Penurunan kualitas selama penyimpanan merupakan permasalahan yang seringkali ditemui pada pascapanen buah jambu kristal. Oleh karena itu, diperlukan penanganan yang tepat. Penanganan pascapanen yang umum digunakan adalah dengan penggunaan kemasan. Tujuan penelitian ini adalah untuk mengkaji hubungan berbagai kemasan dan masa simpan terhadap nilai kekerasan, total padatan terlarut (TPT) dan kadar air buah jambu kristal. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) pola faktorial dengan 4 ulangan. Faktor pertama adalah pengemasan (tanpa kemasan (kontrol), plastik wrapping, koran) dan faktor kedua adalah masa simpan (0, 4 dan 8 hari). Data yang diperoleh kemudian diolah dengan analisis sidik ragam (ANOVA), selanjutnya diuji Duncan dengan taraf 5%. Hasil yang didapatkan menunjukkan tidak terjadi interaksi antara jenis kemasan dan masa simpan terhadap nilai kekerasan, TPT dan kadar air buah jambu kristal. Namun, jenis kemasan koran menampilkan nilai kekerasan buah jambu kristal yang lebih rendah daripada perlakuan tanpa kemasan (kontrol) dan plastik wrapping, sedangkan masa simpan 0 hari memperlihatkan nilai kekerasan buah jambu kristal yang lebih tinggi dibandingkan dengan masa simpan 4 dan 8 hari. Nilai kekerasan buah mengalami penurunan setelah 4 hari penyimpanan. Penggunaan kemasan berupa plastik wrapping dan koran tidak lebih baik dibandingkan dengan tanpa pengemasan (kontrol) terhadap nilai kekerasan pada buah jambu kristal.ABSTRACT Losses during storage is often encountered in postharvest of crystal guava fruit. Therefore, proper handling is needed. Packaging is the most commonly performed postharvest handling. The purpose of this study was to examine the relationship of various packagings and storage periods to the values of firmness, total soluble solids (TSS) and water content of crystal guava fruit. This study used factorial arrangement of completely randomized design (CRD) with four replications. The first factor was packagings (without packaging (control), wrap plastic and paper) and the second factor was storage periods (0, 4, and 8 days) in room temperature (±250C). The data obtained then processed using analysis of variance (ANOVA), then duncan test was carried out with a level of 5%. The results showed no interaction between the types of packaging and storage periods to the values of firmness, TSS and water content of crystal guava fruit. However, the paper packaging presented the firmness value which was lower than without packaging (control) and wrap plastic, whereas the 0 day storage showed the firmness value fruit which was higher than the 4 and 8 days storage. Value of fruit firmness decreased after 4 days of storage. The use of packaging in the form of wrap plastic and paper were not better than without packaging (control) to the firmness of the crystal guava fruit.

Luas perkebunan kelapa sawit di Indonesia pada tahun 2014 mencapai 10 juta Ha. Pertumbuhan yang pesat diikuti dengan produksi crude palm oil (CPO) dan palm karnel oil (PKO) yang juga meningkat, sekaligus produk sampingan berupa limbah. Salah satu limbah pabrik kelapa sawit yang jumlahnya besar adalah tandan kosong kelapa sawit (TKKS). Tandan kosong kelapa sawit merupakan limbah organik yang berpotensi dimanfaatkan dibidang pertanian. Akan tetapi, TKKS memiliki nilai C/N yang cukup tinggi, akibatnya sukar dan lama untuk terdekomposisi. Salah satu cara pemanfaatan TKKS adalah dengan dilakukan pengomposan dengan pengkayaan urea. Diharapkan dengan perlakuan tersebut TKKS akan cepat terdekomposisi dan dapat segera dimanfaatkan oleh tanaman. Penelitian ini bertujuan untuk (1) mengetahui pengaruh pemberian urea terhadap pengomposan TKKS dan (2) mengetahui pengaruh peningkatan dosis urea terhadap kualitas kompos TKKS. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) faktor tunggal dengan 5 perlakuan, yaitu U1 (urea 0 g setara dengan nilai C/N=), U2 (urea 30,9 g setara dengan nilai C/N=), U3 (urea 79,3 g setara dengan nilai C/N=), U4 (urea 176,1 g setara dengan nilai C/N=) dan U5 (urea 466,3 g setara dengan C/N = ) dan 9 ulangan, sehingga diperoleh 45 satuan percobaan. Hasil penelitian menunjukan bahwa pemberian urea berpengaruh sangat nyata terhadap susut bobot, kadar air, nilai pH kompos, C-organik, N-total, P-tersedia, dan nilai C/N, selain itu pemberian urea mengakibatkan terjadi perubahan tekstur dan warna pada kompos TKKS. Pemberian dosis urea 466,3 g mampu meningkatkan kandungan N-total, serta menurunkan nilai C/N dan nilai pH kompos. Pemberian dosis urea 79,3 g atau setara dengan C/N = mampu meningkatkan kandungan P-tersedia dan kadar air, menurunkan susut bobot dan kandungan C-organik, serta menunjukan perubahan tekstur dan warna yang lebih baik.

Sugarcane (Saccharum spp. hybrids) is moderately sensitive to salinity and the effects on plant performance vary according to stress level and genotype. This study aimed to evaluate the effect of salt stress induced by application of different NaCl levels in the irrigation solution on plant height, indirect index of chlorophylls (SPAD), and macronutrients concentration (N, P, K, Ca, Mg and S) and Na in leaves of two sugarcane varieties: CP 72-2086 and Mex 69-290. The experiment was set in a completely randomized design with a 2×5 factorial arrangement. The study factors were sugarcane variety (CP 72-2086 and Mex 69-290) and NaCl concentration (0.0, 71.8, 143.6, 215.4 and  282.7 mM NaCl). Salinity as a single factor negatively affected plant height, SPAD units and N and P concentration in leaves; Ca concentrations increased, while K, Mg and S remained unaffected by the tested NaCl levels. Mex 69-290 grew higher and concentrated greater levels of N and K. Interactions of factors showed that salinity reduced growth in both varieties, but this reduction was more pronounced in CP 72-2086. SPAD units were also significantly reduced by salinity in both varieties. Concentrations of N and P in leaves decreased in both varieties in response to NaCl, while those of K and Ca increased in Mex 69-290. Concentration of Na was higher in Mex 69-290 which exhibited better performance than CP 72-2086. Sodium concentrations in leaves increased in direct relation to the tested NaCl concentrations. Mex 69-290 reached higher concentrations of Na in leave tissues but displayed better health than CP 72-2086. Thus, the variety Mex 69-290 showed more efficient Na-tolerance mechanisms related to Ca and K concentrations, and an indirect chlorophyll index better than CP 72-2086.

Calla lily is an appreciated specie used for flower arrangements. In spite of its commercial importance, there is little information on calla lily postharvest conservation. Thus, this study aimed to determine the best sucrose concentration for pulsing and cold storage conditions to extend calla lily postharvest durability. Flower stalks were submitted to a pulsing pre-treatment using 2, 4, 8, 12 and 16% sucrose in the solution, for one hour, plus a treatment with direct storage in cold chamber (4ºC), without a prior-treatment. Dry storage or storage in solution with the commercial product Flower® was also tested. A completely randomized design was used with four replicates and three inflorescences per plot. Spathe length and width were daily measured from which the opening and wilting processes were analyzed. It was observed that pulsing with sucrose was efficient in extending calla lily inflorescences opening process and durability. Dry storage for short periods (less than six days) can also be used, but a prior-treatment with 12% sucrose pulsing for one hour or with a water supply for the same period was required. For storage in solution, a pulsing with 5% or 7.5% sucrose was recommended.

<p>‘Maha Chanok’<strong> </strong>mango is an economic fruit crop widely cultivated commercially throughout Thailand. By nature, mango fruit has a rather limited storage life after harvest. 1-methylcyclopropene (1-MCP) has been accepted as a commercial substance to improve several fruit qualities. The objective of this research was to study the effects of 1-MCP on the external postharvest qualities and storage life on the ‘Maha Chanok’ mango fruit. The experiment was laid out in a Completely Randomized Design with three replicates, ten fruits per replicate. Mango fruit was fumigated with 1-MCP at three concentrations (1000, 1250, or 1500 nl l<sup>-1</sup>) and three fumigation periods (12, 18, or 24 h), compared with the control fruit. After treating, all treatments were stored under ambient temperature (27 °C, 80%R.H.). The following determinations were made every two days for assessment of fruit weight loss, firmness, chlorophyll content, decay incidence, and storage life. The results showed that fruit treated with 1500 nl l<sup>-1</sup><strong> </strong>1-MCP for 24 h had the maximal fruit firmness. For chlorophyll content, the results showed that fruit-treated with 1500 nl l<sup>-1</sup><strong> </strong>1-MCP for 12 h could effectively retain the highest chlorophyll contents. Furthermore, both the lowest fruit decay and the longest storage life of 12 days were achieved from the fruit treated with 1000 nl l<sup>-1</sup><strong> </strong>1-MCP for 12 h.</p>
