Most of cassava grown in Palas, South Lampung District is sweet type cassava (Manihot esculenta Crantz) utilized as raw materials for cassava-based snack production. However, their characteristic had never been reported. The aims of the research were to determine the effect of varieties, harvesting age, and interaction between varieties and the harvesting age on morphology and chemical characteristics of sweet type cassava planted in Palas District, South Lampung. The experiment was factorial and arranged in a Complete Randomized Block Design (CRBD) with two factors and four replications. The first factor was cassava variety, i.e., manalagi (V1), mentega (V2), and krembi (V3). The second factor was the harvest age (U) i.e., 7-8 months (U1) and 8-9 months (U2). Morphology data were reported descriptively, while data for other characteristics were tested for homogeneity and additivity using Barlett and Tuckey test, then subjected to ANOVA, and further tested using Duncan test at the level of 5%. The results showed that the variety and harvest age significantly affected of water content, starch yield, starch content, amylose, and amylopectin. There was a significant interaction between varieties and age of harvest on moisture content, starch yield, and starch content, but there was no significant interaction effect on amylose and amylopectin. The highest value of moisture content was found in manalagi aged at 7-8 months (67.28% wb), the highest value of starch yield was found in manalagi age at 8-9 months of (16.34%), the highest value of starch content was found in mentega aged at 8-9 of months (17.52 % wb), the highest value of amylose was found in mentega aged at 8-9 of month (10.35% db), the highest value of amylopectin was found in krembi aged at 7-8 of month (92.78% db). Overall, krembi, manalagi, and mentega can be categorized as low-amylose cassava which has potential to be developed as raw material for crispy cassava-based snack. Keywords: harvesting age, krembi, low-amylose cassava, manalagi, mentega

<p>Buah biwa (Eriobotrya japonica) sangat baik untuk kesehatan tubuh dan dapaat digunakan sebagai bahan baku obat-obatan. Budidaya tanaman biwa di tingkat petani saat ini masih bersifat tradisional, sehingga produksinya masih rendah dan belum dapat memenuhi kebutuhan konsumen. Salah satu penyebabnya ialah keterbatasan informasi mengenai penggunaan pupuk yang efektif dan efisien pada pembudidayaannya. Penelitian bertujuan mengetahui pengaruh pemberian pupuk N, P, dan K pada tanaman biwa. Penelitian dilakukan di Kebun Percobaan Tanaman Buah Berastagi dengan ketinggian tempat 1.340 m dpl., dengan jenis tanah Andisol, yang dilaksanakan dari bulan Januari sampai dengan Desember 2006. Percobaan menggunakan rancangan  acak kelompok pola faktorial dengan dua ulangan. Perlakuan terdiri atas tiga faktor yakni : N (0, 180, dan 360 kg/ha), P (0 dan 36 kg/ha), dan K (0, 180, dan 360 kg/ha). Hasil penelitian menunjukkan adanya  interaksi NxP dan NxK terhadap pertambahan tinggi tanaman pada umur 6 dan 8 bulan setelah pemberian pupuk pertama.Tidak ada interaksi NxP yang nyata terhadap pertambahan diameter batang, namun ada interaksi NxK yang nyata terhadap pertambahan diameter batang pada umur 4, 6, dan 8 bulan setelah pemberian pupuk pertama. Taraf dosis pupuk N:P:K (360:36:180) kg/ha menghasilkan pertumbuhan vegetatif tanaman biwa (tinggi tanaman, diameter batang, serta jumlah tunas) yang lebih baik dari perlakuan lainnya. Hasil analisis daun biwa memperlihatkan bahwa kandungan hara N, P, dan K   terbesar dalam daun yang ditemukan pada perlakuan dosis pupuk N:P:K (360:36:180) kg/ha. Implikasi dari penelitian ini adalah sebagai pedoman pemupukan pada budidaya biwa.</p><p> </p><p>Loquat fruits is very good for human health. Furthermore, it can be used as the raw material for some medicines. Until now the loquat cultivataion is still traditionally practiced by farmers, so its production is still very low and can not fulfill consumers demand. One of the reasons is that the information of effective and efficient fertilization is not available. The objective of the research was to determine the effect of  N, P, and K fertilizers on the growth of loquat. The research was conducted at Berastagi Experimental Fruit Farm, at altitude of 1,340 m asl, with  Andisol soil type, on January to December 2006. A randomized block design was used with two replications. The research consisted of 18 treatments combination with three factors i.e. N (0, 180, and 360 kg/ha), P (0 and 36 kg/ha), and K (0, 180, and 360 kg/ha). The results showed that there were significant interaction effects of NxP and NxK to plant height on 6 and 8 months after the first fertilizer application. The significant interaction effect of NxK was also stem diameter on 4, 6, and 8 months after the first fertilizer application. The  dosage of N:P:K (360:36:180 kg/ha) exhibited better vegetative growth of loquat (plants height, stem diameter, and number of shoots) compared to other treatments. The analysis of loquat leaves indicaated that the content of N, P, and K nutrients on leaves was higher on the fertilizer dosage of N:P:K = 360:36:180 kg/ha  compared to the other fertilizer treatments.Implication of the research is to guide fertilizing on loquat cultivation.</p>

Abstract.Currently ethanol produced from molasses, cassava and maize, thereby competing with the need for food, animals feed and other industrial raw materials, so that the supply of raw materials is not continuity. If this continues, it will certainly have an impact on food prices spike, it will create new problems on the economy of the community, and one of an alternative raw material for bioethanol production is cellulose biomass.To convert biomass into bioethanol through several stages, including pretreatment, hydrolysis and fermentation. The content of lignin in biomass will disturb the enzymatic hydrolysis process, so it is necessary to encourage the delignification in the pretreatment stage. Microwave - alkali pretreatment can reduce more lignin and hemicellulose in rice straw, so it needs to be an effort to change the composition of lignocellulose and improve the hydrolysis of corn cob is fermented to become ethanol. Pretreatment of corn cobs research was done using randomized block design arranged in factorial and repeated 2 times. The first factor is the concentration of NaOH for 0,5 N, 1 N and 1,5N. The second factor is the time of exposure to microwave heat radiation for 10, 20 and 30 minutes. The results showed that cellulose content increases with prolonged exposure concentrations of NaOH and microwave, as well as to the content of hemicellulose and lignin decreased along with the increase of exposure duration of Microwave and the increase of NaOH concentrations.
