Jatropha curcas Linn. capsule husk (DH-JcL) is a residu from the manufacture of Crude Jatropha Oil. Biorefinery as part of the "four R's" was required in DH-JcL for anaerobic digestion feedstock. Analysis result and literature study was concluded that DH-JcL is a material that can be managed as biogas substrate, though the nutrient levels relatively low, and a number of other material such as volatile solid, carbohydrates, cellulose ad lignin was relatively high. The establishment of DH-JcL required two phase digestion as anaerobic microbial pretreatment and pre-acidification. The efficiency of two-phase digestion was able to increase the number of technology i.e. additives; recycling of slurry; variation in operational parameters and fixed film or biofilters utilization © 2015 PG Adinurani, RS Hendroko, A Nindita, SK Wahono, M Maizirwan, A Sasmito, YA Nugroho, T Liwang.Published by Elsevier Ltd.

<p>ABSTRACT</p><p>This research was aimed to obtain information on the performance of the five local tomato genotypes and to study the effect of side shoot pruning on the production and fruit quality. The research was started from January to May 2014 in Leuwikopo Teaching Farm and Post Harvest Laboratory IPB using Randomize Complete Block Design with two factors and three replications. The first factor was genotype consisting of five different genotypes i.e Aceh 5, Kudamati 1, Lombok 1, Makassar 3, and Situbondo GL. The second factor was side shoot prunning consisting of two different treatments i.e without side shoot pruning and side shoot pruning. Kudamati 1 has high yield potential, Situbondo GL has earlier flowering and harvesting and also resistant to wilt disease. Lombok 1 has good fruit quality. Plants without side shoot pruning treatment has high yield potential, and has medium-susceptible resistance to wilt disease. Leaf type, attitude of leaflets in relation to main axis, fruit shape fruit cross-sectional, end of the shaft depression, fruit-tip shape, predominant number of locules, and green shoulder indicating diversity.</p><p>Keyword: tomato, pruning, yield, fruit quality</p><p> </p><p>ABSTRAK</p><p>Penelitian ini bertujuan memperoleh informasi keragaan lima genotipe tomat lokal dan mempelajari pengaruh pemangkasan tunas air terhadap produksi dan kualitas buah.

Faktor pertama adalah genotipe yang terdiri atas 5 taraf yaitu Aceh 5, Kudamati 1, Lombok 1, Makasar 3, dan Situbondo GL. Faktor kedua adalah pemangkasan tunas air yang terdiri atas dua taraf yaitu tidak dipangkas dan dipangkas. Kudamati 1 memiliki potensi hasil tinggi, Situbondo GL memiliki umur berbunga lebih awal, umur panen lebih awal (genjah) dan tahan terhadap penyakit layu. Lombok 1 memiliki kualitas buah yang baik. Tanaman dengan perlakuan tanpa pemangkasan tunas air memiliki potensi hasil lebih tinggi dan memiliki ketahanan medium rentan terhadap penyakit layu.

<em>Improvement of rice panicle architecture is one important objective in the development of improved new-plant-type rice varieties. Panicle architecture is directly related to yield components in rice. The aims of this study were to obtain information on inheritance pattern of panicle architecture on F2 generation and to obtain the best selected individuals. The experiment was conducted at Sawah Baru Experimental Farm Bogor, from May to October 2016. Two F2 populations derived from crosses of IPB 3S/IPB160-F-36, IPB160-F-36/IPB 5R and three genotypes of parents were used as experimental materials. A total of 208 and 204 plant samples were taken representing each of the two F2 populations and 20 plants representing the parents. Three panicles were taken randomly from each individual as observed samples. The results showed that additive gene action influenced number of primary branches in population of IPB 3S/IPB160-F-36, whereas in the population of IPB160-F-36/IPB 5R, most of the panicle architecture traits were controlled by additive gene action except for the length of primary branches. All of panicle architecture traits were controlled by relatively many genes except length of primary branches and number of grains on primary branches in the IPB 3S/IPB160-F-36 population. The panicle architecture of the two observed population was genetically varies. The heritability estimates were moderate to high. Selection could increase the mean of panicle architecture traits using either single or multiple traits simultaneously.<br /><br />Keywords: gene action, heritability, genetic variability, panicle traits <br /><br /></em>
Abstract. The possibility of sustainable use of sorghum as raw material for bioethanol needs to be supported by evaluation and selection of sorghum varieties for high biomass production and sugar content. An experiment was conducted on forest dry land , altitude 63 m asl. This research aimed to determine the interaction of sorghum varieties and mycorrhiza on biomass production and the high sugar content. The experiment was a two factor (varieties and dosage of mycorrhiza plus) in a randomized complete block design with three replications. The varieties were Suri 3, Kawali, Super 2, Suri 4. Dosage of mycorrhiza plus (5, 10, 15) g per plant. The interaction only significant on a number of internodes and bagasse. There are no effects of dosages mycorrhiza plus, however, varieties of sorghum have significant effects on many variables measured.
