Bu çalışmada mısır silajına katkı maddesi olarak yemlik keçiboynuzu kırığı kullanılmıştır. Oluşan silajların besin madde kompozisyonu, fermantasyon parametreleri ve in vitro fermantasyon değerleri ve aerobik stabilitesi incelenmiştir. Oluşan silajların kuru madde içerikleri % 23,66 ile 25,73 arasında bulunmuştur. Ham kül içerikleri % 11,01 ile 14,77 ve ham protein içerikleri % 7,29-8,09 arasında bulunmuştur. Silajların ADF ve NDF içerikleri sırasıyla % 12,97-14,82 ve 23,74-26,87 tespit edilmiştir. Silajların pH’ları 3,61 ila 3,80 arasında bulunmuş ve olması gereken pH değerlerinden düşük bulunmuştur. Katkı dozlarına bağlı olarak silajların fleig skorları 87,47 ile 93,46 arasında hesaplanmıştır. Silajların in vitro fermantasyon parametreleri incelendiğinde net gaz üretimleri 34,62 ila 36,2 ml arasında değişmiş olup metan üretim yüzdeleri 16,90-17,87 arasında değişmiştir. Katkı dozunun artması ile oluşan silajların Metabolik Enerji içerikleri 7,68 den 8,36 yükselmiştir. Katkı dozunun artması ile içermiş olduğu şeker oranı ile doğrudan alakalı olarak aerobik stabiliteleri öne çekilmiş yani kontrol grubuna göre daha erken bozulduğu görülmüştür.

Soybean is an important crop not only in African countries, but also in the entire world being one of the most protein containing legume from its seeds which is used as food among other uses of the crop such as Nitrogen fixation. However, in Africa, low production levels have been recorded over the years with Africa contributing to 1% of the entire world soybean production. This paper therefore sought to determine the yield production for soybean varieties under different spacing on maize intercrop. The paper adopted experimental research design. From the analysis results on the measure of the total yield production for soybean varieties on different spacings on maize intercrop, the study established that DPSB variety seeds had the highest average weight while Gazelle and Nyala variety had the least average weight of seeds. The researcher recommended DPSB19 variety at 30cm with an average of 14.10335g with only the research boundary factors maintained on the total yield production for soybean varieties on different spacing on maize intercrop.

Fertilizer divided becomes two, namely fertilizer organic and inorganic. According to USEPA, fertilizer organic is applied compost to plants as source nutrients. Fertilizer inorganic is fertilizer result of engineering process by chemical, physical and or biological and the results industry or factory maker fertilizer (Dewanto et al., 2013). Plant need fertilizer to reach production maximum. In research Roidah (2013) there is several of types of fertilizer the observed organic fertilizer cage contains 5 kg N, 3 kg P 2 O 5 and 5 kg K 2 O as well as other essential nutrients in relative amount small.

肥料分为两种，即有机肥和无机肥。根据美国环保署的说法，有机肥料是将堆肥作为植物的营养来源。无机肥料是通过化学、物理和(或)生物工程过程和工业或工厂制造肥料的结果的肥料(Dewanto et al.， 2013)。植物需要施肥才能达到最大产量。在Roidah(2013)的研究中，有几种类型的肥料，观察到有机肥笼含有5 kg N, 3 kg p2o和5 kg k2o以及其他必需营养素，相对量较小。本文旨在了解施肥对可可植株生长的重要性。通过对部分文献研究的描述，可以得出结论:无机肥料和有机肥料在养分含量、持续养分有效性和成本等几个参数上各有优缺点。施用无机肥对可可生产植株的提升作用更快、更高，但不可持续，施用有机肥对可可生产植株的提升作用不可持续。其次，可可植株的施肥必须在组成确定的情况下，无机肥与有机肥相结合。施用无机肥料和有机肥料的单位树可可需要评价多继续进行，研究多根据树龄、生理、土壤类型和方法施用。这符合印尼的地理条件，因为印尼是一个群岛国家，所以每个地区都有不同的特点。

Potato virus S (PVS) is one of the common viruses worldwide and usually produces moderate symptoms in potato plants. The interactions of viral proteins with their hosts are very important in establishing a successful infection and ensuring systemic spread. In this study, the interaction between the PVS coat protein (CP) and the PSH-RGH6 protein in the defense system encoded by the potato plant was investigated using homology modeling and protein-protein docking approach. The CP gene of the PVS-Bitlis isolate was amplified by RT-PCR using gene-specific primers. The gene of interest was cloned into the pGEM-T Easy vector and the plasmid carrying the PVS-Bitlis CP gene was sequenced. By using the amino subsequence of the obtained sequence, I-TASSER program created a protein model based on homology. For the PSH-RGH6 protein, a model of the protein was created using the Swiss-model program. The interaction among both proteins was investigated with the AutoDock approach in Chimera 1.15 program. According to the docking results, the existence of interaction between PVS-Bitlis CP and PSH-RGH6 proteins has been determined and this interaction needs to be confirmed with further analysis.

Cocoa fruit borer attacks all stages of fruit, namely young fruit, mature fruit and ripe fruit. Symptoms of attack on young fruit are indicated by the appearance of large yellow spots on the skin of the affected fruit. His attacks cause an average production drop of 50% with a range of 10% to 90%. The basic method in this writing is descriptive. The data used are the results of previous studies relating to the attack of CPB pests on the decline in cocoa fruit production. The results of the discussion, it can be concluded that the attack of the cocoa pod borer (PBK) is very influential on annual cocoa production. Yield losses due to CPB attacks ranged from 18.25% to 73.04%. However, CPB pests can be controlled through good technical culture measures during cocoa plantation management.

Soil is a natural medium that is one aspect of supporting the life of all living things, including plants. Soil chemical properties greatly affect the growth process of oil palm plants, especially in the production process of oil palm fruit bunches. The purpose of this study was to determine the soil's chemical properties in oil palm plantations. The method used in this study is a descriptive method by conducting surveys and laboratory analysis. Soil samples were taken randomly at a depth of 0-20cm at four points of plantation land. Several parameters have been analyzed, such as pH, total N, CEC and exchangeable Al (Al-dd). Soil samples were analyzed at the Laboratory of Soil Research Indonesian Oil Palm Research Institute (PPKS) Medan. Determination of the criteria for assessing soil chemical properties based on the soil fertility standards issued by the Soil Research Center (BPT) Bogor (2009). The results of the analysis showed that the soil pH was slightly acidic, total N was low, CEC was low and Al-dd was very low.
