: Sugar palm (Arenga pinnata) is one of non-timber forest product that has long been known as a plant that has many benefits. Almost all physical parts of these plants can be utilized and have economic value, such as juice sap, palm fruit, leaves, palm fiber, and stems. Palm sugar plants are spread in almost regions in Indonesia, especially in humid areas both grow individually or in groups. This study aims to identify the potential of palm trees (Arenga pinnata) in Pastap Julu village around Batang Gadis National Park area. The method used in this research is the census method. This method was done by recording the entire of sugar palm in the research area with an area of 60 hectares. The result of this study indicates that the potency of sugar palm (Arenga pinnata) plants in the region is amount to 256 sugar palms with a density of 4.267 individuals /hectare, and the average height of 12 meters and average diameter of 53.08 cm.

: Upland rice yield is highly dependent on nutrients and water availability, temporal and spatial conditions of the climate and the length of planting time period. The effect of planting time and biochar application on upland rice yields varieties were investigated at Zone D Oldeman Agroclimate in North Sumatera. Five upland rice varieties (Batutegi, Inpago 4, Limboto, Situpatenggang, Situbagendit) were evaluated under four planting times and four biochar applications (no rice husk biochar, rice husk biochar, rice husk biochar +chicken manure, rice husk biochar+ EM 4 ). Results showed that biochar application increased plant growth and yield significantly. Application of rice husk biochar + chicken manure produced the highest mean of plant height, leaf chloropyll content, total leaf area, yield per plot and harvest index, while ricehusk biochar + EM4 produced the highest mean number of productive tiller per hill. The Planting time (15 th Sept ) period IV recorded the highest mean of all parameter excluding harvest index which the highest value were at period II. And Inpago 4, Limboto, Batutegi varieties showed the higher growth and yield performances among the four different planting times at zone D Oldeman Agroclimate.

: Every year we import wheat flour from other countries to supply domestic needs in making noodles. There were many plants from local resources that can be used as flour to substitute wheat flour, like pumpkin. This research deal about making flour from pumpkin fruit, effect of composite flour (wheat and pumpkin flour) and the type of stabilizers on the quality of dry noodles. The pumpkin flour can subtitute wheat flour about 20% to make dry noodles.

Sustainable supply chain management (SSCM) is management that integrates economic and non-economic problems in the supply chain. They found it difficult to adopt high influence in other practices to adopt SSCM. These practices are effectively identified and applied, enabling many other practices; the company can then follow all required SSCM practices.

Kandelia, a genus belonging to Rhizophoraceae has been reported to have two distinct species: K. candel and K. obovata. Mangrove plants are known to produce secondary metabolite mostly derived from isoprenoid (triterpenoid and phytosterol). Isoprenoid composition of leaves and roots of K. candel (L.) Druce and K. obovata Sheue, Liu & Yong were investigated and compared. Triterpenoid and phytosterol profile of both species was analyzed using Gas Chromatography with Flame Ionization Detector (GC-FID). Both species displayed difference composition either in the leaves or roots. In the leaves of K. candel, eight isoprenoids detected, with dominating of -amyrin, a member of triterpenoid. The ratio between triterpenoid and phytosterol was 73.2%:26.8%. By contrast, phytosterol dominated the isoprenoid proportional in the roots of K. candel (91.7%). Similar results were found in the K. obovata leaves and roots, a predominated phytosterol over triterpenoid, 59.6%, and 97.9%, respectively. The present work suggested diversity composition of isoprenoid in both Kandelia.
据报道，坎德尔属属于根参科，有两个不同的种:坎德尔和obovata。红树林植物已知产生次生代谢物，主要来源于类异戊二烯(三萜和植物固醇)。香椿叶和根的类异戊二烯成分Druce和K. obovata Sheue, Liu & Yong进行了调查和比较。用气相色谱-火焰离子化检测器(GC-FID)分析了两种植物的三萜和甾醇谱。两种植物在叶和根的组成上都存在差异。在山楂叶中检测到8种类异戊二烯，以三萜中的-amyrin为主。三萜与植物甾醇的比值为73.2%:26.8%。相比之下，植物甾醇在蜡烛根的类异戊二烯比例中占主导地位(91.7%)。结果表明，黄叶莲叶片和根中植物甾醇含量高于三萜，分别为59.6%和97.9%。本研究表明，两种植物中类异戊二烯的组成存在差异。

Taxus sumatrana is an important medicinal plant as a source of cancer drugs and indicated to cure various cancer. However, information about habitat and population especially in Northern Sumatra is very limited. This research aimed to observe the population and habitat of Taxus sumatrana in three locations (Gunung Tujuh, Gunung Kerinci and, Sibuaton) and implication in conserving this species. Data was collected by creating a plot analysis with strip transect method and data were analyzed by analysis of Important Vegetation Index, species diversity index, community similarity index and abundant index. The result showed that taxus population in all location was not in normal distribution which was lacking seedling, sapling, and poles level of stands. The overall diversity of the three study sites was still high enough so that the condition remains relatively stable. All the study sites have a low similarity value so it can be used as a location for genetic protection of plant distribution. As an implication, taxus habitat should be highly protected by a special rule to protect its existence as well as species enrichment to reduce growth level of this species.
