Andaliman has the Latin name Zanthoxylum acanthopodium and is a family of Rutaceae. Andaliman is anative spice from North Sumatra called the golden spicy from North Sumatra. Andaliman farmers inParsoburan Village, Toba Samosir said that one of the problems in andaliman production is the number ofAndaliman fruits that are still not effective, even most of the Andaliman fruit becomes rotten. The design ofAndaliman perfume machine has been carried out which aims to increase the usefulness of Andalimanthrough the manufacture of andaliman perfume as well as to increase the economic value of Andaliman. Themethod used is by designing a perfume machine and making an official perfume machine, testing the machineand using a perfume machine. Making perfume machines and testing perfume machines was carried out atthe UNIMED Mechanical Engineering Workshop and the implementation of machine use activities wascarried out in Parsoburan, Toba Samosir Regency. The results obtained from the andaliman smoothingmachine were processed as 2 kg of perfume in a single smoothing process, for the heating stage mixed with300 mL ethanol and the results of the perfume ± 20 mL which will be mixed with alcohol according to thestrong aroma made.

Abstract Sumatra has extensive forests, rich in tree species, especially the Dipterocarpaceae species, which have high economic and ecological value in the development sector. The enormous number of Dipterocarpaceae species and the paucity of herbarium collections make identifying species quite easy. The study’s goal was to learn more about the Dipterocarpaceae family tree’s species, diameter, and height in the Mandailing Natal Forest Production Management Unit (KPHP ) in North Sumatra. Diameter and height data of Shorea sp was based on secondary data processing. The inventory revealed that the Dipterocarpaceae family has 12 different species. Trees in the Dipterocarpaceae family have an average diameter of 44.5 cm and a height of 20 cm. This inventory is expected to offer information on the several Dipterocarpacea families that can be found in this area, particularly those with high economic value and those that are protected.

Abstract Pasak bumi (Eurycoma longifolia) is a medicinal plant with various benefits and has long been used to cure various diseases such as cancer, gingivitis, intestinal worms, and anti-inflammatory anti-malarial, and tonic after childbirth. The root has high economic value leading to unsustainable harvest and drastic population decline. As initial data in conservation activities, information regarding the association of pasak bumi in Batang Lubu Sutam natural forest has not been obtained. Therefore, this research was conducted to determine the pasak bumi distribution and its association within their natural habitat in Batang Lubu Sutam forest. The study was conducted by using the vegetation analysis method using a plotted path determined by purposive sampling. Data analysis was performed by calculating association indices, including the Ochiai index (Oi), Dice index (Di), and Jackard index (Ji). The results showed that pasak bumi were found in the seedling and sapling stage in the research location and form a degree of association with several plants. The species that formed the highest degree of association with the pasak bumi at both levels of regeneration was Shorea leprosula with an Ochiai index value of 0.85 at the seedling level and 0.94 at the sapling level.

Oshibana is known as a flower processing technique so that it can produce crafts with a drying method without changing the original color of the flowers. Oshibana technique aims to produce handmade products with raw materials that come from nature, are environmentally friendly and have high selling value. Partners in this community service activity are the youth of Padepokan Igra, Kolam Village, Percut Sei Tuan District, North Sumatra. This activity aims to provide information to partners about the potential of home garden plants to be used as creative products with artistic and economic value and to introduce oshibana techniques. The implementation of the activity is carried out using 2 methods, namely the presentation of material and the delivery of information related to the potential of homegarden plants as raw material for industrial products and the direct practice of making oshibana. Through this community service activity, it is hoped that the youth at the Iqra hermitage can increase their insight and knowledge about the use of waste yard plants as raw material for creative artistic and economic products and can create jobs while supporting eco-green programs and save our earth.

Abstract Eurycoma longifolia is one of the potential medicinal plants and has a high economic value if developed. The bioactive compound produced by E. longifolia has potential as medicine, thus causing increased exploitation of their habitat. This condition resulted in the decreasing population of E .longifolia in nature. The distribution of E. longifolia is influenced by soil fertility conditions. The presence of phosphate solubilizing fungi and cellulolytic fungi in the soil can support the growth of E. longifolia in nature. The purpose of this study was to calculate the population of phosphate solubilizing and cellulolytic fungi and to identify the types of phosphate solubilizing and cellulolytic fungi found in the soil under E. longifolia stands. Soil samples were taken randomly at a depth of 0–20 cm in a natural forest of Papaso Village, Lubu Sutam District, Padang Lawas Regency, North Sumatra. Population and isolation of phosphate solubilizing and cellulolytic fungi were obtained by dilution methods. The isolates obtained were identified morphologically to the genus level by macroscopic and microscopic observation of colonies. The results showed that the population of phosphate solubilizing and cellulolytic fungi were 6.64 × 104 CFU/mL and 9.31 × 103 CFU/mL, respectively. The isolation results in 11 isolates of phosphate solubilizing and 10 isolates of cellulolytic fungi. Based on the morphological identification of phosphate solubilizing fungi isolates consisted of 5 genera, namely Aspergillus, Penicillium, Rhizopus, Fusarium, and Mucor, while isolates of cellulolytic fungi also included 5 genera, namely Aspergillus, Cladosporium, Penicillium, Rhizopus, and Mucor.

Amarilis is one of the flower of the park that is attractive and has high economic value. This study aims to determine the effect of vernalization on the appearance of local amaryllis plants in Tanah Karo and West Sumatra. This research was conducted at the Plant Breeding Basic Laboratory of the Faculty of Agriculture, University of North Sumatra, Medan, from February 2018 to July 2018. This research was carried out by storing tubers at room temperature (control) and storage of tubers at low temperatures (vernalization) at 10 oC for 6 weeks, and with differences in accession of plants namely G1 (Accession of West Sumatra Payakumbuh), G2 (Bukit Tinggi West Sumatra Accession), G3 (Padang Panjang West Sumatra Accession), G4 (Local Kabanjahe Accession Tanah Karo), G5 (Berastagi Local Accession Tanah Karo ), G6 (Tanah Karo Local Accession Accession). The results showed that vernalization gave a different appearance compared to the control treatment.

The livestock business is a business consisting of fattening and breeding. Cows are one of the food producers that have a lot of value and nutrition. The high economic value is in line with the increase in population, and the need for food consumption in Indonesia continues to increase every year. Therefore, we must be able to cope with the increasing demand for meat. One of these needs is raising cattle or animal feed and understanding the livestock supply chain as seen from the decline in livestock and feed prices in the market. Knowledge of supply chain flow and beef cattle marketing efficiency is an alternative solution to ongoing problems. The research location is in Percut Sei Tuan District, Deli Serdang Regency, North Sumatra, considering that Percut Sei Tuan District is one of the sub-districts that runs a beef cattle business. This study aims to see how the efficiency of beef cattle marketing. The method used is measuring marketing efficiency and looking at the farmer's share in the beef cattle supply chain. From the study results, it was found that the marketing efficiency analysis of each of the beef cattle supply chain actors in this study has reached a high level of efficiency starting from suppliers, farmer groups and retailers.
