Abstract

Sentool Plantation is a plantation area, agro-industrial and agro-tourism are located in Suci Village, Panti District, Jember Regency. This area is at the foot of Mount Argopuro with abundant water sources. In this area there is a river flow that can be utilized as a micro-hydro power plant (PLTMH). PLTMH is a relatively easy power plant to make and apply in rural areas or villages. PLTMH was chosen as an alternative energy source with the principle of developing renewable energy Therefore, in this community service activity want to effort to analyze potency of electric power generation and optimization of the MHP System at the Sentool Plantation which is useful as a consideration PLTMH development to meet the electricity needs of the local community and electricity needs for the development of agro-tourism. Power potential analysis process and optimization of the PLTMH system is carried out with two stages of data analysis, namely the calculation of the potential power theoretical and simulation using HOMER Energy software. HOMER Energy is used for profit simulation. The greatest potency generated power is 53.12 kWh with a discharge of 0.398 m3/s and the smallest is 18.05 kWh with a discharge of 0.135 m3/s. Simulations using HOMER Energy software produce system configurations PLTMH with an estimated capital cost of IDR 48,600,000, operational costs and maintenance 42,900,000 per year, NPC of IDR -2,557,215,000, LCoE of IDR-573.63. PLTMH has a capacity of 37.1 kW with annual production of 290,573 kW, get a profit of IDR 212,747,987.50 from the sale of energy. The results of the calculation of the water discharge, the height of the water fall and the generated power are quite high, the water flow in the Sentool Plantation is technically feasible to build a micro-hydro power plant (PLTMH).

Abstract

Furniture (chairs, beds, sideboards and so on) are items needed by every household that potential to be cultivated as a livelihood. Some of the basic materials for making furniture products are available locally (village) and some come from the city. Techniques for making furniture products such as how to make wooden frames, cut furniture cloth or leather, sew furniture fabrics, and the process of assembling and combining them into a furniture product must be owned by furniture workers, in order to open a furniture business. In addition to the technical skills that must be possessed, the required equipment such as tools, sewing machines and so on must also be owned for this furniture business to be successful. Some of the difficulties of Jelbuk furniture entrepreneurs are that they do not have enough skills to sew and do not have a sewing machine. If there is sewing work, it is always given to another party whose existence is 20 km from Jelbuk. This is what makes Jelbuk entrepreneurs less economically empowered. Therefore, the purpose of carrying out this activity is to provide guidance on sewing techniques and procurement of sewing machines as an alternative solution for these furniture entrepreneurs. This activity was carried out in several stages, namely 1) procuring sewing machines that were tailored to the needs of making a furniture product, 2) providing guidance on sewing techniques, and 3) training on techniques for making fashion furniture products according to consumer tastes. Guidance on sewing techniques is given starting from getting to know the sewing machine and its characteristics as well as sewing guidance to make a simple product to the details. The results of the community service activities are enough to help improve the ability of sewing techniques so that all pron products can be done at their own place without having to be given to other parties, so that the completion is faster and more cost efficient. The guidance process is still given for 3 months until it is completely independent. The ability of furniture entrepreneurs increases, the settlement process is faster, the number of consumers increases and will ultimately increase the income of furniture entrepreneurs in Suger Kidul Village, Kec. Jelbuk, Kab. Jember.
