Penerapan Kemasan Aktif dan Sekunder pada Keripik Buah di UMKM Darsa Lampung Timur
No full textMSMEs Darsa is a firm that takes advantage of East Lampung's bountiful fruit. Vacuum fraying is used by these MSMEs to make fruit chips. However, in order to achieve a lengthy shelf life, these MSMEs face challenges in the packaging process. Fruit chips can sometimes suffer from quality deterioration, such as becoming less crispy after being stored. Therefore, the solution proposed is to transfer and apply packaging technology, namely silica gel as moisture absorbance. Furthermore, supplementary packaging was used to increase sales. This program begins with discussions with partners to the implementation of premium full printing and stand up zipper lock windows as primary packaging. Goodie bag was chosen as the secondary packaging and silica gel as the active packaging. The results include publications in the mass media; the absence of damaged products; increased shelf life; partners understand the application of active packaging; poster; and videos of activities
ANALISIS RUGI-RUGI DAYA KABEL DC PADA PLTS 1MWP ON-GRID INSTITUT TEKNOLOGI SUMATERA BERDASARKAN DATA FUSION SOLAR
Get PDFPLTS 1 MWp on-grid at the Sumatra Institute of Technology (ITERA) campus comprises solar modules, inverters, DC cables, and protection equipments assembled in a compact system. Each of these components has a role in transmitting the electrical energy generated by the solar module to the electrical load at ITERA. This paper will discuss the power losses generated by PLTS components, especially the DC distribution cables used. The simulation of PVSystV6.81 obtained 1.98% of the losses resulting from the distribution process on the DC cable. The simulation results were compared with the measurement results from the solar fusion software, which records the power components generated by PLTS ITERA such as voltage, current, power, etc. for each string connected to the inverter with a data collection duration of 5 minutes (12 hours per day 06.00 – 18.00). Based on data obtained from fusion solar in August and formula calculation, the lowest average percentage loss of energy from DC cables is 0.6542% on inverter 6, and the highest is 0.6718% on inverter 1. The difference losses of each inverter are caused by disturbances in the DC cable distribution line from the module to each inverter, such as short circuit current to ground
