Application of Min-Max Stock Method in the optimization of auxiliary raw material inventory in the biodiesel industry
No full textInventory is an aspect of manufacturing operations to ensure the availability of raw materials while minimizing costs. PT. Permata Hijau Palm Oleo Belawan, a biodiesel company, faces challenges in balancing the inventory levels of key auxiliary raw materials such as Methanol, Catalyst, NaOH, Inventory is an aspect of manufacturing operations to ensure the availability of raw materials while minimizing costs. PT. Permata Hijau Palm Oleo Belawan, a biodiesel company, faces challenges in balancing the inventory levels of key auxiliary raw materials such as Methanol, Catalyst, NaOH, and HCl. Excessive inventory results in high storage costs, while inventory shortages can disrupt production continuity. This study aims to evaluate the effectiveness of the Min-Max Stock method in optimizing auxiliary raw material inventory at PT. Permata Hijau Palm Oleo Belawan, addressing its practical impacts on cost reduction and efficiency improvement in the palm oil-based biofuel industry. This study uses a quantitative approach, utilizing historical data on the purchase and usage of raw materials during the 2019-2020 period. The Min-Max Stock method is applied to determine the optimal inventory level, comparing the actual inventory level with the calculated minimum and maximum thresholds. The implementation of the Min-Max Stock method can save storage costs of around IDR 35 billion. The implementation of the Min-Max Stock method offers a solution that increases efficiency, reduces costs, and prevents production disruptionsand HCl.

Pertumbuhan dan Produksi Jagung Manis (Zea Mays L. Saccharata) dengan Aplikasi Pupuk Organik Cair Bonggol Pisang dan Pupuk Kandang Sapi
No full textLiquid organic fertilizer has many advantages. This research aims to determine whether giving banana weevil POC and giving cow manure can increase the growth and production of sweet corn (Zea mays L. sacharata) and their interactions.This research used a Randomized Block Factorial Design with 2 factors studied and 3 replications where the first factor was the administration of banana weevil POC (P) which consisted of 3 levels, namely P1 = 100 ml liters of water-1 plot-1, P1 = 200 ml liters of water -1 plot-1, P2 = 300 ml liter of air-1 plot-1. The second factor of giving cow manure (S) consists of 4 levels, namely S0 = no treatment (control), S1 = 2 kg plot-1, S2 = 4 kg plot-1, and S3 = 6 kg plot-1. The parameters observed were plant height (cm), weight of husked cobs per sample (g), and husked cob weight per plot (g).The research results showed that giving POC banana weevils had no significant effect on the parameters of plant height, weight of husked cobs per sample, and husked cob weight per plot. The application of cow manure had a very significant effect on the parameters of plant height, weight of husked cobs per sample and husked cob weight per plot. The interaction of the two fertilizer treatments had no significant effect on all observed parameters

Because the majority of Indonesians like fried food, cooking oil is still needed for household needs. Used cooking oil, oil produced from frying, is often used to save money, but its carcinogenic properties can cause cancer in the future. The purpose of this activity is to change the paradigm and change the paradigm of PTPN III Sei Mangke mothers. The results of this activity were 25 people, namely the age range of 28-37 years with a percentage of 36%, and the highest education level was high school with a percentage of 48% and there was a paradigm shift where previously they did not know until they understood based on the results of the questionnaire survey of the activit
The Effect of fuel mixture composition on gasoline engine emissions in urban conditions
No full textThe increasing number of motorized vehicles in urban areas significantly impacts air quality and public health. Gasoline engine emissions, including CO, HC, and NOx, contribute to pollution issues such as volatile organic compounds (VOCs) and secondary organic aerosols (SOAs). Understanding these factors is crucial for developing effective emission control strategies. This study investigates the effect of ethanol-blended gasoline on vehicular emissions, focusing on CO, HC, and NOx. The research aims to optimize fuel mixtures to reduce harmful emissions while considering environmental and health impacts. The study uses a quantitative experimental design, combining laboratory tests with field trials on 10 vehicles under controlled conditions. Results show that ethanol-blended fuels significantly reduced CO emissions, from 2.4 g/km (E0) to 1.5 g/km (E30). A moderate reduction was observed in HC emissions, from 0.55 g/km (E0) to 0.40 g/km (E30). A slight decrease in NOx emissions was noted. Ethanol's oxygen content improves combustion efficiency, reducing CO and HC emissions, but may slightly increase NOx due to combustion temperature changes. This study highlights the potential of ethanol as an environmentally friendly fuel alternative, with further research needed to address NOx-related challenge

Pelatihan dan implementasi perencanaan pencahayaan dan sirkulasi udara untuk lingkungan sehat dan nyaman pada Proyek Pembangunan Gedung UMKM-USU
No full textKualitas udara dalam ruangan yang buruk di gedung perkantoran dapat menurunkan produktivitas dan kesehatan pekerja. Penelitian ini bertujuan mengevaluasi efektivitas pelatihan dalam meningkatkan pemahaman dan penerapan sistem ventilasi yang baik di gedung Usaha Mikro, Kecil, dan Menengah (UMKM)-USU. Metode penelitian yang digunakan adalah kombinasi antara kualitatif (Focus Group Discussion) dan kuantitatif (survei). Hasil penelitian menunjukkan peningkatan signifikan dalam pemahaman peserta pelatihan mengenai pentingnya kualitas udara. Namun, implementasi sistem ventilasi yang efektif masih terkendala oleh beberapa faktor, seperti keterbatasan anggaran dan kurangnya kesadaran manajemen. Penelitian ini menyimpulkan bahwa pelatihan merupakan langkah awal yang baik, namun perlu didukung oleh kebijakan yang lebih komprehensif dan keterlibatan berbagai pihak untuk mencapai kualitas udara dalam ruangan yang optimal di gedung UMKM. Keterbaruan penelitian ini terletak pada fokusnya pada UMKM di Indonesia dan identifikasi kendala spesifik yang dihadapi dalam konteks loka
