Abstract

A water drilling machine is a tool that makes it easier for humans to make dug wells, in the manufacturing process it requires a tool to lift and lower pipes which are relatively large and heavy, so a tool is needed, namely a pulley. Which is following its use to ease in pulling and lowering the machine and the drill pipe. How to analyze the pulley-to-lift ratio of an underground water drilling machine. In drilling a water well with a lift pulley ratio of 1: 4.8 capable of lifting a load of 85 kg with a force of 0.728 kg.

Abstract

Kota besar denga pemukiman yang padat membuat banyak genangan air yang tinggi hal ini disebabkan karena curah hujan yang tinggi serta resapan air tanah yang kurang dan banyaknya sampah yang menyumbat saluran air, untuk menanggulangi banjir dengan cepat salah satunya dengan cara memompa air agar cepat surut, tentunya dengan pompa air debit besar, untuk mendapatkan pompa air yang debitnya besar perlu dilakukannya pengujian debit pompa air dengan cara menganalisis pompa air menggunakan alat skat ukur segi empat, dengan metode ini nilai debit air yang dihasilkan oleh pompa air dapat diketahui. hasil perhitungan ketinggian air menggunakan skat ukur berbentuk segiempat pada ketinggian 9,5 cm didapatkan debit air sebesar 15.175,06 liter/menit.

Abstract

ABSTRACTBackground: Stunting among toddlers is a significant public health issue in Indonesia, with a high prevalence in various regions, including Tegal City. One of the efforts to reduce stunting is through nutritional interventions based on animal protein that is easily available and has high nutritional value.Objective: This study aimed to develop catfish sausage fortified with duck eggs as a local nutrition intervention to improve children's nutritional status.Materials and Methods: The research was an experimental study using a completely randomized design with three formulations (S1 had 1 egg, S2 had 3 eggs, and S3 had 5 eggs), each repeated three times. The formulations adhered to SNI 3820:2024 standard requiring minimum 75% meat content. Parameters analyzed included protein, fat, moisture content, pH, texture, and amino acid profile. Statistical analysis using one-way ANOVA was applied at 5% significance level.Results: Sausages with duck egg fortification had protein content of 14.55-15.62% and fat content of 5.27-9.08%. Sample S2 showed the highest protein (15.62%), optimal texture (hardness 8N, chewiness 4N), and stable pH (6.2) meeting SNI standards. Amino acid analysis revealed significant levels of lysine (1.85%), histidine (1.24%), and leucine (2.95%).Discussion: Duck egg fortification significantly improved nutritional quality. A 50g serving provides 60-70% of daily protein needs for children aged 1-3 years. Essential amino acids play crucial roles: lysine supports bone growth and calcium absorption, histidine aids tissue repair and immune function, while leucine activates mTOR pathway for muscle protein synthesis. Sample S2 demonstrated the most balanced formulation with optimal protein enrichment while maintaining desirable texture and microbiological stability during cold storage.Conclusion: Catfish sausage fortified with duck eggs has potential as an effective local wisdom-based nutritional intervention for stunting reduction in Indonesia.Keywords: Sausage; catfish; duck egg; protein; stunting

Abstract

ABSTRAK Berkurangnya produksi energi fosil terutama minyak bumi serta komitmen global dalam pengurangan emisi gas rumah kaca, mendorong Pemerintah untuk meningkatkan peran energi baru dan terbarukan secara terus menerus sebagai bagian dalam menjaga ketahanan dan kemandirian energi. Sesuai PP No. 79 Tahun 2014 tentang Kebijakan Energi Nasional, target bauran energi baru dan terbarukan pada tahun 2025 paling sedikit 23% dan 31% pada tahun 2050. Daerah kota tegal memiliki garis pantai sekitar 10,2 Km yang belum dimanfaatkan untuk energi listrik, tujuan dari sosialisai ini adalah agar siswa mengenal potensi yang ada disekitar untuk bisa dijadikan energi listrik yang ramah lingkungan. Tujuan untuk memberikan pengetahuan akan energi terbarukan salah satunya pemanfaatan energi matahari, Hasil pengabdian pada masyarakat dalam bentuk Iptek bagi Masyarakat (IbM) yang telah dilaksanakan terdapat peningkatan pengetahuan siswa SMK tentang konversi energi terbarukan dan siswa mampu mempraktikkan instalasi panel surya serta mampu mempraktikkan penggunaan alat ukur arus dan tegangan yang keluar dari panel surya sehingga bisa membuat instalasi panel surya sesuai dengan kebutuhan. Kata Kunci : Energi Listrik, Energi Matahari, Panel Surya

Abstract

This study discusses the effect of feed rate and machine rotation speed on the surface roughness of ST 41 steel in the flat turning process. The aim is to determine the relationship between variations in rotation speed (100 rpm, 300 rpm, and 500 rpm) and feed rate on the final surface results of the workpiece. The method involves cutting tests on ST 41 steel specimens with a diameter of 25 mm and a length of 400 mm with various rotation speed variations. The results show that at low rotation speed (100 rpm), the surface of the workpiece tends to be rough. The surface becomes better at medium speed (300 rpm), while at high speed (500 rpm), the surface results are smoother. These findings indicate that increasing rotation speed contributes to a decrease in surface roughness. Thus, higher rotation speeds can improve the quality of turning results.

Abstract

A fuel is a compound that contains hydrocarbon elements. Pertalite is a fuel quality that has an Octane Research Number 90. LPG is made from petroleum gas material formed from Propane and Butane. The water pump drive engine is a pertalite-fueled internal combustion motor but may replace with LPG. The main reason is the cheap purchase price. Using LPG gas as a substitute for pertalite fuel is interesting research that will be conducted to conduct experiments testing pertalite fuel consumption with LPG gas. The results obtained in this study, namely using rice field water pumps with LPG gas fuel, resulted in lower consumption than pertalite fuel by 32% when without load and 28% when with the load.
