Abstract

Palm fronds resulting from the pruning process can be used as organic fertilizer and animal feed.Communities in Bengkalis Regency, especially in Pinggir District, are still constrained in the processing of palmmidrib to be used as animal feed, especially in the process of mixing or stirring. The purpose of this research is todesign and manufacture a horizontal type animal feed mixer machine and to test the performance of the machine.This research activity will later conduct machine performance trials at research partners and conduct training onthe use of machines and hand over machines to research partners to be utilized or used in the process of mixinganimal feed.

Abstract

Potensi perikanan Republik Indonesia memenangkan pasar MEA (Masyarakat EkonomiASEAN) dan produk makanan olahan hasil laut telah meraih green ticket yang dikeluarkan oleh USAFDA sehingga beberapa industri pengolahan hasil laut menembus pasar AS dan Eropa. Desa PanipahanKecamatan Pasir Limau Kapas sebagai besar bermata pencaharian sebagai nelayan. Merekamemanfaatkan hasil tangkapan berupa udang rebon untuk diolah menjadi terasi, untuk mengetahuiperbandingan kapasitas hasil gilingan dengan variasi diameter lubang pengeluaran alat penggiling terasidan untuk mengetahui rendemen dengan variasi diameter lubang pengeluaran..Upaya untuk pembuatanalat ini menggunakan extruder yang berfungsi untuk menggiling udang rebon kebagian die.Hasildesakan udang rebon tersebut kemudian digiling dengan jumblah pisau penggiling 2 mata pisauyangdipasang bertingkat dengan kecepatan 1400 RPM dengan daya 1 Hp. Menggunakan sistempenggiling ini bahan baku dapat tergiling lembut yang kemudian dikeringkan dan dibentuk sesuai dengakebutuhan. Untuk menegetahui bahwa terasi hasil dari alat itu layak untuk dipasarkan ataupundikosumsi maka dilakukan pengujian densitas. Setiap perbedaan lubang keluaran maka berbanding lurusdengan perbedaan hasil berat terasi yang mana diameter lobang keluaran 3 mm menyusut dalam waktu8,49 menit, 8,55menit dan 9,11 menit. Diameter lubang keluaran 4 mm menyusut dalam waktu 6,29menit, 6,40 menit, dan 7,21 menit, dan diameter lubang keluaran 5 mm menyusut dalam waktu 6,9menit, 6,12 menit, dan 7,11 menit. Semakin lamawaktu penjemuran udang rebonsemakin basar pulanilai penyusutan pada berat udang, begitu juga semakin kecil lubang diameter dies akan menghasilkannilai densitas yang tinggi.

Abstract

The making process of Lempuk Durian is almost same  as Dodol’s, the difference is only at the mixing of sticky rice (ketan). Dodol is made with the mixing of sticky rice while Lempuk isn’t. Durian flesh is separated by its contents and then finely ground with a grinding machine. The process of separating the contents and seeds of durian fruit is still using conventional methods, by using a punch-filled basket while being pressed by hand. This way can cause injury to the hand, this way can cause injury to the hand, requires a long time and workers get tired more quickly. The purpose of this research is to make content and durian seed separator machines and conduct performance analysis. This content and durian seed separator machine has a capacity of 20kg / production. After testing and observing the durian seed separator machine, then the performance analysis is carried out to determine the ability of the machine. Machine working capacity (KKM) is obtained at 1 kg / minute with the value of the separation of contents and durian seeds of 87%.

Abstract

A water tube boiler is a critical utility unit in the palm oil processing industry because it supplies steam for power generation and production processes. Component failures in boiler systems may cause production downtime, efficiency losses, and increased maintenance costs. This study aims to analyze the risk level of water tube boiler component failures using the Failure Mode and Effects Analysis method. The research was conducted on two water tube boiler units in a palm oil processing industry using historical maintenance data from January to December 2024. The analysis was performed by identifying failure modes, assigning severity, occurrence, and detection scores, and calculating the Risk Priority Number for each failure mode. The results showed that the highest risk in Boiler 1 was economizer tube leakage with an RPN value of 360. Meanwhile, the highest risk in Boiler 2 was ID Fan ducting failure with an RPN value of 450. The average RPN values for Boiler 1 and Boiler 2 were 233.48 and 242.63, respectively. These findings indicate that maintenance priorities should focus on the economizer, ID Fan, feed water pump, and conveyor system. This study provides a risk-based basis for determining critical components and improving boiler maintenance planning.
