Abstract

Terjadinya masalah engine black smoke pada engine C6.4 Caterpillar, ditandai dengan keluarnya asap keabu-abuan cenderung kehitaman, dan ketika diberi tenaga maksimal engine seakan-akan cenderung mati (low power). Untuk mengetahui penyebab kerusakan dan menentukan upaya pencegahan agar kerusakan tidak terulang kembali, telah dilakukan troubleshooting terhadap masalah yang terjadi. Troubleshooting dilakukan dengan 4 tahap yaitu tahap pendefinisian masalah, tahap evaluasi masalah, tahap perbaikan, dan tahap analisa. Dari hasil troubleshooting yang telah dilakukan, ditemukanlah akar masalah penyebab engine black smoke dari engine C6.4 Caterpillar yaitu rusaknya aftercooler yang mengalami kebocoran yang mengakibatkan udara panas dari turbocharger tidak bisa didinginkan dan udara tidak menjadi padat, sehingga udara yang masuk ke ruang bakar tidak mencukupi sesuai kebutuhan engine. Adapun penyebab terjadinya kerusakan pada aftercooler karena, adanya tekanan dari sebuah benda seperti kayu atau lain sebagainya, yang mengakibatkan sirip-sirip pada aftercooler bengkok dan bocor. Mengenai masalah ini, upaya penanggulangan yang dilakukan adalah penggantian pada aftercooler. Setelah penggantian, dilakukan pengetesan dan engine beroperasi dengan normal.

Abstract

Beberapa masalah dalam bidang pertanian di Indonesia berdampak negatif terhadap indeks ketahanan pangan. Sistem akuaponik dapat mengatasi hal tersebut karena sistem ini menghasilkan ikan dan tanaman dengan ramah lingkungan sehingga memungkinkan proses instalasi yang mudah. Desa Grenden yang terletak di Kecamatan Puger, Kabupaten Jember, sebagian wilayahnya masih tergolong lahan sawah produktif namun minat pemuda bekerja di bidang pertanian kurang. Permasalahan lain yaitu pabrik sedang melakukan pengurangan tenaga kerja secara besar-besaran yang menyebabkan banyaknya pemuda yang awalnya sebagai buruh kasar di pabrik menjadi pengangguran. Hal ini yang mendasari tim pengabdian dari Program Studi Teknik Kimia Universitas Jember untuk melakukan sosialisasi mengenai penerapan sistem akuaponik. Berdasarkan hasil diskusi dengan mitra terkait permasalahan yang dihadapi, kegiatan ini menggunakan metode sosialisasi dan pendampingan dalam menerapkan integrated farming berbasis zero waste yaitu dengan konsep pertanian akuaponik. Metode kegiatan yang dilakukan, yaitu memberikan sosialisai mengenai penerapan pertanian terpadu dengan sistem akuaponik. Sosialisasi dilakukan agar karang taruna Desa Grenden mampu menciptakan peluang usaha yang dapat diterapkan. Hasil sosialisasi menunjukkan bahwa masyarakat Desa Grenden memahami konsep mampu menerapkan sistem akuaponik.

Abstract

Perkembangan perumahan akhir ini sangat pesat, sehingga konsumen seringkali ragu ketika harus langsung memutuskan rumah mana yang dibeli. Konsumen harus lebih berhati-hati saat memilih perumahan. Memilih tempat tinggal dapat didasarkan pada beberapa kriteria, di antaranya rumah harus sehat, nyaman, dan aman. Dalam penelitian ini, penulis mengambil sampel perumahan dari lima rumah di Kabupaten Langkat Sumatera Utara. Tujuan dari penelitian ini adalah untuk menganalisis kriteria apa saja yang dibutuhkan saat memilih perumahan, kami juga mencari alternatif akomodasi yang memenuhi kriteria yang diinginkan. Kriteria pemilihan perumahan adalah Lokasi (C1), Kamar Tidur (C2), Ruang tamu (C3), Dapur (C4) , Kamar Mandi (C5), Laundry Room (C6), Luas Bangunan (C7), Air (C8), Harga (C9), Jenis bangunan (C10). Dalam penelitian ini, penulis menggunakan metode TOPSIS (Technique for Order Preference by Similarity to Ideal Solution), yaitu metode yang konsepnya didasarkan pada kedekatan suatu alternatif terhadap solusi ideal, disebut juga dengan nilai preferensi. Setelah dilakukan uji TOPSIS, diketahui bahwa dari 5 sampel perumahan memberikan nilai preferensi yang lebih tinggi yaitu 0,767 , sehingga keputusan pemilihan perumahan terbaik adalah Perumahan yang ke 2. Metode TOPSIS mampu membuat rekomendasi pemilihan perumahan terbaik dengan hasil perhitungan lebih cepat dan akurat, sehingga informasi yang diperoleh dapat digunakan untuk pendukung keputusan.

Abstract

Fermentation is a food processing technique that utilizes microorganisms to extend shelf life, enhance nutritional value, and produce safer products with unique flavor characteristics. The fermentation process can occur naturally or with the addition of a starter, depending on the type of product being produced. This technique has been widely applied in traditional food processing across various regions, using raw materials such as soybeans, vegetables, tubers, milk, and meat. Fermented products serve not only as food sources but also as functional foods that benefit health, including as sources of antioxidants and probiotics. This study examines the advantages of fermentation as a preservation method and explains the biochemical processes that occur during fermentation, including the role of lactic acid bacteria (LAB) in improving the quality of the final product.

Abstract

This research endeavors to employ sales forecasting techniques on historical sales data for the purpose of determining the sales budget. The application of forecasting is based on sales data from the preceding period, utilizing a descriptive qualitative method. The analysis employs the half-average trend method, generating an estimated sales figure for the upcoming period. This estimate serves as a reference for both inventory planning and the formulation of the sales budget. Within this research, the half-average trend method involves the selection of two X parameter values, namely 0.5 and 0. To determine the superior value, a calculation of SKF (Standard Error of Forecasting) is executed. The analysis results reveal that utilizing the value 0 yields an SKF value of 4,166.6, while the value 0.5 produces a lower SKF value of 3,941.6. This implies that the estimated sales number with the X value of 0.5 is smaller than that with the X value of 0. Conclusively, the application of the half-average trend method in this research provides sales estimates for the next three months, contributing valuable insights for effective planning and budgeting processes.
