Abstract

Penelitian ini bertujuan untuk mengembangkan sistem alat pengukur sudut kontak yang merupakan salah satu metode penentuan karakteristik permukaan material kayu. Data analisis yang dihasilkan oleh sistem alat yang sudah purwa rupa ini, berupa citra digital berbentuk video lalu dipotong pada kelipatan 10 detik dengan perangkat lunak GOM Player. Sudut kontak dari setiap potongan gambar tersebut kemudian diukur dengan menggunakan aplikasi Image J dan diambil data nilai sudut kontak pada detik ke 100, 200 dan 300 dengan 7 kali ulangan, lalu ditentukan nilai %RSD untuk menentukan tingkat kepresisiannya. Hasil pengolahan data sudut kontak secara statistik menunjukan tingkat presisi yang baik. Hal tersebut dapat dilihat dari hasil pengukuran sudut kontak cairan finishing pada kayu mahoni yaitu  (46,379 ±1,728)O dengan nilai RSD sebesar 3,73%  pada waktu pengambilan gambar 100 detik, ( 45,335±1,930)O dengan nilai RSD sebesar 4,26% pada waktu pengambilan gambar 200 detik dan (44,198±1,170)O dengan nilai RSD sebesar 2,65 % pada waktu pengambilan gambar 300 detik. Pengukuran sudut kontak yang presisi menjadi hal penting untuk akurasi penentuan karakteristik material yaitu tingkat keterbasahan, hidrofobisitas, dan tegangan permukaan serta aplikasinya yang luas di bidang pendidikan, penelitian dan industri.

Abstract

Literature studies on the application of the inclining test, in accordance with BKI (Indonesian Classification Bureau) standards, have been widely applied to large ships. But in practice in the field, large ship media is difficult to obtain. In supporting ship building practicum and ship stability, especially in inclining test practicum, a miniature ship is really needed to help students understand ship building, ship stability, and understand the inclining test procedure which is a benchmark for ship stability. So in this study, focusing on ship design, for fabrication of ship buildings and the addition of lubricating media, as well as calculation tables as a guide in carrying out building practicum and ship stability. In the fabrication of miniatures that have been produced, the stability point values are KG = 3.54 cm, KM = 20.17 cm, KB = 3.41 cm, GM = 16.63 cm, and BM = 16.73 cm where the results are has been obtained in accordance with the theory of stability where the position of each point is in accordance with the top order of K, G. B. and M.

Abstract

Teknologi pengolahan limbah ternak sapi untuk produksi biogas skala rumah tangga. Dalam praktikum pengolahan limbah peternakan dilakukan perlakuan perbandingan kompisisi campuran air dengan limbah kotoran ternak sapi dalam produksi biogas. Digester terbuat dari drum plastik 60 liter kemudian diisi slurry sebanyak 40 liter. Waktu pengamatan dilakukan selama 10 hari. Perbandingan komposisi campuran air : kotoran = 1 : 1 ; 1,5 : 1 ; 2 : 1. Kemudian melakukan pengujian kualitas gas metananya di Balai Penelitian Lingkungan Pertanian Jaken, Pati Jawa Tengah. Dari hasil percobaan, diperoleh kadar gas metana sebesar 228406,38 ppm pada perbandingan air : kotoran ternak = 2 : 1, 195337,56 ppm pada perbandingan air : kotoran ternak = 1 : 1 dan 110969,13 ppm perbandingan air : kotoran ternak = 1,5 : 1. Hasil uji ANOVA dari percobaan perbandingan air : kotoran ternak menunjukkan bahwa perlakuan tidak menunjukkan nilai yang signifikan terhadap konsentrasi CH4, CO2 dan N2O (P>0.05).

Abstract

The performance of a lathe in the turning process is greatly influenced by the components in the lathe itself such as the fixed head, removable head, rotating center, lathe tool, drill chuck and center drill. Reduced lathe performance can cause lathe failure. The incision made by the lathe chisel on the workpiece will determine the result of the turning work. The cylindricity/flatness of the workpiece results from the parallelism of the lathe tool and the workpiece axis. If the lathe tool is not parallel to the workpiece axis, it will produce a workpiece that is oval (not cylindrical) or has an uneven surface. In aligning the lathe tool on the workpiece axis, you must first bring the lathe tool closer to the end of the rotating center, which sometimes takes quite a long time. Laser Auto Level in Lathe Life Center (LAL3C) is a hand tool that functions to make it easier to align the lathe tool on the workpiece axis as an effort to improve the performance of the lathe machine. The research results show that using LAL3C can make it easier to align the lathe tool on the workpiece axis and can shorten the time.

Abstract

  Solid soap as a result from process analysis practicum can be produced using with hot process method using raw material of palm oil and a strong base in the form of NaOH. The aim of this research is that apart from fostering student inquiry regarding the soap making process, they are also able to analyze the parameters of solid soap over a certain period based on variations in the amount of added surfactant. The methods used in practicum activities are dividing practicum groups, making solid soap, and collecting practicum reports. In the activity of making solid soap, the concentration of sodium lauryl sulfate (SLS) was varied for each group, 0, 1, 2 and 3% w/w respectively. The parameters measured in this research were the pH value, water content, ability to form foam, free fatty acid content and ethanol insoluble material in solid soap. The pH characterization of the results of the saponification process shows that soap at all variations in SLS concentration is predominantly alkaline. The characterization carried out showed that the levels of free fatty acids and ethanol insoluble substances met SNI 3532:2016 standards. Water content parameters do not meet these standards because the measurements were carried out during practical activities and without the process of holding the soap product. From the results of observing these parameters, in general it can be concluded that the solid soap products resulting from the practical work have the best quality under the condition of adding SLS with a concentration of 1%.

Abstract

In the electrical energy conversion laboratory, the stable operation of the induction motor is one of the most important factors. Failure of induction motor operation can be fatal in research activities in energy conversion laboratories. Prevention is needed so that the performance of induction motors remains optimal. this paper was created as an alternative for laboratory users of electrical energy conversion in maintaining the performance of induction motors. Based on a survey conducted by the Institute of Electrical and Electronics Engineers (IEEE), the main cause of electric motor operation failure is generally caused by insulation failure, so electric motor testing is generally dominated by insulation testing. Many insulation testing methods such as Insulation Resistance (IR) testing, Polarization Index (PI), Delta tangent, and other tests. In this paper, IR-based testing is proposed, because it is relatively cheap and easy to implement. The IR testing process is carried out using direct voltage from the Insulation Tester to the sample to be tested using the IEEE 43TM-2013 Standard. The test results show the IR value of the sample motor is good. This condition is categorized as safe to operate, so research activities that use induction motors can run well and safely.

Abstract

Kepuasan pelanggan adalah perasaan senang atau tidak senang seseorang yang muncul dari perbandingan antara kesan terhadap kinerja produk dan harapannya. Pengguna tidak puas bila pengguna merasa produk atau pelayanan yang diterima tidak sesuai yang diharapkan. Tujuan penelitian ini adalah untuk mengukur tingkat kepuasan pengguna laboratorium FKM Undip dan mengetahui atribut apa saja yang menjadi ketidakpuasan. Penelitian ini bersifat cross sectional dengan pendekatan kuantitatif. Kepuasan pelanggan mengacu pada metode servqual (servis quality) yaitu penilaian terhadap pelayanan petugas, penilaian terhadap peralatan, bahan dan penilaian terhadap sarana prasarana di laboratorium. Hasil penelitian menunjukkan bahwa pengguna memberikan penilaian sangat puas paling tinggi pada pelayanan petugas yaitu dalam hal penguasaan terhadap alat dan bahan (57,9%). Namun ada pengguna yang memberikan penilaian sangat tidak puas pada keramahan, kesopanan dan sikap dalam pelayanan petugas meskipun jumlahnya sedikit (1,8%). Kesimpulan penelitian ini adalah secara keseluruhan pengguna menyatakan puas terhadap pelayanan laboratorium FKM Undip.
