Abstract In this study, we introduce the current situation of the membrane inspection industry. We have developed a new integrated rapid membrane inspection machine (MIM) to test the performances of nanofiltration or ultrafiltration membranes by measuring Silt Density Index (SDI) value (i.e., the key performance indicator) of the water filtered. This study optimizes many key conditions include temperature, pH value and pressures, then establishes an SDI detection new method of ultrafiltration membranes by using MIM. We set the temperature of the test liquid to 25 °C, pH in the range of 7–8, and pressure to approximately 0.10 MPa. The results reflect that MIM can be used to effectively determine the SDI of ultrafiltration membranes used the new method and the results of the method validation are satisfactory.

Fenomena yang diteliti pada UIN Syarif Hidayatullah Jakarta adalah sulitnya melihat capaian kinerja dan pengukuran kinerja. Oleh karena itu, UIN Syarif Hidayatullah Jakarta kesulitan mengambil keputusan dalam manajemen kinerja, sebelum menggunakan IKU, UIN Syarif Hidayatullah Jakarta menggunakan manajemen anggaran dalam penilaian dan pengukuran kinerja. Penelitian ini menggunakan metode kualitatif studi lapangan dengan pendekatan fenomenologi. Yang diteliti adalah pengalaman pola penggunaan Balanced Scorecard (BSC) IKU atau Key Performance Indicator (KPI)  UIN Syarif Hidayatullah Jakarta tahun 2018. Setelah adanya IKU di UIN Syarif Hidayatullah Jakarta dengan menggunakan Balanced Scorecard (BSC). penilaian kinerja dan ukuran kinerja ini bisa sebagai acuan capaiaan kinerja untuk Perangkingan Perguruan Tinggi di tingkat nasional maupun internasional, Laporan Akuntabilitas Kinerja Instansi Pemerintahan (LAKIP), Rencana Strategis (Renstra) dan Rencana Induk Pengembangan Kampus (RIBKA) atau Milestones dengan melihat indikator, target dan ukuran pada lapran tersebut.

DDalam menjalankan fungsi sebagai penilai kinerja pegawai di ITS, Direktorat Sumber Daya Manusia dan Organisasi (DSDMO) ITS masih menggunakan bentuk penilaian Skala Likertz dalam menilai pencapaian terhadap rincian tugas yang dilmiliki oleh pranata komputer. Hal ini memunculkan permasalahan dalam penentuan penilaian kinerja pegawai dalam hal ini pranata komputer yang masih memiliki tingkat subjektif yang tinggi. Hal ini dapat mempengaruhi penilaian kinerja yang diberikan kepada pranata komputer. Untuk mengurangi tingkat subjektif terhadap penilaian kinerja pranata komputer, dibutuhkan sebuah pengukuran kinerja yang berbasis Key Performance Indicator sehingga kinerja dari pranata komputer dapat diukur secara objektif. Selain itu, dibutuhkan sebuah sistem terintegrasi dalam proses pelaporan kinerja pranata komputer agar kinerja dari pranata komputer dapat dipantau secara real-time dan dapat mengetahui tingkat pencapaian kinerja dari pranata komputer.Kata-Kata Kunci: Pranata komputer, Kinerja, Key Performance Indicator, Sistem Pelaporan Kinerja, Dash­board.

Human resources are an important asset in the entire company operations activity. A human resources management support system should be provided to improve performance in  accordance with the company target. The purpose of this study is to design a model of operational and human resource management support systems that can integrate employee performance data, simplify management of employee data, and generate reports in the form of Key Performance Indicator (KPI) and Binusian Level. Methodology used in this study is using literature study, design, and test a model to make operational and human resource management information system. Index Terms - human resources, operational support system, Key Performance Indicator (KPI)

Lime salts in the thin juice obtained after juice purification is one of the most important chemical KPI’s (Key Performance Indicator) in beet processing. Too high lime salts content will significantly affect processing costs – particularly energy – due to scaling of heat exchange surfaces thus decreasing heat transfer. In addition, high lime salts are at the origin of turbidity and insoluble solids in white sugar. Therefore, it is of the utmost importance to understand the chemistry behind lime salts in beet processing in order to be able preventing too high lime salts contents in thin juice. This paper will explain the details of the chemistry behind the presence of lime salts. Further, a trouble-shooting guide is included to elucidate the different causes for high lime salts contents and how these causes can be identified, as well as the process measures to reduce the lime salts content in thin juice.
