Gula aren diperoleh dari nira hasil sadapan pohon aren  dan  merupakan  salah  satu bahan baku dari pembuatan makanan maupun minuman.  Pembuatan  gula aren  yang  ada   di  Desa Tanggari Minahasa Utara Sulawesi  Utara  menggunakan bahan bakuair nira (saguer), akan tetapi pada  proses  pembuatan  gula  aren masih tradisional dengan menggunakan sepenuhnya tenaga manusia. Penelitian ini bertujuan untuk membuat  prototype  alat pengolah   gula   aren dengan menggunakan kontrol  Programable  Logic  Controler  (PLC) dan monitoring  Human   Machine   Interface   (HMI), dilengkapi   dengan   sensor  thermostat   sebagai alat pengukur temperatur  pada  saat  proses  pemasakan   air   nira dengan   gas   LPG   dan motor   wiper sebagai penggerak alat pengaduk. Hasil pengujian yang dilakukan untuk air nira 3 liter dengan suhu ± 100 0C diperoleh gula aren 750 gram. Dengan menggunakan kontrol PLC dan monitoring HMI pada alat pengolah gula aren ini diharapkan dapat meringankan tenaga pekerja   dan   mempercepat   proses   pengadukan   gula  aren sampai mengental sehingga   pada   akhirnya dapat meningkatkan efisiensi produksi.Palm sugar is obtained from the sap of palm tree tapping and is one of the raw materials for making food and drinks. The manufacture of palm sugar in the village of TanggariMinahasa Utara, North Sulawesi, uses sap (saguer) as the raw material, but the process of making palm sugar is still traditional, using full human power. This study aims to make a prototype of a palm sugar processing tool using Programable Logic Controler (PLC) control and Human Machine Interface (HMI) monitoring, equipped with a thermostat sensor as a temperature measuring device during the process of cooking sap water with LPG gas and a wiper motor as a driving force. mixer.From the results of tests carried out for 3 liters of sap water with a temperature of ± 100 0C, 750 grams of palm sugar was obtained.Using PLC control and HMI monitoring on the palm sugar processing equipment is expected to relieve labor and speed up the process of stirring the palm sugar until it thickens so that in the end it can increase production efficiency.

The purpose of this research is to develop teaching materials to read English for special purposes ESP Informatics Englishbased multimedia in students of informatics at the Department of Electrical Engineering Manado State Polytechnic. This study uses research and development (Research and Development) with stage design, and development of the steps: identification, exploration, realization context, the realization of pedagogical and physical products, while at the stage of evaluation of the measures expert testing and development class , Analysis of measurement data is done by means of qualitative and quantitative. Data on field test results on the effectiveness of the design is processed using a t-test. The measurement results show that an increase in student reading comprehension of the material presented. The results of this study are expected to be used by faculty and students who teach and learn English at Informatics program at the Polytechnic of Manado.
