Abstract

The proofing process is an essential step in bread-making, where the dough is allowed to rest for the gas content to develop and form a soft structure. However, many small-scale bread producers still rely on manual methods for proofing, leading to unstable temperature and humidity levels and longer production times. This study focuses on developing an electrical system for a bread proofer that can stabilize temperature and humidity during the proofing process. The system includes an Arduino Mega microcontroller with a DHT22 sensor for real-time temperature and humidity detection, an I2C LCD for monitoring, and a potentiometer for setting the desired temperature and humidity values. To achieve stability, a PID control system is used. The results show that the system can stabilize at a temperature of 40.10oC and humidity at 80-90RH for approximately 38.4 minutes. This electrical system offers an effective solution for optimizing the proofing process in bread production.

Abstract

Company X is a paving block molding machine fabrication company in Surabaya. However, the machine still has some shortcomings because it is still conventional or manually operated. Some of these shortcomings, such as being still prone to human error and being less consistent when operating, can affect the results of the amount of production. From this phenomenon, automation is very important in the industrial world. Therefore, by referring to previous phenomenon, through this research, an automatic control system is made on paving block molding machine using PLC. The results showed that PLC succeeded in developing a system that works automatically on the machine. Then, the ladder diagram used several instructions, including interlock, timer, counter, and set reset according to how the machine works. Then, the PLC-based automatic control system has a shorter cycle time than the original manual machine. Cycle time has decreased by 15.4%. From this decrease in cycle time, if simulated related to production capacity, an automatic control system can increase the production per hour by 300 pcs more than the manually operated machine.

Abstract

Daun sungkai (Peronema canescens Jack.) meruapakan tumbuhan yang dikenal memiliki berbagai manfaat farmakologis, termasuk sebagai antiinflamasi, antimikroba, dan antioksidan.  Tumbuhan ini mengandung senyawa fenolik, flavonoid, tanin, dan saponin yang dapat berperan seabagai antioksidan. Berkaitan dengan hal tersebut, penelitian ini bertujuan untuk menganalisis profil fitokimia dengan GC-MS. Selain itu, juga akan membuktikan aktivitas antioksidan ekstrak daun sungkai dalam menhambat kerusakan membran eritorit akibat pajanan sinar UV. Daun Sungkai diperoleh dari KHDTK Mandiangin diektrak dengan pelarut methanol dengan metode maserasi. Hasil ektrak dilakukan uji GC-MS dan uji penghambatan kerusakan eritrosit akibat sinar UV. Pengujian terdiri atas 2 kelompok, yani 2 kelompok control dan 3 kelompok perlakuan. Kelompok perlakuan menggunakan ektrak metanol daun sungkai masing-masing 10 ppm, 15 ppm, dan 25 ppm. Sementara itu, pemajanan eritrosit dilakukan selama 2 jam. Hasil penelitian ini dapat disimpulkan bahwa berdasarkan  analisis GC MS menunjukkan bahwa ekstrak metanol daun sungkai mengandung senyawa 4-Metoksi-3-trimetilsilil)metil-1-oktena, D-Limonen, Asam tridekanoat, 12-cis-oktadekanoat, asam 13-oktadesenoat, metil ester, asam oleat, dan Glisidil (Z) -9-heptadekanoat yang dapat mengurangi kerusakan eritrosit akibat paparan sinar UV. Selain itu, ektrak metanol daun sungkai dapat menghambat kerusakan membrane eritrosit yang ditandai oleh penurunan %Hb dan kadar MDA pada kelompok yang diberikan ekstrak methanol daun insulin. Kata Kunci: Pajaanan UV, antioksidan, Daun Sungkai, Membrane Eritrosit, Peroksidasi Lipid Sungkai leaf (Peronema canescens Jack.) is a plant known to have various pharmacological benefits, including as anti-inflammatory, antimicrobial, and antioxidant. This plant contains phenolic compounds, flavonoids, tannins, and saponins that can act as antioxidants. In this regard, this study aims to analyze the phytochemical profile by GC-MS. In addition, it will also prove the antioxidant activity of sungkai leaf extract in inhibiting erythrocyte membrane damage due to UV exposure. Sungkai leaves obtained from KHDTK Mandiangin were extracted with methanol solvent by maceration method. The extracts were subjected to GC-MS test and UV light-induced erythrocyte damage inhibition test. The test consisted of 2 groups, 2 control groups and 3 treatment groups. The treatment groups used methanol extract of sungkai leaves at 10 ppm, 15 ppm, and 25 ppm, respectively. Meanwhile, erythrocyte exposure was carried out for 2 hours. The results of this study can be concluded that based on GC MS analysis shows that the methanol extract of sungkai leaves contains compounds 4-Methoxy-3-trimethylsilyl)methyl-1-octene, D-Limonen, Tridecanoic acid, 12-cis-octadecanoic, 13-octadesenoic acid, methyl ester, oleic acid, and Glycidyl (Z)-9-heptadecanoic which can reduce erythrocyte damage due to UV exposure. In addition, sungkai leaf methanol extract can inhibit erythrocyte membrane damage characterized by a decrease in %Hb and MDA levels in the group given insulin leaf methanol extract.

Abstract

Kajian terhadap sastra Madura modern ini menggunakan pendekatan studi kultural (cultural studies). Tujuannya untuk menggali identitas, karakter, dan warna lokal Madura dalam karya sastra yang ditulis generasi kiwari. Teks dalam sastra Madura modern menyimpan sebuah transisi diskursif sepanjang sejarah kemunculan karya tersebut dan kultur masyarakatnya. Karya tersebut memiliki beragam cara pandang dan mode deskripsi terhadap lokalitasnya, baik itu yang berupa ruang budaya, manusia, ingatan kolektif, konflik komunal maupun aspek kemanusiaan dengan segala pergulatannya. Dalam karya itu, terdapat pembacaan pada kekhasan identitas dan lokalitasMadura, baik itu yang hablur dalam kultur maupun tersengal di ranah sosial. Identitas itu tidak statis.
