The drying oven functions to reduce the moisture content of raw materials until it reaches a certain moisture content to slow the rate of product damage due to biological and chemical activity. This research aims to design an automatic shoe-drying oven equipped with an LCD screen, exhaust fan, 8-level shelf, and electric heating temperature controller to provide maximum and even heating of leather shoes when gluing and drying leather shoes. Raspberry PI aims to combine and collect production process data in cloud storage in the form of a database, which will then be sent and displayed directly to the operator. The research methodology includes design, manufacturing, assembly, operational testing, performance testing, and evaluation stages. It can be concluded that the research results and progress reports include: (1) The design of the work system and mechanical system for the shoe drying oven can work well. (2) The Raspberry PI Cloud system can collect and display actual drying time data, (3) glue drying temperature of 60°C with a drying time of ±5 minutes, (4) skin heating temperature (texture creation) of 50°C-55°C requires warm-up time ±40 minutes, (5) This machine requires 850 watts of power.

“…Melihat respon lateks saat dicampurkan 50% CaCO3 didapatkan hasil tegangan putus 1,69 N/mm 2 dan perpanjangan putus 648,03% [48] dimana jika hasil MRE Lateks dibandingkan dengan 50% CI particle di dalamnya, didapatkan nilai tegangan putus 4,5 N/mm 2 dan perpanjangan putus 628% yang berarti material MRE Lateks 50% CI particle lebih kuat ikatan silangnya tetapi tidak lebih elastis.…”

Kajian ini membahas MRE Isotropic bermatriks lateks dengan variasi fraksi massa CI particle (wt%) dan mengevaluasi karakteristik yang ditentukan, meliputi densitas, kekerasan, tegangan putus, perpanjangan putus dan swelling dari MRE yang dibuat dengan matrik lateks pekat yang berbeda-beda nilai perbandingan massa antara CI particle dan lateks pekat pada saat pencampuran. Komposisi MRE yang dibuat yaitu 0, 30, 40, 50, 60, 70 wt%, dilakukan di Laboratorium Pusat Penelitan Karet Indonesia yang memiliki alat uji karet yang sudah terstandarisasi untuk pengujian nilai tarik, keras dan swelling di Indonesia. Lateks murni dengan massa jenis 0,94 gr/cm3, terjadi peningkatan lebih dari 100% dengan penambahan CI particle 40%. Peningkatan jumlah CI particle juga meningkatan nilai keras yang semula nilai keras 35 point meningkat 15 point saat penambahan CI particle 70%. Penambahan CI particle menyebabkan penurunan hasil pengujian Tarik, terlihat saat lateks murni memperoleh hasil tegangan tarik 14,5 MPa dan perpanjangan putus mencapai 760%. Saat ditambahkan CI particle 70% tegangan putus menjadi turun mencapai 2 MPa dan perpanjangan putus 610%. Perubahan volume pada saat perendaman dengan larutan ASTM OIL 3 terlihat pada lateks murni yang mengalami penambahan volume 167,94% dan meningkat hampir 100% saat ditambahkan CI particle 70% menjadi 305,97%.
