Abstract

The implementation of innovative learning and lesson study (LS) are potential to improve student thinking skills and activeness differently and mostly implemented separately. This study aimed to explore and compare the student critical and creative thinking skills as well as student activeness in the inquiry and cooperative models combined with LS-based learning practice. This was a descriptive quantitative study that was conducted at Islamic Senior High School 1 of Bengkulu.  The sample was two classes consisted of 33 and 32 students each that conducted LS-inquiry and LS-cooperative learning. The essay test delivered to measure critical and creative thinking skills and observation sheet to measure student activeness. The data were analyzed by t-test to compare critical and creative thinking skills as well as the student activeness between the LS-inquiry and LS-cooperative classes. The result showed that LS-inquiry learning improved the student critical and creative thinking skills that significantly higher than LS-cooperative learning. The student activeness improved gradually as LS cycles during learning processes in either inquiry or cooperative learning, but no significant difference between these two learning models. It showed that inquiry learning plays a dominant influence in critical and creative thinking skills improvement, whereas LS in student activeness improvement otherwise.

Abstract

Proses sortasi tandan buah segar (TBS) di loading ramp dilakukan oleh operator laki-laki berupa kegiatan menurunkan TBS dari truk, mensortir TBS dan menaikkan TBS mentah ataupun busuk ke truk dengan berat TBS berkisar 20 kg hingga 25 kg dengan menggunakan tojok.  Tojok merupakan sebatang besi berujung tajam dengan pegangan berbentuk T sepanjang 85 cm, diameter batang 2,5 cm dan lebar pegangan 15 cm. Desain tojok aktual menyebabkan operator sortasi memiliki postur tubuh bungkuk,  leher  tunduk, dan lutut tertekuk secara berulang-ulang selama satu hari. Operator mengeluhkan rasa sakit pada otot (MSDs) terutama pada pinggang, lengan atas kanan, punggung, lengan bawah kanan, tangan kanan, dan betis kanan. Keluhan MSDs yang dialami operator semakin meningkat sebanding dengan jumlah truk yang harus dibongkar TBS nya dalam sehari. Metode yang digunakan adalah observasi lapangan dan wawancara dengan kuesioner terhadap operator sortasi sejumlah 8 orang. Penyebaran kuesioner terbuka untuk memperoleh atribut tojok diberikan kepada 30 orang responden. Hasil yang diperoleh adalah tojok  terbuat dari bahan stainless steel, mata tojok terbuat dari besi AS, pegangan berbentuk segitiga, pembatas batang tojok dengan mata tojok berjarak 10 cm dan pegangan  tambahan berjarak 30 cm dari handle. Panjang tojok 97,1 cm, lebar pegangan tojok 11 cm dan diameter batang tojok 2,77 cm. Kata kunci : desain; ergonomis; sortasi; tojok; TBS Abstract Design Analysis of Tojok as Sorting Tools TBS Palm Oil in Loading Ramp. TBS Sorting process in loading ramp, done by male operators,  is the act of bringing down the TBS from the truck, sorting TBS and bringing the raw or rotten TBS back into the truck and the TBS weigh around 20 kg to 25 kg using tojok. Tojok is a steel bar with a sharp end and a handle forming T-shape at the other end that. The dimension is 85 cm long, 2.5 cm in diameter, and 15 cm for handle width. The actual tojok design make the operators to bent their back, flex their kness, and bowed their head for multiple times in a day. Operators are complaining about pain in their muscles (MSDs), especialy in waist, upper arm, back, lower right arm, and right calf. The MSDs pain felt by operators increase as they discharged more TBS from the truck throughout the day. The method used in finding this information is field observation and interview with 8 operators. The result is that tojok is made of stainless steel, its sharp end is made of AS steel, its handle’s shape is triangle, the length from its sharp end to its bar border is 10 cm, and the distance from the handle to another extra handle is 30 cm. The tojok length is 97.1 cm, its handle width is 11 cm, and the diameter is 2.77 cm Keywords:  design; ergonomics; sorting; tojok; TBS

Abstract

The business of making tempe every day processes 50 kg of soybeans into tempeh done manually with 4 craftsmen. But the washing of soybeans is one of the most tiring activities because the crafters have to lift buckets filled with soybeans and water so that the weight of the bucket is quite heavy. The process of washing soybeans starts from the step of pouring 10 kg of soybeans into a bucket, giving water, stirring, lifting the bucket to pouring the water in the bucket. Washing the soybeans until clean is done by the craftsman continuously up to 5 times. Processing 50 kg of soybeans causes the craftsman to carry out the process of washing soybeans 25 times each day. The craftsman complains of back pain and both arms and sometimes the craftsman does not come to work if the pain is unbearable. Utilization of soybean washing tools can reduce the washing time so that the process can be completed more quickly and the crafters do not experience pain complaints. Mechanical soybean washing causes shorter washing time for soybeans, faster work, cleaner soybeans and crafters free from complaints of back pain.

Abstract

Onion chips are foods made from a dough of flour, water and other ingredients that can be easily found in various places, but are generally made manually. Dough making is an activity that requires the longest time and greatly determines the quality of the resulting onion chips. Crafters need a long time, great effort and complaints of pain in several parts of the body due to this activity. This service activity provides a dough sheeting tool to facilitate the work of craftsmen and reduce activity time. The quality of the onion chips produced is getting better and craftsmen are also free from complaints of muscle pain.
