Judul: Workload analysis on tea manual picking activities at gunung mas plantation of  pt. Perkebunan Nusantara VIII, Cisarua, Bogor, West Java
Abstrak: Tea (Camellia sinensis) is one of important commodities in West Java since 1860. Activities of tea cultivation include nurseries, land preparation, planting, plant maintenance, and tea picking. Generally, tea picking is done manually by hand. This work is quite heavy and burdensome to the ability of the worker, so that it can lead to fatigue or physical disorder. Workload analysis in tea picking were conducted by using heart rate analysis approach. Then, the value of qualitative and quantitative workload will be obtained. Four male and four female subjects were observed and measurement of heart rate were conducted to them by using “wrist-watch type” Heart Rate Monitor (HRM). A step test protocol was conducted to each subject as heart rate calibration procedure prior to the workload analysis of the tea picking activity. Work productivity of the subjects were also analyzed based on “yield and its quality index”. The results, revealed that the tea picking activity is light to moderate work burden, whereas the average work burden of male is slightly higher than that of female. Regarding to the work energy cost, male subjects consume slightly higher energy compared to that female subjects to pick a same amount of yield. Generally,the net product of male workers are higher than that of female.

Judul: Management of Tea Tree Plucking (Camellia sinensis (L.) O. Kuntze) at Wonosari Estate, PT Perkebunan Nusantara XII, Malang
Abstrak: Pemetikan merupakan kegiatan pemanenan pucuk dan daun teh yang dapat mempengaruhi kualitas dan kuantitas pucuk teh. Kegiatan magang dilaksanakan pada bulan Februari – Juni 2022 di PT Perkebunan Nusantara XII. Tujuan kegiatan magang adalah meningkatkan pengetahuan, keterampilan, pengalaman kerja secara teknis di lapangan dan manajerial pada perkebunan teh, serta mengetahui dan memahami pengelolaan pemetikan terhadap hasil pucuk teh dengan mutu yang baik dan produksi yang tinggi. Metode yang digunakan adalah metode langsung dan tidak langsung. Hasil pengamatan tinggi bidang petik dan lebar bidang petik menunjukkan hasil berbanding lurus dengan umur pangkas, bertambahnya umur pangkas maka tinggi bidang petik dan diameter bidang petik lebih besar. Perkembangan pucuk pada pemetikan manual lebih cepat, persentase pucuk peko menurun dengan bertambahnya umur pangkas. Hanca dan gilir petik pada pemetikan manual lebih kecil. Analisis petik pada pemetikan manual lebih baik untuk memperoleh jenis petikan medium. Analisis pucuk yang memenuhi syarat (MS) pada pemetikan manual lebih tinggi dibandingkan pemetikan mesin. Tenaga pemetik di lapang dari metode manual dan mesin masih kurang. Kapasitas pemetik pada metode pemetikan mesin lebih besar. Kapasitas pemetik dapat dipengaruhi oleh umur, lama pengalaman kerja, dan gender., Picking is an activity of harvesting tea shoots and leaves that can affect the quality and quantity of tea shoots. Internship activities are carried out in February – June 2022 at PT Perkebunan Nusantara XII. The purpose of the internship is to increase knowledge, skills, technical and managerial work experience in tea plantations, as well as to know and understand the management of picking tea shoots with good quality and high production. The method used is a direct and indirect method. The results of observations of the height of the picking field and the width of the picking field show that the results are directly proportional to the age of the pruning, increasing age of the pruning means that the height of the picking field and the diameter of the picking field are larger. Shoot development in manual picking was faster, the percentage of peko shoots decreased with increasing pruning age. Chopping and rotating picks in manual picking is smaller. Pick analysis on manual plucking is better for obtaining medium plucking types. Analysis of eligible shoots (MS) in manual picking is higher than that of machine picking. Picking power in the field from manual and machine methods is still lacking. The picking capacity of the machine picking method is greater. Picking capacity can be influenced by age, length of work experience, and gender.
