Tajak that has been used for hundreds of years by traditional local farmers in South Kalimantan has shownÂ its excellence. It is the appropriate tool to be used on agricultural land that has a typology of swamp land.Â The difficulty of the operation, the amount of power needed to operate and a decline in interest in theÂ younger generation to work in agriculture demanded a call for this tool under research for improvement. ByÂ analyzing the forces acting on tajak, its operational principles will be obtained. This information is useful as aÂ reference for the procedure of t ools utilization in swamp land preparation accordingly with the local wisdom.Â It may promote a correct tajak operation procedure, hence reducing the workload and the number ofÂ occupational accidents, and also important in designing an ergonomic, effective and efficient tajak. In theÂ long run, this research is expected to be the basis for developing tajak as local knowledge -based agriculturalÂ machinery of the Banjarese society in South Kalimantan. The research was conducted following these steps:site selection, land preparation, operator selection, data recording and data processing/analysis. The resultÂ showed that the pattern of tajak operational motion is uniform, with the cutting direction to the left and theoperatorâs left hand plays an important role a s the ârudderâ. Tajak mass and the lift angle affect the magnitudeÂ of force acting on tajak with the maximum force at the minimum axial force. The maximum force experiencedÂ by tajak is at the shaft end and decreases toward the eye.

Abstract Traditional local farmers in South Kalimantan conventionally do the field preparation by using a traditional tool named “tajak”. This typical traditional tool is very appropriate for land preparation in marshland field which is enabling to cultivate without raising the pirit (FeS2) layer. However, it is quite difficult, hard and dangerous to operate tajak, and it’s difficult to learn by a novis operator as well. Therefore, ergonomics study will be beneficial to develop more convenient, safe and effective tajak. The result of workload analysis revealed that tajak operation is an “extremey hard” workload, whichs the avarage of IRHR is 2.14. The workload level of tajak operation is indicatively by workload intencity and swing elevation. Regarding the Total energy cost per weight (TEC’) and hours of work (JOK), the tajak operation consumes 5.36 kcal/kg.hour and need 61.07 hour/ha in average. Anthropometri and motion study analysed revealed that the dimentional suitability of tajak tool is strongly related to shoulders and waist heightly, arms length, and hands grips diameter. Based on the result of tajak anthropometri and motion analyses, for better design of tajak’s handle was recommended 75.70 cm. Keywords: tajak, marshland field, ergonomic, work load, motion analysis, anthropometri Abstrak "Tajak" adalah alat yang lazim digunakan untuk penyiapan lahanoleh umumnya petani padi rawa/lebak tradisional di Kalimantan Selatan. Alat ini sangat tepat dan sesuai untuk penyiapan lahan di area sawah lebak (rawa), di mana diperlukan suatu cara pengolahan dan penyiapan lahan yang tidak mengakibatkan naiknya lapisan pirit (FeS2) ke area perakaran tanaman. Cara penggunaan tajak relatif sulit, berat, dan berbahaya, bagi petani yang sudah berpengalaman sekalipun. Terlebih untuk para pemula, pengoperasian tajak sangat sulit dipelajari. Oleh karena itu, studi ergonomi ini diharapkan dapat bermanfaat untuk mengembangan desain serta cara penggunaan tajak yang lebih aman, nyaman dan efektif. Hasil analisis beban kerja mengindikasikan bahwa pengoperasian tajak tergolong pekerjaan "luar biasa berat", dengan nilai IRHR rata-rata 2.14. Tingginya tingkat beban kerja (IRHR) tersebut sangat ditentukan oleh dua indikator kerja, yaitu intensitas dan tinggi ayunan tajak. Laju konsusmsi energi kerja tajak adalah 5.36 kkal/jam.kg-bb (kilokalori per jam per berat badan operator), sedangkan rata-rata kebutuhan waktu kerja efektif adalah 61.07 jam/ha. Analisis antropometri dan gerak mengindikasikan bahwa tinggi bahu, tinggi pinggang, panjang lengan dan diameter genggaman tangan merupakan parameter terpenting untuk kesesuaian dimensional tajak terhadap operator penggunanya. Sesuai dengan antropometri petani setempat, panjang tangkai tajak ideal yang direkomendasikan adalah 75.70 cm.

Jasmine is a superior floriculture commodity in the Banjar Regency with high economic potential. Local jasmine farmers do not yet have operational standards for jasmine propagation. This study aimed to study various concentrations of Rootone-F with growing media to increase the growth of jasmine cuttings from the Banjar Regency. The experiment used a completely randomized factorial design. The first factor was the concentration of Rootone (a0 = 0, a1 = 100 ppm, a2 = 200 ppm, a3 = 300 ppm, a4 = 400 ppm) and and the second factor is the growing medium (m1 = soil + chicken manure (1:1), m2 = soil + chicken manure + sand (1:1:1), m3 = soil + chicken manure + rice husk (1:1:1), and m4 = soil + chicken manure + burnt rice husk (1:1:1). The results showed that the interaction between Rootone concentration treatment and growing media significantly affected the number of leaves at 8 WAP. Single treatment with Rootone had a significant effect on budding time. Single treatment with growing media had a very significant effect on the time of budding and the percentage of cutting growth. The recommendation obtained from the results of this study is that the provision of 400 ppm Rootone and a growing medium of soil + chicken manure + burnt rice husks can be used to increase the growth of jasmine cuttings. The results obtained from this study can be used to develop a protocol to produce high-quality jasmine planting material through cuttings. Keywords: chicken manure, rice husk, Rootone-F
