Abstract This study aims to determine the production of oil palm with a different replanting system. The study was conducted in the area of simultaneous fallen replanting system and underplanting system area located in Panca Mulya Village, Sungai Bahar District, Muaro Jambi Regency. The material used in this study was the Tenera variety of oil palm plants aged 4.5 years and 5.5 years. The study used a survey method with systematic sampling method. The main variables observed were plant production as well as physical plant additional variables, soil pH, light intensity, temperature, and humidity. The results showed that the replanting system significantly affected the production of oil palm plants and plant physicality, soil pH, light intensity, temperature, and air humidity. Palm oil crop production is higher in areas with simultaneous fallen replanting systems. Key words: replanting system, oil palm

Bamboo belongs to the Gramineae family (grasses) also called Giant Grass. Bamboos live in clumps, consisting of a number of stems (reeds) that grow gradually, starting from bamboo shoots, young and adult stems at the age of 4-6 years. The stem of this plant is cylindrical, sectioned, segmented, occasionally having massive hollow, hard-walled, in each section there are buds or branches. This study aims to find out the type and to identify the type of bamboo that is in the Tembawang Deret Jat Forest of Peruan Dalam Village in the District of Tayan Hulu, Sanggau Regency. This research will be carried out with a survey method using sampling techniques in a systematic sampling method in the form of making paths. The path used is not determined by the number of lines with a width of 20 meters and the length of the path is not determined and the distance between the lines is 50 meters. In the area of Tembawang Deret Jat Forest of Peruan Dalam Village in Tayan Hulu Subdistrict, 7 types of bamboo were found, namely Gigantochloa robusta, Gigantochloa balui, Schizostachyum zollingeri, Schizostachyum sp, Dendrocalamus asper, Schizostachyum brachycladum, Schizostachyum silicatum, and 3 bamboo genera Dendrocalamus, Gigantochloa, Schizostachyum, Schizostachyum, Schizostachyum and one Poace family.Keywords : Bamboo, Bamboo shoots, Clump, Reed, Tembawang forest.

Nyabah, or Jabah (Pinanga arinasae J.R.Witono) is pinanga or palm which is endemic to Bali.  This study aimed to determine the distribution, abundance patterns, and habitat preferences of P. arinasae, and also its natural microclimate on Mount Pengelengan, Bali, on which the species occurred. Field observations were conducted using systematic sampling method. 20 x 20 m plots were made along a transect of forest path on the right and the left, with 100 m distance between plots. Results showed P. arinasae distribution in Mount Pengelengan grows clumped with different abundance in each plot. Microclimate observations (light intensity, humidity relative, and air temperature) each plot varies the effect on the distribution and abundance of P. arinasae. Light intensity is the main factor that regulates the abundance and distribution of P. arinasae and this species has the most abundant on the limited canopy cover area which has high the light intensity at 1319 lux. Autecological data is the first step in conservation efforts.

Arrangement of planting spacing with a certain density aims to give a plant area for each grow well. Planting spacing will affect its density and efficiency useness of light, water and nutrients using competition among the plants so finally it will affect its production. This study purposed  to determine the productivity of cocoa plants at different planting space. The research had been carried out in the community cocoa farming in Betung Village, Kumpeh Muaro Jambi District, Jambi Province, in March - April 2019. Cacao on Ten-year-old Lindak varieties were planted in a farm with plant spacing in  long and wide as 4,2 x 4,5 m (L1) and 5,5 x 6,0 m (L2). Systematic sampling method was applied and the observed variables were wet and dry seed weight, productivity, plant height, soil acidity, air temperature and humidity. The results showed that cocoa  planted in  long and wide as  5,5 x 6,0 m (L2)  gave better on both wet seed produced and dry beans productivity than those planted at  4,2 x 4,5 m (L1). The air humidity at 4,2 x  4,5 m (L1) was higher than in 5,5 x  6,0 m (L2).Keywords: cocoa, spacing, productivity AbstrakPengaturan jarak tanam dengan kepadatan tertentu bertujuan memberi ruang tumbuh pada tiap-tiap tanaman agar tumbuh dengan baik.

In this study, five abattoirs in Istanbul were visited between January 2000 and April 2001. During these visits, 330 cattle were selected by a systematic sampling method. Cattle were examined clinically and breed, age, and sex were recorded. Rectal swabs were taken immediately after slaughter. Immunomagnetic separation was performed, and sorbitol-negative colonies were selected on sorbitol MacConkey agar with cefixime and tellurite (CT-SMAC agar). These colonies were checked for 4-methylenebelliferyl-β-d-glucuronide, indol, rhamnose, and urease activity and motility. Serotypes of bacteria were determined by using antisera specific for Escherichia coli O157 and H7. All cattle selected were clinically healthy. Of 88 sorbitol-negative colonies selected on CT-SMAC agar, isolates from only 14 (4.2%) cattle reacted with anti-O157, and 13 of these isolates also reacted with anti-H7. E. coli O157:H7 was isolated from all breeds, but the numbers of isolates were largest for Holstein and Swiss Brown cows. E. coli O157:H7 was most frequently isolated from 2-year-old cattle. Similarly, it was most frequently isolated from male cattle. E. coli O157:H7 was isolated from cattle slaughtered in four of the five abattoirs studied.

The background of this research was based on the continued development of international aviation in the world which was a challenge for the translator to find an equivalent sentence. The purpose of this thesis was to find the equivalence type used in translating the source language to the target language and find the dominant equivalence type used. For solving this problem, the writer used Nida and Taber theory that divided equivalence types into two types, namely formal equivalence or formal correspondence and dynamic equivalence. The method used was descriptive qualitative method. The data was obtained through systematic sampling method. Based on the analysis, the equivalence types of 53 of 66 samples (80%) were translated by using formal correspondence; 12 of 66 samples were translated using dynamic equivalence (18%) and only one sample (2%) did not neither involve in formal correspondence nor dynamic equivalence because SL text did not have translation in TL (reserved). The most dominant equivalence type used in the translation was formal correspondence.

Abstract Krueng Raya waters is an area that has a distribution of coral reef ecosystems. This study aims to determine the recruitment of hard corals after coral bleaching Krueng Raya waters, Aceh Besar District. This research was conducted in April 2017 in Krueng Raya, Aceh Besar. Data were collected at three observation stations using a systematic sampling method using a 1x1 m quadratic transect. Based on the study results, coral recruitment was obtained from eight families and 13 genera (Acropora, Cetenactis, Diploastrea, Favia, Favites, Galaxea, Goniastrea, Helliopora, Leptastrea, Montastrea, Pavona, Pocillopora, and Porites). Where the most abundant coral genus found was from the genus Pocilopora and Porites (16 coloni/10m2). while the station with the highest colony abundance was at station 3 with 28 colonies/10m2.

Musculoskeletal Disorders (MSDs) is a label for the perception of pain or pain in the musculoskeletal system. MSDs can be caused by the equipment, techniques, and activities performed during work. Harvesters who use manual techniques or cutting egrek have the potential risk for MSDs as a result of an ergonomic work attitude and posture. This study aims to determine the profile of oil palm harvesters using cutting egrek techniques. This research is a descriptive research with the survey method. Samples were obtained by systematic random sampling method, amounting to 82 people. The data used in this study are primary data and secondary data. Most CuE technique oil palm harvesters were at the age of 41-50 years, working period of 6-10 years, and with a work posture that needed immediate improvement, and 76.8% suffered from MSDs complaints. So that it is necessary to have immediate intervention from companies and workers to reduce the risk of MSDs complaints in the future, especially in posture and work techniques.
