Abstract

Lifting, pushing, and pulling activities combined with excessive material load and intense repetition have been reported to trigger excessive pressure on the lumbar disk (L5/S1).  Using a static biomechanical approach (3DSSPP Version 7 software), this study presents empirical evidence proving that log loading activities with manual techniques are jobs that pose a high risk of injury to workers, indicated by (1) very high lifting index value (10), (2) compressive force that exceeds the maximum permissible limit of 6500 N, (3) difficult standing balance control, and (4) high potential of localized musculoskeletal fatigue in the workers.  Musculoskeletal disorders analysis (using the Standardized Nordic Questionnaire instrument) shows intense disturbances in the lower back, shoulders, upper back, and hands.  Interventions to reduce injury to the workers can be carried out by substituting work techniques (using aids devices), improving work administration (improving the standard operating procedure, supervision), and wearing anti-slip work shoes.

Abstract

Most of forestry work has burdened forest workers with heavy workload, which is often exceeding their allowable workload. This workload has been widely measured through energy expenditure-based workload assessment (expressed in kcal/kg/min). However, this calculation method excluded physical characteristic of individual into its calculation, meanwhile it may greatly influenced metabolism system of an individual. Thus, there is a big possibility that the use of kcal/kg/min workload unit in comparing workload among different individuals conducting the same physical work had ended in an erroneous reading.  Therefore, a study on alternative workload measurement that provides a fair assessment when the assessment is conducted among different individuals performing same physical activity is significantly important.  This study proposed an alternative workload calculation approach, in which the workload unit was expressed in %VdotO2max.  The results showed that alternative workload measurement provided excellent accurateness similar to that provided by conventional workload assessment method.  Further analysis showed that  the proposed unit showed a fair reading when the analysis was carried out to more than one individual.  This was because  the proposed unit considered maximum physical work capacity (short term) of each individual in its calculation.

Abstract

Jepara regency is the center for wooden furniture industries in Indonesia, and the products are generally marketed through a number of channels. Observed from the artisan to the last consumers, there were 5 common patterns of marketing channels in Jepara regency.  The structure of the furniture market in Jepara is segmented based on product, quality, and price, therefore this condition has resulted in the monopolistic competition market structure at artisan level and showroom (furniture shops).  Artisans of furniture in Jepara usually get the most orders in July, September, and December. The increase in furniture production was influenced by the religious celebrations of Idul Fitri and Christmas. The survey of furniture shops revealed that most raw materials used by the shops were half-done or unfinished furniture bought from the artisan. The best selling furniture design was elegant design with carved ornaments. In the meantime, the survey result of the households in Jepara which envolved households with permanent, semi-permanent, and non-permanent houses as respondents showed that each type had a different value in the process of searching for information concerning furniture models and places to buy furniture.

Abstract

Teak and mahogany furniture industries in Jepara are dominated by small-scale industrial unit, produce simple type of furniture mostly made from less than 28 cm diameter of teak log.  Timber main producers of the industries are Perum Perhutani and village plantations.  Small-scale furniture industries characterized by limited capital, therefore there is no log stocking behavior. This resulted in a close interaction on log supply and demand dynamics between both traders and industries. As a consequence of drastic increase in the number of the industries, one big question on sustainability of raw material for the industries has been emerged. Data taken from this research indicated scarcity of teak and mahogany log.  Limited capital directs industries to blame the difficulties mainly due to increasing timber price. Additionally, the industries (and log traders) who are stand mostly in level 2 of log distribution chain mentioned that compared to 10 years ago, there is difficulty in obtaining bigger log diameter.  It is a very interesting finding that the industries do not certainly sense timber scarcity as one possibility reason behind the timber scarcity.  As weakness on business resilience has been the main characteristic of the industries, the threads would give a direct impact to the industries soon or later.  To this, serious efforts in maintaining timber sustainability, shortening timber distribution chain, together with capital strengthening seem to be the fastest way in supporting the sustainability of the industries.Keywords: teak furniture, timber price, small-scale, timber scarcity

Abstract

The future of forestry within economic and social activities has to be envisioned and defined, in order to better integrate its multi functionality into education. Only a good definition of the roles played by forestry and the responsibilities future practitioners will carry can help define the curricula and methods. A revision of the current status of forestry science development in Papua New G is given considering its geographical location, market new trends, potential advantages, historical enrollments of students and staff, facilities, and nexus with other institutions. It was found that the forestry department of University of Technology Papua New Guinea has been releasing graduates in the last 36 years with a sub optimal formation, the causes are discussed and possible solutions formulated.

Abstract

Timber harvesting activities are unquestionably related with high risk of work accidents and health disorders.Such activities were not only burdened the workers with heavy physical workloads due to uneasy workingenvironment, and massive work materials and tools, but also physiopsychologically burdened workers as theywere imposed with both mechanical and acoustic vibrations (noise) produced by the chainsaw. However,  it is acommon practice that most of the workers still ignored the importance of the use of noise reduction devices suchas earmuff or ear plug.  This study was aimed to reveal the factual effects of noise on work concentration of theworkers to provide a scientific basis in supporting efforts in improving workers’ attitude.  The results confirmedthat chainsaw might produce noise during operation.  Noise intensities received by both right and left ears werenot significantly different, indicating that left-handed and normal workers received similar degree of noise inboth side of ears. Further, results also showed that there was a significant difference on the perception and workconcentration of chainsaw operators versus sedentary people to the noise.  These findings proved that hearingability of chainsaw operators had declined due to frequent noise exposure.Keywords: timber harvesting, physio-psychological disorder, noise, chainsaw

Abstract

Despite of prevention measures such as government regulations and recommendations through technical and managerial researches, unsafe working practices are still a common practice in Indonesia's forestry work, especially in tree harvesting operation. In order to determine competency level of both field supervisor and workers as a baseline in developing participatory occupational safety and health (OSH) protection program, a previously developed competency assessing instrument has been modified. Further, the redesigned instrument was used to verify competency level of field supervisor and forestry workers (chainsawman, hauling workers, and truck drivers) from 6 different forest sites with similar working method. Results showed that both group of respondents had overestimated their competency level in practical aspect, indicated by the gap existence between OSH self-perception value and the standard-based assessment value. The gap significantly occurred in knowledge, skill, and attitude elements; however working attitudes rest in the worst level. This finding then indicated that improving working attitude should be taken as the goal priority in the OSH protection programs in Indonesia. In short, when the discussion is pointed to practical activities, OSH protection program should adapt such strategies which put serious consideration on control mechanism.

Abstract

Motor-manual logging has been considered as the most dominant logging system in Java Island, Indonesia. The system-which consisted of felling, delimbing, bucking, hauling, and transporting activities- involves a combination of stress factors e.q. difficult work postures, generation of force, and lifting techniques. In the other hand, combination of the three is well associated with high risk of work-related musculoskeletal injuries (MSIs), including musculoskeletal disorders. This research aimed to assess difficult work posture on felling, delimbing, bucking, and manually short wood hauling by employing rapid entire body assessment (REBA) technique and muscular pain scoring based on the worker's perceive. It was revealed that felling and manual hauling were scored 4 in the REBA action level, indicated very high MSIs risk level, and categorized as “necessary now” for an injury risk preventive action. The workers' pain scoring indicated that low back (spine in general) disorders resulting in low back pain has been considered to be the one of the leading safety issues in the felling and manual hauling. Regardless to complex mechanism of how the personal risk and environmental factors associated with manual material handling injuries, job-related factors approach should be underlined in the MSIs prevention initiative in motor-manual logging.

Abstract

Though some scholars argue that Indonesian wood furniture industries are in decline, these industries remain a driving force for regional and national economies. Indonesian wood furniture has a long value chain, including: forest farmers, log traders, artisans, and furniture outlets. In Jepara, Central Java, wood furniture industries contain significant regional and historical importance. Jeparanese wood furniture industries demonstrated great resilience during the economic crisis in the late nineties. Although they were previously able to withstand the pressures of economic crisis, the enactment of Minister of Forestry Regulation (MoFor Reg.) 7/2009 on wood allocation for local use -as one of the implementing regulation of decentralization law 32/2004- causes a potential reduction of wood supply to Jepara. Since September 30th, 2014, however, the constellation of domestic timber politics has changed due to the new decentralization law (23/2014), which shifted most regulations on forest and forest products from the regency to the province. This study evaluates the dynamics of decentralization policy on timber allocation and examines the power of different stakeholders given the changing regulation and its consequences for Jeparanese wood production.

Abstract

This research focused on the possibility to improve the possession of OSH knowledge of Indonesian forestry workers, especially of both supervisor and operators who carried heavy responsibilities as executors of any forestry program. To meet the demand of both respondent groups, a prototype of a board - education game developed in 2015 called "The Felling Safety Games: Supervisor" was up-graded and modified. Data derived from questionnaires, direct observation, in-depth interviews, and logical assumption, provided information on (1) the recent perception of OSH knowledge, (2) the success of the education game implementation, and (3) factors that led to the success of the implementation. The fact that all respondents in this research were overrated on their OSH knowledge reflected serious problems in the field of OSH in the forestry work in Indonesia. It was satisfying to know that the safety game showed a very optimistic result, as the OSH knowledge of the workers were significantly improved after only 2-6 game repetitions. Another factor that led to the success of the implementation of the game was the performance of OSH agent who played a role as facilitator during the game. However, a strong management commitment developed based on a local-based OSH management system, remained as an important requirement for the creation of a safe work behaviour change and healthy workplace.
