Analisis Produksi Dan Pendapatan Pada Izin Usaha Industri Primer Hasil Hutan Kayu (IUIPHHK) Di Kota Palu Studi Kasus Pada PT. Tatehe Nusa Jaya
Full text linkThe objectives of this research were to: (1) know out the effect of production variable factors; raw materials (m³), labor, and production tools of wood processing. (2) to calculate the production income, and (3) to state the feasibility level of PT. Tatehe Nusa Jaya in relation to Timber Product Business Industry License in Palu City. This research was carried out for five months, from February to June 2014. The population was the duration of sawn timber processing activities at PT. Tatehe Nusa Jaya (36 months). The sample was taken monthly. Then sawn timber processing revenue was affected by the fixed costs, variable costs and revenues. Cobb-Douglass analysis production function was used to answer the problem statement of this research. This research uses qualitative descriptive design. The results of production function showed that coefficient determination was 0.828. It means that the model was effective to be applied since the ability to explain the Y factor in the changes of Xi variables (X1, X2, and X3) was 82.8% or high. Meanwhile, the remaining 17.2% was caused by external factors which was not observed in this research. The operating timber product business industry revenues of PT. Tatehe Nusa Jaya was profitable. The company's revenue was Rp. 31.772.648.018,-. Variable production factors influence the increase in operating revenues IUIPHHK PT. Tatehe Nusa Jaya. This high revenues was taken from the small ratio of total production cost in comparison to the total income. Thus economically good to run because the value of the level of feasibility is Rp. 13.74 and because the value of the RC ratio> 1. It means that the feasibility of company was 1: 13,74
Studi Populasi Dan Habitat Anoa (Bubalus sp) di Kawasan Hutan Lindung Desa Sangginora Kabupaten Poso
Full text linkThe research objective is to estimate and study the genaral picture of dwarf buffalo (Bubalus sp) in oder that their presence around can still be recorded and better managed in Sulawesi. Descriptive research method was used by applying line transect to observe population quadrat transect was used to analyze habitat composition. Based on footprints found, there were estimated that were about less that 12 adult, 8 teenagers and 5 young dwarf buffaloes around within 13 obrvation points with density of 1.23 dwarf buffaloes/km2 or around 1 – 2 per square kilometres. For habitat vegetaton, there were about 85 species function as supporting habitat and about 33 species as food sources. Laboratory analysis noted that soil texture on the sites are clay with salinity level of 0.72 µS/cm. In addition, it was recorded that the temperature during the morning time were about 140 C – 180 C, 180 C – 200 C during the noon time, and arond 200 C – 150 C during the evening time. To summarize, the population sze of dwarf buffalo can be conculded as low leading to extinction if illegal hunting and habitat destruction continuously occur
Perkecambahan Dan Pertumbuhan Benih Pala(Myristica fragrans Houtt) Akibat Lama Perendaman Pada Atonik Dan Komposisi Media Tanam
Full text linkThis research aimed at determining the process of germination and growth of nutmeg seeds to obtain superior nutmeg seeds in Baolan Sub District of Tolitoli District. The research was conducted in two stages of experiments. The first stage involved soaking the seeds under different periods including with no soaking (A0), two hour soaking period (A1) and three hour soaking period (A2). This experiment used a Completely Randomized Design where each treatment had seven replicates. Greatest germination rate of 34.29% was found in the three hour soaking period after the seeds were allowed to sproud for six weeks. This was significantly different from the other two treatments under which treatments the germination rate was only 26.43%. At the second stage, the soaking period treatments were combined with various growing media including T1 (soil:sand:cow manure bokashi; v/v/v), T2 (soil:sand:cow manure bokashi; v/v/2v), and T3 (soil:sand:cow manure bokashi; v/v/3v) . The experiment was arranged in a Two Factorial Randomized Block Design where each treatments had four replicates. The average seedling height of 18.85 cm found in the A2T3 treatment 12 weeks after planting (WAP) was significantly higher than in the A1T2 and A0T1 under which treatments the heights were only 14.45 cm and 12.77 cm, respectively
