Hubungan Motivasi dan Kepuasan Kerja terhadap Kinerja Penyuluh Kehutanan
Full text linkThis research aims to describe and analyze the profile, level of motivation, job satisfaction and performance of forestry instructors at the Lore Lindu National Park Office (LLNPO). The research results show that the profile of forestry instructors is "young" (under 30 years), and has relatively recent work experience. Currently, their work experience is generally less than 10 years. However, formally the level of education is "high" (bachelor's degree). Motivation and level of job satisfaction of forestry instructors are classified as "good". This means that forestry instructors are satisfied with their work and performance as forestry instructors. The results of the analysis also show that the performance level of forestry instructors is in the "medium" category. However, forestry instructors do not fully understand the planned activities so they cannot be implemented optimally. This can affect the fulfillment of the credit score that will be submitted as a condition for promotion. Based on the results of the correlation analysis, it shows that there is no significant relationship between the profile and job satisfaction of forestry instructors and their performance, but there is a real relationship between the work motivation of forestry instructors and their performance

No full textThe aim of this research is to identify the diversity of bacterial types and determine the prevalence value of these bacteria on the carapace of C. amboniensis from natural habitats to support the provision of data that can later be used to support captive management activities and conservation actions C. amboniensis was collected manually and 20 individuals were obtained, samples were caught in December 2019. Data from bacterial identification was then used to calculate the prevalence of bacterial diversity. The identification results showed that there were 7 types of bacteria, most of which were Gram negative bacteria. The prevalence values were then calculated to obtain the results of A. caviae (5%), C. jejuni (30%), C. freundii (15%). ), F. breve (25%), L. monocytogenes (15%), P. haemolytica type A (5%), and P. alcaligenes (5%).The aim of this research is to identify the diversity of bacterial types and determine the prevalence value of these bacteria on the carapace of C. amboniensis from natural habitats to support the provision of data that can later be used to support captive management activities and conservation actions C. amboniensis was collected manually and 20 individuals were obtained, samples were caught in December 2019.

Pengaruh Kedalaman Lubang Tetas terhadap Daya Tetas dan Waktu Inkubasi Telur Maleo
Full text linkThis research aims to determine the appropriate depth of the hatching hole in order to increase hatchability and shorten the incubation time for Maleo eggs. The research design used a Completely Randomized Design (CRD) with 4 hatching tests with depths: K1 (40 cm), 50 cm, 60 and 70 cm with 5 repetitions. The variables observed consisted of hatching hole temperature, hatching humidity, incubation time and hatchability. Data were analyzed using SPSS Version 2.1. Anova results showed that the treatment had a high significant effect (P<0.01) on hatch hole temperature and hatch hole humidity. The conclusion from the results of this research is that the treatment that provides the shortest hatching time and the highest hatchability is the K3 treatment (60cm depth) with an average hatching temperature of 33.40 0C (range 33-34 0C) and an average hatching humidity of 62.40% (range 60 – 74%), in the Maleo Saluki Population Development Demonstration TNLL because it is capable of hatching up to 100% with an average incubation time of 69 days (range 65 – 74 days)
Physiological Responses of Local Goat Fed by Green Concentrate
Full text linkThis research aims to determine the physiological response of local goats fed green concentrates in the form of Indigofera zollingeriana, Sesbania grandiflora and Gliricidiasepium. This research used a Completely Randomized Factorial Design with the first factor being 3 types of nuts and the second factor being 3 treatment levels (60%, 70% and 80%). The results of the study showed that body weight gain and efficiency of forage use for goats fed Gamal Green Concentrate were significantly lower than Turi and Tarum Green concentrates, however consumption of local dry goat content gave the same results. However, based on statistical tests, goats fed green concentrate had no significant effect on the status of goat physiology. The body temperature of local goats given 80% green concentrate was higher compared to 60% green concentrate and 70% green concentrate. The pulse frequency and respiratory frequency of local goats given 60% green concentrate were higher compared to 70% green concentrate and 80% green concentrate. However, based on statistical tests, goats fed green concentrate had no significant effect on the status of goat physiology.Penelitian ini bertujuan untuk mengetahui respon fisiologis kambing lokal yang diberi Green concentrate berupa Indigofera zollingeriana, Sesbania grandiflora dan Gliricidia sepium. Penelitian ini menggunakan analisis Rancangan Acak Lengkap (RAL) pola faktorial dengan faktor pertama yaitu tiga jenis leguminosa (Green concentrate Tarum, Green concentrate Turi dan Green concentrate Gamal) dan faktor kedua yaitu tiga level perlakuan (60%, 70% dan 80%). Setiap perlakuan akan diulang sebanyak empat kali. Peubah yang diamati dalam penelitian ini adalah pertambahan bobot badan, konsumsi bahan kering pakan, efisiensi penggunaan ransum, suhu tubuh kambing, frekuensi pulsus dan frekuensi respirasi. Hasil penelitian menunjukkan bahwa pertambahan bobot badan dan efisiensi penggunaan pakan kambing yang diberi green concentrate berbahan dasar gamal nyata lebih rendah dibanding green concentrate berbahan dasar Turi (Sesbania grandiflora) dan Tarum (Indigofera zolingeriana), sedangkan konsumsi pakan memberikan hasil yang sama. Level pemberian tepung daun dalam green concentrate memberi pengaruh nyata terhadap pertambahan bobot badan dan efisiensi penggunaan pakan. Pertambahan bobot badan kambing lokal yang diberi green concentrate dengan level 60% nyata lebih rendah dibanding green concentrate dengan level tepung daun sebesar 70% dan 80%, sedangkan konsumsi pakan memberikan hasil yang sama. Suhu tubuh dan frekuensi respirasi kambing lokal yang diberi green concentrate turi memberikan rataan tertinggi dibandingkan green concentrate gamal dan juga green concentrate tarum dengan rataan suhu tubuh sebesar 38,84oC dan rataan frekuensi respirasi sebanyak 37,21 kali/menit. Frekuensi pulsus kambing lokal yang diberi green concentrate tarum memberikan hasil rataan tertinggi yaitu sebanyak 85 kali/menit. Tetapi berdasarkan hasil uji Anova, pemberian green concentrate tidak berpengaruh nyata terhadap status faali kambing lokal. Suhu tubuh kambing lokal yang diberi green concentrate dengan level 80% memberikan rataan tertinggi dibandingkan green concentrate 70% dan juga green concentrate 60%. Frekuensi pulsus dan frekuensi respirasi kambing lokal yang diberi green concentrate 60% memberikan hasil rataan tertinggi dibandingkan green concentrate 70% dan 80%. Tetapi berdasarkan hasil uji Anova, pemberian green concentrate tidak berpengaruh nyata terhadap status faali kambing lokal
Biomassa dan Cadangan Karbon Tegakan Kemiri (Aleurites moluccana Willd)
Full text linkThis research was conducted to determine the biomass and carbon reserves of candlenut stands (Aleurites moluccana Willd), determine the effect of stand age on increasing biomass and carbon reserves, see the level of soil health and determine the relationship between stands. This type of research is descriptive which was carried out through surveys and data analysis using SPSS. The research results show that stand age has a positive effect on the amount of biomass and carbon stock produced. In 6 year old stands the average biomass = 12.23 tonnes/ha, and carbon 5.72 tonnes/ha, in 10 year old stands the average biomass = 23.23 tonnes/ha and carbon 10.87 tonnes/ha, 15 year old stands had an average biomass = 35.07 tons/ha and carbon 16.45 tons/ha. The correlation between age and biomass obtained by the equation The higher the age, the larger the stand diameter so that more biomass and carbon are produced. In addition, the high content of c-organics in the soil can maintain soil health levels
