Abstract

Pigments derived from Penicillium have different toxicities depending on the pigment components. This study was intended to evaluate the sub-acute toxicity of oral exposure of Balb/c mice to Penicillium resticulosum pigment. A total of 50 healthy adult male and female mice were divided into 5 treatment groups and different doses of pigment (0, 125, 250, 500, and 1000 mg kg-1 weight) were orally administered. Oral feeding of pigment with doses 125 to 1000 mg kg-1 body weight daily to adult mice did not cause mortality nor any clinical abnormalities. There were no significant differences in body, liver and kidney weights, nor liver and kidney functions of mice when pigment was given orally with intake doses of 125 to 1000 mg/kg body weight daily for 28 d in comparison to mice without pigment intake (control groups). There is a slight difference in liver histopathology of mice exposed to 500and 1000 mg/kg body weight of pigment for 28 d in comparison to mice control groups, although there were no differences in kidney histopathology. Thus, we can conclude that the pigment of P. resticulosum can be cathegorized as low toxic pigment and well tolerated at dose below 500 mg kg-1 body weight daily for 28 d.

Abstract

Champak (Michelia champaca L.) is a flowering plant in the Magnoliaceae family that requires light as an energy source for photosynthesis. Low light intensity will adversely affected the plant growth. The objective of this study was to determine the effect of various light intensity levels on the growth of champak?s seedlings. It was carried out for three months, February to April 2016, at the Permanent Nursery of BPDAS Palu-Poso, Universitas Tadulako. Randomized Block Design was employed as the method, consisting of five treatments namely: I1 = Light intensity of 10%, I2 = Light intensity of 30%, I3 = Light intensity of 50%, I4 = Light intensity of 70 %, I5 = Light intensity of 90%. Each treatment consisted of two groups, namely Group 1 (seedling with 3-4 leaves) and Group 2 (seedling with 5-6 leaves), which were replicated six times, so there was a total of 60 seedlings as the samples. The parameters were the height, diameter, number of leaves, and leaf area. The results of this study indicated that before the seedlings reached 3-months after weaning, diverse light intensity levels insignificantly affected the observed parameters. Subsequently, it demonstrated the highest level of diameter (1.90 mm), leaf number (3.8 leaves), leaf area (291.01cm2), height (3.83 cm) were obtained by I1, I2, I4, and I5, respectively.

Abstract

The microorganisms found in the forest soil are one of the factors that influence the formation of forest soil. In mountain tropical forests slow down soil formation processes as evapotranspiration decreases, chemical reactions are slower and densities of fungi and soil bacteria are fewer, whereas in lowland forests are rich in vegetation species, as well as hot and humid climate conditions. The purpose of this research is to know the population of fungi and bacteria of forest soil of mountains and lowland forest. The study was conducted from December 2017 to February 2018. This research started from field survey, determination of sampling point. Soil sampling was done on a plot with size 25 m × 25 m with a soil depth of 0-10 cm and composite soil sampling. This research uses descriptive analysis method. The results showed that the population of fungi and bacteria are different between the mountain forest (Nokilalaki) and lowland forest (Kamarora). The lowland forest soil higher of fungi (614 × 103 CFU g-1) and bacteria population (43.6 × 106 CFU g-1) then the mountain forest soil of fungi (188.8 × 103 CFU g-1) and bacteria population (7.36 × 106 CFU g-1).

Abstract

This study aims to determine the vegetative growth of Dendrobium sp orchids at various concentrations of liquid organic fertilizer and fertilizer intensity. This research was designed with a completely randomized design (CRD) factorial pattern. The first factor is the concentration of liquid organic fertilizer consisting of three levels, namely the concentration of 5 ml / liter (A1), 10 ml / liter (A2), 15 ml / liter (A3), and the second factor is the intensity of fertilization consisting of 1 time / week ( B1), 2 times / week (B2), 3 times / week (B3). The results showed that the interaction between the concentration of liquid organic fertilizer and fertilizer intensity significantly affected the time parameters of buds, shoot height, and number of leaves. The 10 ml / liter concentration treatment with fertilizer intensity 3 times / week (A2B3) gave the fastest shoot growth of 7.93 weeks and had the highest yield on Dendrobium sp orchid shoot height at 12 weeks after planting which was 3.5 cm and the amount Dendrobium sp orchid leaves at the end of the observation were 4.75 strands.

Abstract

Penyandang disabilitas berhak untuk mendapatkan pekerjaan yang layak. Pemerintah Indonesia telah mengeluarkan Undang-Undang Nomor 8 Tahun 2016 Tentang Penyandang Disabilitas (UUPD). Pasal 53 ayat (1) UUPD mewajibkan perusahaan Badan Usaha Milik Negara (BUMN) untuk mempekerjakan paling sedikit 2% penyandang disabilitas dari jumlah total pegawainya.Penelitian ini dilakukan untuk melihat tantangan dan peluang dalam pemenuhan hak penyandang disabilitas untuk mendapatkan pekerjaan yang dihadapi oleh pemangku kepentingan dan penyandang disabiltas pada BUMN di Aceh. Penelitian ini menggunakan metode penelitian hukum empiris dengan pendekatan yang bersifat deskriptif analitis. Berdasarkan hasil penelitian diketahui bahwa pemenuhan hak tersebut pada BUMN di Aceh belum terlaksana. Meskipun telah ada Qanun Aceh tentang Ketenagakerjaan dan Peraturan Walikota Banda Aceh Tentang Pemenuhan Hak Penyandang Disabilitas Dalam Mendapatkan Pekerjaan Yang layak, hanya satu dari empat perusahaan BUMN yang menjadi responden yang telah mempekerjakan penyandang disabilitas. Hal ini terjadi karena adanya diskriminasi pada pekerjaan dan posisi tertentu, adanya kesenjangan antara kompetensi dan syarat penerimaan pada lingkungan kerja, dan rendahnya pendidikan dan keterampilan penyandang disabilitas.
