Implementasi Social Services oleh Pendidikan Tinggi Islam: Studi Kasus IAIN Sulthan Thaha Saifuddin Jambi

The main issue to be explored in this article is how unsignificant a higher education in performing social services activities. The locus of this study is IAIN Sulthan Thaha Saifuddin Jambi. Barriers that occur when conducting social services activities including conceptual and methodological obstacles when implementing community service programs in the field. Conceptually, social services programs simply translated into college students social field work, while the methodology of field work does not bring any new creativity or innovation. Communities demand that the Islamic university to give social services with concrete actions such as guidance for religious teachers, guidance in the management and implementation of zakat and management of mosque, as well as technical assistance in carrying out socio-economic activities.

Hydrophobicity properties of graphite and reduced graphene oxide of the polysulfone (PSf) mixed matrix membrane

Hydrophobicity properties of graphite and reduced graphene oxide (rGO) (from exfoliated graphite/rGO) towards PSf polymer membrane characteristic and properties at different additives weight concentrations (1, 2, 3, 4 and 5 wt. %) were investigated. Both PSF/graphite and PSf/rGO membranes were characterized in term of hydrophobicity, surface bonding, surface roughness and porosity. FTIR peaks revealed that membrane with graphite and reduced graphene oxide nearly diminished their O-H bonding which was opposite to the graphene oxide peak that shows a strong O-H bonding as increased exfoliated times. These results were in line with the contact angle results that showed strong hydrophobicity of graphite and reduced graphene oxide membranes as increased these additives concentration. The effect of strong hydrophobicity in these membranes also has resulted in smoother surface roughness compared to pristine PSf membrane. Further investigation of the performance of water flux also proved that both above membranes have strong hydrophobic effect, with the lowest pure water flux rate (L/m2h) was given by PSf/rGO 3% membrane at 19.2437 L/m2h

Genetic relationships between three indigenous cattle breeds in Mozambique

This study provides the first account of genetic relationships between three indigenous cattle breeds from Mozambique. Forty-two blood group factors and six blood proteins revealed genetic variation of 84% (Angone), 88% (Bovine de Tete) and 90% (Landim) at the loci studied. Average heterozygosity values ranged from 33% for Angone and Bovine de Tete to 35% for the Landim. The genetic distance was greatest between the Landim and both the Bovine de Tete and the Angone breeds, whereas the smallest genetic distance was observed between the Bovine de Tete and the Angone. These results show the intermediate relationship of Bovine de Tete with the Angone and Landim breeds and show that the Bovine de Tete is an admixture of taurine and indicus genes.

Effect of phosphorus and potassium on the growth and yield of French bean

An experiment was conducted at the Agronomy Field Laboratory of the Department of Agronomy, Bangladesh Agricultural University, Mymensingh to investigate the yield response of French bean (Phaseolus vulgaris L.) as affected by phosphorus and potassium management. The experiment consisted of two factors. Factor A: Phosphorus fertilizer (4 levels) viz. P1=15Kg P ha-1, P2=20 Kg P ha-1 and P3=25 Kg P ha-1 , P4=35 Kg P ha-1 and factor B: Potassium fertilizer (4 levels) viz. K1=0 Kg K ha-1, K2=20 Kg K ha-1, K3=30 Kg K ha-1 and K4=40 Kg K ha-1. The variety BARI Jharsheem-3 was used in this experiment as the test crop. The experiment was laid out in a randomized complete block design (RCBD) with three replications. In case of phosphorus @ 25 kg ha-1  the highest number of pods plant-1 (4.96), pod length (13.34 cm), number of seeds pod-1 (4.54), weight of 1000-seed (431.21 g), seed yield (1.33 t ha-1), stover yield (1.53 t ha-1), biological yield (2.86 t ha-1) and harvest index 46.50%  were found. In case of potassium @ 40 kg ha-1, he highest number of pods plant-1 (5.80), pod length (14.89 cm), number of seeds pod-1 (4.24), weight of 1000-seed (430.37 g), seed yield (1.53 t ha-1 ), stover yield (1.46 t ha-1 ), biological yield (2.99 t ha-1) and harvest index 51.17% were found. Interaction effect of phosphorus and potassium the highest  number of pods plant-1 (5.18), pod length (13.40 cm), number of seeds pod-1 (4.30), weight of 1000-seed (430.53 g), seed yield (1.40 t ha-1 ), stover yield (1.60 t ha-1 ), biological yield (3.00 t ha-1 ) and harvest index 46.66% were recorded from P @ 25 kg ha-1 and K @ 40 kg ha-1. However, from the study it can be concluded that application of P @ 25 kg ha-1 and K @ 40 kg ha-1 was the most suitable combination for better yield of French bean

Sustainable waste management via incineration system: an Islamic outlook for conservation of the environment

This paper would firstly examine solid waste management currently experienced in Malaysia with special concentration given to waste incineration. Its function and benefits entailed from this system shall then be identified. This paper attempts to emphasize this notion within the Islamic perspective, stressing on the needs to conserve the environment. This study adopts a qualitative approach where the conceptual authoritative literature in the related field is utilized based on content analysis. The related principles of Islamic jurisprudencecarefully examined along with the Quranic verses depicting on this issue This study further submits that incinerating waste could mitigate environmental impact that might otherwise arise from waste. Finally, it further concludes that Islam provides a concrete model of environmental ethics which is based on divine revelation that needs to be observed.Keywords: sustainable waste management; incineration system; environment conservation;Islamic jurisprudence principles

Generation of Q-switched thulium-doped fiber laser (TDFL) using differentsaturable absorbers

A Q-switched Thulium-doped Fiber Laser (TDFL) operating at approximately 2 µm wavelength is successfully generated by using four different saturable absorbers (SAs) which are nitrogen-doped graphene in PVA (NG:PVA), nitrogen-doped graphene in PEO (NG:PEO), single-walled carbon nanotube in PVA (SWCNT:PVA), and high pressure carbon monoxide carbon nanotube in PVA (CNTHiPCO:PVA). The SAs integrated in the cavity were able to provide the real saturable absorption in modulating the intra-cavity losses. SWCNT gives the best results with the highest repetition rate and lowest pulse width of 57.45 kHz and 1.958 nJ correspondingly as compared to the other three SAs
