Potential Development of Liquid Smoke From Oil Palm Solid Waste as Biofungicides

This research investigated the potential utilization of solid waste from palm oil industry for liquid smoke production in Aceh Province, Indonesia. The liquid smoke can be applied as bio fungicides in agricultural field. Preliminary experiment on the use of liquid smoke as fungicide at Colletotrichum capsisi fungus which causes anthracnose disease on red pepper was also conducted. The survey on the existing potential/availability of palm oil mill in Aceh shows that there are 30 palm oil mills in eight districts with a total of production capacity 1020 ton/hour. Assuming that 10% of palm oil kernel shells are pyrolized into liquid smoke, Aceh province could produce about 23,868 ton of liquid smoke per year. The preliminary test result towards Colletotrichum capsisi fungus shows that the liquid smoke can be used as fungicides

Planting Jatropha curcas on Constrained Land: Emission and Effects from Land Use Change

A study was carried out to assess carbon emission and carbon loss caused from land use change (LUC) of converting a wasteland into a Jatropha curcas plantation. The study was conducted for 12 months at a newly established Jatropha curcas plantation in Port Dickson, Malaysia. Assessments of soil carbon dioxide (CO2) flux, changes of soil total carbon and plant biomass loss and growth were made on the wasteland and on the established plantation to determine the effects of land preparation (i.e., tilling) and removal of the wasteland's native vegetation. Overall soil CO2 flux showed no significant difference (P < 0.05) between the two plots while no significant changes (P < 0.05) on soil total carbon at both plots were detected. It took 1.5 years for the growth of Jatropha curcas to recover the biomass carbon stock lost during land conversion. As far as the present study is concerned, converting wasteland to Jatropha curcas showed no adverse effects on the loss of carbon from soil and biomass and did not exacerbate soil respiration

Pengaruh Dosis Pupuk N, P, K Dan Pupuk Kandang Sapi Terhadappertumbuhan Dan Hasil Wijen (Sesamum Indicum L.)

Tanaman wijen ialah salah satu tanaman penghasil minyak nabati yang mempunyai potensi agroindustri cerah khususnya aneka industri dan minyak makan (Mardjono, et al., 2007). Produksi wijen di Indonesia hanya 2.500 ton per tahun, sedangkan kebutuhan konsumsi dalam negeri mencapai 4.500 ton per tahun. Hal tersebut menunjukkan bahwa hasil produksi wijen di dalam negeri lebih kecil dibandingkan tingkat konsumsinya (Anindita, 2007). Kendala utama dalam pengembangan wijen adalah rendahnya hasil panen. Salah satu cara untuk meningkatkan produktifitas yaitu dengan cara pemupukan. Tujuan penelitian ini adalah untuk mengetahui pengaruh pemberian pupuk N, P, K dan pupuk kandang sapi serta interaksinya terhadap pertumbuhan dan hasil wijen. Penelitian dilaksanakan pada bulan Februari sampai Juni 2013 di Kebun Percobaan Fakultas Pertanian Universitas Brawijaya, Desa Jatikerto, Kec.Kromengan, Kab. Malang. Penelitian ini merupakan percobaan faktorial yang terdiri dari dua faktor yang disusun berdasarkan Rancangan Acak Kelompok yang terdiri dari 3 ulangan. Adapun perlakuannya sebagai berikut : faktor pertama yaitu pemberian dosis pupuk N, P dan K, faktor kedua yaitu pemberian dosis pupuk kandang sapi. Hasil penelitian menunjukkan bahwa pemberian pupuk kandang sapi 1000 kg ha-1 dan pupuk anorganik 100 kg ha-1 Urea + 50 kg ha-1 SP-36 + 50 kg ha-1 KCl dapat meningkatkan hasil panen, jumlah polong jumlah biji per polong dan jumlah cabang per tanaman. Pemberian pupuk kandang kandang sapi 1500 kg ha-1 dan pupuk anorganik 150 kg ha-1 Urea + 100 kg ha-1 SP-36 +100 kg ha-1 KCl dapat meningkatkan berat kering total tanaman, bobot total biji per polong, bobot kering total gulma

Antimicrobial Activity of N-hexane Extracts of Red Frangipani (Plumeria Rocea)

Antimicrobial assay of n-hexane plant extracts against Escherichia coli and Staphylococcus aureus had been done. Extraction with n-Hexane of the flowers yielded 2,08% of extract, while leaves and stems yielded 3,21% and 2,19% of n-hexane extracts, respectively. The extracts showed different activity against both bioindicators. The leaves extracts showed the strongest activity indicated by wider diameters of inhibition zone, 19,7 mm against E. coli and 13,3 mm against S. aureus at 10% of the extracts' concentration. At the same concentration (10%), the steam and flower extracts showed less inhibitory activities with 11,3 mm and 8,3 mm against E. coli, and 12,0 mm and 11,0 mm against S. aureus. At the lowest concentration of the extracts, the leaves extracts showed the strongest activity against E. coli (14,3 mm) while the steam extracts showed highest inhibitory activity against S. aureus ( 7,7 mm). Based on antimicrobial assay, it was suggested that the leaves extracts demonstrated strongest activity than other extracts. It was assumed that leaves extracts contained more secondary metabolite than flowers and steams, and the leaves have phenol compounds which are not present in other extracts

Germ Plasm Diversity of Groundnut Based on the Character of Morphology, Result, and Oil Content

Groundnut is one of the largest vegetable oil and has a good nutritional value. It could be used as an alternative source of food, industrial raw materials, and bioenergy. The main function of fats and oil in seeds reserves source of energy. This research aims to study the diversity of morphological, yield, and the oil content in groundnut germplasm. The planting of groundnut was conducted at the experimental station Cikeumeuh BB Biogen Bogor from July until December in 2013, with the germplasm of groundnut as much as 200 accessions. The characters identification is determined by the method of morphological characterization with Groundnut Descriptor from IPGRI. Analyze oil content of groundnut used soxhlets method at the Laboratory of Post-harvest Bogor. The results showed that germplasm groundnut have varied levels of diversity at characters. Relatively high morphological diversity founded the character of pod yield/plot, weight of pods/plant and number of immature pods. Groundnut oil content is range 33% to 47%. There are a real positive correlation between the number of pods to variable morphology, yield and oil content, but negatively correlation at weight of 100 seeds. Number of pods and number of branches is positively correlation with oil content of groundnut seeds. Cultivars groundnut that have the characters of promise could be used as national asset and the source of genes as a parent in the breeding program

Perceptual visual dependence for spatial orientation in patients with schizophrenia

BACKGROUND: Patients with schizophrenia are reported to have vestibular dysfunction and to weigh vestibular input to a lesser extent compared to healthy controls. Such deficits may increase visual dependence (VD) for spatial orientation at a perceptual level in these patients. The aim of this study is to compare VD levels between healthy control and patients with schizophrenia and to explore associations between VD and clinical measures in these patients. Relation of VD to antipsychotic drug treatment is also discussed. METHOD: 18 patients with schizophrenia and 19 healthy controls participated in this study. The Rod and Disc Test (RDT) was used to create an optokinetic surround around a centrally located rod. Participants aligned the rod to their subjective visual vertical (SVV) in both static and dynamic disc conditions. VD was calculated as the difference in SVV between these two conditions. RESULTS: There was no group difference or gender difference in static or dynamic SVV as well as VD. There was no correlation between VD and any of the Positive and Negative Syndrome Scale (PANSS) scores, however VD was significantly correlated to illness duration in the patient group. CONCLUSIONS: Schizophrenia is not associated with greater VD levels at a perceptual level, compared to controls, indicating adequate visuo-vestibular integration for judging line verticality in these patients. Patients with greater chronicity of the disease are more visually dependent than those less chronically ill, consistent with previous reports of possible vestibular dysfunction in patients with schizophrenia. This may affect their daily functioning in dynamic visual environments
