Maize stomata are shown to be markedly affected by severe drought lasting about a week or more, in that they do not recover their apparent pattern of normal behaviour after the water supply to the plant is restored, although the leaves regain their turgidity and seem normal. On the other hand, sorghum stomata recover well from severe drought lasting 14 days and their recovery follows fairly closely behind the restoration of turgidity to the leaves. It is suggested that this difference in ability of stomata to recover from severe drought in some measure accounts for the superiority of sorghum as a grain crop in dry regions.Severe drought in maize is shown to be less damaging to the young plant than to the old, because the stomata of the unopened leaves behave normally when unfolded after the drought is broken.

The formation of agarwood resin can be accelerated by natural or artificial intervention of Aquilaria tree. Many planters developed varies inoculant or inducer in order to accelerate the formation of agarwood. Aquilaria trees require more than 20 years to form natural agarwood formation naturally, thus it becomes impractical especially for commercial purposes. On the other hand, the production of varies booster commonly unequipped with standard inoculating apparatus. The existing agarwood-inducing techniques require longer time to complete the inoculation process for each tree. Therefore, this study aims to develop a novel automated transfusion set for facilitating the inoculation process of Aquilaria tree. An automatic transfusion is equipped with magnetic sensor to monitor the inoculants volume. The automated transfusion set operated by 12V water pump that controlled by Arduino controller to give a constant pressure during inoculation process. The infusion of inoculants also controlled by Arduino controller with aids of magnetic sensor. Hence, the total volume of inoculants being infused inside the Aquilaria tree can be monitored. The result for the automated transfusion is indeed reduces the time of inoculation process which is roughly 70 ml in 2 hours compared to the conventional techniques (whole tree inoculation and syringes inoculation) by 2 hours for 50 ml. Thus, this invention is potentially benefitting the planters to reduce time and laborious particularly in inoculating liquid inducers or inoculants.

Research on the supply system of the Alcazar of the archbishops in Alcalá de HenaresSeven years after the reconquest in 1118, Alkal’a Nahar (Alcalá de Henares) to Muslims, thanks to the Toledo archbishop, Bernardo de Sedirac, King Alfonso VII donates this population, to the archbishopric of Toledo. During the Muslim domination, a fortress with an important suburb had been built on the nearby hills, known as Alcalá la Vieja which, from that moment, was gradually abandoned, to settle on the plain, next to the old Church of San Justo. The archbishops were aware of the historical and religious importance of this site and with their policies, they were reinforcing and attracting more population. Most of the researchers think that it was Ximénez de Rada (1209-1247), who began the construction of the headquarters of the Toledo archbishops in Alcalá de Henares, formed by a fortress and a walled enclosure, probably over what there was it has been an extensive agricultural farm. Associated with this, there are news of the existence of waterwheel, from the Muslim era in this place. On the other hand, there is a reference that places around 1300, the construction of a “viaje de agua” for water supply. Little else was known about the supply system of the Alcazar. Thanks to the research carried out, we have learned that the construction of said infrastructure is based on the ancient Arab technique, known as qanat. These are mines that drain the aquifer, about two kilometers upstream, to the north and transport the water to the walled enclosure. The main advantages of this system of supply, is that the water is captured far from the fortification and can also be tubed and taking advantage of the existing slope, maintaining the pressure, to make the water sprout above ground level, forming sources.

This paper examined the effects of climate change on rural development in Nigeria. In this paper, rural development was measured by the percentage of the population with access to improved water supply. On the other hand, the measures of climate change employed in this paper are precipitations, variations in temperature and per capita carbon dioxide emissions. Data on the variables were sourced from the World Development Indicators (WDI) and the analytical techniques include descriptive statistics, unit root test, Hansen cointegration test and Fully-Modified Least Squares (FMOLS). The Kwiatkowski Phillips Schmidt and Shin (KPSS) unit test results show that the variables are mixed integrated with combinations of I(0) and I(1). It was observed from the Hansen test for cointegration that the test statistic with probability value (0.192) indicates that the variables are cointegrated. This suggests that the null hypothesis of parameter stability cannot be rejected. It was found from the estimated cointegrating regression model that precipitation and temperature are significant in influencing changes in access to improved water supply in rural Nigeria. Whilst precipitations negatively influenced access to rural water supply, changes in temperature enhanced rural water supply. The negative effects of precipitations on rural water supply could be attributed to the flooding usually associated with precipitations which tend to contaminate the various water sources in the rural areas. On the other hand, per capita carbon dioxide emissions do not significantly affect access to improved water supply in rural area. Given the findings, it was recommended for policy makers to adopt proactive and innovative approaches by synergizing with the relevant stakeholders to significantly address the problem of climate change and improve opportunities for rural development.

Telah dilakukan penelitian untuk menentukan konsentrasi fosfat tersedia pada tanah sawah dan membandingkan dua metode ekstraksi fosfat, yaitu metode olsen yang menggunakan reagen NaHCO3 dan metode bray yang menggunakan reagen Bray dan Kurtz. Hasil ekstrak direaksikan dengan pereaksi pewarna fosfat bersama deret standar dan diukur absorbansinya menggunakan spektrofotometer pada panjang gelombang 693 nm. Hasil penelitian menunjukkan bahwa ekstrak fosfat tersedia dari metode Olsen menunjukkan hasil konsentrasi yang tinggi berturut–turut 422,861; 771,614; 1389,464; 1607,386; 821,591; dan 1139,925 ppm, sedangkan metode Bray menunjukkan hasil yang lebih rendah berturut-turut 16,102; 13,899; 11,307; 7,181; 7,183; dan 9,073 ppm. Reagen NaHCO3 pada sampel menyebabkan pH naik sehingga banyak fosfat yang terlepas, sedangkan reagen Bray dan Kurtz menyebabkan pH turun dan lebih sedikit fosfat yang terlepas. pH sampel yang bersifat asam menyebabkan metode Bray lebih cocok untuk digunakan daripada metode Olsen karena metode Bray spesifik untuk tanah asam, sedangkan metode Olsen dapat digunakan untuk tanah asam dan basa.A study aimed to determine the concentration of phosphate available to the rice field soil and to compare the two methods of phosphate extraction, which are Olsen that uses NaHCO3 reagent and Bray that uses Bray and Kurtz reagents, had been done. The extract was reacted with phosphate coloring reagent and standards and the absorbance was measured using spectrophotometer at a wavelength of 693 nm. The results showed that the extract of phosphate available using Olsen method showed higher value of concentrations which were 422.861; 771.614; 1389.464; 1607.386; 821.591; and 1139.925 ppm. On the other hand, Bray method showed a lower value which were 16.102; 13.899; 11.307; 7.181; 7.183; and 9.073 ppm. NaHCO3 increased the pH and more phosphate was released, while the Bray and Kurtz reagent decreased the pH and less phosphate was released. Due to the lower pH of the sample, Bray method is more suitable for acidic soils rather than Olsen method because of its specificity for acidic soil, while the Olsen method can be used for acidic and alkaline soil.

The occurrence of three species belonging to the small coenobia forming green algae Desmodesmus and Didymocystis is reported from the northernmost part of Lake Tanganyika, East Africa. During a monitoring between September 2011 and October 2013 the highest number of cells of Desmodesmus bicellularis and Didymocystis comasii were observed in August and September, at the end of the dry season. On the other hand, the third taxon, Didymocystis cf. inermis, was only sporadically observed between September 2011 and March 2012. According to existing databases, it should be the first records from Africa of these three species. However, D. bicellularis (as Didymocystis bicellularis) was already reported in 2003 in phytoplankton samples of the pelagic zone from more southern located places in Lake Tanganyika.

Up to the present time the compost heap of sugar cane has not yet been untilized to the greatest extent. The compost heap, however, has been a major animal feed. In Indonesia about 6.49 million sugar cane tops, 2.78 million ton kletekan and 1.86 million ton sugar sogolan can be obtained each year. By product of sugar processing can yield bagasse, blotong and molasses. All of these by products are potential as a substitute for common forage in ruminants particularly during a relatively long dry season as long protein sources provided. On the other hand the supply of animal feed is becoming scarce and expensive. The farm land growth is limited, especially in dry season. With regard to the potentials mentioned along with animal feed technology, the compost heap of the sugar cane can be converted into essential animal feed. The waste of sugar cane can be processed become wafer and the use can reached 50 – 55 % from the total of the forage in ruminants.Key words : waste, sugar can, forage, wafer, ruminants.

: Currently, the Lamtoro plant has become the prima donna of forage for ruminants in NTB Province. This plant is able to grow in relatively dry land and can be a source of protein for ruminants, maintenance and maintenance is relatively easy because it does not require a lot of water. On the other hand, the use of lamtoro as a source of protein for ruminant feed is an efficient step in meeting animal feed needs. Through the utilization of lamtoro, the use of less productive land can be utilized as well as a reforestation tree to prevent erosion, on the other hand, the use of lamtoro can increase farmers' income because the cost of foraging for food in the dry season can be minimized, the quality of feed given to livestock is maintained so that livestock productivity is maintained. The dry season remains high, therefore the Maju Bersama Group in the Filter Village of North Moyo District as one of the livestock groups in North Moyo District where the population does a lot of raising ruminant livestock, it is deemed necessary to carry out community empowerment service activities through counseling on “Lamtoro Cultivation As a Protein Source Feed Bank in North Moyo District, Sumbawa Regency. " Providing counseling in the form of demonstrations, speeches (lectures and questions and answers), and distribution of leaflets attended by 20 participants including members of farmer groups and local residents. The results of the counseling were considered very useful. This could be seen from the enthusiasm of the extension participants who attended both the question and answer session and the demonstration session. The output of this counseling result is an ISSN service journal and a brochure

A series of catches of G. pallidipes Aust. was made in 1½-hr. periods between 0800 and 1830 hr. each day during two experiments carried out in the early wet season (1957) and the late dry season (1958), at Lugala, Uganda, using tethered, small, shorthorned East African Zebu oxen, Morris traps and the standard flyround technique.Flies were attracted to the oxen in greater numbers in the morning and evening than at midday, the evening increase being marked in the wet season. The daily catches of both sexes on oxen, though starting at much the same level in both seasons, fell to lower levels at the hotter times of day during the dry season and rose only slightly in the evening. Traps, on the other hand, in both seasons caught most females between 1230 and 1400 hr. and least in the mornings. Male flies were trapped in greatest numbers between 1400 and 1530 hr. in the wet season, but only in comparatively small numbers at any time in the dry season, though there was a suggestion of maximum availability between 1100 and 1230 hr. during the latter. During the dry season, catches on the fly-round and on oxen showed a similar periodicity in the case of females, but not in that of males, fly-round catches of which declined from a peak at 0930–1100 hr.

ABSTRACTThe Effects of Recorded Predator Noise on Metabolism and Daily Activities of Rice-field RatThe use of poisonous rodenticides for controlling rice-field rat (Rattus argentiventer) in agricultural storehouses is the most common option, recently. This option was the easiest, the most effective and also efficient. In the other hand, the application of poisonous rodenticides causes various harmful risks. Rodenticides have potentialities for poisoning human, non-target animals, and other components of environment such as water and soil. The experiment aimed to explore the effects of recorded predator noise on metabolism and daily activities of rice-field rat. Results showed that the recorded of predator noise caused metabolic disorders that were indicated by the decrease of food and beverage intake by rice-field rat and the decrease of its body weight significantly, while the daily activities disorders were indicated by spending more time for locomotion and less time for foraging and resting. In conclusion, the treatments have an effect as repellent for rice-field rat.Keywords: Rice-field rat, Repellent, Pest, Metabolism, Daily activitiesABSTRAKPengendalian tikus sawah (Rattus argentiventer) di gudang-gudang tempat penyimpanan produk pertanian selama ini mengandalkan cara pengendalian kimiawi dengan menggunakan rodentisida. Salah satu potensi berbahaya dari cara pengendalian tersebut adalah sisa-sisa repihan rodentisida dapat pula mengontaminasi produk pertanian secara langsung, juga mengontaminasi lingkungan termasuk tanah dan air. Penelitian ini bertujuan untuk mengekplorasi pengaruh rekaman suara predator tikus yang diputar secara terus menerus dan berulang-ulang terhadap metabolime dan aktivitas harian tikus sawah di laboratioum yang selanjutnya dapat dimanfaatkan untuk pengedalian tikus sawah yang aman dan ramah lingkungan. Hasil penelitan menunjukkan bahwa tikus sawah yang diberi perlakuan suara predator mengalami gangguan metabolime yang ditandai dengan konsumsi makan dan minum, serta produksi feses dan sekresi urin yang berbeda dengan kontrol di kandang metabolisme. Tikus sawah yang diberi perlakuan suara predator juga mengalami gangguan pola aktivitas harian yang ditandai dengan jumlah waktu yang dihabiskan untuk locomotion (bergerak), foraging (makan dan minum) dan resting (terdiam dan tidur) yang berbeda dengan kontrol. Hasil ini menunjukkan bahwa suara predator memiliki potensi untuk diaplikasikan pada lokasi-lokasi tertentu, terutama gudang penyimpanan produk pertanian dengan tujuan untuk menolak dan mengusir serangan tikus sawah.Kata Kunci: Tikus sawah, Repelen, Hama, Metabolisme, Aktivitas harian
