Introduction: Weil syndrome, a rare infectious disorder, is a severe form of the bacterial infection caused by Leptospira bacteria known as leptospirosis. Weil syndrome is characterized by dysfunction of the kidneys and liver, abnormal enlargement of the liver (hepatomegaly), persistent yellowing of the skin, mucous membranes, whites of the eyes (jaundice), and/or alterations in consciousness. In most cases, Weil syndrome occurs among individuals who are exposed to affected animals. Case Presentation and Summary: The investigation of death was done by a team consisting of doctor, junior health inspector, and ASHA workers of the area. We did a qualitative approach of in-depth interview of the wife and daughter-in-law of the deceased for data collection. The patient’s name and other details are not revealed for anonymity. No particular statistical analyses are used for this case reporting. The CARE guidelines were followed for writing this report. Conclusion: Leptospirosis is a disease of outbreak potential and has high case fatality rate. Timely identification of cases and institution of preventive measures is very important in preventing outbreaks. The surveys conducted in the area did not reveal any signs of an imminent or ongoing outbreak of leptospirosis.

Land use in Lumajang Regency is dominated by agricultural land. However, over time there was a conversion of agricultural land into residential land as a result of an increase in population. The purpose of this study was to determine the pattern and area of optimal land-use allocation increase economic value in Lumajang Regency. The method used in this study was linear programming with the simplex method. The maximum farming income obtained from optimizing land use is Rp710,306,800,000.00. The optimal land-use area for paddy fields is 42,686.71 ha, the protected forest is 12,652 ha, and residential land is 18,284 ha. The optimal proportion of land use is 58% rice fields, 17% protected forests, and 25% settlements. The optimal paddy field area has decreased by 6,003.26 ha from the land area in 2018 because there are paddy fields that do not match their characteristics. The largest area of rice field reduction in Candipuro District is 2,138.51 ha. Meanwhile, the direction for the allocation of residential land has increased settlement land from 2018 with an area of 1,114.1 ha. The development of residential land is allocated to land that has been planned for settlement in the Spatial Planning (RTRW), potential land that has a slope value of 0 - 25%, and areas with low population density. The largest additional area of residential land in Pronojiwo District is 300 ha.

The high land conversion rate to other sectors has led the government to issue Law No. 41 in 2009 concerning Protection of Sustainable Agricultural Land (SAL). The study aims to identify the distribution of sustainable agricultural land uses and determine agricultural land-use changes from 2016 to 2019 and determine farmers' understanding of sustainable agricultural land control in the strategic area of Garut Regency. We overlaid the land use maps of Garut Regency in 2016 and 2019 and conducted a survey using an online questionnaire with a Google form. The research location is in five districts in Garut Regency. The results showed no land conversion in the area of existing sustainable agricultural land in Garut Regency. The total rice field area is 6,081 hectares, with about 24% is sustainable agricultural land. From 2016 to 2019, the rice field area decreased by 12 hectares. The farmers' awareness of SAL tends to be more likely aware of the sustainable agricultural land area, as many as 39% of farmers aware of sustainable agricultural land. The incentives given to farmers who control sustainable agricultural land are tax deduction, agricultural infrastructure supply, agricultural production facilities subsidies, and land certification facilities. The majority of the respondents are aware of these incentives. In conclusion, no sustainable agricultural land is converted, even though changes occur in non-sustainable agricultural land. The impact of this study is for recommendations to the government in sustainable agricultural land management.

Background and Hypothesis:  Autism spectrum disorder (ASD) is a form of intellectual disability with impairments in social functioning and cognition. Mutations within the SynGAP1 gene are associated with ASD due to over activation of RAS-GTP causing insertion of AMPA receptors onto the post synaptic membrane, and thus early maturation of dendrites. These mutations lead to an excitatory/inhibitory imbalance within the brain, and patients often present with intellectual disability, seizures, and issues of cognition. Research has shown that Syngap1 +/- mice have decreased cortical gray matter brain volume throughout areas involved in the visual system pathway. However, hierarchal visual processing has not been well characterized in a Syngap1 +/- mouse model of autism.   Project Methods:  Using 64 and 128 channel microelectrodes, we recorded the neural activity within V1 of four mice. Neural activity was recorded in response to visual stimuli - testing receptive field size between two wild-type and two Syngap1 +/- mice. Data was run through spike sorting algorithms to identify neurons. Receptive field area for each neuron was then calculated and compared between the two genotypes.   Results:  The receptive field areas of Syngap1 +/- mice were statistically larger (p < 0.01) compared to wild type mice. Syngap1 +/- mice had a mean receptive field area of 450.5 visual degrees (±443.7) and WT mice had a mean receptive field area of 261.1 visual degrees (±187.21). Most of the neurons within Syngap +/- had no distinct receptive field, 67.9%, while only 25.7% of wild type neurons lacked a distinct receptive field.   Conclusion and Potential Impact:  Overall, Syngap1 +/- mice had larger, and less distinct receptive fields compared to wild type mice. Deficiencies in the Syngap1 protein may impair refinement of visual stimuli. Understanding the mechanism of response of missing SynGAP1 can inform directed therapies and interventions to treat patients with the missing gene and manage their intellectual disability.

Abstract A novel double negative curvature nested fiber structure is designed by adding extra circular cladding tubes to enhance the birefringence and reduce the confinement loss. The fiber structure is composed of eight circular cladding tubes and two semi-elliptical nested tubes. The transmission performances of terahertz fiber, including birefringence, confinement loss, dispersion and effective mode field area, are studied by changing the parameters of cladding tubes. In the frequency range of 1.75 - 2.6 THz, the broad bandwidth of 850 GHz with high birefringence (above 10-4) can be achieved. The confinement loss of y-polarization mode with the frequency of 2.575 THz can be as low as 0.00231 dB/cm. The waveguide dispersion coefficient is between ±0.188 ps/(THz•cm) in the frequency range of 2.0 - 2.475 THz. The maximum effective mode field area of x- polarization mode is 2.618×10-6 m2 at 2.6 THz.

Tangkup Village has an area of 2,667 Km2, most of which is in the form of rice fields. The natural tourism potential of Tangkup Village is a rice field area located in Tangkup Anyar, a watershed located in Tangkup Desa area, and green hills that surround the village. Cultural potential in the form of cagcag woven cloth which is a typical product of Tangkup, traditional snacks called jaje tulud, tipat pesor and sangait. In other places, sangait is made from sweet potatoes, Sangait in Tangkup village is made from cassava which is widely grown by local people. However, in the process of developing this snack product, it encountered obstacles related to the dough that did not support the process of design tulud cakes with coconut shells. Even though the community wants to develop jaja tulud, the tools used should not be replaced. Because of these difficulties, not many residents survive to make jaja tulud which is usually used for ceremonial needs. Regarding its function as a typical snack, students want to develop this snack so that it can be of economic value and accepted by tourists through a more elegant presentation. Students are actively involved in the preparation for the formation of Pokdarwis so that the direction of village development is towards a managed and directed tourism village. So far, the potential management of Tangkup Village is still being handled independently by utilizing the land owned, especially those located near watersheds, in the form of cafes, rafting, Asta Gangga Park attractions and bamboo houses that are being built as tourist facilities on the hill. The village hopes that students will help generate the tourism potential of Tangkup Village, so that it is widely known and visitors enjoy the beauty of this beautiful fertile village through the preparation of local human resources to welcome Tangkup village which will soon become a tourist village.

The main purpose of stemming is to reduce the inflected words into its root form or stem. Thus, words can be mapped to the same concept, improving the process of information retrieval, regarding its ability to index documents and to reduce data dimensionality. However, the efficiency of those algorithms varies according to different aspects. Also, studies in the field area reached contrasting conclusions. This work assesses the use of stemmers in the retrieval of legislative documents written in Portuguese. Four stemmers together with BM25 were evaluated in two legislative corpora from the Brazilian Chamber of Deputies. RSLP-S and Savoy stemmers showed the best improvements in the information retrieval pipeline.

The purpose of this research-based service program is to apply the research results of the proposing team's research for community empowerment. The application of the research results was carried out on the program of application of appropriate technology for automatic fish feed and automatic bird repellent on the Minapadi jajar legowo system which is a system of planting rice with fish cultivation in one rice field area simultaneously and the jajar legowo planting system with a spacing of 25 cm . The technology used is automatic feeding and automatic bird repellent. Automatic feeding is done by using a mini water pump that has been modified with the help of a digital timer so that the feed automatically dispenses the feed at the time we specify, which is 3 times a day. The second technology is automatic bird repellent using extracts of herbal ingredients (jengkol) with the help of an automatic sprayer. This technology aims to increase the income of farmers with high productivity of rice yields and increase local fish production. The activity was carried out for 5 months in Beutong Nagan Raya District. The observed results include the feed that comes out of the automatic device as much as 15 gr/second, adjusted for the number and weight of fish. Meanwhile, the air pollution that comes out every 10 minutes is 5 units in a 25m2 plot.

Carrot is one of the vegetables that people like because it has many health benefits related to the content of B vitamins, vitamin C, and other substances, thereby increasing the need or demand, but not in line with the increase in the production of this plant. One of the efforts to increase production is through area expansion, and the lowlands are the target of its development. This study aims to determine the growth and yield of carrots grown in the lowlands by applying rice straw mulch. This research was conducted in a rice field area, in Bagek Polak Village, West Lombok Regency, West Nusa Tenggara with an altitude of 26 m above sea level in July-October 2020. The field experiment with the experimental method was designed according to a Randomized Block Design with one factor, namely the thickness of rice straw mulch. (m0 = no straw mulch; m1 = 1 layer mulch thickness; m2 = 2 layers mulch thickness; m3 = 3 layers mulch thickness; m4 = 4 layers mulch thickness) was repeated four times so that there were 20 experimental units. The results showed that rice straw mulch had a significant effect on the growth and yield of carrots in the lowlands. The use of 4 layers of rice straw mulch was could increase the growth and yield of carrots by 2647.75 gr/m2 or the equivalent of 21,182 tons/ha. layer; expansion; production; vegetables; tubers
