Recovery of Valencia Groundnut (Arachis hypogaea L.) Traits in Early Segregating and Promising Late Leaf Spot Resistant Populations
Authors: Wambi Wilder
Published: March 2021

In Uganda, there are no Valencia varieties that are resistant to leaf spot diseases. Introgression of resistance genes into elite lines is always associated with the transfer of undesirable traits from the donor parents. Knowledge of the degree of genetic relationship provides breeders with a more efficient way to identify populations of potential relevance for their plant improvement programs. The objective of this study was to determine the recovery of Valencia groundnut traits in the early segregating and promising late leaf spot (LLS) resistant populations. Four crosses between Valencia lines (P1) and donor lines (P2) were made. The populations that included F1, F2, BC1P1 and BC1P2, together with their parents (P1and P2) of each of the four crosses namely, Valencia C (P1) × ICGV-SM 02501 (P2), Valencia C (P1) × SGV-07009 (P2), NuMex-M3 (P1) × ICGV-SM 02501 (P2) and Redbeauty (P1) × ICGV-SM 03590 (P2) were evaluated. Cluster analysis revealed differences among the generations for the traits analysed with major and sub-clusters, implying that the generations of crosses formed a genetically diverse population that offers possible opportunity for selection. In the cross between NuMex-M3 X ICGV-SM 02501, the populations BC1P1 and F2, exhibited higher (80 %) recovery of the recurrent parental (NuMex-M3) traits. Similarly, the backcross population (BC1P1) to the susceptible elite variety of the Valencia C X ICGV-SM 02501 cross recovered approximately 75% of the recurrent parental traits Valencia C with lower LLS disease score. Such populations could result in higher gain in Valencia traits and LLS resistance when utilized the breeding program. For maximum gain in LLS resistance and recovery of Valencia traits, more selfing and backcrossing can be performed to fix the genes for LLS resistance as well those of Valencia characteristics. Keywords: cluster analysis; Arachis hypogaea; diverse populations

Riverine ecosystems are continuously been compromised by human activities resulting in threatening their integrity. In this study, integrity of Upper Victoria Nile River was assessed using habitat quality and fish biotic indices. Experimental gillnetting was done bi-annually in 9 stations along the river from 2008 to 2018. Nine habitat metrics were used to estimate habitat quality index at every sampling station. Fish sampled, were sorted, identified to species level, and weighed. Counts of introduced and indigenous as well as tolerant and intolerant species were recorded to generate species richness. A total of 10.642 fish, 65 species belonging to nine families were recorded. Dominant species were Lates niloticus 62.79%, Oreochromis niloticus 23.51%, Mormyrus kannume 13.64%; other species were ≤0.06%. Tolerance and trophic guild showed carnivores (61.5%), omnivores (21.5%) and detrivores (16.9%).Mean habitat quality index, total fish catch and fish-based index of biotic integrity varied among stations with highest record of 26.6±6.9, 289.2±51.8 and 30.6±7.9 at sampling station (ST4) respectively. The lowest was 19.4±7.3, 93.1±13.2 and 26.7±6.8 at sampling station (ST2) respectively. On a spatial basis, indices recorded significant differences among stations (p < 0.05). Results indicated a fair fisheries biodiversity that need better conservation management of habitat type of the upper Nile.

This study was conducted to isolate and characterize Edwardsiella tarda (E. tarda) and assess its antimicrobial susceptibility. The bacterium was isolated in Wakiso District, Uganda, from symptomatic and asymptomatic Nile tilapia and African catfish raised in earthen ponds, tanks and cages between September 2016 and February 2017. The bacterium was then identified using conventional biochemical tests and API 20E test kits and characterized by sequencing 16S rRNA gene. The antibiotic susceptibility of 16 drugs was established using the Kirby BeurDisc diffusion method. Eight E. tarda isolates were identified using conventional biochemical tests but only one isolate was confirmed to be E. tarda by PCR. Phylogenetic analysis indicated a distant relationship with other 16S rRNA gene sequences retrieved from the GenBank. Six virulence genes (CitC, muk, gadB, katB, esaV, and fimA) that enhance bacterial survival and pathogenesis in the host were detected. The isolate registered low levels of antibiotic resistance as it was resistant only to Oxacillin, Vancomycin and Penicillin, to which it is intrinsically resistant. This implies low antibiotic usage in aquaculture in the area. Despite its low occurrence, presence of virulent genes in E. tarda indicates its potential to affect fish and human health.

We analyze the economic evolution of a Spanish province that has become a leading region in mass tourism: The Balearic Islands. Environmental data are provided, which complement conventional macroeconomic variables. We analyze the relationship between economic activity and the consumption of natural resources in the Balearic Islands during the period 2000-2017. We find two clear patterns, one before the Global Crisis, and another one after it. We state that the Balearic economic model has become more sustainable since 2008. It implies that public policies, together with own households’ and enterprises’ initiatives in terms of changing production and consumption patterns have paid off and should be continued and deepened.

Published: March 2021

High concentration of contaminants in drinking water can affect human health. This study assessed quality of groundwater at industrial and residential areas of Sango Ota, Ogun State. Water samples were collected in triplicates from 8 wells at industrial and residential areas and analyzed for its physicochemical properties. The pH, electrical conductivity, total dissolved solid (TDS), nitrate, sulphate, total suspended solid (TSS), total hardness (TH), iron, zinc, copper, lead, nickel, chromium and cadmium concentrations in the water samples were determined following American Public Health Association (APHA) procedure. Results showed that pH of 50 % of the wells were lower than minimum limit of 6.5 recommended by WHO. Sulphate, TH and iron in the water were significantly (p < 0.05) higher at residential area than industrial area. Electrical conductivity exhibited significant (p < 0.01) correlation with TDS (r = 0.701**) and NO32- (r = 0.922**) at residential area. At the industrial area however, concentration of salts in water samples was highly associated with SO42- (r = 0.864**) and Cd (r = 0.587**). Across locations of groundwater, iron and lead were above allowable WHO limits in drinking water. Cadmium was also above drinking limit at location T4 of the residential area. Consumers of groundwater in the study area are prone to health related challenges of heavy metal toxicity.

Published: March 2021

Some heavy metals, consisting of Fe, Cd, Co, Cu, Mn, Ni, Pb and Zn were determined using USEPA Method 3050B for total metal concentration. Six composite samples were located from Aladja (ALJ), Ovwian (OVW), Ejevwu (EJW), Ekete Inland (EKI}, Orhuwhorun (ORH), and Otor-Udu (OTU) towns. In addition, chemical speciation was carried out on these samples using method employed by Tessier et al. as modified by Kersten and Forstner to assess their speciation pattern and the fraction of abundance as determinant of environmental pollution. From the results obtained, concentrations of Fe, Cd and Mn were more predominant in the residual fraction (F5) in the form of Fe3+, Cd2+ Mn2+ respectively for both wet and dry seasons. Co was more in the exchangeable fraction (F1) as Co2+ for both seasons. Concentration of Cu in the form of Cu2+ is higher in Fe-Mn oxide fraction (F3) for wet season and dry season’s organic fraction (F4). Pb and Zn were abundant in Fe-Mn oxide fraction (F3) for both seasons as divalent ions. Mobility factor calculated for the metals shows pattern in the order: Pb > Co > Zn > Mn > Fe > Cd > Cu > Ni for wet season and Co > Zn > Mn > Cu > Pb > Ni > Cd > Fe for dry season; which is as a result of changes in some physiochemical parameters such as acidity, pH, among others. From this result, there is the need to ensure that future health catastrophe is averted from the accumulation and release of Pb2+, Zn2+, Co2+ and Mn2+ especially into the environment.
Gas Chromatography- Mass Spectrometry Analysis of Phthalide Composition of Celery oil from Apium graveolens L. cultivated in Nigeria.

Published: March 2021

Phthalides are important bioactive constituents of celery plants. The medicinal uses of celery and their characteristic aroma have been linked to the phthalides. In this report, the leaf and stalk oils of celery were extracted either by hydrodistillation or maceration in water and the phthalide constituents of the oils were characterized by gas chromatography-mass spectrometry (GC-MS) analysis. The leaf oil consists mainly of dihydroxyphthalides while the volatile phthalides are the main phthalides in the stalk oil. The phthalide content of the leaf oil and the stalk oil are 39.8% and 29.95% respectively. The phthalides identified in the leaf oil are the isomeric compounds of senkyunolide I and senkyunolides (J & N), while the major phthalide constituents of the stalk oil include 3-n- butylphthalide, sedanolide, neocnidilide and sedanenolide/senkyunolide A. The results suggest that the Nigerian celery plant could be considered a good source of phthalides which are known for their nutraceutical properties such as anti-oxidant, antitumor, anti- platelet aggregation, hypotensive, hypoglycemic and hypolipidemic properties. Further phytochemical and pharmacological evaluation of the locally cultivated celery are required in order to exploit the medicinal potentials of the plant for applications in pharmaceutical and cosmetic industries.
U-Pb ZIRCON DATING OF MIDDLE EOCENE CLASTIC ROCKS FROM THE GERCUS MOLASSE, NE IRAQ: NEW CONSTRAINTS ON THEIR PROVENANCE, AND TECTONIC EVOLUTION
Authors: Aziz Nabaz
Published: March 2021

The provenance of Middle Eocene clastic rock from the Gercus Molasse, NE Iraq was determined by detrital zircon (DZ) U-Pb geochronology. The Gercus Molasse in the Iraqi segment of the north-eastern Zagros Thrust Zone provides an ideal example of foreland system evolution with respect to the transition from passive margin to the accretionary complex terrene-flexural foreland basins. The DZ U-Pb age spectra from the Gercus Molasse suggest that the foreland sediments either influx from multiple provenances or are the result of recycling from the accretionary complex terrane. During pre-accretion, however, the radiolarite basin (Qulqula Radiolarite, 221 Ma) located along Arabian passive margin likely acted as an intermediate sediment repository for most or all of the DZ. Representative DZ U-Pb measurements revealed that the Gercus clastic rocks fall into several separable age population ranges of 92-102 (Albian-Cenomanian), 221 (Upper Triassic), 395-511 (Cambrian), 570- 645 (Neoproterozoic), 1111 (Mesoproterozoic), and lesser numbers of Paleoproterozoic (1622-1991 Ma) ages. The source of Proterozoic detrital Zircons is enigmatic; the age peaks at 1.1, 1.5, 1.6, and 1.9 Ga (Proterozoic) does not correspond to any known outcrops of Precambrian rocks in Iraq, and it may be useful to continue to search for such basement. The detrital zircons with age populations at 0.63–0.86 Ga probably originated from the Arabian-Nubian Shield. The age peak at 0.55 Ga correlates with Cadomian Magmatism reported from north Gondwana. The age peaks at ~0.4 Ga is interpreted to represent Gondwana rifting and the opening of Paleotethys. The youngest ages populations at 93 Ma indicate that fraction of DZ were transported directly from the contemporaneously active magmatic arc (Zagros Ophiolite segments). The paleogeography and tectonic evolution of the Neogene Zagros foreland basin were reconstructed and divided into two tectonic stages. The early stage is defined by the Campanian accreted terranes (i.e. orogenic wedge) form loads sufficient to produce flexural basin with a deepest part is situated next to the tip of the loads. This flexural basin is filled by the flysch clastics of the Maastrichtian– Early Eocene (i.e. referred to by the Tanjero-Kolosh flysch sequence). The late stage is marked by a synchronized modification of the clastics fill of the basin and changes in dip directions to compensate for the reduction of the load by both erosion and extension and the basin, therefore, was sealed by a shallowing upwards depositional sequence ending with the terrestrial Gercus Formation.
Mineralogy and Chemical Composition of Basalt Stone Tools in Some Iraqi Archaeological Sites
Authors: Al-Zubaidy Aqeel
Published: March 2021

Basalt stone tools were collected from some Iraqi Archaeological Sites. Twenty-one samples were studied petrographically, mineralogically, and chemical composition. Five samples were from the Gaara Depression north of Rutba town, seven samples from Tarmiya, north Baghdad, seven samples from Dalmij site, east of Diwaniya city, and two samples from Jordan, which were used for comparison. The studied samples were classified into three groups, according to their mineralogy and texture: Group A: Vesicular Basalt, Group B: Dolerite, and Group C: Olivine Basalt. These stones most probably were used as a hand axe, grinder, hammer, and other uses, as well as for buildings, like those used in Qasar Al- Azraq and Umm Al- Jamal archaeological sites in Jordan. These basalt rocks most probably were transported by an ancient man from Harrat Al-Sham, which extends through Syria-Jordan-Saudi Arabia, or from NE Syria through a trade route that connected between source areas and the studied archaeological sites in Iraq.

Authors: Alkubaisi Basim
Published: March 2021

Thermal maturity and petroleum generation capacity of the source rocks of Lower Cretaceous Sulaiy Formation were studied and evaluated via modeling the thermal maturation of ten wells in this study by using the Arrhenius equation for chemical reactions or (time-temperature index of thermal maturation). A thermal maturation map of the Sulaiy Formation shows that it a high maturity level increasing eastward; also, the geochemical analysis indicated suitable organic content in quantity and quality to generate hydrocarbons. The onset of oil migration from the Sulaiy Formation is calculated by this study to be at the end of Lower Eocene time (53 million years ago), and as it is a late hydrocarbon generation and migration; thus indicating mainly vertical migration paths. According to quantitative estimation, the oil generated and migrated vertically from the Sulaiy Formation towards the Lower Cretaceous reservoirs in southern Iraq estimated at 42.6 x 109 bbl. This study elevated the status of the Sulaiy Formation to a major source of oil tapped in the Lower Cetaceous reservoirs of southern Iraq.

Published: March 2021

This article is devoted to the unusual history of the creation of the National Museum of Damascus. Nowadays this is the largest repository of literary texts and artifacts of the ancient civilization of Western Asia and the Eastern Mediterranean, so as the Art culture values of the Middle East from the Byzantine time and Arab Middle Ages to periods of Modern age and 20th – 21st centuries. The idea of founding in Syria the National Art & Culture History Museum has started up in the process of organizing the Arab Academy of Sciences in Damascus (1918); it was partly inspired by the reports of the 17th – early 20th centuries travelers on ruins and artifacts which met and found on their ways. The Museum was founded at 1919 and located, and all the Academy, in the medieval madrasah. As a result of the operose archaeological excavations of ancient and medieval sites all over the country, found by chance or pointed towards by written sources, started in the 1920s – 1930s, a small collection has grown into a huge foundation of exhibits from different epochs. During 1936-1950, 1963, 1974 and 2004 for Museum a special building had been built: with halls for expositions and exhibitions, premises for storing funds, a library, a lecture hall and a park.

Статья посвящена необычной истории создания Национального музея Дамаска, ныне — крупнейшего в Сирии хранилища памятников древнейших цивилизаций Передней Азии и Восточного Средиземноморья и художественных культур Ближнего Востока периодов византийского и арабского Средневековья, Нового времени и XX–XXI веков. Идея основания сирийского художественно-исторического музея возникла в процессе организации в Дамаске Арабской академии наук (1918 г.) и отчасти была подготовлена сообщениями путешественников XVII – начала XX века о встреченных на их пути руинах и найденных артефактах. Музей был размещен в 1919 году вместе с академией в средневековом медресе. В результате начатых в 1920–1930-х годах археологических раскопок древних и средневековых объектов, найденных случайно или подсказанных письменными источниками, маленькая коллекция выросла в огромное собрание экспонатов. В 1936–1950, 1963, 1974 и 2004 годах было построено специальное здание с парком, залами для постоянной экспозиции и временных выставок, помещениями для хранения фондов, библиотекой, лекторием.

The experiments were carried out to determine the vacuum-plasma characteristics (mainly erosion and outgassing rate in a vacuum) of the stainless steel 12X18H10T before and after processing the walls of the vacuum chamber with the glow discharge and combined, glow-microwave plasma discharges in argon atmosphere. The current-voltage characteristics, the electron density and electron temperature were measured. It was observed that the discharge voltage in the combined regime is significantly lower than in glow discharges. In some modes, this voltage decrease can be up to 200 V. It was shown that erosion of stainless steel 12X18H10T in the combined discharges is 70 %, less than in the glow discharges. Measurements were made of the outgassing rate of 12X18H10T stainless steel with the thermal desorption probe in situ in the DSM-1 vacuum chamber. It was shown that cleaning the chamber wall by the glow discharge during 5 h leads to a decrease in the outgassing rate from 5.5·10-5 to 1·10-5 (Torr.l)/(s.cm2) . When the chamber wall is treated with GM discharge starting from nearly the same initial conditions the outgassing rate decreased to 3·10-6 (Torr.l)/(s.cm2). Spectral measurements of the plasma radiation of a glow and combined discharges show a decrease in the ratio of the peaks of argon ions and neutrals during the transition from a glow discharge to a combined one.

SIMULATION OF GAS DYNAMICS IN PLASMA REACTOR FOR CARBON DIOXIDE CONVERSION
Authors: Platonov P.P. , Dudin S.V. , Lisovskiy V.A.
Published: March 2021

Numerical simulation of a bulk-type plasma reactor for carbon dioxide conversion with distributed gas injection and pumping has been performed in hydrodynamic approximation by solution of Navier-Stokes equation using the mathematical package COMSOL. It is shown that the geometry of gas injection and pumping, which determines the trajectories of the particles and their residence time in reactor, can significantly affect the energy efficiency of the conversion. Different particles on their way from inlet to pumping hole move along different trajectories and spend different times inside the reactor. If the residence time of the gas in the reactor is less than optimal, the gas conversion will be incomplete. If this time is more than optimal, then an excessive amount of energy will be applied to the already converted gas. It is shown that the reactor height affects significantly the energy efficiency of plasma conversion of carbon dioxide.

Published: March 2021

Di tengah pandemi Covid-19 dalam tahun 2020, kinerja pembangunan sektor energi bervariasi. Konsumsi energi, baik BBM, maupun listrik menurun terutama karena pembatasan kegiatan transportasi dan produksi industri (termasuk UMKM). Produksi energi primer seperti minyak bumi, gas bumi, dan batubara juga menurun atau di bawah target karena terganggunya sistem logistik dan rantai pasok. Investasi di sektor energi menurun, subsidi energi meningkat. Walaupun produksi dan konsumsi energi menurun, namun sumbangan energi kepada pendapatan negara tahun 2020 lebih besar daripada yang ditargetkan. Tahun 2020 menunjukkan perkembangan menggembirakan dalam peningkatan rasio elektrifikasi, sebaran program “BBM Satu Harga”, dan peningkatan jumlah rumah tangga yang tersambung aliran gas bumi. Pemanfaatan energi terbarukan dalam pembangkitan listrik dan bio-diesel meningkat, namun pangsa energi terbarukan dalam bauran energi nasional masih rendah untuk dapat mencapai target 23 persen pada tahun 2025.
The Different Existing Patterns of Landholding System that Determine the Mode of Agrarian Change: A Case Study of Tangkhul Nagas
Authors: S. Machutmi W.
Published: March 2021

Abstract:
This paper focuses on the way tribal communities conceptualised the importance of land, and the different type of landholding pattern system that has affected this agricultural community. There are various intricacies involved in defining the ownership of land: It includes who should own the land and to whom the land should be given out in the form of leasing out for a cultivation purpose? For example, the so called “clan land” should be confined to the clan not outside. This paper, therefore, is an attempt to look at various customs and rituals which have an influence upon the various kinds of landholding ownership system and to make a specific case study of Tangkhul Nagas, situated in the Ukhrul district of Manipur, Northeast India.

Analyzing the Effect of Vaping Use in Teens: A Literature Review and Proposed Solutions
Authors: Ajayi Damilola , Fuchs Bruce , Reiss Dana
Published: March 2021

Teenage vaping is a major public health issue that is emerging globally. This review article examines what influences teens to use electronic cigarettes (e-cigarettes) and vapes, including families, communities, social media, and brand marketing. Nicotine, a common component of e-cigarettes and vapes, is addictive, and teens who are using these products are starting to report negative health outcomes. After a review of the current literature, three recommendations/solutions are proposed to combat this public health issue. As teen e-cigarette use is on the rise, it is clear that the FDA and the federal government need to enforce tougher regulations on e-cigarette and vaping brands, teens need to be properly educated about these products that are on the market, and advertisements for these products need to be regulated.

Published: March 2021

Line cooks in commercial restaurants work intense, high-stress shifts during near sources of heat, rendering them vulnerable to heat stress and occupational injury. However, there is a dearth of literature on heat stress among this population. This study investigated three common commercial kitchen configurations—zone, island, and assembly—to determine which design experiences the highest temperatures and if temperatures were in excess of recommended levels. A total of 11 restaurants were sampled for temperature using a Wet Bulb Globe Thermometer (WBGT). Descriptive statistics indicated that, on average, zone configurations are hotter than other kitchens and could pose a risk of heat stress; however, a Kruskal-Wallis test of significance revealed that this distinction was not statistically significant. Two measurements for zone kitchens were borderline significant, suggesting that future studies with greater statistical power would find significant differences between the kitchen types and further illuminate the risk of heat stress.
A Statistical Analysis of Drug Seizures and Opioid Overdose Deaths in Ohio from 2014 to 2018
Authors: White David , Tran Lam , Ma Lin
Published: March 2021

Objective. To examine the association between drug seizures and drug overdose deaths in Ohio from 2014 to 2018.

Methods. We use linear regression, ARIMA models, and categorical data analysis to quantify the effect of drug seizure composition and weight on drug overdose deaths, to quantify the lag between drug seizures and overdose deaths, and to compare the weight distributions of drug seizures conducted by different types of law enforcement (national, local, and drug task forces).

Results. Drug seizure composition and weight have strong predictive value for drug overdose deaths (F = 27.14, p < 1e-15, R² = .7799). A time series analysis demonstrates no statistically significant lag between drug seizures and overdose deaths or weight. Histograms and Kolmogorov-Smirnov tests demonstrate stark differences between seizure weight distributions of different types of law enforcement (p < 1e-7 for each pairwise comparison).

Conclusions. Consideration of drug composition and weight can inform law enforcement seizure activity. To save lives, law enforcement should emphasize seizures of low weight drugs that contain fentanyl.
An Examination of the Use of a Vocabulary Instruction Strategy (Content Acquisition Podcast) on the Vocabulary Comprehension of Students, Through the Use of Action Research Methods

Academic vocabulary is a strong indicator of a student’s ability to learn subject content. Subject mastery is a strong predictor of academic achievement. Academic vocabulary comprehension is a critical component of academic success that is required for making meaning of new information, and demonstrating mastery of academic concepts through the construction of meaningful, articulate assessment responses.  Repeated exposures to academic vocabulary and multiple opportunities to practice using academic vocabulary are likely integral to the ability to use academic texts in a meaningful way (Townsend, Filipinni, Collins, & Biancarosa, 2012).  This paper reports of an examination of the effect of the use of CAPs (Content Acquisition Podcasts) on vocabulary acquisition among two groups of students, both inclusive, both including ELL students, by two student researchers.

OTRA VEZ LOS CONSORCIOS ADMINISTRATIVOS: NOVEDADES INTRODUCIDAS POR LA LEY 40/2015 DE RÉGIMEN JURÍDICO DEL SECTOR PÚBLICO
Authors: TOSCANO GIL FRANCISCO
Published: March 2021

La Ley 40/2015, de 1 de octubre, de régimen jurídico del sector público es la tercera reforma del régimen legal de los consorcios administrativos en un plazo de apenas dos años, volviendo a alterar nuevamente el status quo de estas entidades. Aunque esta última reforma es en gran medida una refundición de las dos reformas anteriores, también introduce algunas novedades significativas, así como algunas correcciones técnicas, que constituyen el objeto de este trabajo. Entre las novedades introducidas por la legislación estatal básica deben destacarse dos: la introducción de una excepción a la regla de que el personal del consorcio proceda exclusivamente de las Administraciones participantes, y la supresión de la exigencia de que las entidades privadas a las que se permite integrarse en el consorcio lo sean sin ánimo de lucro.

Sektore publikoaren araubide juridikoari buruzko urriaren 1eko 40/2015 Legea administrazio-partzuergoen lege-araubidearen hirugarren erreforma da urte pare bateko epearen barruan, eta berriro aldatu du erakunde horien status quo delakoa. Azken erreforma hau, neurri handi batean, aurreko bi erreformen bategitea den arren, berritasun nabarmen batzuk ere ekarri ditu eta, horiekin batera, zenbait zuzenketa tekniko ere bai, guztiak ere lan honetan aztertu nahi izan direnak. Estatuko oinarrizko legerian sartu diren berritasunen artean bi behintzat azpimarratzekoak dira: bata da salbuespen bat sartu zaiola partzuergoko langileak berorretan parte hartzen duten Administrazioetatik datozenak soilik izan daitezkeela zioen arauari, eta bestea, partzuergoan sartzea ahalbidetzen zaien erakunde pribatuei jada ez zaiela eskatzen irabazi asmorik gabekoak izatea.

Act 40/2015 of October 1st on the legal regime of the public sector is the third reform to the legal regime of administrative consortiums in no longer than two years, where the status quo of those entities has been changed again. Although this last reform is to a great extent a recast of the two previous reforms, it also introduces substantial novelties, together with some technical amendments and that is this works¿ purpose. Outstanding among the novelties introduced by the basic State legislation are two: the introduction of an excepction to the rule that the consortium¿s staff belongs only to the participating administrations and the abolition of the requirement that private entities part of a consortium shall be non-profit bodies.

Published: March 2021

Posyandu (Pos Layanan Terpadu) Kasih Bunda II merupakan pelayanan masyarakat yang bergerak pada bidang kesehatan balita. Posyandu ini memberikan pelayanan kesehatan seperti pengukuran berat badan, tinggi badan, pemberian vitamin A, pemberian obat cacing dan pemberian imunisasi dasar untuk balita. Pencatatan posyandu menggunakan media penulisan, sehingga membutuhkan 1 hari untuk menyelesaikan pencatatan posyandu dan merekap ulang data. Beberapa informasi tentang posyandu tidak tersalurkan seperti sulitnya mendeteksi perkembangan balita karena tidak ada laporan yang mendukung (harus memilah satu persatu data balita). Salah satunya dalam pengisian Kartu Menuju Sehat (KMS) balita, pengisian dapat dibuat lebih efektif dan efisien dengan dibuat secara digital, pengisian KMS tidak perlu melewati tahap yang panjang karena pencatatan, perhitungan, pelaporan terlalu rumit dengan buku-buku laporan yang banyak. Berdasarkan masalah tersebut maka dilakukan pembangunan sistem informasi menggunakan metode waterfall sistem dibangun menggunakan bahasa pemrograman PHP dan Database MySQL. Sistem informasi ini dirancang dengan sistem UML (Unified Modeling Language) yang terdiri dari Usecase Diagram, Activity Diagram, Sequence Diagram dan Class Diagram serta menggunakan Entity Relationship Diagram. Hasil yang diperoleh adalah sebuah sistem informasi berbasis web yang mampu mengelola data posyandu dan membantu pelaksanaan posyandu serta menyimpan arsip-arsip posyandu. Mendapatkan laporan semua balita, data kunjungan balita dan laporan grafik status gizi balita untuk orang tua.

Published: March 2021

Pada Perguruan Tinggi, skripsi menjadi persyaratan kelulusan yang harus diselesaikan oleh setiap mahasiswa melalui proses pembimbingan dengan dosen pembimbing, namun semenjak akhir Maret 2020 mahasiswa tidak dapat lagi bertemu dengan dosen pembimbing secara langsung karena semua aktivitas kampus dilakukan secara daring sebagai bagian dari pencegahan penyebarluasan virus Covid-19. Aplikasi bimbingan daring skripsi mahasiswa ini dikembangkan sebagai media interaksi antara mahasiswa dan dosen pembimbing dengan menyediakan fasilitas untuk unduh berkas, catatan perbaikan digital dan informasi capaian penyelesaian mahasiswa. Agile Scrum digunakan sebagai metode pengembangan yang menghasilkan 4 sprint dengan durasi 336 jam atau sama dengan 9 minggu dimana dalam 1 minggu 8 jam perhari selama 5 hari kerja. Tahapannya dimulai dari penentuan product backlog berdasarkan user stories, sprint, scrum meeting dan demo untuk mendapatkan feedback yang cepat di hadapan klien. Aplikasi ini sebagai solusi sehingga pelaksanaan prose pembimbingan tetap dapat dilakukan secara optimal.
