Desain dan Implementasi Mekanisme Smart Forklift pada AGV Berbasis Raspberry Pi 4 Model B
Authors: Siva Phoa Marcellino
Published: February 2022

Automatic Guided Vehicle (AGV) pallet truck merupakan salah satu jenis AGV yang banyak digunakan di industri. AGV jenis ini merupakan kombinasi AGV dengan mekanisme forklift. Mekanisme forklift digunakan untuk mengangkat dan membawa barang dari satu titik ke titik yang lainnya. Seiring dengan berkembangnya teknologi yang disertai dengan revolusi industri 4.0 maka kegiatan tersebut dapat dilakukan secara otomatis dengan menggunakan robot seperti AGV pallet truck. Pada dasarnya, mekanisme kerja dari AGV pallet truck sama seperti forklift pada umumnya, hanya saja AGV pallet truck sudah beroperasi secara otomatis. Motor DC (Direct Current) banyak digunakan sebagai motor penggerak untuk proses naik turun dalam mekanisme forklift pada AGV pallet truck. Motor DC dipilih karena memiliki torka yang besar untuk pengangkatan beban. Namun, motor DC juga memiliki beberapa kelemahan seperti biaya perawatannya yang mahal dan tingkat kepresisiannya masih kurang akurat. Pada penelitian ini diusulkan mekanisme smart forklift untuk AGV pallet truck yang menggunakan motor stepper dengan tingkat kepresisian tinggi dan torka yang dimiliki juga tidak kalah dengan motor DC. Mekanisme smart forklift diperlengkapi sensor jarak untuk mengukur ketinggian forklift dan jarak antara AGV dengan palet serta raspberry pi 4 model B sebagai controller.

Published: February 2022

Tanaman Tin dengan nama latin Ficus Caric adalah sejenis tanaman buah dari sejenis pohon yang banyak tumbuh di kawasan daerah tropis dan subtropis. Tanaman Tin saat ini sudah banyak dibudidayakan di Indonesia. Buah Tin memiliki buah yang berwarna kuning kecoklatan, dengan rasa yang manis. Cerotelium Fici adalah jenis penyakit karat daun yang menyerang pada daun tin, dan menjadi ancaman terbesar terhadap produksi buah tin. Penyakit lain yang menyerang pada tanaman tin adalah kutu kebul dan virus mosaik. Virus mosaik ini pertama kali muncul di California dan menyebar ke sebagaian besar wilayah Indonesia dan Amerika Serikat. Daun tin yang terinfeksi virus ini menjadi bintik-bintik cokelat menyebabkan pertumbuhan tanaman tin menjadi lambat dan cacat pada buah tin. Dalam perkembangan ilmu pengetahuan dan teknologi, cara untuk mendeteksi penyakit pada tanaman tin seperti karat daun, virus mosaik dan kutu kebul dapat dilakukan dengan bantuan pengolahan citra. Untuk itu penelitian ini bertujuan melakukan pengolahan citra berupa segmentasi K-Means pada citra daun tin yang dianalisa dengan ekstrasi fitur GLCM dan mengklasifikasikan Naïve Bayes untuk mendapatkan akurasi terbaik dalam klasifikasi penyakit citra daun tin. Setelah itu, dilakukan analisis tekstur menggunakan metode Grey Level Co-Occurance Matrix (GLCM) dan segmentasi K-Means clustring dalam pengolahan citra daun tin.

Free and Open Source Software for Computational Chemistry Education
Authors: Lehtola Susi , Karttunen Antti
Published: February 2022

Long in the making, computational chemistry for the masses [J. Chem. Educ. 1996, 73, 104] is finally here. Our brief review on free and open source software (FOSS) packages points out the existence of software offering a wide range of functionality, all the way from approximate semiempirical calculations with tight-binding density functional theory to sophisticated ab initio wave function methods such as coupled-cluster theory, covering both molecular and solid-state systems. Combined with the remarkable increase in the computing power of personal devices, which now rivals that of the fastest supercomputers in the world in the 1990s, we demonstrate that a decentralized model for teaching computational chemistry is now possible thanks to FOSS packages, enabling students to perform reasonable modeling on their own computing devices in the bring your own device (BYOD) scheme. FOSS software can be made trivially simple to install and keep up to date, eliminating the need for departmental support, and also enables comprehensive teaching strategies, as various algorithms' actual implementations can be used in teaching. We exemplify what kinds of calculations are feasible with four FOSS electronic structure programs, assuming only extremely modest computational resources, to illustrate how FOSS packages enable decentralized approaches to computational chemistry education within the BYOD scheme. FOSS also has further benefits driving its adoption: the open access to the source code of FOSS packages democratizes the science of computational chemistry, and FOSS packages can be used without limitation also beyond education, in academic and industrial applications, for example.
Synthesis of 4-Imidazolidinones from Diamides and Ethynyl Benzio- doxolones vis Double Michael Addition: Ethynyl Benziodoxolones as Electrophilic Ynol Synthons

Published: February 2022

The moiety of 4-imidazolidinone is an important structural motif in organic synthesis and medicinal chemistry. We achieved the efficient synthesis of 4-imidazolidinones from a variety of diamides by double Michael addition, a novel reaction mode for hypervalent alkynyl iodine compounds, and a formal reductive elimination sequence using in situ-generated EBX from TMS-EBX or EBX-MeCN. The highly reactive EBX enabled chemoselective intermolecular N- alkenylation of the sulfonamide moiety and intramolecular cyclization of the amide moiety under mild basic conditions. The reaction diastereoselectively gave cis-2,5-disubstituted 4-imidazolidinones from amino acid-derived diamides. Furthermore, 2-[(2-iodobenzoyloxy)methyl]-4-imidazolidinone was derivatized by solvolysis and Sonogashira coupling. DFT calculations indicated that the double Michael addition mechanism is plausible. Thus, the potential of an unsubstituted EBX reagent for the synthesis of heterocycles from complex molecules and their functionalization with mild nucleophiles was demonstrated.

Published: February 2022

Certain cyanobacteria of the secondary metabolite-rich order Nostocales can establish permanent symbioses with a large number of cycads, by accumulating in their coralloid roots and shifting their metabolism to dinitrogen fixa-tion. Here, we report the discovery of two novel lipoglycopeptides, desmamides A (1) and B (2), together with their aglycone desmamide C (3), from the nostocalean cyanobacterium Desmonostoc muscorum LEGE 12446 isolated from a cycad (Cycas revoluta) coralloid root. The chemical structures of the compounds were elucidated using a combination of 1D and 2D Nuclear Magnetic Resonance (NMR) spectroscopy and Mass Spectrometry (MS). The desmamides are decapeptides, featuring O-glycosylation of tyrosine (in 1 and 2) and an unusual 3,5-dihydroxy-2-methyldecanoic acid residue. The biosynthesis of the desmamides was studied by substrate feeding experiments and bioinformatics. We describe herein the dsm biosynthetic gene cluster (BGC) and propose it to be associated with desmamide production. The discovery of this class of very abundant (>1.5% d.w.) bacterial lipoglycopeptides paves the way for exploration of their potential role in root endosymbiosis.

Comparison of GAN Deep Learning Methods for Underwater Optical Image Enhancement
Authors: Kim Hong-Gi , Seo Jung-Min , Kim Soo Mee
Published: February 2022

Underwater optical images face various limitations that degrade the image quality compared with optical images taken in our atmosphere. Attenuation according to the wavelength of light and reflection by very small floating objects cause low contrast, blurry clarity, and color degradation in underwater images. We constructed an image data of the Korean sea and enhanced it by learning the characteristics of underwater images using the deep learning techniques of CycleGAN (cycle-consistent adversarial network), UGAN (underwater GAN), FUnIE-GAN (fast underwater image enhancement GAN). In addition, the underwater optical image was enhanced using the image processing technique of Image Fusion. For a quantitative performance comparison, UIQM (underwater image quality measure), which evaluates the performance of the enhancement in terms of colorfulness, sharpness, and contrast, and UCIQE (underwater color image quality evaluation), which evaluates the performance in terms of chroma, luminance, and saturation were calculated. For 100 underwater images taken in Korean seas, the average UIQMs of CycleGAN, UGAN, and FUnIE-GAN were 3.91, 3.42, and 2.66, respectively, and the average UCIQEs were measured to be 29.9, 26.77, and 22.88, respectively. The average UIQM and UCIQE of Image Fusion were 3.63 and 23.59, respectively. CycleGAN and UGAN qualitatively and quantitatively improved the image quality in various underwater environments, and FUnIE-GAN had performance differences depending on the underwater environment. Image Fusion showed good performance in terms of color correction and sharpness enhancement. It is expected that this method can be used for monitoring underwater works and the autonomous operation of unmanned vehicles by improving the visibility of underwater situations more accurately.
Funkkis Mökkis. Paper Huts at the 1932 Enso-Gutzeit Competition in Finland
Authors: Nieto Fernández Fernando , Rubio Hernández Rosana , Miettinen Mari-Sohvi
Published: February 2022

Finland lived, in the 1920s and 1930s, through an ephemeral time of peace and enthusiastic ideas in which it began to forge itself as a modern nation. Its borders still unstable, the country used its landscape as a social unifier and an element of national identity. Finland’s incipient welfare state, institutionalised holidays and the democratised consumer goods encouraged a new leisure lifestyle in natural settings. This article studies the recreational housing programme that responded to that demand. The new typology, later called mökki in Finland, was developed during the rise of Nordic functionalism (funkkis in Finnish) – the revision of the romantic villa and the traditional rural housing model, together with the emergence of prefabrication techniques. Among the architectural competitions and drawing albums published on the subject, this article studies the competition run by the Enso-Gutzeit paper company in 1932. Other studies have analysed this competition from constructive, stylistic or historical perspectives. This paper provides a different view by explaining that the competition was a testing ground where one of modern Finnish architecture’s distinctive features was forged: tuning into a constructed idea of nature. This fact is revealed through a graphical analysis of the competition’s proposals, as well as through the incipient personal traits in the work of the promising, young Finnish architects who participated in the competition.
La estética de lo doméstico. Olmsted y la relación entre casa y paisaje en los Estados Unidos del XIX
Authors: Mariné Nicolas
Published: February 2022

Durante las primeras décadas del siglo XIX, en los Estados Unidos la casa sirvió como elemento de mediación tanto física como intelectual con un entorno por definir en un país por definir. Por iniciativa individual, cientos de familias se fueron mudando a las periferias urbanas para construir allí su hogar y dar lugar a un modo de vida particular para la clase media. Poco tardaron entonces en aparecer promociones de viviendas unifamiliares en los aledaños de importantes ciudades. Una forma de asentamiento periférico que se modernizó, según varios autores, cuando Frederick Law Olmsted planeó y construyó el barrió de Riverside, a las afueras de Chicago. Muy alabado por haber sabido combinar un loteado sistemático con una estética paisajista, el proyecto incorporaba además obra pública propia de los centros urbanos.
El artículo argumenta que la aportación de Olmsted a esta relación entre casa y paisaje no fue únicamente práctica. Contaba también con una faceta retórica orientada, sobre todo, a la domesticación de los Estados Unidos. Para ello, se propone una relectura de dos de sus primeros proyectos: el Central Park de Nueva York y el nunca construido College de Berkeley. A partir de sus informes se aprecia hasta qué punto la idea del hogar motivaba su discurso paisajístico. A su vez, esto permite mostrar que una de las posturas más avanzadas de Olmsted fue el desarrollo de una categoría estética derivada de la vivienda: la estética de lo doméstico, un entendimiento del paisaje como una entidad que emergía de la casa.
Klas Anshelm: en una casa, en una calle, en un jardín
Authors: Gil Guinea Lorenzo
Published: February 2022

La casa en la que Klas Anshelm vivió y trabajó durante toda su vida era en apariencia una más entre las situadas al lado este de la avenida Kävlingevägen. Ocupaba una parcela estrecha y alargada, que se extendía hasta perderse en la densa vegetación del cementerio de Lund. Anshelm había comprado aquella casa en 1955. Era en origen una pieza pequeña, y mal conservada, de alguna forma desconectada del paisaje alrededor. En los años siguientes hasta mediados de los años 60 la casa creció, de forma frondosa y natural, como un árbol. Se transformó y se extendió hacia el jardín, incluso más allá de los límites de su parcela, hacia las casas vecinas, También el jardín se extendió hacia ella, componiendo un paisaje construido a la vez por la arquitectura y la naturaleza. La documentación encontrada en su archivo personal nos permite analizar este proceso por el cual su arquitectura, geométrica, directa y precisa, conectó de nuevo profundamente aquel lugar con el entorno urbano y cultural, con la tradición, y con la naturaleza cercana de la que tomó con el tiempo su misma apariencia salvaje, sencilla y primitiva. Mientras, en esos años, la ciudad creció. El tráfico en la avenida aumentó considerablemente. En 1965 el Ayuntamiento decidió ensanchar la calzada. La ampliación de la avenida dejó al descubierto aquel paisaje continuo y, de alguna manera, se desvaneció. Y Anshelm comenzó a buscar otro lugar para vivir.

THE IMPACT OF VARIABLE INCUBATION TEMPERATURE ON THE GROWTH AND METABOLISM OF EGG CROSS CHICKEN EMBRYOS AND THE DEVELOPMENT OF THEIR VISCERAL ORGANS

Published: February 2022

The article discusses issues related to the impact of variable incubation temperature (37.8°C – from the 1st to the 14th day; 39.5°C, two hours daily, in the 15th-17th days; 37.5°C – 18th day; 37.0°C – 19th-21st day; relative humidity is 57.0%) on the growth and metabolic rates of the Hysex Brown and Lohmann Brown crosses chicken embryos as well as on the development of their visceral organs and the incubation effectiveness itself. Currently, most of the research is devoted to studying the influence of variable egg incubation temperatures while using one cross of chickens and comparison with the standard incubation mode. A necessary condition for the balanced development of productive bird embryos is the acquisition of knowledge about their morphophysiological parameters and metabolic needs, based on which it is possible to adjust regimes of artificial egg incubation. The research results have shown that the developed and tested incubation regime with variable temperatures is most effective for hen eggs of the Lohmann Brown cross compared to the Hysex Brown cross. This positive effect was expressed in a more intensive growth of chicken embryos and the development of some visceral organs (gizzard stomach, spleen), as well as in the most pronounced rate of gas exchange (CO2), the highest energy value of embryos and the lowest total energy consumption for growth and metabolism in the period from 4 days of incubation to the hatching time. Differentiation of the temperature regime during embryogenesis has a positive effect on incubation results. The percentage of withdrawal of the Lohmann Brown cross young chickens is 4% higher than that of the Hysex Brown cross due to decreased embryonic mortality and decreased number of frozen embryos and suffocated chickens. This kind of research, in our opinion, is an auspicious one, and it is necessary to adjust the existing incubation regimes of hen eggs in various production areas.
ANATOMO-DIAGNOSTIC TRAITS OF LEMON LEAVES (CITRUS LIMON (L.) BURM. F.)

Published: February 2022

The article summarizes the results of studying the anatomical structure of the leaves of a medicinal lemon plant (Citrus limon (L.) Burm. f.) from the Rutaceae family, which is used in the pharmaceutical industry to produce valuable lemon essential oil with antibacterial and antioxidant properties. There is no complete information about the anatomical structure of lemon leaves in the literature, which makes it challenging to conduct microdiagnosis of medicinal raw materials. Therefore, the study of the anatomical features of lemon leaves is relevant. The researchers took the medicinal plant material of the fresh leaves of Citrus limon from the greenhouse of the Botanical Garden named after S.I. Rostovtsev. They carried out anatomical analysis of raw materials and histochemical reactions according to the regulatory documentation of the State Pharmacopoeia of the Russian Federation. The microscopic structure showed that the leaves of Citrus limon are dorsoventral, the leaf blade is hypostomatic. The stomatal apparatus of the leaves is anomocytic. In the leaf, endogenous secretory structures were observed, represented by round-shaped lysigenic essential oil receptacles formed in the columnar and spongy mesophyll of the leaf and the main petiole parenchyma. The essential oil was synthesized in the secretory cells of the receptacle, which eventually underwent autolysis and released contents into the resulting cavity. A collateral conductive bundle with a ring-shaped cross-section represents the central vein of the leaf blade and leaf petiole. The characteristic marker features of the leaf also include the presence of single rhomboid crystals and drusen calcium oxalate in the leaf petiole mesophyll and parenchyma. As a result of the studies, significant anatomical and diagnostic signs of Citrus limon leaves were found, which can be used in writing pharmacopeia articles.
UNDERESTIMATION OF INFORMATION COSTS: CAUSES AND CONSEQUENCES
Authors:   Timirâzevskaâ selʹskohozâjstvennaâ akademiâ, SVETLOV N.M.
Published: February 2022

The article summarizes the experience gained in empirical research and theoretical analysis of information costs conducted by the author. The main conclusion is that information costs are systematically underestimated. That is why the high national economic efficiency of digitalization projects often turns out to be illusory. In support of the conclusion, it substantiates the regularity of the increase in per-unit direct information costs as the volume of data collected by an economic entity grows and explains why microprocessor technologies cannot reverse this trend. Without denying the possible benefits of digitalization, the article draws attention to selected examples of situations where underestimating or neglecting information costs cause serious problems. Among them are negative information externalities, i.e., forcing information providers to bear uncompensated information costs; limited ability to apply the cost accounting principle to assess direct and especially alternative information costs; the limited competitive niche of the agricultural extension service as an intermediary in the implementation of digitalization projects; obstacles to the improvement of operational management based on the use of economic mathematical models (using field cultivation as a case) due to the prohibitively high costs of collecting and presenting data. Case studies are accompanied by suggestions that can potentially mitigate the problem.

Increasing the profitability in the maral breeding industry primarily depends on the rational and focused rearing of young animals. The development of marals at an early age largely determines the additional economic value of these animals. The study’s objective is to assess the productive qualities of maral fawns of the Novotalitskaya line of the Altay-Sayan breed. The work was carried out at the maral farms (Pokrovka, Sentelek, and Aba) of the Experiment Station “Novotalitskoe” at “Federal Altai Scientific Center for Agrobiotechnologies during the period of velvet antler cutting in July 2020. The researchers assessed two hundred sixty-six fawns having their first antlers. They found that the average velvet antler productivity among the fawns of the Novotalitskaya line was 1.5±0.03 kg. The velvet antlers had the following parameters: trunk length – 35.8±0.41 cm, trunk girth – 12.4±0.08 cm, supraorbital process length – 16.1±0.30 cm, icy process length – 15.0±0.36 cm, middle process length – 11.1±0.32 cm, bifurcation depth – 1.9±0.07 cm. 84.7% of the fawns had round antlers, 9.0% had boot-shaped antlers, and 6.3% had fork-shaped antlers. Fawn quality classification is the following: first class – 9.4%, second class – 65.4%, third class – 25.2%.

Two studies used incubation eggs of 26–40-week-old meat and egg autosex chickens of “Dominant CZ” crosses – “D-104”, “D-107”, “D-149”, “D-192”, kept in cages. Eggs were incubated in the incubators “Stimul IP-16M” and “Stimul IV-16M” by the standard regime, turning the eggs at 43–45 degrees every 45 min. Study 1 used 699894 eggs with a storage period of 2–8 days (control trays contained 22923 eggs). Study 2 used 2016 eggs after storage for four and eight days. During the 15-week productive period, the egg production intensity of the “D-192” cross was greater than the “D-104” cross by only 0.6%, and the “D-107” and “D-149” – by 2.6% and 3.0%, respectively. In the peak and post-peak phases of the productive period, the suitability of eggs for incubation from chickens cross “D-104” compared to other crosses was greater by 0.1–2.2%. According to the output of chickens parent flock of crosses “Dominant CZ” in technological and feeding conditions of LLC “Agrokormservis Plus” corresponds to the minimum requirement for breeding egg chickens with brown shells – it was 78.0%. In the middle of the pre-breeding period (6–18 days),embryo mortality was slightly higher in eggs of “D-107” and “D-192” hens (by 1.58 and 1.98%, respectively), but, on the contrary, lower in eggs of “D-104” and “D-149” hens (by 0.20%) or on average more by 0.79%. The difference between the hatch in the control trays and, in general, for all batches of eggs for crosses “D-104”, “D-149”, and “D-192” was in the range of –0.1 to +0.3%, but for the cross “D-107” – more +1.8%. On average, for the entire array of eggs, the difference was +1.0%. When storing eggs “Dominant CZ” for more than four days, the hatch of young animals decreases by an average of 1.0% per day due to increased mortality of embryos at all ages. Given the different sizes of the batch of eggs from some chicken crosses, from 35 to 180 pcs. of waste incubation (2–3% of the party) from the control trays can be opened for reliable analysis.

В последнем десятилетии большое количество публикаций посвящено применению пленок фталоцианинов металлов (MPc) в качестве полупроводниковых слоев в органических полевых транзисторах, диодах и химических сенсорах. Возможности использования фталоцианинов металлов в качестве полупроводниковых материалов определяются способом и условиями нанесения материала на подложку для получения упорядоченных структур с высоким значением проводимости и подвижности носителей заряда, которые, в свою очередь, зависят от структурных особенностей пленок, а именно фазового состава, ориентации и морфологии поверхности. В данном обзоре представлен анализ научных работ, посвященных исследованию влияния структуры и морфологии тонких пленок MPc, полученных методом физического осаждения из газовой фазы, на их электрофизические свойства, за последние десять лет.
Состав, структура и функциональные свойства тонких пленок нитрида кремния, выращенных атомно-слоевым осаждением для применения в микроэлектронике (Обзор 25 лет исследований)
Authors: Васильев В.Ю.
Published: February 2022

Рассмотрены итоги исследований 25 лет состава, структуры и основных функциональных свойств тонких пленок нитрида кремния (SiNx), полученных атомно-слоевым осаждением (Atomic Layer Deposition, ALD), применительно к задачам технологий микроэлектроники. Скорости осаждения пленок SiNx для большинства исследованных процессов в интервале температур 200—600 °С по порядку величин соответствовали 0.1 нм/цикл для двух- и трехстадийных процессов с участием прекурсоров из групп хлорсиланов, силанов, аминосиланов, силиламинов, циклосилазанов и различных вторых реагентов (NH3, N2H4, H2, N2 и их комбинации). Для исследований пленок SiNx использовали методы XPS, RBS, FTIR, AES, AFM и др. Обсуждаемые схемы процессов роста подразумевали наличие поверхностных групп NH и NH2. Плазменная активация азотсодержащих реагентов необходима при подготовке поверхности растущей пленки SiNx для начала хемосорбции прекурсора на последующем цикле осаждения и позволяет на несколько порядков величин снизить дозы прекурсоров. В процессах с плазменной активацией при участии хлорсиланов возможно формирование неприемлемых неоднородных по свойствам конформных по толщине пленок на боковых поверхностях сложных ступенчатых рельефов микроэлектронных приборов. Наилучшие характеристики по стехиометричности, составу и свойствам пленок SiNx наблюдались для температур осаждения выше примерно 500 °С для процессов как с термической, так и с плазменной активацией. Сделан вывод о необходимости глубокого систематического обзорного исследования экспериментальных публикаций по плазмоактивированному ALD тонких пленок нитрида кремния, а также их составу, структуре и свойствам.

Background

The role of children in the transmission of SARS-CoV-2 during the early pandemic was unclear.

Aim

We aimed to review studies on the transmission of SARS-CoV-2 by children during the early pandemic.

Methods

We searched MEDLINE, Embase, the Cochrane Library, Europe PubMed Central and the preprint servers medRxiv and bioRxiv from 30 December 2019 to 10 August 2020. We assessed the quality of included studies using a series of questions adapted from related tools. We provide a narrative synthesis of the results.

Results

We identified 28 studies from 17 countries. Ten of 19 studies on household and close contact transmission reported low rates of child-to-adult or child-to-child transmission. Six studies investigated transmission of SARS-CoV-2 in educational settings, with three studies reporting 183 cases from 14,003 close contacts who may have contracted COVID-19 from children index cases at their schools. Three mathematical modelling studies estimated that children were less likely to infect others than adults. All studies were of low to moderate quality.

Conclusions

During the early pandemic, it appeared that children were not substantially contributing to household transmission of SARS-CoV-2. School-based studies indicated that transmission rates in this setting were low. Large-scale studies of transmission chains using data collected from contact tracing and serological studies detecting past evidence of infection would be needed to verify our findings.

On 5 January 2022, high pathogenicity avian influenza A(H5N1) was confirmed in an individual who kept a large flock of ducks at their home in England. The individual remained asymptomatic. H5N1 was confirmed in 19/20 sampled live birds on 22 December 2021. Comprehensive contact tracing (n = 11) revealed no additional primary cases or secondary transmissions. Active surveillance of exposed individuals is essential for case identification. Asymptomatic swabbing helped refine public health risk assessment and facilitated case management given changes in avian influenza epidemiology.

Development planning itself can be said as an alternative to the government in carrying out the task of realizing a change in certain areas to be able to catch up with other regions. The application of innovation aims to develop a renewal involving several stakeholders. Ecotourism is an innovation that can be applied in promoting development planning in a real context. The purpose of this research is to find out the scientific trend about development planning ecotourism by using bibliometric analysis through the VOSviewer application. This research uses qualitative research with a literature review approach. The results consist of mapping and clustering the results of previous research in the form of image visualization media with network and density mapping. Projections of development planning by creating ecotourism-based innovations have been carried out in various parts of the world. The existence of development and its linkage with the tourism sector makes a positive impact on people's lives, especially rural communities. Limitations of this study is that only correlations on the existence of development in the tourism sector are presented.

The declaration of the omnibus law reaped the pros and cons in the community. In a situation like this, the media should be neutral. One of the media that still maintains neutrality is Detik (Rumata 2017). Detik owns several channels such as detikNews, detikFinance, and CNN Indonesia. In this study, the neutrality of the CNN Indonesia media as part of Detik will be studied based on the tendency of sentiment on the omnibus law-related news. Sentiment analysis is used to examine the trend of opinion on news headlines. In conducting sentiment analysis, a method that supports classification is needed. The classification method that will be used in this research is the Support Vector Machine (SVM). There is an imbalance of data in the three categories of sentiment so that the Synthetic Minority Oversampling Technique (SMOTE) method is used to overcome this imbalance. The omnibus law tends to be reported neutrally by CNNIndonesia.com site. The one vs all method has a better classification result than the one vs one method. The application of SMOTE only gives slightly better results than data classification without the application of SMOTE because the imbalance in the data is not too extreme. Modeling using the one vs all method with SMOTE and distribution of data 90% train data 10% test data gives the best classification results with a macro average f1-score of 60,33%.
