Judical Restraint Kewenangan Badan Pengawas Pemilu Pasca Penetapan Hasil Perolehan Suara Secara Nasional
Authors: Megita Vina Septi , Ilmiyah Zainatul
Published: August 2023

Salah satu syarat utama pemerintahan yang demokratis adalah adanya pemilu yang bebas dan tidak memihak. Berkenaan dengan Badan Pengawas Pemilu (Bawaslu) yang di satu sisi  menjalankan  fungsi  pengawasan  pemilu, dan di sisi lain mengadili pelanggaran pemilu apabila dilihat dari segi kelembagaan negara, maka dapat berpotensi munculnya abuse of power dalam suatu lembaga. Selain itu dengan adanya kewenangan mengadili pelanggaran administrasi pemilu khususnya pada proses perhitungan suara sering kali menimbulkan tumpang tindih kewenangan antara Bawaslu dan Mahkamah Konstitusi. Sehingga penelitian ini bertujuan untuk mengoptimalkan fungsi kewenangan Bawaslu agar terciptanya pemilu yang demokratis. Berdasarkan metode penelitian yuridis normatif dengan pendekatan perundangan-undangan (statute approach), pendekatan konsep (conceptual approach), dan pendekatan kasus (case approach), dalam penelitian ini ditemukan bahwa dalam kasus pelanggaran pemilu yang baru dilaporkan dan diregistrasi oleh Bawaslu setelah adanya Penetapan Hasil Perolehan Suara secara Nasional oleh Komisi Pemilihan Umum (KPU), mengakibatkan tumpang tindih kewenangan penyelesaian. Hal ini dikarenakan pelanggaran dan atau kesalahan dalam pelaksanaan rekapitulasi yang ditangani oleh Bawaslu dan berdampak pada hasil, hal tersebut merupakan kewenangan Mahkamah Konstitusi. Sehingga konsep Judicial Restraint sebagai upaya pembatasan yudisial kewenangan yang dimiliki Bawaslu dalam menyelesaikan pelanggaran pemilu diperlukan dalam upaya mewujudkan pemilihan umum yang demokratis.  Sehingga dalam memutus pelanggaran pemilu dan sengketa proses pemilu perlu dibentuk Pengadilan khusus pemilu.
Tindak Pidana Human Trafficking Perspektif Hukum Pidana Islam
Authors: Nur Rahmawati Syahdila
Published: August 2023

Artikel ini disusun untuk membahas mengenai tindak pidana perdagangan orang atau lazim dengan TPPO. Human trafficking ini masuk dalam kategori hukum pidana khusus,yang di Indonesia diatur dalam UU No.21 Tahun 2007.  Indonesia sendiri merupakan negara hukum yang segala perbuatan diatur oleh hukum dan menjujung juga adanya hak asasi manusia. HAM tersebut harus dipenuhi dan tidak boleh dilanggar. Oleh karena itu terdapat pengaturan sanksi mengenai TPPO menurut hukum positif yang ada di Indonesia dan pengaturan sanksi mengenai TPPO menurut hukum pidana islam. Sehingga artikel ini memiliki tujuan yaitu untuk menganalisis bagaimana kedua hukum tersebut mengatur mengenai TPPO ini. Artikel ini pula disusun berdasarkan studi pustaka, dimana penulis melakukan pendekatan dengan berbagai sumber literatur seperti buku, jurnal hukum. Dan peraturan perundang-undangan yang berhubungan dengan TPPO. Dalam hukum positif sendiri, TPPO diatur dengan melihat UU No. 21 Tahun 2007 juga dalam KUHP. Sedangkan dalam hukum pidana islam sendiri, TPPO ini sebenarnya sudah dilakuka sejak zaman jahiliyah namun merujuknya pada perbudakan. Dalam hukum pidana islam sendiri TPPO masuk dalam kategori jarimah ta’zir.

Effect of surcharge loads during curing of lime-stabilised Cochin marine clay
Authors: Johny Rija , Abraham Benny Mathews , Sridharan Asuri
Published: August 2023

Marine clays possess poor engineering properties and need to be improved prior to any construction activities. Lime stabilisation is a widely adopted method of chemical stabilisation for such types of soils. This paper evaluates the effect of surcharge loads during curing of lime stabilisation of Cochin marine clays. In the case of lime-stabilised soil cured under surcharge loads, it is necessary to consider two processes – that is, cementation and consolidation—along which the structures of stabilised soils evolve. These two processes are interrelated and cannot be considered separately, especially in the early stages of curing when significant structural changes occur. This study investigated the strength and deformation characteristics of lime-stabilised Cochin marine clay subjected to surcharge loading during curing. The marine clay with 6% lime was subjected to surcharge loads of 20, 40 and 60 kPa for different curing periods up to 180 days. The effects of surcharge loading on shear strength and compressibility characteristics were evaluated at different curing periods.
Incidencia del Entendimiento de Solución de Diferencias de la OMC en la normativa de propiedad intelectual de los procesos de integración regional: Informe
Authors: Santiago Deluca
Published: August 2023

In this research we analyze the impact of the rulings of the Appellate Body of the Dispute Settlement Understanding of the World Trade Organization (WTO) on intellectual property, with respect to the new rules of origin and secondary legislation adopted in regional integration processes in the period 2000 to 2019. From this general perspective, three hypotheses are examined. The first is that the intellectual property disputes between States that reached the WTO found a solution that was sustained over time. Second, that the disputing countries complied with the Appellate Body reports, even when they disagreed. And third, that the legislation of the regional integration processes positively received the DSU's precedents. To verify these approaches, the organization of international economic law and its relationship with regional integration processes is analyzed. Then, the methodology for dispute settlement in these spaces, as well as the form of normative elaboration -original and derived- are analyzed. Next, the quantification of the WTO's DSU pronouncements -reports- on intellectual property was established. And finally, the impact of compliance with and reception of these reports in the new regulations drawn up by the integration processes was evaluated, using graphs that allow for the correct visualization of the impact to be demonstrated. This led to objective conclusions, although in some cases contrary to the research hypotheses.
Features of formation of the Al–Ni–Zr system alloy structure obtained by reducing oxide compounds by aluminothermy using SHS metallurgy
Authors: Ri Kh. , Ri E. Kh. , Ermakov M. A. , Kim E. D.
Published: August 2023

This work is focused on establishing the regularity of the effect of zirconium (2.21; 3.29; 3.69 and 6.92 wt.% Zr) on structure formation, the nature of distribution of elements and the microhardness of structural components in the Al–Ni–Zr system alloys obtained by aluminothermy using the SHS metallurgy. Regularities of the formation of structural components and their microhardness depending on the content of zirconium in Al–Ni alloys (50 wt.%) have been identified and scientifically substantiated. Structural components were identified by the methods of electromicroscopic studies and X-ray microanalysis of elements. The structure of the initial alloy consists of Al3Ni2 (β′-phase) and Al3Ni nickel aluminides. Zirconium doping of the alloy in the amount of 2.21 wt.% leads to crystallization of zirconium nickel aluminide Al2(Ni,Zr). With further increase in the content of zirconium (more than 2.21 wt.% Zr), complex alloyed intermetallic compounds crystallize – Zr, W, Si aluminides and Ni zirconides. A regularity was established in the decrease of the solubility of nickel in nickel aluminides Al3Ni2 and Al3Ni and their microhardness as the zirconium content increases in the Al–Ni–Zr alloys from 2.21 to 6.92 wt.%. In nickel aluminide with zirconium Al2(Ni,Zr), this contributes to a decrease in the solubility of Ni, Al and increase in the concentration of Si and Zr. Zirconium doping of the Al–Ni alloy in the amount over 2.21 wt.% contributes to an increase in hardness (HRA), despite a decrease in the microhardness of the metal base (Al3Ni2, Al3Ni and Al2(Ni,Zr)). The main reason for increasing the hardness of the Al–Ni–Zr alloys is the crystallization of complex-alloyed intermetallides – Zr, W, Si aluminides and nickel zirconide, which probably have an increased microhardness. Thus, zirconium doping of the Al–Ni alloy makes it possible to obtain a plastic metal base from nickel aluminides Al3Ni2, Al3Ni and Al2(Ni,Zr) and complex-alloyed intermetallides with high hardness.
Sputtering by inverted magnetrons: influence on the texture and residual stresses in four layer Ta/W/Ta/W coatings

Published: August 2023

The aim of the study is to examine the possibilities of sputtering of multilayer coatings at a high rate of deposition on products of complex shape using inverted magnetrons. The formation of texture and residual stresses in magnetron four-layer Ta/W/Ta/W coatings deposited at voltages from 0 to –200 V on cylindrical and flat copper substrates imitating elements of the surface of complex shape products was evaluated using the X-ray method of inverse pole figures and the sin2Ψ method. The patterns of texture formation in coatings depend mainly on the bias voltage on the substrate (Us), while at Us = –200 V they differ for W and Ta layers. At Us = –100 V, the epitaxial mechanism of texture formation is realized. In the case of a cylindrical substrate, this leads to intense texture (111) of all four layers. In the case of a flat substrate, this can lead to the formation of a single-crystal texture (111) in all layers with a texture maximum width of 12°–14°. The presence of a single-crystal (111) tantalum texture corresponds to the maximum Young moduli and, accordingly, the interatomic bonding forces normal to the coating plane. This suggests that multilayer coatings with an external Ta layer have high tribological characteristics. Increasing the voltage on a flat substrate from 0 to –200 V leads to an increase in residual compressive stresses from 0.5 to 2.7 GPa for the four-layer coating under study.

[RETRACTED]

This document is highly theoretical lab method paper. It may be used to perform thermogenesis from several cells in a living organism instead of only brown adipocytes. We perform thermogenesis from white adipocytes. The purpose is to uptake the blood glucose and lipids to produce heat and subsequent weight loss and to diminish blood glucose levels for people who suffering from diabetes and obesity. In fact thermogenesis consumes energy (i.e blood glucose and blood lipids). So we now describe a novel and original lab method based on thermogenin (called thermogenin-like system, UCP1-like system or TLS) that is involved in heat production and glucose/lipids capture by white adipocytes.

Thunder and lightning without rain
Authors: Chifungo Davidson
Published: August 2023

Today in the African context in general and Malawi in particular there has been a proliferation of preachers, prophets, bishops and local pastors whose preaching leaves a lot to be desired. The majority of the popular sermons demonstrate a lack in proper biblical understanding. Yet the preachers feel called to preach and teach the word of God. This article therefore aims at evaluating and analysing sermons of the preachers in the church. But due to an apparent lack of formal Bible literacy lessons the sermons lack biblical understanding and therefore this status affects the spiritual growth of the majority of the congregants. It is like we have a lot of thunder and lightning, but if you do not have the rain nothing grows on the ground. Preaching must break through the bad cultural practices, like Jesus who unsettled the Jewish culture and turned it upside-down in His teaching. We should be willing to be preaching fools. Therefore, in this article we are suggesting a homiletical theory and praxis which regards the biblical text and the people's context "Word and world"as serious.
Preaching as "Commercialised Pavement Spirituality"
Authors: Louw Daniël
Published: August 2023

The Africanisation of Christianity is indeed a challenging endeavour. It is difficult to pin point what is exactly meant by an African version of the Christian faith. Many attempts to make Christianity "indigenous" are merely a European version with an African flavour. The article probes into the informal life settings of township spirituality. Unemployment and poverty demarcate the structural conditions of township life. The phenomenon of spaza entrepreneurship is investigated, specifically how naming of informal street businesses, often reflects a kind of internalised Christian spirituality. Spaza is the Zulu word for camouflage. With "spaza" piety is meant: Faith in Cognito; faith operating within the disguise of faithful businesses where poor and unemployed people try to survive the hardships of poverty and unemployment. "Spaza spirituality" is rendered as a kind of streetwise "sermon". At stake within the discipline of homiletics is the following questions: When the context becomes the text, what is meant by "contextual preaching" within township life? Can the Christian faith indeed beautify township life so that practical theology implies more than ethical endeavours but includes an aesthetic ecclesiology: Fides quaerens beatitudinem (faith seeking the beautification of life).
art of preaching
Authors: Meyer Ockert
Published: August 2023

"An orator", Cicero famously said, "is a good man, trained in the art to speak well." The difference between orators and actors, he continues, is that orators are "players that act real life" whereas, actors are "players who only mimic reality".Preaching is not only an oratorical skill but also a theological art. All of this suggests a deep awareness and sensitivity to aesthetics. Both preachers (or orators) and actors usually have, or should have, something of this sensitivity. Both preachers and actors are intent on weaving words into patterns that both make sense and stimulate the senses. The often-quoted idea that"beauty will save the world" (from Dostoevsky's The Idiot) feeds into a perception that somehow aesthetics in itself has some or other redemptive quality. Or translated into the context of preaching: that it will somehow by itself elevate, enhance or redeem the act of preaching. There is no doubt that this idea is a misrepresentation of what Dostoevsky had in mind. The decisive factor in preaching is not the reality of beauty but the beauty of reality. Both preaching and beauty are deeply grounded in reality. However, preaching as a theological art is not only grounded in the reality as our senses experience it, but more so in the reality of Jesus Christ.

This chapter, in honour of Johan Cilliers, will not seek to engage his extensive oeuvre, but rather focus on a single text (2011), Fides Quaerens pulchrum: Practical theological perspectives on the desire for beauty, which I believe encapsulates something of Johan Cilliers' passion as well as fits into the theme of this volume. From his article certain key terms or even themes can be identified. I will engage these key themes by bringing them into conversation with the thoughts of Lacan and Hegel, and thereby enter into a conversation with his article and honour his thought. The key themes that I have identified from this article are the following: beauty, imagination, art, art theory, aesthetics, Ästhetik des Hässlichen, Negativschönen, desire, the good, and lastly the consequences of these various concepts for practical theology.

BLOCK MODEL OPTIMIZATION AND RESOURCE ESTIMATION OF THE ANGOURAN MINE BY TRANSFERRING THE EXPLORATORY DATA FROM THE LOCAL COORDINATE SYSTEM TO THE UTM
Authors: Rezaei Mohammad , Fallahi Siavash
Published: August 2023

Resource estimation is one of the most important steps in the mining process. Precise resource estimation has a significant influence on the optimization of subsequent mining steps, i.e. mine planning and scheduling. The previous resource estimation in the Angouran Mine was conducted based on the provided information in the local coordinate system which causes considerable errors in estimations. Therefore, an attempt is made in this research to optimize the block model of the Angouran Mine and resource estimation based on the information in the UTM global coordinate system. For this purpose, exploratory data is firstly transferred from the local coordinate system to the UTM environment. Then, block model optimization is conducted using indicator kriging (IK) in which the waste blocks are removed and the block model was optimized. Finally, resource estimation is performed using the inverse distance weighting (IDW) and simple kriging (SK) methods. After variogram analyses in different directions, it was found that the mine deposit is anisotropic. Also, validation results showed that the acquired correlation coefficient in the carbonate and sulfide sections for IDW, SK and IK is 0.86, 0.87 and 0.92, and 0.88, 0.87 and 0.92, respectively. Finally, the obtained grades and tonnages are compared with the actual data of the exploratory boreholes, mined blocks and previous resource estimation in the mine. Comparative results showed that the obtained grades and tonnages from both previous and new models are over-estimated and higher than the actual values. The minimum errors of grade estimation equal 46% and 23.1% for previous and new resource estimations (before and after the waste removal), respectively. Also, the mining errors of tonnage estimation are 50.29% and 28.37% for previous and new models, respectively. This field comparison proved that transferring the exploratory data to the UTM system, utilization of the IK to remove the waste blocks and applying the SK for resource estimation lead to the optimization of the block model and a reduction in the estimation error compared to the previous estimations for the mine.

Published: August 2023

Since the establishment of the International GNSS Service (IGS) stations, they have been used as control stations for assigning the Precise point positioning (PPP) positions using one Global Navigation Satellite System (GNSS) receiver, which has increased from day-to-day. There are some factors affecting the accuracy of PPP positioning. This research aims to investigate the relation between the IGS distance and observed field points as well as to attempt to describe that relation mathematically/statically. For the realization of that aim, two field points are fixed inside the Assiut University campus and observed successively for a session of 24 hour observation. The position of each field point is assigned with the help of each one of the available IGS station products. It must be known that these products are found after observations in three files (IGU, IGR, and final IGS), whereas IGU is used directly as real-time data (ultra-rapid), IGR (rapid) is used through (17-41 hours) after observation, and (final IGS) used after 12 – 18 days. Coordinates and point errors of each field points are computed and represented. It has been found that the errors have a positive relation with the available IGS stations distances. The relation between these distances and point positioning errors have been represented and described according to a model. The accuracy of the presented model is (R ≅ .98, x2 ≅ 2.5 × 10-3).

BACKGROUND: Myocarditis is among the most common complications arising from coronavirus infection (COVID-19).
AIM: This study aims to find the differences in the patterns of myocardial injury between patients who had COVID-19 and those from the pre-pandemic period, as determined by contrast-enhanced cardiac magnetic resonance imaging.
MATERIALS AND METHODS: The study encompassed a retrospective analysis of 47 patients who underwent contrast-enhanced cardiac magnetic resonance imaging to rule out acute myocarditis. Group 1 comprised 34 patients with a confirmed history of COVID-19 through PCR testing (nasal and/or throat swabs), while Group 2 comprised 13 individuals who underwent contrast-enhanced cardiac magnetic resonance imaging in 2017 prior to the onset of the COVID-19 pandemic. All patients enrolled in the study had clinical manifestation of cardiac injury without signs of coronary artery disease as an underlying cause of condition.
RESULTS: The mean time from the onset of heart symptoms to the administration of contrast-enhanced cardiac magnetic resonance imaging was 166 days. In group 1, a decrease in exercise tolerance was observed in 77% of patients, and 14 (42%), 30 (88%), and 28 (85%) of patients complained of chest pain, shortness of breath, and heart palpitations, respectively. In group 2, four patients (30%) had dyspnea, nine patients (69%) complained of chest pain, and six patients (46%) had heart palpitations and/or feeling of arrhythmia. Myocardial injury in group 1 was more generalized. The third of them had displayed preserved increased pulmonary vascularity and pleural effusion. Within group 1, men had significantly lower left ventricular ejection fraction, lower values of global longitudinal deformation, and higher values of left atrial function compared with the corresponding parameters in women. Differences in women were found only in the number of the affected segments in the left ventricular myocardium.
CONCLUSION: SARS-CoV-2 virus caused extended myocardial injury, affecting a significant number of myocardial segments. Men had more frequent postinflammatory complications, characterized by abnormal function of the left ventricle and left atrium. Obtained results require continuous efforts for further assessment of long-term consequences of previous COVID-19 to the cardiovascular system. In this regard, contrast-enhanced cardiac magnetic resonance imaging may represent a sensitive imaging tool for the assessment of cardiac injury severity.

The bullet, which is activated by the firing of the gunpowder in the gun silencer, comes out of the gun's barrel. In the meantime, an irritating muzzle blast sound is heard that lasts for a few milliseconds. With this explosion, acoustic sound waves are formed that are independent of the bullet's path of motion. In this study, a silencer that can be attached to a low-power 9 mm firearm is modeled. Afterward, the impact of holes with the same area drilled in different geometries and angles on the diffusers (compartments) of the silencer are compared. The Computational Fluid Dynamics (CFD) analysis method is used for this comparison. In addition, the dynamic mesh model is used where the ballistic field changes over time. This mesh model is analyzed for imperforate, circular-holed, square-holed, and triangular-holed profiles with the same area. Depending on the analyses, the pressure, velocity, and dB results obtained for the silencer outlet area are compared with each other.

The results of Riskesdas (Baseline Health Research) by the Indonesian Ministry of Health in 2018 revealed that the caries rate in rural areas was higher than in urban areas. However, the number of villagers receiving dental and oral health care was lower than in urban communities. Karangtengah Village was located in the Baturraden District, Banyumas Regency, which is socio-demographically rural. This study aims to determine the correlation between knowledge and affective of oral health on the caries rate in Karangtengah Village. The study was observational analytical research. Subjects were selected using a purposive sampling technique. The total subjects were 388 residents. The knowledge and affective data were collected using a questionnaire, and the caries rate was scored using DMF-T. Data were analyzed using the Pearson correlation test (SPSS 22). The results revealed that the oral health knowledge and affective of the majority of Karangtengah Village residents were in the moderate category (48.7% and 66.8%, respectively), while the average DMF-T score was 13.12 (very high). The statistical analysis demonstrated no significant correlation between knowledge and DMF-T score and between the affective aspect of oral health and DMF-T score (p0.5).  The moderate category of oral health knowledge and affective aspect in rural areas may not have been applied as oral health behaviors contribute to high dental caries rates.

Micro friction stir welding (μFSW) adalah pengelasan friction stir welding untuk ketebalan maksimal 1 mm. Tujuan penelitian adalah mengetahui pengaruh feed rate dan sudut kemiringan pin tool pada μFSW aluminium 1100. Pengelasan dilakukan dengan variasi sudut kemiringan tool 0°,1° dan 2°, dengan variasi feed rate 66, 85, dan 120 mm/menit serta kecepatan putaran pin tool 2280 rpm. Jenis sambungan yang digunakan adalah sambungan butt. Pengujian yang dilakukan adalah pengujian struktur mikro dan cacat makro dengan mikroskop optik, uji kekerasan, dan uji kekuatan tarik. Hasil pengamatan makro terdapat cacat lasan pada variasi feed rate yaitu cacat incomplete fussion. Hasil pengamatan struktur mikro menunjukkan bahwa grain size pada stir zone (SZ) semua variasi tampak lebih kecil dibandingkan pada BM dan HAZ menyebabkan nilai kekerasan pada HAZ dan SZ lebih tinggi dari pada BM. Semakin bertambah kecepatan feed rate dan sudut kemiringan tool maka kekerasan daerah SZ dan kekuatan tarik semakin meningkat. Heat input yang tinggi mengakibatkan pendinginan lebih lambat sehingga butiran lebih besar dan menyebabkan penurunan nilai kekerasan. Kekerasan tertinggi pada feed rate 120 mm/menit sebesar 73,7 VHN dan kemiringan tool 2o sebesar 64,7 VHN. Kekuatan tertinggi pada feed rate 120 mm/menit sebesar 84,84 MPa dan pada sudut kemiringan 2o sebesar 111,36 MPa. Micro friction stir welding (µFSW) is friction stir welding for a maximum thickness of 1 mm. The aim of the research was to determine the effect of the feed rate and the tilt angle of the pin tool on 1100 µFSW aluminum. Welding was carried out with variations in the angle of the tool tilt of 0°, 1° and 2°, with variations in the feed rate of 66, 85, and 120 mm/min and the pin rotation speed. tools 2280rpm. The type of connection used is the butt joint. The tests carried out were testing the microstructure and macro defects with an optical microscope, hardness test, and tensile strength test. The results of the macro test showed that there were defects in the feed rate variations, namely incomplete fusion defects. The results of microstructure testing showed that the grain size of the stir zone (SZ) of all variations was smaller than that of BM and HAZ causing the hardness values of HAZ and SZ to be higher than that of BM. As the speed of the feed rate and the angle of inclination of the tool increase, the hardness of the SZ region and the tensile strength increase. High heat input results in slower cooling resulting in larger grains and causes a decrease in hardness values. The highest hardness at a feed rate of 120 mm/minute is 73.7 VHN and the slope of the tool 2o is 64.7 VHN. The highest strength at a feed rate of 120 mm/min is 84.84 MPa and at an angle of 2o is 111.36 MPa.

Foods derived from plants are important sources of food for natural enemies and influence several functions of their existence, including reproduction. The objective of the current study was to assess the effect of different sources of food and host densities on the oviposition efficiency of key parasitoids of Spodoptera frugiperda. The experiment was set up under laboratory conditions in a completely randomized block design with three factors namely parasitoids (four), feeding (groundnut pollen, soybean nectar, honey, starved as control) and host densities (five), a total of 80 treatments. There were five replications for the experimental design while the experiment was repeated four times, a total of 20 replications for each treatment. Results showed that the functional response of adult parasitoids was influenced both by food sources and host densities. Soybean nectar worked the best like honey, followed by groundnut pollen. Soybeans and groundnut may therefore have agroecological interests beneficial for mass rearing to promote key parasitoids as biological agents to control S. frugiperda. As for the host densities, the minimum and maximum of the parasitized host were obtained respectively with the densities of 20 and 100 eggs per female for T. remus, 20 and 80 eggs for Trichogramma sp. and C. insularis and 5 to 50 larvae for C. marginiventris. Taking into account the interesting results obtained which would be favourable to the rapid multiplication of parasitoids, tests in real environments are necessary to test the influence of the main environmental factors on the performance of said parasitoids.

Chickpea (Cicer arietinum L.) is grown in more than 50 countries. India is the largest chickpea-producing country accounting for 64% of the global chickpea production. However, the production is contrained by the dry root rot disease caused by Rhizoctonia bataticola. Considering this problem, the investigation was carried out to isolate, characterize and the antagonistic potential of indigenous endophytic PGPMs for one of the components in the integrated management of dry root rot of chickpeas in eco-friendly manner. Hence, the isolation of thirty endophytic PGPMs was carried from chickpea by using the spread plate technique. The cultural characters and Gram’s staining reaction confirmed that the endophytic PGPMs isolated from chickpea plant tissues were bacteria. Among thirty bacterial strains, eight showed more than 50% of mycelial inhibition of the pathogen. Out of eight strains, five highly superior strains were selected and subjected for 16S rDNA gene sequencing using the universal primers (16Sr DNA F and 16Sr DNA R), which produced amplified products of size 1500 bp. nBLAST results of 16S rDNA gene sequence revealed that all the endophytic bacterial PGPMs showed homology with genus Bacillus but with different species. The five potential strains namely, BEPGPM-5, BEPGPM-9, BEPGPM-27, BEPGPM-28, and BEPGPM-30 were identified and confirmed as B. tropicus, B. pacificus, B. cereus, B. subtilis, respectively, based on molecular technique.

Bacillus subtilis is a Gram-positive and endospore producing bacterium. Limited studies have shown that lipopeptides produced by B. subtilis can be inhibitory to phytopathogens. Sclerotinia sclerotiorum is a plant pathogenic fungus which causes various diseases like cotton rot, watery soft rot, stem rot, crown rot and blossom blight in vegetable crops. The objective of the study was to isolate lipopeptides from B. subtilis and study their inhibitory potential against S. sclerotiorum. So, the B. subtilis isolates were extracted from the collected soils of Western Ghats of India. They were initially characterized through morphological parameters followed by PCR amplification of the 16S rDNA gene and confirmation through BLAST algorithm in NCBI database. The lipopeptides produced by these isolates were tested against S. sclerotiorum. B. subtilis strains were effective against S. sclerotiorum and exhibited 18.33 to 29.5 % inhibition under dual culture bio-assay. The antagonistic activity of lipopeptides extracted from B. subtilis strains showed 21.56 to 88.89 % inhibition of S. sclerotiorum in the lowest to highest concentration of lipopeptide tested and was found to be significantly higher than the control. The present study has shown that B. subtilis strains vary in the production of lipopeptides and some of them could produce lipopeptides that are highly inhibitory to S. sclerotiorum. B. subtilis strain NBAIR BSWG1 showed the highest inhibition for S. sclerotiorum. Lipopeptide based poison food technique and the dual culture bioassay results showed that B. subtilis strain NBAIR BSWG1 has immense potential for use in the biological control of S. sclerotiorum. Further studies are being carried out in formulating the lipopeptides for field application.
Integration of augmentative biocontrol with synthetic pesticides and other control methods for IPM – Challenges and prospects*
Authors: Manjunath T. M.
Published: August 2023

The importance of augmentative biological control and chemical control, and the need and scope for integrating these, rather than dismissing them as incompatible, so as to create a win-win situation for both are highlighted. Besides the judicious use of chemicals and periodical releases of parasitoids/predators, other options such as insect-resistant transgenic crops, host plant resistance, botanical insecticides, sex pheromones, trap crops, pest resistance management, new product development, regulatory measures, etc., should also be exploited, as appropriate to a given situation, so as to develop an Integrated Pest Management (IPM) package. The practicality of such an IPM is explained, citing Bt cotton as an example. It is reiterated that IPM is the most prudent approach for sustainable crop production and protection with the major emphasis being laid on biological control and other eco-friendly methods as indicated by the latest global trend.
