Diarrhea is a condition where the frequency of defecation occurs more than 3 times a day. One of the causes of diarrhea is a bacterial infection, so an antibacterial agent is needed to overcome the problem. One of the natural ingredients that can be utilized is Durian. Based on phytochemical screening, durian fruit skin meat contains alkaloid compounds, saponins, flavonoids and tannins which can inhibit bacterial growth. This study aimed to determine the antibacterial activity of ethanol extract of durian fruit skin flesh (Durio zibethinus Murr) against Salmonella bacteria on ATCC 14028 and Bacillus cereus ATCC 11778. This study used an experimental design, extract was obtained by maceration method. Testing of the antibacterial activity of ethanol extract using the disc diffusion method. The treatment used 15%, 20%, 25%, 30% and 35% concentrations, negative controls using distilled water and positive controls using tetracycline solution. The results showed that testing on Salmonella bacteria had good antibacterial activity up to a concentration of 30% with a diameter of 11 mm inhibition zone, whereas in Bacillus cereus bacteria at a concentration of 20% gave antibacterial activity which included a weak category with a diameter of inhibitory zone 15 mm. Based on the results of phytochemical screening of durian fruit peel extract containing secondary metabolites, namely flavonoids, alkaloids, saponins and tannins and the results of testing data on the activity it can be concluded that durian fruit flesh extract still has potential as an antibacterial agent. So it is necessary to do the next step with fractionation and isolation of other active compounds. antibacterial activity data.

Project LEARN: Climate change risk management and adaptive strategies for flood-prone communities
Authors: Mangansat Nancy Joy M.
Published: January 2025

This study evaluates the climate change awareness, attitudes, impact risks, adaptation strategies, and mitigation responses of selected households in flood-prone areas of Nueva Ecija, the Philippines. Recognizing the complex interaction between socio-demographic factors and climate risk perceptions, this study addresses gaps in understanding how education, income, and geographic differences influence adaptive behaviors (Çıplak, 2022). Furthermore, climate-induced disasters are escalating globally, with vulnerable regions experiencing disproportionate impacts (Fawzy et al., 2020). Utilizing a descriptive research design, data was gathered from 900 household heads through questionnaires, informal interviews, and observations. The findings indicate that respondents have moderate climate change awareness, with rural households showing a higher frequency of adaptation and mitigation responses due to their perceived increased risks. Based on these insights, the study proposes project LEARN, a climate literacy program designed to enhance the knowledge and resilience of communities. This research contributes to local understanding of climate change and offers actionable strategies to improve adaptation and mitigation efforts in vulnerable regions (Fawzy et al., 2020).

Authors:   Asian Development Bank, Tian Shu , Wu Yu ,   Nanjing Agricultural University, Zhou Wenwen ,   Southwestern University
Published: January 2025

This paper uses household data from the People’s Republic of China to examine how digitalization affects income inequality.
The findings indicate that digitalization significantly reduces income inequality, particularly in less-developed areas and among less-educated households. Digitalization narrows the income gap by increasing earnings more for lower-income households through improved employment and investment opportunities. It also boosts business income for entrepreneurial households. These results suggest that promoting digitalization can help reduce income inequality in developing economies.
Urbanisation, migration, depopulation and virtual ritual community - the village kurban as a shared meal
Authors: Hristov Petko , Manova Tsvetana
Published: January 2025

The paper deals with the specific use of collective rituals focused on blood
sacrifice and a shared meal among Orthodox Christians in the Balkans, known
mostly as kurban. In studying a variety of feasts, the analytical focus is
on the collective gathering and the shared meal, which is celebrated by the
small village community as its ?homeland?, a sense of belonging to a virtual
community consisting of people from all over the world. This paper pays
particular attention to examples of the collective kurban in depopulated
villages. Among migrants in big cities born in the same village, the kurban
is understood as part of a common cultural heritage and a ritual that helps
produce and/or re-produce a group identity within a broader national
framework and urban social milieu. The kurban is also perceived by the
participants as a ritual way of creating social cohesion for kinship-based
and territory-based communities, beyond confessional attachment. In a
selection of cases, the paper demonstrates how a blood sacrifice and a
shared meal, as well as the symbolic use of the patron saint of a
birthplace, recreates cohesion between the former members and the new
migrants from the city to the village.
Latin-Byzantine artistic interactions and the church of Saint Basil in Mrzep (Montenegro)
Authors: Bacci Michele
Published: January 2025

The present paper offers some thoughts on and a new interpretive frame of
the painted program of the small, single-nave church of Saint Basil in
Mrzep, in the vicinity of Donji Stoliv, in the Vrmac peninsula near Kotor,
Montenegro. This monument stands out for the abundance of available
information on its history, including the name of the painter (Mihailo), the
identity of the donor (Stefan Kalodjurdjevic) and even the date of its
construction and pictorial decoration (1451). Nevertheless, the
art-historical debate has been mostly puzzled by the melange,
Latin-Byzantine character of the painted images, which has been explained as
an outcome of the Union of the Orthodox and Roman churches declared at the
Council of Ferrara-Florence in 1438-1439. The analysis provided here
emphasizes the scarcity of indications about the impact of the latter?s
resolutions on the arts and proposes an alternative interpretation that
associates the choice of specific forms with the devotional strategies
worked by Stefan Kalodjurdjevic for his and his family?s spiritual health.
Ritual objects for the feast of sukkot: Theoretical analysis of the Talmudic prescriptions and some of their ethnographical achievements in the Balkans
Authors: Vartejanu-Joubert Madalina
Published: January 2025

Can we think of the artifact as an integral part of an anthropology of life
as it has developed in the wake of the anthropology of nature founded by
Philippe Descola? Judaism clearly fits within this perspective since a vast
body of normative texts, notably the Babylonian Talmud, defines and
discusses the jewishness of artifacts - whether ritual or everyday - by
endeavoring to determine their correct position on a graduated scale ranging
from nature to artifice, understood here as emic categories. This article
aims to support this reflection by studying two ritual objects related to
the festival of Sukkot: the skhakh, the roof of the sukka hut, and the
lulav, the bouquet of the four species. As we shall see, the making of the
ritual object according to specific rules shows us its place in the
encounter with the supernatural, the goal towards which any ritual device
aspires. After a theoretical analysis of the Talmudic prescriptions, we will
look at some of the practical ways in which the Sukkot hut can be documented
photographically in the Balkans, in the broadest sense of the term. We will
present examples from Greece, Romania and Bulgaria.

Authors: Miraglia Federico E.
Published: January 2025

This is the first part of a research work to study the reliability of the Apparatus for Meridian Identification (AMI), an electrodermal device that measures the response of acupuncture points (acupoints) located on the tips of fingers and toes. The AMI was invented by Hiroshi Motoyama, a Japanese scientist who dedicated his life to studying the bioenergetics of Traditional Chinese
Medicine (TCM) meridians. In this first part, the literature reviews on TCM and the AMI, as well as the functioning of the device, are reported. Specifically, medical and biophysical studies supporting the meridian theory are discussed, as well as biofield experiments performed with the AMI. The working of the AMI is explored, explaining in detail its parameters and their relation to the skin electrical activity. In the second part, previous reliability studies on acupoint electrodermal devices will be reviewed, supporting their use in biofield science, and comparing their characteristics and performance with those of the AMI. An original experiment will also be presented: The AMI was used on 100 healthy participants, to evaluate whether it could provide meaningful assessments of their biofield and subtle energy anatomy, in accordance with TCM principles. Results were positive, confirming the usefulness and reliability of the AMI for biofield science.

The measurement variability and working of this device were investigated, evaluating its capacity to assess human bioenergetics and Chi energy activity throughout the body meridians. The experiment involved 100 healthy participants, who were measured 5 times in the same psychophysical condition: In the analysis, it was determined whether the AMI could provide informative, meaningful, and repeatable assessments of the participants’ biofield and subtle energy anatomy, in accordance with TCM principles. Results showed that the AMI parameters return accurate and valuable information about the human bioenergetic system and psychophysical status. Among the results, it was found that the Chi energy relationships between Yin and Yang meridians are consistent with those predicted by TCM, thus validating this millenary philosophy and practice. This trend is best reflected in the acupoint Before-Polarization (BP) current, compared to other electrodermal parameters, revealing its importance for subtle energy research. Considering their reliability, scientific investigations and clinical applications with acupoint electrodermal devices are encouraged.
Bør krigen i Ukraina påvirke vårt syn på atomvåpen?
Authors: Fjærtoft Torgeir E.
Published: January 2025

Fire måneder før Russlands angrep på Ukraina, 15. november 2021, publiserte Internasjonal Politikk min artikkel «Norsk støtte til FNs totalforbud mot atomvåpen?». Jeg begrunnet hvorfor Norge burde slutte seg til FNs atomvåpenforbud, og sammen med Sverige ta initiativ til en europeisk politisk dialog med Russland uavhengig av USA. Denne nye artikkelen drøfter om krigen i Ukraina endrer de opprinnelige konklusjonene. Atomvåpenavskrekking virker i Ukraina ved å begrense krigens omfang på begge sider, men nettopp det øker samtidig risiko. For Norge medfører USAs nye baser risiko i en konfrontasjon mellom USA og Russland. Norge må gå sammen med andre europeiske land i et felles europeisk forsvar uten atomvåpen. EU bør koordinere en selvstendig europeisk pilar i NATO innenfor etablerte prosedyrer for rådslagning. Europa må ha nødvendig kontakt med Russland som gjennom flere stadier av diplomati kan utvikle seg fra krisehåndtering til enighet om rustningskontroll og en ny politisk orden. For å håndtere en ny sikkerhetspolitisk situasjon må UD oppgradere sine analyser for å styrke aktørforståelse og samhandlingskompetanse. Interne prosedyrer bør tilstrebe standardene for kvalitetskontroll i ISO 9000.
Abstract in English:Should the War in Ukraine Affect our View of Nuclear Weapons?Four months before Russia’s attack on Ukraine, Internasjonal Politikk published my article “Norwegian Support of the UN Ban of Nuclear Weapons?” I argued that Norway should endorse the UN ban and, with Sweden, initiate a European political dialogue with Russia independent of the United States. This article will discuss whether the war in Ukraine alters the previous article’s conclusions. Nuclear deterrence works in Ukraine by confining the scale of war on both sides, but precisely that raises the concomitant risk. The new US bases in Norway entail risk in a confrontation between the US and Russia. Norway now needs to join other European states in a common defense without nuclear arms. The EU should coordinate an independent European pillar in NATO within established procedures for consultation. Europe needs a necessary contact with Russia that through successive stages of diplomacy may evolve from crisis management to agreement on arms control and a new political order. To cope with the new security agenda, the Norwegian Ministry of Foreign Affairs needs to upgrade analyses of actors and improve interaction skills. Internal procedures should apply the guidelines for quality control set out in the standard manual ISO 9000.

Introduction. The protection and repair of concrete structures are the challenges of high priority, some solutions of which are presented in standards such as EN 1504 and GOST 32016–2012. Application of waterproof compounds is one of the main methods to protect concrete structures from water impact. Sealants are widely used to preserve the concrete properties, providing surface or volumetric hydrophobization. Purpose of the study was to develop and substantiate a new method to improve the efficiency of volumetric hydrophobization of protective layers made of dry mix mortar (DMM) based on microcement. Materials and Methods. Microcement MC MicroOST brand produced by New Technologies LLC was used as the main component of dry mixes, aluminous (AC-35-40) and high aluminous (HAC-70) cements were considered as aluminate components. Comparative assessment of hydrophobic properties of the prepared formulations of DMM based on microcement was carried out by contact angle and water absorption indicators. Results of the study showed that samples with introduction of aluminate component, such as high alumina cement (HAC), demonstrated high level of hydrophobicity and faster completion of water uptake into the material, relative to samples with HAC-35-40, samples of control formulation K-1, or with alternative additives (formulation with Mapelastic). It was found that introduction of high alumina cement in amount of 10–15 % provides maximum hydrophobicity for the proposed method. Analysis of the form of the water contact angle revealed formation of water-repellent film on the treated surface of samples with 10 and 15 % of high alumina cement. With regard to other coatings, it has been noted that they are highly resistant to water penetration deep into the material. These results demonstrate high efficiency of the proposed method to improve volumetric hydrophobization of protective layers

Published: January 2025

This research investigates the Evaluation of the Kotaku Program Policy in Preventing and Improving the Quality of Slum Settlements and Slum Housing in Central Pariaman District, Pariaman City. The research was motivated by the sub-optimal implementation of the Kotaku program and the condition of the drainage channels which were not maintained, as seen by the large amount of rubbish, water not flowing, and damaged channel stones. The research method uses a qualitative approach with descriptive methods and purposive sampling techniques.
      The results of the research show that the condition of the road, which was originally intended for pedestrians but is often used by motorbikes, has caused problems of damage and poor maintenance on the roads around the river. The drainage is also not well maintained, due to lack of supervision, and there is still a lot of rubbish in it, causing an unpleasant odor. The problem of full trash bins and lack of supervision from the Kotaku team illustrates the need to improve the effectiveness of this program. Better collaboration between the Kotaku team, local government and communities is needed to create a cleaner and healthier environment. Thus, improving infrastructure and stricter supervision are the keys to increasing the success of the Kotaku Program in improving the conditions of slum settlements and the surrounding environment.
DISKRESI DINAMIKA DAN PERUBAHAN KONSTITUSI MELALUI PUTUSAN-PUTUSAN MAHKAMAH KONSTITUSI DI INDONESIA
Authors: Rohida Leni
Published: January 2025

Penelitian ini membahas diskresi dinamika dan perubahan konstitusi di Indonesia melalui putusan-putusan Mahkamah Konstitusi (MK). Konstitusi merupakan hukum dasar yang menjadi landasan utama dalam penyelenggaraan negara, mengatur pembagian kekuasaan, serta menjamin hak dan kewajiban warga negara. Namun, seiring dengan perkembangan zaman, perubahan sosial, politik, dan ekonomi yang dinamis sering kali menimbulkan kebutuhan untuk melakukan penyesuaian terhadap aturan-aturan yang terkandung dalam konstitusi. Di Indonesia, Mahkamah Konstitusi (MK) memiliki peran sentral dalam proses penyesuaian ini melalui putusannya yang secara langsung maupun tidak langsung dapat mengubah tafsir konstitusi. Mahkamah Konstitusi memegang peran penting sebagai lembaga pengawal konstitusi yang berfungsi untuk menafsirkan, menguji, dan memutus sengketa yang terkait dengan konstitusi. Dalam menjalankan perannya, MK sering kali membuat putusan yang bukan hanya berfungsi untuk menegakkan hukum, tetapi juga mempengaruhi perubahan dan perkembangan hukum tata negara di Indonesia. Penelitian ini menggunakan metode yuridis normatif dengan mengkaji putusan-putusan Mahkamah Konstitusi yang dianggap signifikan dalam membawa perubahan terhadap konstitusi, baik dari segi interpretasi maupun aplikasinya. Beberapa putusan penting, seperti yang terkait dengan uji materi undang-undang, pembatasan kekuasaan eksekutif, dan perlindungan hak asasi manusia, dianalisis untuk mengidentifikasi pola perubahan yang terjadi dalam konstitusi. Hasil penelitian menunjukkan bahwa Mahkamah Konstitusi melalui putusannya sering melakukan reinterpretasi terhadap norma-norma konstitusional, yang pada akhirnya mengarah pada perubahan konstitusi secara substantif. Perubahan-perubahan ini umumnya terjadi melalui mekanisme penafsiran progresif terhadap ketentuan-ketentuan konstitusional yang ada, sehingga menghasilkan penyesuaian terhadap dinamika sosial, politik, dan ekonomi yang berkembang di masyarakat. Studi ini menyoroti bahwa diskresi MK dalam melakukan perubahan konstitusi tidak terlepas dari dinamika politik dan kepentingan publik yang mempengaruhi putusan-putusan tersebut.

Dalam penelitian ini, digunakan pendekatan Teori Pengembangan Pariwisata dengan Pendekatan Berbasis Kearifan Lokal menurut Sastrayuda dengan metode deskriptif kualitatif. Untuk memperoleh data, peneliti melakukan wawancara dan dokumentasi dengan teknik purposive sampling untuk memilih informan. Validitas data dipastikan melalui triangulasi sumber. Hasil penelitian menunjukkan bahwa pendekatan pengembangan pariwisata berbasis kearifan lokal menurut teori Sastrayuda dapat diterapkan pada pengembangan Pesta Hoyak Tabuik Berbasis Kearifan Lokal di Kota Pariaman. Dalam tahapan perencanaannya, terdapat musyawarah yang dilakukan antara Pemerintah Kota Pariaman dan para tokoh seperti Kerapatan Adat Nagari, niniak mamak, Bundo Kanduang, dan LKAAM. Sedangkan, komunitas sanggar dan tuo tabuik berperan langsung dalam pelaksanaannya. Pendekatan yang diterapkan memperhatikan potensi dan karakteristik produk budaya yang tersedia, yang tercermin dalam upacara tabuik yang dilaksanakan dengan nilai-nilai lokal yang terkandung di dalamnya. Namun, terdapat penurunan nilai kesakralan karena perayaan kini tidak lagi diadakan pada tanggal Muharam dan diubah mengikuti jadwal hari libur. Pendekatan pemberdayaan masyarakat tercermin melalui pemanfaatan sumber daya lokal untuk kerajinan dan produk olahan makanan, serta meningkatkan fasilitas pariwisata seperti penginapan yang memadai.
