Dyes are the most widely employed materials for coloring applications, especially for industrial purposes; thus, dyes are applied in the textile, cosmetics and foodstuffs. Dyes are very important owing to their applications in all aspects of human life. Accordingly, the production volume of dyes around the world is increasing. In this study, a new type of multifunctional material: polyaniline/Nb2O5/MnO2 and polyaniline/Nb2O5/Cr2O3 nanocomposites, was prepared by chemical polymerization from aniline monomer in the presence of metal oxides (Nb2O5, Cr2O3, and MnO2) and an oxidant (ammonium persulfate) in acidic aqueous solution for the elimination of dye from water. Herein, the nanocomposite was found to be a favorable adsorbent for wastewater treatment due to its high adsorption and efficiency, self-regeneration quality, low cost and easy synthesis. Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy and UV-visible spectroscopy were used to assess the synthesized nanocomposites' characteristics. From the results, we discovered that polyaniline nanocomposites doped with Nb2O5 and MnO2 nanoparticles had a higher adsorption efficiency (~97.37%) than those found in polyaniline with Cr2O3 and MnO2 (~94.3%). We looked at the adsorption conditions, including the medium's pH, the initial dye concentration, the dosage of the adsorbent, and the adsorption time.

The sparse treatment of highly toxic leachates produced in landfills due to the excessive generation of urban solid waste is a common problem worldwide. For this reason, this research aims to show the convenience of the use of algal biotechnology in leachate bioremediation processes. Nannochloris sp. species was used in this research. It was isolated and cultured for bioassays. The leachate was diluted to 5 and 10% in the microalgae cultures during a period of 8 d in which the growth of the species. Then removal of nutrients (phosphate and nitrate) and the production of lipids by the microalgae were measured. Nannochloris sp. removed more than 70% of the phosphates and 60% of the nitrates from samples. This result shows the benefits of using these microalgae to treat landfill leachate at low cost and also with the potential to obtain bio-lipids that may be useful for biodiesel production.

Published: October 2023

Biodiesel production from non-edible oil is an alternative way to reduce edible oil dependency and reduce the competition for feed and food. Candlenut oil (Aleurites moluccana L.) is one of the non-edible oils which can be used as feedstock for biodiesel production since they have a high oil content. Herein, the biodiesel production from candlenut oil has been conducted using zinc oxide (ZnO) synthesized by the polyol method. Polyol methods facilitated the formation of ZnO nanoparticles with various shapes, including spherical, rod, and hexagonal. Besides, ZnO showed a mesoporous characteristic, facilitating the conversion of fat fatty acid to fatty acid methyl ester (FAME) of 61%. Increasing ZnO dosage led to enhancing the FAME yield. Similarly, the FAME yield was also improved by increasing the reaction time. The results of esterification of candlenut oil and methanol yielded 70.76% FAME with 2% nano-ZnO polyol catalyst at 180 min reaction time at room temperature whilst being stirred constantly at 400 rpm. A good FAME conversion using ZnO at room temperature provides good information to produce biodiesel with a simple method. Apart from that, photocatalytic promoted transesterification at room temperature, which is beneficial for reducing energy consumption.

Authors: Saadi Lina , Adnan Shaimaa
Published: October 2023

In this research, the synthesis of new substituted oxazolone derivatives is described via Erlenmeyer synthesis of N-acyl amino acid. Firstly, the azo derivative 1 was prepared by coupling the diazonium salt of 3-amino-4-methoxybenzoic acid with 4,5-dichloroimidazole in sodium hydroxide solution. Benzoyl chloride derivative 2, the key intermediate of the synthesis, was synthesized by the acylation of azo-carboxylic acid derivative 1 with thionyl chloride. The resulting acyl chloride derivative reacted with glycine in a basic catalyst to form a hippuric acid derivative 3. After that, oxazolone derivatives 4a–4f were prepared via the reaction of the hippuric acid derivative with various aromatic aldehydes. All new compound structures were confirmed by spectral techniques, i.e., FTIR, 1H-NMR, 13C-NMR spectroscopy, and elemental analysis. The antimicrobial activity (Staphylococcus aureus and Escherichia coli) of all new compounds was screened in vitro. The results against S. aureus and E. coli showed that most of the tested compounds have an activity ranging from moderate to low. The antioxidant activity of derivative 4a was also evaluated and showed good antioxidant activity.

Published: October 2023

Three complexes ([CuL2(H2O)2], [NiL2(H2O)2], and [ZnL2Cl2]) have been synthesized through the reaction of metal salts and levofloxacin and characterized by spectrophotometers. The morphology of the complexes was investigated using field emission scanning electron microscopy (FESEM). The physicochemical properties of these complexes were evaluated using the Brunauer-Emmett-Teller (BET) and Barrett-Joyner-Halenda (BJH) techniques. Furthermore, the storage capacity of these complexes was verified using the H-sorb 2600 analyzer at a temperature of 323 K and varying pressure conditions. The obtained data substantiates that the synthesized complexes exhibit favorable attributes for CO2 absorption. The surface area reaches 24.97 m2/g with capacities of 123.073 m3/g and 34.400 m3/g to adsorb CO2. The escalating levels of CO2 in the atmosphere, primarily resulting from the combustion of fossil fuels to meet the surging energy requirements, pose a pressing environmental challenge. Consequently, there has been a surge in research focused on the development of novel materials aimed at facilitating CO2 storage.

Published: October 2023

Background: The Coronavirus Disease 2019 (COVID-19) pandemic has an impact on the physical and mental health of individuals and all of society. During the COVID pandemic, all social and physical activities of each individual are limited. Physical-social distancing or physical restrictions have an impact on mental health and psychological problems. This anxiety is also experienced by medical students as Co-Assistants (young doctors) during their education in hospitals. Objectives: This study aimed to discuss matters related to the impact of the COVID-19 on medical students’ mental health during the pandemic. Method: This cross-sectional study used the Self-Reporting Questionnaire-20. Mental health problems of college students during the pandemic were assessed and analyzed for their level of anxiety. This study involved 69 medical students as Co-Assistants (young doctors) in the professional study program using purposive sampling technique. Results: The results of the study found that among Co-Assistants who underwent clinical clerkship during the COVID-19 pandemic as much as 44.9% experienced mental health disorders. We also found that the female Co-Assistants were twice as likely to experience mental health problems as male Co-Assistants. The most common type of mental health problem was experiencing symptoms of depression. Conclusion: During the two years of the pandemic, while living the ‘new normal’, Co-Assistants felt the fear of being infected with the lack of personal protective equipment, economic problems for their parents, and facing the challenges of distance education. In comparing the mental health problems of the Co-Assistants, the most common during the COVID-19 pandemic were the symptoms of depression.
What Kind of Medical Specialist Can Support Primary Health Transformation in Indonesia?
Authors: Vidiawati Dhanasari
Published: October 2023

The transformation of basic health services that was proclaimed as part of the transformation of health services by the Minister of Health of the Republic of Indonesia in 2022 is a dream come true for me. Even though the World Health Organization (WHO) has been advocating for it since 2008 in its report Primary Care Now More Than Ever, Indonesia finally made it happen when the Ministry of Health was not led by a doctor. The emphasis on 'not working as a doctor' as the leader of the Ministry of Health seems to be 'beneficial' for primary health services in Indonesia, which so far has been under the shadow of the 'non-specialist and specialist' bureaucratic level of management which is equated with 'primary services and non-primary services'. So far, the terms and understanding of the government, BPJS, and doctors regarding medical specialist are essentially referral services, not primary services. It is as if a doctor working in primary care is considered not an expert. But if they become an expert, then they should be transferred to another place of work.

Appropriation and Sexual Obligation: A Feminist Reading of Khushwant Singh’s The Company of Women
Authors: Marwaha Priyanka , Nancy Dr
Published: October 2023

The patriarchal perspective has continually made women a puppet in a man's hands. The male society assigns women a secondary position in the household. So, man becomes the principal governing factor that appropriates and subjugates women. This paper critically analyses how the men appropriate and sexually obligate women in one way or the other in Khushwant Singh's The Company of Women. Published in 1999, it is Khushwant Singh's fourth novel. It presents the episodes of appropriation and sexual obligation of women- ranging from an Afro-American teenager to a Bai in Bombay by the narrator. The concept of Appropriation of Women by Collette Guillaumin has been applied as a theoretical framework. After a thorough reading of the selected text, relevant sentences and passages have been cited as textual evidence. The research findings indicate that the text understudy affirms the appropriation and sexual obligation of women.

Fermion-qudit quantum processors for simulating lattice gauge theories with matter
Authors: Zache Torsten V. , González-Cuadra Daniel , Zoller Peter
Published: October 2023

Simulating the real-time dynamics of lattice gauge theories, underlying the Standard Model of particle physics, is a notoriously difficult problem where quantum simulators can provide a practical advantage over classical approaches. In this work, we present a complete Rydberg-based architecture, co-designed to digitally simulate the dynamics of general gauge theories coupled to matter fields in a hardware-efficient manner. Ref. \cite{Gonzalez_2022} showed how a qudit processor, where non-abelian gauge fields are locally encoded and time-evolved, considerably reduces the required simulation resources compared to standard qubit-based quantum computers. Here we integrate the latter with a recently introduced fermionic quantum processor \cite{Gonzalez_2023}, where fermionic statistics are accounted for at the hardware level, allowing us to construct quantum circuits that preserve the locality of the gauge-matter interactions. We exemplify the flexibility of such a fermion-qudit processor by focusing on two paradigmatic high-energy phenomena. First, we present a resource-efficient protocol to simulate the Abelian-Higgs model, where the dynamics of confinement and string breaking can be investigated. Then, we show how to prepare hadrons made up of fermionic matter constituents bound by non-abelian gauge fields, and show how to extract the corresponding hadronic tensor. In both cases, we estimate the required resources, showing how quantum devices can be used to calculate experimentally-relevant quantities in particle physics.
On the role of entanglement in qudit-based circuit compression
Authors: Gao Xiaoqin , Appel Paul , Friis Nicolai , Ringbauer Martin , Huber Marcus
Published: October 2023

Gate-based universal quantum computation is formulated in terms of two types of operations: local single-qubit gates, which are typically easily implementable, and two-qubit entangling gates, whose faithful implementation remains one of the major experimental challenges since it requires controlled interactions between individual systems. To make the most of quantum hardware it is crucial to process information in the most efficient way. One promising avenue is to use higher-dimensional systems, qudits, as the fundamental units of quantum information, in order to replace a fraction of the qubit-entangling gates with qudit-local gates. Here, we show how the complexity of multi-qubit circuits can be lowered significantly by employing qudit encodings, which we quantify by considering exemplary circuits with exactly known (multi-qubit) gate complexity. We discuss general principles for circuit compression, derive upper and lower bounds on the achievable advantage, and highlight the key role played by entanglement and the available gate set. Explicit experimental schemes for photonic as well as for trapped-ion implementations are provided and demonstrate a significant expected gain in circuit performance for both platforms.

Published: October 2023

Hakim Mahkamah Syar’iyah memiliki peranan strategis dalam upaya pencegahan perkawinan anak, karena setiap orangtua yang ingin menikahkan anak di bawah umur harus mendapatkan dispensasi perkawinan dari Mahkamah Syar’iyah. Kajian ini berusaha untuk menganalisis peran dan tantangan yang dihadapi hakim dalam mencegah perkawinan usia anak di Mahkamah Syar’iyah serta pertimbangan dalam menerima maupun menolak dispensasi kawin. Jenis penelitian yang digunakan yuridis empiris dengan tujuan mendeskripsikan peranan hakim mencegah perkawinan anak. Sumber data primer diperoleh melalu wawancara langsung dengan hakim. Data sekunder terdiri dari bahan hukum primer dan bahan hukum sekunder. Hasil penelitian menunjukkan bahwa hakim memiliki peranan strategis dalam upaya mencegah praktik perkawinan usia anak, hal ini disebabkan setiap perkawinan anak harus memperoleh izin Mahkamah Syar’iyah. Wujud peranan hakim dikonkritkan dengan mendorong orangtua tidak melanjutkan permohonan dispensasi kawin dengan memberikan nasehat-nasehat serta dampak yang muncul pasca perkawinan baik psikologis, mental maupun pendidikan anak. Tantangan yang dihadapi hakim dalam mengadili perkara dispensasi adalah pemahaman masyarakat terhadap bahaya perkawinan anak belum tersosialisasikan dengan baik dan harus menghadirkan saksi yang memadai agar latar belakang keinginan menikah dapat didalami secara komprehensif. Pertimbangan hakim mengabulkan permohonan dispensasi dengan mempertimbangkan aspek kepentingan terbaik bagi anak (the best interest of the child) dan adanya bukti yang menunjukkan bahwa pernikahan suatu hal yang mendesak dilakukan berdasarkan fakta di persidangan.
Status Istri Mafqud dalam Pandangan Imam Syafi’i Dan Ibnu Qudamah (Studi Komparatif Pendapat Imam Syafi’I dan Ibnu Qudamah)
Authors: Hafifi Ikmal
Published: October 2023

Penelitian ini bertolak dari pemikiran bahwa permasalahan status hukum isteri yang kehilangan suaminya merupakan permasalahan yang tidak diungkapkan dalam al-Quran secara jelas. Untuk itu dalam menyelesaikan masalah ini harus menggali pendapat dari para mujtahid. Imam Syafi’i dan Ibnu Qudamah merupakan mujtahid yang berbeda generasi yang memilki metode ijtihad tersendiri dalam menetapkan sebuah hukum dalam hal ini status hukum isteri yang kehilangan suaminya. Hasil analisis menunjukkan bahwa Imam Syafi’i menggunakan hadits dari Ali ra. sebagai dasar hukum. Sedangkan Ibnu Qudamah menggunakan fatwa sahabat sebagai dasar hukum yaitu pendapat Umar ra. Mengenai isteri yang kehilangan suaminya. Metode istinbath yang digunakan oleh Imam Syafi’i adalah dengan menggunakan pendekatan dalalat nash mantuq ghair sharih dan hadits dari Ali ra. Sedangkan Ibnu Qudamah menggunakan fatwa sahabat Umar ra. Perbedaan tersebut disebabkan karena perbedaan kedua Imam tersebut dalam menggunakan dalil-dalil hukum. Dengan demikian dapat disimpulkan bahwa perbedaan pendapat dan perbedaan dalam penggunaan dalil dalam metode istinbath merupakan faktor yang berpengaruh terhadap perbedaan pendapat Imam Syafi’i dan Ibnu Qudamah dalam menetapkan status hukum isteri karena suami yang hilang.

Otoritas Hukum Sunah sebagai Wahyu
Authors: Abubakar Ali
Published: October 2023

Di antara sebab perbedaan pendapat ulama dalam masalah hukum adalah penempatan posisi sunah Nabi: setingkat dengan al-Qur'an atau berada di bawahnya. Hal ini diperkuat oleh wacana bahwa sunah adalah bagian dari wahyu melalui teori ḥikmah yang dikemukakan oleh para ulama fikih.  Konsekuensi dari teori ḥikmah ini, ketentuan yang dimuat di dalam sunah memiliki otoritas setingkat dengan al-Qur'an. Kata “ḥikmah” sendiri memang disebutkan beberapa kali di dalam al-Qur'an dan menjadi argumentasi utama para ulama.  Penelusuran terhadap penggunaan kata tersebut dalam al-Qur'an menunjukkan bahwa kata ḥikmah memiliki banyak arti; al-Qur'an menggunakannya tidak hanya seputar Nabi Muhammad, tetapi juga di lingkungan Nabi lain dan manusia biasa. Karena itu, mewacanakan sunah sebagai bagian dari wahyu dengan teori ḥikmah memiliki kelemahan. Selain itu, praktik para Sahabat yang memisahkan berbagai peran Muhammad: Nabi, pemimpin/kepala negara, dan manusia biasa menunjukkan bahwa ḥikmah yang otoritasnya setingkat dengan wahyu hanya dalam masalah tasyrī’ (hukum). Hal ini dikuatkan oleh unsur kemanusiaan Muhammad yang disebut dengan jelas dalam al-Qur'an.
Analisis Yuridis Terhadap Pembagian Harta Warisan Ahli Waris Pengganti Pada Putusan Mahkamah Syar’iyah No 245/Pdt.G/2017/MS.Bna.

Published: October 2023

Pembaruan hukum kewarisan Islam di Indonesia dalam Kompilasi Hukum Islam (KHI) berupa pemberian hak seorang ahli waris yang telah meninggal dunia kepada keturunannya yang masih hidup. Aturan ini tercantum dalam Pasal 185 KHI, berdasarkan sebuah Putusan No 245/Pdt.G/2017/MS.Bna hakim mempersamakan bagian harta warisan yang diterima oleh ahli waris pengganti yaitu 3/33 (tiga pertiga puluh tiga) sedangkan ahli waris pengganti dalam putusan tersebut ada dua macam, pertama menggantikan kedudukan ayah dan ada menggantikan ibunya. Ahli waris pengganti seharusnya mendapatkan bagian harta warisan sesuai dengan ahli waris yang digantikan, kalau ahli waris pengganti menggantikan kedudukan ayahnya maka dia memperoleh harta warisan sesuai yang didapatkan ayahnya dan sebaliknya maka dia mendapatkan bagian harta warisan sesuai dengan bagian ibunya. Pertimbangan hakim dalam memberikan bagian warisan terhadap ahli waris pengganti dalam putusan No 245/Pdt.G/2017/MS.Bna dan tinjauan hukum Islam terhadap bagian harta warisan yang didapatkan oleh ahli waris pengganti dalam putusan No 245/Pdt.G/2017/MS.Bna adalah putusan majelis hakim memberikan hak sama atas ahli waris pengganti dengan dasar hukum Pasal 185 KHI Ayat (2) dengan dasar pertimbangan ahli waris pengganti tidak boleh mendapatkan warisan melebihi bagian anak perempuan pewaris dan bagian yang paling sedikit yaitu anak perempuan pewaris. Putusan hakim tentang pemberian warisan terhadap ahli waris pengganti laki-laki dan perempuan sama rata tidak sesuai dengan dengan Pasal 176 KHI dan alquran surat An-nisa’ ayat 11 yaitu dua berbanding satu. Menurut tinjauan hukum Islam dalam ketetapan yang disepakati oleh ulama melalui ijtihad surat an-nisa’ ayat 11 tidak semua cucu bisa jadi ahli waris. Cucu yang menjadi ahli waris itu hanyalah cucu laki-laki atau juga cucu perempuan dari anak laki-laki. Sedangkan cucu perempuan dari anak perempuan, bukanlah ahli waris.

Permasalahan yang sering terjadi dalam kehidupan rumah tangga yang dapat memicu terjadinya perceraian salah satunya adalah kasus nusyuz. Namun sering terjadi di kalangan masyarakat yaitu nusyuz suami yang merupakan suami yang meninggalkan tanggung jawabnya kepada keluarga, sebagaimana telah tersirat di dalam Q.S An-Nisa’ ayat 128. Dalam tulisan ini peneliti mengkaji tentang peran tokoh masyarakat dalam penyelesaian kasus nusyuz suami di Gampong Jeulingke. Permasalahan yang diangkat dalam skripsi ini ada tiga: pertama, apakah faktor-faktor terjadinya kasus nusyuz suami di Gampong Jeulingke? Kedua, bagaimana peran tokoh masyarakat Gampong Jeulingke dalam menyelesaikan kasus nusyuz suami? Ketiga, bagaimana perspektif hukum Islam dalam menyelesaikan kasus  nusyuz suami di Gampong Jeulingke? Metode yang digunakan peneliti adalah penelitian lapangan (field research). Penelitian ini bersifat kualitatif. Hasil penelitian ditemukan bahwa penyebab terjadinya nusyuz suami ada empat yaitu faktor selingkuh, faktor emosi, faktor ekonomi dan suami yang tidak tertarik lagi pada istri. Peran yang dilakukan oleh Gampong Jeulingke untuk penyelesaian kasus nusyus suami dengan menjadi hakam (juru damai) yaitu Tgk. Imam Gampong, Tuha Peut, Kepala Lorong dan tokoh masyatakat lainnya dengan cara menasihati, perdamaian atau mediasi apabila tidak dapat mencapai keputusan maka diselesaikan di pengadilan. Menurut perspektif hukum Islam penyelesaian kasus nusyuz suami yang dilakukan oleh Gampong Jeulingke sudah sesuai dengan hukum Islam berdasarkan Q.S Al-Imran ayat 104 dan Q.S At-Tahrim ayat 6.

Telah dilakukan penelitian dengan menggunakan metode geolistrik konfigurasi Schlumberger yang bertujuan untuk mengetahui keberadaan akuifer baik dari segi kedalaman maupun ketebalan akuifer di Desa Jati Mulyo Kecamatan Dendang Kabupaten Tanjung Jabung Timur, Provinsi Jambi. Pengukuran di lapangan sebanyak 15 titik sounding dengan masing-masing panjang lintasan 400 m, diperoleh jenis batuan dan nilai resistivitas dari hasil pengolahan melalui software IPI2Win sebagai berikut, yaitu top soil dengan nilai resistivitas 20 Ωm sampai 200 Ωm, lempung dengan nilai resistivitas berkisar antara 1 Ωm sampai 15 Ωm, kemudian lempung pasiran yang memiliki nilai resistivitas berkisar antara 15 Ωm sampai 29 Ωm, selanjutnya untuk pasir dengan nilai resistivitas berkisar antara 29 Ωm sampai 100 Ωm, dan kerikil dengan nilai resistivitas besar dari 100 Ωm. Lapisan pasir dan kerikil disini diduga sebagai lapisan yang membawa air (akuifer) secara baik, dikarenakan memiliki nilai porositas dan permeabilitas yang cukup tinggi. Berdasarkan hasil pemodelan 2D yang telah diolah menggunakan software RockWork 15, lapisan yang berpotensi sebagai akuifer berada pada kedalaman 20 m sampai 50 m. Dimana pola akuifer semakin mendalam dan menebal kearah timur laut. Selain itu akuifer juga berada pada kedalaman 75 m sampai 100 m di Barat Daya pemukiman Desa Jati Mulyo. Sehingga untuk ketebalan akuifer di Desa Jati Mulyo berkisar antara 25 m sampai 30 m.

Sungai Batang Hari merupakan sungai terpanjang di pulau Sumatera yang mengalir melewati Provinsi Sumatera Barat dan Provinsi Jambi. Sepanjang Daerah Aliran Sungai (DAS) Batang Hari masih ditemukan lokasi aktivitas Penambangan Emas Tanpa Izin (PETI) yang beroperasi. Sumber air yang berasal dari sungai maupun bawah tanah di daerah penambangan emas dapat terkontaminasi radionuklida alam seperti Uranium-238 (238U), Torium-232 (232Th), Radium-226 (226Ra), Polonium-210 (210Po), Kalium (40K), dan Timbel-210 (210Pb). Pentingnya untuk menilai kualitas air yang dikonsumsi dari aspek radioaktif, maka perlu dilakukan penelitian pengukuran radionuklida 238U, 232Th, dan 40K pada air sungai, air sumur (bawah tanah), dan air minum dari daerah sampel yang dialiri oleh sungai Batang Hari yaitu Kota Jambi, Kab. Muaro Jambi, Kab. Tebo, Kab. Batanghar, dan  Kab. Bungo. Sampel diukur menggunakan spektrometer gamma detektor High Purity Germanium (HPGe). Hasil penelitian menunjukkan konsentrasi aktivitas tertinggi 238U, 232Th, dan 40K  masing- masing yaitu 0,1916± 0,05 Bq.L-1; 0,04±0,03 Bq.L-1; dan 0,68±0,04 Bq.L-1. Konsentrasi aktivitas pada sampel air berada di bawah batas ambang yang direkomendasikan oleh PERKA BAPETEN No. 9 Tahun 2009, WHO Guidelines for Water Quality 2011, dan UNSCEAR Report 2000 sehingga aman dan memenuhi syarat standar kualitas radioaktif air.

The educational process, which is supported by adequate laboratory facilities and infrastructure, will produce professional higher education tri-dharma outputs, both for students and lecturers. The Medical Equipment Laboratory is a place where experimental studies with various equipment and devices, analyses, and observations are carried out. The amount of electrical energy used by a university can be measured using an electric energy meter, namely the kWh meter, but the university cannot monitor which building or room uses the most electrical energy because it only knows the amount of power used each month. Given these problems, a digital kWh Meter monitoring tool based on the Internet of Things (IoT) is designed to measure the amount of current, voltage, power, and costs that must be incurred while using medical equipment and can then be monitored in real time using the Blynk application as the server. The implementation system for monitoring the kwh meter using the PZEM-004T sensor has a very good accuracy rate of 99.52% for measuring voltage and 99.87% for measuring current on medical equipment in the medical equipment laboratory at the PGRI Yogyakarta University. It was found that the greater the applied load value, the more the impact on data outputs such as current and voltage would affect the size of the monthly electricity bill. The monitoring system can be carried out within a radius of 20 meters as long as the smartphone is connected to a WiFi connection. Monitoring activities and electrical device control activities can be carried out.

Sebaran lindi dapat menyebabkan pencemaran pada air tanah di sekitar Tempat Pembuangan Akhir (TPA). Penelitian ini bertujuan untuk memetakan sebaran lindi di sekitar TPA Batu Layang. Identifikasi sebaran lindi dilakukan berdasarkan sebaran nilai self-potential di permukaan. Pengukuran dilakukan menggunakan metode self potential (SP) dengan konfigurasi fixed base. Konfigurasi ini menggunakan 2 buah elektroda, 1 buah elektroda berada di titik referensi (base) dan elektroda lainnya berpindah-pindah di sepanjang lintasan (rover) untuk mengukur nilai self-potensial di titik pengukuran. Pengukuran di  lapangan mengaplikasikan 4 lintasan dengan panjang masing-masing 110 m, jarak antar lintasan sebesar 5 m, dan jarak elektroda (porous pot) sebesar 5 m. Hasil penelitian menunjukkan bahwa nilai self-potential yang diperoleh sebesar 7,62 mV hingga -12,38 mV. Akumulasi aliran lindi diinterpretasi memiliki nilai self-potensial yang relatif lebih rendah dengan nilai anomali -8 mV hingga -14 mV. Nilai potensial tinggi terdapat di bagian selatan, sedangkan  nilai potensial rendah terdapat di bagian utara lokasi penelitian. Dengan demikian, aliran lindi diduga terakumulasi pada arah barat yang berdekatan dengan tumpukan sampah TPA Batu Layang.
Global Value Chain Participation and Labour Productivity among Manufacturing Firms in Vietnam

Published: October 2023

This study assesses the state of global value chain (GVC) participation by manufacturing firms in Vietnam and examines the impact of GVC participation on labour productivity. Utilising firm-level data from the Vietnam Technology and Competitiveness Survey and Vietnam Enterprise Survey from 2009 to 2018, we employ panel fixed-effect regression to analyse the dynamics. The findings show that Vietnam’s GVC participation has been driven mainly by backward rather than forward linkages, signifying a reliance on foreign inputs for exports. The study found a positive impact of backward and forward GVC participation on labour productivity. However, the results show a stark contrast when considering the degree of GVC participation (i.e. GVC participation index). While forward GVC participation positively impacts labour productivity, backward GVC participation demonstrates a negative effect. The results partly reject the learning-to-learn hypothesis while supporting the notion that productivity improvements in Vietnam are associated with learning-by-exporting and learning-by-supplying. We suggest that the prioritisation of forward GVC participation should be accompanied by well-designed backward participation strategies to promote labour productivity. The study concludes with a few policy implications.
