Authors: Artiningrum Tati , Filiceldi Mahesa 
Published: May 2023

The Badaksinga Drinking Water Processing Installation is an installation owned by Perumda Tirtawening Drinking Water, Bandung City, has 2 of these installations, the first of which is a design from Degremont - France, built around 1954 with a capacity of 1000 liters/second. The second installation is an IWACO-Dutch design with a flow rate of 800 liters/second. The raw water for the two installations comes from the Cisangkuy River and the Cikapundung River. To purify the raw water, PAC (Poly Aluminum Chloride) is used as a coagulant which is a complex inorganic compound with a clear to yellowish color. The coagulant addition process must be carried out efficiently because this coagulation process is a chemical process that requires a large amount of money for the water treatment process apart from chlorination. Excessive addition of coagulant doses will cause the cost of using coagulant chemicals to swell so that it will have an impact on overall operational costs. The purpose of this study was to determine the effectiveness of using PAC in reducing turbidity, in the form of the optimum dose of coagulant, turbidity and pH. The method used is the Jar Test which is a tool to test the ability of coagulants to determine the optimum dose in a water treatment process. From the samples, the raw water turbidity varied from 17.1 to 281 NTU, fluctuating due to geographical location and environmental conditions around each and the degree of acidity or an average pH of 7.13. After the Jar Test was carried out, the optimum dose was produced at a coagulant concentration of 30 mg/l resulting in turbidity in the range of 1.1 to 5.0 NTU and an average turbidity reduction efficiency of 94.5%, the pH of raw water, after coagulation and flocculation with the Jar Test simulation tool, there was a decrease of 4.1% to an average of 6.99. This result is in accordance with Minister of Health Regulation No 492/MENKES/PER/10/2010 April 19 2020, namely turbidity of no more than 5 NTU and a pH of 6.5 – 8.5

Development is a process of change towards better conditions through planned efforts aimed at improving the welfare of the people by involving supporting elements, namely human resources, natural resources and technology. The three elements must synergize well so that inequality does not occur as a result of the development process both in terms of economic, social and environmental. The approach used in this study is a qualitative approach, with an exploratory method. Locke, Spriduso and Silferman put forward: ―qualitative research is interpretative research. As such, the biases, values and judgment of the researches become stated explicitly in the research report. Such openness is considered to be useful and positive. Based on the perspective of Meter and Horn theory (1975) which states that implementation will be the most successful where only small changes are needed and a consensus of high goals, broadly speaking, the implementation of GPP policy in South Kalimantan has not been optimal because the small changes needed have not been achieved, while the consensus goals have not been achieved properly

Published: May 2023

The purpose of this paper is to elaborate on the developmentof the qur'ān's pentak wilan transformation from a literal (textual) approach to a contextual approach by the hermeneutic method initiated by the contemporary Muslim intellectuals of Shaḥrūr. The idea of Shaḥrūr can beused as a method of interpreting the Qur'ān in this era of globalization so that Muslims can continue to adapt to the times. This paper is written using a library research model, because the objects of study are things related to various literature literature. This research uses a philosophical-hermeneutical method that is included in the qualitative approach, which intends to understand phenomena about the object of study, with the method of description in the form of words and language (narrative). Shaḥrūr introduced a linguistic approach called al-manhaj al-tarīkhī. Initially, he combined the linguistic methods of Abū 'Alī al-Fārisī, Ibn Jinnī, and 'Abd al-Qadīr al-Jurjāni. But eventually Shaḥrūr concluded the absence of synonyms in Arabic and Shaḥrūr also made Mu'jam Maqāyis al-Lughah by Ibn Fāris, one of the adherents of the absence of synonymity, his mandatory reference. It was this absence of synonymity that later became one of the principles of the Shaḥrūr method of interpretation. In addition to the synonmatic denial in the hermentic method Shaḥrūr is identical about the theory of hudud or limit.

Published: May 2023

Good quality planting materials for yam cultivation is a major challenge and adapting the most preferred local varieties to high ratio propagation methods such as the vine cutting could help ameliorate this constraint. An experiment was conducted in the screen house at CSIR-Savanna Agricultural Research Institute to assess the response of ‘Labako’, ‘Nyamenti’ and ‘Kpamyo’ (check) to vine cutting under different substrates. The experiment was 3 x 6 factorial arranged in a completely randomized design with 3 replications. Single node cuttings were obtained from 3 months old plants and established in the various rooting substrates (carbonized rice husk; fermented rice bran; aged rice husk; top-soil ,cocopeat and carbonized rice husk + top-soil; 2:1).Highly significant differences (P<0.001) existed in main effects and interaction of the factors. All cultivars attained 100% survival in CRH (carbonized rice husk) and cocopeat. Kpamyo and Nyamenti had 89.6% regeneration in cocopeat, FRB (fermented rice bran) and CRH. Labako exhibited the maximum shoot growth (31 cm) in CRH whiles the minimum (10 cm) was observed in ARH (aged rice husk) for Kpamyo. Six nodes were produced by Nyamenti in CRH, whiles Kpamyo produced 3 nodes in the same substrate. Labako initiated 88% tuberization, higher than Kpamyo with 75%. Generally, the cultivars were successfully adapted to the vine cutting technique in CRH, FRB as well as cocopeat. CRH and FRB are locally available, hence less expensive to acquire and therefore recommended for cost-effective single node propagation of the popular local yam cultivars.

AbstractBackground and PurposeAnatomic changes during head and neck radiotherapy can impact dose delivery, necessitate adaptive replanning, and indicate patient‐specific response to treatment. We have developed an automated system to track these changes through longitudinal MRI scans to aid identification and clinical intervention. The purpose of this article is to describe this tracking system and present results from an initial cohort of patients.Materials and MethodsThe Automated Watchdog in Adaptive Radiotherapy Environment (AWARE) was developed to process longitudinal MRI data for radiotherapy patients. AWARE automatically identifies and collects weekly scans, propagates radiotherapy planning structures, computes structure changes over time, and reports important trends to the clinical team. AWARE also incorporates manual structure review and revision from clinical experts and dynamically updates tracking statistics when necessary. AWARE was applied to patients receiving weekly T2‐weighted MRI scans during head and neck radiotherapy. Changes in nodal gross tumor volume (GTV) and parotid gland delineations were tracked over time to assess changes during treatment and identify early indicators of treatment response.ResultsN = 91 patients were tracked and analyzed in this study. Nodal GTVs and parotids both shrunk considerably throughout treatment (−9.7 ± 7.7% and −3.7 ± 3.3% per week, respectively). Ipsilateral parotids shrunk significantly faster than contralateral (−4.3 ± 3.1% vs. −2.9 ± 3.3% per week, p = 0.005) and increased in distance from GTVs over time (+2.7 ± 7.2% per week, p < 1 × 10−5). Automatic structure propagations agreed well with manual revisions (Dice = 0.88 ± 0.09 for parotids and 0.80 ± 0.15 for GTVs), but for GTVs the agreement degraded 4–5 weeks after the start of treatment. Changes in GTV volume observed by AWARE as early as one week into treatment were predictive of large changes later in the course (AUC = 0.79).ConclusionAWARE automatically identified longitudinal changes in GTV and parotid volumes during radiotherapy. Results suggest that this system may be useful for identifying rapidly responding patients as early as one week into treatment.

Published: May 2023

AbstractStructure engineering has proven to be an effective strategy for improving the catalytic performance and reducing the cost of ruthenium oxide‐based catalysts toward oxygen evolution reactions (OER). Herein, a polyhedron‐shaped yolk‐shell structure composed of zinc‐cobalt‐ruthenium ternary metal alloy oxide (ZnCo‐RuO2/C) is prepared, by taking advantage of the Kirkendall effect. The yolk‐shell frame and the ensembled metal oxide nanoparticles are 116.9 ± 25.9 nm and 3.1 ± 0.7 nm in diameter, respectively. The porous yolk‐shell structure of ZnCo‐RuO2/C exposes abundant active sites and facilitates mass transfer for OER. Theoretical calculations indicate that ZnCo‐RuO2 may break the linear scaling relationship for the OER intermediates and dramatically reduces the energy barrier of the potential determining step, which may be one of the factors that are responsible for the enhanced OER performance of ZnCo‐RuO2/C. In 1 m KOH aqueous electrolyte, ZnCo‐RuO2/C delivers an overpotential of only 180 mV at 10 mA cm−2 and a Tafel slope of 63 mV dec−1, superior to that of single metal‐doped, pristine and commercial RuO2. As an anode catalyst of zinc‐air batteries, ZnCo‐RuO2/C exhibits improved power density and durability relative to commercial RuO2, very promising for practical application.
High‐Throughput Screening of Heterogeneous Transition Metal Dual‐Atom Catalysts by Synergistic Effect for Nitrate Reduction to Ammonia

Published: May 2023

AbstractNitrate reduction to ammonia has attracted much attention for nitrate (NO3‐) removal and ammonia (NH3) production. Identifying promising catalyst for active nitrate electroreduction reaction (NO3RR) is critical to realize efficient upscaling synthesis of NH3 under low‐temperature condition. For this purpose, by means of spin‐polarized first‐principles calculations, the NO3RR performance on a series of graphitic carbon nitride (g‐CN) supported double‐atom catalysts (denoted as M1M2@g‐CN) are systematically investigated. The synergistic effect of heterogeneous dual‐metal sites can bring out tunable activity and selectivity for NO3RR. Amongst 21 candidates examined, FeMo@g‐CN and CrMo@g‐CN possess a high performance with low limiting potentials of ‐0.34 and ‐0.39 V, respectively. The activities can be attributed to a synergistic effect of the M1M2 dimer d orbitals coupling with the anti‐bonding orbital of NO3‐. The dissociation of deposited FeMo and CrMo dimers into two separated monomers is proved to be difficult, ensuring the kinetic stability of M1M2@g‐CN. Furthermore, the dual‐metal decorated on g‐CN significantly reduces the bandgap of g‐CN and broadens the adsorption window of visible light, implying its great promise for photocatalysis. This work opens a new avenue for future theoretical and experimental design related to NO3RR photo‐/electrocatalysts.
Biomass‐Derived Inks with Tailored Pteridine Derivatives for Sustainable Printed Micro‐Supercapacitors

Published: May 2023

AbstractUsing biological redox compounds holds great potential in designing sustainable energy storage systems, but it is essential for structure optimization of biological redox centers and in‐depth studies regarding their underlying energy storage mechanisms. Herein, a molecular simplification strategy is proposed to tailor the redox unit of pteridine derivatives, an essential component of ubiquitous electron transfer proteins in nature. The tailored pteridine derivatives can be combined with biomass holey graphene (BHG) to fabricate an ink with a micrometer‐scale resolution for printing flexible electrodes for micro‐supercapacitor (MSCs). The reversible tautomerism of pteridine derivatives from alloxazinic to isoalloxazinic structure is first unveiled in supercapacitors. Through molecular tailoring, printed MSC electrodes using pteridine derivatives/BHG ink demonstrate excellent charge storage, outstanding areal capacitance (95.3 mF cm−2 at 0.1 mA cm−2), energy density (16.3 µWh cm−2), power density (208 µW cm−2), long‐term cycling performance (90.5% retention after 10 000 cycles), easy integration, and exceptional flexibility (maintaining capacitance at various bending states). The non‐covalent interaction of tailored pteridine molecules with redox centers and biomass porous graphene suggests a mature screen‐printing technology for fabricating a sustainable energy storage system with a rational MSC configuration.
