Published: January 2024

Di provinsi Sumatera Selatan dengan luas 91.592 km² memiliki banyak jenis tanah bermasalah salah satunya jenis tanah lempung lunak, tanah ini dikatakan tanah bermasalah karena memiliki kandungan air yang tinggi pada saat hujan menyebabkan nilai kuat geser tanah menjadi kecil dan daya dukung tanah menjadi rendah sehingga tidak dapat dilakukannya pembangunan konstruksi diatasnya maka perlu dilakukan upaya untuk meningkatkan daya dukung tanah tersebut, salah satunya dilakukan stabilisasi tanah. Penelitian ini bertujuan umtuk mengetahui bagaimana pengaruh penambahan semen portland dengan variasi 4%, 7% dan 10% terhadap kuat geser tanah pada stabilisasi tanah lempung lunak dengan mengambil sampel tanah yang berlokasi pada jalan R. Dentjik Aasari. Terdapat tiga jenis pengujian yang dilakukan yakni pengujian properties untuk mengklasifikasi tanah, pengujian pemadatan tanah untuk mendapatkan kadar air optimum, dan pengujian geser langsung untuk mendapatkan nilai kuat geser, semua pengujian menggunakan porsedur berdasarkan standar nasional indonesia (SNI). Hasil penelitian didapatkan bahwa sampel tanah mempunyai kadar air yang tinggi sebesar 34.77% serta memiliki plastisitas tinggi dengan kadar air optimum sebesar 34.37%, pada hasil pengujian uji geser langsung didapatkan bahwa variasi yang paling berpengaruh dengan penambahan semen portland sebanyak 10% dengan nilai kohesi didapatkan sebesar 86.57 kPa, nilai sudut geser dalam sebesar 54.35◦, dan kuat geser sebesar 104.27 kPa. Hal ini menunjukan bahwa semakin besar penambahan variasi semen portland maka semakin berpengaruh terhadap nilai kuat geser, maka bahan tambah dengan semen portland dapat digunakan sebagai bahan stabilisasi tanah yang berpengaruh terhadap kuat geser serta daya dukung tanah

Published: January 2024

Penggunaan beton sebagai material dalam konstruksi bangunan saat ini telah umum digunakan, beton memiliki kelebihan diataranya biaya perawatan yang murah, kemudahan dalam pembentukan, serta memiliki kuat tekan yang tinggi. Susunan beton terdiri dari agregat halus, agregat kasar, semen, air, serta bahan tambah. Penggunaan cangkang kerang dara sebagai substitusi agregat halus dapat memperbaiki sifat-sifat beton serta menaikan kuat tekan beton. Penelitian ini bertujuan untuk mengetahui perbandingan nilai kuat tekan beton normal dengan nilai kuat tekan beton menggunakan cangkang kerang dara sebesar 5%, 10%, dan 15% sebagai subtitusi sebagian agregat halus. Metode yang digunakan dalam penelitian ini menggunakan metode eksperimental di laboratorium. Hasil dari penelitian menunjukkan bahwa semakin tinggi penggunaan cangkang kerang dara sebagai subtitusi sebgaian agregat halus menghasilkan kuat tekan yang semakin tinggi. Hal ini disebabkan oleh cangkang kerang dara memiliki sifat rekat apabila dicampur air pada campuran beton serta memiliki gradasi kategori agak halus sehingga berperan secara optimal sebagai filler dalam campuran beton. Selain itu, cangkang kerang dara memiliki kandungan mineral yang serupa dengan semen sehingga dapat berperan mengisi dan mengikat material penyusun beton lainnya. Dari ketiga variasi subtitusi agregat halus dapat disimpulkan bahwa penggunaan cangkang kerang dara optimum adalah sebesar 15% memiliki nilai kuat tekan tertinggi pada umur 28 hari sebesar 35,45 MPa.

Authors: Mašek Vojtěch 
Published: January 2024

The aim of this review (written in the summer 2023) is to stimulate the critical reflection of policy experts, academics, and civic activists in the field of food security and focus our attention to broader ethical and geopolitical aspects of food security debate. The critical comments of the review particularly refer to the final version of the report _Collective Action for Ending a Collective Problem: A Multi-stakeholder Project on Global Food Security_ published on 23rd July 2023 by the team of the Dublin City University led by Prof Phillip McDonagh. https://www.dcu.ie/sites/default/files/inline-files/Report%20-%20final%20%283%29.pdf

One of the reasons for publishing this review at Queios is that this review was taken out of team discussion by the editors of the Report during its final stage, which seriously reduced the critical debate about its content and about some political-ethical aspects of food security in the current tense historical context, especially with regards to open wounds of the disastrously inhumane Putin´s war against Ukraine. The author of this review welcomes any feedback from both members of the Report team and general public, policy experts, academics or anybody involved in the area of food security theory and practice.

Dryland soils a very high potential land for the development of agricultural crops, including vegetable crops, although the obstacles faced are due to low soil fertility, therefore efforts that can be made to increase production can use mycorrhizal biofertilizers and the use of high-yielding eggplant varieties. Hyphal elongation by mycorrhizal biofertilizer is expected to increase N, P, and K nutrient uptake, growth, and yield of green eggplant and green eggplant varieties can adapt well to less suitable environments. This research was conducted on a farmer's land on Klp Raya Road, Talang Kelapa, Alang-alang Lebar District, South Sumatra Province from March to June 2022. The research used field experiments. The experimental design used RAK Factorial with 6 treatment combinations that were repeated 4 x. Factor 1: Variety (V): Milano (V1), Ratih-Hijau-1 (V2). Factor 2: Mycorrhizal Biofertiliser (M): 5 g (M1), 10 g (M2), 15 g (M3) per plant. The highest eggplant yield was achieved by the Milano variety with mycorrhizal biofertilizer 10 g/plant produce 10.14 kg/plot or equivalent to 27.04 tonnes/ha and increased 93.88% when compared to Ratih Hijau-1 variety with mycorrhizal biofertilizer 5 g/plant.

The increase in infrastructural development in the tropic has led to high demand for concrete production. Consequently, its constituents became very scarce and costly, especially the naturally occurring constituents. Laterite as an abundant naturally occurring material in the tropics is only put in use as filling material or in road construction. This study presents the determination of influence of nominal mix proportion (1:2:4, 1:1.5:3 and 1:1:2) at a constant water cement ratio of 0.5 with laterite fully replacing sand (fine aggregate). 72 numbers of cubes of size 100 mm were prepared for the different concretes, while 12 numbers were cast for each mix proportion and cured in the curing tank at 3, 7, 14, 28 days. Though the laterite was found to be a normal weight aggregate, it was also identified as A – 7 – 6, medium plastic clayey and porous material, with a specific gravity of 2.59. For the fresh concrete, the slump value and degree of workability were obtained using the Vee-bee consistometer and slump tests in both laterite and conventional concrete in all the three mix proportions (1:2:4 : 0.5, 1 : 1.5 : 3 : 0.5, 1 : 1 : 2 : 0.5). The Vee bee second for the mix proportions (1:2:4 , 1:1.5:3 and 1:1:2 ) are 13:18 , 09:44 and 6.0 for the conventional concrete while 14:47 , 12: 41 and 9:30 for Laterized concrete.
ON THE PERFORMANCE OF SARIMA AND SARIMAX MODEL IN FORECASTING MONTHLY AVERAGE RAINFALL IN KOGI STATE, NIGERIA
Authors: Ibrahim A. , Musa A. O. 
Published: January 2024

Forecasting monthly rainfall is very important in Kogi state for better approach to flood management and also plays a pivotal role in agriculture which remains a significant factor in Nigeria’s economy. Advanced time series univariate models such as Seasonal Autoregressive Integrated Moving Average (SARIMA) models are usually employed in modelling and forecasting rainfall in Nigeria due to their non-linear pattern and spatiotemporal variation. Few studies have attempted to investigate the influence of other climatic factors in modelling and prediction of rainfall pattern. This study examines the performance of a univariate seasonal ARIMA and seasonal ARIMA which uses monthly temperature and relative humidity as exogenous factors otherwise known as SARIMAX model in forecasting monthly average rainfall in Lokoja, the capital of Kogi state. The study uses monthly data on rainfall, temperature and relative humidity spanning from 2010 to 2022 obtained from Nigeria Meteorological Agency NiMet, Lokoja station. The series were appropriately differenced to attain stationarity. The plots of autocorrelation function (ACF) and partial autocorrelation function (PACF) were used to select some tentative models whose parameters would be estimated. The most suitable SARIMA model [SARIMA was chosen based on maximum Coefficient of Determination , and the minimum Akaike information criterion (AIC). However, SARIMAX model outperformed SARIMA model based on the criteria earlier highlighted. SARIMAX model was therefore recommended for modelling and forecasting monthly average rainfall in Kogi state.

Objectives: To explore the literature search on cast analysis of deciduous teeth in children for identification of their gender, to describe the validity of cast analysis in gender determination and assess that either a diff erence exists between the deciduous teeth dimensions among girls and boys.
Materials and Methods: Different online databases were used for searching articles in last 12 years, search terms were “gender determination among children using cast analysis”. Only those articles were analyzed for further review which worked on odontometric analysis of deciduous teeth used for gender estimation while we excluded those articles which studied cast analysis on permanent teeth and mixed dentition for gender determination, review articles and case reports.
Results: Three cross sectional studies were included in this research article, based on pediatric population. In all studies deciduous teeth cast analysis was performed. One study showed that maxillary central incisors, lateral incisors, molar and mandibular canine exhibit sexual dimorphism. Other study found that primary molars dimensions were signifi cantly diff erent in both genders. Third study concluded that primary teeth dimensions were greater in male than female.
Conclusion: This study concluded that primary teeth showed sexual dimorphism, so the primary dentition can used in forensic investigation for identifi cation of gender in children.

Ketersediaan air di Bendung Gunungcupu sangat dibutuhkan untuk mendukung berbagai aktivitas masyarakat di daerah layanannya. Penyebab berkurangnya pasokan air bersih salah satunya adalah kerusakan pada pipa akibat bencana alam, seperti yang terjadi pada tahun 2022, telah terjadi banjir bandang luapan Sungai Citanduy yang berlokasi di area Bendung Gunungcupu dan menyebabkan pipa utama transmisi air baku milik PDAM Tirta Galuh Ciamis di Intake Gunungcupu terputus sepanjang 100 meter, akibatnya pasokan air di daerah layanan Bendung Gunugcupu terganggu. Maka dilakukan penelitian ini untuk mengetahui ketersediaan air baku, mengetahui proyeksi kebutuhan air bersih pada tahun 2042, serta mengetahui debit banjir rencana di Bendung Gunungcupu. Metode yang digunakan berupa pendekatan secara kuantitatif. Untuk mengetahui ketersediaan air baku adalah mengolah data debit aktual dengan menggunakan persamaan Weibull, menghitung proyeksi jumlah penduduk menggunakan metode aritmatika dan geometrik, perhitungan kebutuhan air bersih untuk kebutuhan domestik pada tahun 2042, serta mengolah data curah hujan untuk menganalisis debit maksimum rencana menggunakan metode Hidrograf Satuan Sintetis Nakayasu dan Hidrograf Satuan Sintetis Gama I. Hasil perhitungan didapatkan ketersediaan air pada Bendung Gunungcupu adalah 730 liter/detik. Kebutuhan air bersih pada tahun 2042 untuk tiga kecamatan adalah 302,66 liter/detik. Berdasarkan hasil tersebut, pasokan air dari Bendung Gunungcupu dapat memenuhi kebutuhan air bersih untuk Kecamatan Ciamis, Baregbeg, dan Cijeungjing pada tahun 2042. Kemudian debit banjir rencana metode HSS Nakayasu untuk probabilitas Gumbel pada Q100 sebesar 930,484 m3/detik dan untuk probabilitas Log Normal pada Q100 sebesar 786,302 m3/detik, sedangkan debit banjir rencana metode HSS Gama I untuk probabilitas Gumbel pada Q100 sebesar 833,381 m3/detik dan untuk probabilitas Log Normal pada Q100 sebesar 707,002 m3/detik. Berdasarkan hasil tersebut dapat disimpulkan bahwa debit maksimum terbesar adalah metode HSS Nakayasu untuk probabilitas Gumbel, maka metode HSS Nakayasu baik digunakan untuk perencanaan keamanan bangunan air terhadap banjir.

Mothers with prolonged labor have a higher risk of bleeding. This study aimed to determine the effect of the counterpressure technique with a birthball on the length of the first stage of perineal rupture. This type of research is quantitative with a quasi-experimental design using an observation form conducted in Kendari City Hospital from May to August 2023. The design used was a two-group-only post-test, with a control group. The study population comprised multiparous mothers in the first active stage. The sample size consisting of 20 who were given the counterpressure technique with birthball, 20 who were only given the counterpressure technique, and 20 who received no treatment. The inclusion criteria were mothers who were willing to become respondents and mothers who gave birth with normal births. The samples were collected using purposive sampling. The t-test was used to determine the differences between the three groups. The results of the difference test in the length of active phase I between the group given the counterpressure technique with birthball (intervention I) and the control group were p-value (0.000). The results of the analysis for the group given the counterpressure technique (Intervention II) with the control group were p-value (0.000). The results of the analysis for the group given the counterpressure technique with birthball (Intervention I) with the counterpressure technique (Intervention II) were p-value (0.759). In Conclusions, Providing counterpressure techniques with a birthball or simply providing counterpressure techniques is effective in reducing the incidence of perineal ruptures.

Introduction: Clear aligners, while offering a more hygienic alternative to fixed appliances, are still associated with challenges including plaque accumulation and enamel demineralization. The aim of the present study was to investigate the antibiofilm and remineralization effectiveness of innovative flowable composite attachments containing bioceramic micro-fillers.Methods: Four experimental attachments were formulated and bonded to human enamel specimens: 3M Filtek Supreme flowable composite (Filtek SF) + 10% bioactive glass 45S5 (BAG), Filtek SF + 30% BAG, Filtek SF + 10% Bredigite (BRT), Filtek SF + 30% BRT. Plaque biofilms were grown on the bonded enamel using a standardized protocol and the biofilm-killing effect was assessed by confocal laser scanning microscopy and scanning electron microscopy. Vickers microhardness was measured to evaluate the remineralization effect of the attachments containing bioceramic fillers after acid challenge. Shear bond test was performed to assess the bonding strength.Results: Attachments with bioceramic fillers significantly inhibited plaque biofilm growth in 3 weeks on enamel, contributing over 20% bacterial cell killing in 10% filler groups and over 30% killing in 30% filler groups. All four experimental groups demonstrated significantly higher microhardness values than the control group without fillers on the attachment side. The shear bonding strength was not compromised in the attachments with micro-fillers.Discussion: Proper incorporation of bioceramic micro-fillers in attachments provides an innovative approach for clear aligner therapy with reinforced antibiofilm and remineralization effects without weakening shear bonding strength.
