Students’ ability to communicate their mathematical ideas in various ways is not as expected. It is difficult for teachers to improve students’ mathematical communication skills by improving learning styles, improving the learning atmosphere, and using appropriate learning models. Therefore, it is important to know the factors that influence students’ mathematical communication abilities. The aim of this research is to describe the factors that influence students’ mathematical communication skills. The subjects of this research were four children aged approximately 11 years who live in Hamparan Perak District. The data collection techniques used were observation and interviews. Data were analyzed using a qualitative approach. The results of the research show that the factors that influence students’ oral communication skills are study partners, self-confidence, shyness, nervousness, group learning atmosphere, learning time, and gender. Factors that influence students’ written communication skills include the inability to write down known information and be asked about it, lack of concentration in studying and inability to understand the content, as well as question difficulty, which includes the level of composure and composure in solving questions.

Advances in science and technology are faced with a number of challenges, one of which is preserving the environment which is faced with the use of synthetic materials. Synthetic materials are basically materials that cannot be decomposed naturally and pollute the environment. Therefore, a number of research and developments have been carried out in utilizing more environmentally friendly materials through the manufacture of biocomposites. However, the use of biocomposites has not been able to replace the use of synthetic materials as a whole, due to the weak bonding of the fiber-matrix interface (adhesion between fiber and matrix) in biocomposites. One effort that can be made to increase fiber-matrix interfacial bonding in biocomposites is through modification of natural fibers using NaOH. A number of studies have been carried out using NaOH to modify the fiber-matrix surface. The results obtained through a number of studies state that each natural fiber has a different response to NaOH concentration, so that each natural fiber requires a certain concentration to increase the bond between the fiber-matrix interface in biocomposites.

Background: Ointment is a semisolid preparation used as a topical medicine, which has direct access to the skin tissues. Katang-katang is one of the medicinal plants traditionally used to treat various types of wounds. Objective: The aim of this study is to identify the secondary metabolite content of katang-katang leaves (Ipomoea pescaprae L.), create and evaluate a good and stable ointment formulation pharmaceutically, and test the irritation of the ointment for burn wounds using ethanol extract of katang-katang leaves (Ipomoea pescaprae L.). Method: The method used is experimental research, the ointment formulation is made using three formulations with different concentrations of active ingredients, with a ratio of FI 20%, FII 25%, and FIII 30%. Result: The results of the study indicate that katang-katang leaves contain flavonoids, tannins, and steroids. The study determined the formulation of a burn ointment from ethanol extract of katang-katang leaves (Ipomoea pescaprae L.). The organoleptic test results of FI, FII, and FIII showed good and stable color, odor, and shape, as well as homogeneity after one week of storage. The pH values measured were 7 for all formulations even after one week of storage. The spreading power of FI was (5.52 cm), FII was (5.88 cm), and FIII was (7.23 cm), which met the standards for good formulation. The irritation tests for all three formulas were categorized as safe. Conclusion: Based on the identification test results, the katang-katang leaves were found to contain flavonoids, tannins, and steroids. The evaluation test results for the three formulations using a hydrocarbon base showed that a good and stable burn ointment could be made from the ethanol extract of katang-katang leaves (Ipomoea pescaprae L.) without causing skin irritation.

Sweet arum mango is one type of mango which when harvested has the highest vitamin C content of 7.53 ± 0.4 mg / 100 g. Processed sweet arum mango fruit products that have the potential to be developed are in the form of fruit juice. This is a consideration for researchers to conduct further research on the addition of eugenol preservatives with different concentrations of preservatives and storage times to produce better mango juice. Eugenol compounds have pharmacological activities as analgesics, anti-inflammatory, antimicrobial, antifungal, antiseptic, stimulant, so these compounds are widely used in the pharmaceutical industry. Based on the experimental results, optimal conditions for the use of eugenol occurred until day 2, where the addition of eugenol with treatment 3 as much as 1 ml amounted to 38.82% better when compared to other variations of eugenol addition.  The addition of eugenol preservatives cannot preserve the content of vitamin C in sweet mango juice even the content of vitamin C tends to decrease. Sweet arum mango juice has a shelf life of 12 days and total dissolved solids of more than 20%, so the resulting fruit juice does not meet SNI 7382:2009.

Industry concentration is centered on the number and size distribution of companies. In this case it can be said that the fewer the number of companies in the market, the level of industry concentration tends to be linked to the ability of sellers (producers) in the market. This can be a form of suppressing competition and coordinating price policies which tend to be high.

Sektor pertanian, terutama produksi tanaman pangan merupakan pilar perekonomian di Indonesia dengan sentra produksi berada di Nusa Tenggara. Salah satu penyebab penurunan produksi tanaman pangan adalah kekeringan yang disebabkan oleh perubahan iklim. Kekeringan dapat dihitung dengan Standardized Precipitation Index yang merupakan indeks untuk mengukur tingkat keparahan kekeringan suatu wilayah. Tingkat keparahan kekeringan suatu wilayah dapat mencapai nilai tertinggi yang dapat digunakan untuk memperkirakan periode kejadian kekeringan yang terjadi secara berulang. Selanjutnya hasil estimasi tersebut dapat digunakan untuk memperoleh nilai Return Period yang merupakan rata-rata waktu kekeringan yang terjadi dengan menentukan keparahan kekeringan maksimum. Untuk mengantisipasi kekeringan yang terjadi secara berulang, tujuan dari penelitian ini adalah melakukan identifikasi karakteristik kekeringan dari Return Period berdasarkan profil geografis Nusa Tenggara. Data yang digunakan adalah data observasi curah hujan bulanan selama periode tahun 1985 sampai 2014 yang menggambarkan kejadian kekeringan yang telah terjadi untuk masa sekarang dan data skenario curah hujan bulanan selama periode tahun 2016 sampai 2100 berdasarkan Representative Concentration Pathways yang menggambarkan iklim di masa akan datang. Hasil analisis data menunjukkan bahwa Return Period secara geografis memberikan gambaran untuk berbagai wilayah. Pada wilayah karakteristik iklim lebih basah terlihat adanya pengurangan curah hujan, sedangkan wilayah karakteristik iklim lebih kering tidak mengalami pengurangan curah hujan yang signifikan. Secara umum dapat diketahui bahwa beberapa tahun ke depan prediksi kekeringan Pulau Nusa Tenggara menunjukkan tingkat keparahan kekeringan yang tidak terlalu parah dengan periode berulang yang lebih sering terjadi.

Body odour is a problem that interferes with daily life. The secretion of sweat glands and bacterial activity cause body odour.

Companies perceive taxes as a burdensome expense, which can diminish potential profits. As corporate taxpayers, companies have a responsibility to pay taxes in accordance with applicable laws. Tax aggressiveness refers to tactics employed by companies to manage or manipulate the magnitude of the tax burden they must bear, aiming to reduce their actual tax obligations without violating the law. This research examines the relationship between ownership concentration, tax risk, and corporate risk on tax aggressiveness, with accrual earnings management as a moderation variable. Data analysis is conducted using descriptive statistics with a quantitative approach. The research findings indicate that ownership concentration, tax risk, and corporate risk positively influence tax aggressiveness. Additionally, accrual earnings management can weaken the impact of ownership concentration, tax risk, and corporate risk on tax aggressiveness.

Arumanis mango seeds (Mangifera indica L.) are organic waste, which in previous research contained many secondary metabolite compounds such as flavonoids and had very strong antioxidant activity.

: This article introduces a community service conducted by the PkM ITERA team in Hanau Berak Village, Pesawaran Regency, Lampung. Nutmeg, being a primary agricultural commodity in this region, reveals an underutilized surplus of nutmeg flesh, leading to organic waste accumulation. In response to the urgent need for minimizing organic waste and elevating the economic viability of nutmeg fruit flesh, this endeavor is driven by the realization that this waste represents an overlooked potential. Nutmeg flesh possesses intrinsic qualities, notably a rich concentration of antioxidants known for their role in promoting skin health, stabilizing cardiac rhythms, mitigating insomnia, alleviating angina, enhancing digestive processes, improving blood circulation, increasing appetite, and fortifying the immune system. The proposed solution involves the creation of nutmeg-flavored tea, intended to mitigate the issue of excess nutmeg fruit waste while simultaneously augmenting the economic worth of the produced merchandise. Thus, this initiative materializes as a strategy to optimize nutmeg fruit utilization, curtail waste generation, and amplify its market value. The Community Partnership Program administered by the ITERA team serves as a conduit for the enrichment of knowledge, insights, and competencies among local nutmeg farmers, empowering them to generate high-value commodities from an underexploited resource. The scope of activities encompasses the entire production process, extending to packaging design.
