Indonesia is a country with a high level of earthquake vulnerability, thus demanding innovation in building structural engineering that is not only safe but also environmentally friendly. In the context of sustainable development, bamboo as an abundant local material is starting to gain attention as an alternative to conventional materials. Bamboo, when processed into composites in the form of fibers or in combination with thermoplastic and thermoset polymers, has been proven to have superior mechanical properties, including tensile strength, stiffness, and resistance to chemical degradation. In addition, the characteristics of water absorption that are controlled through certain treatments make bamboo composites more competitive compared to synthetic materials. The application of bamboo composites in construction is not only limited to new materials in structural elements, but also effective in retrofitting methods. For example, recent research shows the potential of bamboo composites in strengthening reinforced concrete beams and improving the performance of frame systems in earthquake-resistant structures. In line with this, seismic design regulations and standards such as the comparison between SNI 1726:2012 and SNI 1726:2019 demonstrate the importance of adapting structural designs to local seismic conditions. The integration of bamboo composite materials with structural capacity analysis, numerical simulation, and pushover analysis methods has yielded promising results for improving building resilience to dynamic loads. Beyond technical aspects, this approach also supports environmental objectives. Several studies have even developed eco-friendly home prototypes utilizing innovative material combinations, including geopolymer blocks and natural fibers. Thus, the use of bamboo composites not only provides a technical solution to earthquake challenges but also contributes to global efforts to reduce the carbon footprint of the construction sector.

Mung bean and sago composite flour cookies are cookies made from the main raw material of wheat flour which is composited with mung bean and sago flour to reduce the use of wheat flour and to increase nutritional content. This experiment aims to determine 1) the sensory quality of mung bean and sago composite flour cookies including shape, color, aroma, crispness, crumb, and taste 2) chemical properties based on laboratory tests which include carbohydrates, protein, fat, ash, and fiber 3) the cost of raw materials for mung bean and sago composite flour cookies. This type of research is a factorial experiment. The independent variable was the proportion of mung bean composite flour (35%, 25%, and 15%) and sago (15%, 25%, and 35%) that had gone through the starch calculation stage. The dependent variable is sensory quality which includes shape, color, aroma, crispness, crumb, and taste. The control variables of this study include the type of materials and equipment. Observation data collection technique by means of sensory quality test conducted by 35 panelists. Data analysis used single anova test and continued with Duncan test.  The results showed 1) there was an influence on the sensory quality of composite flour cookies which included aroma, crispness, crumb, and taste 2) there was no influence on sensory quality in shape and color 3) the best product had a raw material cost of Rp 8,473/250 grams.    

Morphology is one of the linguistic sciences that discusses the ins and outs of word formation such as compositum. Compositum is a combination of two words but the elements of compositum can be two or more words. Compositum has a word component as its forming element which has a special pattern so that it is different from other word combinations, such as idioms and phrases. The difference can be seen in terms of the level of meaning. Compositum can be classified into several types, namely based on the cohesiveness of meaning, the type of words of the elements, the distribution system, the complexity, and the language origin of the elements. Based on the cohesiveness of meaning, compositum consists of semicompound and non-compound compositum. Semicompound compositum is a compound word whose meaning is still related to the meaning of one of its elements. Meanwhile, a non-compound (tenuous) compositum is a compound word whose meaning is still related to the meaning of all its elements. Thus, many readers still do not know how semicompound and uncompound composites can be formed in Kahlil Gibran's poetry collection. In learning, there are still many educators who have not conveyed about compositum so that students do not know and have difficulty in determining compositum. Descriptive qualitative is the method used in this research. The purpose of this research is to analyze and describe semi-compound and non-compound compositum in a collection of poems by Kahlil Gibran. Based on the results of the analysis, there are 33 data including compositum based on the unity of meaning, namely 11 data showing semicompound compositum and 22 data including non-compound compositum.  

Perkembangan zaman semakin pesat, tak hanya pada bidang teknologi namun juga pada bidang industri. Dengan adanya perkembangan industri hal ini menyebabkan kebutuhan akan material semakin meningkat terutama untuk sebuah produk. Sekarang ini salah satu material yang banyak dikembangkan adalah komposit, komposit adalah gabungan dari dua bahan atau lebih komponen yang berlainan dan mempunyai sifat yang berbeda. Komposit terdiri dari dua bagian, yaitu matrik sebagai pengikat atau pelindung komposit dan filler sebagai pengisi komposit. Serat alam merupakan alternatif filler komposit untuk berbagai komposit polimer karena keunggulannya dibanding serat sintetis. Pohon pisang adalah tanaman paling banyak dijumpai dan tumbuh subur di Indonesia. Pelepah pisang jika diolah kembali akan menjadi serat dengan kekuatan yang tinggi dan daya serapnya lebih bagus sehingga sangat baik jika digunakan sebagai bahan penguat pada komposit. Penelitian ini dilakuan menggunakan metode penelitian yang memiliki sifat percobaan (experimental) dengan tujuan untuk menguji sifat mekanik komposit.
