“…The rice husk utilized in this investigation was acquired from a rice mill located near the campus in Semarang, Indonesia. In general, the basic content of rice husk consists of cellulose, hemicellulose, acid‐soluble lignin, acid‐insoluble lignin, ash, and extractive substances of 31.13%, 17.71%, 3.36%, 24.89%, 16.50%, and 5.01%, respectively 34–36 . For the production of rice husk powder, the rice husk was crushed and sieved through a 100‐mesh sieve.…”

The need to comply with environmental regulations and provisions set by the government for sustainability and environmental awareness has caused the use of natural fiber‐reinforced composites in the automotive industry to increase. Furthermore, there has been a lack of extensive research on the production of eco‐friendly composites for automotive applications utilizing epoxy resin, rice husk, Al2O3, and Fe2O3 by the compression molding technique. Therefore, the objective of this study is to determine the influence of compression molding pressure on the properties of eco‐friendly composites for automotive applications. The specimens consisted of epoxy resin, rice husk, Al2O3, and Fe2O3, in that order by weight percentages of 50%, 20%, 15%, and 15%, respectively. Compression molding with pressures of 10, 20, and 30 MPa and a holding time of 20 min at room temperature was utilized in this study. To evaluate the properties of the obtained specimens, density, hardness, flexural, wear, TGA (thermal gravimetric analysis), and DSC (differential scanning calorimetry) tests were conducted. The research findings show that composite specimens' physical and mechanical properties decrease while the friction coefficient increases with increasing pressure during compression molding. In contrast, the pressure increase did not significantly alter the thermal characteristics of the composite specimens. The BP_10 specimen, fabricated at a molding pressure of 10 MPa, exhibited superior properties compared to other specimens. Density, hardness, flexural strength, coefficient of friction, total residue, Tmax, Tg, and Tc in specimen BP_10 was 1.881 g/cm3, 80.5 shore D, 35.84 MPa, 0.262, 58.67%, 354.87, 285.53, and 497.7°C, respectively.Highlights The demand for natural fiber‐reinforced composites is increasing because more vehicles are on the road. The properties of natural fiber‐reinforced composites are strongly influenced by the pressure applied during compression molding. Results show that compression molding pressure strongly influenced the hardness, density, flexural strength, friction coefficient, and thermal stability of natural fiber‐reinforced composites. The natural fiber‐reinforced composites developed in this research can contribute to several Sustainable Development Goals (SDGs).

“…Pemilihan bahan organik didasarkan pada kandungan dalam bahan tersebut serta kemuda-hannya untuk diperoleh. Dalam hal ini, bahan organik yang digunakan adalah sekam dengan kandungan 35,68% serat kasar, 33,71% karbohidrat, 33,64% oksigen, 17,17% abu, 16,98% silica, 9,02 air, 1,54% hydrogen, 1,33% karbon, dan 1,18% lemak (Mahfuzin et al 2020). Aplikasi sekam diharapkan mampu mening-katkan serapan unsur hara melalui ketersediaan oksigen dalam jumlah cukup pada media tanam air akibat tingginya kandungan oksigen dalam sekam.…”

“…Selaras dengan pernyataan Tilahun (2019), kondisi nutrisi, suhu, dan radiasi yang merupakan faktor lingkungan dapat memengaruhi pembentukan anakan padi. Dalam hal ini, sekam dengan kandungan oksigen mencapai 33,64% (Mahfuzin et al 2020) dapat meningkatkan ketersedian oksigen dalam media tanam sehingga kondisi unsur hara yang tersedia dengan baik dapat diserap secara maksimal oleh akar. Selain dipengaruhi oleh faktor lingkungan, jumlah anakan yang terbentuk pada tanaman padi dipengaruhi pula oleh varietas (Hadi et al 2020).…”

Rice cultivation without land as an urban farming method is carried out to produce food in a subsistence manner. This experiment aimed to examine the response of rice plants to non-soil planting media based on alternate wetting-drying irrigation. This work was conducted at the screen house in Sumberjeruk Village, Jember Regency (8°07'42.9" S and 113°47'09.3" E) from January to May 2022, using a factorial, fully randomized design of 2-factors with 3-replications. The planting medium without soil (husk:water) as the first factor consists of 4 compositions (v/v): 0:1, 1:4, 1:6, and 1:8 (total volume of 25-L media), while variety as the second factor consists of Inpari 46 and IR 64. The results showed that the combination treatment (husk: water) 1:6 and Inpari 46 had a significant effect on the number of productive tillers (25.17 stems) and grain weight per hill (34.07 g). The planting medium of non-soil husk: water 1:6 gave no significant value to husk: water 1:4 on the total number of grains (124.21 grains) and full grains (83.52 grains). The Inpari 46 varieties showed the highest value for the total number of grains (133.07 grains), the number of full grains (84.88 grains), and the weight of 1000-seeds (22.43 g). The application of husks and water as a planting medium with the right ratio is an ideal medium for landless rice cultivation since it can supply oxygen to the media.

“…Penambahan karbon aktif ke dalam campuran keramik akan mengurangi nilai densitas dan meningkatkan nilai porositas [15] [16]. Hal ini dikarenakan semakin besar konsentrasi karbon aktif yang digunakan maka akan menghasilkan ukuran pori yang lebih besar yang dihasilkan dari karbon aktif yang terbakar saat proses pembakaran sampel [15]. Besarnya ukuran pori yang dihasilkan bergantung dengan banyaknya komposisi karbon aktif yang digunakan pada material.…”

Purbalingga adalah salah satu daerah pengasil teko teh poci terbesar di Indonesia. Tetapi produk yang dihasilkan rentan pecah dan memiliki zat terlarut sehingga kualitas produk cukup rentan dalam ketatnya persaingan pasar. Maka dari itu dilakukan inovasi peningkatan kualitas teko teh poci dengan memperkuat sifat kekerasan dan mengurangi zat terlarut pada teko teh poci dengan menambahkan alumina dan karbon aktif ke dalam tanah liat sebagai bahan dasar pembuatan teko teh poci. Tujuan dari paper ini adalah mengetahui pengaruh penambahan alumina dan karbon aktif ke dalam tanah liat. Metode yang digunakan pada paper ini adalah studi literatur terhadap penelitian terkait. Hasil yang didapat adalah material alumina akan menambahkan kekerasan material tanah liat dengan menaikkan nilai densitas dan mengurangi porositas sehingga material semakin padat. Semakin tinggi konsentrasi alumina dan suhu yang digunakan akan menaikan kekerasan material. Sedangkan penambahan karbon aktif ke dalam tanah liat akan menaikan porositas seiring dengan meningkatnya konsentrasi yang digunakan dan menghasilkan uji TDS yang lebih baik.
