Abstract

Kelompok Wanita Tani Wana Lestari in Dara Kunci Village, Sambelia District, East Lombok Regency, is a productive community group engaged in cashew production within a Community Forestry area. The main challenges faced by the group include the limited utilization of cashew apples, inadequate processing technology, limited skills in operating processing machinery, and conventional marketing practices. Developing cashew-based products is socially and economically important to increase value-added production through the utilization of cashew pulp, skin, and kernels, while also creating business opportunities, increasing household income, and strengthening the community’s economic self-reliance. This Community Service Program aimed to enhance production capacity, processing skills, and digital marketing capabilities through the application of appropriate technology. The program employed a participatory approach involving socialization, training, technology demonstrations, hands-on practice, mentoring, and evaluation involving 30 group members. The technologies introduced included a cashew nut shelling machine, drying oven, and packaging machine, accompanied by training in cashew nut processing and cashew apple floss production. The evaluation results demonstrated a significant increase in knowledge of processing technology, from 20% to 100%, and in machinery operation skills, from 10% to 100%. The partners successfully produced various flavored cashew nut products and cashew apple floss with attractive packaging and market-ready presentation. Overall, the program improved human resource capacity, increased product value-added, and strengthened the competitiveness of micro, small, and medium-sized enterprises (MSMEs) through product diversification and digital marketing.

Abstract

This study aimed to optimize the composition of interlocking bricks made from local Andosol soil and fly ash to achieve the highest compressive strength within the investigated composition ranges while limiting cement content. A Taguchi L27 orthogonal array was used to investigate three factors: fly ash (0%, 8%, and 16%), cement (6%, 8%, and 10%), and sand (0%, 2%, and 4%). Andosol soil constituted at least 70% of the mixture. The 27 treatment combinations, each with three replications, produced 81 specimens tested at 28 days. Compressive strength ranged from 0.40 to 2.00 MPa, with an overall mean of 0.78 MPa. Response analysis, signal-to-noise (S/N) ratio analysis, analysis of variance (ANOVA), and factor interaction analysis identified cement as the most influential factor, contributing 29.04%. The final composition differed from the main-effect candidate because factor interactions were also considered. The selected composition comprised 80% Andosol soil, 8% fly ash, 10% cement, and 2% sand. The predicted compressive strength was 1.62 MPa, while the confirmation experiment yielded an average of 1.77 MPa, with a relative error of 8.74%. These results demonstrate the applicability of the Taguchi method for optimizing the compressive strength of Andosol-based interlocking bricks.

Abstract

Concrete with lightweight aggregates is a type of concrete that is widely used in earthquake-prone areas. One of the building blocks for lightweight concrete utilizing waste is Styrofoam. Styrofoam in lightweight concrete began to be widely used in structural buildings. Self-compacting concrete is a type of concrete that can flow by itself without experiencing segregation. Light aggregate concrete is applied to self-compacting concrete in order to get benefits from an economic and construction time perspective, thereby saving costs and processing time. This study aimed to determine the ductility level of concrete seen from the magnitude of the stress and strain values at each ALWA content as a substitute for gravel in regular and self-compacting concrete. The loading of a concrete cylinder affects the relationship between stress and strain. Variations in the composition of ALWA substituted in concrete, from 0%, 15%, 50%, to 100%. The test was carried out as compressive strength with a cylindrical specimen with a height dimension of 200 mm and a diameter of 100 mm. The results of the test show that the strain values of 0.5f'c at SCC0, SCC15, SCC50, and SCC100 are 0.00140, 0.00140, 0.00146, 0.00151, the higher the ALWA substituted in the SCC mixture, the greater the strain value. In addition, the higher the amount of substituted ALWA in the SCC mixture, the lower the level of workability. This study shows that lightweight aggregate with Styrofoam can make concrete more ductile.ABSTRAKBeton dengan agregat ringan merupakan salah satu jenis beton yang banyak digunakan pada daerah rawan gempa. Bahan penyusun beton ringan dengan memanfaatkan limbah salah satunya berbahan Styrofoam. Penggunaan styrofoam pada beton ringan mulai banyak digunakan pada bangunan yang bersifat struktur. Beton memadat sendiri adalah jenis beton yang memiliki kemampuan untuk mengalir dengan sendirinya tanpa mengalami segregasi. Beton beragregat ringan diaplikasikan pada beton memadat sendiri agar mendapatkan manfaat dari segi ekonomi dan waktu pelaksanaan konstruksi, sehingga lebih menghemat biaya dan waktu pengerjaan. Tujuan penelitian ini untuk mengetahui tingkat daktilitas beton dilihat dari besarnya nilai tegangan dan regangan pada setiap kadar ALWA sebagai pengganti kerikil pada beton normal dan beton memadat sendiri. Pembebanan suatu silinder beton mempengaruhi hubungan antara tegangan dan regangan. Variasi komposisi ALWA yang disubstitusi pada beton yaitu dari 0%, 15%, 50% sampai 100%. Pengujian yang dilakukan berupa kuat tekan dengan benda uji berbentuk silinder dimensi tinggi 200 mm dan diameter 100 mm. Hasil dari pengujian menunjukkan nilai regangan 0.5f’c pada SCC0, SCC15, SCC50, SCC100 nilainya yaitu 0.00140, 0.00140, 0.00146, 0.00151, semakin tinggi ALWA yang disubstitusi dalam campuran SCC maka semakin besar nilai regangannya. Selain itu, semakin tinggi jumlah ALWA yang disubstitusi dalam campuran SCC maka semakin rendah tingkat workability. Penelitian ini menunjukkan penggunaan agregat ringan dengan styrofoam dapat menjadikan beton lebih daktail daripada sebelumnya.
