Abstract

The addition of aluminum (Al) to the alloy system can improve corrosion and oxidation resistance but has the disadvantage of having brittle properties, the austemper process can increase strength, toughness, reduce distortion and reduce brittle properties. The stages of the austemper process start from heating at 900oC for 1 hour, then continued immersion in molten salt (KNO3 55% + NaNO3 45%) at temperatures of 300oC, 350oC, and 400oC, for 20 minutes and continued immersion in water media. The tests carried out were microstructure tests using an optical microscope, hardness tests using the Brinnel method, and tensile strength tests. The chemical composition test results show that the Fe-Al-C alloy contains the main element Fe by 89.40%, and the main alloying element Al by 0.98%, C 5.41%, Si 1.69%, including Al alloy cast iron, Fe-Al-C alloy has a hardness of 188.2 Kg/mm2. After austemper process hardness rose to 325.4 Kg/mm2 at 300 ° C, this is due to the change of pearlite structure into bainite structure. The tensile test results show that the Fe-Al-C alloy has a tensile stress of 188.2 Mpa and a strain value of 1.1% and then drops at austemper temperature of 300 ° C with a tensile stress value of 44 Mpa and a strain of 0.4%, this is due to the large graphite structure and fractures and the presence of bainite structures.

Abstract

Rural development in Indonesia has currently received special attention from the government. The importance of village data in the rural development planning process means that rural’s governments must strive to provide data related to the specific characteristics of their area. This can be realized in the making of rural profile. Implementation stages include preparing instruments, forming working groups, collecting and validating data assisted by the community (a form of participation activity). Furthermore, data processing will be carried out through clarification, tabulation, compilation and recapitulation either through application programs or manually. The final stage is publication which will be carried out via online media. Kebonharjo sub-district consists of 10 pedukuhan, has an area of ​​746.92 hectares, population of 2,376 people with the main source of income is in agriculture. Geographically, Kalurahan Kebonharjo has most of the landforms tend to be hilly with an average land slope of 38 degrees.

Abstract

Most of the Gunungkidul district area is dry, barren rain-fed land with an area of ​​42,000 ha and a fairly high average rainfall of 1889.66 mm/year. So far, this rainfall can only be utilized during the rainy season, while during the dry season there is still a shortage of water because the excess rainwater flows directly on the surface and the rest is absorbed into the soil. The purpose of this study is to convert dry land into land for date palm plantations and their intercrops by maximizing the use of rainwater so that it is expected to maximize the socio-economic welfare of the surrounding community. With the Rain Driphonics System (RDS) method, the rainwater that falls is collected in reservoirs to then be channeled into the main reservoir pool, which is then pumped into the main reservoir pool and after adding liquid fertilizer from the water mixing tank, it is then channeled by gravity to the plantation land through the drip irrigation system. The analysis was carried out by calculating the amount of rainwater and then implementing it in the plantation demonstration plot. Based on the results of rainfall calculations, the highest mainstay discharge was obtained in January-II of 56.88 lt/sec, while the average water requirement for 40 main plants/date palms and intercrops was 0.08 lt/sec and by using a storage volume of 102 m3 and water savings, it can meet the needs for 1 year. So it can be concluded that by using RDS, it is proven that rainwater that falls in the rainy season can also be utilized in the dry season or in other words, rainwater that falls in the rainy season can be utilized throughout the year.

Abstract

Technological developments often affect the way residential buildings adapt to the environment. This is reflected in the appearance of building facades. This article presents a comparison of the development of modular houses in adapting to the environment along with technological developments. The focus of the study is more on the appearance of building facades. The analysis was carried out using a qualitative descriptive approach. The focus of the study is: (1) the development of modular houses before the industrialization era, (2) the development of modular houses before the mass industry era, (3) the development of modular houses in the digital technology era. Data collection was obtained from secondary data in the form of articles, books, seminar papers. Case studies through several case samples (case multiple) to provide examples of practice. The results of the study found that adaptive modular houses have been developed both in traditional architecture, mass industry era architecture, and the digital technology era. Traditional architectural modular houses in adapting to the environment are more static. Digital technology provides opportunities for the development of modular houses and their elements that are more dynamic (flexible), complex and integrated.

Abstract

The financial management training program based on simple mathematical principles was conducted in Padukuhan Dobalan, Kapanewon Timbulharjo, Bantul Regency. This initiative aimed to improve the financial literacy of the rural community, especially in preparing for potential economic recession. Most of the residents work as farmers and laborers, making them vulnerable to global economic changes. The program introduced the use of basic mathematical operations addition, subtraction, multiplication, and division to create budgets, track expenses, and make sound financial decisions.The training employed pretests and posttests to measure participants' progress. The results showed a significant improvement in the participants' ability to manage their finances and adopt positive mindsets, as indicated by higher posttest scores compared to pretest scores. The program also encouraged participants to reduce unnecessary expenses, seek additional income sources, invest for future growth, and share their wealth through charity.Overall, the program had a positive impact on the participants’ financial management skills and household economic resilience. However, some participants may still require further guidance to achieve maximum results. This initiative is expected to continue and serve as a model for empowering communities to face economic challenges more wisely and strategically.

Abstract

Data curah hujan bisa didapatkan dari berbagai sumber, antara lain pembacaan satelit maupun data lapangan. penelitian ini bertujuan membandingkan data curah hujan Sungai Anai meggunakan data satelit dan data lapangan untuk memprediksi debit banjir. Dalam proses memperoleh data pembacaan satelit, data curah hujan diunduh dari sumber online, yaitu Japan Aerospace Exploration Agency (JAXA) sedangkan data lapangan diperoleh langsung dari stasiun pengukur curah hujan (PCH) di lokasi studi. Data dari kedua sumber ini kemudian dibandingkan, dengan periode tahun data hujan yang sama yakni selama 10 tahun dari tahun 2013-2022. Dalam analisis statistik menunjukkan adanya selisih signifikan antara data website dan data stasiun hujan, di mana hasil curah hujan rata-rata dari website cenderung lebih rendah dibandingkan hasil pengukuran lapangan. Temuan ini mengindikasikan adanya perbedaan akurasi antara data satelit dan data lapangan, terutama pada periode hujan tinggi, dan diharapkan dapat memberikan pemahaman yang lebih baik dalam memilih sumber data yang sesuai untuk studi hidrologi.
