Pelatihan Pengolahan Sampah Plastik menjadi Produk Kursi Furnitur di Bank Sampah Dusun Rejosari, Srimartani, Bantul
Full text linkPlastic waste is a material that is difficult to decompose in nature, making it harmful to the environment. Therefore, proper management is necessary, one of which is through a waste bank. The Dusun Rejosari, Srimartani, Piyungan, Bantul Waste Bank was established in 2024. This waste bank sorts different types of waste to be sold to collectors, aiming to improve the community's economy. However, a major challenge faced by the community is that plastic waste has not been processed optimally—it has only been sorted and sold to collectors. This community service activity (PKM) aims to address this issue by processing plastic waste into furniture products, thereby increasing its value. The activities include lectures, discussions, training, and mentoring on furniture-making techniques. The process of converting plastic waste into furniture chairs was carried out by four instructors and four assistant instructors, with 25 participants who are members of the Dusun Rejosari Waste Bank. As a result of this activity, participants gained knowledge and skills in processing plastic waste into furniture chairs. The community is expected to apply this training to enhance their income. Based on the evaluation results, the participant's comprehension of the material improved, as reflected in the increase in test scores from 70.43 (initial test) to 77.83 (final test)
PENGARUH FAKTOR INTERNAL TERHADAP HARGA SAHAM PADA PERUSAHAAN PERTAMBANGAN YANG TERDAFTAR DI BURSA EFEK INDONESIA (BEI 2020-2024)
Full text linkThis study aims to analyze the influence of internal corporate factors on stock prices in the mining sector listed on the Indonesia Stock Exchange (IDX) during the period 2020–2024. The internal factors examined include liquidity ratio represented by the Current Ratio (CR), profitability through Return on Equity (ROE) and Earnings Per Share (EPS), and capital structure through the Debt to Equity Ratio (DER). This research employs a quantitative approach using multiple linear regression analysis, preceded by classical assumption testing to ensure the validity of the estimation model. The population includes 62 mining companies listed on the IDX, with sample selection conducted using purposive sampling based on specific criteria. The simultaneous (F-test) results indicate that the four independent variables collectively have a significant effect on stock prices. The partial (t-test) results show that ROE and EPS have a significant individual influence, while CR and DER demonstrate varying effects depending on the financial characteristics of each entity. The coefficient of determination (R²) suggests that these internal factors provide a strong explanatory power for stock price variations, although external factors also influence stock price dynamics. These findings offer important implications for corporate management to enhance internal financial performance as a strategic tool for increasing market value, and for investors in evaluating investment feasibility based on fundamental indicators

Pelatihan Jurnalistik Dasar untuk Pelajar SMK di Bandongan Magelang
Full text linkDari hasil observasi didapati bahwa di SMK Muhammadiyah Bandongan masih belum ada gerakan atau aktivitas jurnalistik yang mapan. Hal ini ditakutkan akan menyebabkan komunikasi publik di lingkungan sekolah tidak produktif dan malah destruktif. Oleh sebab itu, tim pengusul meyakini perlu adanya upaya meningkatkan pemahaman dan keterampilan jurnalistik guna menumbuhkan pola komunikasi publik yang produktif dan sehat. Kegiatan pengabdian ini bertujuan untuk memberi pemahaman tentang jurnalistik dasar yang diharapkan dapat dijadikan bekal dalam menerima berita dan/atau informasi dari media massa. Selain itu, pengabdian ini dimaksudkan untuk membekali target sasaran kegaitan keterampilan jurnalistik dasar dalam rangka membangun aktivitas jurnalistik yang sehat di lingkunagan sekolah. Ruang jurnalisme yang sehat diharapkan akan menjadi sarana bagi seluruh komponen sekolah, terutama siswa, dalam menyampaikan aspirasi. Kesimpulan yang dapat ditarik dari kegiatan ini adalah bahwa penting mengenalkan dunia jurnalistik sejak dini, terutama pada pelajar SMK/Sederajat yang notabene sudah mendekati usia dewasa. Pentingnya pemahaman jurnalistik bagi pelajar dapat membangun generasi yang tidak latah dengan pemberitaan di media. Beranjak dari kesimpulan yang didapat, yang menjadi rekomendasi utama ialah perlunya membangun budaya jurnalistik di lingkungan sekolah. Jurnalisme sekolah, selain sebagai penyedia informasi, dapat juga menjadi media bagi siswa untuk menyampaikan aspirasinya
PENCEGAHAN KENDALA DALAM TRANSFER PRODUCED WATER NILAM KE BADAK DENGAN SIMULASI & ANALISIS PENGGANTIAN PIPA 12” HDPE MENJADI PIPA 6” CS
No full textProduced water is the main liquid waste in the oil and gas production process that must be safely transferred to the processing facility. The current produced water transfer system in the Nilam Field uses 12” HDPE pipes, but this material has limitations in terms of high pressure and potential deformation. This study aims to analyze the technical feasibility of replacing 12” HDPE pipes with 6” carbon steel (CS) pipes through hydraulic simulations using Aspen HYSYS and further calculations using Microsoft Excel. The main variables analyzed include pressure drop, flow velocity, and the maximum limit of the replacement pipe length that is still operationally safe. The simulation results show that the pressure drop of 6” pipes is greater than that of 12” pipes, so an evaluation of the maximum length of the pipe that can be replaced is necessary. The analysis results show that 12” pipes can only be replaced with 6” CS pipes with a maximum length of 2,025.97 meters, before the pressure drop and pressure surge exceed the operational safety limit. Thus, pipe replacement can only be done partially and it is not recommended to replace the entire existing pipeline

PERANCANGAN AKSESORI FESYEN SEBAGAI SUVENIR KHAS TEMANGGUNG BERBAHAN SISA PRODUKSI DAUN TEMBAKAU
Full text linkTemanggung Regency is known as a tobacco production center, yet it currently lacks a signature souvenir product that utilizes the uniqueness of local materials such as tobacco leaf production waste. These discarded leaves, which are not selected for cigarette manufacturing, are abundant and can cause environmental pollution if left unmanaged. This project aims to design fashion accessories such as a card holder, clutch, and mini bag as distinctive souvenirs of Temanggung by using laminated tobacco leaf waste, while representing local identity and cultural values. The design challenge focuses on how to create products that are functional, aesthetic, and reflective of Temanggung’s uniqueness, including the Wiwitan Tembakau tradition. The method used is Material Driven Design (MDD), involving exploration of material characteristics, technical experimentation, and product development through model studies and user evaluations. The results show that laminated tobacco leaves offer sufficient flexibility and strength to substitute conventional leather for small-scale products. Material thinning and reinforcement are essential to achieve neat construction and user comfort. The final products not only fulfill practical and aesthetic needs but also communicate local cultural narratives through their visual and philosophical design elements. This project demonstrates that tobacco leaf waste can serve as a sustainable alternative material that strengthens regional identity and opens opportunities for developing a local wisdom-based creative economy
