Abstract

Synthesis of Zr-ZA catalystused as catalyst for esterification reaction of glycerol with acetic acid anhydrous has been done. Catalysts are characterized using an infrared spectrophotometer, X-ray diffraction, and measurement of surface acidity, while reaction products are characterized using a gas chromatography-mass spectrometer. Effect of catalyst acidity, reaction time and re-addition of acetic acid anhydrous studied by glycerol conversion and selectivity value of triacetin were yielded. Infra-red spectrophotometer and X-ray diffraction analysis of the catalyst showed that the synthesized catalyst was zirconium zeolite (Zr-ZA), while esterification analysis using a gas chromatography-mass spectrometer showed a triacetin product.

Abstract

Peternak ruminansia merupakan mata pencaharian dari lima belas persen warga desa Batokan Kecamatan Ngantru, Kabupaten Tulungagung. Ketersediaan pakan hijau, akses akan informasi penyakit ruminansia, pengetahuan pakan alternatif, akses vaksin, lahan penggembalaan, pemanfaatan kotoran merupakan beberapa kesulitan yang dihadapi peternak Sebagai salah satu inti keberhasilan pembibitan hingga penggemukan ruminansia, pakan hijau mutlak harus dipastikan ketersediaannnya. Bagi peternak dengan lahan terbatas atau pemodal kecil, hal tersebut akan sulit untuk dilakukan sehingga dibutuhkan alternatif hijauan ruminansia. Ole karena itu, pelatihan pembuatan pakan alternatif diperlukan guna mematikan ketersediaan pakan. Pada pelatihan ini menggunakan rumput gajah sebagai bahan baku utama pakan alternatif digabungkan dengan bahan lain. Pembuatan pakan ternak menggunakan teknik fermentasi. Berdasarkan pelatihan yang telah dilakukan dapat dinyatakan berhasil dilihat dari tingkat kehadiran, keaktifan dan hasil proses fermentasi. Selain itu hasil survey menunjukkan semua kriteria penilaian: ketepatan tujuan, sasaran, penyampaian dan harapan akan keberlangsungan pelatihan memiliki nilai lebih dari 4 (baik). [Ruminant farming is the livelihood of fifteen percent of the residents of Batokan village, Ngantru District, Tulungagung Regency. Availability of green feed, access to information on ruminant diseases, knowledge of alternative feed, access to vaccines, grazing land, use of manure are some of the difficulties faced by the breeders. As one of the core successes of breeding and fattening ruminants, availability of green feed must be ensured. For breeders with limited land or small capital, there will be difficult for availability of green feed. Therefore, training in making alternative feed is needed for feed availability. This training uses elephant grass as the main raw material for alternative feed combined with other ingredients. Making animal feed using fermentation technique. Based on the training that been carried out, can be concluded successful based on the level of attendance, activeness and result of the fermentation process.]

Abstract

Indonesia, situated within the Pacific Ring of Fire, exhibits a unique combination of dynamic tectonic plates and active volcanoes, rendering it susceptible to various seismic activities, ranging from minor tremors to large-scale earthquakes (megathrust). Volcanic eruptions, a prevalent natural disaster in Indonesia, pose significant threats due to the presence of over 130 active volcanoes, with 129 concentrated on Java Island alone. Among these, Mount Merapi stands out as the most active and perilous, situated 30 kilometers north of Yogyakarta City, spanning the administrative boundaries of Yogyakarta Special Region and Central Java. Educational institutions, particularly schools, serve as vital hubs equipped with resources and infrastructure that demand meticulous preparation for potential disasters. This research endeavors to assess the level of school preparedness in the face of disasters, with a specific focus on volcanic eruptions. Through data processing and analysis, it is discerned that Y Primary School in Girikerto village exhibits the highest average preparedness score across five criteria: disaster management plan, community action plan, rehabilitation efforts, early warning system, and competency (89.66%). This is followed by X Primary School (82.39%) and Z Primary School (22.61%). In a broader context, the study reveals that 17.4% of respondents exhibit low preparedness, 4.35% fall within the medium preparedness category, while 34.8% and 43.5% demonstrate high and very high preparedness respectively.

Abstract

Bamboo is included in the classification of grasses, but because of its large size compared to other types of grass, bamboo is also called "giant grass". Bamboo has the ability to grow fast, reaching 30-100 cm per day. The target of this community service is the empowerment of the Daerah Istimewa Yogyakarta (DIY) Search and Rescue (SAR) Team in Wonokerto to become a transfer agent for laminated bamboo technology through the training provided. The approach used in this community service is based on research that has been carried out in universities (research-based community development) by involving potential communities as social agents and potential assets (assessed-based community development) in the community to support Mount Merapi as a National Strategic Area (KSN). In training implementation, the participants showed high contribution in providing training material, attendance, and involvement. Based on the training survey on bamboo laminate technology, 80.59\% of respondents know the identification material, stage of preparation material, identification of connection mixture, identification of lamination stage, and quality check of laminated bamboo lumbar. The proposed training or assistance for sustainability community services are marketing, business planning, product design, and quality products.

Abstract

This Study evaluated mental workload of Rapid Response Team ((RRT) Regional Disaster Management Agency in Special Region of Yogyakarta as funeral team along COVID-19 pandemic. Mental workload is formed due to differences between individual abilities and performance demands of a task within a certain time. NASA TLX is the most widely used mental workload measurement, capable of being used in several levels of workload and sensitive to low workloads. The Rapid Response Team is a team to ensure that the disaster management process carried out quickly, accurately, skilled personnel to back up the medical team who continue to work hard so that the handling of the pandemic virus is better, and the virus does not spread. In this study, the subject of research is the funeral team of Rapid Response Team ((RRT) Regional Disaster Management Agency in Special Region of Yogyakarta Indonesia. Sampling data was collected online and offline using the Goggle Form in the range March-April 2021. There are 28 team members of the RRT who filled out the questionnaire. Workload assessment using the NASA-TLX and OWL methods falls within the range of medium (45.58458; 0.610535), high (74.73789; 0.739889), and very high (87.7969; 0.879976), with an average workload value of high (75.9935; 0.748672). Based on statistical tests using paired t-tests and one-way ANOVA, both methods are declared to be equivalent. The dimension that predominantly contributes to workload according to the NASA TLX method is Effort, followed by Mental Demands. Meanwhile, the factor that predominantly forms the workload according to the OWL method is S2 (Environmental Workloads, sub-factors: improper temperature, chemical exposure), followed by S3 (Body Motion and Postural Workloads, sub-factors: stooping, standing). The research findings offer manual guidance for workload identification, particularly utilizing OWL, serving as the foundation for workload assessment for teams involved in COVID-19, particularly in Indonesia. Additionally, this study also demonstrates that the OWL method possesses the same level of reliability as the NASA-TLX method.
