A relevância dos serviços ecossistêmicos no cenário urbano
Authors: Schonardie Elenise Felzke , Strada Juliane Strada 
Published: July 2023

O artigo pondera a importância dos serviços ecossistêmicos e de suas funções para os o bem-estar humano. O recorte do problema visa a análise utilitarista dada aos recursos naturais, pois são neles que se encontram os stocks de matéria prima para sobrevivência humana. Mas é preciso considerar a finitude da sua capacidade, e que os ganhos alcançados na qualidade de vida, até hoje, se deram ao custo de uma grande degradação dos serviços ecossistêmicos. Assim, objetiva-se demonstrar a funções dos serviços ecossistêmicos como fatores que contribuem para o bem-estar humano. E uma vez que a maioria da população está concentrada em centros urbanos, também objetiva deixar demonstrado a relevâncias destes serviços para formação de cidades sustentáveis. A abordagem metodológica é qualitativa, permitindo o tipo de pesquisa exploratória e descritiva por meio de procedimentos bibliográficos e documentais, fundamentada no método estrutural. Finaliza confirmando a relevância das relações entre os serviços ecossistêmicos e o bem-estar humano, sendo essas complexas e não lineares, o que requer uma nova postura por parte dos gestores públicos e dos demais setores que foram o conjunto social, para pensar, compreender e avaliar a importância da implementação dos serviços ecossistêmicos nos territórios urbanos.

La imaginación poética de Olga Costa y José Chávez Morado en Cuautla: el agua, el nacimiento de la ciudad y las sirenas
Authors: Comisarenco Mirkin Dina 
Published: July 2023

En el presente trabajo se analiza el ciclo mural de Olga Costa y José Chávez Morado, realizado en el Balneario Agua Hedionda de Cuautla, Morelos en 1952, obra que permite observar algunas de las diferencias temáticas y estilísticas de cada uno de los miembros de la pareja de artistas de forma paradigmática. Apoyándome en algunos conceptos de Gaston Bachelard en su obra clásica El agua y los sueños: ensayo sobre la imaginación de la materia (1942), en el texto interpreto los imaginarios de los artistas en sus representaciones sobre el agua. Considerando sus visiones individuales en torno a la conceptualización y a la ensoñación del motivo del agua, se concluye que, para conocer el movimiento muralista mexicano en todo su alcance, es necesario integrar al muralismo femenino que complementa y enriquece al fenómeno cultural del movimiento creado originalmente con la intención de democratizar el arte.

Abstract. Workplace telepressure is defined as the preoccupation and urge to immediately respond to work-related asynchronous messages in the form of ICT during private hours and working hours, (Barber et al., 2019). This demand to promptly respond to messages can hinder resource recovery and lead to poor well-being, such as burnout (Maslach & Leiter, 2008; Sonnentag & Fritz, 2015). Burnout is a feeling of emotional exhaustion, physical exhaustion, and cognitive fatigue resulting from the gradual depletion of an individual's intrinsic energy sources that occur over time due to work (Shirom 2005). This study aims to determine whether or not Workplace Telepressure contributes to Burnout, as well as to see how big this contribution is. This research is a quantitative research with a causality correlation approach. Using non-probability sampling technique with accidental sampling technique (convenience sampling). Respondents to this study consisted of 30 resident doctors who were pursuing a Specialist Medical Education Program at the Department of Physical Medicine and Rehabilitation, University of Padjadjaran. Using the Workplace Telepressure measurement tool from Barber and Santuzzi (2015) which has been adapted by Parahyanti and Hutama (2022), and the Shirom-Melamed Burnout Measure (SMBM) (2018) which has been adapted by researchers. The results of this study indicate that Workplace telepressure contributes significantly to burnout by 15.2%.
Abstrak. Workplace Telepressure didefinisikan sebagai preokupasi dan dorongan untuk segera menanggapi pesan asinkronus berbentuk Teknologi Informasi Komunikasi terkait pekerjaan selama jam pribadi dan jam kerja, (Barber et al., 2019).

Authors: Tampubolon Arjuna 
Published: July 2023

Abstract. Problems at the research location indicate that production has not been achieved, causing high mining operational costs. The aim of this research is to increase production targets for operational costs incurred using the rupiah exchange rate with the assumption that 1$ = Rp. 14,300. The research method uses linear programming and the bunching effect. Data collection was carried by calculating the number of available mining operational tools and cycle time data is taken as much as 270 data on 3 mining fleets. The actual productivity generated is 328.49 BCM/hour with an actual production cost of $2.35 USD/BCM with a predetermined target of 500 BCM/hour. The results of the actual conditions need to be corrected by optimizing the number of conveyances to be used using the POM for Windows application, namely the number of conveyances used is 10 units with a production of 520.22 BCM/hour and a production cost of $1.6 USD/BCM. The results showed that the use of 10 units of means of transportation resulted in optimal production with minimum costs compared to the use of 9 units of means of transportation. The loss of time experienced by the transportation equipment due to the bunching effect is 7 hours/month due to differences in engine power on the transportation equipment, different operator skills, undulations street and puddles on the road surface, non-ideal mine road geometry.
Abstrak. Permasalahan di lokasi penelitian menunjukkan belum tercapainya produksi, sehingga menyebabkan tingginya biaya operasional penambangan. Tujuan dilakukan penelitian guna meningkatkan target produksi terhadap biaya operasional yang dikeluarkan menggunakan nilai tukar rupiah dengan asumsi 1$ = Rp 14.300. Metode penelitian menggunakan program linear dan bunching effect. Pengambilan data dilakukan dengan menghitung jumlah alat operasional penambangan yang tersedia serta data cycle time diambil sebanyak 270 data pada 3 fleet penambangan. Produktivitas aktual yang dihasilkan sebesar 328,49 BCM/jam dengan biaya produksi aktual sebesar $2,35 USD/BCM dengan target yang sudah ditetapkan sebesar 500 BCM/jam. Hasil kondisi aktual perlu dilakukan tindakan perbaikan dengan melakukan optimasi jumlah alat angkut yang akan dipakai menggunakan aplikasi POM for Windows yaitu jumlah alat angkut yang dipakai sebanyak 10 unit dengan produksi sebesar 520,22 BCM/jam dan biaya produksi sebesar $1,6 USD/BCM. Hasil penelitian menunjukkan bahwa pemakaian 10 unit alat angkut menghasilkan produksi yang optimal dengan biaya yang minimum dibandingkan dengan pemakaian 9 unit alat angkut. Hilangnya waktu yang dialami alat angkut akibat adanya bunching effect sebesar 7 jam/bulan karena terdapat perbedaan daya mesin pada alat angkut, keterampilan operator yang berbeda-beda, terdapatnya undulasi jalan, genangan air pada permukaan jalan dan geometri jalan tambang yang tidak ideal.
