Abstract

Kenyamanan berjalan kaki adalah salah satu faktor penentu dalam keinginan dan motivasi berjalan kaki, terutama di area kampus. Pembangunan infrastruktur jalan di zona pendidikan pada umumnya tidak dilengkapi dengan pembangunan jalur pedestrian yang menyenangkan karena area hijau yang ditebang sehingga membuat cuaca semakin panas. Penelitian ini dilakukan untuk mengeksplorasi faktor-faktor pengalaman sensori yang paling mempengaruhi kenyamanan berjalan kaki menuju kampus, terutama di jalur menuju UIN Mataram Kampus 1 yang terletak di Jalan Pendidikan Kota Mataram. Pengumpulan data dilakukan dalam dua tahap, yaitu observasi dan pemetaan langsung di lapangan dan pengumpulan data melalui kuesioner online. Data observasi akan diolah melalui pemetaan data sensori, sementara data kuesioner diolah dengan one-way ANOVA. Hasil studi menunjukkan kenyamanan visual berkaitan dengan elemen fisik dan kenyamanan termal berkaitan dengan perubahan waktu kunjungan menjadi penentu keinginan berjalan kaki. Studi ini menggarisbawahi pentingnya aspek manusia terutama dalam kenyamanan sensori dalam perencanaan kota agar pengembangan kota berkelanjutan. Implikasi hasil penelitian menjadi gagasan dan acuan dalam perancangan dan perencanaan infrastruktur jalur pedestrian kota khususnya di area zona pendidikan.

Abstract

Teh merupakan salah satu tanaman perkebunan bernilai ekonomis dengan umur produktif yang sangat dipengaruhi oleh teknik budidaya. Pengelolaan pemeliharaan berperan penting dalam mempertahankan dan meningkatkan produksi pucuk teh. Penelitian ini bertujuan menganalisis pengelolaan pemangkasan untuk peningkatan produksi teh di kebun Pagilaran. Hasil pengamatan menunjukkan bahwa tanaman teh pada blok yang diamati telah memenuhi beberapa syarat dasar pemangkasan, seperti tinggi tanaman (112.63 cm) dan penurunan produktivitas (persentase pucuk burung 62%-80%). Umur pangkas kedua blok pengamatan belum mencapai standar (48 bulan), tetapi sudah mendekati (44-46 bulan). Tinggi pangkasan tanaman teh belum sesuai dengan standar kebun (40-45 cm). Kerusakan cabang yang terjadi berkisar 10%-14%. Berdasarkan uji t-student, lama kerja dan usia pemangkas berpengaruh nyata terhadap keterampilan tenaga pangkas. Pengawasan lebih lanjut dari pembimbing (mandor) sangat diperlukan untuk menghindari timbulnya kesalahan di lapangan. Luas areal pangkas yang dilakukan pada tahun 2019 melebihi luas areal yang disarankan, yaitu 25%. Tenaga pangkas yang digunakan telah memenuhi jumlah pemangkas standar dan kapasitas pemangkas sudah mencapai target yang ditetapkan. Pertumbuhan tunas sangat penting diperhatikan untuk menghitung gilir petik. Laju pertumbuhan tunas paling cepat terjadi pada cabang kecil dengan jenis bahan tanam KIARA. Tanaman yang berasal dari biji/seedling mengalami laju pertumbuhan paling lambat dibandingkan jenis bahan tanam lainnya. Kata kunci: kerusakan cabang, klon, laju pertumbuhan, pemangkasan, pucuk burung

Abstract

This study aims to enhance fifth-grade students’ ability to identify figures of speech through the implementation of the Problem-Based Learning (PBL) model supported by “clothes hanger” media. The media were designed to facilitate contextual learning through visual and kinesthetic engagement, helping students grasp abstract literary concepts more concretely and enjoyably. The research employed a quasi-experimental design with a one-group pretest–posttest approach involving 30 fifth-grade students from SD Negeri 3 Tegowanu Wetan. Data were collected using a figure-of-speech identification test and analyzed through descriptive statistics and paired t-tests. The findings revealed a significant improvement in students’ mean scores from 72.10 (pretest) to 79.80 (posttest), with a mean gain of 7.70 points (t(29) = 4.26, p = 0.0002) and a moderate-to-strong effect size (Cohen’s d = 0.78). These results indicate that implementing PBL with simple yet contextual learning media effectively enhances students’ mastery of figurative language while fostering critical thinking, creativity, and collaboration skills.

Abstract

Rhamnolipid biosurfactants derived from microbial sources have gain substantial interest as environmentally sustainable alternatives to synthetic surfactants, particularly in the realm of Microbial Enhanced Oil Recovery (MEOR). Their biodegradability, low toxicity, and effectiveness under extreme conditions make them ideal candidates for improving oil displacement in reservoir. However, the presence of divalent ions, specifically calcium (Ca²⁺) and magnesium (Mg²⁺), which are abundant in reservoir brine, can significantly affect the performance of these biosurfactants. This research investigates the influence of Ca²⁺ and Mg²⁺ ions on the phase behavior, stability, and interfacial properties of rhamnolipid-based microemulsion systems, which play a critical role in MEOR processes. A series of experiments was conducted to analyze the impact of varying concentrations of Ca²⁺ and Mg²⁺ ions on rhamnolipid microemulsions. The study evaluated phase transitions, stability, and microstructural characteristics of emulsions using a spinning drop tensiometer to measure interfacial tension (IFT) and rheological analysis to determine viscosity. The results demonstrate that both Ca²⁺ and Mg²⁺ ions influence the optimal salinity conditions required for microemulsion stability, with their presence causing shifts in the phase boundaries. Notably, Ca²⁺ ions exert a more pronounced effect on phase stability compared to Mg²⁺, leading to increased IFT and viscosity at higher concentrations. These findings further elucidates the crucial role of divalent ions in governing the stability and functionality of biosurfactant systems under reservoir conditions and highlight the importance of controlling ion concentrations to achieve efficient MEOR applications. Overall, this research provide valuable insight for optimizing the formulation of rhamnolipid-based systems to enhance oil recovery performance while mitigating the adverse effects of high divalent ion content in brine. The research contributes to ongoing efforts to improve biosurfactant efficacy, offering a pathway toward refining MEOR strategies and advancing sustainable oil recovery technologies.

Abstract

DLN-11 well was temporarily shut-in due to excessive water production, which became the main issue causing a decline in daily oil production. Therefore, this study conducted an integrated analysis to determine the cause of excessive water production, so that appropriate mitigation measures could be implemented, as well as to formulate a well reactivation strategy aimed at optimizing oil production. The methodology in this study was carried out in an integrated manner through technical and economic evaluations. The technical analysis began with the application of the Chan diagnostic plot as an initial mitigation step, followed by the evaluation of data logging, core analysis data, and production data as advanced mitigation steps to obtain appropriate solutions for addressing production-related issues. In addition, an economic analysis was conducted as a basis for decision-making within a risk management framework. Based on the results of the integrated analysis between the Chan diagnostic plot method and cement evaluation data from Cement Bond Log (CBL), Variable Density Log (VDL) dan Ultra Sonic Imaging Tool (USIT), the high water cut in DLN-11 well, as a reactivation candidate, was caused by water channeling due to the presence of free pipe conditions, where the cement did not properly isolate the annulus between the casing and the formation. To overcome this issue, remedial cementing was carried out to improve the quality of cement bonding. Furthermore, based on the evaluation results of the C/O Log, DLN-11 well still owns five potential oil-bearing zones that can be produced. The reactivation strategy was implemented by opening the interval of 7927-7942 ftMD, resulting in a production rate of 549 BOPD with a water cut of 82%. The economic analysis results indicate that DLN-11 well yields an NPV of 1,256,000 US$, an IRR of 247.5%, and a Pay Out Time (POT) of 3 months and 16 days. Therefore, from both technical and economic perspectives, the implemented reactivation strategy for DLN-11 well has proven to increase oil production and generate positive economic indicators.

Abstract

This study aims to address low learning motivation and the lack of variety in teaching resources for poetry material at SMA Negeri 1 Sandai through the development of flipbook-based learning media. This study used the Research and Development (R&D) method with the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). The research subjects included six expert validators, one Indonesian language teacher, and 28 grade XI students as product users. Data collection was conducted using interviews and questionnaires, then analyzed descriptively and quantitatively. The results showed that the developed flipbook product obtained a validity score of 93.66% (very valid) and a practicality score of 93.79% (very practical). Furthermore, the product effectiveness test validated a significant increase in students' cognitive learning outcomes with an average Normalized Gain (N-Gain) score of 0.62 (moderate category). These empirical findings indicate that the integration of audio-visual elements in flipbooks is effective in visualizing abstract poetry concepts into concrete ones and maintaining student learning motivation. The implications of this study recommend the use of interactive media as an alternative solution for literature learning in the digital era.

Abstract

One of the consequences of deforestation is the spread of critical land both inside and outside the forest area. Agroforestry or intercropping is developed to provide benefits and improve welfare for the community, and to optimize the results of a form of sustainable land use to ensure and improve food needs. Eucalyptus is one type of plant that is suitable for forest land rehabilitation because of its ability to live on marginal lands. The purpose of the study was to assess the feasibility of eucalyptus oil business and formulate business sustainability development from seven aspects/feasibility parameters, which are namely: (1) legal aspects, (2) social, economic and cultural aspects, (3) market aspects, (4) management and human resources, (5) risk management aspects, (6) technical aspects, and (7) financial aspects. Meanwhile, to find out whether the eucalyptus business activity as a whole can be sustainable, and its development model, a sustainability analysis was carried out using the cobweb (Amoeba) method. Within the framework of sustainability, eucalyptus concessions must make changes and innovations (Estimated business feasibility on a planting area of 5,200 ha obtained a Net Present Value (NPV) of Rp. 950,734,956,062, - with a discounted interest rate of 12% shows that the eucalyptus oil industry will get a net profit of Rp 7,076,409,779,281, - BC Ratio of 12.56, Interest Rate of Return (IRR) of 55%, Payback Period in the 5th year 4 months shows that in a period of 5 years and 4 months from the investment can be returned from business revenues. The results showed that the seven aspects/parameters were declared feasible and continued with a sustainability analysis and concluded that the eucalyptus oil concession was declared sustainable.
