Abstract

The necessary of technology at this time resulted the necessary of energy resources will increasing, and it also result the scarcity of energy resources. One of the energy resources that is still used as a major energy resource is oil and gas. To overcome these problems, exploration activities at this time needs to be further improved. In the field of exploration, one of the most important things to know is reservoir. Reservoir quality is important for us to know so that we can determine whether an area has hydrocarbon potential to be developed or not. The main parameters of reservoir quality are porosity and permeability.In this study discussed the analysis of provenance, diagenetic and depositional environment of the sandstone reservoir of Talang Akar Formation, North West Java Basin and from the results of the analysis will be associated with the effect on reservoir quality. To determine the reservoir quality based on these parameters, can be done by several methods such as petrographic, cores, SEM and XRD analysis. From the analysis that has been done can be seen that the provenance of Talang Akar sandstone is Granite. So it can be seen that the Talang Akar sandstone which the provenance is Granite has good reservoir quality, with porosity values ranging from 19.04% to 24.28% and permeability ranging between 30-674 mD or belonging to the class good - very good (Koesoemadinata, 1980). Then the diagenetic process that occurs is compaction, cementation, replacement and dissolution. The process of compaction, cementation and replacement leads to reduced rock porosity values ranging from 2.25 to 11.5%, while the dissolution process resulting in increased rock porosity is about 1.5 - 2%. The depositional environment of the Talang Akar Sandstone is Upper Delta front. Rock facies in the upper delta front has good reservoir quality, with porosity values range from 19.04% to 24.28% and permeability range between 30-674 mD or belonging to the class is good - very good (Koesoemadinata, 1980).

Abstract

Dari hasil evaluasi simpang tak bersinyal yang terletak pada Jalan Raya Wonorejo, Kabupaten Pasuruan didapatkan hasil nilai tundaan D = 18 det/smp dan level of service = C, dengan jumlah keseluruhan komponen BOK Rp. 11.495/km, yang artinya kurang memenuhi standar PKJI 2023. Penelitian ini menganalisis alternatif pelebaran simpang sebesar 1 meter untuk mengurangi kepadatan yang terjadi. Data-data yang digunakan meliputi data primer dan sekunder. Data primer meliputi data geometrik jalan, data hambatan samping, data survei arus lalu lintas dan data kecepatan kendaraan. Sedangkan data sekunder diantaranya data jumlah pendudukan dan lokasi penelitian. Data-data tersebut kemudian diolah menggunakan PKJI 2023. Dari hasil analisis alternatif penanganan didapatkan nilai tundaan D = 15 det/smp, level of service = B, dan jumlah keseluruhan komponen BOK Rp. 4.844/km

Abstract

Salah satu metode teknik pembuatan benang dari bahan baku berupa serat tekstil yang banyak digunakan adalah ring-spinning karena efisiensi produksi yang stabil dan kemampuannya menghasilkan berbagai jenis benang. Kualitas benang sangat dipengaruhi oleh pengaturan parameter dan komponen pada mesin ring frame, termasuk penggunaan pin spacer di area drafting. Penelitian ini bertujuan untuk mengkaji pengaruh penggunaan pin spacer terhadap kualitas benang kapas Ne 30 yang diproduksi dengan mesin compact ring-spinning. Pada penelitian ini telah diamati kualitas benang yang dihasilkan dari sistem pemintalan ring frame yang menggunakan spacer dan tanpa menggunakan spacer. Hasil menunjukan bahwa penggunaan spacer memiliki pengaruh pada parameter kualitas ketidakrataan (unevenness) benang, kekuatan benang (strength & tenacity) dan jumlah bulu pada benang (hairiness), meskipun Imperfection index (IPI) tidak terpengaruh oleh penggunaan spacer pada mesin. Penelitian ini telah menunjukan bahwa terdapat dampak signifikan dari penggunaan spacer terhadap kualitas benang.

Abstract

This research focused on assessing how the interaction between planting media composition and vesicular arbuscular mycorrhizal (VAM) biofertilizer influences the growth of Arabica coffee seedlings. The formulated hypothesis helped direct the study toward identifying the most favorable conditions for seedling development. The experimental design employed was a factorial randomized block design (RBD), comprising 16 different treatment combinations, each repeated twice. The first treatment variable (Factor P) involved different mixtures of topsoil, rice husk, and compost: P0 = 100% topsoil, P1 = 60% topsoil + 20% rice husk + 20% compost, P2 = 60% topsoil + 40% rice husk, and P3 = 60% topsoil + 40% compost. The second variable (Factor M) concerned the application of VAM biofertilizer in doses of 0 g (M0), 0.5 g (M1), 1 g (M2), and 1.5 g (M3). Statistical analysis showed that the interaction between media composition and VAM biofertilizer significantly influenced all growth indicators measured in the Arabica coffee seedlings.

Abstract

In the 6th assessment report published by the IPCC (Intergovernmental Panel on Climate Change), it is stated that the impact of climate change will be felt on the settlements and infrastructure of people living in coastal areas. The magnitude of this potential impact has encouraged the Anambas Islands Regional Government to include this impact in the Anambas Islands District Medium Term Development Plan for 2021-2026. Of course, synergy is needed in handling these impacts by involving all stakeholders, including oil and gas companies operating in this area. This study aims to determine the impact of climate change and the forms of community adaptation, as well as community perceptions of the contribution of oil and gas companies through the CSR change program in order to help mitigate climate impacts and also increase the adaptability of the community. Data was collected from all stakeholders as well as beneficiaries of the company's CSR program, by conducting in-depth interviews, observations, and also using a questionnaire. For the general public, climate change has begun to be felt with extreme weather conditions that often cause disasters, as well as decreased catches of fishermen in coastal areas. In fact, in certain seasons it will affect the smooth transportation of sea people, so that it can affect people's daily activities. Regarding the CSR program that has been carried out by oil and gas companies, the community considers this program very important for them, but further efforts still need to be made in order to meet their expectations, including increasing income.
