Abstract

The coast of Ketingan Sidoarjo is a fairly dynamic area, where the lives of fishermen depend on fishing. Ecosystem changes that occur in the coastal area of Ketingan Sidoarjo greatly affect the fishing effort, where one of the parameters that can be observed is the distribution of chlorophyll content from the water bodies on the coast. The purpose of this research is to analyze and map the distribution of chlorophyll content in the coastal area of Ketingan, Sidoarjo. This is based on the fact that researchers have not done much research on chlorophyll using 2-channel Terra Modis satellite imagery, where the best response is on Channel 3 = Rrs_678/Rrs_555, the best model obtained is the 2nd order Polynomial Algorithm Model y = 1.2446 x2 – 1.725 x + 1.0987 with a degree of determination R2= 0.3826.

Abstract

Railways in Indonesia still show problems, such as time delays. To make train services in Indonesia better, government efforts are needed, one of which is the development of new infrastructure, such as the construction of a double-track train such as Sepanjang to Mojokerto segment. So it is necessary to analyze the level of service both in existing conditions and after construction. The analysis was carried out in two conditions, namely, full single track and full double track. For full double-track reference, a simulation is carried out with an auxiliary program, namely the Railway Operation Simulator (ROS). By entering data in the form of station layouts, train facilities, and signaling systems and blocks. Based on the analysis results, it shows that the double track in the Sepanjang-Mojokerto segment affects the level of service. The prediction of service levels for the Sepanjang-Mojokerto segment shows that three road plots have LoS A. So, overall, with the construction of the double track, this segment is operating below capacity and has low traffic.

Abstract

Kabupaten Sidoarjo merupakan salah satu kota padat penduduk sekitar 2,3 juta jiwa, hal itu tentunya mempengaruhi peningkatan jumlah kendaraan bermotor, sehingga menyebabkan bertambahnya tingkat kebisingan lalu lintas. Dampak dari bertambahnya tingkat kebisingan tentunya menimbulkan ketidaknyamanan bagi pengguna jalan, kerusakan lingkungan, dan kesehatan masyarakat. Tujuan dari penelitian ini adalah untuk mengetahui tingkat kebisingan yang diterima oleh 3 rumah sakit yaitu RSUD Sidoarjo, RSI Siti Hajar Sidoarjo, RS Delta Surya akibat lalu lintas jalan raya di depan rumah sakit. Sistem Informasi Geografis sebagai alat bantu diharapkan dapat memberikan informasi berupa pemetaan tingkat kebisingan. Penelitian ini dilakukan pada jam sibuk yaitu pukul 07.00 – 09.00 di pagi hari, dan 16.00 – 18.00 di sore hari. Dari penelitan tersebut didapatkan hasil kebisingan tertinggi pada pagi hari yaitu sebesar 78,60 dBA di RSUD Sidoarjo di Jalan Mojopahit (Titik 1), sedangkan pada sore hari didapatkan hasil kebisingan tertinggi sebesar 78,49 dBA di Jalan KH Mukmin (Titik 3). Untuk hasil perhitungan menggunakan metode regresi linear didapatkan nilai R2 tertinggi sebesar 0,911 di Jalan Raden Patah (Titik 15) dengan nilai korelasi positif sangat kuat sebesar 0,8352 untuk SM. Sehingga dapat disimpulkan bahwa semakin banyak volume kendaraan maka tingkat kebisingan yang diterima juga akan semakin meningkat.

Abstract

The "Baru Sadar" farmer group in Gerantung village, Central Lombok, NTB, has received training in organic farming, but still has doubts about its effectiveness, especially in terms of crop yields. This uncertainty is related to the productivity of organic farming compared to conventional methods, so they have not fully converted to an organic farming system. Extension was used to improve their understanding of organic practices, increase knowledge, identify problems and offer solutions to increase farmers' confidence in the results of the organic system. The methods used included lectures, question and answer sessions and in-depth discussions with group leaders and extension officers. Extension materials covered the importance of organic farming, soil management, organic fertiliser and the business of organic products such as certification and marketing. The farmer group members were enthusiastic and raised several issues during the discussion, such as slow plant growth with organic fertiliser, low productivity and marketing constraints. Continued extension support, financial assistance, demonstration plots and marketing facilitation are needed to encourage farmers to switch to more sustainable practices so that more farmers are motivated to adopt organic farming systems.

Abstract

The rapid development of technology can have many positive and negative influences on human life, especially in the field of education. This is shown by the presence of gadgets. Gadgets are technology that can be accessed by all groups, from children, teenagers, adults and even the elderly. Excessive use of gadgets can cause addiction and even have a negative impact on children's education. Where children prefer to spend their time playing with gadgets and often neglect their education. Children tend to focus more on gadgets than reading a book, this can reduce children's interest in reading. Thus, the importance of children's awareness of their interest in reading really needs to be emphasized so that children's knowledge increases. The aim of this research is to determine the impact of gadgets on the degradation of elementary school students' reading interest.

Abstract

Indonesia, sebagai negara berkembang, mengalami banyak pengembangan dan pembangunan di sektor infrastruktur, termasuk gedung bertingkat. Di era sekarang ini perkembangan pembangunan gedung sangatlah pesat, faktor utama nya adalah keterbatasan lahan yang menjadikan perkembangan pembangunan gedung bertingkat ke arah vertikal. Dalam proses ini, aspek pengelolaan limbah menjadi sangat penting untuk meminimalisir dampak lingkungan. Sistem penanganan limbah yang komprehensif diperlukan untuk mengelola material sisa yang dihasilkan dari proses konstruksi melalui pengurangan, pemakaian kembali dan mendaur ulang. Pendekatan green construction dapat membantu mengurangi limbah dan dampak negatif terhadap lingkungan. Penelitian ini mengidentifikasi konsep green construction pada tahap konstruksi dengan menggunakan metode identifikasi indikator dari GBCI. Data dikumpulkan melalui wawancara, observasi lapangan, dan analisis dokumen. Hasil evaluasi kategori polutan kimia dan polusi dari aktivitas konstruksi pembangunan Rumah Sakit ‘Aisyiyah Bojonegoro menunjukkan bahwa kedua kategori tersebut memenuhi tolok ukur Greenship dengan prosentase sebesar 100%. Maka dari itu dengan perencanaan dan pelaksanaan manajemen limbah yang baik, serta dukungan dari setiap tim yang terlibat, dampak negatif terhadap lingkungan dapat diminimalkan dan efisiensi sumber daya dapat ditingkatkan.

Abstract

The relocation of the grave of Junaidiyah tharȋqah’s leader, Shaikh Muhammad Qurthubi, in Palangka Raya is unique. It was done without dismantling the old grave or moving his body. This unusual step was based on mystical messages from the shaikh’s spirit to his chosen students. This research explores why this action was taken and how this mystical doctrine became the community's shared belief. It is a qualitative study, and data were collected through interviews and observation using a phenomenological approach. The research findings are analyzed using theories of group communication, ritual communication, and the psychology of communication. The results show that Junaidiyah tharȋqah is a primary group with norms and doctrines that members must follow, determining their communication patterns. These patterns tend to be one-way in matters of teachings and spirituality and multidirectional in administrative and institutional matters. Interpersonal communication is intimate and solid. The research implies that the Junaidiyah tharȋqah's mystical doctrines deeply influence their members' communication patterns, fostering unwavering spiritual loyalty and shaping unique interpersonal and group communication dynamics.
