Abstract

Abstract This study aims to determine the influence of working capital, sales, and total asset turnover on net profit in plantation sub-sector companies listed on the Indonesia Stock Exchange during the 2021–2024 period. The research method used is quantitative with panel data regression analysis techniques using the Fixed Effect Model (FEM) approach. A total of 15 companies were selected as samples with a total of 60 observations. The findings indicate that working capital has no significant effect on net profit, which indicates that the effectiveness of the allocation of operational funds has not been optimized. In contrast, sales and total asset turnover show a significant negative effect on net profit. This suggests that increased sales activity and asset utilization may not necessarily result in higher profitability if not accompanied by cost efficiency. This aligns with the Resource Based View (RBV) theory, which posits that competitive advantage arises from the effective and strategic management of internal resources, especially in sectors facing dynamic conditions such as plantations. Abstrak Penelitian ini bertujuan untuk mengetahui pengaruh modal kerja, penjualan, dan perputaran total aktiva terhadap laba bersih pada perusahaan subsektor perkebunan. Metode penelitian yang digunakan bersifat kuantitatif dengan teknik analisis regresi data panel menggunakan pendekatan Fixed Effect Model (FEM). Sebanyak 15 perusahaan dipilih sebagai sampel dengan total observasi sebanyak 60 data. Hasil analisis menunjukkan bahwa modal kerja tidak berpengaruh secara signifikan terhadap laba bersih, yang mengindikasikan belum optimalnya efektivitas alokasi dana operasional. Sebaliknya, variabel penjualan dan perputaran total aktiva ditemukan berpengaruh negatif signifikan terhadap laba bersih. Hal ini menunjukkan bahwa peningkatan aktivitas penjualan dan penggunaan aset belum tentu menghasilkan profitabilitas yang lebih tinggi jika tidak dibarengi efisiensi biaya. Temuan ini menguatkan teori Resource Based View (RBV), yang menekankan bahwa keunggulan kompetitif diperoleh melalui pengelolaan sumber daya internal secara efektif dan strategis, khususnya dalam menghadapi dinamika sektor perkebunan

Abstract

Terdapat daya tarik wisata bahari yang berkembang di Desa Gebang Mekar ini yaitu Pantai Baro. Revitalisasi tempat wisata Gebang terpadu merupakan sebuah upaya penting untuk menghidupkan kembali keindahan alam yang terpendam dan menjadikannya destinasi yang tak terlupakan bagi para pengunjung. Meskipun keindahan alam Gebang Terpadu telah terlupakan akibat kesederhanaan dan kurangnya perhatian, namun harapan untuk menghidupkannya kembali tumbuh subur. Berbagai strategi telah dipertimbangkan untuk pengembangan tempat wisata Gebang Terpadu, yang meliputi membersihkan area wisata Pantai Baro dari sampah dan tanaman liar, pemeliharaan fasilitas umum seperti tempat parkir, dan  area istirahat, serta melibatkan partisipasi aktif masyarakat lokal dalam pengelolaan dan pengembangan tempat wisata. Selain itu, penanaman mangrove di sekitar Taman Baro, melibatkan komunitas lokal dalam upaya pelestarian lingkungan, dan melaksanakan program keberlanjutan lingkungan juga merupakan strategi penting.

Abstract

Salah satu persoalan kesehatan yang cukup besar di kota Semarang adalah penyakit DBD, berdasarkan data yang dirilis DINKES kota Semarang sampai bulan Juni 2024 yaitu sebesar 237 kasus. Melalui Kader FKK (Forum Kesehatan Keluarga) di Kelurahan, Pemerintah kota Semarang berupaya menekan kasus DBD dengan program Pembarantasan Jentik Nyamuk (PJN). Dalam pelaksanaannya, sering kali ditemukan kendala dalam pengumpulan dan analisis data lapangan yang dapat menghambat efektivitas program. Para Kader FKK juga belum memiliki kemampuan yang cukup untuk memanfaatkan teknologi. Salah satu solusi untuk meningkatkan pemantauan adalah dengan memanfaatkan teknologi informasi. Metode yang digunakan dalam kegiatan ini dalam bentuk ceramah dan praktek mengenai penggunaan Google Forms melalui ponsel pintar. Evaluasi kegiatan juga dilakukan berupa kuisioner yang diisi peserta terkait dengan kegiatan yang telah diikuti. Hasil yang dicapai dari kegiatan ini adalah peningkatan kemampuan mitra dalam membuat aplikasi pemantauan PJN menggunakan Google Forms. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk memberikan solusi teknologi sederhana namun efektif dalam mendukung program kesehatan lingkungan.

Abstract

This study aims to analyze the effect of Brand Image, electronic word of mouth (E-WOM), and service quality on consumer stay decisions at Hotel 88 Mangga Besar 120. A quantitative method with accidental sampling was applied to 150 respondents, and the data were analyzed using multiple linear regression. The results show that all three variables have a positive and significant influence on stay decisions, both partially and simultaneously, with Brand Image emerging as the most dominant factor. The model explains 48.3% of the variation in consumer decisions. These findings suggest that hotel managers should strengthen brand communication, manage online reviews effectively, and maintain service quality consistently to enhance consumer decision-making and increase occupancy rates.

Abstract

The Dieng region in Central Java, Indonesia, is a major horticulture commodities center, covering approximately 3,000 hectares of Andisols. Since the 1980s, long-term use of organic and inorganic fertilizers as well as pesticides has led to the accumulation of heavy metals, such as lead (Pb) and cadmium (Cd). Pb contents in Andisols generally remain below the Environmental Protection Agency (EPA) standard, except in Sikunang, and Cd exceeds the standard in both Sembungan and Jojogan Wonosobo. In potato tubers, Pb content exceeds the SNI 7378-2009 threshold in Wonosobo and Pekasiran Banjarnegara, while tubers from other areas are below standard. The Cd content in tubers from Jojodan and Kalilembu Wonosobo, as well as Pekasiran and Kepakisan Banjarnegara, also surpasses the standard, but in other areas, it is below standard. The use of remediators composed of chicken manure enriched with Pseudomonas sp, Dark Septate Endophytes (DSE), and Citronella (Cymbopogon nardus) as phytoremediators reduced Pb and Cd levels in both soil and potato tubers. Therefore, the best remediation strategy for mitigating heavy metal contamination included the combination of Pseudomonas sp., DSE, and citronella. These treatments did not significantly affect potato yield. The correlation among variables shows that Pb and Cd levels in potato tubers were influenced by the respective soil concentrations. However, no correlation was observed between soil heavy metal content and tuber yield.

Abstract

The internet itself is a public network that can connect anyone into a very large network, and of course there are threats of data theft in it, VPN is a communication technology that allows an employee in the office to connect to a public network and use it to join the local network. . The advantage of a VPN is that the data sent via a VPN is encrypted so it is quite safe and the secret is maintained even though it is through the internet network, a comparison analysis of VPN performance between the SSTP (Secure Socket Tunneling Protocol) protocol and the Open VPN protocol will be carried out to determine the Quality Of Service (Qos) performance of both For this protocol, a study is needed to determine the use of the method so as to produce an optimal QOS (Quality of Service)

Abstract

The Border Gateway Protocol (BGP), as the core internet routing protocol, lacks built-in security mechanisms, making it vulnerable to Man-in-the-Middle (MITM) attacks and sniffing. This research aims to test the effectiveness of an OpenVPN-based secure tunnel in enhancing the security of BGP peering sessions while analyzing its impact on network performance. The method used is an experiment with a pre-test and post-test design, comparing conditions before and after OpenVPN implementation between two routers on different platforms (Linux/FRRouting and MikroTik RouterOS). Test results show that OpenVPN successfully secures BGP communication by encrypting all traffic, thereby eliminating the risk of plaintext reading and passive MITM attacks. However, this implementation introduces a performance trade-off: latency increases by 2.6 ms (50%), throughput decreases by 289 Mbps (30.6%), and CPU utilization surges up to 60% due to encryption overhead. Nonetheless, BGP session stability is maintained with 99.95% uptime. The research concludes that OpenVPN is an effective solution for securing BGP in high-risk environments, with the caveat that hardware capacity and bandwidth requirements must be evaluated to minimize performance overhead impact.
