Abstract

The internet has become a fundamental necessity in various activities today. Stream Cyber Cafe, as an internet service provider, faces the challenge of maintaining network quality so that users can comfortably engage in activities such as gaming, streaming services, and social media. Load balancing, utilizing multiple internet sources from various ISPs, becomes a solution to enhance network efficiency and responsiveness. This research focuses on implementing the Dijkstra algorithm on MikroTik devices to determine the shortest path based on DNS server latency from various internet service providers (ISP). The main steps include configuring MikroTik devices, analyzing latency connections to DNS servers, and employing the Dijkstra algorithm. The Dijkstra algorithm, utilizing a Greedy approach, considers the minimum weight from the starting node to other nodes. Testing using the "PING" command provides information on the number of hops or steps required to reach each DNS server. Dijkstra adapts the shortest path based on latency, yielding optimal load balancing efficiency. Configuring MikroTik features, such as Firewall Mangle, Routing Table, and Routing Gateway, supports the functionality of the Dijkstra algorithm. Test results show that each ISP has a different shortest path to DNS servers, and the Dijkstra algorithm can determine the shortest path by considering time or latency factors. Although the author acknowledges some technical challenges during implementation, the proposed solution successfully overcomes these challenges. Thus, the use of the Dijkstra algorithm on MikroTik proves its effectiveness in enhancing the performance and reliability of the network in the Stream Cyber Cafe environment.

Abstract

The use of information technology in the agricultural sector is increasingly important to increase productivity and collaboration between farmers. This training explores the use of the E-Sawit Kita application as a learning medium and means of creating actual information for palm oil farmers. This training provides educational material related to best cultivation practices, land management and relevant market information. In addition, this research also involves intensive training for farmers in using the application, with the aim of increasing their understanding and skills in utilizing this technology. With interactive features, E-Sawit Kita allows farmers to share experiences, challenges and solutions, which in turn strengthens the collaborative network between them. The method used in this training is in the form of lectures, training material and questions and answers about using the E-Sawit Kita application. The research results show that E-Sawit Kita, through the training it provides, not only increases farmers' knowledge and skills, but also strengthens community solidarity through continuous exchange of information. These findings provide valuable insights for the development of similar applications to support sustainable agriculture in Indonesia.

Abstract

Coffee as one of Indonesia's plantation commodities that has very good development potential, considering that coffee consumption in Indonesia is still very high. Currently, the problem that occurs in Simalungun Regency is the conventional drying technology which is at risk of inconsistency in quality and taste so it needs to be fixed and given a solution. The partner team is the Mitra Sejati Jaya Cooperative, where community service activities are carried out in the Sait Buttu area, Pematang Sidamanik District, Simalungun Regency, North Sumatra which is one of the locations for planting Arabica coffee. The purpose of this activity is to create intelligent IT-based appropriate tools and technologies, namely the ARDUINO UNO Smart Sweetener as a solution to the problems of partners and coffee processing community groups, then improve coffee farmers in supporting improvements in the quality of Arabica coffee taste through efficient, portable, and environmentally friendly smart drying technology. The solution that can be provided is in the form of community service activities carried out by a team of lecturers and students from the Institut Teknologi Sawit Indonesia (ITSI) in the form of extension methods, socialization and education related to the technical innovation of the tool called the ARDUINO UNO Smart Sweetener. This community service activity was carried out for ±60 days consisting of the preparation stage consisting of a survey of completeness and preparation, assembly and finishing and pre-test, socialization and education and implementation of community service activities by ITSI lecturers and students. The activity was attended by people who are members of the Coffee Farmers, the Mitra Sejati Jaya cooperative partner team, local residents, lecturers from ITSI and supported by ITSI students. The results of this community service activity were able to educate the community in the Innovation of Mechanical Coffee Dryers.ABSTRAKKopi sebagai salah satu komoditas Perkebunan Indonesia yang memiliki potensi pengembangan masih sangat baik, mengingat konsumsi kopi di Indonesia masih sangat tinggi. Saat ini, permasalahan yang terjadi di Kabupaten Simalungun ialah teknologi pengeringan yang masih konvensional yang beresiko terhadap inkonsistensi mutu dan cita rasa sehingga perlu dibenahi dan diberi solusi. Tim mitra adalah Koperasi Mitra Sejati Jaya, dimana kegiatan pengabdian masyarakat dilaksanakan di daerah Sait Buttu, Kecamatan Pematang Sidamanik, Kabupaten Simalungun, Sumatera Utara yang merupakan salah satu lokasi penanaman kopi arabika. Tujuan dari kegiatan ini dapat menciptakan alat dan teknologi tepat guna yang cerdas berbasis IT yaitu Pemanis Pintar ARDUINO UNO sebagai solusi atas permasalahan mitra dan kelompok masyarakat pengolah kopi, kemudian meningkatkan petani kopi dalam mendukung perbaikan mutu cita rasa kopi arabika melalui teknologi pengeringan pintar yang efisien, portable, dan ramah lingkungan. Solusi yang dapat diberikan yaitu berupa kegiatan pengabdian masyarakat yang dilakukan oleh tim dosen dan mahasiswa Institut Teknologi Sawit Indonesia (ITSI) berupa metode penyuluhan, sosialisasi dan edukasi terkait teknis inovasi alat yang disebut Pemanis Pintar ARDUINO UNO. Kegiatan pengabdian masyarakat ini dilaksanakan selama ±60 hari yang terdiri dari tahap persiapan yang terdiri atas survei kelengkapan dan preparasi, perakitan dan finishing serta pra uji, sosialisasi dan edukasi serta pelaksanaan kegiatan pengabdian kepada masyarakat oleh dosen serta mahasiswa ITSI. Kegiatan dihadiri oleh orang yang tergabung dalam Petani Kopi, Tim mitra koperasi Mitra Sejati Jaya, warga setempat, dosen dari ITSI serta didukung oleh mahasiswa ITSI. Hasil dari kegiatan pengabdian masyarakat ini mampu mengedukasi masyarakat dalam Inovasi Alat Pengering Mekanis Kopi.

Abstract

Peningkatan emisi karbon dioksida (CO₂) ke atmosfer merupakan salah satu isu utama pemanasan global yang kerap dikaitkan dengan aktivitas perkebunan kelapa sawit. Namun, selain menghasilkan emisi, ekosistem kelapa sawit juga berperan sebagai penyerap karbon melalui tanaman utama maupun tanaman penutup tanah yang disebut beneficial plant. Penelitian ini bertujuan untuk menganalisis kadar karbon pada Mucuna bracteata sebagai tanaman penutup tanah leguminosa di lahan kelapa sawit. Pengukuran dilakukan dengan metode Organic Carbon Walkley-Black: Colorimetric Method menggunakan spektrofotometer UV-VIS. sedangkan pengukuran tidak langsung dilakukan melalui pemodelan Life Cycle Assessment (LCA) dengan bantuan perangkat lunak OpenLCA dan database Ecoinvent v.3. Hasil penelitian menunjukkan bahwa kadar karbon daun M. bracteata relatif stabil dengan koefisien variasi <0,2%, di mana nilai tertinggi tercatat pada sampel S2 sebesar 3,098 mg/mL per 0,1 g daun. Analisis LCA mendukung temuan tersebut dengan menunjukkan potensi kontribusi M. bracteata dalam menekan emisi bersih CO₂ pada subsistem perkebunan kelapa sawit. Konsistensi kadar karbon tersebut mengindikasikan kemampuan M. bracteata dalam menyerap karbon, sejalan dengan literatur yang menegaskan biomassa tinggi dan kontribusinya terhadap perbaikan sifat tanah, fiksasi nitrogen, dan pengendalian gulma. Dengan demikian, M. bracteata berpotensi menjadi agen penyimpanan karbon yang signifikan di ekosistem perkebunan kelapa sawit sekaligus mendukung penerapan perkebunan berkelanjutan dan baseline data untuk perdagangan karbon.
