A Mobile Ad Hoc Network (MANET) protocol requires proper settings to perform data transmission optimally. To overcome this problem, it is necessary to select the correct routing protocol and use the routing protocol’s default parameter values. This study examined the effect of route request parameters, such as RREQ_RETRIES and MAX_RREQ_TIMOUT, on the Ad Hoc On-demand Distance Vector (AODV) protocol, which was then compared with the default AODV performance Optimized Link State Routing (OLSR) protocols. The performance metrics used for measuring performance were Packet Delivery Ratio (PDR), throughput, delay, packet loss, energy consumption, and routing overhead. The results show that the OLSR protocol has a smaller delay than the AODV protocol, while in other measurements, the AODV protocol is better than OLSR. By reducing the combination value of RREQ_RETRIES, MAX_RREQ_TIMEOUT in AODV routing to (2, 10 s) and (3, 5 s), the protocol’s performance can be improved. The two combinations result in an average increase in throughput performance of 3.09%, a decrease in delay of 17.7%, a decrease in packet loss of 27.15%, and an increase in PDR of 4.8%. For variations in the speed of movement of nodes, 20 m/s has the best performance, while 5 m/s has the worst performance.

This research proposed a method for scriptio continua management on the learning application-based transliteration to the Balinese Script. It has not been conducted yet and is important since the proposed method eases the learning of the Balinese Script as the transliteration output. This research is a technological preservation effort to the endangered Balinese local language knowledge in Indonesia through the multi-discipline collaboration between Engineering (especially on applied Computer Science) and Language discipline. The proposed method took care of two related aspects, i.e.: (1) The Balinese Script uses scriptio continua as a style of writing without spaces, so do its transliteration result to the Balinese Script; and (2) A switching management between scriptio continua and non-scriptio continua style is needed by the learning application for the ease of learning through the visual analysis of the transliteration output which is the Balinese Script. This study was conducted on the pioneering web-based transliteration learning application, BaliScript, with the Latin text as the input and the Balinese Script as the output. Through the experiment, the proposed method gave the expected transliteration result on scriptio continua management, which can switch between three styles of writing, i.e.: (1) scriptio continua; (2) unconditional non-scriptio continua; and (3) conditional non-scriptio continua.

Isu kepedulian lingkungan hidup dewasa ini menjadi topik utama yang sangat penting untuk disikapi. Pemerintah mendorong upaya-upaya untuk melestarikan fungsi lingkungan hidup dan mencegah terjadinya pencemaran atau kerusakan lingkungan hidup yang diakibatkan oleh beberapa faktor, salah satunya adalah sampah. Bank sampah merupakan salah satu solusi kepedulian lingkungan dengan konsep pengumpulan sampah kering seperti kertas, karton, kaleng, majalah, dan sampah plastik lainnya, yang berasal dari rumah untuk memaksimalkan partisipasi warga untuk lebih peduli terhadap lingkungan sekitar, dan menambah nilai ekonomi dari sampah. Mitra dalam pengabdian ini adalah Kelompok Bank Sampah “Gilimanuk” dan Kelompok Bank Sampah “Gili Karya Dewata” yang keduanya berada di desa Gilimanuk, kecamatan Melaya, kabupaten Jembrana, Bali. Tim mencoba membantu kedua mitra ini karena memiliki permasalahan antara lain: 1) bahan baku terbatas dari desa Gilimanuk; 2) penjualan terbatas di kabupaten Jembrana dan masih tradisional belum berbasis internet; 3) model produk yang masih sedikit; 4) pembukuan yang kurang terstruktur; dan 5) pelabelan pada produk yang belum ada. Kegiatan pengabdian ini diharapkan dapat meningkatkan penjualan kelompok mitra, menyejahterakan masyarakat sekitarnya, dan berperan penting dalam program kepedulian lingkungan.

We are in a time when a large number of electronic devices influence human interaction with the environment. The physical place where these various devices interact with each other to provide useful services for end-users gives birth to the concept of a Smart Environment. The interaction of the multiple devices that make up a smart environment produces a large amount of information or Big Data problems, so the insertion of the Internet of Things (IoT) technology in the environment is essential. IoT integration and cloud computing technology are needed as the impact of evolution on the next generation of smart environments. Trends in research related to IoT and Smart Environments are increasing rapidly beyond the trend of Smart City that first emerged. This paper reviewed current trends about smart environments, architectural concepts, frameworks, and applications of IoT-based Smart Environments.

The decreasing use of Balinese Script, including its Latin-to-Balinese Script transliteration knowledge, has caused concern over the threat of extinction of this part of Balinese culture. This research is aimed to preserve that knowledge through the technological approach by collaboration between Engineering and Language disciplines. It provided lessons learned from the analysis of the computer-based implementation of Latin to Balinese Script transliteration on a relatively large document. This study has never been conducted yet and added certain perspectives also strengthened computer-based transliteration knowledge, as part of Balinese Language ubiquitous learning. The analysis was conducted on pioneering Aksara Bali Simbar Dwijendra (SD) web application that basically receives Latin text input and outputs Balinese Script based on Bali SD font. Through the experiment, ten categorized lessons were exposed and learned. Future work to enrich this transliteration knowledge is by conducting more exploration on computer-based implementation using dedicated Balinese-Unicode fonts.

Microelectronic technology that supports the establishment of wireless sensor networks (WSN) has brought hope to the ease of Internet of Things (IoT) technology that can generate smart environments. A WSN consists of a collection of sensor nodes that are small, intelligent, and inadequate in storage, energy, and processing power. One of the well-known routing techniques in WSN is LEACH. There have been many LEACH studies and their development with random node distribution. Here we designed several scenarios in WSN routing with the position of the sensor nodes specified in the mapping area. MATLAB simulation results show network lifetime can be extended by reducing data packet size. In five experiments, the number of 40 nodes was the optimal number to extend network lifetime. Each scenario has advantages and disadvantages that can be referenced in developing the LEACH protocol.

Tujuan yang ingin dicapai dalam penelitian ini adalah 1) menghasilkan rancangan prototipe robot alat monitor dan observasi bawah air (AMOBA) berbasis ROV (remotely operated vehicle) yang mampu bergerak di dalam air; 2) melakukan uji coba prototipe robot AMOBA di bawah air dan mengkaji hasilnya; 3) memperoleh kinerja prototipe robot AMOBA sebagai alat yang memiliki kemampuan survey (monitoring and observation) bawah air. ROV merupakan robot bawah air yang dikendalikan oleh operator dalam pengoperasiannya, dan didukung oleh perangkat kendali dalam pengoperasiannya. Pada penelitian ini dikembangkan prototipe ROV yang mampu bernavigasi di bawah air dengan kendali berbasis mikrokontroller dari permukaan air menggunakan kabel 15m dan beberapa aktuator dengan propellernya dari pompa air. Pompa air yang digunakan sebanyak 8 buah (2 buah pompa untuk belok kiri, 2 buah pompa untuk belok kanan, 2 buah pompa untuk maju ke depan, dan 2 buah pompa untuk naik ke atas). Robot AMOBA yang dikembangkan dilengkapi dengan IPCamera yang dapat dikendalikan untuk menampilkan visual bawah air dan dapat diputar sepanjang 1200 (kiri, kanan, atas, dan bawah). Metode yang akan digunakan untuk mencapai tujuan diatas adalah metode penelitian dan pengembangan (research and development) atau R&D menurut Borg dan Gall. Analisis dalam penelitian ini menggunakan konsep SMART (specific, measurable, achievable, realistic, time-based). Hasil penelitian menunjukkan rata-rata kecepatan robot 21,5 cm/detik dengan bobot 23kg. Kecepatan robot tergolong lambat dan saat pergerakan di awal pelan kemudian perlahan-lahan cepat akibat perlunya daya yang kuat untuk mendorong robot di awal. Semakin dalam robot di air maka tekanan air semakin besar dan berakibat terhentinya pompa air bekerja. Pompa air yang digunakan hanya dapat bekerja maksimal hingga kedalaman 3 m. Sehingga diperlukan aktuator dengan propeller yang lebih kuat apabila ingin dikembangkan untuk menjangkau kedalaman air lebih dari 3 m.
