Abstract-Urban traffic control is the main factor that contributes to traffic jam. Approach in distributed Urban traffic control has been developed in several research, but the coordinating controller factor is basically a quite complicated task to tackle, because between intersection have dependency, so required a method of distributed control system capable for synchronizing between intersections. In this paper we present architecture of decentralized self-organizing traffic control with swarm-self organizing map in real situation even on non-structure intersections like in Jakarta (Indonesia). Based on the proposed architecture we have been implemented Traffic Signal Control System for controlling traffic lights in which the coordination between the intersections is implemented using distributed swarm self-organizing map. Traffic Signal Control System were tested in a simulated real-road scenario of Jakarta. By means of the computer simulation, the application of distributed swarm signal self-organizing control is proved effective in urban traffic.

Enrofloxacin (EXF) in fish comes from feed, water, and the environment. Through these three sources enrofloxacin will accumulate in the body of the fish. Enrofloxacin enters the metabolic process and enters the tissue so that fish meat containing enrofloxacin will be produced, and can threaten human health such as the occurrence of carcinogenic potential. Tests have been carried out to test the time of decay of enrofloxacin in catfish after various doses, namely group A (control), B (25 ppb) and C (50 ppb). The fish samples analyzed were catfish which were tested by Enrofloxacin using the ELISA (Linked Immunosorbent Assay) method. The results showed that the last residual content of enrofloxacin was added to feed every day during the treatment of concentration for group B (17.89 ppb) and group C (17.47 ppb). However, the time for all enrofloxacin residues in catfish to be the same as the control or normal conditions turned out to take 80 days with enrofloxacin residual concentrations for group B (2.12 ppb) and group C (5.13 ppb)

Subak, an inherited communal water management in the agricultural system for centuries in Bali Island – Indonesia, has been widely known as a UNESCO World Heritage Culture since 2012. Subak’s philosophy “Tri Hita Karana” (three causes of prosperity) has become the foundation for Subak members to practice sustainable agriculture. Its institutional and operational practices were found to be a good example of ecosystem services management in a cultural way. In an attempt to assess Subak’s eligibility as a Nature-based Solutions (NbS) activities in ensuring the ecosystem services delivered to its people, we conducted a self-assessment using 8 criteria and 21 indicators based on NbS guidelines. The result shows that Subak addressed three out of seven societal challenges as a core of NbS: environmental degradation and biodiversity loss, food security, and water security. We also identified some problems and challenges faced by Balinese and Subak in terms of the system’s sustainability. We concluded that Subak could be categorized as an NbS, specifically NbS Type 2 for sustainability and multifunctionality of managed ecosystems. Supports from the central government both in terms of regulatory and policies are needed, as well as promoting Subak to other related sectors such ecotourism.

Kinetic Monte Carlo (KMC) is a non-deterministic computational technique for simulating atomistic motion. These simulations can be used to predict the formation of substances at the atomic level. This work describes a graphical user interface for a variant of the KMC simulation technique called Self-Learning Kinetic Monte Carlo (SLKMC) which is currently under development. We look at the SLKMC algorithm as well as the steps users take to extract useful information from the simulation data. Then we look at potential ways to enhance accuracy and productivity during the model description and analysis phases of simulations. The user interface described in this work includes support for the creation of initial condition data via mesh generation and global constant editing. It also provides improved support for simulation results analysis. Analysis features include animated 3D model visualization and statistical data representation. The architecture and implementation of software designed to carry out these enhancements is also discussed. We assess the usefulness of the implementation of the software using reviews conducted by developers and users of the SLKMC simulator. These reviews verify that the unified interface contributes to both the usefulness of the underlying simulation code and user productivity.

Kondisi keanekaragaman hayati Indonesia cukup mengkhawatirkan yang diakibatkan oleh kerusakan dan pemanfaatan yang berlebihan. Salah satu upaya menanggulangi masalah tersebut adalah pembangunan dan pengembangan taman keanekaragaman hayati (kehati). PT. Tirta Investama Pabrik Solok telah membangun taman kehati sejak tahun 2014, dimana sampai saat ini belum terdata dampak positif dari keberadaan taman kehati tersebut. Penelitian ini dilaksanakan untuk mendapatkan data keanekaragaman jenis tumbuhan dan jenis burung serta cadangan karbon di areal taman kehati Solok. Menggunakan metode sensus dengan mendata dan mengidentifikasi serta mengukur dbh seluruh tumbuhan yang ada. Pengamatan jenis burung menggunakan metoda simple list method dengan mengunakan buku panduan identifikasi burung. Hasil identifikasi mendapatkan sebanyak 74 jenis tumbuhan yang tergabung dalam 34 famili dengan jumlah individu 250 batang. Jenis burung yang teridentifikasi sebanyak 14 jenis. Total cadangan karbon tersimpan dalam areal taman kehati seluas 2,5 ha adalah 28,07 ton dengan vegetasi tingkat pohon sebagai penyumbang cadangan karbon terbanyak yaitu 24,48 ton atau 87 %. Kata Kunci: Taman Kehati, keanekaragaman, stok karbon
