Judul: Keterkaitan Sistem Sosial-Ekologi Sebagai Faktor Input Bagi Pengelolaan Perikanan Kembung (Rastrelliger spp.) di Pesisir Tanjung Satai, Kabupaten Kayong Utara, Kalimantan Barat
Abstrak: ABSTRACT Utilization of mackerel fishery resources is an effort to improve the fishermen's economy, in utilizing resources it is necessary to carry out management in favor of resource sustainability. The management of mackerel fishery resources in the TS coast within the framework of the socio-ecological system (SES) has not been well integrated. This study analyzes the components and connectivity of the socio-ecological system (SES) of the mackerel fish (Rastrelliger spp.) to formulate a management strategy in the TS Coastal waters. This research was conducted from June to July 2022 on the TS coast, Kayong Utara Regency, West Kalimantan. The social-ecological system (SES) approach was used in this study. Based on the results of the analysis, it shows that there is a strong relationship between the SES components. The resource user component (RA) has a strong relationship with mackerel fishery resources (RU), in the broader context of the resource system (RS), but tends to be weaker in the implementation of the resource management system (RG) in the TS coast. Management strategies can be carried out through good cooperation between (RA) and (RG) so as to create sustainable TS (RS) coastal waters and mackerel fishery resources (RU). Keywords: coast, mackerel fishery, resources, socio-ecological system, Tanjung Satai.

Judul: Utilization Analysis of The Mackerel (Rastrelliger spp) Resources in Tanah Laut District South Kalimantan Province
Abstrak: Tanah Laut is a district in South Kalimantan Province which has potential mackerel (Rastrelliger spp) resources. The objectives of the research were (I) to estimate level utilization of in the mackerels at Tanah Laut District, (2) to determine the appropriate fishing technology for catching mackerels around in Tanah Laut District, (3) to develop a strategy for mackerel fisheries in Tanah Laut District. Research activities which had been done included fishing gear analysis, stock analysis, financial analysis, scoring method and SWOT analysis. The utilization level of mackerel resources had achieved 77%. The purse seine fishery is more technologically appropriate and beneficial than the encircling gillnet fishery. The development strategies of the mackerel fisheries are (1) optimum utilization of the mackerel resouces, (2) development of mackerel fisheries to be more efficient and effective, (3) improvement of fisheries infrastructures and facilities, (4) improvement of government role and public participation in monitoring, controlling and surveilance of the mackerel resources.

Judul: Pembuatan Film Tipis Lithium Niobat (LiNbO3) Menggunakan Metode Chemical Solution Deposition (CSD) dengan Variasi Kecepatan Putar (Rpm).
Abstrak: Film tipis merupakan salah satu aspek yang mendapat perhatian sangat besar dalam bidang material, karena film tipis merupakan material menarik yang memiliki sifat optik yang sangat tergantung pada konstanta dielektrik, indeks bias, dan energi gap. Lithium Niobat (LiNbO3 ) dapat digunakan sebagai pelapis pada film tipis karena memiliki sifat piezoelektrik, electrooptical, pyroelectrical dan photorefractive yang sangat baik. Film tipis Lithium Niobat (LiNbO3 ) ditumbuhkan menggunakan metode Chemical Solution Deposition (CSD) dengan variasi kecepatan 3500 rpm, 5000 rpm, 6500 rpm, dan 8000 rpm. Metode ini memiliki keunggulan dapat mengontrol stokiometri film tipis dengan kualitas yang baik, prosedur yang mudah dan membutukan biaya yang relatif murah. Energi band gap yang dihasilkan dari film tipis Lithium Niobat (LiNbO3) berkisar antara rentang 2.1 eV – 2.8 eV dengan indeks bias berada pada rentang 2.18-3.2. Film tipis LiNbO3 memiliki parameter kisi a=b=5.54Ǻ dan c = 16.35 Ǻ. Struktur morfologi film tipis adalah permukaan yang homogen dan ukuran kristal berada pada rentang 0.417 μm – 0.680 μm.
