Judul: Eksplorasi Dinamika Keterkaitan Social-Ecological System Perikanan Lobster di Pesisir Kabupaten Garut, Provinsi Jawa Barat
Abstrak: Lobster (Panulirus spp.) adalah salah satu komoditas yang memiliki nilai jual yang tinggi. Indonsesia merupakan salah satu negara di dunia yang melakukan ekpor lobster dengan posisi ke-17 di dunia. Sedangkan di tingkat ASEAN, Indonesia merupakan eksportir utama lobster dunia. Tujuan penelitian ini adalah memetakan sub sistem dan dinamika keterkaitan antar sub-sistem social-ecological system (SES) perikanan lobster yang terdiri dari resources system (RS) ekosistem perairan Kabupaten Garut, resources unit (RU) perikanan lobster, resources actors (RA) dan resources governance (RG) di perairan Kabupaten Garut. Penelitian ini dilaksanakan mulai bulan Mei hingga Juni 2023. Komponen SES yang memiliki hubungan sangat kuat adalah RU dengan RA. Hubungan antara RA yang memanfaatkan sistem RS dan RU diatur dengan sistem tata kelola di pesisir Kabupaten Garut (RG)., Lobster (Panulirus spp.) is one commodity with high selling value. Indonesia is one of the countries in the world that exports lobster with the 17th position in the world. While at the ASEAN level, Indonesia is the world's main lobster exporter. The purpose of this study is to map the sub-systems and the dynamics of interrelationships between sub-systems of the social-ecological system of lobster fisheries consisting of the resource system (RS) of the Garut Regency water ecosystem, resource units (RU) of lobster fisheries, resource actors (RA) and resource governance (RG) in Garut Regency waters. This research was conducted from May to June 2023. SES components that have a very strong relationship between RU and RA. Relationship between RA using RS and RU regulated with the coastal governance system in Garut district (RG).

Judul: Eksplorasi Dinamika Keterkaitan Social-Ecological System Perikanan Lobster di Pesisir Kabupaten Pangandaran, Provinsi Jawa Barat
Abstrak: Lobster merupakan komoditas ekonomis penting yang potensial di pesisir Pangandaran. Pengelolaan sumberdaya lobster dalam kerangka Social-Ecological System (SES) di pesisir Pangandaran belum teridentifikasi dengan baik. Penelitian ini bertujuan untuk memetakan dan menganalisis dinamika keterkaitan Social-Ecological System (SES) perikanan lobster (Panulirus spp.) dengan komponen-komponen berupa resources systems (RS), resources units (RU), resources actors (RA), dan resources governance (RG) sebagai input untuk merumuskan strategi pengelolaan perikanan lobster yang berkelanjutan di pesisir Pangandaran. Pengambilan data dilakukan pada bulan Mei hingga Juni 2023 di Kecamatan Cimerak, Kabupaten Pangandaran. Interaksi keterkaitan yang kuat terjadi pada hubungan antar komponen RA dan RS dimana perubahan interaksi dari keduanya dapat mengakibatkan adanya perubahan pada komponen lainnya., Lobster is a potentially important economic fisheries commodity on the coast of Pangandaran. Lobster fisheries management using the Social-Ecological System (SES) framework on the Pangandaran coast has not been well identified. This research aims to map and analyze the dynamics irrelationship between the Social-Ecological System (SES) of lobster (Panulirus spp.) fisheries with the components of resource systems (RS), resource units (RU), resource actors (RA), and resource governance ( RG) as input for developing a sustainable lobster fisheries management strategy on the Pangandaran coast. Data was collected from May to June 2023 in Cimerak District, Pangandaran Regency. Strong interrelated interactions occur in the relationship between RA and RS components where changes in the interaction of the two can result in changes in the other components.

Judul: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
