Abstract

Cork Fish (Channa striata) and Baung Fish (Mystus)is a fish that has a high nutritional value and many produced from the Musi City Palembang River. Activities in the region can produce waste that can harm water environment such as industrial waste and domestic household waste. This research aims to determine the level of heavy metals lead (Pb) in Cork fish (Channa striata) and Baung Fish (Mystus) originating from the Musi city of the river Palembang. Random sampling method on fish suppliers in the traditional market of Palembang by using the method of atomic absorption spetrophotometry. Based on the results of measurements made, heavy metal content of Pb Cork fish meat average of 0.1036 mg/kg and on average Baung fish meat 0.1425.As for the gills of the cork, the rate of Thymbalnya ranges between 0,0911-0,0953 mg/kg and in the gills of the fish range between 0,1117-0,1843 mg/kg. There are heavy metal contaminants in the meat as well as the fish Cork (Channa striata) and Ikan Baung (Mystus) derived from the waters of the Musi River that is the city of Palembang where the heavy metal levels lead to the fish is higher compared with fish meat.

Abstract

Komering River is a river that flows in Serdang Menang Village, Sirah Pulau Padang sub district, Ogan Komering Ilir Regency. Most of the community activities around the Komering River are utilizing river water for household activities, agriculture, sand mining and fish farming. With the increasing variety of activities contained in the Komering River, it can have an effect on the quality of the waters. Changes in water quality can be knoen from physical, chemical and biological indicators. For biological indicators, monitoring can be done through the presence of aquatic biota. One of the aquatic biota that is very susceptible to changes in the aquatic environment is plankton. The purpose of this study was to determine the abundance of plankton as a bioindicator of the tropic status of waters in the Komering River.  The study was conducted from March to April 2018 at the Komering River in Serdang Menang Village, Sirah Pulau Padang Sub District, Ogan Komering Ilir Regency. The method used is a field survey by determining the sampling station based on purposive random sampling. Sampling was carried out at 3 stations, namely the sand mining area (station 1), the KJA system fis cultivation area (station 2) and the densely populated residential area (station 3). Based on the result of study, the composition of plankton found in the Komering River consisted of phytoplankton (Bacillariophyceae, Chlorophyceae, Cyanophyceae) and zooplankton (Mastigophora, Monogononta, Crustaceans). The highest abundance index of phytoplankton and zooplankton is found in station 2 (dense area of floating net cages) which iis 3.140 individuals/liter and 100 individuals/liter.  Trophic status of Komering River waters in Serdang Menang Village based on phytoplankton abudance including oligotrophic waters, while based on zooplankton abudance including mesotrophic waters.

Abstract

Pengangguran terbuka (Open Unemployment) adalah penduduk usia kerja yang tidak mempunyai pekerjaan apapun, yang secara aktif mencari pekerjaan. Backpropagation adalah salah satu algoritma pada jaringan syaraf tiruan (JST) yang digunakan untuk meramalkan atau prediksi data. Dalam penelitian ini akan diramalkan Tingkat Pengangguran Terbuka (TPT) di Provinsi Maluku. Berdasarkan hasil analisis pelatihan  diperoleh rata-rata keberhasilan permalan  sebesar 92.59%  dengan error terkecil yaitu MAPE = 0.0741%. Hasil peramalan 5 tahun ke depan menunjukan data fluktuatif dari tahun 2019 (9.5134) sampai tahun 2023 (9.7924).

Abstract

Hutan mangrove memiliki peran dalam mempertahankan fungsi ekologis dan penyangga kestabilan ekosistem daerah pesisir. Aktivitas kegiatan masyarakat dipesisir perairan seperti pelabuhan, jalur transportasi, pemukiman dan pariwisata memberikan dampak terhadap sumbangan jenis-jenis polutan yang masuk kedalam perairan. Jenis tumbuhan mangrove secara alami berpotensi dapat meminimalisir adanya serapan logam berat seperti jenis Buguiera gymnorriza dan Rhizophora apiculata. Penelitian ini dilakukan bulan Mei sampai dengan Juni 2018. Lokasi penelitian di pesisir hutan mangrove Kuala Langsa, Aceh. Metode penelitian ini deskriptif eksploratif dengan mendeskripsikan satuan serapan logam berat Pb, Cu dan Zn pada jenis tumbuhan mangrove dan Fitoremidiasi jenis tumbuhan mangrove. Analisis data dengan Atomic Absorption Spectrophotometer (ASS) dan Fitoremidiasi (FTD), berdasarkan sampel bagian akar, daun  dan sedimen. Hasil penelitian serapan logam pada jenis Buguiera gymnorriza pada akar, daun dan sedimen secara berurutan pada Zn (seng) 5,833 ppm; 0,598 ppm; 6,775 ppm. Cu (tembaga) 0,0008 ppm.

Abstract

Kebutuhan jagung nasional terus meningkat seiring jumlah penduduk dan peternak dalam memanfaatkan jagung sebagai bahan pangan, pakan dan bahan baku industri. Produksi jagung nasional belum mampu memenuhi permintaan pengguna, sehingga diperlukan upaya peningkatan produksi melalui pengaturan jarak tanam dan penggunaan varietas hibrida yang sesuai dengan tingkat populasi dan berproduksi maksimal. Tujuan penelitian untuk mengetahui pengaruh tingkat populasi terhadap pertumbuhan dan produksi jagung hibrida. Penelitian dilaksanakan bulan November 2018 – Februari 2019 di Kebun Percobaan Bajeng, Gowa Balai Penelitian Tanaman Serealia. Penelitian menggunakan rancangan acak  kelompok (RAK) 2 faktor dengan 3 ulangan. Faktor pertama varietas : 1. Nasa 29, dan 2. Bima 2. Faktor kedua populasi tanaman, yaitu 1. jarak tanam (140 - 40) x 12.5 cm  (88.888 tan/ha), 2. (160 - 40) 20 cm (2 biji/lubang) (100.000 tan/ha), 3. (160 - 30) x 15 cm (70.125 tan/ha), 4. (160 - 40) x 12.5 cm. (80.000 tan/ha), 5. 70 x 20 cm (71.428 tan/ha). Peubah yang diamati : komponen agronomis (tinggi tanaman (cm) 35 hst dan 110 hst, tinggi letak tongkol (cm) 110 hst, panjang daun (cm)), komponen hasil : panjang tongkol (cm), jumlah baris, biji dalam baris, dan  bobot 100 biji), dan produksi biji (t/ha). Hasil dari penelitian menunjukkan varietas berpengaruh sangat nyata terhadap jumlah biji dalam baris, tinggi tanaman dan letak tongkol (110 hst) dan berpengaruh nyata pada panjang tongkol, namun tidak berpengaruh nyata terhadap produksi, bobot 100 biji, jumlah baris, tinggi tanaman (35 hs) dan jumlah daun (35 hst), sedang populasi/jarak tanam tidak berpengaruh nyata dan tidak terjadi interaksi nyata varietas dan tingkat populasi/jarak tanam terhadap seluruh parameter. Produksi tertinggi varietas Nasa 29 yaitu  8,86 t/ha (populasi 88.888 tan./ha) dan Bima 2 yaitu 8,12 t/ha (populasi 71.248 tan./ha).

Abstract

Synthesis and characterization of the chitosan/PEO solid polymer membranes were carried out to determine the morphological structure, crystal structure and functional groups. Synthesis of the chitosan/PEO solid polymer membrane was carried out by solution casting method. Characterization was performed using the FTIR (Fourier Transform Infra Red), XRD (X-ray Diffraction), SEM (Scanning Electron Microscopy) and EIS (Electrochemical Impedance Spectroscopy). The FTIR results showed that the chitosan/PEO solid polymer membrane interacted with the –OH and C-H functional groups at wave numbers 1500 - 945 cm-1 and formed a bending bond between functional groups  of the C-C and –NH3. The SEM results showed that the homogeneous agglomeration was formed on the membrane surface due to the addition of PEO powder. This causes the formation of bonds between atoms to unstable. The XRD results obtained that the chitosan/PEO solid polymer membrane pattern tended to have a semicrystalline structure. The graph of the EIS results shows the electric permittivity does not form a semicircular arc. There was no grain response on the chitosan / PEO solid polymer membrane. The results of SEM, XRD, FTIR and EIS characterization show that chitosan /PEO solid polymer membranes can be used as an alternative to solid polymer electrolytes.

Abstract

The purpose of this study was to determine the level of noise caused by vehicles on campus A at PGRI Palembang University. Noise measurements were carried out in 3 different places that were passed by the vehicles of employees and students, namely the parking lot of Building A, Building B and Building C. The study was conducted in October 2020 for 5 working days of data collection. The measurement result data is analyzed by calculating the respective Leq as a measured noise level, then the Leq is compared with the quality standards recommended by the government for noise in educational institutions. The results showed that the noise in the campus A environment of PGRI Palembang University was in the range of Leq 57.3012 - 73.9548 dBA and did not meet the noise level quality standard for educational institutions, namely 55 dBA. This is because the location of the measurement is close to the traffic of vehicles.
