Rumput laut atau seaweed termasuk tumbuhan berthallus yang banyak dijumpai hampir di seluruh pantai Indonesia, terutama wilayah pantai yang mempunyai rataan terumbu karang.  Perbedaan mendasar sistem hidupnya dengan tumbuhan darat adalah dalam pengambilan zat-zat makanan. Tumbuhan darat sangat bergantung pada akar sebagai alat pengambil/ penyerap zat hara dari substrat, sedangkan rumput laut menyerap zat hara yang dibutuhkan bagi pertumbuhannya dari medium air dengan cara difusi melalui permukaan substansi fisiknya.Penelitian ini bertujuan untuk mengetahui struktur komunitas rumput laut di perairan Pasir Panjang Pulau Limbah, Kecamatan Paguyaman Pantai, Kabupaten Boalemo, Provinsi Gorontalo. Metoda penelitian yang digunakan adalah bersifat diskriptif.Adapun pengumpulan data dilakukan dengan metode sample survey methods. Hasil penelitian menunjukan bahwa perairan Pulau Limbah di dominasi oleh Rumput Laut Coklat dengan kelimpahan tertinggi Padina australis. Nilai Indeks Keanekaragaman (H’) Rumput Laut tertinggi terdapat pada stasiun C dengan nilai rerata: 1,854 dan yang terendah pada Stasiun A dengan nilai rerata: 1,469. Nilai Indeks Keseragaman (E)  nilai tertinggi terdapat pada Stasiun C dengan nilai rerata: 0,679 dan terendah pada stasiun A dengan nilai rerata: 0,668. Nilai indeks Dominansi (C) tertinggi terdapat pada Stasiun A dengan nilai rerata : 0,251 dan nilai terendah stasiun B dengan nilai rerata: 0,187. Analisis Ragam (Anova) menunjukan bahwa stasiun penelitian memberikan perbedaan yang nyata (P≤0,05) terhadap nilai Indeks Keanekaragaman (H’), Indeks Keseragaman (E) serta Indeks Dominasi (C).  Seaweed including thallus plants that are found almost all over the coast of Indonesia, especially on beaches that have coral reefs. Seaweed is a photosynthetic organism as well as plants on land. The fundamental difference of his life system is in the taking of food substances. Ground plants realy heavily on roots as a nutrient removal device from the substrate, while seaweed absorbs the nutrients needed for its growth from the water medium by diffusion through the surface of its physical substance. This study aims to determine the structure of seaweed communities in Limbah Island Waters, District Paguyaman Beach. The results showed that the waters of Limbah Island is dominated by brown seaweed with the highest species abundance was Padina australis. The highest index value of Seaweed diversity (H’) was found at station C with average: 1,854 and the lowest at station A with a mean of: 1,469. For uniformity index value (E) the highest value is at station C with average: 0,679 and the lowest at station A with a mean of: 0,668. The highest index value of dominance (C) is at station A with a mean of: 0,251 and the lowest value at station B with a mean of: 0,187. The result of the analysis of variance (Anova) showed that the research station give a significant difference (P≤0,05) to the Diversity Index (H’), Uniformity Index (E) and Domination Index (C).

Penelitian ini bertujuan untuk mengetahui pelaksanaan mediasi sengketa ekonomi syariah dan hasil mediasi sengketa ekonomi syariah di Pengadilan Agama Makassar. Penelitian ini adalah penelitian hukum normatif dengan pendekatan Perundang-undangan, pendekatan kasus, dan pendekatan konseptual. Hasil penelitian menunjukkan bahwa pelaksanaan mediasi sengketa ekonomi syariah di Pengadilan Agama Makassar sudah sesuai dengan aturan dalam tahapan pramediasi dan tahapan proses mediasi, hanya saja belum optimal dikarenakan masih terdapat beberapa hal yang belum dimaksimalkan seperti pemilihan mediator yang selalu dikembalikan kepada ketua majelis hakim pemeriksa perkara untuk menunjuk mediator, dan belum digunakannya waktu yang maksimal dalam proses mediasi sengketa ekonomi syariah di Pengadilan Agama Makassar, sehingga hasil mediasi dalam perkara sengketa ekonomi syariah sejak tahun 2016-2019 di Pengadilan Agama Makassar belum ada satupun yang berhasil dimediasi.

Keanekaragaman jenis lamun dan struktur morfologi yang cukup besar pada Thalassia hemprchii dan Cymodocea rotundata memungkinkan ditumbuhi perifiton yang dapat meningkatkan produktivitas primer. Penelitian ini bertujuan untuk mengetahui kelimpahan perifiton pada T. hemprichii dan C. rotundata di Perairan Teluk Awur, Jepara. Penelitian dilaksanakan pada Bulan Juli 2020 menggunakan metode survei dan penentuan lokasi dipilih dengan menggunakan metode purposive random sampling, sedangkan metode pengambilan data lamun dengan metode line transect quadrant yang mengacu pada metode LIPI. Pengambilan daun lamun untuk pengamatan perifiton menggunakan metode sapuan daun yang selanjutnya diamati dengan menggunakan metode sensus yaitu pengamatan total dengan alat sedgwick rafter di bawah mikroskop. Nilai kelimpahan perifiton pada daun lamun T. hemprichii sebesar 27.635 ind/cm2. Sedangkan kelimpahan perifiton pada daun lamun C. rotundata sebesar 23.015 ind/cm2. Kelimpahan tertinggi perifiton terdapat pada jenis lamun Thalassia hemprichii, hal ini diduga karena Thalassia hemprichii mempunyai penampang daun yang lebih lebar. Perifiton yang mendominasi di Perairan Teluk Awur berasal dari Kelas Bacillariophyceae, diduga karena kelas ini memiliki kemampuan melekat pada substrat yang baik. Berdasarkan perhitungan Indeks Morisita maka diketahui bahwa sebaran perifiton di Perairan Teluk Awur didominasi pola sebaran mengelompok. Kelimpahan perifiton dengan kerapatan lamun di Perairan Teluk Awur memiliki hubungan cukup erat.The considerable diversity of seagrass species and morphological structures in Thalassia hemprchii and Cymodocea rotundata allows the growth of periphyton which can increase primary productivity. This study aims to determine the abundance of periphyton and its distribution patterns in the waters of Teluk Awur, Jepara. The study, which was conducted in July 2020, used a survey method and the location was selected using the purposive sampling method, while the seagrass data collection method used the line transect quadrant method which refers to the LIPI method. Seagrass leaves were collected for periphyton observations using the leaf sweep method, which was observed using the census method, namely total observation using the sedgwick rafter under a microscope. The abundance value of periphyton in Thalassia hemprichii seagrass leaves was 27,635 ind/cm2. While the abundance of periphyton in seagrass leaves of Cymodocea rotundata was 23,015 ind/cm2. The highest abundance of periphyton is found in the type of seagrass T. hemprichii, this is presumably because T. hemprichii has a wider leaf cross section. The dominant periphyton in Teluk Awur waters comes from the Bacillariophyceae class, presumably because this class has good adherence to the substrate. Based on the calculation of the Morisita Index, it is known that the distribution of periphyton in the waters of Teluk Awur, Jepara is dominated by a clustered distribution pattern. The abundance of periphyton and seagrass density on Parang Island is closely related.

The purpose of this study was to determine the effectiveness of the combination of tobacco leaf extract (Nicotiana tabacum) and green binahong leaf (Anredera cordifolia steenis) against myiasis. The study used the in vitro method for testing, while the leaf extract was obtained using the immersion method. This research was conducted using a completely randomized design (CRD) with a one-way pattern (One Way ANNOVA) with 6 treatments and 4 replications. The test uses fresh beef samples that have been rotten for 6 days at room temperature. The fresh weight of each meat sample was 100 grams. The treatments were P0 (control: only water), P1 (100% tobacco), P2 (100% green binahong), P3 (50% tobacco: 50% green binahong), P4 (70% tobacco: 30 green binahong) and P5 (30% tobacco: 70% green binahong). The results observed in the study included the time (seconds) required for larvae to come out of the meat after spraying on each treatment, the death of myiasis larvae at 5, 10, 15, and 25 minutes. The results showed that treatment P4 got the best results. compared with other treatments with a significant difference at the level of p <0.05.
