PELATIHAN PENGOLAHAN IKAN MALALUGIS (Decapterus macarellus) KEPADA IBU-IBU PKK DESA TIHU KECAMATAN BONEPANTAI KABUPATEN BONE BOLANGO

Tihu Village is one of the coastal villages around Tomini Bay. This village has the potential of malalugis fish (Decapterus macarellus), which is often abundant but has not been optimally exploited. The problem in Tihu Village is that the catch of malalugis fish is usually plentiful in certain seasons, and people often throw it away. So far, there has been no community effort in processing these fish resources. Through community service programs, community empowerment, especially the Family Welfare Empowerment Organization (PKK), is utilized to exploit the potential of malalugis fish to be processed products that can support the community’s welfare. This activity aims to provide training to the Family Welfare Empowerment Organization (PKK) in utilizing the resources of malalugis fish to be processed products of fishery products. The method applied in the implementation of community service activities in Tihu Village is through training methods with participatory learning techniques and direct practice of processing malalugis fish. This activity’s output is the creation of processed malalugis fish products in the form of croquettes and nuggets. The long-term target is processed malalugis fish products can be an alternative source of livelihood that can improve the community’s economy. --- Desa Tihu merupakan salah satu desa pesisir Teluk Tomini. Desa ini memiliki potensi ikan malalugis (Decapterus macarellus) yang sering melimpah, namun belum dimanfaatkan secara optimal. Permasalahan yang ada di Desa Tihu adalah hasil tangkapan ikan malalugis sering melimpah pada musim-musim tertentu dan seringkali masyarakat hanya membuangnya begitu saja. Selama ini belum ada upaya masyarakat dalam melakukan pengolahan sumberdaya ikan ini. Melalui program pengabdian pada masyarakat ini dilakukan  pemberdayaan masyarakat khususnya ibu-ibu PKK untuk pemanfaatan potensi ikan malalugis ini menjadi produk olahan yang dapat menunjang kesejahteraan masyarakat. Tujuan kegiatan ini adalah untuk memberikan pelatihan kepada Ibu-ibu PKK dalam memanfaatkan sumberdaya ikan malalugis menjadi produk olahan hasil perikanan. Metode yang diterapkan dalam pelaksanaan kegiatan pengabdian di Desa Tihu ini ialah melalui metode pelatihan dengan teknik pembelajaran partisipatif dan praktek langsung pengolahan ikan malalugis. Luaran dari kegiatan ini adalah terciptanya produk olahan ikan malalugis berupa kroket dan nuget. Target jangka panjang adalah produk olahan ikan malalugis dapat menjadi alternatif sumber pencaharian yang dapat meningkatkan ekonomi masyarakat

Position Sensor-less and Adaptive Speed Design for Controlling Brush-less DC Motor Drives

This paper proposes a method for direct torque control of Brushless DC (BLDC) motors. Evaluating the trapezium of back-EMF is needed, and is done via a sliding mode observer employing just one measurement of stator current. The effect of the proposed estimation algorithm is reducing the impact of switching noise and consequently eliminating the required filter. Furthermore, to overcome the uncertainties related to BLDC motors, Recursive Least Square (RLS) is regarded as a real-time estimator of inertia and viscous damping coefficients of the BLDC motor. By substituting the estimated load torque in mechanical dynamic equations, the rotor speed can be calculated. Also, to increase the robustness and decrease the rise time of the system, Modified Model Reference Adaptive System (MMRAS) is applied in order to design a new speed controller. Simulation results confirm the validity of this recommended method

Spatial and temporal distribution of phytoplankton with emphasis on the harmful and toxic algae in the Limboto Lake

This study aims to describe Limboto Lake's condition based on the spatial-temporal abundance of phytoplankton and the presence of harmful algae species. Sampling was conducted in February, March, and April 2018 at six stations. The phytoplankton found in Limboto Lake consisted of 7 divisions from 80 species, namely Chlorophyta (35 species), Euglenophyta (17 species), Bacillarophyta (13 species), Cyanophyta (7 species), Cryptophyta (4 species), Dinophyta (3 species) and Chyrosphyta (1 species). The results of the phytoplankton distribution analysis in Limboto Lake varied on average among stations as well as observation times. The results show that the average of phytoplankton abundance at stations 1, stations 2, stations 3, and stations 4 categorized as medium polluted waters with 4,903 ind/L, 5,000 ind/ L, 9,418 ind/L, and 10,049 ind/L, respectively. The abundance at station five is included in the lightly polluted category with an average phytoplankton abundance of 1,541 ind/L, while station 6 is in the heavily polluted category with the average value of 20,894 ind/L. Species that can be used as indicator species for pollution are those with the highest abundance value, namely Microcystis sp., which indicates that Limboto Lake contains high nitrate and phosphate

DIVERSIFIKASI OLAHAN CUMI KERING “CUMKRING O500” DI DESA OLIMOO’O KECAMATAN BATUDAA PANTAI KABUPATEN GORONTALO

Olimoo’o village as a coastal village has abundant squid potential, so the group of women conducted the processing of dried squid products which are named "Cumkring O500". The problem that arises over time is that the business does not work as expected. The Community Empowerment Learning (KKN PPM) Real Work Lecture Program directs students to apply their knowledge to maximise community empowerment to develop the cumkring potential to become a superior product of the village which leads to an increase in the community's economy. Through this program the transfer of dried squid processing technology is carried out which aims to improve group skills in processing to product marketing, creating diversification of processed dried squid ready and improving the economy of the community. The method used is the active involvement of all group members through group learning techniques accompanied by mentoring and direct practice at all stages of the process. The output of this activity is an increase in group knowledge about the processing of dried squid, the creation of processed squid products with three levels of flavour, namely original, selow and hot issue and product socialisation. The long-term target of this activity is the Cumkring O500 product to become an icon of Olimoo’o Village, as expected by the government and society. Therefore, there needs to be a commitment from the group in cumkring processed innovation and group strengthening to create a sustainable production house, and develop it into Micro, Small, and Medium Enterprises (MSMEs) as a form of independence, equitable economic growth, and increasing community income

Komposisi dan Keanekaragaman Gastropoda Ekosistem Mangrove di Wilayah Pesisir Teluk Tomini sekitar Desa Tabulo Selatan Kecamatan Mananggu Kabupaten Boalemo Provinsi Gorontalo

Penelitian ini bertujuan untuk mengetahui komposisi dan keanekaragaman gastropoda yang berasosiasi dengan ekosistem mangrove di wilayah pesisir Teluk Tomini sekitar Desa Tabulo Selatan Kecamatan Mananggu. Penelitian ini dilaksanakan pada Bulan April sampai Bulan Desember 2014. Metode yang digunakan dalam pengambilan data adalah metode line transek dengan menggunakan kuadran berukuran 1x1 meter.

Penelitian ini bertujuan mengetahui komposisi jenis, kerapatan dan tingkat kemerataan lamun di Desa Otiola Kecamatan Ponelo Kepulauan Kabupaten Gorontalo Utara, yang dilaksanakan pada Bulan Oktober sampai Desember 2013. Metode yang digunakan adalah metode transek dan petak contoh (Transect Plot), dengan menempatkan transek kuadrat ukuran 1 x 1 meter yang dibagi menjadi 25 buah kisi ukuran 20 cm pada hamparan lamun. Setiap transek kuadran ukuran 1 x 1 meter, jumlah tegakan lamun dihitung dalam petak ukuran 20x20 cm dan diambil sebanyak lima kali secara acak sebagai keterwakilan data. Analisis varians (ANOVA) digunakan untuk mengetahui perbedaan antar stasiun pengamatan. Hasil pengamatan, ditemukan 4 jenis lamun di Desa Otiola yang termasuk dalam 2 famili yaitu famili Hydrocharitaceae dengan 3 jenis yaitu Enhalus acoroides, Thalassia hemprichii, dan Halophila ovalis serta famili Potamogetonaceae hanya 1 jenis yaitu Cymodocea rotundata. Tingkat kemerataan tertinggi terdapat pada stasiun 2 dengan nilai indeks kemerataan 0,53 kemudian 0.52 pada stasiun 3 dan 0.50 pada stasiun 1. Tingkat kemerataan di seluruh stasiun masuk dalam ketegori sedang. Kata kunci: Lamun, Komposisi jenis, Kerapatan, Tingkat kemerataa
