The problem of fertilizers is often a factor inhibiting agricultural development. This is due to, among other things, the relatively high price of fertilizers, limited supply, decreasing type and quality, which makes it difficult for farmers to obtain fertilizers according to their needs. An alternative to anticipating and overcoming fertilizer shortages is that farmers are encouraged to use organic fertilizers or compost. Based on these considerations, outreach activities to farmers and direct training have been carried out in August-October 2020 in Kwala Bingai Village, Stabat District, Langkat Regency, Sumatera Utara Province. The results obtained are that these activities provide many benefits to farmers such as utilizing agricultural waste for making organic fertilizers so that they are not wasted and can overcome fertilizer scarcity and high fertilizer prices by making simple organic fertilizers. and this activity should be done frequently so that agricultural waste can be utilized.

Teluk Palabuhanratu memiliki banyak sumberdaya ikan, salah satunya adalah ikan kurau Polynemus dubius. Aktivitas penangkapan ikan yang terus-menerus dapat mempengaruhi dinamika populasi ikan kurau. Perubahan dinamika populasi dapat diketahui dengan melihat struktur ukuran dan reproduksi ikan. Tujuan penelitian ini adalah untuk menganalisis status populasi ikan kurau P. dubius di Teluk Palabuhanratu melalui pengkajian aspek reproduksi dan dinamika populasi selama bulan Mei-September 2017. Jumlah ikan kurau diperoleh sebanyak 384 ekor ikan jantan dan 556 ekor ikan betina dengan menggunakan metode Penarikan Contoh Acak Berlapis (PCAB). Analisis data terdiri atas sebaran frekuensi panjang, hubungan panjang bobot, serta rasio kelamin dan tingkat kematangan gonad. Hasil penelitiaan diperoleh bahwa rasio kelamin jantan dan betina adalah 1:1,45 (tidak seimbang), tingkat kematangan gonad IV terjadi pada bulan september sebesar 68% jantan dan 38% betina. Hubungan panjang bobot ikan kurau memiliki pola pertumbuhan isometrik didominasi oleh ikan belum matang gonad. Oleh karena itu, status populasi ikan kurau di Palabuhanratu sudah menunjukan overexploited dengan aspek reproduksi yang menunjukkan kondisi TKG yang tidak ideal, nilai Lc<Lm dan menangkap pada musim pemijahan akan mengganggu keberlanjutan populasi ikan ini sedangkan dari sisi dinamika populasi, pertumbuhan ikan yang seragam menunjukkan potensi pertumbuhan ikan semakin rendah dan perlu kehati-hatian dalam menetapkan target tangkapan.

Length Weight Relationship and Reproduction Potential of Eastern Paradise Fish Polynemus dubius in Palabuhanratu Bay: Hubungan Panjang Bobot dan Potensi Reproduksi Ikan Kurau (Polynemus dubius Bleeker, 1853) di Teluk Palabuhanratu Julia Syahriani Hasibuan; Mennofatria Boer; Yunizar Ernawati

Ikan kurau (Polynemus dubius) merupakan salah satu ikan demersal yang ditangkap oleh nelayan di perairan palabuanratu. Informasi biologi reproduksi P. dubius ini masih sedikit sehingga diperlukan kajian reproduksi bagi pengelolaan di masa mendatang. Penelitian tentang aspek biologi meliputi hubungan panjang bobot, nisbah kelamin, tingkat kematangan gonad, indeks kematangan gonad, fekunditas dan diameter telur dilakukan pada bulan Mei sampai dengan September 2017. Hasil penelitian menunjukkan bahwa hubungan panjang – bobot ikan kurau mengikuti persamaan W = 0,0000051531L3,0779, dengan nilai b = 3. Dengan demikian ikan kurau mempunyai pola pertumbuhan yang isometrik dimana terdapat keseimbangan antara pertumbuhan panjang dengan pertumbuhan bobot. Proporsi ikan kurau betina lebih dominan dibandingkan proporsi ikan kurau jantan selama penelitian. Proses kematangan gonad terjadi secara bertahap dan mengalami pemijahan secara tidak serentak (partial spawning). Fekunditas ikan kurau berkisar antara 1.027 – 18.580 butir dengan indeks kematangan gonad antara 2,172% - 7,027%.

Segara Anakan lagoon was water located in the estuary between Ciamis regency and Cilacap regency. The purpose of this research is to observe sex ratio, the maturity level of gonad, and the gonad maturity index of Moolgarda sp. Sampling was conducted for three months, from March to May 2017. The method used is a simple random sampling method. The results of research that the sex ratio of Moolgarda sp. male is higher than female. The gonad maturity level of Moolgarda sp. was obtained from levels I, II, III, and IV. The Gonad Maturity Index value Moolgarda sp. males ranged from 0.0022% - 1.3041% while GMI Moolgarda sp. female 0.0424% - 5.5827% with a fecundity of Moolgarda sp. from 7356 - 131350 eggs.

Traditional fishermen in Dusun XI, Percut Village, Deli Serdang Regency, North Sumatra Province, using rawai fishing gear, nets, and hand line instead of other technological gear. Sea tides also influence fisherman's ability to get out of sea; when the river mouth reaches high tides, fishermen will go to sea; when the river mouth recedes, fishermen can not go to sea. Fishermen are frequently returned to sea with little results, especially in the absence of technological application. Education is important, and advances in fish finder technology can help fishermen catch more fish by making it easier to use. The implementation method is theoretical and practical, with the formation of an actually trying to implement committee team occurrence through educational methods with theoretical media attention, as well as practical activities such as fisherman group discussions and joint operation demonstration activities in the field. Fishermen in Dusun XI, Percut Village, Deli Serdang Regency benefit significantly from using a fishfinder tool and helping in increasing fish catches, according to data monitoring and assessment.
