The development of society is always related with poverty which happened to half of society. Nowadays, poverty is not only Indonesian problem but also world cases. Indonesia was identically known with its poverty, however deeply inside this country is willingness to develop and grow up. Therefore, to anticipate the increasing of poor society, the government through KKN-PPM opened the opportunity widely to help society by cooperation with university that had qualified human resources. One of them is to help society to improve home industry at target village. It is known that home industry is main role in nation economic that can hold on crisis time. This additional activity helps them to change their life better. This research employed such method to visit the society to be trained, create their groups of home industry, conduct training of good products, labeling, business analysis, business development, exhibition, and study comparative to central industry of Makassar.
Tujuan penelitian ini adalah untuk megetahui pemanfaatan ampas kelapa yang difermentasi cairan rumen dalam pakan terhadap pertumbuhan ikan nila. Penelitian ini dilakasanakan pada bulan September sampai Oktober 2022 di Balai Benih Ikan (BBI) Bontomanai Kecamatan Bontomarannu Kabupaten Gowa, Sulawesi Selatan. Alat dan bahan yang digunakan adalah Rancagan Acak Lengkap (RAL) dengan 4 perlakuan 3 ulagan. Perlakuan A Cairan Rumen (40 ml), Perlakuan B (60 ml), Perlakuan C (80 ml), Perlakuan D (100 ml). Berdasarkan hasil penelitian dapat dilihat bahwa perlakuan dengan kadar ampas kelapa hasil fermentasi cairan rumen yang berbeda dalam pakan diperoleh rata-rata laju pertumbuhan tertinggi pada perlakuan C (80ml) sebesar 3.465, disusul perlakuan B (60ml) sebesar 2.36%, kemudian perlakuan A (40 ml) sebesar 1.68%, dan terendah pada perlakuan D (100ml) sebesar 1.57%. Selanjutnya hasil analisis sidik ragam menunjukkan bahwa perlakuan dengan penambahan kadar ampas kelapa hasil fermentasi cairan rumen tidak berpengaruh nyata (p> 0,05) terhadap laju pertumbuhan benih ikan nila. Hasil analisis ragam ANOVA menunjukan bahwa perlakuan dengan penambahan ampas kelapa hasil fermentasi cairan rumen dalam pakan dengan kadar yang berbeda tidak berpegaruh nyata (p>0,05) terhadap sintasan benih ikan nila. The purpose of this study was to find out the use of fermented coconut dregs in rumen fluid in feed for the growth of tilapia. This research was carried out from September to October 2022 at the Bontomanai Fish Seed Center (BBI), Bontomarannu District, Gowa Regency, South Sulawesi, the tools and materials used is a Completely Randomized Design (CRD) with 4 treatments 3 replications. Treatment A Rumen Fluid (40ml), Treatment B (60ml), Treatment C (80ml), Treatment D (100ml). Based on the results of the study it can be seen that the treatment with different levels of coconut dregs fermented rumen fluid in the feed obtained the highest average growth rate in treatment C (80ml) of 3.465, followed by treatment B (60ml) of 2.36%, then treatment A (40ml)) of 1.68%, and the lowest was in treatment D (100ml) of 1.57%. Furthermore, the results of the analysis of variance showed that treatment with the addition of coconut dregs from fermented rumen liquid had no significant effect (p> 0.05) on the growth rate of tilapia fry. The results of ANOVA analysis of variance showed that treatment with the addition of coconut dregs fermented rumen fluid in feed with different levels had no significant effect (p>0.05) on survival of tilapia fry.
Pengelolaan sumberdaya air sangat penting agar dimanfaatkan secara berkelanjutan dengan tingkat baku mutu yang diinginkan. Salah satu langkah pengelolaan yang dilakukan adalah pemantauan dan interpretasi data kualitas air, mencakup kualitas fisika dan kimia perairan untuk peruntukan budidaya perairan. Penelitian ini bertujuan mengevaluasi lingkungan perairan Teluk Kampe Pasimasunggu untuk kegiatan budidaya ikan dalam karamba jaring apung berdasarkan pengukuran dan pemantauan parameter fisika-kimia perairan. Penelitian dibagi dalam tiga tahapan; yaitu, penentuan stasiun penelitian, pengukuran parameter fisika kimia perairan, dan penentuan metode analisis data. Berdasarkan hasil pengukuran dan analisis beberapa peubah fisika kimia perairan Teluk Kampe Pasimasunggu pada berbagai stasiun terpantau beberapa parameter kualitas air masih dalam rentang yang layak sebagai prasyarat budidaya ikan dalam keramba (KJA), meskipun terdapat stasiun (utamanya L3 dan L4) yang telah mengalami sedikit tekanan dengan tingkat pencemaran sedang (berdasarkan sebaran nilai indeks saprobitas dan Resiprok Indeks Diversity), yang mana beberapa parameter fisika kimia perairan yang kisarannya berbeda dengan kisaran optimum (kedalaman, oksigen terlarut, turbiditas, dan total bahan organik) yang dikhawatirkan bila berlangsung dalam waktu yang lama akan mengarah ke tingkat pencemaran berat. Dismpulkan bahwa Kualitas fisika-kimia perairan Teluk Kampe Pasimasunggu secara umum masih mendukung kehidupan organisme termasuk biota budidaya di sekitar keramba, kecuali stasiun rumah makan/pemukiman dan penambatan perahu (L3 dan L4) terjadi sedikti gangguan. Water resource management is very important so that it is used in a sustainable manner with the desired level of quality standards. One of the management steps taken is the monitoring and interpretation of water quality data, including the physical and chemical quality of waters for aquaculture purposes. This study aims to evaluate the aquatic environment of Kampe Pasimasunggu Bay for fish farming activities in floating net cages based on measurement and monitoring of water physico-chemical parameters. The research is divided into three stages; namely, determination of research stations, measurement of water physicochemical parameters, and determination of data analysis methods. Based on the results of measurements and analysis of several physicochemical variables in Kampe Pasimasunggu waters at various stations, it was observed that several water quality parameters were still within a reasonable range as a prerequisite for fish cultivation in cages (KJA), although there were stations (mainly L3 and L4) that had experienced a slight pressure. with moderate levels of pollution (based on the distribution of the value of the saprobity index and the reciprocal Diversity Index), in which several water physicochemical parameters differ from the optimum range (depth, dissolved oxygen, turbidity, and total organic matter) which are a concern if it lasts for a long time. will lead to heavy pollution levels. It was concluded that the physico-chemical quality of the waters of Kampe Pasimasunggu Bay in general still supports the life of organisms including cultured biota around the cages, except for the restaurant/settlement stations and boat moorings (L3 and L4), with slight disturbances.
One alternative to increase production is to maximize the use of biofloc system cultivation technology. However, the problems in biofloc cultivation are; the difficulty of cultivators to replace or alternatively use commercial bacteria to increase production. One of the efforts made is the use of bacillus sp. The aim of the study was to determine the optimal concentration of bacillus sp that could increase the growth of saline tilapia. This study used a completely randomized design (CRD) with four treatments, each repeated three times, so that there were 12 units. This study tested the concentration of Bacillus sp. 0.0028 ml/L, 0.0030 ml/L, 0.0032 ml/L, and 0.0034 ml/L. The results showed that the highest protein retention was 9.91%, fat retention was 2.05% and the body glycogen content of saline tilapia was 0.68%. This shows that the administration of Bacillus sp. in saline tilapia culture media has a real effect.
