Abstract

Resources of fossil fuel continue to decrease and cannot be renewed so that replacement alternative is needed. Biofuels (biodiesel) become one of the alternatives because it can be renewed and environmentally friendly. First-generation biodiesel from food sources and second generation of food waste can disrupt the availability of food. Those are inefficient because it requires extensive land for its provider. Seed of nyamplung (Callophylum inophyllum) is very potential as biodiesel raw material because of its oil content 40-70% is high compared to other types of plants, such as jatropha range of 40-60% and palm of 46-54%, raw materials saving and having twice of fuel as much as kerosene. The general purpose of this research is to produce third generation biodiesel from nyamplung  as material to overcome fossil fuel crisis especially for fishermen and farmers in coastal area of Brebes Regency and surrounding areas. To be able to achieve the goal / general target is done by assessing oil content in nyamplung seed, biodiesel synthesis, intensive culture techniques and models of development of mass culture. The biodiesel yield produced from nyamplung seed oil in this study was 82.87%, in the range of biodiesel yields of previous researchers through a single stage transesterification of 79.03-91,00%. Cetana number and alkyl ester figures in the resulting biodiesel respectively 79.5 and 99.71% have met the Indonesian National Standard (SNI). The resulting density was 893.1 kg / m3, fog point  was 20oC and total glycerol  was 0.26%, was approaching the SNI by an insignificant difference, while the acid number generated was 1.86 mg KOH/gr of biodiesel and the biodiesel viscosity was 15.7 mm2 /s has not fulfilled the SNI significantly. To improve the number of acids and viscosity is still needed refinement biodiesel synthesis process through the diversification of the number of esterification stages, alternative types and catalytic levels or optimization of transesterification reaction temperature.

Abstract

Ponds in Indonesia, especially in Brebes district, usually produce export-oriented fishery products that have high economic value. One of the fishery products currently being developed is vannamei shrimp (Litopenaeus vannamei). The presence of plankton in the water can be used as an indicator of water quality because it is strongly influenced by water quality. The purpose of this study was to estimate the abundance and stability of pond water from biological measurements (variation, diversity, and dominance of plankton) in the Sawojajar vannamei shrimp ponds. The method used is quantitative and descriptive at random. The results showed that the value of the abundance of phytoplankton ranged from 3451 to 6895 cells/mL, with the highest relative abundance being the type of Bacillariophyta. Meanwhile, the abundance of zooplankton ranged from 45 to 525 ind/mL, with Rotifera having the highest relative abundance. The diversity index status (H') is moderate, the uniformity index (E) is high, and the dominance index is low. Phosphate and COD found were high, as were other water qualities such as DO and temperature. Optimum pH, salinity, and brightness

Abstract

Ikan nila (Oreochromis niloticus) merupakan salah satu komoditas perikanan yang digemari masyarakat dalam memenuhi kebutuhan protein hewani karena memiliki daging yang tebal serta rasa yang enak. Ikan nila juga merupakan ikan primadona ekspor yang terus meningkat dibuktikan dengan jumlah permintaan yang terus meningkat tiap tahunnya. Dalam upaya untuk meningkatkan produksi ikan nila, maka perlu dilakukan pengujian Media air yang sesuai dengan kebutuhan ikan nila agar dapat meningkatkan pertumbuhan ikan nila (Oreochromis niloticus). Penelitian ini bertujuan untuk mengetahui media air yang lebih baik antara air hujan atau air tawar terhadap tingkat pertumbuhan ikan nila (Oreochromis niloticus). Metode yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) dengan dua perlakuan yang berbeda, 3 kali ulangan. Variabel perubahan adalah variabel air hujan, air tawar dan kontrol yaitu: Perlakuan A1 (air tawar yang difilter), A2 (air hujan yang di filter), K1 (kontrol 1, air tawar yang tidak di filter) dan K2 (kontrol 2, air hujan yang tidak di filter). Kualitas air dalam hubungannya dengan parameter fisika (suhu dan oksigen terlarut) serta parameter kimia (pH, salinitas, Ca, Mg, CO3, HCO3, PO4, NO2, amonia dan TOM). Hasil penelitian menunjukan bahwa tingkat pertumbuhan ikan nila (Oreochromis niloticus) yang dipelihara pada media air hujan tidak berbeda nyata (P ˃ 0,05) dengan yang dipelihara pada air tawar.   Tilapia (Oreochromis niloticus) is one of the fishery commodities that is popular with the public to meet their animal protein needs because it has thick flesh and a delicious taste. Tilapia is also a favorite export fish which continues to increase as evidenced by the number of requests which continues to increase every year. In an effort to increase tilapia production, it is necessary to test suitable and good water media in order to increase the growth of tilapia (Oreochromis niloticus). This research aims to determine which water medium is better, rainwater or freshwater, on the growth rate of tilapia (Oreochromis niloticus). The method used in this research was a Completely Randomized Design (CRD) with two different treatments, 3 repetitions. The change variables were rainwater, freshwater and control variables, namely: Treatment A1 (filtered freshwater), A2 (filtered rainwater), K1 (control 1, unfiltered freshwater) and K2 (control 2, water unfiltered rain). Water quality in relation to physical parameters (temperature and dissolved oxygen) and chemical parameters (pH, salinity, Ca, Mg, CO3, HCO3, PO4, NO2, ammonia and TOM). The results of the study showed that the growth rate of tilapia (Oreochromis niloticus) kept in rainwater was not significantly different (P ˃ 0.05) from that kept in fresh water.
