Abstract

The study was performed to recognize marketing efficiency on cat fish seed sale from seeder to the drain by demand elasticity approach. Beside it, this study also performed to know most efficiency marketing at exist drains. The study located at Sagaracipta Village Ciparay Sub regency Bandung Regency from August 2006 until September 2006. The research method that used was survey method. Survey method is research method that taking the sample from one population and using the questioner as tool to collect main data. There are 3 main features of survey method in this study, that are data collected from respondent (sample of population) that represented all population, data collected by questioner, generally analysis unit is individual. The study result describes that cat fish seed marketing from seeder to the drain in Sagaracipta was not efficient for the drain. It can seen by demand elasticity rate was larger than 1 (e>1). Among 6 drains that exist, there are 4 drains that has more efficient that others, because their Marginal Revenue (MR) rate were large.

Abstract

A research to find out the toxicity of kolowe seeds on Artemia salina had been done. Crude extract and fractions of kolowe seeds contain saponin, alkaloid, polifenol and triterpenoid. Based on their antibacteria and antifungi activities, kolowe seeds can be used as biopesticide. Toxicity test against to Brine shrimp has been done to know the safety of this biopesticide. The results showed that kolowe seeds extract and fractions had a low toxicity on Artemia salina (LC50 > 30 ppm). In conclusion, kolowe seeds can be an alternative to be used as biopesticide

Abstract

Tourist is one of main component of management in Tanjung Pendam Beach Resort which is oriented to mass tourism as funding source for the continuity of the resort. That’s why, it’s important to know the dynamic of the tourists so it can be determined better form of the management to increase the quality of the services that can impact to the increasing of quantity of the tourists. Methode is used in this research is direct observation with combination of the factually data record and interpretative data record in recording the obserbed data. The data summary of the visitor is recorded most are observed in the working day from Monday to Saturday, the data in a row are : 127, 140, 133, 110, 75, 97 persons. But, on Sunday there are only 65 tourists recorded. The number of ticket sold is most on Sunday, as many as 205 tickets sold. Vehicles that is dominantly used by the tourists to reach the location of the resort is motorcycle with the highest amount is 116 on Sunday. The tourists are prefer to visit in cloudy weather as many as 161 tourist than hot, dark cloudy and rainy weather with the visitors in a row are 102, 104 dan 19 person.

Abstract

Fishery industrial wastewater contents high in nutritional elements especially nitrogen which can be used as an organic fertilizer. In order to increase the effectivity of this wastewater as a fertilizer, the complex substances need to be brokendown become a simpler one. Acetic acid and EM4 (Effective Microorganism 4) is a chemical and biological activator which applied to degradate the complex substances. The objective of research are to study a treatment of fishery industrial wastewater to become an organic fertilizer, and to identify the quality of liquid organic fertilizer resulted when applied to spinach plant (Amaranthus tricolor). Hasil penelitian terhadap kandungan unsur hara awal limbah cair memiliki rata-rata kandungan N total, Total C organik, P tersedia dan K yang dapat dipertukarkan masing-masing adalah 628,10 mg/l; 2115,56 mg/l; 241,1 mg/l dan 246 mg/l dengan nilai pH 6,96. The observation of raw wastewater shows that N total, C organic total, available P and K ionic transfer are 628,10 mg/l; 2115,56 mg/l; 241,1 mg/l dan 246 mg/l orderly with pH value is 6,96. After treatment pH value become 5,2 - 6, 93. Content of C organic total, N total, ratio C/N, nitate, available P and K ionic transfer become 2102,83 – 9622,30 mg/l; 628,10-1064,93 mg/l; 3,69-9,04; 3,0326-4,5123 mg/l, ; 151,77-649,4 mg/l dan 157-548 mg/l orderly. When applied to spinach plant (Amaranthus tricolor) the treatment of the wastewater with activator EM4 give the best result, which has C/N ratio similar to soil, with higher in nitrogen, phosphor and kalium.

Abstract

Nowadays, the chemical ingredients of several additional foods had known as carcinogenic materials. To avoid that, some kind of natural materials are used to be an alternative which it safe and had a lot of important function because of their bioactive essences. Some of them are curcuma ginger and union. This research is done to prove the advantages of using natural additional nutrition from curcuma ginger and union’s essences for African catfish growth performance. The survival and growth performance of African catfish (Clarias gariepinus) fingerlings fed with natural additional nutrition from curcuma ginger and union’s essences raising better than normally nursery. After 45 days rearing period, the percentage fingerling survival for the treatment is 98.33% better than control that only 86.67%. Fingerlings with treatment had the greatest average daily growth, mean body weight, and final average length and was significantly different (p<0.05) from control. Beside of that, the treatment with additional nutrition has undirectly effect to water balance system. This treatment could stabilize the water pH on rearing aquarium.
