Abstract

Insect larvae, such as black soldier fly larvae (BSFL: Hermetia illucens) are currently being considered as an alternative source of protein for poultry and aquaculture industry while in the same time apply as agent to manage organic wastes. In order to achieve both roles it is necessary to develop an appropriate farming methodology and understand the impact of different feeding source for the insect production. The study explored the effect of three local plant based organic wastes as feedstocks to growth of the black soldier fly larvae. Separate feeding trials on horse manure (HM), vegetable wastes (VW), and tofu dreg (TD) was done and their effect on BSF larvae growth rate, larvae weight and total prepupal yield in grams content analysed. The efficiency of the BSF larvae to consume and ability to reduce the waste load of the different substrates was also evaluated. The result showed all materials suitable as feeding material for black soldier fly. Difference on physical properties and chemical content affected the development time, harvested biomass, efficiency of digestivity, and efficiency of biomass production which is unique for each type of waste. This study provide base line information for future development of plant based organic waste management.

Abstract

Environmental conditions and fish stocking density in tilapia cultivation (Oreochromis niloticus) are important factors in determining the success of the cultivation process and supporting optimal fish growth. This study used four treatments, namely A, B, C, and D, for 3, 5, 7, and 9 fish, respectively. The purpose of this study was to determine the effect of raccoon tail plants (Ceratophyllum demersum) and genjer plants (Limnocharis flava) on tilapia mortality, determine the ratio of feed conversion and the effect on ammonia concentrations, determine the effect of ammonia concentrations on the productivity of genjer plants, determine the warning system modeling on ammonia concentrations, as well as calculate mass and energy balance in the cultivation system of tilapia and genjer. The result is that the planting of raccoon tails and genjer in the system significantly affects tilapia mortality. The average value of feed conversion ratio from treatments A, B, C, and D were 1.75; 1.36; 3.51; and 2.87, respectively. The effect is significant and directly proportional to ammonia concentration and genjer productivity. The ammonia warning system modeling is in the form of linear equations, namely y = 0.2085x - 0.0193 with R2 = 0.9692. This system's balance of mass and energy can be divided into three subsystems, namely, fish acclimatization, fish cultivation, and genjer cultivation. Keywords: ammonia, genjer, modelling, tilapia

Abstract

Black soldier fly (BSF) (Hermetia illucens) is an insect spe-cies utilized as the converter of organic wastes into biomass applicable as a potential replacement of protein and lipid sources of animal feed and other industrial use. The limiting factor for the sus-tainability of this activity is the number of eggs produced as all processes started from the egg. Variable of quality of the substrate eaten during the larval stage and the proportion of males and fe-males are among the decisive factors for egg production. The pur-poses of this study were to understand the impact of the substrate to the production of a particular sex, to developed a simple method by comparing the weight and size of the pupae to distinguished between male and female, and to find the best sex ratio to produce the highest number of eggs. In this study, two types of substrates (balance proportion of macronutrient and high in protein and lipid were applied as feeding material for larvae. The weight and length of each pupa produced were measured and the pupae kept inside separated containers to find the morphological differences between male and female pupae. Adult insects produced from pupae then used for study on the effect of sex ratio on reproduction success. The adults kept inside 1 x 1 x 1 m screen cages with 3 groups of sex ratio (male : female) which were 50%:50% (P1), 60%:40% (P2), and 40%:60% (P3). The probability of sex was analyzed by logistic regression while the number of eggs estimated by the weight of the egg batch. The result showed substrate used in this study is not affect the sex ratio of adult flies, weight of pupae as the best predictor for sex of the adult flies, and the best ratio of male and female for egg production was 40:60.

Abstract

Quail has a high reproductive ability, which can reach 3 to 4 generations a year. The quail also have high eggs productivity and capable of producing 250-300 eggs/quail/year. Egg production is closely related to the reproductive system and feed. It is necessary to know the effect of feeding fermented kangkong on the characteristics and histology of the quail reproductive organs. The increase in livestock population should be balanced with an increase in the availability of feed. Kangkong seeds waste (Ipomoea reptans Poir.) is rejected seeds from seed factories that have the potential to become alternative feed ingredients because it contains about 13.46% protein. The purpose of this study was to determine the effect of fermented kangkong seed feed (Bikafer) on the characteristics of reproductive tract organs and histology of quail oviducts because feeds affect the development of the reproductive tract and quail egg production.  This study used a completely randomized design method (CRD) with 5 treatments and 4 replications. The treatments were as follows: R0 = commercial feed, R1 = 0%  (Bikafer), R2 = 7.5% (Bikafer), R3 = 15% (Bikafer) ,R4 = 22.5% (Bikafer). Data were analyzed using one-way ANOVA with a significance level of 95% (α = 0.05) and the Kruskal-Wallis test, while histological observations were described descriptively. The results showed that there were significant differences in the characteristics of the uterus, vaginal length, and isthmus weights. The histology of the quail reproductive tract developed well and showed the tunica mucosal tissue, serous tunica, muscular tunica, goblet cells, epithelium, and tubular gland cells.

Abstract

  Global warming has been reported in last decades. Chang-es in average Earth’s temperature may affect the physiology of many insect species, especially the ones which act as a human disease vec-tor, like Aedes aegypti. In this study, the effect of increasing water temperature on physiological components related to development period, sex ratio, and body size of two distinctively strains, VCRU (Vector Control Research Unit) and Pangandaran. Thirty larvae of each strain kept inside distilled water with the temperature of 25°C, 27°C, 30°C, 33°C, 35°C, 40°C which replicated three times. Observa-tions were conducted until all larvae metamorphed into adults or all larvae dead. Development rate and time were analyzed by frequency dependent mean. The result showed that the optimum temperature for larvae development of VCRU strain was 27-30°C with a survival rate of 84% while it was 30°C for Pangandaran strain, with the surviv-al rate of 83%. Larvae of both strains showed 100% mortality rate when kept inside a container with water temperature exceed 33°C. Both strains showed the highest and the lowest male:female ratio at similar water temperature which were 33°C and 30°C, respec-tivelly. Highest and lowest ratio of VCRU was 1.25 and 0.6, respec-tively, while it was 1.4 and 0.6 for Pangandaran. In general, larvae lived in increasing water temperature showed reducing wing width.

Abstract

Black Soldier Fly Larvae (BSFL), Hermetia illucens (Diptera: Stratiomyidae) are widely used as bioconverter agents for various organics waste, and BSF pupae are often used as fodder for poultry and fish, because the BSF pupae have a high protein content. This study focused on applying BSFL as a bioconversion agent of the fermented barley waste to convert it to larvae biomass. Prior to application, barley waste was fermented either using effective microorganisms-4 (EM4), leachate, and water for seven days. The fermented barley waste was applied as feeding material for BSFL at the rate of 100 mg/larvae/days. As control commercial chicken fed (CF) was applied as feeding material at a similar feeding rate. During this study, waste reduction index (WRI), and efficiency of digested feed (ECD) were calculated, and the protein content in the BSF prepupae was analyzed. The results of this study showed that BSFL fed with CF produces the shortest development time (27 days), and high consumption rate. BSFL fed with barley waste fermented with EM4 (BE) and Leachate (BL) produces a larval period of 31 and 30 days respectively, and statistically those were not significantly different from control. This study showed that treatments of BE and BL, produced a very high larval survival rates, 98.67% and 97.00% respectively, and those two treatments were not statistically different from the control (96.67%). Although the control treatment resulted in a higher WRI compared to the other treatments, but the ECD of BE and BL treatments were higher than the ECD of the control. From this study, it can be concluded that BSFL has a good ability to convert fermented barley waste as well as controls, and the prepupae has a high protein content (42%), so BSFL fed with fermented barley waste has the opportunity to be used as a fed for poultry and fish.

Abstract

Lalat tentara hitam atau black soldier fly (BSF), Hermetia illucens (Diptera: Stratiomyidae) telah banyak dimanfaatkan sebagai agen biokonversi berbagai limbah organik. H. illucens telah banyak dimanfaatkan sebagai pakan hewan ternak unggas dan ikan, karena memiliki kandungan protein yang tinggi. Tujuan penelitian ini adalah untuk mengetahui potensi reproduksi BSF yang diberi pakan limbah kulit pisang. Penelitian dilakukan di laboratorium pada kisaran suhu 18-28℃, kelembaban relatif 55-90%, dan periode waktu pencahayaan 12:12 jam terang:gelap. Larva BSF diberi pakan limbah kulit pisang dan pakan ayam komersil sebagai kontrol. Data mortalitas dan periode hidup setiap stadia, rasio kelamin, dan fekunditas dianalisis berdasarkan perhitungan tabel hidup. Hasil penelitian menunjukkan bahwa laju pertambahan intrinsik (r) adalah 0,073 dan 0,106  per hari, laju kenaikan terbatas (λ) adalah 1,080 dan 1,112 per hari, laju reproduksi bersih (R0) adalah 52,57 dan 118,40 keturunan, serta waktu generasi rata-rata (T) adalah 50,85 dan 44,75 hari, masing-masing pada limbah kulit pisang dan pakan ayam.  Hasil penelitian menunjukkan bahwa H. illucens yang diberi pakan ayam memiliki parameter reproduksi yang lebih baik daripada limbah kulit pisang. Walaupun demikian, penelitian ini menunjukkan bahwa BSF dapat digunakan sebagai biokonverter limbah kulit pisang.

Abstract

Larva lalat tentara hitam (LLTH) (Hermetia illucens) dapat mengonsumsi berbagai limbah organik untuk menghasilkan biomassa yang kaya akan kandungan protein dan lemak. Tujuan dari penelitian ini adalah menguji dari aplikasi LLTH pada produk pangan olahan yang sudah kedaluwarsa, hal yang relatif belum banyak diteliti di Indonesia terutama terkait dengan pertumbuhan dan perkembangan dari LLTH. Produk yang diujikan adalah susu bubuk instan dengan pakan ayam komersial sebagai kontrol dan alpukat sebagai pembanding produk yang umum digunakan sebagai pakan LLTH. Pada penelitian ini, 200 ekor larva berusia 7 hari menjadi sampel uji pada tiga kelompok tersebut. Pakan diberikan setiap 3 hari (200 mg/larva/hari) hingga 50% dari larva telah bermetamorfosis menjadi prepupa. Pengambilan data terkait berat tubuh dan tingkat kematian dilakukan bersamaan dengan waktu penggantian pakan. Saat prepupa bermetamorfosis menjadi pupa, setiap individu ditempatkan pada botol vial terpisah untuk proses identifikasi jenis kelamin dan masa hidup. Data pada kelompok susu kedaluwarsa dan kontrol menunjukkan rata-rata berat akhir larva lebih tinggi (0,11 gram berbanding 0,12 gram), proporsi lalat dewasa yang lebih banyak betina (♂:♀, 90:94 dan 90:98), waktu pertumbuhan larva hingga pupa lebih singkat (keduanya memiliki waktu yang sama yaitu 34 hari), dan total masa hidup lalat lebih pendek (57,3 hari berbanding 54,8 hari) lebih baik dibandingkan kelompok alpukat. Sementara itu, kelulushidupan larva tertinggi tercatat pada kelompok kontrol diikuti dengan kelompok yang mendapatkan pakan alpukat (98,5%) dan susu kedaluwarsa (96,5%). Berdasarkan hasil ini dapat disimpulkan bahwa susu kedaluwarsa dapat digunakan sebagai pengganti pakan ayam dalam pengembangan sistem produksi larva BSF yang lebih berkesinambungan
