Abstract

Platy fish is freshwater ornamental fish which has beautiful color so it has high aesthetic and economic value, belonging to a type of fish called the “live bearer” or having the ability to give birth. Current problem faced by platy fish farmers are the low production to meet the rising market demand. This causes the lack of ability to reach the desired production target. This research evaluate the effect of giving Oodev through feed to the amount of production of larvae platy fish Xhiphophorus sp. with different dose. The research used completely randomized design with treatment of different Oodev dose which were P1 (0 ml/kg fish), P2 (0,5 ml/kg fish) P3 (1,0 ml/kg fish) and P4 (1,5 Mml/kg fish) each repeated three times. Oodev hormone was given through feed two times a day with feeding rate (FR) 3%. Results showed that the giving of OODEV could raise the number of larvaes produced by female parent with the highest number of 29,33 larvaes on the P3 and lowest treatment as much as 15 larvaes at P1 (P<0,05). The number of larvae produced by the female parent P3 treatment provides the best results with total larvae amount of 176 or average each treatment of 58,76 larvaes.

Abstract

The COVID-19 outbreak is a non-natural disaster and has an impact on learning continuity. This study aimed to find the reality of the continuity/discontinuity of learning of primary education students in East Lombok during student isolation in the prevention of COVID-19. Data obtained through surveys and interviews with 198 respondents representing school principals, teachers, students, parents, and the community. According to the Bayesian Approach to Learning Causal Networks, the data were analyzed descriptively through frequency distribution and causal analysis. It was found that 57.07 % of respondents claimed they did not know the purpose of the isolation policy, so it was not explained. Exactly 54.76 % of respondents admitted to isolation as a holiday, 54 % of respondents admitted to playing to their heart's content during the isolation period, 88.77 % of respondents admitted that this policy was not coordinated, and 100 % of respondents admitted that they did not maximize the function of online learning. The contextual condition of this isolation period is a causal event between a lack of understanding of the policy intent or P (A), causing unclear instructions, or P (B). Unclear teacher instruction or P (B) causes students not to study at home during isolation, or learning discontinuity occurs, with code P (C). Lack of understanding of the intent of the isolation policy, or P (A) causes this policy not to be coordinated with interested parties. Due to unclear instructions, the utilization of online learning, or P (E) is not optimal. The study results are urgent and have implications for the policy of learning from home as well as the coordination pattern of educational stakeholders in the COVID-19 phase.

Abstract

Cupang fish (Betta sp.) are included in the variety of freshwater ornamental fish with attractive and beautiful colors and bodies. However, male betta fish are more desirable. The purpose of this study was to determine the effect of immersing betta fish (Betta sp) broodstock using three different types of honey on the percentage of male fish through broodstock immersion. This study used a completely randomized design (CRD) with 4 treatments and 3 replications, namely P0 (control), P1 (forest honey), P2 (livestock honey), and P3 (mangrove honey), so there were 12 experimental units. Analysis of the percentage of male sex was carried out using analysis of variance (ANOVA) and Duncan's test. The calculation results show that the percentage of male fish in forest honey, livestock honey, and mangrove honey are 76%, 74%, and 92%, respectively. The results of the calculation of the survival rate ranged from 50 – 53%, the fecundity value ranged from 160 – 245 eggs, the hatching rate ranged from 53 – 58%, the absolute weight growth showed a relatively similar value, namely 0.61 – 0.70g, and the weight growth specifically shows a value of 2.84 - 2.90%. The water quality parameter values of temperature, pH and DO obtained during the study were still in optimal conditions for betta fish maintenance. Thus it can be concluded that the treatment using mangrove honey is the treatment with the highest effectiveness value for directing the sex of betta fish (Betta sp) to male.

Abstract

One of the seaweed-producing areas that has considerable potential in West Sumbawa Regency is Kertasari Village and Tua Nanga Village. One type of seaweed cultivated in these two locations is the Kappaphycus alvarezii type. The success of K. alvarezii production activities is largely impacted by the selection of the proper place. The purpose of this study is to assess the performance of seaweed grown using the basic peg method at Kertasari Beach and Nanga Old Beach. This study is an experimental study using a Complete Randomized Design (RAL) with two treatments and 30 replicates. The treatment that was tested was different cultivation locations, namely P1 (Kertasari Beach) and P2 (Nanga Old Beach). Maintenance is carried out for 45 days with the basic staking method and the initial seedling weight is 100 g. The following parameters were measured: absolute weight, specific growth rate, carrageenan randement, biomass production, chlorophyll content, and water quality. The data were examined using the T test with a 95% confidence level. The results showed that cultivating K. alvarezii with basic peg motede for 45 days on Kertasari beach was the best treatment because it increased the absolute weight of K. alvarezii by 45.83 g, the specific growth rate of 0.81%/day, the carrageenan content of 37%, and biomass production of 1.51 kg/m2.

Abstract

Guna menghadapi permasalahan tentang ketersediaan pakan karena peningkatan harga, salah satu upaya yang dapat dilakukan adalah dengan menggunakan pakan alternatif pengganti. Pakan alternatif pengganti yang dapat digunakan adalah dengan memanfaatkan sumberdaya yang ada di sekitar lokasi budidaya. Potensi kelimpahan jenis ikan yang ada di Teluk Ekas dapat digunakan sebagai pakan bagi lobster dengan penangkapan secara langsung menggunakan alat tangkap yang ramah lingkungan. Penggunaan alat tangkap ikan ini diharapkan dapat menunjang ketersediaan pakan selama proses budidaya lobster dan menekan penggunaan pakan buatan. Budidaya lobster di Indonesia masih bergantung pada ikan rucah sebagai pakan utama. Ikan rucah mengandung protein tinggi yang mampu memenuhi kebutuhan protein organisme budidaya untuk mendukung pertumbuhan. Selain itu, harganya terjangkau dan ketersediaannya cukup melimpah. Kelimpahan stok ikan rucah yang tinggi ini belum dimanfaatkan dengan baik oleh para pembudidaya karena keterbatasan alat tangkap yang mendukung, sehingga para pembudidaya hanya mengandalkan hasil tangkapan oleh para nelayan yang setiap hari pergi mencari ikan. Salah satu upaya dalam merespons persoalan untuk mengamankan stock pakan lobster berupa ikan  rucah adalah dengan inovasi teknologi penangkapan ikan menggunakan jaring insang. Para pembudidaya belum memahami bahwa kelimpahan sumberdaya ikan yang ada di sekitar KJA dapat dimanfaatkan sebagai pakan dalam proses budidaya. Kelompok pembudidaya yang tergabung dalam Pokdakkan Pasir Putih diberikan pendampingan melalui penyuluhan dan Focus Group Discussion (FGD) untuk mempelajari, mempraktekkan dan menggunakan jaring insang guna memenuhi stok pakan bagi lobster yang dibudidayakan.

Abstract

Abstract: Sargassum sp. seaweed is included in the category of brown macro algae that has not been cultivated and has not been optimally utilized. Sargassum sp. has economic value because it contains alginate and iodine which are utilized in the food, pharmaceutical, cosmetic, and textile industries. Sargassum sp. has a high carbohydrate content that can be converted into bioethanol and bioenergy. So that this potential can be developed to improve the community's economy and increase efforts to protect the environment from pollution from the use of fossil fuels. Sargassum sp. seaweed can be found in the waters of Gerupuk, Sengkol Village, Pujut District. Gerupuk is a hamlet that is included in the Mandalika Creative Economic Zone, among the community's livelihood activities is seaweed cultivation. Seaweed farmers in Gerupuk only cultivate K. alvarezii seaweed. They only know Sargassum sp. as a seaweed that grows wild and has no economic value. Sargassum sp. in Gerupuk is not utilized, so it needs to be educated on its benefits and utilization. This community service activity will be carried out in Gerupuk Hamlet, Sengkol Village, Pujut District, Central Lombok Regency. The output targets of this community service activity are appropriate technology for the cultivation of Sargassum sp. for bioethanol production, publications at national community service seminars and articles published in national community service journals indexed by sinta. The stages of implementing this activity are coordination of activities, counseling, demonstration of Sargassum sp. seaweed cultivation, mentoring, evaluation of activities, and collaboration with the Lombok Marine Aquaculture Center (BPBL). The expected results of this activity are that seaweed farmers in Gerupuk can cultivate Sargassum sp. to improve the household economy and the community economy. Keywords: Seaweed, Sargassum sp., cultivation, bioenergy, bioethanol.
