Abstract

Poecilia sp. is one type of ornamental fish that has distinctive characteristics because molly fish are freshwater ornamental fish that are able to live and breed in saline (brackish water) environments. Induction of molly fish spawning can be done with salinity treatment on the spawning media because the endocrine system in molly fish which plays a role in regulating body balance against changes in environmental conditions, especially changes in salinity will become more active so that it affects metabolism and reproduction (Taufik & Kusrini, 2006). The purpose of this study was to analyze differences in salinity as a spawning stimulant in molly fish. the method used in this study: P1. Salinity 10 ppt, P2. Salinity 15 ppt, P3. salinity 20 ppt, P4. Salinity 25 ppt, P5. 30 ppt with three replications. Parameters observed were Gonad Maturity Level (TKG), Gonad Maturity Index (IKG), survival rate (SR), and gestation period. The reared fish showed good gonad maturity so that spawning occurred. The results of this study, the highest gonadal maturity level was found at P1 salinity 10 ppt and P2 salinity 15 ppt the best, namely TKG V compared to P3, P4, and P5 namely TKG IV. The best gonadal maturity index was treatment P1 which was 14.28±2.0c followed by P2 11.71±2.0bc, P3 10.74±0.76abc P5 8.01±2.34ab and P4 7.27±2, 84a. The fastest gestation period was in P1 and P2, namely 44 days and 23 days. The highest survival rate occurred in P1 and P2, which was 100%. The highest absolute weight average was found in P1 which was 8.01±0.82c P2 6.33±0.5bc. The conclusion of this study, different salinity has a significant effect on the gonadal maturity index and absolute weight of golden black molly fish.

Abstract

Oil palm is one of Indonesia’s key plantation commodities, producing edible oil, industrial oil, and biofuel (biodiesel) and contributing positively to economic and social development. This study aimed to: (1) analyze land suitability for oil palm in Ranah Batahan Subdistrict using fuzzy logic; and (2) determine oil palm productivity levels in Ranah Batahan Subdistrict. Land suitability analysis was conducted using a fuzzy logic approach to the area’s biophysical conditions, while oil palm productivity data were obtained from the Central Bureau of Statistics (BPS) of Ranah Batahan Subdistrict. The results show that, based on land suitability analysis using fuzzy logic, land for oil palm cultivation in Ranah Batahan Subdistrict is classified into two categories: moderately suitable and highly suitable. The area categorized as moderately suitable covers 12,420.53 hectares (43.17%), whereas the highly suitable area extends over 17,174.79 hectares (56.83%) of the total area of Ranah Batahan Subdistrict. Oil palm production data indicate that Nagari Batahan Selatan is the nagari with the highest oil palm production, reaching 50 tons, while the lowest production is found in Nagari Desa Baru, at 10 tons. These findings confirm that most of Ranah Batahan Subdistrict has a high level of land suitability for oil palm development, while also revealing inter-nagari variation in productivity that is important to consider in planning and managing local oil palm development.
