Abstract

A study was conducted to identify heavy metals iron or Ferrum (Fe), Cadmium (Cd), and copper or Cuprum (Cu) based on the depth of well water using atomic absorption spectrophotometry method, pH test of water by measuring using digital pH meter and water turbidity using Turbidity meter with NTU (Nephelometric Turbidity Unit) unit in Lamakera Village, East Flores Regency. The purpose of this study was to determine the content of heavy metal elements, pH content and turbidity of the well water. The results showed that the analysis of heavy metal content in well water had the same levels in wells A (10 m), B (25 m), and C (15 m). The levels are Fe < 0.03 mg/L, Cd < 0.0007 mg/L, and Cu < 0.010 mg/L as well as the average pH content in well A on the surface is 6.99 and the base is 6.63. Well B on the surface is 6.34 and the base is 6.29. Well C surface 6.45 and base 6.56. The turbidity of well A at the surface is 0.93 NTU and the bottom is 0.66 NTU. Well B at surface 0.6 NTU and bottom 0.86 NTU. Well C at surface 0.8 NTU and bottom 0.86 NTU.

Abstract

This study investigates the success and vigour of cashew seedlings (Anacardium occidentale L.) through direct seed planting, focusing on its potential to support sustainable land management practices. Using a completely randomised design (CRD), the study applied three treatments: seed coat incision (treatment A), seed coat division (treatment B), and no seed coat treatment (treatment C, control), with each treatment repeated three times, involving 270 seeds in total. The results indicate that the control treatment (C), where seeds were planted intact, led to the highest germination success (97.76%), surpassing the other treatments. This method also resulted in better seedling growth, with superior increases in stem diameter (9.83 cm) and leaf production (3.36 leaves). Additionally, seedlings from the control treatment showed enhanced vigour, with an average height increase of 9.83 cm, indicating the benefits of planting seeds in their natural condition. These findings highlight the importance of direct seed planting in maintaining ecological balance and promoting sustainable agriculture practices. The intact-seed approach is recommended for future cashew planting, as it improves seedling growth, contributes to forest conservation, and reduces vulnerability to pest attacks. Thus, it supports long-term ecological resilience in land management systems.

Abstract

Payment for Environmental Services (PES) is an environmental service compensation activity conducted by Forest Programme IV (FP-IV), designed to be implemented in the Mamasa Sub-Watershed of the Saddang Watershed. The implementation of this PES plan will be collaborated with parties such as the Bakaru Watershed Forum, Hydroelectric power plant (PLTA), and Forest Farmer Groups (KTH) in selected villages over a 5-year contract. However, the challenge is that the target community lacks trust in PES activities and most refuse to join, making the formation of KTH Mappideceng problematic. The purpose of community service is to enhance the capacity of KTH Mappideceng based on the requirements and criteria established by the PES model scheme. The methods used include primary socialization (door-to-door) such as surveys, lectures, and discussions. The results of the community service activities in KTH Mappideceng, Betteng village, showed an increase in the number of members from 12 to 21, with 15 being new members and 6 being existing ones. After the socialization carried out by the team, enthusiasm and motivation to join increased; however, the intervention location and funding limitations were predetermined by the PES model mechanism (FP-IV).

Abstract

Tujuan penelitian ini untuk untuk menentukan efektivitas ekstrak daun ketapang (T. cattapa  L.) sebagai antimikroba pada benih ikan nila. Metode penelitian yang digunakan adalah benih ikan nila yang diperoleh dari Balai Benih Ikan (BBI) Limbung. Benih ikan nila yang digunakan sebanyak 20 ekor/wadah penelitian. Wadah yang digunakan adalah ember plastik berkapasitas 25 liter namun diisi air sebanyak 20 liter. Jumlah wadah penelitian sebanyak 12 buah. Perlakuan yang dicobakan adalah perendaman larutan daun ketapang dengan dosis berbeda terhadap prevalensi dan sintasan benih ikan nila yang terinfeksi parasit. Pada penelitian ini terdapat 4 perlakuan, yaitu dosis 1.000 ppm (perlakuan A), dosis 2.000 ppm (perlakuan B) , dosis 3.000 ppm (perlakuan C), tanpa perendaman larutan daun ketapang (perlakuan D). Hasil penelitian yang dilakukan selama ±1 bulan menunjukkan bahwa prevalensi parasit pada benih ikan nila terendah pada perlakuan C yaitu 50% dengan sintasan 100%. Disarankan untuk melakukan pengujian konsentrasi larutan dengan perbedaan dosis yang lebih kecil antara perlakuan. Hal tersebut bertujuan untuk mengetahui optimasi dosis yang lebih sesuai dalam mencegah dan mengobati penyakit yang disebabkan oleh serangan parasit.
