“…Pemenuhan permintaan cacing nipah saat ini melalui eksploitasi secara masif di habitat asalnya, yaitu daerah muara di dominasi vegetasi nipah (Nypa fruticans). Eksploitasi cacing nipah (N. rhodochorde) secara langsung di habitat asalnya menyebabkan penurunan jumlahnya di alam pada masa yang akan datang (Junardi, 2008).…”

Biodegradation of nipa palm fronds using cellulolytic bacteria on an in-vitro scale was conducted to produce feed for cultivating palm worms (Namalycastis rhodochorde). The spontaneous degradation process is thought to trigger the growth of other microbes from raw materials from unsterilized nypa palm fronds. This research aims to determine the presence of different microbes that participate in the degradation process of palm fronds supplemented with cellulolytic bacterial isolates. The biodegradation process was conducted using dry palm fronds that were not sterilized, without pressurized heat, for 30 days in a sterile container. Cellulolytic bacterial isolates were added to facilitate the process. The research results revealed three characteristics of bacterial colonies with two cell shapes: bacilli and spirals bacterial isolates. The study also identified the presence of protozoa that exhibited morphological similarities to the Ciliophora group. This research provides valuable reports for further studies on the biodegradation process of palm fronds, specifically about ensuring feed safety for cultivating nypa palm worms.

“…Penelitian sebelumnya pada Kawasan Mangrove Sungai Kakap telah dilakukan mengenai karakteristik habitat dan pemanfaatan pelepah nipah (Nypa fructicans) sebagai pakan cacing nipah (Junardi, 2008;Junardi & Riyandi, 2020;Kurniatuhadi el at., 2019), yang menunjukkan adanya peran Annelida serta mikrob pada saat proses dekomposisi pelepah nipah. Berdasarkan hal tersebut komposisi Arthropoda pada proses dekomposisi pelepah nipah penting untuk diketahui, berkaitan dengan peranannya dalam menyediakan substrat.…”

Anthropogenic activities in Nypa palm (Nypa fructicans) forests directly leave a lot of residual nipa fronds, which take longer to decompose. The decomposition process involves decomposer organisms, one of which is Arthropods. Nevertheless, information regarding the composition of decomposition fronds is still limited. This study aims to obtain data and information regarding the composition of Arthropods and their relationship to the decomposition period. Arthropod sampling was carried out by hand collecting methods at 15, 25, 35, and 45 days after placement. The laying of the nipa palm fronds was determined randomly with a vertical position at 20 cm above the ground surface. Arthropod eggs, larvae, pupae, and imago samples were sorted and preserved in 70% Alcohol. Arthropod data obtained were analyzed descriptively. The results showed that the composition of Arthropods consisted of the class Crustacea and Insecta, each with one order (2 genera) and six orders (32 genera). The orders Diptera (Psychoda, Eristalinus) and Amphipoda (Allorchestoides) were dominant. The average number of individuals found increases with the decomposition period. The role of different arthropods influences their composition in the decomposition process of the nipa palm fronds. It is necessary to study the composition of microbes in each decomposition period.

“…Budidaya cacing nipah merupakan objek dari penelitian ini. Menurut Junardi, salinitas air merupakan faktor eksternal dengan unsur kimia yang dapat mempengaruhi tingkat kelangsungan hidup atau sintasan dalam budidaya cacing nipah [3]. Menurut penelitian sebelumnya, selain mengendalikan salinitas air pengunaan pelepah nipah fermentasi sebagai pakan dan tempat hidup cacing nipah dapat meningkatkan sintasan.…”

Nypa palm worm (Namalycastis rhodochorde) is a new species of Polychaeta class found in Sei Kakap area. Apart from being obtained from the river coast, cultivation is one way to get worms, but the cultivation of nypa palm worm is still within the scope of the lab and is done manually. Manual cultivation has a problems, especially in controlling water salinity which affects the survival or survival rate of worm. Therefore, this requires an Internet of Things in installation of worm cultivation. This system aims to control the salinity of the water and then monitor the salinity and temperature of the water as well as the temperature and humidity of the air. Another goal is to control water salinity which affects the survival rate of worms. The results of monitoring and controlling the water salinity will be displayed on a website-based application. Arduino Uno is used as hardware that controls the system, NodeMCU ESP32 is used as a tool to connect to the server, water salinity sensor is used to measure water salinity, DS18B20 sensor is used to measure water temperature, as well as DHT11 sensor is used to measure air temperature and humidity. The results of testing the reading system of each sensor obtained an error value 0,017% and 0,032% water salinity sensors, 0,015% DS18B20 sensor, as well as 0.011% and 0.003% DHT11 sensor. Application of the system can reduce water salinity by 1-3 ppt and resulted in the survival rate of worms by 41%.
