A collective action approach to rice seed production is an inclusive method involving the community’s active participation at all stages of its execution. This all-inclusive strategy, however, has yet to be thoroughly investigated and published. This study explored how and to what degree an inclusive rice seed business of Gapoktan, based on a collective action approach, might be deployed in a sustainable rice seed company run by community groups. The research comprised the following stages: (1) establishment of a seed production business institution, (2) production of rice seeds, and (3) self-assessment of the performance of the seed production business institution. Institutional data were acquired through a questionnaire that references the European Foundation for Quality Management’s (EFQM) methodology. Three dimensions used were direction (purpose, vision, and strategy; organizational culture and leadership); execution (engaging stakeholders; coasting sustainable value; driving performance transformation); and result (stakeholder perceptions; strategic and operational performance). The study suggests essential findings: The organizational structure of rice seed producers formed is complete regarding its operational functions. The rice seeds produced by Gapoktan have met both the volume and quality standards. From a financial perspective, this rice seed production unit is feasible for further development. However, their social orientation is still relatively high and needs to be more profit-oriented. Uniquely, not all members buy and use Gapoktan seeds. As a result, additional efforts are necessary to provide exceptional service to Gapoktan members.

Fermentation is one of the main processes influencing cacao beans’ quality. Proper post-harvest cacao processing can affect the quality of cacao beans. Spontaneous fermentation of cacao beans is carried out carefully for 5 d to 7 d, characterized by a series of activities of certain microorganisms from three groups of microorganisms: yeasts, lactic acid, and acetic acid. Yeast aims to liquefy the pulp, while lactic acid and acetic acid bacteria play a role in raising and lowering the pH of cacao beans during fermentation. The activity of microorganisms affects the formation of aromatic compounds in fermented cacao beans. During the fermentation process, there is a change in pH and an increase in temperature in the seed heap; this creates conditions that cause changes in the seed’s structure at the cellular level and the metabolites present in the seeds. Leucine, alanine, phenylalanine, and tyrosine are precursors contributing to cacao and chocolate aroma formation. The post-harvest processes affect the yield of cacao beans that will be used in the chocolate industry. Each process must be considered to produce high-quality fermented cacao beans.

Mosquitoes are insects that are detrimental to human health because they act as disease vectors, such as dengue fever. Surabaya was known for its high risk of dengue fever. This study aims to describe the diversity of mosquitoes and breeding site distribution in Eastern Surabaya. The study was conducted in 2021 during the end of the wet season in different habitat types in the eastern Surabaya (residential, city park, bamboo forest, and mangrove forest). Eggs, larval, and adult-stage mosquitoes were collected and stored in the Entomology Laboratory for morphological identification. Adult mosquito was collected by using a sweep net and light trap method, while the larva and egg were collected incidentally from breeding sites. The diversity of mosquitoes in the Eastern Surabaya was determined by using the Shannon-Wiener diversity index (H’), dominance, species richness (R), and breeding site distribution. Eleven species were obtained in this study, namely Aedes aegypti, Aedes albopictus, Aedes annandalei, Anopheles subpictus, Anopheles vagus, Anopheles barbirostris, Culex bitaeniorhynchus, Culex pseudovishnui, Culex quinquefasciatus, Mansonia uniformis, and Malaya genurostris. The H’ index of 1.63 indicates the mosquito community was at a moderate level. The R-value of 1.56 indicates a low level of mosquito species richness. The most abundant species was Cx. quinquefasciatus (37.2%). Most of the breeding sites with mosquito larval infested were found in open areas (79.3%). These numbers mean the total of individuals of each species tends to be low and its dominance shows no effect on other species. The data on mosquito species and their distribution in Surabaya could be used as base information for vector control strategies.

The invasion of nipah (Nypa fructicans) occurred in the Air Telang Protected Forest (ATPF), Indonesia, as a result of mangrove forest degradation caused by anthropogenic activities in the area. This research aims to analyze the distribution of nipah populations in the ATPF and at the same time describe the benefits and potential of nipah both in the ATPF and in various regions in the world. The data collected in this research consists of two types, namely primary data and secondary data. Primary data was obtained through field surveys in the ATPF area, while secondary data was obtained through literature studies of relevant research results. Nipah populations can be widely distributed in degraded mangrove forest ecosystems and invade areas outside their natural habitat because they have high adaptability to the environment, high seed productivity and effective and adaptive seed distribution. Even though the spread of nipah in the ecosystem can hinder the succession of mangrove forests, it turns out that nipah has great benefits for the community and contains important compounds that are useful for making foods, drinks and medicine..
