PPN RU IV Cilacap Successfully Strengthens Community Economy through MAMAKU SIGAP

PT Pertamina Patra Niaga (PPN) Refinery Unit IV Cilacap is continually committed to enhancing the capabilities of communities in the Cilacap area, Central Java, enabling them to manage their environment while living more prosperously. This commitment is realised through a social innovation from PPN RU IV Cilacap in the form of the MAMAKU SIGAP programme.

MAMAKU SIGAP is an acronym for Masyarakat Mandiri Kutawaru Sistem Integrasi Pengelolaan Lingkungan Kawasan Pesisir, which is a Corporate Social and Environmental Responsibility (TJSL) programme from PPN RU IV Cilacap through the empowerment of coastal communities in Kutawaru Ward, Cilacap Regency.

The MAMAKU SIGAP programme was initiated by PPN RU IV Cilacap since 2022, focusing on strengthening the capacity of communities in underdeveloped village areas. Based on social mapping results conducted in 2020 in the Central Cilacap Subdistrict, Kutawaru Ward was identified as an area with high levels of social, economic, and environmental vulnerability.

In response to these conditions, PPN RU IV Cilacap developed the MAMAKU SIGAP programme with the innovation of the Coastal Area Environmental Management Integration System (SIGAP). The programme combines concepts of managing the economy and environment of local commodities through a circular economy approach based on the 9R principle, emphasising multiple commodities and multiple income streams.

It should be noted that this programme focuses on five main pillars: productive coastal areas, coastal management through land restoration and marine aquaculture, crab village tourism, the emergence of culinary tourism and educational tourism based on the environment, Rural Self-Reliance Agriculture Training Centre (P4S), improvements in agriculture and livestock, Amarta Market, building an economic ecosystem for local communities, and Abhipraya Waste Bank, strengthening the circular economy based on waste management.

In practice, MAMAKU SIGAP serves as a container for sorting, collecting, and recycling activities, allowing communities to turn waste into a sustainable source of economic value. In this regard, inorganic waste is channelled to recycling partners and local creative actors, while organic waste is processed into compost used to support agricultural activities and coastal greening.

This process then creates a new economic value chain, where waste becomes a productive resource for improving community welfare. Furthermore, the integration of waste management, community empowerment, and coastal ecosystem conservation has brought about a community-based sustainable environmental management model.

Further, the success of MAMAKU SIGAP is also evident from the economic turnover in the programme, which reaches Rp 366 million per month. In addition, MAMAKU SIGAP has successfully involved approximately 1,500 households in managing social, economic, and environmental growth.

MAMAKU SIGAP also has four sustainability indicators consisting of natural, social, economic, and welfare aspects. From the natural aspect, the programme has successfully managed 7.6 tonnes of waste per year, 8.5 hectares (ha) of mangrove-planted land, 78,300 mangrove seedlings in wellbag and non-wellbag, 5.46 tonnes of carbon dioxide equivalent (CO2eq) per year emission reduction from pallet utilisation, and 877 tonnes CO2eq per year emission reduction from PLTS utilisation.

From the social side, the programme has successfully integrated 5 groups in waste management, created synergy across 6 stakeholders in waste management, given rise to two social culture activities for waste management, and achieved a very good community satisfaction index of 96.8%.

Next, the economic turnover in the market reaches 248 million per month. In detail, Rp 72 million per month comes from income from crab village tourism, Rp 62 million per month from turnover at Amarta Market, Rp 34 million per month from productive coastal income, and Rp 12 million from agricultural and rural cultivation income.

Shifting to the welfare side, the MAMAKU SIGAP programme has successfully created one waste management learning centre. This includes 4 national and international awards for MAMAKU SIGAP, 3 practical guidebooks as a Learning Centre, 10 female members with waste management capacity, and 15 male members with waste management capacity.

On the other hand, PPN RU IV Cilacap also has other flagship programmes, namely the Innovation Programme for Utilising Stripping Gas Overhead 140C-602 in the LNHT ISOM Unit as Boiler Utilities Fuel in Improving Combustion Efficiency, which can save energy by 244,387.79 GJ. In addition, there is the Coke Cleaning Programme on Tip Burner Fuel Gas Using Steam Injection Method Through De-Coking Equipment, which can reduce emissions by 90,398.48 tonnes CO2eq.

There is also the PEPSI ABAH Programme in FOREST (Improving Ammonia and Sulphide Removal Efficiency in Wastewater Through the Use of Fouling-Resistant Tray and Steam Injection Coupling in SWS RFCC), which can reduce ammonia levels in wastewater by 69.32 tonnes of ammonia.

These programmes have led PPN RU IV Cilacap to receive the PROPER Gold award for 2025 from the Ministry of Environment and Forestry. The award was presented directly by the Minister of Environment (BPLH)/Head of the Environment Management Agency (BPLH), Hanif Faisol Nurofiq, to the company representative at the PROPER Environmental Awards event at Taman Mini Indonesia Indah (TMII), Jakarta, on Tuesday (7/4/).

It should be noted that the Company Performance Rating Programme (PROPER) award is held every year as an effort to improve company compliance with environmental regulations.

Area Manager for Communications, Relations & CSR at PT Pertamina Patra Niaga RU IV Cilacap, Agustiawan, explained that as a company targeting and maintaining the Gold ranking, PPN RU IV Cilacap needs to ensure that environmental aspects
