Abstract

Local wisdom has been derived from the expression of ancestors that grows and develops especially in rural life norms which could be related to local food security. The question will be on what kind of natural resources can be managed without damaging the environment. In line with the issue, we need to know the local natural resources and manage it through the people behavior by following the local norms. Margodadi Village located in the western part of Sleman regency. The condition of society and its natural resources and environment is still original and unique. Activities undertaken by the community are mostly simple and traditional. Live harmony between individuals in society still exists. Natural resources and the environment are utilized by the community from generation to generation to this day, such as the existence of clean water - lake which is considered out of a big banyan tree. This water comes out of the ground under the tree and is called “Tuk Sibedug”. The water of this lake is often used for bathe rituals in a pond and the rest flows into the river for farming irrigation especially rice fields. By knowing the inner or spiritual strength of each individual, the norms of life will grow and develop, so that natural resources and environment can be managed better. Natural resources from the agricultural, livestock, fishery and small industries sectors are possible to potentially generate per capita income of 519 kg per person per year. This shows the existence of local food security in the villages of Seyegan that has been achieved.

Abstract

Limbah plastik adalah salah satu sumber pencemaran lingkungan hidup di Indonesia. Plastik merupakan produk serbaguna, ringan, fleksibel, tahan kelembaban, kuat, relatif murah karena berbagai kemudahan tersebut, seluruh dunia bernafsu untuk menghasilkan lebih banyak produk berbahan baku plastik. Namun, tanpa disadari, karakter dasar plastik, ditambah cara penggunaan yang tidak ramah lingkungan, justru merusak lingkungan hidup. Salah satu sampah plastik yang cukup dominan adalah plastik berbahan dasar LDPE (Low Density Polyethylene) dikarenakan plastik berbahan dasar ini memiliki sifat yang tahan terhadap temperature yang cukup tinggi dan memiliki kekentalan yang tinggi. Penelitian ini dilakukan selama 7 hari, pencetakan batako dengan menggunakan alat pencetak manual berukuran (30x15x10)cm. Cetakan diisi dengan total bahan dengan massa 8 kg yang merupakan campuran pasir:semen:LDPE dengan perbandingan 7:1:0, 6,5:1:0,5, 6:1:1, dan 5,5:1:1,5. Pengukuran daya serap air dilakukan pada hari ke-7. Pengukuran kuat tekan batako dilakukan pada hari ke-8. Data hasil penelitian dianalisis dengan metode analisis Rancangan Acak Lengkap (RAL) yang selanjutnya ditabelkan menggunakan tabel annova. Hasil pengukuran berat, daya serap air dan kuat tekan dari semua variasi yang telah di ukur, Penambahan sampah plastik domestik LDPE berpengaruh terhadap kuat tekan batako. Kuat tekan batako rata-rata tertinggi terdapat pada perlakuan A yaitu sebesar 25,952 Kg/cm2 dengan variasi perbandingan pasir:semen:LDPE = 7:1:0. Sedangkan kuat tekan batako rata-rata terendah terdapat pada perlakuan D yaitu sebesar 10,192 Kg/cm2 dengan variasi perbandingan pasir:semen:LDPE = 5,5:1:1,5. Penambahan sampah plastik domestik LDPE berpengaruh terhadap daya serap air batako. Daya serap air batako rata-rata tertinggi terdapat pada perlakuan C yaitu sebesar 9,555% dengan variasi perbandingan pasir:semen:LDPE = 6:1:1. Sedangkan daya serap air batako rata-rata terendah terdapat pada perlakuan A yaitu sebesar 1,389% dengan variasi perbandingan pasir:semen:LDPE = 7:1:0.

Abstract

Domestic wastewater treatment plant (WWTP) sludge still contains organic matter and nutrients, indicating its potential for beneficial reuse. This study aimed to analyse the physicochemical characteristics of dried sludge from Sewon WWTP, Bantul Regency, and to evaluate its potential as a raw material for granular organic fertilizer through physical stabilisation without active composting. Dried sludge obtained from the sludge drying bed was formulated into four treatments: 100% sludge (F1), sludge combined with cattle manure (F2), sludge combined with fermented organic fertilizer mijongan (F3), and sludge combined with rice husk (F4), each at a 1:1 ratio. The processing stages included crushing, mixing, manual granulation using starch as a binder, and laboratory analysis of pH, moisture content, organic carbon, total nitrogen, total phosphorus, total potassium, and C/N ratio, with results compared against national solid organic fertilizer standards. The results showed that all formulations met the requirements for pH and organic carbon content. Variations were observed in moisture content, total nitrogen, and C/N ratio. Total phosphorus and potassium did not meet the minimum standard of ?2% across any of the formulations. The F4 formulation (sludge combined with rice husk) demonstrated the most balanced physicochemical quality, with a moisture content of 7.77%, total nitrogen of 2.15%, and a C/N ratio of 16.96. Overall, Sewon WWTP sludge shows potential as a raw material for granular organic fertilizer; however, further formulation optimisation is required to meet the minimum standards for phosphorus and potassium content.
