Abstract

Stirofoam sering kita jumpai sebagai sampah yang mencemari badan air. Biota air ada berbagai jenis, salah satunya adalah spirulina yang termasuk jenis mikroalga. Tujuan penelitian adalah menganalisis pertumbuhan spirulina di bawah tekanan stirofoam dan perubahan gugus fungsi stirofoam. Metode penelitian yaitu kultur dilakukan dalam air-tawar (0 ppt) selama 30 hari dan dicek pertumbuhannya melalui kerapatan massa (Optical density) kemudian diuji KruskalWallis menggunakan aplikasi SPSS 25. Stirofoam diuji FTIR. Hasil penelitian menunjukkan laju pertumbuhan tertinggi spirulina pada kultur yang diberi perlakuan stirofoam 150 mg, yaitu sebesar y = 0,0705x. Analisis FTIR menunjukkan telah terjadi perubahan gugus fungsi pada stirofoam yaitu gugus alkohol (-COOH) pada panjang gelombang 3400-3200 cm dan ada rantai siklik yang terbuka (muncul peak pada panjang gelombang 1680-1600 cm). Keberadaan unsur anorganik lain membuktikan spirulina mampu menyerap kontaminan.

Abstract

Biochar is a solid material resulting from biomass carbonization which is generally made through a pyrolysis process, namely the thermal decomposition of biomass under anoxic conditions. Various previous studies have shown that biochar can have multiple positive impacts on soil quality and sugar cane productivity. Biochar can increase plant growth and development through several mechanisms, namely increasing nutrient use efficiency, increasing the amount and availability of nutrients, reducing nutrient leaching and nutrient loss through evaporation, promoting plant growth hormones, and reducing salinity stress. What is interesting is that improving the physical, chemical, and biological quality of soil by biochar allows for reducing the dose of inorganic fertilizer that must be applied to sugarcane. Biochar can be made from various local materials, including unused sugar cane biomass (dry leaves, stem shoots, litter, etc.) and sugar factory waste. Biochar can be applied together with various other materials, such as organic, biological, and inorganic fertilizers to create a more positive synergistic effect on soil quality and plant growth and development. The results of the strength-weakness-opportunity-threat (SWOT) analysis show that the advantages of using biochar based on sugar cane biomass and sugar factory waste, are 1) it is cheap and easy to obtain, 2) contributes to reducing the volume of waste, 3) is one of the carbon sequestration methods effective, and 4) can improve the physical, chemical and biological quality of the soil. The disadvantages are 1) it requires high costs for collection, storage, and transportation to the field and 2) there is high variability in the content of biochar-making materials and soil conditions. Opportunities include the need for farmers to reduce production costs, including fertilizer costs, and increasing awareness of various parties regarding environmental issues, for example about the importance of carbon sequestration and environmentally friendly agriculture. Meanwhile, the threat is that biochar production on a large scale still seems difficult and some farmers still lack confidence or trust in biochar products.. Key-words: biochar, sugarcane biomass, sugar mill waste

Abstract

Cayenne pepper is a leading horticultural commodity in In­donesia. However, the productivity and quality produced have not met market expectations. One of the contributing factors is the low quality of the soil. For this reason, switching from inorganic fertilizers to or­ganic fertilizers, such as Black Soldier Fly Frass (BSFF), is necessary because it can provide several nutrients crucial in improving the soil's physical, chemical, and biological properties. In this study, the formu­lation of BSFF was tested for its impact on cayenne pepper's growth response and yield. The research was arranged in a completely ran­domized design consisting of three treatments with three repetitions, namely P1 (100 grams of BSFF biofertilizer), P2 (250 grams of BSFF biofertilizer), and P3 (500 grams of BSFF biofertilizer). The results showed an interaction between doses of BSFF biofertilizer on plant height, physical conditions (color and size), number, and wet weight of cayenne pepper; which P3 gave the most optimal growth response and yield. In contrast to these results, all treatments reduced vitamin C to the high level of N nutrients in BSFF biofertilizer. Therefore, fur­ther research is needed to find the right dosage (below 100 grams/500 grams of media) so that cayenne pepper has a high vitamin C.

Abstract

Peron Village, located in Limbangan Subdistrict, Kendal Regency, lies on the western slopes of Mount Ungaran and forms part of the Bodri Watershed (DAS Bodri), one of the priority watersheds in Central Java. The village has developed an agroforestry system integrating coffee, sugar palm, and rice fields; however, as an upstream area, the land faces severe ecological pressures in the form of high soil erosion. This erosion threatens to reduce land productivity and increase the risk of flooding in downstream regions. A strategic intervention undertaken is the planting of flamboyant trees (D. regia) and tabebuya trees (T. rosea) as protective and shade vegetation. Both species possess strong root systems and dense canopies, making them effective in reducing erosion rates, enhancing water infiltration, and enriching the aesthetic value of the village landscape. Beyond their ecological functions, flamboyant and tabebuya trees also contribute to the community’s socio-cultural well-being by creating green spaces that foster comfort and strengthen the identity of the agroforestry landscape. Thus, the planting of flamboyant and tabebuya trees in Peron Village serves not only as a measure to mitigate erosion and flooding but also as an integrative strategy for sustaining ecological balance, economic resilience, and social cohesion in the buffer zone of the Bodri Watershed.   Keywords: Bodri Watershed; Agroforestry; Flood Mitigation; Upstream Greening; Landscape Aesthetics

Abstract

The food industry has various potential risks that can affect workplace safety, production smoothness, and product quality. Loso Tofu Factory in Semarang City is a medium-scale industry facing such risks. This study aims to analyze risks in the tofu production process using the Failure Mode and Effect Analysis (FMEA) method and Risk Priority Number (RPN). Among 13 identified risks, five main risks were prioritized for mitigation: slippery production area (R10), soybean spillage due to employee slips caused by slippery areas (R9), tofu crumbling during cutting (R11), mixing of waste with soybeans (R2), and incorrect tofu cutting (R12). Mitigation measures include improving Standard Operating Procedures (SOP), conducting work training, using Personal Protective Equipment (PPE), and maintaining production equipment. The results demonstrate that implementing mitigation strategies can enhance workplace safety, production efficiency, product quality, and ensure industrial sustainability. This research underscores the importance of proactive risk management in maintaining operational continuity and product standards in the food industry. By addressing these prioritized risks, Loso Tofu Factory can minimize disruptions, reduce hazards, and strengthen its position as a sustainable medium-scale enterprise. The integration of FMEA and RPN provides a systematic approach to identifying and managing critical risks, offering a model for similar industries to improve safety and production outcomes.

Abstract

Small and medium-sized industries, particularly the tofu industry, are often characterized by low energy efficiency and high pollution due to a lack of industrial wastewater treatment, leading to direct discharge that degrades water bodies and the surrounding well water quality. This study aims to analyze the quality of well water near the tofu industry in Pakintelan Village, Gunungpati District, Semarang City, to assess its suitability as drinking water. A quantitative descriptive research approach was used with purposive sampling. Data were collected through observation, interviews, and laboratory tests focusing on physical (Odor, Taste, TDS), chemical (pH, Nitrate, Nitrite), and biological (Coliform) parameters from residents' wells. The quality status was determined using the STORET Index method and an ANOVA test, in accordance with the Minister of Health Regulation No. 02 of 2023. The results confirmed that tofu liquid wastewater negatively affects well water quality, and that the distance between the well and the tofu industry significantly influences this water quality. This research contributes to environmental science by providing empirical evidence of the direct contamination pathway from untreated tofu effluent to domestic water sources and highlighting well distance as a critical factor in managing water resources in industrial areas.

Abstract

Indonesia with its abundant natural resources, has long been known as a haven for various types of food crops. One local commodity that deserves attention is sweet potato. Unfortunately, the utilization of sweet potatoes as a staple food or as raw material for the food industry is still not optimal. A socialization and training program on product processing based on village potential was held on July 31, 2024, in Kotakan Village, Karanganyar, Demak. The program aimed to empower the community, especially the women of the Family Welfare Movement (PKK), by optimizing the local potential of purple sweet potatoes into economically valuable products, namely purple sweet potato bakpia. A total of 20 participants, consisting of PKK women, took part in the training. In this event, participants gained knowledge and skills regarding the production process of purple sweet potato bakpia, from raw material preparation to product packaging techniques. Through this training, it is hoped that the community can develop micro-businesses based on local potential, increase family income, and strengthen the village's economic independence. The results of the activity showed high enthusiasm from the participants and the potential for developing purple sweet potato bakpia as a unique culinary icon of the village.
