Abstract

High ambient temperatures inside tropical greenhouses can significantly raise nutrient solution temperatures in vertical hydroponic systems, disrupting nutrient uptake and reducing plant productivity. This study focuses on the design and development of a nutrient cooling system (chiller) using two TEC1-12706 thermoelectric modules (Peltier) arranged in series to enhance heat dissipation performance. The nutrient solution is pumped from the reservoir to the cooling chamber using a 12 V DC pump and recirculated in a closed-loop configuration. The chiller system is fully automated, controlled by two DH48S digital timers operating simultaneously: one activates Peltier 1, while the other controls Peltier 2 via the NC output (5 minutes) and the pump via the NO output (30 seconds), enabling alternating programmed cooling and circulation. The entire chiller unit is active only from 08:00 to 18:00 WITA using a KG316T programmable timer, corresponding to peak thermal stress hours inside the greenhouse. Results showed that despite greenhouse temperatures reaching up to 39.4 °C with relative humidity dropping to 47.6%, the chiller system maintained nutrient solution temperatures within the optimal 27–30 °C range. This design proved effective in reducing and stabilizing nutrient temperature under high heat microclimates. With its simple, automated, and energy-efficient architecture, the chiller system offers a promising solution for small-scale vertical hydroponics and greenhouse-based urban farming in tropical regions.

Abstract

The integration of poultry farming and maggot cultivation was carried out with the Tui Jati Livestock Farmers Group in Central Lombok Regency to enhance farmers' skills in managing poultry waste, maggot cultivation, and improving poultry feed efficiency. The main challenges were the environmental pollution caused by poultry waste and the high cost of feed, which negatively impacts farmers' economy. The program aimed to assist in processing poultry waste into a medium for maggot farming, offering an efficient and sustainable alternative feed, reducing dependence on expensive commercial feed, and mitigating environmental pollution. The program also designed an integrated system for poultry and maggot farming through a processing facility and provided training on poultry waste management and maggot cultivation techniques. The methods included initial observation and mapping of conditions, thematic training on maggot egg hatching and cultivation, hands-on field guidance, and evaluation through pre-tests, post-tests, observations, and interviews. Evaluation results showed an improvement in farmers' knowledge and skills, with average scores rising to a "good" category on the Likert scale. Farmers successfully cultivated maggots independently, from egg hatching to the laying phase, using poultry waste as a medium in the Maggot Center. In conclusion, the integration of maggot farming in poultry production contributed significantly to reducing environmental pollution and improving farmers' economies. The success of the program was largely due to the active participation of the Tui Jati Livestock Farmers Group at every stage of implementation. Achievements include increased knowledge and skills in maggot farming and the creation of new economic opportunities that support sustainable livestock farming and improve community welfare

Abstract

The success rate in the seedling process is ofte hampered by inappropriate watering, which can cause the seedlings to rot and die. To overcome this problem, an efficient watering system with a high degree of precision is required. Mist irrigation is one of the appropriate methods because micro-sized water droplets are sprayed to maintain air humidity and reduce the rate of transpiration. This study aims to optimize the application of mist irrigation by evaluating the effect of nozzle height variations on plant growth. Using an experimental method, the variations included nozzle heights of 20 cm, 25 cm, and 30 cm. The parameters measured in this study included water discharge, plant height, number of leaves, and leaf area. The results showed that a watering height of 25 cm produced the best plant growth. The results of this study show that specific adjustment of the nozzle height is very important for improving the efficiency of mist irrigation in the seedling process.

Abstract

Seledri atau Apium graveolens sudah sangat dikenal pemanfaatannya oleh masyarakat luas. Daun tanaman tersebut dikonsumsi sebagai lalapan dan penghias hidangan. Bijinya juga dapat dimanfaatkan sebagai bahan penyedap. Selain itu, ekstrak minyak seledri juga dapat digunakan sebagai obat.Penanaman seledri di areal lahan terbuka mengalami beberapa kendala diantaranya seledri merupakan varietas tanaman semusim yang sensitif terhadap kebutuhan air yang memiliki kondisi jenuh air dan kurang air. Pemberian air yang berlebihan atau kekurangan dapat membuat pertumbuhan tanaman seledri tidak optimal. Penerapan mikrokontroler pada sistem irigasi dapat memungkinkan dalam mengontrol pemberian air secara otomatis berdasarkan perintah yang diberikan. Selain masalah pemberian air, Perubahan iklim, suhu ekstrem, atau cuaca tidak stabil juga menjadi kendala tanaman seledri di lahan. Seledri lebih baik tumbuh pada suhu yang lebih sejuk, dan suhu ekstrem dapat mempengaruhi produksi tanaman. Pada lahan terbuka modifikasi iklim mikro dilakukan dengan memberikan mulsa sebagai penutup permukaan lahan sehingga mampu memberikan karakteristik yang berbeda terhadap unsur-unsur iklim mikro, yang meliputi, kelengasan tanah, suhu tanah, serta suhu dan kelembapan udara. Penelitian ini menunjukkan bahwa otomatisasi irigasi tetes dapat berfungsi dengan baik. Alat ini mampu membaca suhu udara (°C), kelembapan udara (%), dan suhu tanah (°C) menggunakan sensor SHT10 dan DS18b20. Data hasil pembacaan sensor dan kondisi servo berhasil disimpan secara real time oleh data logger RTC DS3231 dalam format file .csv. Semua data dan aktivitas alat dapat dimonitor melalui MQTT Dashboard. Kelengasan tanah tertinggi terdapat pada tanah dengan menggunakan mulsa jerami yaitu sebesar 32% pada pukul 18:4:9 sore hari, Suhu tanah tertinggi terjadi pada perlakuan tanpa mulsa pada pukul 12:00 di siang hari sebesar 33.5 oC, diikuti suhu tanah pada perlakuan mulsa plastik sebesar 32 oC dan suhu tanah pada perlakuan dengan mulsa jerami sebesar 29,6 oC. Suhu udara yang diperoleh pada penelitian adalah  25,93 ˚C dengan kelembapan 79,72 %. Dari hasil yang diperoleh di lapangan, seledri bisa tumbuh dengan optimal pada rentang suhu dan kelembapan tersebut.

Abstract

The growing medium should have good water-holding capacity as it is essential for root growth. Roots need water to absorb nutrients and oxygen from the growing medium. Too much water can cause the roots to rot, while too little water can cause the roots to dry and die. Plants also absorb nutrients from the growing media through water. It is important to know the physical characteristics of planting media from organic waste from bamboo crafts and aren fronds as hydroponic growing media. The addition of cocopeat as a component of growing media offers a number of significant advantages, this is because cocopeat has an exceptional ability to retain water, which is essential for maintaining consistent moisture around plant roots. In addition, the porous structure of cocopeat improves aeration, allowing oxygen to reach the roots and preventing root rot. The slightly acidic to neutral pH properties of cocopeat (pH 5.0-6.8) are also ideal for most plants, creating an environment conducive to nutrient absorption. The results obtained physical characteristics of bamboo craft waste and palm fronds by adding cocopeat as a hydroponic growing medium have water content, bulk density, porosity and water holding capacity (WHC) values respectively 81.81%, 0.189 gr/cm3, 74.6%, and 450% for bamboo craft waste and 102.34%, 0.176 gr/cm3, 68.7% and 622% for palm fronds. Based on these results, it can be concluded that bamboo craft waste and palm fronds with the addition of cocopeat have high water content and are good for plant growth.

Abstract

Pengelolaan Sumber Daya Air (SDA) di Indonesia dihadapkan pada ketegangan dialektis antara kerangka hukum nasional yang cenderung sentralistik (Undang-Undang Nomor 17 Tahun 2019) dan keberadaan praktik kearifan lokal (seperti Subak dan Sasi) yang berbasis pada prinsip konservasi dan komunalitas. Paradigma sentralistik seringkali gagal menjamin keadilan ekologis dan alokasi air yang adil (intragenerational justice), sehingga memicu degradasi SDA dan konflik sumber daya. Penelitian hukum normatif ini bertujuan menganalisis mekanisme integrasi kearifan lokal ke dalam kerangka hukum, mengidentifikasi tantangan implementasi, serta mengkaji dampaknya terhadap keberlanjutan lingkungan dan kesejahteraan masyarakat. Metode yang digunakan adalah yuridis normatif dengan pendekatan perundang-undangan dan konseptual, menganalisis norma UU SDA, Putusan Mahkamah Konstitusi (MK), serta doktrin hukum lingkungan dan keadilan ekologis. Hasil dan Kesimpulan penelitian ini menegaskan bahwa terdapat tiga tantangan implementasi yang fundamental: hambatan birokrasi (Pasal 66 UU No. 17 Tahun 2019) yang mensyaratkan pengakuan Masyarakat Hukum Adat (MHA) melalui formalisme Peraturan Daerah, benturan kepentingan ekonomi yang masif, dan isu otentisitas kearifan lokal. Untuk mengintegrasikan kearifan lokal secara efektif, penelitian ini merekomendasikan rekonstruksi hukum melalui model Tata Kelola Bersama (Shared Governance) yang menempatkan MHA sebagai Co-Decision Maker. Integrasi harus diwujudkan dengan mengubah status pengakuan MHA menjadi deklaratif (bukan konstitutif) dan memperkuat Peraturan Desa (Perdes) sebagai instrumen legalitas operasional. Penerapan model ini terbukti memberikan dampak positif signifikan terhadap peningkatan kualitas air, biodiversitas, serta menjamin ketahanan pangan dan kesejahteraan masyarakat lokal, menegaskan bahwa kearifan lokal adalah prasyarat normatif bagi pengelolaan SDA yang berkeadilan dan berkelanjutan.
