Abstract

Ketidak-sesuian fungsi kawasan adalah masalah krusial di DAS Maros. Perubahan penggunaan lahan hutan menjadi lahan kering untuk budidaya pertanian tanpa memerhatikan kaidah konservasi tanah dan air telah menyebabkan terjadinya degradasi lahan. Usaha pengelolaan DAS Maros dapat dilakukan dengan memadukan antara kepentingan konservasi lahan dan air dengan peningkatan produksi pertanian. Langkah awalnya adalah dengan mengevaluasi kemampuan lahan. Tujuan penelitian ini untuk mengetahui kelas kemampuan lahan di wilayah DAS Maros dan merumuskan arahan penggunaan lahannya. Penelitian dilakukan dengan metode survei dan analisis contoh tanah. Survei dan pengambilan contoh tanah dilakukan di setiap satuan lahan yang memiliki ciri dan karakteristik yang sama, dengan terlebih dahulu membuat peta satuan lahan. Peta tersebut dihasilkan dari peta sistem lahan  yang bersumber dari RePprot skala 1:250.000 dengan empat karakteristik fisik lahan yaitu lereng, penggunaan lahan, jenis tanah, dan geologi. Faktor pembatas di setiap satuan lahan adalah sebagai dasar dalam menglasifikasi. Penulisan nama kelas kemampuan lahan dimulai dari tingkat ordo sampai sub-kelas sebagai penunjuk jenis pembatasnya. Hasil analisis data menunjukkan terdapat 11 kelas kemampuan lahan, yaitu : IIw, IIws, IIIe, IIIes, IIIews, IIIw, IVe, IVes, IVews, VIews, dan VIIes; dan terdapat 4,9% penggunaan lahan eksisting yang tidak sesuai dengan kemampuan lahannya. Penggunaan lahan yang tidak sesuai itu perlu dipulihkan dengan merumuskan arahan pengembangan penggunaan lahannya.

Abstract

Daun bambu telah terbukti mampu menetralkan limbah cair hasil pertanian maupun limbah cair industry tahu berdasarkan penelitian sebelumnya yang pernah dilakukan. Akan tetapi belum diketahui senyawa kimia apa saja yang terkandung di dalam daun bambu sehingga mampu berperan sebagai penetral limbah cair. Tujuan penelitian ini adalah untuk mengidentifikasi senyawa kimia yang terkandung dalam daun bambu segar. Penelitian ini dilakukan secara eksperimental di laboratorium dengan mengamati beberapa parameter yaitu kandungan Flavonoid, Alkaloid, Saponin, dan Tanin. Hasil uji kuantitatif diperoleh berat Flavonoid untuk sampel daun bambu segar sebesar 5,5744 gram atau 5,57 % berat sampel, Alkaloid sebesar 0,1421 gram atau 2,81 % berat sampel, sedangkan hasil uji kualitatif daun bambu segar positif mengandung Saponin dan Tanin..

Abstract

Cayenne pepper plants are one of the plants that are susceptible to excess and lack of water during their growth period. Lack of water can cause chili seeds to not grow optimally, so chili plant nurseries need ideal media to be able to provide optimal water. This research aims to determine the growth and duration of the permanent wilting point in the growth of chili plant seeds based on differences in planting media in the form of magot compost, soil containing pumice and paddy soil under conditions without watering. The treatment in this research used three different planting media, namely compost, pumice, and paddy soil media. Providing water to chili plants by watering 3 times a day and without watering. The research method uses experimental methods with observations in the greenhouse and there are three treatments, namely using magot compost, pumice and soil media. The parameters observed included growth in height, number of leaves, and width of the plant leaves as well as the length of time to the permanent wilting point. The data from the research were analyzed using ANOVA with the help of SPSS. The results of the research showed that the compost media had the best growth with a height of 9 cm, the number of leaves was 6 pieces, and leaf width 2.9 cm, while the permanent wilting point duration of the three media used was found in compost media, which experienced the longest permanent wilting point at the age of 10 days. So it can be concluded that the best planting medium is found in maggot compost media with the highest growth and longest wilting point.

Abstract

The threat of rice price inflation is increasingly having an impact on Indonesian society, especially the poor, both rural and especially urban. Several expert reviews state that the problem of rice prices continuing to rise is due to increasing rice consumption due to population growth which is not in line with the increase in rice production capacity which continues to decline, one of which is due to the conversion of agricultural land. Rice production in Central Lombok in 2020 reached 314 327.90 GKG or the equivalent of 21.6% of NTB province's rice production. Consumption: Rice consumption for the population of Central Lombok district with a population of 947,488 people multiplied by the rice requirement of 140 kg/person/year is 132,548 tons of rice per year from rice production of 178 103 tons or a surplus of 45,555 tons. However, the rice surplus condition was unable to withstand rice price inflation in early 2024, until it reached IDR 18,000 per kg. Pengadang Village, Central Praya District, Central Lombok Regency is one of the villages with the largest number of rice mills on the island of Lombok, with 10 units and has been a supplier of Bulog rice and some of it is traded to the islands of Bali and Java. This research aims to determine the difference in prices of grain and rice in the rice milling supply chain in Pengadang Village, Praya Tengah District, Central Lombok Regency. The research method uses percentage analysis of price differences and the factors that influence it. The research results show that the lowest supply chain profit is at the price of GKP grain in Merchant at 0.26% or Rp. 20/Kg GKP, and the highest profit in the GKG grain supply chain at the mill is IDR 495/Kg or the equivalent of 6.27%. The rice price profit in the rice milling supply chain is IDR. 30/Kg or equivalent to 0.30%, but there are other benefits from by-products in the form of fine bran and coarse bran amounting to Rp. 1,219/Kg GKG or the equivalent of 12.19%. The yield of GKP grain into GKG is at an average of 84.0% and the yield of GKG to rice is at an average of 64.02%, so that a rice price of IDR can be achieved. 16,000/Kg in the milling unit.

Abstract

Seawater intrusion in Gili Trawangan, North Lombok Regency, can be identified through groundwater salinity testing. This study aims to evaluate changes in groundwater salinity values as an indicator of seawater intrusion in the region. The test was conducted by taking well water samples and analyzing them at the Lombok Island Health Laboratory. The results showed that the groundwater salinity value before the water withdrawal project by PT Berkat Air Laut in 2012 was 5.00‰. During the groundwater withdrawal project period (2013-2022), the salinity value increased to 5.71‰, and post-project, the salinity value reached 6.07‰. These findings indicate that groundwater in Gili Trawangan was classified as brackish water from the start, with increasing salinity values indicating seawater intrusion. However, this increase is still in the low category, at 0.71‰ during the project and 0.36‰ post-project, so it is not classified as significant water pollution.

Abstract

Mineral soil has a high bulk density and is a limiting factor as a nursery medium. For the application of nursery media, planting media that is light, large water holding capacity are also needed. The magot compost comes from the Magot Lingsar unit the Regional TPA of NTB Province and the soil contains pumice an average of 68.2% comes from Tanak Beak Village, Central Lombok Regency, which has potential as a medium for nurseries. The purpose of this study was to identify the Bulk Density and water holding capacity of magot compost and soil containing pumice with the control variable of mineral soil from Labuapi, West Lombok Regency. Bulk density analysis method by analyzing dry weight per unit volume on soil rings and water capacity by analyzing wet weight minus dry weight. The subjects studied were magot compost with size < 2 mm, soil containing pumice size < 2 mm and control soil mineral rice fields. The results showed that the lowest Bulk Density was magot compost 0.42 gr/cm3, soil containing soil 0,64 gr/cm3, and rice field soil 1.42 gr/cm3, this was because magot compost was residue from waste. While the largest water holding capacity was soil containing pumice of 42.67%, magot compost 22.00%, and paddy soil 6.33%, caused by the number of macro and micro pores in pumice, whereas in magot compost water is bound to the humus surface. Suggestions for further research are the permanent wilting point time test on plant seeds.
